Problems solved by technology

[0004] 1) One end of the voice coil lead wire vibrates with the vibration of the voice coil, and the other end is fixed to the pot frame, so there will be internal stress and it is easy to break;
[0005] 2) The voice coil leads occupy the magnetic circuit space;
[0006] 3) The lead wire of the voice coil occupies the vibration space of the diaphragm, and the lead wire will vibrate with the vibration of the diaphragm. Therefore, it is necessary to reserve a space for the vibration of the diaphragm when designing the lead wire of the voice coil, which will cause the electro-acoustic conversion device to vibrate. increase in volume;
[0007] 4) The voice coil lead wire needs to be welded with the pad on the basin frame, and the part of the voice coil lead wire that does not participate in the vibration needs to be fixed to the basin frame with glue, and the fixing glue will also occupy a certain space, resulting in the failure of the electroacoustic conversion device. overall volume increase
