出することを特徴とした全面駆動形スピーカ。 a diaphragm made of an insulating material with a coil section;
The diaphragm is equipped with a plurality of magnetic poles facing each other with a small gap on both sides, and a plate to which the plurality of magnetic poles are fixed and acoustic holes are provided between the fixed adjacent magnetic poles. In the full-plane drive type speaker, an inner end surface is in contact with both sides of the diaphragm, and a braking member is provided on the outer end surface side in contact with the acoustic hole of the plate, so that the sound waves from the diaphragm are passed through the damping member to the acoustic hole. A fully-driven speaker that emits even more energy.
