Embodiment 1

[0025] like Figure 1 to Figure 3 As shown, the microphone channel structure provided by Embodiment 1 of the present application includes: a middle frame 10 and a sealing member 20 .

[0026] like figure 1 As shown, the middle frame 10 is provided with a front sound cavity channel 11 , a middle sound cavity channel 12 and a rear sound cavity channel 13 .

[0027] like figure 1 and Figure 8 As shown, the front sound chamber channel 11 is used to communicate with the microphone 203 .

[0028] like figure 1 As shown, the rear sound cavity channel 13 extends to the outer surface of the middle frame 10 .

[0029] like figure 1 As shown, the front cavity channel 11 , the middle cavity channel 12 and the rear cavity channel 13 are sequentially connected to form the sound channel 100 .

[0030] like figure 1 As shown, the middle frame 10 is provided with a sound groove 121 , the sealing member 20 seals the opening of the sound groove 121 , and the sealing member 20 and the so...

Embodiment 2

[0055] like Figure 4 and Figure 5 As shown, the microphone channel structure provided by embodiment 2 of the present application is substantially the same as the microphone channel structure provided by embodiment 1, the difference mainly being that the sound groove 121 includes a first groove 122 and a groove bottom arranged on the first groove 122 The second slot 123. The sealing member 20 is arranged at the bottom of the first groove 122 and seals the opening of the second groove 123 , and the sealing member 20 and the second groove 123 form the channel 12 of the midrange cavity.

[0056] In the microphone channel structure provided by the present application, the first groove 122 plays a positioning role, which facilitates the sealing member 20 to quickly fit into the first groove 122, and seals the opening of the second groove 123 to form the alto cavity channel 12. The first groove 122 The setting improves the assembly efficiency of the sealing member 20 .

[0057] ...

Embodiment 3

[0059] like Figure 6 As shown, the microphone channel structure provided by Embodiment 3 of the present application includes: a middle frame 10 .

[0060] The middle frame 10 is provided with a front sound cavity channel 11 , a middle sound cavity channel 12 and a rear sound cavity channel 13 . The front sound cavity channel 11 is used to communicate with the microphone 203 . The rear sound chamber channel 13 extends to the outer surface of the middle frame 10 . The front sound cavity channel 11 , the middle sound cavity channel 12 and the rear sound cavity channel 13 are sequentially connected to form the sound channel 100 .

[0061] In the microphone channel structure provided by the present application, the front sound cavity channel 11, the middle sound cavity channel 12 and the rear sound cavity channel 13 form a curved sound channel 100, which ensures the quality of the sound through the sound channel 100. Channel 100 is shorter in length. In addition, the outlet of...

Abstract

The invention provides a microphone sound channel structure and electronic equipment. The microphone sound channel structure comprises a middle frame, wherein the middle frame is provided with a frontsound cavity channel, a middle sound cavity channel and a rear sound cavity channel; the front sound cavity channel is used for communicating with a microphone; the rear sound cavity channel extendsto the outer surface of the middle frame; the front sound cavity channel, the middle sound cavity channel and the rear sound cavity channel are sequentially communicated to form a sound channel. According to the microphone sound channel structure provided by the invention, the front sound cavity channel, the middle sound cavity channel and the rear sound cavity channel form the bent sound channel,and the length of the sound channel is ensured to be relatively short under the condition of ensuring the quality of sounds emitted from the sound channel; besides, outlets of the sound channel are formed in the side faces of the middle frame, the space of the outer surface of the middle frame is reasonably utilized, and the space utilization rate is increased; moreover, the sound channel is integrally formed on the middle frame, so that the use of other parts is reduced, the structure is simple, the production and manufacturing are easy, and the production and manufacturing cost of the product is reduced.

Description
