发明名称 Slim Microspeaker
摘要 A microspeaker includes a frame, magnetic circuit, voice coil configured to generate vibration by mutual electromagnetic force with the magnetic circuit, vibration plate configured to vibrate together according to the vibration of the voice coil to generate a sound, and suspension configured to guide a vibration direction of the vibration plate and voice coil. The suspension has a central portion attached to the voice coil, an annular outer circumferential portion formed to be spaced apart from the central portion by a predetermined interval, and a connection portion connecting the central and outer circumferential portions and configured to perform a damping function. The central portion has an outer end having the same height as the connection and outer circumferential portions, an inner end positioned to be higher than the outer end, and a step portion connecting the outer end and inner end. The voice coil is attached to the inner end.
