For TVs with far-field voice functions, the sound pickup module used to receive business signals generally has both remote control and on / off button functions.

[0003] As the frame of a television set becomes narrower and thinner, the internal space thereof becomes smaller and smaller. Therefore, existing television sets tend to move the far-field sound pickup housing to the outside of the television set body to meet the requirements of existing narrow and thin frame designs.

[0004] In the related art, the far-field sound pickup housing is set at the bottom of the TV or separately set outside the TV. The sound pickup board is set in the sound pickup housing, and the sound pickup housing has a corresponding mic pickup hole. The sound is transmitted to the pickup on the sound pickup board through the mic pickup hole, thereby realizing remote voice interaction. However, in actual use, sound waves can also be transmitted from other positions of the sound pickup housing to the pickup on the sound pickup board, thereby causing interference, affecting the recognition of sound, and affecting the far-field interaction function.

[0074] Figure 8 It is a structural schematic diagram of the sound pickup plate 300 of the utility model. Fig. 9 It is a front view of the far-field sound pickup structure 20 of the present invention. Fig.10 yes Fig. 9 Cross-section view at the middle BB.

[0075] See also Figures 2 to 10 In this embodiment, the far-field sound pickup structure 20 may further include a sound pickup plate 300, which is accommodated in the accommodating cavity of the housing 200; a sound pickup 310 is disposed on the front side of the sound pickup plate 300; the sound pickup 310 faces the mic sound pickup hole 211 on the housing 200, so that sound waves can pass through the mic sound pickup hole 211 and be transmitted to the sound pickup 310. The sound pickup plate 300 is electrically connected to the display body 10, so that the far-field sound pickup structure 20 is electrically connected to the display body 10.

[0076] The command information sent by the user is transmitted to the microphone 310 on the pickup board 300 through the mic pickup hole 211 in the form of sound waves. The microphone 310 receives the corresponding sound wave information and converts the sound wave information into an electrical signal. After transmitting the electrical signal to the display body 10, the display body 10 executes the corresponding command.

[0077] One or more pickups 310 are disposed on the pickup plate 300 , and the number and positions of the pickups 310 correspond one-to-one to the number and positions of the mic pickup holes 211 .

[0078] In the related art, the sound waves emitted by the user can be transmitted to the microphone 310 through the mic pickup hole 211. The sound waves emitted by the user can also be transmitted to the microphone 310 through structures such as the housing 200. Sound waves on different paths or other sound waves transmitted from other paths will interfere with the microphone 310 and affect the voice interaction of the far-field voice structure.

[0079] The pickup plate 300 is limited in the mounting cavity 221 of the rear housing 220. A protruding limiting rib 223 is formed in the mounting cavity 221. A limiting hole 320 is provided on the periphery of the pickup plate 300. The limiting rib 223 is engaged in the limiting hole 320 to limit the pickup plate 300.

[0081] The rear side of the pickup plate 300 abuts against the support ribs 224. The support of the pickup plate 300 by the multiple support ribs 224 arranged at intervals effectively ensures the stability of the support of the pickup plate 300. The arrangement of the support ribs 224 can also enhance the structural strength of the rear shell 220.

[0082] Fig.11 It is a schematic diagram of the matching of the sound-absorbing cotton of the utility model on the front shell.

[0083] See also Figures 2 to 11 In this embodiment, the far-field voice structure can include a sound-absorbing cotton 400, the sound-absorbing cotton 400 has a ring structure, and the periphery of the sound-absorbing cotton 400 is a polygonal, circular or elliptical structure. In this embodiment, the sound-absorbing cotton 400 is a rectangular structure around the periphery.

[0084] The sound-absorbing cotton 400 is located between the front side wall of the housing 200 and the front side of the pickup plate 300.

The front and rear sides of the sound-absorbing cotton 400 are respectively sealed and attached to the front side of the housing 200 and the front side wall of the housing 200, so that the sound waves can only be transmitted to the pickup 310 through the mic pickup hole 211. The sound waves are blocked from being transmitted to the pickup 310 through other paths.

[0085] The sound-absorbing cotton 400 can be elastically deformed, and the front side and rear side of the sound-absorbing cotton 400 are both planar structures, and the front and rear sides of the sound-absorbing cotton 400 are elastically pressed against the front side of the shell 200 and the front side wall of the shell 200, respectively. The elastic pressing can ensure the sealing of the two sides of the sound-absorbing cotton 400 connected to the sound pickup plate 300 and the shell 200, respectively.

[0086] In this embodiment, the front side of the sound-absorbing cotton 400 extends into and fits into the limiting groove 212, and the limiting groove 212 is used for the installation and positioning of the sound-absorbing cotton 400, which facilitates the installation of the sound-absorbing cotton 400 and can also change the position of the sound-absorbing cotton 400.

[0087] The front wall of the limiting groove 212 is a plane, and the front end of the sound-absorbing cotton 400 is a plane structure to ensure the sealing of the connection between the sound-absorbing cotton 400 and the shell 200, and effectively prevent the sound waves from being transmitted from the shell 200 to the pickup 310.

[0088] In this embodiment, the sound-absorbing cotton 400 is a circumferential rectangular structure, and the limiting groove 212 is correspondingly configured as a circumferential rectangular structure. In some embodiments, the sound-absorbing cotton 400 is a circumferential circular structure, and the limiting groove 212 is correspondingly configured as a circumferential circular structure.

[0089] One end of the sound-absorbing cotton 400 in the front-to-back direction can be pasted on the corresponding structure, and the other end can be sealed and fitted to the corresponding structure.

[0090] Referring to Figures 2 to 3 again, the far-field sound pickup structure 20 can also include an elastic flexible pad 500, which is disposed in the mounting cavity 221 of the housing 200. The flexible pad 500 is clamped between the rear side of the pickup plate 300 and the rear side wall of the mounting cavity 221. The flexible pad 500 can press the pickup plate 300 forward to keep the pickup plate 300 pressed against the sound-absorbing cotton 400, thereby ensuring the sealing of the connection of the sound-absorbing cotton 400.

[0091] A protruding abutting rib 225 is formed on the rear side of the installation cavity 221 , and the abutting rib 225 abuts against the rear side of the flexible pad 500 .

[0092] In the utility model, the microphone 310 on the pickup plate 300 is opposite to the mic pickup hole 211, and the sound-absorbing cotton 400 is a ring structure; the sound-absorbing cotton 400 is located between the front side wall of the shell 200 and the front side of the sound pickup plate 300, and the front and rear sides of the sound-absorbing cotton 400 are sealed and adhered to the front side of the shell 200 and the front side wall of the shell 200 respectively; the sound-absorbing cotton 400 surrounds the mic pickup hole 211 and the microphone 310, so that the sound waves can only propagate from the mic pickup hole 211 to the microphone 310, and the sound waves cannot be transmitted to the microphone 310 through other paths, effectively ensuring that the sound waves are transmitted from the mic pickup hole 211 to the microphone 310, effectively avoiding the interference of sound waves in other positions on the sound pickup effect, and improving the accuracy and effect of far-field interaction.
