FLAT PLATE TYPE BASS LOUDSPEAKER

摘要

The present invention provides a flat plate type bass loudspeaker comprising a flat plate-shaped vibration diaphragm, at least three driving units independent of each other and a housing. The driving unit comprises a voice coil unit and a magnetic circuit unit corresponding to the voice coil unit; the voice coil units are dispersedly combined and fixed at one side of the vibration diaphragm near the housing; mounting holes for accommodating and fixing the magnetic circuit units, and voice outlet holes penetrating through the housing and communicated with the outside are arranged on the housing; the number and position of the mounting holes are corresponding to the number and position of voice coils attached to the spherical top of the vibration diaphragm; and the ratio of the total area of the voice outlet holes to the orthographic projection area of the vibration diaphragm on the housing is within a numerical range less than 0.9. The flat plate type bass loudspeaker provided in the present invention can address the problems of thick and heavy voice coils and excessive magnet performance.
