Patent ID: 7965856

Claim:
A speaker unit comprising a speaker device 8 , and a frame 1 made of a synthetic resin and having an opening in an acoustic wave generating direction of the speaker device 8 to accommodate the speaker device 8 , the speaker device 8 comprising a magnet 6 ; a pole piece 7 and a yoke 5 disposed on opposite polar faces of the magnet 6 ; an annular space S defined by an outer peripheral surface of the pole piece 7 having a central axis parallel to the acoustic wave generating direction and an inner peripheral surface of the yoke 5 , which are opposed to each other; a cylindrical voice coil 9 placed in the space S; and a diaphragm 3 that is coupled to the voice coil 9 and vibrates in the acoustic wave generating direction, the diaphragm 3 having an inner periphery 31 thereof coupled to one end of the voice coil 9 , the diaphragm 3 having an outer periphery 32 thereof coupled to the frame 1 , the voice coil 9 having a pair of lead wires 90 , 90 extended therefrom, passed between the yoke 5 and the diaphragms 3 , and led out of the frame 1 , the frame 1 having a receiving surface 11 for receiving collisions of the lead wires 90 , 90 due to vibrations of the diaphragm 3 , which is formed outer than an end face 53 of the yoke 5 opposed to the diaphragm 3 , and closer to the diaphragm 3 than the end face 53 .
