【Embodiment】

The technical scheme in the embodiment of the utility model will be clearly and completely described below, it is clear that described Embodiment is only part of the embodiment of the present utility model, rather than whole embodiments.Based on the implementation in the utility model Example, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is belonged to The scope of the utility model protection.

Embodiment 1

Referring to figs. 1 to Fig. 3, the utility model provides a kind of microphone device 100, and the microphone device 100 includes the He of frame 11 Vibrational system in frame 11, magnetic circuit system are contained in, and the microphone device 100 is also included before being assembled with frame 11 Lid.

Microphone device 100 also include be fixed on frame 11 the first pad 5 and the second pad 6 and respectively with the first pad 5 and second pad 6 the first pin 7 and the second pin 8 that assemble, the first pad 5 and the second pad 6 are fixed on frame at interval 11 two corners, the first pad 5 and the second pad 6 assemble with the first pin 7 and the second pin 8 respectively, so that vibrational system Voice coil loudspeaker voice coil electrically connected with external circuitry.

Specifically, the rectangular shaped of frame 11, the first pad 5 and the second pad 6 are fixed on frame 11 in symmetrical structure Two corners of one side.Correspondingly, the first pin 7 and the second pin 8 respectively with the first pad 5 and the second pad 6 is corresponding sets Put, the first pad 5 and the second pad 6 are contained in the first accepting groove 15 and the second accepting groove 16 of frame 11.Further, One pin 7 and the second pin 8 are welded on the first pad 5 and the second pad 6 of frame 11 by surface mount process.

First pin 7 is identical with the structure of second pin 8, and by taking the first pin 7 as an example, reference picture 3, first inserts Pin 7 is including being fixed on the fixed part 70 of the first pad 5, self-fixed department 70 bends the elastic portion 71 of extension, own elasticity portion 71 extends Contact site 72, from contact site 72 to the hook portion 73 close to the bending extension of the side of elastic portion 71 and the one end of self-fixed department 70 to remote The clamping part 74 extended from the direction of elastic portion 71, hook portion 73 are hooked on clamping part 74, and fixed part 70 is used as and the first pad 5 Carry out surface-pasted pin pad.Further, the area of the fixed part 70 of the first pin 7 is 2mm²-4mm², it is preferably 2mm²-3mm².In addition, contact site 72 is provided with the contact point 721 with contact outside electronics, electric signal is outside by contact site 72 Boundary's circuit communication, for example, when microphone device 100 and client are assembled by the contact site of the first pin 7 and the second pin 8 with Detect circuit electrical connection.Second pin 8 is identical with the first pin 7, therefore eliminates the explanation to the second pin 8.

The utility model practicality surface mount process replaces laser spot welding, specifically, by surface mount process by first The pin 8 of pin 7 and second is welded on the first pad 5 and the second pad 6 of frame 11, accordingly, with respect to laser spot welding pad, Space-consuming is saved, so as to reserve more monomer inner spaces to accommodate bigger magnetic circuit, reaches higher performance；This Outside, the first pin 7 and the second pin 8 and the binding strength and reliability of frame 11 are also improved.

Fig. 4 is the schematic top plan view of pin of the present utility model and frame, and Fig. 5 is prior art using laser spot welding Mode makes the example that pin is combined with frame, wherein, Fig. 5 the first conducting terminal 19, the second conducting terminal 20 respectively with Fig. 4 The first pin 7 and the second pin 8 it is corresponding, the area of frame 11 shared by the first conducting terminal 19, the second conducting terminal 20 For 1.73*3.1mm or so, and the first pin 7 as conducting terminal and the institute of the second pin 8 in Fig. 4 present embodiment The area for taking frame 11 is 1*2.25mm or so.It readily apparent that, replaced from Fig. 4 and Fig. 5 using surface mount process For laser spot welding and pin configuration of the present utility model is used, the space in the pin arm of force direction of prior art can be released, Sky of the significant spatial shared by less than the first conducting terminal 19, the second conducting terminal 20 shared by first pin 7 and the second pin 8 Between, therefore, the pin of present embodiment reduces space-consuming, particularly in the case where microphone device overall dimensions are constant, This effect for reducing space-consuming becomes apparent from, and can do magnetic circuit bigger, which thereby enhances the performance of microphone device.

Above-described is only embodiment of the present utility model, it should be noted here that the ordinary skill for this area For personnel, on the premise of not departing from the utility model and creating design, improvement can also be made, but these belong to this practicality New protection domain.
