Fig. 3 is the combining structure schematic diagram of electro-acoustic conversion device.
Specific embodiment
Hereinafter with reference to correlative type, illustrate the electro-acoustic conversion device of the provided embodiment of this creation.Please refer to Fig. 1 and figure
2, a kind of electro-acoustic conversion device is painted in figure, includes vibration module 10 and frame 60.Vibration module 10 is by voice coil 11, vibrating diaphragm 13
And connector 20 is constituted, and voice coil 11 is set to the central part on 13 surface of vibrating diaphragm.
Connector 20 is general circlewise and to be integrally formed at the outer peripheral edge of vibrating diaphragm 13, includes assembled portion 21 and conductive connection part 22
Positioned at the side of assembled portion 21, conductive connection part 22 has spaced two conductive terminal 23 for being electrically connected from voice coil 11
Two conducting wires 12 extended.
Connector 20 be fixedly arranged on vibrating diaphragm 13 outer peripheral edge and fixed two conductive terminal 23.
In implementation, vibration module 10 is connected to the engaging portion 61 (as shown in Figure 3) of frame 60 using assembled portion 21, so that sound
Circle 11 is located in the room that vibrating diaphragm 13 and frame 60 are constituted.
Electro-acoustic conversion device further includes terminal external piece 70, as the company between two conductive terminals 23 and an at least cable
