Abstract
Disclosed herein is a hybrid acoustic apparatus. The hybrid acoustic apparatus includes: a rectangular microspeaker used as a first acoustic device; and a second acoustic device integrated with the microspeaker. The microspeaker includes a plate configured to constitute a part of a magnetic field part, a magnet configured to be disposed beneath the plate, a diaphragm configured to be disposed on the plate, and a frame configured to accommodate the diaphragm, the plate, and the magnet. A path of vibration sound generated by the diaphragm is formed to be perpendicular to a direction in which the diaphragm vibrates so that the vibration sound is discharged through a side surface of the diaphragm.
