Abstract: The present invention provides a tablet woofer, including: a vibration diaphragm, at least four mutually independent driving units, and a housing for accommodating and securing the vibration diaphragm and the driving unit. The driving unit includes independent voice coil units and magnetic circuit units, the voice coil units being attached and fixed to the vibration diaphragm. The woofer further includes a FPCB communicating with an internal circuit and an external circuit, and the FPCB is disposed at two sides of the housing, the part of the FPCB disposed on the side of the housing close to the voice coil units being electrically connected to the voice coil units, the part of the FPCB disposed on the side of the housing far away from the voice coil units being electrically connected to the external circuit. The woofer can solve the problems of thick and heavy voice coils and magnet performance surplus.

Abstract: A flat plate bass loudspeaker comprising a flat plate diaphragm, at least three driving units and a housing. The driving unit comprises a voice coil unit and a magnetic circuit unit; the voice coil units are dispersedly coupled to one side of the diaphragm near the housing; mounting holes for accommodating and fixing the magnetic circuit units, and voice outlet holes penetrating through the housing are arranged on the housing; the number and position of the mounting holes are corresponding to those of voice coils attached to the spherical top of the diaphragm; and ratio of the total area of the voice outlet holes to the orthographic projection area of the diaphragm on the housing is in a range less than 0.9. The flat plate bass loudspeaker provided by the present invention can avoid the problems occurred in thick and heavy voice coils and excessive magnet performance.
