Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0040] The sound control device of the embodiments of the utility model is described below with reference to the drawings.

[0041] As Figures 1-9 shown, the sound control device of the embodiments of the utility model comprises a main body 100, a signal receiving assembly 200 and a driving assembly 300.

[0042] Among them, the sound control device of the embodiment is a household appliance, when the user uses it in daily life, the sound control device of the embodiment can receive the voice instruction of the user through the signal receiving assembly 200 and / or the driving assembly 300, that is, the user is the sound source 400, and the voice instruction issued by the user is the sound wave 410 signal. The sound control device of the embodiment can respond to the voice instruction of the user, and operate in the corresponding working state according to the voice instruction, so as to realize the voice interaction between the user and the sound control device of the embodiment.

[0043] For example, the sound control device is an air conditioner, and the main body 100 is its indoor unit. When the user needs to adjust the indoor humidity through the air conditioner, the user can issue a voice instruction of dehumidification, and the air conditioner responds to the voice instruction and adjusts the air conditioner indoor unit to the working state of dehumidification.

[0044] For another example, the sound control device is a washing machine, and when the user needs to rinse the clothes in the washing machine, the user can issue a voice instruction of rinsing, and the washing machine responds to the voice instruction and adjusts its working state to the working state of the washing machine.

[0045] The signal receiving assembly 200 comprises a sound wave 410 receiver 210 and a cover 220, the cover 220 has a reflecting surface 221, the cover 220 is covered on the sound wave 410 receiver 210, and the cover 220 is configured so that the reflecting surface 221 can promote the sound wave 410 reflected thereby to enter the sound wave 410 receiver 210. The cover 220 is movably arranged on the main body 100, so that the orientation of the reflecting surface 221 can be adjusted.

[0046] That is, when the sound wave 410 signal emitted by the external sound source 400 is conducted to the reflecting surface 221 of the cover 220, the reflecting surface 221 can reflect the sound wave 410 signal and converge at the sound wave 410 receiver 210, so that more sound wave 410 signals are transmitted into the sound wave 410 receiver 210, thereby enhancing the sound pressure effect, improving the signal-to-noise ratio of the sound wave 410 signal, and facilitating the intelligibility and auditory perception quality of the sound wave 410 signal.

[0047] The driving assembly 300 is connected with the cover 220, and the driving assembly 300 is configured to receive the external sound source 400 and drive the reflecting surface 221 to face the position of the external sound source 400 according to the external sound source 400. After receiving the sound wave 410 signal, the driving assembly 300 can determine the position of the sound source 400 emitting the sound wave 410 signal according to the sound wave 410 signal, and adjust the cover 220 to the position where the reflecting surface 221 faces the sound source 400, so that the cover 220 converges more sound wave 410 signals at the sound wave 410 receiver 210.

[0048] When the user interacts with the sound control device of the embodiment, the user emits a voice instruction, and the driving assembly 300 receives the voice instruction and determines the position of the user. The driving assembly 300 adjusts the cover 220 to the position where the reflecting surface 221 faces the user.

[0049] For example, the sound control device is an air conditioner, and when the user needs to adjust the air conditioner to a cooling mode of 27 degrees, the user first emits a first voice instruction to adjust the cover 220 to the position where the reflecting surface 221 faces the user. The user then emits a second voice instruction to adjust the temperature to 27 degrees, so that the air conditioner is accurately adjusted to 27 degrees.

[0050] Compared with the related art, the sound control device of the embodiment can first determine the position of the sound source 400 by the driving assembly 300, adjust the cover 220 to the position where the reflecting surface 221 faces the sound source 400, and converge the sound wave 410 signal conducted to the reflecting surface 221 of the cover 220 at the sound wave 410 receiver 210, thereby enhancing the sound pressure effect, improving the signal-to-noise ratio of the sound wave 410 signal, and facilitating the intelligibility and auditory perception quality of the sound wave 410 signal, so that the interaction success rate of the user voice interaction is improved.

[0051] In order to make the application easier to be understood, the sound control device of the embodiment is further described below by taking the first axis consistent with the up-down direction as an example and taking the second axis consistent with the left-right direction as an example. The first axis is perpendicular to the second axis.

[0052] In some embodiments, as Figure 3As shown, the reflecting surface 221 is a rotationally symmetrical concave parabolic surface, and the sound wave 410 receiver 210 is arranged at the focal point of the concave parabolic surface, so that the sound wave 410 receiver 210 receives the sound wave 410 reflected by the reflecting surface 221.

[0053] That is, the concave parabolic surface can reflect the sound wave 410 incident on the reflecting surface 221 thereof along a direction parallel to the central axis thereof to the focal point thereof. The sound wave 410 receiver 210 is located at the focal point of the concave parabolic surface, and the sound wave 410 reflected by the reflecting surface 221 can converge on the sound wave 410 receiver 210, thereby enhancing the sound pressure effect and improving the signal-to-noise ratio, thus being beneficial to enhancing the intelligibility and auditory perceptual quality of the voice signal.

[0054] In some embodiments, as shown, Figure 8 The driving assembly 300 further includes a receiving module 310, an executing module 320, and a control module 330.

[0055] The receiving module 310 is configured to receive the sound source 400 signal, and the executing module 320 is connected to the signal receiving assembly 200. The control module 330 is connected to the executing module 320 and the receiving module 310, and is configured to control the executing module 320 to adjust the orientation of the reflecting surface 221 according to the sound source 400 signal.

[0056] When the user controls the sound control device by voice, the user issues a voice instruction, the receiving module 310 receives the sound wave 410 signal contained in the voice instruction, and the control module 330 determines the user's location according to the sound wave 410 signal. The control module 330 then controls the executing module 320 to make the reflecting surface 221 of the cover body 220 face the user, so that the reflecting surface 221 can better receive the sound wave 410 signal.

[0057] When the user controls the smart device by voice in a certain working mode, the voice instruction contained is relatively complex. For example, the sound control device is an air conditioner, and the user will issue instructions for adjusting the temperature and adjusting the air conditioner to a dehumidifying mode, a ventilation mode, etc. during use, and the sound wave 410 signal is relatively complex.

[0058] In some alternative embodiments, in order to better and more accurately analyze and execute the voice instruction of the user, when using the sound control device of the present embodiment, the user can first issue a relatively simple instruction for detecting the actual position of the user, so that the sound control device first determines the location of the user, so that the reflecting surface 221 of the cover body 220 faces the user. The user then issues a voice instruction to the sound control device containing the actual demand thereof.

[0059] For example, the voice control device is an air conditioner, and a user needs to adjust the room temperature to 27 degrees. The user now gives a voice command such as "wake up" or "position", so that the reflecting surface 221 of the cover 220 faces the user. The user then gives a voice command containing the temperature adjustment to 27 degrees.

[0060] In some embodiments, the receiving module 310 is the sound wave 410 receiver 210. That is, the sound wave 410 receiver 210 also serves as the receiving module 310 that receives the sound wave 410 signal used to locate the position of the sound source 400, so that there is no need to additionally set other sound wave 410 receiving devices, reducing structural redundancy and greatly reducing the manufacturing cost of the voice control device of the present embodiment.

[0061] In some embodiments, the control module 330 includes a processor, a memory, a communication interface, and a communication bus, and the processor, the memory, and the communication interface complete mutual communication through the communication bus. The processor is used to provide computing and control capabilities.

[0062] The memory includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and computer program instructions. The internal memory provides an environment for the operating system and computer program instructions in the non-volatile storage medium to run.

[0063] The communication interface of the above device is used for wired or wireless communication with an external terminal. The wireless communication can be achieved through WIFI, an operator network, NFC (Near Field Communication), or other technologies. The control module 330 provided in the present embodiment has a memory for storing computer program instructions, and the computer program instructions can implement the plurality of embodiments of the control method of the air conditioner when executed by the processor.

[0064] Those skilled in the art can understand that all or part of the process of receiving a user voice signal and completing corresponding control work in the above-mentioned embodiments of the voice control device can be instructed by computer program instructions to relevant hardware, and the computer program instructions can be stored in a non-volatile computer readable storage medium.

[0065] In some embodiments, as shown in Figures 1-4 The execution module 320 includes a support 321, a first driver 324, and a second driver 325.

[0066] The support 321 includes a seat body 322 and a frame body 323. The seat body 322 is arranged on the main body 100, and the frame body 323 is rotatably arranged on the seat body 322 about a first axis. The cover 220 is rotatably arranged on the frame body 323 about a second axis.

[0067] The first driver 324 is connected with the frame body 323 and the control module 330, so that the first driver 324 drives the frame body 323 to rotate around the first axis. The second driver 325 is connected with the cover body 220 and the control module 330, so that the first driver 324 drives the cover body 220 to rotate around the second axis.

[0068] That is, the orientation of the reflecting surface 221 of the cover body 220 in the transverse direction is changed by rotating the frame body 323 relative to the seat body 322, and the orientation of the reflecting surface 221 of the cover body 220 in the vertical direction is changed by rotating the cover body 220 relative to the frame body 323. Then, the orientation of the reflecting surface 221 of the cover body 220 is adjusted in a large range by rotating the frame body 323 relative to the seat body 322 by the first driver 324 and rotating the cover body 220 relative to the frame body 323 by the second driver 325, respectively. In addition, the structure is simple and easy to manufacture.

[0069] Optionally, the first driver 324 and the second driver 325 can be driving motors.

[0070] In some embodiments, as shown in Figure 2 The shell 110 defines a receiving cavity 120, and the signal receiving assembly 200 and the driving assembly 300 are arranged in the receiving cavity 120. On the one hand, the signal receiving assembly 200 and the driving assembly 300 are arranged in the receiving cavity 120, and the shell 110 can visually shield the signal receiving assembly 200 and the driving assembly 300, thereby improving the integrity of the sound control device and improving the user experience. On the other hand, the shell 110 can protect the signal receiving assembly 200 and the driving assembly 300, thereby avoiding damage to the signal receiving assembly 200 and the driving assembly 300 during transportation, installation, and other operations of the sound control device.

[0071] In some embodiments, as shown in Figure 5 A plurality of first through holes 111 are arranged on the shell 110, each first through hole 111 is in communication with the receiving cavity 120, and the plurality of first through holes 111 correspond to the signal receiving assembly 200. That is, a plurality of first through holes 111 are arranged on the shell 110 and are in communication with the receiving cavity 120, so that the sound wave 410 signal from the outside is more easily transmitted into the signal receiving assembly 200 arranged in the receiving cavity 120.

[0072] Specifically, the plurality of first through holes 111 are arranged in a rectangular array on the shell 110, and the sound inlet structure formed by the plurality of first through holes 111 corresponds to the signal receiving assembly 200. After the cover body 220 adjusts the orientation of the reflecting surface 221, a part of the plurality of first through holes 111 can correspond to the signal receiving assembly 200, so that the sound wave 410 signal from the outside is transmitted into the signal receiving assembly 200.

[0073] In some embodiments, as shown in Figures 6-7 The shell 110 is provided with a second through hole 112. The main body 100 further comprises a flexible shielding sheet 130 connected to the second through hole 112. The flexible shielding sheet 130 is provided with a third through hole 131, and the edge 222 of the reflecting surface 221 is connected to the wall surface of the third through hole 131, and the reflecting surface 221 faces the outside.

[0074] That is, the outer edge 222 of the cover 220 cooperates with the flexible shielding sheet 130 through the third through hole 131, so that the reflecting surface 221 and the sound wave 410 receiver 210 are both located outside, and the other part of the signal receiving assembly 200 and the driving assembly 300 are both spaced apart from the outside through the flexible shielding sheet 130, so that the shell 110 and the flexible shielding sheet 130 cover the other part of the signal receiving assembly 200 and the driving assembly 300, thereby improving the sound receiving effect of the sound wave 410 receiver 210 and the overall performance of the sound control device. And because the flexible shielding sheet 130 is made of soft material, the flexible shielding sheet 130 will not affect the movement of the cover 220, improving the practicability.

[0075] Specifically, the second through hole 112 is formed with an annular stepped portion, which includes an annular kick surface 113 and an annular tread surface 114, the annular kick surface 113 is located outside the annular tread surface 114, the outer edge 222 of the annular kick surface 113 is connected to the outer surface of the shell 110, and the inner edge 222 of the annular kick surface 113 is connected to the annular tread surface 114. When the cover 220 moves, the flexible shielding sheet 130 will be pulled by the external force of the cover 220, and the annular stepped portion supports the flexible shielding sheet 130 to ensure the stability of the installation of the flexible shielding sheet 130.

[0076] Optionally, the material of the flexible shielding sheet 130 is rubber material; or the material of the flexible shielding sheet 130 is woven fabric; or the material of the flexible shielding sheet 130 is other soft material.

[0077] In some optional embodiments, the annular stepped portion is continuous and integral in the circumferential direction of the second through hole 112.

[0078] In other optional embodiments, the annular stepped portion is a plurality of parts spaced apart in the circumferential direction of the second through hole 112, that is, the annular stepped portion includes a plurality of parts, and the plurality of parts are arranged spaced apart in the circumferential direction of the second through hole 112.

[0079] Part of the flexible shielding sheet 130 is connected with the annular tread 114 and the annular kick 113, and the outer surface of the part of the flexible shielding sheet 130 is flush with the outer edge 222 of the annular kick 113, so as to improve the integrity of the flexible shielding sheet 130 and the shell 110 in appearance, and improve the user experience.

[0080] In some embodiments, the sound control device is one of an air conditioner and a washing machine. That is, the sound control device is an air conditioner; or, the sound control device is a washing machine.

[0081] In some alternative embodiments, the sound control device is an air conditioner hanging machine, and the signal receiving assembly 200 is arranged at the bottom of the air conditioner hanging machine. When the air conditioner hanging machine is used, the air conditioner hanging machine is installed on the wall part at a high position in the room, and the signal receiving assembly 200 arranged at the bottom of the air conditioner hanging machine facilitates the sound wave 410 receiver 210 to receive the sound wave 410 signal.

[0082] In some alternative embodiments, the sound control device is an air conditioner hanging machine, and the signal receiving assembly 200 is arranged at the bottom of the air conditioner hanging machine. When the air conditioner hanging machine is used, the air conditioner hanging machine is installed on the wall part at a high position in the room, and the signal receiving assembly 200 arranged at the bottom of the air conditioner hanging machine facilitates the sound wave 410 receiver 210 to receive the sound wave 410 signal.
