The present invention relates to a high-output microspeaker, and more particularly, to a high-output microspeaker which includes a damper for preventing lateral vibrations of a diaphragm. The present invention discloses a high-output microspeaker, comprising: a frame; a protector; a yoke assembly coupled to the frame and including a magnet; a diaphragm provided in the frame and producing vibration; a voice coil coupled to the diaphragm and vibrating the diaphragm; a terminal provided on one side of the frame and providing an electrical connection between the lead wire of the voice coil and an external terminal; and a damper formed of an FPCB that includes an inner portion to which a center diaphragm, a side diaphragm and the voice coil are attached, an outer portion to which the side diaphragm is attached and which is in contact with the frame and the protector, a support portion functioning to connect the voice coil, the outer portion and the inner portion and including a land portion to which the lead-in wire of the coil is soldered or welded, and a connecting portion extending outward from the outer portion and providing an electrical connection between the terminal provided on the frame and the outer portion.
