The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

Fig. 1 is a schematic structural diagram of a microphone assembly in an exemplary embodiment of the present disclosure. As shown in fig. 1, the microphone assembly 1 includes: a microphone body 11 and an integral sound transmission duct 12. The sound transmission duct 12 comprises a first port 121, a second port 122 communicating with the first port 121 and at least one flexible bend 123. The first port 121 is fitted to the sound pickup hole 22 of the electronic device 2, a sidewall enclosing the second port 122 is in sealing fit with the microphone body 11, and the second port 122 is communicated with the microphone body 11. Each flexible bend 123 includes a plurality of bending positions to form the sound transmission duct 12 into a structural shape adapted to an arbitrary assembly space.

By providing the microphone assembly 1 with the integrated sound transmission pipe 12 and by sealing and matching the side wall enclosing the second port 122 with the microphone main body 11, the overall structure and the sealing structure of the sound transmission pipe 12 are simplified, and the sealing performance of the microphone assembly 1 is improved. Wherein, the sound transmission pipeline 12 comprises at least one flexible bending part 123, so that the sound transmission pipeline 12 can form a structural shape adapted to any assembly space through various bending postures of the flexible bending part 123, and the convenience in forming the sound transmission pipeline 12 is improved. After the sound transmission pipeline 12 is formed, the sound transmission pipeline can be directly laid and fixed at a corresponding position in the electronic equipment 2, so that the assembly convenience of the sound transmission pipeline and the internal space of the electronic equipment 2 is improved.

In order to achieve the matching of the sound transmission duct 12 to different assembly spaces, the number and arrangement of the flexible bent portions 123 may be varied, and the following description is given for the case where the sound transmission duct 12 includes one or more flexible bent portions 123:

in an embodiment, the sound transmission duct 12 comprises one flexible bend 123, the flexible bend 123 forming at least a partial section of the sound transmission duct 12. For example, as shown in fig. 1, the flexible bending part 123 forms an integral section of the sound transmission pipe 12, that is, the whole sound transmission pipe 12 is formed by processing a flexible bendable material such as aluminum, copper, etc., so as to further increase the variety of shapes of the sound transmission pipe 12. For another example, the flexible bent portion 123 may be a section located at the middle portion of the sound transmission duct 12 so as to form a bending effect matching the assembling space at the middle portion of the sound transmission duct 12. Alternatively, the flexible bending part 123 may be a section located at both ends of the sound transmission pipe 12, which is set according to a specific application scenario, and the disclosure is not limited thereto.

In another embodiment, as shown in fig. 2, the sound transmission duct 12 comprises a plurality of flexible bends 123, the plurality of flexible bends 123 being spaced apart at different sections of the sound transmission duct 12.

When the flexible bending portion 123 forms an integral section of the sound transmission pipe 12, the whole sound transmission pipe 12 may be a pipe formed by machining thin-walled bendable material such as aluminum, copper, rigid plastic, etc. Alternatively, when the sound transmission pipe 12 includes a plurality of flexible bends 123 arranged at intervals or the flexible bends 123 form a partial section of the sound transmission pipe 12, the flexible bends 123 may be bendable structures thinner than other positions of the sound transmission pipe 12, and the other positions except the flexible bends 123 are non-bendable structures thicker.

As shown in fig. 3, the sound transmission duct 12 is a circular tube having an internal channel 124 with a cross-sectional diameter of 1mm, and the flexible bending portion 123 can be bent into a suitable shape by cutting after the sound transmission duct 12 is fed. Alternatively, the sound transmission duct 12 may also be formed as a tube having an oval or irregular shape in cross-section of the internal passage 124, and the present disclosure is not limited to this in terms of the shape and size of the cross-section of the internal passage 124 and the outer wall 125 of the sound transmission duct 12. In addition, the inner wall of the channel of the sound transmission pipeline 12 forms a smooth curved surface, so that the acoustic turbulence for sound transmission is reduced, and the sound transmission quality is improved.

The coupling cover 113 is directly formed at the second port 122, so that not only can the assembling steps of the coupling cover 113 be reduced, but also the sealing performance of the fixed end of the coupling cover 113 in matching with the second port 122 can be improved, so that the microphone assembly 1 only needs to arrange the sealing member 114 at the matching position of the open end of the coupling cover 113 and the sound transmitting opening 1121 of the circuit board 112 in integral sealing, and the integral sealing performance and the sealing cost of the microphone assembly 1 are improved.
