Many ins and outs.But, even if there is no these ins and outs and kind based on following embodiment
Plant and change and modifications, it is also possible to realize the application each claim technical scheme required for protection.
First embodiment of the present utility model relates to a kind of mike, as shown in Figure 1.Mike comprises
Upper cover body 11, it is incorporated into lower cover 12, the first insulating part (not shown) of upper cover body 11 and comprises
Positive wire and the audio-frequency assembly of negative wire.Wherein, upper cover body 11 is provided with the hole 112 run through.Just
One of them of pole lead-in wire and negative wire is connected to the inner surface of upper cover body 11, and another is connected to lower cover
The inner surface of body 12.In present embodiment, positive wire is connected to the inner surface of upper cover body 11, negative pole
Lead-in wire is connected to the inner surface of lower cover 12.
The upper side wall 111 that upper cover body 11 has a upper diapire and the edge by upper diapire extends out, hole
The 112 upper diapires being arranged at upper cover body 11, lower cover 12 has lower diapire and the edge by lower diapire
The lower wall 121 extended out.Wherein, upper side wall 111 and lower wall 121 form upper cover body and lower cover
The joint portion of body, as shown in Fig. 2 a to Fig. 2 c.First insulating part 3 is arranged on upper cover body 11 and lower cover
The joint portion of body 12 is with upper cover body 11 and the lower cover 12 of being electrically insulated, and makes upper cover body 11, lower cover
Confined space is formed between 12.
First insulating part 3 could be arranged to be held between upper side wall 111 and lower wall 121, upper side wall
111 are incorporated into the first insulating part 3 by mucigel respectively with lower wall 121；Or the first insulating part 3
Ejection formation is in one of them of upper side wall 111 and lower wall 121, upper side wall 111 and lower wall 121
Other in which be incorporated into the first insulating part 3 by mucigel.
Audio-frequency assembly comprises: the film ring 13 that stretches tight, insulation spacer 14, back pole plate 15, metal connect ring 16 with
And it is provided with the circuit board module 17 of positive wire and negative wire.Wherein, back pole plate 15 also comprises backplane
