Abstract
A flat speaker device capable of emitting loud reproduced sound with a relatively simple configuration is provided. The speaker device includes a diaphragm, a frame supporting the diaphragm vibratably in the vibration direction, a magnetic circuit disposed in the frame, and a driving member for driving the diaphragm. The driving member includes a voice coil movably disposed in a magnetic gap of the magnetic circuit, a driving part formed movably in a direction different from the vibration direction of the diaphragm, and an angle conversion and transmission part, one end of which is angle-variably joined to the driving part and another end of which is angle-variably joined to the diaphragm. The angle conversion and transmission part has rigidity and is obliquely disposed with respect to each of the vibration direction of the diaphragm and the moving direction of the driving part.
