Abstract: A woofer speaker is provided, comprising a woofer speaker unit, a first sealing pad, a second sealing pad and a housing. The first sealing pad is fixed closely with the outer edge of the housing; the woofer speaker unit is fixed and sealed within the housing by the first sealing pad, and the second sealing pad is located between the woofer speaker unit and the housing; a sound hole is provided on the housing, and the shape and size of the sound hole correspond to those of the woofer speaker; and the terminal installation plane is the rear cover of the woofer speaker, and together with the housing forms the rear sound cavity of the woofer speaker through the first sealing pad. The cavity of the woofer speaker provided by the invention and the installation terminal applying the woofer speaker resolve the rear cover vibration problem of ultra-thin woofer speakers.

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.
