Abstract

PURPOSE:To improve sound quality and also to increase power by providing voice coils and several drive parts driving them. CONSTITUTION:This speaker has two voice coils 3 and 3' wound around both ends of bobbin 6, two magnetic circuits 1 and 1' arranged at respective coils, and diaphragm 4 supported by cone edge 23 and damper 5 nearly at the center of bobbin 6. Then, providing two vibration parts make the gravity center between diaphragm 4 and bobbin 6 agree with the center of composite drive and an ideal drive state can be obtained because of a push-pull state. Therefore, there is no what is called braying motion, etc., and an original sound can be reproduced with fidelity. Further, driving force increases, so that strong speaker power can be obtained.
