DETAILED DESCRIPTION
Configurations shown in embodiments enumerated in the present specification and the drawings are just exemplary embodiments of the present disclosure, and it should be understood that there are various modified examples capable of replacing the embodiments of the present specification and the drawings at the time of filing the present application.
Reference will now be made in detail to the embodiments of the present disclosure, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like elements throughout.
FIG. 1 is a view illustrating a control flow of a sound module according to an embodiment of the present disclosure.
Referring to FIG. 1, a sound module 10 according to an embodiment of the present disclosure includes a manipulation unit 20 through which sound information is input from a user, a sound input unit 80 through which a sound is input from the user, a communication unit 70 that downloads sound data from an external server, a storage unit 60 that stores the sound, a display unit 30 that displays operating information of the sound module 10, a sound output unit 40 that outputs the sound, and a controller 50 that controls an operation of the sound module 10.
The manipulation unit 20 may be implemented with a membrane switch, a button type switch, a dial, or a touchpad. The sound information is input to the manipulation unit 20 from the user. That is, the user may input a sound to be input in a particular shape through the manipulation unit 20. For example, when the manipulation unit 20 is implemented with a keypad, the keypad allows musical scales and beats of sounds to correspond to numbers, and the user inputs numbers corresponding to musical scales and beats of desired sounds through the keypad, thereby inputting sound information.
The sound input unit 80 may be implemented with a microphone that converts a sound signal into an electrical signal. The sound input unit 80 receives sound from the user. For example, the sound input unit 80 receives sound signals, such as a user's voice, sounds of nature, and a crying sound of an animal, converts the sound signals into electrical signals and outputs the electrical signals corresponding to the sound signals.
The communication unit 70 may access a local area network (LAN) or a wide area network (WAN), such as the Internet, intranet, or Ethernet, through a near field communication or wired communication, such as wireless fidelity (Wi-Fi), Bluetooth, Zigbee, or near field communication (NFC), and may receive sound data from the external server disposed on the LAN or WAN. The sound data may include sound effects, music in compressed audio format, ring tones, song snippets, or any other type of audio data stored by a user or obtainable from the Internet.
The storage unit 60 stores program or data for controlling the sound module 10. The storage unit 60 may adopt volatile memory, such as dynamic random-access memory (DRAM) or static random-access memory (SRAM), in addition to nonvolatile memory, such as a magnetic disc or a solid state disk (SSD). In particular, the storage unit 60 stores the sound data that is input or received through the above-described manipulation unit 20, sound input unit 80, or communication unit 70.
The controller 50 controls the operation of the sound module 10. In detail, the controller 50 may control the operation of the sound module 10 to convert the sound information input through the manipulation unit 20 into sound data and then to store the converted sound data in the storage unit 60 or to convert a sound input through the sound input unit 80 into sound data and then to store the converted sound data in the storage unit 60 or to store the sound data received through the communication unit 70 in the storage unit 60.
Also, if an operating sound output condition is satisfied, the controller 50 controls the sound output unit 40 that will be described below, to output a sound corresponding to the satisfied operating sound output condition. In this way, if the operating sound output condition is satisfied, sound output by the sound module 10 so as to inform the user of an operating situation is referred to as an operating sound, and sound data of the operating sound output to correspond to the occurrence of a particular situation from among a plurality of sound data stored in the storage unit 60 is referred to operating sound data.
Such an operating sound may be selected by the user. That is, the user may select a particular sound from among the plurality of sounds stored in the storage unit 60 and designate the selected sound as an operating sound corresponding to the operating sound output condition. In this case, the controller 50 controls the sound output unit 40 to output the designated sound (operating sound) if the operating sound output condition is satisfied. For example, the user may set a siren sound from among the plurality of sounds stored in the storage unit 60 as an operating sound corresponding to opening a door of a refrigerator and may set a voice of a person “Washing has been completed” as an operating sound corresponding to completing washing of a washing machine. The set voice may be stored as the voice of the user, the user's child, or a favorite celebrity of the user.
The display unit 30 may be implemented with a liquid crystal display (LCD) or light emitting diode (LED) display device. When the user inputs sound information, such as a musical scale and a beat of sound through the manipulation unit 20, the display unit 30 may display the input sound information using musical notes through which the user can check the sound information.
The sound module 10 illustrated in FIG. 1 includes the manipulation unit 20 and the display unit 30 separately. However, aspects of the present disclosure are not limited thereto, and the sound module 10 may include a touch screen panel (TSP) in which the display unit 30 and the manipulation unit 20 are integrally formed.
The sound output unit 40 may be implemented with a speaker that converts an electrical signal (operating sound data) output from the controller 50 that will be described below into a sound signal. The sound output unit 40 outputs the operating sound according to a control signal of the controller 50. In detail, the sound output unit 40 receives the operating sound data corresponding to a user's voice, sounds of nature, sound effects, music, or a crying sound of an animal and outputs the user's voice, the sounds of nature, the sound effects, the music, or the crying sound of an animal corresponding to the received operating sound data.
Hereinafter, examples in which the sound module 10 of FIG. 1 is applied to home appliances will be described.
FIG. 2 is a view illustrating the exterior of a refrigerator including the sound module illustrated in FIG. 1.
Referring to FIG. 2, a refrigerator 100 includes a body 110 that constitutes the exterior of the refrigerator 100, a storage compartment (not shown) that is disposed in the body 110 and stores food, and doors 113a and 113b that cause the storage compartment (not shown) to be shielded from the outside. Although not shown, the refrigerator 100 includes a cooling unit (not shown) that cools the storage compartment (not shown).
The storage compartment (not shown) is partitioned off into a refrigerator compartment (not shown) and a freezer compartment (not shown) by a central partition. The refrigerator compartment (not shown) and the freezer compartment (not shown) are shielded from the outside by a pair of doors 113a and 113b. 
A dispenser 111 is disposed in one of the pair of doors 113a and 113b and dispenses filtered water stored in a water tank (not shown) disposed in the refrigerator 100 or ice stored in an ice tray (not shown). Control panels 120 and 130 are disposed on an upper side of the dispenser 111, receive operating instructions from the user, and display operating information of the refrigerator 100. The control panels 120 and 130 will now be described in detail.
The cooling unit (not shown) includes a compressor (not shown) that compresses a refrigerant, a condenser (not shown) that condenses the compressed refrigerant, an expansion valve (not shown) that expands and decompresses the condensed refrigerant, and an evaporator (not shown) that evaporates the decompressed refrigerant. The cooling unit (not shown) cools the storage compartment (not shown) using latent heat absorbed by the refrigerant when the refrigerant is evaporated by the evaporator (not shown).
FIG. 3 is a view illustrating a control flow of the refrigerator including the sound module of FIG. 1.
Referring to FIG. 3, the refrigerator 100 includes a temperature sensing unit 115 that detects the temperature of the storage compartment (not shown), a manipulation unit 120 through which operating instructions or sound information are input from the user, a sound input unit 180 through which voice instructions or sounds are input from the user, a driving unit 117 that drives a compressor 119, the compressor 119 that compresses and circulates the refrigerant, as described above, a display unit 130 that displays operating instructions input from the user and operating information of the refrigerator 100 corresponding to the operating instructions, a sound output unit 140 that outputs an operating sound of the refrigerator 100, a communication unit 170 that receives sound data from an external server (not shown), a storage unit 160 that stores a program or data for controlling the refrigerator 100, and a controller 150 that controls the operation of the refrigerator 100.
The manipulation unit 120, the sound input unit 180, the display unit 130, the sound output unit 140, the communication unit 170, and the storage unit 160 are the same as the manipulation unit 20, the sound input unit 80, the display unit 30, the sound output unit 40, the communication unit 70, and the storage unit 60, which have been described with reference to FIG. 1. Thus, detailed descriptions thereof will be omitted.
The temperature sensing unit 115 includes a freezer compartment temperature sensor (not shown) that is disposed in the freezer compartment (not shown) and senses the temperature of the freezer compartment (not shown), and a refrigerator compartment temperature sensor (not shown) that is disposed in the refrigerator compartment (not shown) and senses the temperature of the refrigerator compartment (not shown). The freezer compartment temperature sensor (not shown) and the refrigerator compartment temperature sensor (not shown) each may adopt a thermistor, an electrical resistance value of which varies according to temperature.
Also, the temperature sensing unit 115 provides electrical signals corresponding to temperatures detected by the freezer compartment temperature sensor (not shown) and the refrigerator compartment temperature sensor (not shown) to the controller 150 that will be described below.
The driving unit 117 drives the compressor 119 according to the control signal of the controller 150 that will be described below. In detail, the driving unit 117 generates a driving current for driving the compressor 119 according to the control signal output from the controller 150 and provides the generated driving current to the compressor 119.
The compressor 119 operates by the driving current provided by the driving unit 117, compresses the refrigerant evaporated by the evaporator (not shown), as described above, and forcibly transfers the compressed refrigerant to the condenser (not shown) so that the refrigerant can circulate the cooling unit (not shown).
The controller 150 controls the operation of the refrigerator 100. In detail, the controller 150 compares the temperature of the storage compartment (not shown) sensed by the temperature sensing unit 115 with a setting temperature set by the user, and if the temperature of the storage compartment (not shown) exceeds the setting temperature, the controller 150 controls the driving unit 117 and activates the compressor 119 so as to cool the storage compartment (not shown). That is, the controller 150 causes the temperature of the storage compartment (not shown) to be maintained at the setting temperature set by the user so that food stored in the storage compartment (not shown) does not spoil.
In addition, if an operating sound output condition is satisfied, the controller 150 controls the sound output unit 140 to output an operating sound corresponding to the satisfied condition. For example, if the temperature of the storage compartment (not shown) rises abnormally, the controller 150 controls the sound output unit 140 to output an operating sound corresponding to malfunction of the refrigerator 100. As a second example, if a door of the refrigerator 100 is opened for a long time, the controller 150 controls the sound output unit 140 to output an operating sound corresponding to opening the door. More specifically, if the door is left open for a long time, the controller 150 may control the sound output unit 140 to output a portion of the song “Close the Door” by Teddy Pendergrass, which is stored in storage unit 60. As a third example, if the user changes the setting temperature of the storage compartment (not shown), the controller 150 controls the sound output unit 140 to output an operating sound corresponding to a change in the setting temperature.
In addition, the controller 150 may control the sound output unit 140 to generate an operating sound when a noise occurs in the refrigerator 100, like when the compressor 119 operates or an ice-making device makes ice. That is, when it is expected that a noise generated in the refrigerator 100 may create an unpleasant feeling in the user, the controller 150 may control the sound output unit 140 to generate the operating sound so as to mask the noise thus relieving the unpleasant feeling of the user and informing the user of operating information of the refrigerator 100.
As described above, the configuration of the refrigerator 100 including the sound module 10 illustrated in FIG. 1 has been described. Hereinafter, the case that the refrigerator 100 including the sound module 10 of FIG. 1 receives and stores a sound and sets the stored sound as an operating sound, will be described.
FIGS. 4A and 4B are views illustrating the case that an operating sound is input to the refrigerator 100 including the sound module 10 of FIG. 1 through an input unit.
In order to input a sound through the manipulation unit 120, numbers may be designated as operating sound information corresponding to a musical scale and a beat of the sound.
(a) and (b) of FIG. 4A illustrate a method of designating numbers corresponding to the musical scale and the beat of the operating sound.
As illustrated in (a) of FIG. 4A, number “1” may be designated as a musical scale “do”, number “2” may be designated as a musical scale “re”, and number “3” may be designated as a musical scale “mi”. In this manner, numbers from 1 to 10 may be designated from “do” that is a low musical scale to “mi” that is a relatively high musical scale. Also, as illustrated in (b) of FIG. 4A, number “1” may be designated as a one-eighth beat, number “2” may be designated as a quarter beat, number “3” may be designated as a half beat, and number “4” may be designated as one beat.
Sound illustrated in (c) of FIG. 4A will be displayed as shown in (d) of FIG. 4A, using methods illustrated in (a) and (b) of FIG. 4A.
As illustrated in (c) of FIG. 4A, sound to be input by the user includes high “re” having a half beat, high “re” having a quarter beat, high “mi” having a quarter beat, high “mi” having a half beat, high “mi” having a half beat, high “re” having a half beat, high “re” having a quarter beat, high “do” having a quarter beat, and high “do” having a half beat.
As illustrated in (d) of FIG. 4A, the user may input musical scale information of 9 and beat information of 3 in correspondence to high “re” having a half beat, musical scale information of 9 and beat information of 2 in correspondence to high “re” having a quarter beat, and musical scale information of 10 and beat information of 2 in correspondence to high “mi” having a quarter beat. In this manner, the user may input (9, 3), (9, 2), (10, 2), (10, 3), (10, 3), (9, 3), (9, 2), (8, 2), and (8, 3) through the manipulation unit 120, thereby inputting sound information corresponding to the sound illustrated in (c) of FIG. 4A.
FIG. 4B illustrates the case that sound information is input through a touch screen panel (TSP) of the refrigerator 100 including the sound module 10 of FIG. 1.
As illustrated in FIG. 4B, the manipulation unit 120 and the display unit 130 are integrally formed, thus constituting TSPs 120 and 130. The TSPs 120 and 130 may be implemented by disposing the manipulation unit 120 including a capacitive sensor for sensing touch of a part of the user's body on the display unit 130. Also, the TSPs 120 and 130 may display an icon corresponding to an operating instruction that may be input by the user, using the display unit 130, and if the user touches a portion corresponding to the icon, the capacitive sensor of the manipulation unit 120 detects a position touched by the user and identifies the operating instruction input by the user based on the detected position.
If the user inputs a sound information input instruction through the TSPs 120 and 130, the display unit 130 of the refrigerator 100 displays a sound information input screen 131 illustrated in FIG. 4B. The sound information input screen 131 includes a sound display region 131a in which a sound input by the user is displayed using a manuscript paper and musical notes, a keypad region 131c through which a musical scale and a beat are input from the user, and a sound information display region 131b in which the musical scale and the beat input by the user through the keypad region 131c are displayed.
If a user's touch is sensed by the manipulation unit 120 including the capacitive sensor, the refrigerator 100 calculates a position at which the user's touch is sensed, determines whether the calculated position is within the keypad region 131c of the sound information input screen 131, and if it is determined that the calculated position is within the keypad region 131c, the refrigerator 100 determines which key from among a plurality of keys included in the keypad region 131c. In other words, the user may touch a region corresponding to one from among the plurality of keys displayed in the keypad region 131c, thereby inputting musical scale information and beat information of the operating sound. For example, as illustrated in FIG. 4A, if the user touches regions corresponding to number 9 and number 3 included in the keypad region 131c continuously, the refrigerator 100 displays number 9 and number 3 in the sound information display region 131b of the TSPs 120 and 130 and displays a musical note corresponding to high “re” having a half beat in the sound display region 131a. 
In this way, the refrigerator 100 receives sound information from the user using the TSPs 120 and 130 in which the manipulation unit 120 and the display unit 130 are integrally formed and displays a sound corresponding to the input sound information as musical notes. Thus, the user may check sound input by the user oneself.
FIGS. 5A and 5B are views illustrating the case that sound data is received through a communication unit of the refrigerator 100 including the sound module 10 of FIG. 1.
Referring to FIG. 5A, which illustrates the case that the sound data is received from an external server S disposed in a WAN, the refrigerator 100 may access a home gateway G through the communication unit 170 and may also access the Internet I through the home gateway G. If the refrigerator 100 accesses the Internet I, the refrigerator 100 may download the sound data stored in the external server S from the external server S on the Internet I. The refrigerator 100 may store the sound data downloaded from the external server S in the storage unit 160. In detail, sound data regarding various sounds, such as sounds of nature, a voice of a person, a crying sound of an animal, and an artificial sound, may be stored in the external server S in various forms, such as a wave file way and a compressed file, for example, mp3. The user may access the external server S through the communication unit 170 of the refrigerator 100 and then may download user's desired sound data and may store the downloaded sound data in the storage unit 160 of the refrigerator 100. In addition, the user may select the user's desired sound data from among sound data stored in the storage unit 160 and may set the selected sound data as an operating sound.
Referring to FIG. 5B, which illustrates the case that a sound is received using a mobile terminal M through which NFC can be performed, the refrigerator 100 may access the mobile terminal M through the communication unit 170. For example, the refrigerator 100 may access the mobile terminal M using an NFC module (not shown) disposed on the communication unit 170. Also, the refrigerator 100 may receive a sound from the user through a user interface disposed on the mobile terminal M. As illustrated in FIG. 5B, a TSP may be disposed on the mobile terminal M, and keys may be displayed on the TSP of the mobile terminal M according to a user's selection.
In this case, if the user touches keys corresponding to user's desired musical scales from among the keys displayed on the TSP of the mobile terminal M, the musical scales are transferred to the refrigerator 100 through NFC between the mobile terminal M and the refrigerator 100. In this manner, the user may input desired sound through the TSP of the mobile terminal M, and the sound is transferred to the refrigerator 100 through NFC.
FIG. 6 is a view illustrating the case that an operating sound is input to the refrigerator 100 including the sound module 10 of FIG. 1 through a sound input unit.
Referring to FIG. 6, a sound signal may be input to the refrigerator 100 through the sound input unit 180. In detail, if the user inputs a sound recording instruction through the TSPs 120 and 130 of the refrigerator 100, the refrigerator 100 activates the sound input unit 180 and stores the sound signal input through the sound input unit 180 in the storage unit 160. For example, as illustrated in FIG. 6, the user may allow his/her own voice to be stored in the refrigerator 100 and may set his/her own voice as the operating sound. Alternatively, the user may store the voice of the user's child or a favorite celebrity of the user.
The user may designate a particular sound from among a plurality of sounds received through the manipulation unit 120, the communication unit 170, or the sound input unit 180 as the operating sound corresponding to an operating sound output condition. In other words, the user may select one from among the plurality of sounds stored in the storage unit 160 as the operating sound corresponding to a particular condition through the manipulation unit 120. In detail, the refrigerator 100 displays an operating sound setting screen including an operating sound list that indicates an operating sound output condition on which the operating sound may be generated and a sound list that indicates stored sounds on the display unit 130, and the user selects one from among the sounds displayed in the sound list of the operating sound setting screen and allows the selected sound to be mapped to the operating sound list of the operating sound setting screen.
FIGS. 7A and 7B are views illustrating operating sound setting screens of the refrigerator 100 including the sound module 10 of FIG. 1.
If an operating sound setting instruction is input from the user, the TSPs 120 and 130 display an operating sound setting screen 121.
In detail, an operating sound list display region 121a in which the refrigerator 100 displays a time when or an event in which an operating sound is output, may be disposed at the left side of the operating sound setting screen 121. For example, the operating sound list display region 121a displays the case that the user opens or closes a door, the case that the user changes the target temperature of the refrigerator compartment or the freezer compartment, the case that the user takes water from the dispenser disposed in the refrigerator 100, the case that the refrigerator 100 malfunctions, the case that the ice-making device operates, or the case that the compressor 119 operates.
Also, a sound display region 121b is disposed at the right side of the operating sound setting screen 121 and displays sounds stored in the storage unit 160 of the refrigerator 100. That is, the refrigerator 100 displays various sounds that have been input through the TSPs 120 and 130, the communication unit 170, and the sound input unit 180 and stored in the storage unit 160, in the sound display region 121b. 
The user may select one from among various sounds displayed in the sound display region 121b and may allow the selected sound to be mapped to the operating sound list displayed in the operating sound list display region 121a, thereby setting an operating sound. For example, in case that doors 113a and 113b of the refrigerator 100 are opened for a long time, the user may select a voice “Doors of the refrigerator are opened” or a song such as “Close the Door” as an operating sound, in case that temperatures of storage compartments 121 and 122 exceed a reference temperature, the user may select a voice “The refrigerator is not operating normally. Please call a near service center.” as an operating sound, and in case that the setting temperature of the refrigerator is changed, the user may select a voice “Refrigeration temperature has been changed” as an operating sound.
In detail, as illustrated in FIG. 7A, the user may select one from among a plurality of sounds displayed in the sound display region 121b and may drag and drop the selected sound on one from among operating sound output conditions displayed in the operating sound list display region 121a, thereby setting the operating sound. Alternatively, as illustrated in FIG. 7B, the user may select one from among operating sound lists displayed in the operating sound list display region 121a and may select one from among sound lists displayed in the sound display region 121b, thereby setting the operating sound. Once the setting of the operating sound has been performed, the user may either select the confirm icon 137 or the cancel icon 139 to either confirm or to cancel, respectively, to confirm the setting the operating sound.
