The loudspeaker peripheral and the loudspeaker base may work in two forms, namely, a combined form and a separate form. The following describes a schematic work procedure of the loudspeaker system during voice playback in combination with different forms.

<FIG> is a flowchart of a voice playback method of a loudspeaker system in a combined form according to an exemplary embodiment of this application. The voice playback method may be applied to the loudspeaker system shown in <FIG>. The method includes the following steps:
Step <NUM>. A loudspeaker base switches from a sleep state to an awake state when receiving a first press signal through a physical button.

The physical button may have its own name, for example, a G button, a super button, and a smart button.

The first press signal may be a single press signal. After being powered on, the loudspeaker base is in the sleep state.

A user applies the first press signal to the physical button. A control chip then switches from the sleep state to the awake state when receiving the first press signal through the physical button. The awake state is a state of monitoring the user's input voice.

Step <NUM>. The loudspeaker base enters a network configuration state when receiving a second press signal through the physical button.

The second press signal may be a long press signal lasting n seconds.

The loudspeaker base needs to be connected to an AI server on the Internet when being in an AI working state. If the network module of the loudspeaker base is a Wi-Fi communication module, the loudspeaker base needs to enter the network configuration state during an initial use.

In the network configuration state, the loudspeaker base is connected to a smartphone through the Wi-Fi communication module. A user inputs Wi-Fi access information in a current environment into the loudspeaker base through the smartphone. The Wi-Fi access information includes a service set identifier (SSID) and an access password. The loudspeaker base is then disconnected from the smartphone, and is connected to a wireless access point according to the Wi-Fi access information to access the Internet to communicate with the AI server.

Optionally, if an APP (for example, a game APP) corresponding to the role figure is run on the smartphone, the loudspeaker base further obtains and caches, in the network configuration state, a user account on the smartphone. The user account is used for uniquely identifying the identity of the user in the APP.

Step <NUM>. The loudspeaker base collects an input voice through a microphone assembly.

The loudspeaker base in the awake state collects an input voice of the user through a microphone assembly.

Step <NUM>. The loudspeaker base determines, according to an input voice collected by an array microphone, a sound source location of the input voice.

When the microphone assembly is an array microphone, the control chip locates the sound source location of the input voice according to receiving moments of input voices collected by different microphones of the array microphone.

Optionally, the plane of the base of the loudspeaker base is divided into n orientations, n being a divisor of <NUM> degrees. The control chip determines that the sound source location corresponding to the input voice is one of the n orientations.

Step <NUM>. The loudspeaker base drives a loudspeaker on a base plane to face the sound source location through a drive component.

The control chip drives, through the drive component, the loudspeaker on the base plane to face the sound source location.

Optionally, the control chip stores a current facing location of the base plane, and the control chip determines a target facing location of the base plane according to the sound source location, controls the number of revolutions and rotational direction of a motor in the drive component according to the current facing location and the target facing location, and controls the drive component to rotate according to the number of revolutions and rotational direction of the motor.

Step <NUM>. The loudspeaker base transmits the input voice to an AI server through a network module.

The loudspeaker base further transmits the input voice to the AI server. The AI server performs speech-to-text (STT) conversion on the input voice, then extracts a keyword in a word sequence obtained through conversion, and generates, according to the keyword, a first voice signal for AI feedback.

Optionally, the AI feedback is a capability of providing AI voice feedback based on a vertical field. The vertical field includes at least one of weather, alarm, chat, music, news, and FM broadcasting.

For example, as shown in <FIG>, the user may make a voice inquiry "What will the weather be like tomorrow?" to the loudspeaker base. After the loudspeaker base transmits the input voice to the AI server, the AI server generates a first voice signal "It's <NUM> degrees below zero tomorrow. It's freezing, man.

Step <NUM>. The loudspeaker base receives, through the network module, a first voice signal for providing AI feedback on the input voice by the AI server.

Optionally, the first voice signal is a signal in a voice form. Alternatively, the first voice signal is a signal in a text form. The loudspeaker base then performs TTS according to the signal in a text form to obtain a first voice signal in a voice form.

Step <NUM>. The loudspeaker base outputs the first voice signal to the loudspeaker through a second physical interface.

The control chip outputs the first voice signal to the loudspeaker through a data terminal in the second physical interface.

Step <NUM>. The loudspeaker receives the first voice signal through a first physical interface for playing.

The loudspeaker receives the first voice signal through a data terminal in the first physical interface for playing.

Step <NUM>. The loudspeaker base enters a game AI mode when receiving a third press signal through the physical button.

The third press signal may be a double-tap signal.

Optionally, the game AI mode is a mode that a game server provides AI strategy information in a battle to the loudspeaker system when the user runs a game APP corresponding to the role figure on a terminal.

Optionally, the loudspeaker base stores a user account on the smartphone in a network configuration stage. The user account is used for identifying the identity of the user in the APP. The APP may be a game APP corresponding to a role figure. For example, the APP is a multiplayer online battle arena (MOBA) game. The user account is an account of the user in the MOBA game. The role figure is a game role operated by the user in the MOBA game.

Step <NUM>. The loudspeaker base obtains, through the network module, a third voice signal for providing AI strategy feedback in a battle in a case that a user account is in an online game state.

When the user uses a smartphone (or a computer) to run an APP corresponding to a role figure, the APP transmits real-time running data to a backend server. The backend server generates a third voice signal for AI strategy feedback in a battle according to an AI strategy.

An example in which the APP is a MOBA game is used. When the user operates the game role for game, a smartphone <NUM> uploads game data to a backend server <NUM>. The backend server <NUM> analyzes the game data to determine that at present a better game strategy for the game role is to go to the jungle. The backend server <NUM> then transmits a third voice signal for providing AI strategy feedback in a battle to the loudspeaker system <NUM>. Schematically, as shown in <FIG>, the third voice signal is "Dude, take me to the jungle quick. Skill! Skill!".

Step <NUM>. The loudspeaker base outputs the third voice signal to the loudspeaker through the second physical interface.

The control chip outputs the third voice signal to the loudspeaker through the data terminal in the second physical interface.

Step <NUM>. A loudspeaker peripheral receives the third voice signal through the first physical interface for playing.

The loudspeaker peripheral receives the third voice signal through the data terminal in the first physical interface for playing.

Step <NUM>. The loudspeaker base obtains a role ID of a role figure corresponding to the loudspeaker.

The loudspeaker base obtains the role ID of the role figure corresponding to the loudspeaker peripheral through the data terminal in the second physical interface. The role ID may be stored in the Bluetooth module, the chip or the memory of the loudspeaker peripheral.

Step <NUM>. The loudspeaker base obtains voice data corresponding to the role ID, the voice data including at least one of an audio recording corpus, TTS synthesis elements, and emotionalized corpus features.

In an embodiment, the loudspeaker base stores voice data corresponding to each role ID. The loudspeaker base obtains corresponding voice data according to the obtained role ID.

In another embodiment, the backend server stores voice data corresponding to each role ID. The loudspeaker base obtains voice data corresponding to the role ID from the backend server according to the obtained role ID.

Step <NUM>. The loudspeaker base outputs a voice signal having a timbre corresponding to the role ID to the loudspeaker through the second physical interface according to the voice data corresponding to the role ID.

Optionally, when the voice data includes an audio recording corpus, the loudspeaker base may randomly or conditionally output a voice signal having a timbre corresponding to the role ID to the loudspeaker. When the voice data includes TTS synthesis elements, the loudspeaker base obtains, in a case of receiving a first voice signal, a second voice signal or a third voice signal in a text form, a first voice signal, a second voice signal or a third voice signal having a personalized timbre through conversion by the TTS synthesis elements. When the voice data includes the emotionalized corpus features, the loudspeaker base may output a voice signal having a timbre corresponding to the role ID to the loudspeaker according to a mood of the user or a triggering condition in a game program. The voice signal may be at least one of the first voice signal, the second voice signal, and the third voice signal.

The implementation form is not limited in this embodiment of this application.

In an exemplary embodiment, the loudspeaker base <NUM> includes a base housing. The base housing includes a system on chip (SOC). The SOC is a system or product formed by combining a plurality of integrated circuits with specific functions on a chip, and a complete hardware system and embedded software carried by the hardware system are included. That is, the function of an electronic system can be implemented on a single chip. Through the SOC, the loudspeaker may be used in one or more functions in data storage, data signal processing, acoustic capability processing, motor signal processing, wireless signal connection, and the implementation of data processing and interaction in combination with an operating system. The loudspeaker provided in this embodiment of this application may have a complete robot form. In addition to the foregoing basic functions, voice interaction, motion feedback, Artificial Intelligence (AI) guidance, and the like may further be implemented.

The voice interaction refers to that an external voice is recognized through the SOC and a corresponding response is thus made. Schematically, the user gives a voice instruction. The loudspeaker performs, after collecting voice data, a voice recognition on the voice data, to further give a corresponding response based on a recognition result. For example, the user gives a voice instruction "Play music" to the loudspeaker, then the voice data is recognized through the SOC, and the music is played based on a recognition result. In another example, the user gives a voice instruction of "What is the weather today" to the loudspeaker. The voice data is then recognized through the SOC. Current weather information is obtained based on a recognition result and is then played.

As an example, in addition to the recognition of a voice instruction given by a user to implement a voice interaction function, the loudspeaker may communicate with another loudspeaker to implement a voice interaction between different loudspeakers because the SOC may further implement a wireless signal connection.

The motion feedback refers to that an application scenario is recognized through the SOC and the loudspeaker peripheral <NUM> is controlled to move based on different application scenarios. For example, a current loudspeaker is in a music playback scenario. The loudspeaker peripheral <NUM> may be controlled, according to music rhythm, to move at different speeds.

In an exemplary embodiment, the loudspeaker base <NUM> further includes a first motion rotation mechanism. The first motion rotation mechanism is configured to drive the loudspeaker peripheral <NUM> connected to the loudspeaker base <NUM> to rotate.

In the first motion rotation mechanism, the foregoing motion feedback function may be implemented. Schematically, the first motion rotation mechanism includes a motor. The motor works under the control of the SOC chip, so as to control the movement speed of the loudspeaker peripheral <NUM>. In addition, the motion rotation mechanism may further be configured to implement sound source positioning. For example, when it is detected that a user gives a voice instruction, the location of the user is determined by positioning through the SOC. If the role figure <NUM> on the loudspeaker peripheral <NUM> currently does not face a direction in which the user gives the voice instruction, the motion rotation mechanism may drive the loudspeaker peripheral <NUM> to make the role figure <NUM> face the direction in which the user gives the voice instruction.

In an exemplary embodiment, the loudspeaker peripheral <NUM> provided in this embodiment of this application has the foregoing functions, in addition, a peripheral <NUM> on the loudspeaker peripheral <NUM> may further have an identity (ID) card (that is, electronic identification information). On such a basis, the loudspeaker base <NUM> may identify the ID card, so as to determine an identity corresponding to the role figure <NUM> on the loudspeaker peripheral <NUM>. On such as basis, a service matching the loudspeaker peripheral <NUM> can be provided. For example, in a game APP, a role voice actor recording original corpus, text to speech (TTS) speech synthesis, a dedicated emotionalized corpus features, and other functions may be provided for the identified identity.

To provide the role voice actor recording original corpus is to provide a voice audio recording corpus matching the identity. For example, the role figure <NUM> is a human storytelling figure. The storytelling figure has a personalized timbre. In view of this, original recording data of the object may be obtained. After recognizing the role figure <NUM>, the loudspeaker may use the original recording data when providing a voice playback function, so as to provide a timbre matching the role figure <NUM> to play the voice data.

The TTS speech synthesis is to synthesize a text into speech, and provide voice data of a matched timbre to the role figure <NUM>. The customized emotionalized corpus features may provide a corpus matching the role figure <NUM> after identifying the identity of the role figure <NUM>. An example in which the role figure <NUM> is a game character in a game is used. After recognizing the role figure <NUM>, a feature corpus of the game character may be obtained, and the feature corpus matching the role figure <NUM> is provided in providing a voice service.

In an exemplary embodiment, in addition to a manner of arranging a motion rotation mechanism on the loudspeaker base <NUM>, a first motion rotation mechanism may further be disposed on the loudspeaker peripheral <NUM>. The first motion rotation mechanism drives the loudspeaker peripheral <NUM> to rotate, so as to implement the foregoing motion feedback and sound source positioning function.

The AI guidance is to intelligently analyze the features of a role figure on the loudspeaker through an SOC to provide corresponding guidance information. For example, the role figure is a character in a game. After identifying the identity of the game character through the SOC, a game strategy based on the game character is provided and is played in a voice form during the user's game. In this way, an AI voice feedback function at a user level or an AI strategy analysis function in a battle for a game APP can be implemented. When implementing the AI strategy analysis function in a battle, the online user experience and offline user experience become consistent by using AI guidance because the role figure <NUM> on the loudspeaker peripheral <NUM> is the same as the appearance of a game role in a game.

The loudspeaker peripheral <NUM> is a smart peripheral tray component <NUM>. The loudspeaker base <NUM> is a smart peripheral base <NUM>. The two are independent of each other. As shown in <FIG>, the loudspeaker peripheral <NUM> is provided with an inserting part <NUM> formed by extending downward from the loudspeaker body <NUM>. As shown in <FIG>, the upper surface of the loudspeaker base <NUM> is provided with a limit groove <NUM> that is concave downward. As shown in <FIG>, the inserting part <NUM> is inserted into the limit groove <NUM>, to form an integrated structure of the loudspeaker peripheral <NUM> and the loudspeaker base <NUM>. In this way, the loudspeaker peripheral <NUM> can work separately, and includes a power supply (which is described in detail below). For example, the loudspeaker peripheral <NUM> may be used as a Bluetooth loudspeaker to receive a control command and a to-be-played voice of a main control device (for example, a mobile phone used as a control). The to-be-played voice is played through the Bluetooth loudspeaker. Alternatively, the loudspeaker peripheral <NUM> may be inserted into the loudspeaker base <NUM>, to receive a control command and a to-be-played voice of the loudspeaker base <NUM> for playing (which is described in detail below). When being inserted into the loudspeaker base <NUM>, the loudspeaker peripheral <NUM> is not a loudspeaker that can work independently. The loudspeaker peripheral <NUM> receives electric energy from a power supply in the loudspeaker base <NUM> for playing. Therefore, the loudspeaker may have two working modes, namely, working independently and receiving the power in the loudspeaker base <NUM> to play a to-be-played voice indicated in the loudspeaker base <NUM>. A two-mode working manner is formed, thereby improving the operation efficiency of the loudspeaker.

In addition, compared with a manner that a loudspeaker is connected to a base by glue or by a fastener, the appearance of the device is insusceptible to damage during detachment in a manner of an inserting part and a limit groove, thereby achieving the flexibility of use.

In an embodiment, as shown in <FIG>, the inserting part <NUM> includes an inserting platform <NUM> and an inserting joint <NUM> that extends downward from the inserting platform <NUM>. The cross section of the inserting platform <NUM> is smaller than the cross section of the loudspeaker body <NUM>, and the cross section of the inserting joint <NUM> is smaller than the cross section of the inserting platform <NUM>. Such a manner of gradually reducing cross sections facilitates the insertion between the loudspeaker peripheral <NUM> and the loudspeaker base <NUM>. The shape of the inserting platform <NUM> may be a square cylinder, a prismatic cylinder, a circular cylinder, an elliptic cylinder or the like. The shape of the inserting joint <NUM> may be a square cylinder, a prismatic cylinder, a circular cylinder, an elliptic cylinder, a cone gradually tapering from the top to bottom, a pyramid or the like.

Accordingly, as shown in <FIG>, the shape of the limit groove <NUM> may be a square cylinder, a prismatic cylinder, a circular cylinder, an elliptic cylinder, a cone gradually tapering from the top to bottom, a pyramid, or the like. The shape of the limit groove <NUM> matches the shape of the inserting joint <NUM>, that is, is consistent with the shape of the inserting joint <NUM>. In this way, as shown in <FIG>, when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, the loudspeaker peripheral <NUM> can be firmly combined with the loudspeaker base <NUM>, does not fall off easily, and can be easily detached.

As shown in <FIG>, a loudspeaker magnet part <NUM> is mounted at the bottom of the inserting platform <NUM>, and a loudspeaker pin interface <NUM> is mounted at the bottom of the inserting joint <NUM>. The magnet part may be a magnet, a lodestone or any other part that is magnetically attached by using the principle of magnetism. The loudspeaker magnet part <NUM> may be mounted at an edge of the bottom of the inserting platform <NUM> or may be mounted at another location of the bottom. As shown in <FIG>, the loudspeaker pin interface <NUM> includes an electric lead in the loudspeaker peripheral <NUM> for the loudspeaker peripheral <NUM> to be connected to the loudspeaker base <NUM>. The electric lead may be mounted right in the middle of the bottom of the inserting joint <NUM> or may be mounted at another location of the bottom.

As shown in <FIG>, a base magnet part <NUM> is mounted around the limit groove <NUM> on the upper surface of the loudspeaker base <NUM>. The base magnet part <NUM> may be a magnet, a lodestone or any other part that is magnetically attached by using the principle of magnetism. A base pin interface <NUM> may be mounted at the bottom of the limit groove <NUM>. In an embodiment, the base pin interface <NUM> may be mounted at the very center of the bottom. Alternatively, the base pin interface <NUM> may be mounted at another location of the bottom.

As shown in <FIG>, when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, the location of the base magnet part <NUM> corresponds to the location of the loudspeaker magnet part <NUM>. The base magnet part <NUM> and the loudspeaker magnet part <NUM> are magnetically attracted to each other, so that a connection is more stable. In addition, the location of the base pin interface <NUM> corresponds to the location of the loudspeaker pin interface <NUM> to implement joint of the interfaces, so that a connection between the loudspeaker peripheral <NUM> and the loudspeaker base <NUM> is more stable. Therefore, through the magnetic joint and the interface joint according to this application, the stability of the connection between the loudspeaker peripheral <NUM> and the loudspeaker base <NUM> is ensured twice. It may be clearly learned from a front view of a loudspeaker device after the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM> shown in <FIG>.

<FIG> is a pin diagram of a loudspeaker pin interface <NUM>. As shown in <FIG>, these pins include a first audio signal interface <NUM>, a first control signal interface <NUM>, and a first power signal interface <NUM>.

The first audio signal interface <NUM> is an interface for providing an audio signal for the speaker <NUM> to play. When the loudspeaker is used independently, the loudspeaker receives an audio signal to be played that is transmitted by a control device (for example, a mobile phone). When the loudspeaker is not used independently, the loudspeaker receives an audio signal to be played from the base. In an embodiment, the first audio signal interface <NUM> is an I2S interface.

The first control signal interface <NUM> is an interface for receiving a control signal by the loudspeaker peripheral <NUM>. When the loudspeaker is used independently, the loudspeaker receives a control command from a control device (for example, a mobile phone). When the loudspeaker is not used independently, the loudspeaker receives a control command from the loudspeaker base <NUM>. In an embodiment, the first control signal interface <NUM> is a serial interface.

The first power signal interface <NUM> is an interface for supplying power to the speaker <NUM>. When the loudspeaker is used independently, the loudspeaker is powered by a loudspeaker power supply <NUM>. When the loudspeaker is not used independently, the loudspeaker base <NUM> supplies power through the first power signal interface <NUM> to the loudspeaker for work.

<FIG> is a schematic diagram of a base pin interface <NUM> according to an embodiment of this application. <FIG> is a pin diagram of a base pin interface <NUM> according to an embodiment of this application.

As shown in <FIG>, the base pin interface <NUM> includes a second audio signal interface <NUM>, a second control signal interface <NUM>, and a second power signal interface <NUM>. The location of each pin in the base pin interface <NUM> matches the location of each pin in the loudspeaker pin interface <NUM> shown in <FIG>. When the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, the base pin interface <NUM> matches the loudspeaker pin interface <NUM>. In an embodiment, each pin (including the second audio signal interface <NUM>, the second control signal interface <NUM>, and the second power signal interface <NUM>) in the base pin interface <NUM> is a deformable probe, which can deform after being squeezed by an external force, so as to implement better contact. Each pin (including the first audio signal interface <NUM>, the first control signal interface <NUM>, and the first power signal interface <NUM>) in the loudspeaker pin interface <NUM> is a non-deformable probe, which does not deform when being in contact with another object. In this way, when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, a pin in the loudspeaker pin interface <NUM> abuts against to a corresponding pin in the base pin interface <NUM>. The pin in the base pin interface <NUM> deforms and the pin in the loudspeaker pin interface <NUM> does not deform, thereby achieving a stable contact between the pin in the base pin interface <NUM> and the pin in the loudspeaker pin interface <NUM>.

<FIG> is a schematic diagram that a pin on the base pin interface <NUM> is a deformable probe according to an embodiment of this application. Without abutting against any object, the maximum length of the pin on the base pin interface <NUM> during work may be <NUM>, a normal length during work may be <NUM>, and a length under maximum compression is <NUM> and the deformation is the largest at this time. By using the deformation of the pin on the base pin interface <NUM>, stable docking is implemented when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>.

As shown in <FIG>, in an embodiment, in addition to the base pin interface <NUM>, a connection detector <NUM> is further mounted at the bottom of the limit groove <NUM>. The connection detector <NUM> is a device detecting that the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, in other words, is a device detecting that a pin in the loudspeaker pin interface <NUM> is in contact with a pin in the base pin interface <NUM>. When a pin in the loudspeaker pin interface <NUM> is in contact with a pin in the base pin interface <NUM>, it does not represent that a pin in the loudspeaker pin interface <NUM> is docked to a corresponding pin in the base pin interface <NUM>. The connection detector <NUM> is used to enable a pin in the loudspeaker pin interface <NUM> is docked to a corresponding pin in the base pin interface <NUM> after detecting that the pin in the loudspeaker pin interface <NUM> is in contact with the pin in the base pin interface <NUM>. The first audio signal interface <NUM> is connected to the second audio signal interface <NUM>. The first control signal interface <NUM> is connected to the second control signal interface <NUM>. The first power signal interface <NUM> is connected to the second power signal interface <NUM>. Therefore, the transmission of various signals between the loudspeaker peripheral <NUM> and the loudspeaker base <NUM> is implemented when the loudspeaker peripheral <NUM> works in cooperation with the loudspeaker base <NUM>.

<FIG> is a pin diagram of a connection detector <NUM> according to an embodiment of this application.

In an embodiment, as shown in <FIG>, according to an embodiment of this application, the loudspeaker base <NUM> includes a rotary table <NUM> disposed on an upper surface, a base support <NUM> disposed in the middle of the base, and a base underframe <NUM> disposed at the bottom. The rotary table <NUM> is a motion rotation mechanism. As shown in <FIG>, during the mounting of the loudspeaker base <NUM>, the base support <NUM> is mounted on the base underframe <NUM>. Circuit parts such as a base power supply <NUM> and a base processing unit <NUM> shown in <FIG> are disposed inside the base support <NUM>. The rotary table <NUM> is disposed at an upper part of the base support <NUM>.

<FIG> shows a specific structure of a rotary table <NUM> according to an embodiment of this application. As shown in <FIG>, the base magnet part <NUM> is mounted on the rotary table <NUM> disposed on the upper surface of the loudspeaker base <NUM>. In this way, once the rotary table <NUM> rotates, the base magnet part <NUM> is driven to rotate, and the loudspeaker peripheral <NUM> may be driven to rotate since the base magnet part <NUM> and the loudspeaker magnet part <NUM> are connected through attraction. The rotary table <NUM> is provided with a motor <NUM>, a driving gear <NUM> driven by the motor, and a driven gear <NUM> driven by the driving gear <NUM>. The driven gear <NUM> drives the loudspeaker base <NUM> to rotate. In an embodiment, the motor <NUM> may be a stepper motor, and may be alternatively another motor. In this way, when receiving a control instruction sent by the base processing unit <NUM> shown in <FIG>, the motor <NUM> may adjust the rotation speed of the motor <NUM> according to the control instruction. The motor <NUM> drives the driving gear <NUM> to rotate. The driving gear <NUM> drives the driven gear <NUM> to rotate. The driven gear <NUM> drives the rotary table <NUM> to rotate. Therefore, the loudspeaker peripheral <NUM> is driven to rotate by using the base magnet part <NUM>. Thereby flexibly rotating the loudspeaker peripheral <NUM> according to the control instruction is achieved.

In an embodiment, as shown in <FIG>, the rotary table <NUM> may be provided with an angle measurement gear <NUM> meshing with both the driving gear <NUM> and the driven gear <NUM>. In this way, when the driving gear <NUM> and the driven gear <NUM> rotate, the angle measurement gear <NUM> may detect the rotation angle of the rotary table <NUM>, to generate an angle signal. The angle measurement gear <NUM> transmits the angle signal to the motor <NUM>. In this way, the motor <NUM> may adjust, according to the angle signal, the control signal outputted to the motor <NUM>, and adjust the rotation speeds of the driving gear <NUM> and the driven gear <NUM> based on the rotation speed change of the motor <NUM>, thereby accurately controlling the rotation angle of the loudspeaker peripheral <NUM>.

<FIG> is a pin diagram of an angle measurement gear according to an embodiment of this application.

In an embodiment, as shown in <FIG>, the loudspeaker base <NUM> includes a pickup <NUM> at an opening in the loudspeaker base <NUM>. The opening for the pickup <NUM> may be provided at any location in the loudspeaker base <NUM>, for example, an upper part or a side face of the loudspeaker base <NUM>, as long as the user's voice instruction can be collected. As shown in <FIG>, the loudspeaker base <NUM> further includes a base processing unit <NUM> configured to output a direction control signal for the motor <NUM> according to a sound signal collected by the pickup <NUM>. The base processing unit <NUM> is a processor <NUM>, and the pickup <NUM> is a microphone <NUM>. After receiving the collected sound signal, the pickup <NUM> transmits the sound signal to the base processing unit <NUM>. The base processing unit <NUM> recognizes the voice signal of a person from the collected sound signal, then determines the orientation of the person according to the voice signal of the person, so as to output a direction control signal to the motor <NUM> according to the orientation of the person. The motor <NUM> generates, according to the direction control signal, a rotation speed that drives the driving gear <NUM> and the driven gear <NUM>, so as to control the loudspeaker peripheral <NUM> to rotate toward a direction in which the person speaks. The motor <NUM>, the driving gear <NUM>, and the driven gear <NUM> are the motion rotation mechanisms. Therefore, according to this embodiment, when a person speaks, the loudspeaker peripheral <NUM> may flexibly rotate according to the orientation of the person, so as to enable the person to hear more clearly the sound played by the loudspeaker.

As shown in <FIG>, the upper surface of the loudspeaker base <NUM> is provided with a tuning ring <NUM> and a tuning ring slider sensor <NUM> (as shown in <FIG>) disposed under the tuning ring <NUM>. As shown in <FIG>, the tuning ring slider sensor <NUM> receives a slide signal generated on the tuning ring <NUM>, and transmits a volume change signal to the base processing unit <NUM> provided in the loudspeaker base <NUM>, so as to adjust an output of the base processing unit <NUM> to an audio output unit <NUM> and change the volume of audio outputted by the audio output unit <NUM> to the loudspeaker peripheral <NUM>.

As shown in <FIG>, in an embodiment, the tuning ring <NUM> is a circular ring with an opening, and may alternatively have another shape. When a user wants to turn up or turn down the volume of the loudspeaker peripheral <NUM>, the user may slide with a finger along the tuning ring <NUM> clockwise or counterclockwise. The tuning ring slider sensor <NUM> can sense a slide of the finger on the tuning ring <NUM>, that is, can receive a slide signal generated on the tuning ring <NUM>, and transmit a volume change signal to the base processing unit <NUM> provided in the loudspeaker base <NUM>.

In an embodiment, if the finger slides on the tuning ring <NUM> clockwise, a volume change signal represents a signal for turning up the volume. If the finger slides on the tuning ring <NUM> counterclockwise, a volume change signal represents a signal for turning down the volume. It may be alternatively set conversely.

In an embodiment, the tuning ring slider sensor <NUM> generates, according to a slide distance of the finger on the tuning ring <NUM>, a volume change signal that is directly proportional to the slide distance. A longer slide distance of the user indicates that the user wants a larger volume change, so as to flexibly control the volume according to the user's requirements. In another embodiment, the tuning ring slider sensor <NUM> generates, according to slide duration of the finger on the tuning ring <NUM>, a volume change signal that is directly proportional to the slide duration. Longer slide duration of the user indicates that the user wants a larger volume change, so as to flexibly control the volume according to the user's requirements.

After obtaining the volume change signal, the base processing unit <NUM> generates a control instruction to control the volume of audio outputted by the audio output unit <NUM> according to the volume change signal, and transmits the control instruction to the audio output unit <NUM>. The audio output unit <NUM> outputs a sound signal with an adjusted volume, and the sound signal is connected to the first audio signal interface <NUM> through the second audio signal interface <NUM>, for the speaker <NUM> in the loudspeaker peripheral <NUM> to play.

According to this embodiment, the tuning ring <NUM> and the tuning ring slider sensor <NUM> are disposed on the loudspeaker base <NUM>, so that the volume of the played sound of the loudspeaker peripheral <NUM> may be flexibly adjusted as required.

As shown in <FIG>, in an embodiment, the loudspeaker body <NUM> includes an outer housing <NUM> and an inner housing <NUM> located inside the outer housing <NUM>. The loudspeaker peripheral <NUM> is carried in the inner housing <NUM>. The outer housing <NUM> may be configured to form different forms, that is, different role figures <NUM>. For example, in a case of a human face loudspeaker, different faces may be changed by using faces of different people printed on the outer housing <NUM>, so that different role figures may be changed. For example, the outer housing <NUM> may printed with the face of Lv Bu or the face of Liu Bei, to form different character forms. The structure of the double housings makes it easy to change the form of the loudspeaker. When changing the form of the loudspeaker, the inner housing <NUM> may not be changed, and it is only necessary to change the outer housing <NUM>. In addition to the outer housing <NUM>, the loudspeaker body <NUM> may further include a tray body <NUM>. The outer housing <NUM> may be located on the tray body <NUM>, and the loudspeaker peripheral <NUM> is connected to the loudspeaker base <NUM> by the tray body <NUM>. For example, the tray body <NUM> has an inserting part <NUM> formed by extending downward. As shown in <FIG>, the upper surface of the loudspeaker base <NUM> is provided with a limit groove <NUM> that is concave downward. The inserting part <NUM> is inserted into the limit groove <NUM>, to form an integrated structure of the loudspeaker peripheral <NUM> and the loudspeaker base <NUM>.

As shown in <FIG>, in an embodiment, the inner housing <NUM> and the outer housing <NUM> are fixed by a first fixing member <NUM>. In an embodiment, the first fixing member <NUM> is a screw and a screw hole, and may be alternatively another fixing member. The screw is screwed into the screw holes in the outer housing <NUM> and the inner housing <NUM>, so that the outer housing <NUM> and the inner housing <NUM> are fixed.

The speakers <NUM> are disposed in two opposite side faces of the inner housing <NUM>. Speaker openings <NUM> are disposed in side faces of the outer housing <NUM> corresponding to the two opposite side faces of the inner housing <NUM>, to expose the speakers <NUM>. As for the purpose of the speaker opening <NUM>, the speakers do not change with the change of the different forms of housings, therefore, the speaker needs to be disposed on the inner housing <NUM>. In this case, the speaker opening <NUM> needs to be provided to expose the speaker <NUM>.

As shown in <FIG> and <FIG>, the loudspeaker peripheral <NUM> is provided with a cover body <NUM> disposed on the outer housing <NUM>. The cover body <NUM> has the function of preventing the dust from falling into the inside of the loudspeaker peripheral <NUM> and the function of decoration at the same time. For example, the cover body <NUM> may be used as a hat for the loudspeaker character. The outer housing <NUM> includes an outer housing main body <NUM> and a mounting opening <NUM> provided in a side face of the outer housing main body <NUM>.

The function of the outer housing main body <NUM> is to form a tight protection structure except for the mounting opening <NUM>, so that the loudspeaker peripheral <NUM> inside may be prevented from squeeze and collision. The function of the mounting opening <NUM> is to facilitate the entry and exit of internal components (for example, the inner housing <NUM>) during mounting. In an embodiment, the outer housing <NUM> is a cube. A rear side face of the cube has a mounting opening <NUM>, and the other five faces do not have openings, so that a continuous integrated structure, that is, the outer housing main body <NUM>, is formed.

The cover body <NUM> and the outer housing main body <NUM> are fixed through a second fixing member <NUM>. In an embodiment, the second fixing members <NUM> are a screw and a screw hole, and may be alternatively another fixing member. For example, the screw holes are provided at corresponding locations of the cover body <NUM> and the outer housing main body <NUM>, and the screw is screwed into the screw holes in the cover body <NUM> and the outer housing main body <NUM>, so that the cover body <NUM> is tightly fixed at the loudspeaker peripheral <NUM>. The cover body <NUM> and the outer housing main body <NUM> are fixed through the second fixing member <NUM>. Compared with a manner that a fastener extends from the bottom of the cover body <NUM> and the fastener is fastened into a fastener hole of the outer housing main body <NUM>, the cover body <NUM> does not fall off easily, so that a connection between the cover body <NUM> and the loudspeaker peripheral <NUM> is tighter.

In an embodiment, as shown in <FIG>, the outer housing <NUM> includes a sealing plate <NUM> covering the mounting opening. The outer housing main body <NUM> and the sealing plate <NUM> are fixed through a third fixing member <NUM>. In an embodiment, the third fixing member <NUM> is a screw and a screw hole, and may be alternatively another fixing member. For example, a screw hole is provided at each corner of the sealing plate <NUM>, and screw holes are correspondingly provided at four corners of the mounting opening <NUM>. The screw is screwed into the screw hole on the sealing plate <NUM> and is then screwed into the screw hole on the mounting opening <NUM>, so that the sealing plate <NUM> tightly seals the mounting opening <NUM> through the screw and the screw hole. By using such a structure, the content of the loudspeaker peripheral <NUM> may easily pass through the mounting opening <NUM> to enter or leave the loudspeaker peripheral <NUM>. The loudspeaker peripheral <NUM> is tightly sealed by using the third fixing member <NUM>, so that the content of the loudspeaker peripheral <NUM> may be prevented from falling out.

In addition, in an embodiment, as shown in <FIG>, the loudspeaker base <NUM> includes a base power supply <NUM>, a base processing unit <NUM>, and an audio output unit <NUM>, and further includes a tuning ring slider sensor <NUM>, a pickup <NUM>, and a motor <NUM>. The functions of the tuning ring slider sensor <NUM>, the pickup <NUM>, and the motor <NUM> are described in the foregoing, and the following describes the base power supply <NUM>, the base processing unit <NUM>, and the audio output unit <NUM>. The base power supply <NUM> may supply power to the loudspeaker peripheral <NUM> when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>. The base processing unit <NUM> is a core processing part in the base. The base processing unit <NUM> can generate an audio signal that needs to be played, and transmits the audio signal through the audio output unit <NUM> by using the second audio signal interface <NUM> and the first audio signal interface <NUM> to the speaker <NUM> in the loudspeaker peripheral <NUM> for playing. The base processing unit <NUM> may further recognize human voices from the voices collected by the pickup <NUM>, and outputs a direction control signal to the motor <NUM> according to the orientation of the human voice, the driving gear <NUM> and the driven gear are driven by using the motor <NUM>, so that the loudspeaker peripheral <NUM> may face a direction in which the person speaks. The base processing unit <NUM> may further respond, according to the tuning ring slider sensor <NUM>, to a volume change signal generated by a slide of a human finger on the tuning ring <NUM>, adjust an output of the audio output unit <NUM> accordingly, and eventually adjust the volume generated by the speaker <NUM> of the loudspeaker peripheral <NUM>. The audio output unit <NUM> is a device that forms, according to an instruction of the base processing unit <NUM>, a sound signal that needs to be played through the speaker. The instruction of the base processing unit <NUM> only indicates the sound that needs to be played and the volume of the sound, but the signal that needs to be played is formed by the audio output unit <NUM>. By using a circuit structure inside the loudspeaker base <NUM>, the content and volume of the outputted sound and the rotation angle of the loudspeaker peripheral <NUM> are accurately controlled.

As shown in <FIG>, the base power supply <NUM> is connected to the base processing unit <NUM>, and the base processing unit <NUM> is connected to the audio output unit <NUM>. The base power supply <NUM> is connected to the second power signal interface <NUM>, the base processing unit <NUM> is connected to the second control signal interface <NUM>, and the audio output unit <NUM> is connected to the second audio signal interface <NUM>. The second power signal interface <NUM> is an interface used for supplying, when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, power required for the loudspeaker peripheral <NUM> to play a sound. The second control signal interface <NUM> is an interface used for outputting a control signal to the loudspeaker peripheral <NUM> when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>. The second audio signal interface <NUM> is an interface used for outputting, to the loudspeaker peripheral <NUM> when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, a sound that needs to be played by the loudspeaker peripheral <NUM>.

In an embodiment, as shown in <FIG>, the loudspeaker peripheral <NUM> includes a loudspeaker power supply <NUM>, a loudspeaker processing unit <NUM>, and a speaker <NUM>. The loudspeaker power supply <NUM> is a power supply required to play a sound when the loudspeaker peripheral <NUM> works independently, that is, the loudspeaker peripheral <NUM> is not mounted on the loudspeaker base <NUM>. The loudspeaker power supply <NUM> does not work when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, and the loudspeaker peripheral <NUM> works relying on the base power supply <NUM> in the loudspeaker base <NUM>. The loudspeaker processing unit <NUM> is a core processing chip in the loudspeaker peripheral <NUM>, and completes data processing that needs to be performed when the loudspeaker peripheral <NUM> plays a sound. The loudspeaker power supply <NUM> is connected to the loudspeaker processing unit <NUM>. The loudspeaker processing unit <NUM> is connected to the speaker <NUM>. The first power signal interface <NUM>, the first audio signal interface <NUM>, and the first control signal interface <NUM> are all connected to the loudspeaker processing unit <NUM>. The first power signal interface <NUM> is connected to the second power signal interface <NUM>, to supply, to the loudspeaker peripheral <NUM> when the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, the power outputted by the base power supply <NUM>. The first audio signal interface <NUM> is connected to the second audio signal interface <NUM>, to transmit, to the loudspeaker peripheral <NUM> for playing, the to-be-played sound signal that is generated by the audio output unit <NUM> of the loudspeaker base <NUM>. The first control signal interface <NUM> is connected to the second control signal interface <NUM>, to transmit, to the loudspeaker peripheral <NUM>, the control signal transmitted by the loudspeaker base <NUM>. By using the foregoing structures, the sound playing of the loudspeaker peripheral <NUM> is adequately controlled.

As shown in <FIG>, in an embodiment, the loudspeaker power supply <NUM> and the first power signal interface <NUM> are connected to the base processing unit <NUM> by a switching circuit <NUM> disposed in the loudspeaker peripheral <NUM>. When the loudspeaker peripheral <NUM> is mounted on the loudspeaker base <NUM>, that is, the loudspeaker peripheral <NUM> does not work independently, a power signal can be received from the first power signal interface <NUM>. In this case, the switching circuit <NUM> is disconnected from the loudspeaker power supply <NUM>, and the loudspeaker peripheral <NUM> directly uses electric energy generated by the base power supply <NUM> in the loudspeaker base <NUM> to work. When the loudspeaker peripheral <NUM> is not mounted on the loudspeaker base <NUM>, that is, the loudspeaker peripheral <NUM> works independently, a power signal cannot be received from the first power signal interface <NUM>. In this case, the switching circuit <NUM> is disconnected from the first power signal interface <NUM>, and the loudspeaker peripheral <NUM> keeps the connection to the loudspeaker power supply <NUM>, and works by using the loudspeaker power supply <NUM> located inside the loudspeaker peripheral <NUM>. In this way, a manner of connecting and disconnecting of the switching circuit <NUM> located inside the loudspeaker peripheral <NUM> is used to ensure that the loudspeaker peripheral <NUM> may work in two forms, namely, a built-in power supply and an external power supply, thereby implementing a double-mode working.

An example in which the smart peripheral is a loudspeaker is used. This embodiment of this application provides a loudspeaker system. The loudspeaker system provides a loudspeaker and a loudspeaker base that can be combined, so that the loudspeaker and the loudspeaker base can be used in two forms, namely, a combined form and a separate form.

In the combined form, the overall weight of the loudspeaker system is relatively heavy, but an AI voice function can be implemented, to facilitate use of users in home, office, and other scenarios.

In the separate form, the loudspeaker system is divided into a loudspeaker and a loudspeaker base. The loudspeaker may be separately carried outdoors by a user and used as a Bluetooth loudspeaker. In addition, the loudspeaker may be designed into role figures of different IPs.
