Embodiment

Below in conjunction with drawings and embodiments, the utility model is described in further detail.

Fig. 1-2 is referred to, the utility model provides a kind of microphone device 100, including lower cover 1, upper cover plate 2, sounding list Body 3 and FPC 4.

The upper cover plate 2 is covered on the lower cover 1 and surrounds receiving space (non-label) jointly.

The sounding monomer 3 is contained in the receiving space, for sounding.In present embodiment, the sounding monomer 3 It is fixed on the upper cover plate 2.

The FPC 4 is fixedly connected with the sounding monomer 3；The FPC 4 is used to draw the voice coil loudspeaker voice coil of the sounding monomer 3 Line (not shown) is led to outside the receiving space, on the one hand prevents the voice coil leads to be broken, on the other hand convenient and outside Power supply connection (not shown), and the electric connection structure stability formed is good.

Incorporated by reference to shown in Fig. 3, in present embodiment, specifically, the FPC 4 includes wire connections 41, drawn by described Line connecting portion 41 extend extension 42, from the extension 42 to the direction of lower cover 1 bend extension kink 43 with And by the horizontally extending junction 44 for being used to connect external power source of the kink 43.

The wire connections 41, which are located in the receiving space and fix to be formed with the sounding monomer 3, to be electrically connected.

Specifically, the wire connections 41 include positive terminal 411, born with what the spacer insulator of positive terminal 411 was set Extreme 412 and the insulating segment 413 of the connection positive terminal 411 and the negative pole end 412.The extension 42 is by the positive terminal 411 or described negative pole ends 412 extend.Certainly, the extension 42 can also be extended by the insulating segment 413, and this is also feasible.

The extension 42, which abuts, to be supported in the upper cover plate 2 and extends to outside the receiving space and cause the bending Portion 43 and the junction 44 are located at outside the receiving space.

In present embodiment, the extension 42 is also included through the first positioning hole 421 set thereon, the upper cover plate The side of the 2 close lower cover 1 is provided with the first locating dowel 21 coordinated with first positioning hole 421, and described first is fixed Position hole 421 is arranged in first locating dowel 21.The structural strengthening FPC 4 and the upper cover plate 2 fixation fastness, are carried The high stability of the microphone device 100.

Direction extension of the kink 43 from the extension to the lower cover 1, for realizing the junction 44 It is bonded with the abutting of the lower cover 1.Kink 43 is located at outside receiving space.

The junction 44 abuts and fits in the lower cover 1, because the junction 44 is located at outside the receiving space When side, the lower cover 1 and the upper cover plate 2 are through ultrasonic bonding, the two does not make to the junction 44 and kink 43 Into influence, hence in so that phenomenon of rupture can't occur because of ultrasonic bonding for whole FPC, the microphone device 100 is improved Yield rate.Meanwhile also just because of the upper cover plate 2 and the lower cover 1 do not cause to the junction 44 and kink 43 Influence so that when the junction 44 extends abutting by the kink 43 and fits in the lower cover 1, the one of its fitting Cause property is good, and reliability is excellent.

In present embodiment, the junction 44 is also included through the second positioning hole 441 set thereon, the lower cover The side of the 1 close upper cover plate 2 is provided with the second locating dowel (not shown) coordinated with second positioning hole 441, described Second positioning hole 441 is arranged in second locating dowel.The setting of the structure adds the FPC 4 and the lower cover 1 Fixing intensity, equally also improve the stabilizability of the microphone device 100.

More excellent, in present embodiment, the wire connections 41 and the junction 44 are different positioned at two respectively Plane and arranged in parallel, certainly, the structure and position relationship of the two are not limited to this.

Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in Other related technical fields, are similarly included in scope of patent protection of the present utility model.
