LOUDSPEAKER DEVICE

PROBLEM TO BE SOLVED: To provide a loudspeaker device for inhibiting the generation of regions at a low sound-pressure level in a middle sound region and a high-pitched sound region and ensuring the continuity of the sound pressure level. SOLUTION: The outer edges of diaphragms 7 are installed to frames 9 through edge sections 8, and sub-diaphragms 10 are mounted at places where the modes of a resonance in edge sections 8 are generated. The diaphragm sections of the sub-diaphragms 10 are extended in the outer peripheral direction of the diaphragms 7 from the places of the mounting. The sub-diaphragms 10 are arranged on the front side of the loudspeaker device SP. The sub-diaphragms 10 are vibrated in a frequency region in which the diaphragms 7 and the edge sections 8 are resonated. COPYRIGHT: (C)2006,JPO&NCIPI
