Abstract
A rectangular microspeaker according to the present invention transfers vibration sound through the front surface or side surface of a diaphragm. In order to maximize an effective vibration area and to expand a volume, all parts including a frame are fabricated in a rectangular shape. The present invention is applied to a P type, an F type, and a composite type. The vibration sound generated on the bottom of the diaphragm as well as the vibration sound generated on the top of the diaphragm may be discharged through the side surface. A magnetic field part may be insert-molded separately or along with the frame.
