<P>PROBLEM TO BE SOLVED: To provide a speaker device which expands a sound propagation range by a resonance effect. <P>SOLUTION: In the speaker device, a vibration panel is constituted of a natural material, and driving means (16A and 16B) for converting the electric signal of sound to mechanical vibration are provided in the vicinity of the curved apex of the vibration panel. The vibration panel comprises: a first vibration panel (14) with a curved shape; plural vibration propagation members (13) connected with the first vibration panel (14) and extending outward; and a second vibration panel (12) stretched tightly and joined with the vibration propagation members (13). The first vibration panel (14) and the vibration propagation members (13) are interconnected via fixation means (15A to 15H) provided in an attachable and detachable manner. <P>COPYRIGHT: (C)2013,JPO&INPIT |
