Description

Technical Field

[0001] This invention relates to the field of electronic equipment technology, specifically to a central control screen and an electronic device. Background Technology

[0002] In the field of smart homes, central control screens with microphones and speakers have become an important part of modern homes. They combine advanced voice recognition and artificial intelligence technologies to provide users with a more convenient home control experience.

[0003] Smart home control screens often include microphones and speakers. When the speaker plays sound, this sound can become background noise picked up by the microphone. If the background noise is too loud, it can mask the user's voice commands, making it difficult for the microphone to accurately recognize them. Therefore, when users try to input commands via voice control, the microphone's recognition rate may drop significantly.

[0004] Therefore, this application studies a central control screen that improves the microphone recognition rate. Utility Model Content

[0005] To improve the microphone recognition rate on the central control screen.

[0006] On the one hand, the central control screen provided in this application adopts the following technical solution:

[0007] A central control screen includes a housing, a PCB board, a microphone, a silicone component, and a speaker. The PCB board is mounted on one side of the housing, forming a receiving space between them. The microphone is mounted on the PCB board and located within the receiving space. The silicone component is mounted within the receiving space and covers the microphone. The microphone has a first sound recognition hole, and both the silicone component and the housing have a second sound recognition hole corresponding to the first sound recognition hole. The speaker is disposed within the housing, and the housing has a sound output hole corresponding to the speaker. The second sound recognition hole and the sound output hole face different directions.

[0008] By adopting the above technical solution, the periphery of the first sound recognition hole is wrapped and sealed with silicone parts, and the microphone is isolated from other parts inside the housing by the cooperation of the PCB board and the housing, separating the speaker and the microphone sound recognition hole, and preventing the speaker from transmitting sound from inside the structure to the microphone and affecting the microphone's recognition; and the speaker's sound outlet and the sound recognition hole are oriented differently, which better prevents the sound recognition hole from picking up the speaker's sound, so the microphone can be less affected by the speaker's sound, thereby improving the microphone's recognition rate.

[0009] Optionally, the microphone spacing is set to at least two.

[0010] Optionally, the housing is provided with abutting ribs along the periphery of its second sound recognition hole. When the silicone part is installed in the receiving space, the abutting ribs press against the silicone part in the direction of the microphone.

[0011] By adopting the above technical solution, the silicone parts can be better squeezed and fixed by the abutting ribs, so that the silicone parts can better wrap and seal the microphone and avoid external noise interference.

[0012] Optionally, the cross-section of the abutment rib has a triangular structure.

[0013] Optionally, the silicone part has a receiving cavity and a relief groove, and the microphone has a limiting plate. During installation, the microphone is placed in the receiving groove, the limiting plate abuts against the relief groove, and is connected to the PCB board.

[0014] By adopting the above technical solution, the silicone component can more fully cover the microphone.

[0015] Optionally, it also includes a screen cover plate, which is disposed on one side of the housing and has a second sound recognition hole corresponding to the first sound recognition hole.

[0016] Optionally, the diameters of the first sound recognition hole, the second sound recognition hole of the silicone, the second sound recognition hole of the housing, and the second sound recognition hole of the screen cover plate increase sequentially.

[0017] Optionally, the housing has a positioning post, and the silicone part has a positioning hole, during installation, the positioning post extends into the positioning hole.

[0018] On the other hand, this application also provides an electronic device that adopts the following technical solution:

[0019] An electronic device, including the aforementioned central control screen.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. The first sound recognition hole is wrapped and sealed with silicone parts, and the microphone is isolated from other parts inside the housing by the cooperation of the PCB board and the housing. This separates the speaker and the microphone sound recognition hole, preventing the speaker's sound from the inside of the structure from affecting the microphone's recognition. Furthermore, the speaker's sound outlet and the sound recognition hole face different directions, which better prevents the sound recognition hole from picking up the speaker's sound. Therefore, the microphone can be less affected by the speaker's sound, thereby improving the microphone's recognition rate.

[0022] 2. The abutment ribs can better compress and fix the silicone parts, thereby allowing the silicone parts to better wrap and seal the microphone and avoid interference from external noise. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0033] This application discloses a central control screen. (Refer to...) Figure 1 and Figure 2The central control screen includes a housing 1, a PCB board 2, a microphone 3, a silicone component 4, and a speaker 5. The PCB board 2 is installed on one side of the housing 1, forming an accommodating space 6. The microphone 3 is installed on the PCB board 2 and located within the accommodating space 6. The silicone component 4 is installed within the accommodating space 6 and covers the microphone 3. In this embodiment, the PCB board 2 is fixed to the housing 1 by bolts 7, and a bolt 7 is provided on both sides of the accommodating space 6 to evenly press the PCB board 2 towards one side of the housing 1, thereby covering the inner wall of the accommodating space 6 with the silicone component 4. After the outer periphery of the silicone component 4 is compressed, it wraps around the microphone 3, so that the periphery of the microphone 3 is sealed and isolated by the silicone component 4, preventing the speaker 5 from transmitting sound from inside the structure to the microphone 3, thus better preventing the microphone 3 from being interfered with by the sound of the speaker 5.

[0034] The microphone 3 has a first sound recognition hole 8. Both the silicone part 4 and the housing 1 have second sound recognition holes 9 corresponding to the first sound recognition hole 8. When a user inputs a command through voice control of the microphone 3, the voice enters the first sound recognition hole 8 through the second sound recognition hole 9, thus enabling the microphone 3 to pick up sound. The speaker 5 is located inside the housing 1, and the housing 1 has a sound outlet 10 corresponding to the speaker 5. The second sound recognition hole 9 and the sound outlet 10 face different directions. Figure 3 In this embodiment, the housing 1 is configured as a cube or cuboid. The sound outlet 10 of the speaker 5 is opened on the side of the housing 1, and the second sound recognition hole 9 is opened on the surface with the largest area of ​​the housing 1 and is located near the edge. The side of the speaker 5 sound outlet 10 and the side near the second sound recognition hole 9 are different sides. Therefore, when the speaker 5 emits sound, it can further avoid interference with the microphone 3's sound recognition.

[0035] Continue to refer to Figure 1 In some embodiments, at least two microphones 3 are spaced apart. In this embodiment, two microphones 3 are spaced apart along the length of the PCB board 2. In other embodiments, one or more microphones may be used as needed.

[0036] Reference Figure 2 and Figure 3 In some embodiments, the central control screen also includes a screen cover 11, which covers one side of the housing 1 and has a second sound recognition hole 9 corresponding to the first sound recognition hole 8. That is, the silicone part 4, the housing 1 and the second sound recognition hole 9 of the screen cover 11 are in corresponding positions and are interconnected with the first sound recognition hole 8.

[0037] Continue to refer to Figure 2In some embodiments, the apertures of the first sound recognition hole 8, the silicone second sound recognition hole 9, the housing 1 second sound recognition hole 9, and the screen cover 11 second sound recognition hole 9 increase sequentially, that is, the aperture of the first sound recognition hole 8 is the smallest, and the aperture of the screen cover 11 second sound recognition hole 9 is the largest. When the user inputs commands through the voice control microphone 3, the sound is gradually picked up along the screen cover 11 to the microphone 3, so that the microphone 3 can better recognize the voice.

[0038] Reference Figure 4 In some embodiments, the housing 1 is provided with abutment ribs 12 along the periphery of its second sound recognition hole 9. Figure 2 When the silicone part 4 is installed in the receiving space 6, the abutting rib 12 presses against the silicone part 4 towards the microphone 3. In some embodiments, the cross-section of the abutting rib 12 is approximately triangular, which allows for more stable pressure on the silicone part 4, so that the silicone part 4 stably covers the microphone 3.

[0039] Continue to refer to Figure 4 In some embodiments, the housing 1 has a positioning post 13 and the silicone part 4 has a positioning hole 14. During installation, the positioning post 13 extends into the positioning hole 14, so that the silicone part 4 can be better limited and fixed.

[0040] Reference Figure 5 In some embodiments, the silicone part 4 has a receiving cavity 15 and a relief groove 16. The receiving cavity 15 communicates with the second sound recognition hole 9. The microphone 3 has a limiting plate 17, which makes the cross-section of the microphone 3 have a "T" shape. During installation, the microphone 3 is placed in the receiving groove, and the limiting plate 17 abuts against the relief groove 16. The end face of the limiting plate 17 is on the same plane as the end face of the silicone part 4, and the limiting plate 17 is connected to the PCB board 2. The silicone part 4 on the periphery of the limiting plate 17 also abuts against the PCB board 2, so that the microphone 3 can be better sealed and isolated, and the sound inside the housing 1 can be avoided as much as possible.

[0041] The implementation principle of a central control screen in this application embodiment is as follows: the first sound recognition hole 8 is wrapped and sealed around by a silicone part 4, and the microphone 3 is isolated from other parts inside the housing 1 by the cooperation of the PCB board 2 and the housing 1, separating the speaker 5 and the sound recognition hole of the microphone 3, so as to prevent the speaker 5 from transmitting from inside the structure to the microphone 3 and affecting the recognition of the microphone 3; and the sound outlet 10 of the speaker 5 is oriented differently from the sound recognition hole, so as to better prevent the sound recognition hole from picking up the sound of the speaker 5. Therefore, the microphone 3 can reduce the influence of the sound of the speaker 5, thereby improving the recognition rate of the microphone 3.
