Abstract: A loudspeaker module includes, but is not limited to, an independent housing enclosing a sealed cavity. The independent housing is provided with an opening communicating the cavity with the exterior. The loudspeaker module further includes, but is not limited to, a loudspeaker unit including, but not limited to, a vibration system, a magnetic circuit system and a casing and a front cover that receive the vibration system and the magnetic circuit system, a sidewall of the casing is provided with a rear sound aperture. An acoustic wave above the vibration system directly radiates to the exterior, and an acoustic wave below the vibration system radiates to a side via the rear sound aperture. The loudspeaker unit and the independent housing combine so that the rear sound aperture and the opening are sealingly engaged and communicate. The cavity of the independent housing forms a rear acoustic cavity of the loudspeaker module.

Abstract: The present invention provides a speaker structure, comprising a vibrating component, an electromagnetic component, an casing and an integral washer conductive sheet. The electromagnetic component comprises a central magnet and peripheral magnets which are disposed around the central magnet. The integral washer conductive sheet replaces a washer structure and an conductive sheet structure in a traditional speaker structure and is integrally formed by the washer and an conductive sheet which are combined into one part. The integral washer conductive sheet comprises a washer part and an conductive sheet part, wherein the washer part is disposed on the peripheral magnets and the conductive sheet part extends out of the casing. By adopting the integral washer conductive sheet according to the present invention, those skilled in the art can simplify an internal structure of the speaker, save production materials, simplify molding and assembling procedures, and improve production efficiency.

Abstract: The loudspeaker module includes a loudspeaker unit including a front cover and a casing engaged together, a vibration system, and a magnetic circuit system received in a space enclosed by the front cover and casing. The loudspeaker module further includes an independent housing enclosing a sealed cavity. The independent housing is provided with an opening communicating the cavity with the exterior. A sidewall of the casing is provided with a rear sound aperture radiating an acoustic wave to a side. The side of the loudspeaker unit provided with the rear sound aperture is sealingly engaged with the independent housing at the opening. A structure of the opening matches with the loudspeaker unit. The rear sound aperture communicates with the cavity. After the loudspeaker unit is engaged with the independent housing, the cavity forms a rear acoustic cavity of the loudspeaker module.
