摘要 PURPOSE:To complete a radiator system by a speaker itself by using the radiator in common use with a protecting plate of a diaphragm. CONSTITUTION:When a high input is applied to the speaker, a heat generated in a voice coil 1 moves to a heat pipe 2 via a center pole 3, is delivered to the radiator 14 quickly and discharged into external air. In case of a woofer especially, since the amplitude of the diaphragm 9 is large and the air flow produced by the vibration of the diaphragm 9 cools forcibly the radiator 14 in common use with the protecting plate on the entire face of the diaphragm 9, the heat dissipation effect is high. Thus, the temperature rise of the voice coil 1 is suppressed, then the decrease in the sound pressure level due to the heating of the voice coil and a change for disconnection are decreased.
