Abstract
PURPOSE:To improve the input-resisting property and maximum output sound pressure by lessening a rise in the temperature of a voice coil by radiating the heat of the voice coil via a heat sink. CONSTITUTION:Yoke 2 and center pole 1 of a vibrating type lould-speaker are formed in a body and ring-shaped magnet 4 is bonded to yoke 2 to form a ring- shaped magnetic space between the inside circumferential surface of ring-shaped yoke 3 fixed on the top of magnet 4 and the outside circumferential surface of pole 1. Then, the outside circumference of diaphragm 13 is supported by frame 8 via edge member 7 and diaphragm 13 is fixed to hollow cylindrical bobbin 14 with incorporated vioce coil 10 and supported by frame 8 via damper 12, thereby using bobbin 14 as a heat pipe. The heat of voice coil 10 is radiated via diaphragm 13 to lessen a rise in the temperature of voice coil 10 and the input-resisting property of the loudspeaker is improved to increase maximum output sound pressure.
