The present invention relates to a slim microspeaker with a thin thickness and, more specifically, to a slim microspeaker which is slimmed by changing a suspension structure. The present invention comprises: a frame; a magnetic circuit; a voice coil which is vibrated by a mutual electromagnetic force with the magnetic circuit; a vibrating plate which is also vibrated by a vibration of the voice coil and generates a sound; a central part which guides a vibrating direction of the vibrating plate and the voice coil and is attached with the voice coil; a ring-shaped circumferential part which is disposed at a certain space from the central part; and a suspension which connects the central part and the circumferential part and is equipped with a connecting part which plays a role of damping. The central part comprises: an outer side end which has a height identical to the heights of the connecting part and the circumferential part; an inner side end which has a height higher than the height of the outer side end; and a stepped part which connects the outer side end and the inner side end. The voice coil is attached to the inner side end. |
