MULTI-FUNCTION MICRO-SPEAKER

摘要

PURPOSE: The multifunction microspeaker improves the braking power of vibrator and unstable oscillations by minimizing interference between the vibrator occurring vibration and the vibration plate occurring acoustic. CONSTITUTION: The peripheral part of the vibration plate(20) is fixed to the frame(10). One side of the first elastic member(40) carrying the elasticity is fixed to frame. The yoke(50) having accommodating groove is fixed to the first elastic member. The first permanent magnet(60) is fixed to the floor side of the accommodating groove.
