Abstract:

The present application provides a diaphragm and a loudspeaker. The diaphragm comprises an elastic body and a conductive grid layer attached and fixed to the elastic body; the conductive grid layer comprises several metal wires arranged at intervals and several plastic wires arranged in cross arrangement with the metal wires. Compared with the related art, an FPC is replaced with the conductive grid layer made of conductive metal wires and several plastic wires arranged in cross arrangement with the metal wires in the present application; thus, the problem of fatigue fracture of the FPC is avoided, and the reliability, the service life and/or the low-frequency performance of the loudspeaker are improved; moreover, the assembly procedures are reduced, the cost is reduced, and the assembly speed and precision are improved.
