Patent Description:
At present, with the development of science and technology, a screen thickness of a display apparatus such as a television is getting thinner and lighter, such that a volume and a mounting position of a component configured to play sound in the display apparatus are restricted. In order to meet the needs of lightening and thinning, a loudspeaker is arranged in the display apparatus, thereby resulting in that a sufficient space required for playing bass cannot be provided. The loudspeaker is arranged at a lower portion of the display apparatus, faces downwards, or on a back side of the display apparatus, and faces rearwards or sidewards.

It provides a display device which permits a large-sized display and is capable of efficiently performing the wiring of a speaker box by molding a casing for attaining the high precision and high molding efficiency. Connection terminal members connecting a display main body and a speaker box are disposed in terminal fitting recessed parts which are disposed along a butt part between a joint member and a first half-split casing and a butt part between the joint member and a second half-split casing. The connection terminal members on the part of outer peripheral flange parts constitute the same face with the casing and the joint member and, on the part of an exterior part are wired within a space part closed by the casing and the joint member.

<CIT> provides an electronic device including an enclosure and a speaker set received in the enclosure. The speaker set includes a shell, a pair of first and second speakers received in the shell. The first speakers provide high frequency acoustic output, and the second speakers provide low and middle frequency acoustic output. The shell includes a fixing plate. The fixing plate defines two tweet outlets aligning respectively with the first speakers, and two middle woof outlets aligning respectively with the second speakers. A central point of each middle woof outlet is located nearer to an imaginary central line of the fixing plate than a central point of each tweet outlet. A portion of each of the middle woof outlets is shaded by a portion of the electronic device. The tweet outlets are located beside the portion of the electronic device but not shaded by the portion.

<CIT> provides a speaker system in which generation of chattering noise can be prevented by preventing friction of a double speaker net due to a sound wave from a bass-reflex port. On the surface of a speaker box, a speaker panel, a cloth net and a punching net are arranged. The punching net is made of a material having high mechanical strength such as a metal and the cloth net is made of a cloth of dark color such as black or brown. A through hole is formed at a position of the speaker panel corresponding to a bass reflex port, and a spacer made of a flexible fibrous filter material having a three-dimensional skeletal structure is fitted in the through hole. The spacer relaxes vibration of the cloth net caused by a sound wave radiated through the bass-reflex port by pressing the cloth net against the punching net and prevents chattering noise by preventing the vibrating cloth net from hitting the punching net.

Further, the sound-image center is disposed at the center position of the display apparatus when playing sound, which solves the problem of separation of the sound and the image of the traditional television with a built-in loudspeaker, thus enhancing the quality of the sound and the image, and improving the user experience.

The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the disclosure. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the disclosure as recited in the appended claims.

In the related art, a loudspeaker is arranged at a lower portion of a display apparatus, and faces downwards, or arranged on a back side of the display apparatus, and faces rearwards or sidewards. In the above ways, a sound needs to reflected and diffused so as to be heard by a viewer, such that the sound quality is seriously damaged, thereby resulting in that the sound and a sound image received by a user watching the display apparatus are separated from a position of a screen. The sound image, also known as a virtual sound source or a sensory sound source, refers to a position of a sound source that is virtualized based on the sound heard by the user after he/she hears the sound. When using the display apparatus in the above related art, the user watches the image displayed by the screen and also listens to the sound output from the loudspeaker of the display apparatus. However, the position of the sound source virtualized based on the sound is not at a position of the image, thus resulting in a problem of separation of the sound and the image, which causes a poor user experience.

If the sound quality is improved through an external sound box, the cost will be increased and an additional space is required.

In order to solve the above technical problems, the present disclosure provides a sound box assembly <NUM>, which may be applied to a display apparatus <NUM>. The display apparatus <NUM> may be a television and includes a screen <NUM>. As illustrated in <FIG>, two sound box assemblies <NUM> are respectively arranged on both side portions of the display apparatus <NUM>, and upper and lower ends of the sound box assembly <NUM> may be flush with upper and lower ends of the display apparatus <NUM>, respectively, so as to increase an internal space of the sound box assembly <NUM>, thereby improving the quality of the played sound. Especially for a bass, the improvement of the space of the sound box may improve the listening experience and achieve a stunning bass effect. According to a size of the display apparatus <NUM>, a size of the sound box assembly <NUM> in a height direction, i.e. in a vertical up-down direction when the display apparatus <NUM> is arranged vertically, is consistent with the size of the display apparatus <NUM>. For example, in the display apparatus <NUM> with a <NUM> inch, <NUM> inch or larger screen, a volume of the sound box assembly <NUM> may be <NUM> liters or more, so as to provide a better sound quality. Moreover, the sound box assembly <NUM> is arranged on the side of the display apparatus <NUM>, so as to directly generate the sound to a front side of the display apparatus <NUM> when playing the sound, reduce an excessive interference of the sound reflected by walls or other objects on the direct sound of the sound box, obtain a good sense of positioning and a wide and deep sound field, and enable the user to hear the maximum, the most direct and the clearest details.

As illustrated in <FIG>, the sound box assembly <NUM> may include: a housing <NUM> in which a chamber is formed and to which a connecting part <NUM> is arranged, the connecting part <NUM> being configured to be connected with the display apparatus <NUM>; a loudspeaker <NUM> arranged in the chamber of the housing <NUM>, a sound-image center being disposed at a center position of the display apparatus <NUM> when playing sound. The loudspeaker <NUM> may include a squawker <NUM> arranged at a middle portion of the housing <NUM>, a woofer <NUM> and a tweeter <NUM>. One of the woofer <NUM> and the tweeter <NUM> is arranged above the squawker <NUM> and the other one of the woofer <NUM> and the tweeter <NUM> is arranged below the squawker <NUM>.

In this embodiment, the connecting part <NUM> may be directly connected with the housing <NUM> or fixedly connected with the housing <NUM> through a connector. Also, the connecting part <NUM> is further connected with the display apparatus <NUM>, such that the sound box assembly <NUM> is connected with the display apparatus <NUM>. The display apparatus <NUM> may include a moving part capable of moving to drive the connecting part <NUM> to move, so as to enable the sound box assembly <NUM> to move, which will be described in related embodiments later.

According to the arrangement of the sound box assembly <NUM> described above, the chamber formed in the housing <NUM> defines a relatively large space, so as to improve the sound quality, especially the bass generated by the woofer <NUM>, which may produce the bass effect with high quality through the chamber of the large space.

Moreover, in this embodiment, the numbers of the woofers <NUM>, the squawkers <NUM> and tweeters <NUM> may be one or more, respectively. In the drawings of the present disclosure, two woofers <NUM>, one squawker <NUM> and one tweeter <NUM> are illustrated as an example, but the present disclosure is not limited to this. The squawker <NUM> is disposed at the middle portion of the housing <NUM> and may be arranged adj acent to a middle position in a vertical direction of the display apparatus <NUM>. The woofer <NUM> may be disposed above the squawker <NUM> and the tweeter <NUM> may be disposed below the squawker <NUM>. Or, the woofer <NUM> may be disposed below the squawker <NUM> and the tweeter <NUM> may be disposed above the squawker <NUM>. Through the above arrangements, the sound-image center may be disposed at a middle height when the sound is being played, and the sound image may be disposed in a central position of the display apparatus <NUM> through left and right sound box assemblies <NUM>, such that when watching an image of the display apparatus <NUM>, the position of the virtual sound source that is heard is the same with the position of the image, which may bring a better experience to the user.

In an embodiment, as illustrated in <FIG>, the tweeter <NUM> may be disposed at the middle portion of the housing <NUM>, and be arranged below the squawker <NUM>. The tweeter <NUM> is arranged close to the squawker <NUM> and spaced from the squawker <NUM> by a first distance. The woofer <NUM> is disposed at an upper portion of the housing <NUM>, and is arranged further away from the squawker <NUM> than the tweeter <NUM>. The woofer <NUM> is spaced from the squawker <NUM> by a second distance. The second distance is greater than the first distance. In this embodiment, according to audio frequencies of different ranges and a range in which a common sound generally lies, the above arrangement can achieve that the overall sound image of the sound played from the loudspeaker <NUM> is disposed at the middle height, and the sound image is disposed in a center of the display apparatus <NUM> through the left and right sound box assemblies <NUM>, such that the sound and the image are on the same screen, that is, the virtual sound source is disposed at the screen <NUM> of the display apparatus <NUM>.

In an embodiment, as illustrated in <FIG> and <FIG>, the sound box assembly <NUM> may further include a bass reflex tube <NUM> arranged in the housing <NUM> and having a position corresponding to a position of the woofer <NUM>. In this embodiment, the bass reflex tube <NUM> is arranged in the housing <NUM>. The bass reflex tube <NUM> is a device that can transmit a vibration from rear to front of the loudspeaker, such that forward and rearward sound waves of the loudspeaker are both utilized, so as to improve the sound quality of the sound box. Moreover, according to the principle of the bass reflex tube <NUM>, the bass reflex tube <NUM> can especially enhance the performance of an electronic sound, and the bass may descend to <NUM>. Therefore, the bass reflex tube <NUM> is arranged at the position corresponding to the woofer <NUM>. That is, the woofer <NUM> is disposed at the upper portion of the housing <NUM>, and the bass reflex tube <NUM> is disposed at the lower portion of the housing <NUM>. Or, the woofer <NUM> is disposed at the lower portion of the housing <NUM>, and the bass reflex tube <NUM> is disposed at the upper portion of the housing <NUM>, so as to further ensure the overall sound image of the sound box assembly <NUM> is in the middle position.

In an embodiment, as illustrated in <FIG> and <FIG>, the sound box assembly <NUM> may further include a bracket <NUM> arranged in the housing <NUM>, a mounting hole <NUM> is formed in the bracket <NUM> and having a position corresponding to a position of the loudspeaker <NUM>, and the loudspeaker <NUM> is mounted in the mounting hole <NUM>. A sound guide hole <NUM> is formed in the bracket <NUM>, and a sound guide groove <NUM> is arranged on a back side of bracket <NUM> and having a position corresponding to that of the sound guide hole <NUM>. An opening of the sound guide groove <NUM> faces towards the woofer <NUM>, and the sound guide groove <NUM> is connected with the back side of the bracket <NUM> to form the bass reflex tube <NUM>.

In this embodiment, the bracket <NUM> may be arranged in the housing <NUM>, and the mounting hole <NUM> is formed in the bracket <NUM> for receiving the loudspeaker <NUM>. The number, position and opening size of the mounting hole <NUM> may be determined according to the numbers, positions and corresponding structures of the woofer <NUM>, the squawker <NUM> and the tweeter <NUM>. The loudspeaker <NUM> is mounted in the mounting hole <NUM>, a front surface of the loudspeaker <NUM> faces towards a front side, i.e. a side of the screen <NUM> of the display apparatus <NUM>, which displays the image, and a back surface of the loudspeaker <NUM> may be connected with a control circuit, a power supply circuit, or the like via the back side of the bracket <NUM> through a wiring <NUM>.

The sound guide hole <NUM> is also formed in the bracket <NUM>, and the sound guide groove <NUM> is arranged on the back side of the bracket <NUM> and having the position to that of the sound guide hole <NUM>. The sound guide groove <NUM> is connected with the back side of the bracket <NUM>, and has an opening facing towards the woofer <NUM> in its end, such that the vibration of the woofer <NUM>, the squawker <NUM> and the tweeter <NUM> on the back side of the bracket <NUM> can be collected, and then the sound can be transmitted to the front side through the sound guide hole <NUM> and be played.

In some embodiments, a connecting plate <NUM> may be arranged to the bracket <NUM>, and configured to be connected with the connecting part <NUM>. Since the loudspeaker <NUM> is mounted on the bracket <NUM>, the bracket <NUM> has a relatively large weight. The connecting part <NUM> is directly connected to the connecting plate <NUM>, which may reduce the force-supporting components, and the connecting part <NUM> directly achieves the support for the sound box assembly <NUM>. In some embodiments, as illustrated in <FIG> and <FIG>, the sound box assembly <NUM> may further include a reinforcing member <NUM>, which may be fixed to the bracket <NUM> for reinforcement, and the connecting part <NUM> may also be connected to the reinforcing member <NUM> to achieve a multi-point connection and a multi-point support, thereby enabling the connection of the sound box assembly <NUM> to be more stable and reliable.

In an embodiment, as illustrated in <FIG>, the sound box assembly <NUM> is connected to a moving part (not illustrated) of the display apparatus <NUM> through the connecting part <NUM>, and can be moved between a first position and a second position in a left-right direction of the display apparatus <NUM>. The first position is located on a back side of the screen <NUM> of the display apparatus <NUM>, and the second position is located on a left or right side of the screen <NUM>. The sound box assembly <NUM> further includes a distance sensor <NUM> arranged on a side of the housing <NUM> away from the screen <NUM>. If a distance detected by the distance sensor is less than or equal to a distance threshold, the sound box assembly is prohibited from moving to the second position.

The left-right direction generally refers to a linear direction of the left and right sides of the display apparatus <NUM> when the display apparatus <NUM> is in use and the screen <NUM> faces towards the front side. If the display apparatus <NUM> is arranged vertically, that is, when the screen <NUM> is arranged perpendicular to a horizontal plane, the left-right direction is a horizontal direction. In this embodiment, the sound box assembly <NUM> may be configured to move relative to the screen <NUM>, and the display apparatus <NUM> may include a moving part configured to move, a driving part configured to drive the moving part to move, etc. The sound box assembly <NUM> may be connected to the moving part through the connecting part <NUM>, and the display apparatus <NUM> may drive the moving part to move through the driving part, so as to drive the sound box assembly <NUM> to move between the first position and the second position. The first position may be located on the back side of the screen and adj acent to left and right ends of the screen <NUM>. When the sound box assembly <NUM> is in the first position, the user cannot observe the sound box assembly <NUM> from the front side of the display apparatus <NUM>. The second position may be located on a left or right side of the screen <NUM>. In some embodiments, the second position corresponds to the first position adjacent to the left end of the screen <NUM>, and extends leftwards beyond the back side of the screen <NUM>. When being in the second position, the sound box assembly <NUM> extends out of a boundary of the left side of the screen <NUM>, so as to expose the loudspeaker <NUM> completely. Thus, the user can observe the sound box assembly <NUM> from the front side of the display apparatus <NUM>, and the sound played by the sound box assembly <NUM> can also be transmitted to the user without being blocked and reflected. In some other embodiments, the second position corresponds to the first position adjacent to the right end of the screen <NUM>, that is, there is also a second position on the right side of the screen <NUM>, the principle of which is the same with that of the second position on the left side, and thus will not be repeated herein. In an audio output state, that is, when the sound needs to be played, for example, when the display apparatus <NUM> is turned on and ready to play a program or in the state of playing a program, the sound box assembly <NUM> may be moved to the second position so as to be exposed from the left or right side of the screen <NUM> of the display apparatus <NUM>, thus playing the sound to the front side, which avoids sound quality from being damaged. When the audio output state ends, that is, when the sound does not need to be played, for example, the display apparatus <NUM> is turned off or in a standby state, the sound box assembly <NUM> may be moved to the first position, that is, the sound box assembly <NUM> is located on the back side of the screen <NUM>, such that the appearance of the display apparatus <NUM> is simple and aesthetic. The sound box assembly <NUM> may be received in the housing of the display apparatus <NUM>. The above movement may be a linear movement or a flipping movement, etc..

In addition, the distance sensor <NUM> may be arranged on a side of the housing <NUM>, i.e. the side away from the screen <NUM>, for detecting whether there is an object on an outer side of the housing <NUM> and a distance to the object. As illustrated in <FIG>, there may be an object <NUM> arranged on both sides of the display apparatus <NUM>. When the sound box assembly <NUM> moves outwards, a collision may occur. Therefore, when it is detected by the distance sensor <NUM> that the distance to the object <NUM> is less than or equal to the distance threshold, the sound box assembly <NUM> may be prohibited from moving to the second position, so as to prevent the object from falling and colliding, and the sound box assembly <NUM> from being damaged. The distance threshold may be equal to or slightly greater than the distance between the second position and the first position, such that the movement is more reliable. For example, a distance extended by the sound box assembly <NUM>, i.e. the distance between the second position and the first position, is <NUM>. The distance threshold may be set as <NUM>, and a detection angle of the distance sensor <NUM> may be greater than or equal to <NUM> degrees so as to ensure the reliability of detection.

In an embodiment, the distance sensor <NUM> may include a first distance sensor <NUM> disposed at the lower portion of the housing <NUM>. Generally, the object is placed on the ground or table, so the object generally extends from bottom to top. In this embodiment, the first distance sensor <NUM> is disposed at the lower portion of the housing <NUM>, and faces outwards, thereby better detecting the object and avoiding the failure of detecting the object because of being arranged at a high position.

In an embodiment, the distance sensor <NUM> may further include one or more second distance sensors <NUM> disposed above the first distance sensor <NUM>. In some embodiments, the object placed on the side of the display apparatus <NUM> may have an irregular shape, such as some vases with a narrow bottom and a wide top, or objects extending from the side, such that the first distance sensor <NUM> arranged below may be unable to detect the object in the middle or above position. In this embodiment, in order to better detect the object and avoid the collision, one or more second distance sensors arranged above the first distance sensor <NUM> may be provided. For example, as illustrated in <FIG>, only one second distance sensor <NUM> may be arranged in the middle of the housing <NUM>, and the second distance sensor <NUM> may be <NUM> or other values higher than the first distance sensor <NUM>.

In an embodiment, as illustrated in <FIG>, <FIG>, <FIG> and <FIG>, the housing <NUM> may include a cloth net <NUM> covering an outer surface of the front side of the housing <NUM>. In this embodiment, the cloth net <NUM> may be made of canvas or other materials, and the appearance is simple by arranging a whole cloth net <NUM> outside the housing <NUM>. The cloth net <NUM> may cover the front side of the housing <NUM>, the upper side, the lower side and the outer side of the housing <NUM>, such that the observable surface is arranged as a whole.

In an embodiment, as illustrated in <FIG>, <FIG>, <FIG> and <FIG>, the housing <NUM> may further include a grid frame <NUM> and a rear housing <NUM>. The grid frame <NUM> is snapped with the rear housing <NUM> to define the chamber. The grid frame <NUM> includes a sound output area <NUM> having a position corresponding to the position of the loudspeaker <NUM>, and the cloth net <NUM> covers an outer surface of the grid frame <NUM>. In this embodiment, the grid frame <NUM> may be made of plastic and connected with the rear housing <NUM> by means of a snap. The connecting part <NUM> and the connecting plate <NUM> of the bracket <NUM> in the above embodiments may protrude out of the chamber. The grid frame <NUM> includes the sound output area <NUM> configured in a hollow or another manner, and the sound output area <NUM> has a position corresponding to the position of the loudspeaker <NUM>, so as to avoid the influence on the sound output of the loudspeaker <NUM>. In some embodiments, a portion of the grid frame <NUM> corresponding to the sound guide hole <NUM> also includes the sound output area <NUM>. The cloth net <NUM> may be covered on the outer surface of the grid frame <NUM> by means of glue spraying and adhering, so as to simplify the mounting. As illustrated in <FIG>, the front side of the housing <NUM> is mainly formed by the cloth net <NUM> and the grid frame <NUM>, and the cloth net <NUM> matches with the grid frame <NUM> so as to cover a front side and a side end surface of the grid frame <NUM>. <FIG> shows a partial schematic view of the cloth net <NUM> and the grid frame <NUM> bonded with each other. As illustrated in <FIG>, the cloth net <NUM> is covered on the front side (face A as illustrated in <FIG>) and the side end face (face B as illustrated in <FIG>) of the grid frame <NUM>. Through this arrangement, the appearance of the sound box assembly <NUM> may have an integral visual effect, and the user experience may be improved. In addition, as illustrated in <FIG>, the distance sensor <NUM> is arranged on the side of the sound box assembly <NUM>. Specifically, as illustrated in <FIG>, a through hole is formed in the side end face of the grid frame <NUM>, and a through hole is also formed in the cloth net <NUM> in a corresponding position. The first distance sensor <NUM> is arranged in the housing <NUM>, i.e. on an inner side of the through hole formed in the side end face of the grid frame <NUM>. The first distance sensor <NUM> may be mounted to the cloth net <NUM> by means of snap-fit, and pass through the through holes of the grid frame <NUM> and the cloth net <NUM>, so as to detect the external object and the distance to the external object. The mounting principle of the second distance sensor <NUM> is the same with that of the first distance sensor <NUM>, which will not be repeated herein.

Based on the same conception, the present disclosure also provides a display apparatus <NUM>. The display apparatus <NUM> includes two sound box assemblies <NUM> according to the above embodiments, the two sound box assemblies <NUM> are arranged on both sides of the display apparatus <NUM>, respectively, and upper and lower ends of the sound box assembly <NUM> are flush with upper and lower ends of the display apparatus <NUM>, respectively, so as to increase an internal space of the sound box assembly <NUM>, thereby improving the quality of the played sound. Especially for a bass, the improvement of the space of the sound box may improve the listening experience and achieve a stunning bass effect. Moreover, the sound box assembly <NUM> is arranged on the side of the display apparatus <NUM>, so as to directly play the sound to the front side of the display apparatus <NUM> when playing the sound, reduce an excessive interference of the sound reflected by walls or other objects on the direct sound of the sound box, obtain a good sense of positioning and a wide and deep sound field, and enable the user to hear the maximum, the most direct and the clearest details.

The first position is disposed on the back side of the screen <NUM> of the display apparatus <NUM>, and the second position is disposed on the left or right side of the screen <NUM>.

The audio output method <NUM> according to the embodiments of the present disclosure may obtain the audio output state of the sound box assembly <NUM> according to a current state of the display apparatus <NUM>. For example, when the display apparatus <NUM> is turned on and music needs to be played, the sound box assembly <NUM> is in the audio output state, ready to play or playing sound, and thus the sound box assembly <NUM> is driven to move from the first position to the second position through the moving part and the driving part of the display apparatus <NUM>, such that the sound box assembly <NUM> is exposed, and the loudspeaker may output the sound forwards, thereby ensuring the sound quality. If there is no need to play the sound at present, for example, when the display apparatus <NUM> is turned off or in a standby state, the sound box assembly <NUM> may be moved to the first position, i.e. on the back side of the screen <NUM>, such that the appearance of the display apparatus <NUM> is simple and aesthetic. The sound box assembly <NUM> may be received in the housing of the display apparatus <NUM>, and the above movement may be a linear movement or a flipping movement, etc..

In an embodiment, as illustrated in <FIG>, the audio output method <NUM> may include step S34. In step S34, a distance detected by the distance sensor is acquired. If the distance detected by the distance sensor is less than or equal to the distance threshold, step S35 is executed. In step S35, the sound box assembly is stopped from being driven to move to the second position. If the distance detected by the distance sensor is greater than the distance threshold, step S32 is executed. Step S34 may be executed again when the sound box assembly <NUM> is in the audio output state. In this way, it is possible to avoid collisions which occur when the sound box assembly <NUM> is moved outwards with objects being arranged on both sides of the display apparatus <NUM>.

Based on the same concept, the embodiments of the present disclosure also provide an audio output device <NUM>.
