PURPOSE:To reduce the resonance of a cabinet, to promote heat dissipation of a speaker unit and also to prevent disconnection by fixing the speaker unit to the front face of the cabinet and inserting a buffer member of heat conductivity between the rear edge of the speaker unit and the inner wall of the back side of the cabinet. CONSTITUTION:In figure, 3 is a woofer fixed to the front face of the cabinet 1 by a screw 6, 2 is a tweeter fixed coaxially to the woofer 3. The buffer member 9 is inserted between a woofer yoke 3g and a rear cabinet 1b so as to suppress the vibration of the cabinet 1 or quicken the attenuation thereby preventing the generation of abnormal sound. Further, when the cabinet 1 is made of a material such as a metal or a material having a high heat conductivity, since the heat generated in a tweeter voice coil 2d and a woofer voice coil 3f is delivered to the cabinet 1 and dissipated in air by using a heat conductive material for the buffer member 9, the disconnection due to high temperature is prevented in advance. |
