Patent ID: 8290198

Claim:
A speaker device, comprising: a pair of diaphragms disposed opposite each other, a frame configured to vibratably support an outer periphery of said diaphragms in a vibration direction, and a plurality of driving parts configured to support a rear surface of each of said diaphragms and vibrate said diaphragms in response to an audio signal, wherein said plurality of said driving parts include: a pair of magnetic circuits in which a magnetic gap is formed in a direction different from the vibration direction of said diaphragms, a pair of voice coils vibratably arranged in said magnetic gap in one axis direction, vibrating so as to move toward or away from each other in response to said audio signal, and a rigid vibration direction converter part direction-converting the vibration of said voice coils and transmitting the vibration to said diaphragms, and said rigid vibration direction converter part has a hinge formed on a side of said pair of diaphragms and on a side of the opposing ends of said pair of voice coils, respectively, and a link part obliquely disposed with respect to the vibration direction of said voice coils.
