IPC: H04R23/00
Filed: 2004-03-10
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that energy loss is large and linearity in conversion from a sound signal into an acoustic wave is damaged since rotation driving force of a motor is converted into reciprocal driving force on a straight line and a diaphragm is vibrated by reciprocal driving force although a speaker system where the diaphragm is compulsorily vibrated by driving force and the acoustic wave is generated while rotation of the dynamo-electric motor is reciprocally reversed is proposed.  <P>SOLUTION: The speaker system S1 is provided with a volume variable part V1 and a first rotation driving means M1. The volume variable part V1 has a first member B1 and a second member D1. The first member B1 is supported so that it can be displaced in a circumferential direction with a rotation center axis as a center. The first member B1 is relatively displaced in the circumferential direction with respect to the second member D1. Thus, the volume on a front side of the volume variable part V1 changes. The first rotation driving means M1 fluctuates the first member B1 in the circumferential direction of the rotation center axis. Thus, the volume of a front side of the volume variable part V1 is increased and decreased and the acoustic wave is generated.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
