Tablet Woofer

摘要

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.
