发明名称 Speaker device
摘要 The object of the present invention is that the surplus vibration involved therewith simultaneously generating a sound wave by the vibration of the vibrating cone of the loudspeaker unit is generated in the loudspeaker system, which has impaired the sound quality of the loudspeaker system. The purpose of the present invention is to provide a technique for improving the sound quality by reducing the this surplus vibration which are the loudspeaker frame vibration and the cabinet vibration like a front baffle vibration. The present invention is characterized in being configured with a viscoelastic material layer upon rear portions such as the frame surface of the loudspeaker unit and inside and outside surfaces of each surface configuring the loudspeaker cabinet, and additionally suppresses vibration by addition of a heavy member or pressurization caused by constraint of a binding member.
