Patent ID: 8139813

Claim:
A speaker device comprising: a diaphragm; a frame supporting the diaphragm vibratably in a vibration direction of the diaphragm; a magnetic circuit disposed in the frame; and a driving member adapted to drive the diaphragm, wherein the driving member comprises: a driving part comprising a voice coil movably disposed in a magnetic gap of the magnetic circuit, wherein the driving part is formed movably in a direction different from the vibration direction of the diaphragm; and a rigid angle conversion and transmission part, wherein one end of the rigid angle conversion and transmission part is angle-variably joined to the driving part, wherein another end of the rigid angle conversion and transmission part is angle-variably joined to the diaphragm, and wherein the rigid angle conversion and transmission part is obliquely disposed with respect to each of the vibration direction of the diaphragm and the moving direction of the driving part.
