| titleOfInvention | Flat plat type bass loudspeaker |
| abstract | Provided in the utility model is a flat plat type bass loudspeaker comprising a vibrating diaphragm, at least four driving units independent of each other, and a housing. The vibrating diaphragm in a flat plate shape includes a ball top portion arranged in the center and a folded ring portion arranged at the edge. The driving units include independent voice coil units and magnetic circuit units corresponding to the voice coil units; and the four voice coil units are respectively contacted with and fixed at four corners of the ball top portion of the vibrating diaphragm. Installing holes that are used for accommodating and fixing the magnetic circuit units are arranged at the housing; and the upper side surface of the housing is fixedly combined with the edge of the folded ring portion. The flat plat type bass loudspeaker also includes flexible printed circuit boards (FPCB) communicating an internal circuit and an external circuit of the loudspeaker; the FPCBs are arranged at the two sides of the housing. One sides, approaching the voice coil units, of the FPCBs are electrically connected with voice coil leads; and the other sides, far away from the voice coil units, are electrically connected with the external circuit of the loudspeaker. With the flat plat type bass loudspeaker, problems of heavy weight of the voice coils and performance excess of the magnets can be solved. |
