摘要： An electromagnetic actuator comprises: a magnet; a pole piece mounted to the magnet; a yoke facing the pole piece; a coil base having a vibration coil; leaf springs for supporting the coil base and a weight; a case for enclosing them; a cover for covering one side of the case; and a diaphragm having a voice coil, wherein the arms of the coil base are inserted through notches formed in the yoke, and the vibration coil and the voice coil is disposed in a gap in which the pole piece and the yoke face each other. The weight vibrates by the application of a low-frequency current to the vibration coil, and the diaphragm vibrates by the application of a high-frequency current to the voice coil.
