Abstract: A speaker module comprising a module housing is disclosed. A speaker unit is accommodated within the module housing. A sound hole of the module is located at a side of the speaker unit. The speaker unit divides a cavity of the entire module into two cavities, namely a front acoustic cavity and a rear acoustic cavity. The front acoustic cavity is in communication with the sound hole. A sound-absorbing cotton is provided in the front acoustic cavity. The sound-absorbing cotton is fixed on the module housing, and is arranged to avoid a vibration space of a diaphragm of the speaker unit. The present invention effectively improves the performance of a sensitivity curve of the module at high frequencies without modifying the structure of the front acoustic cavity, thus not only increasing the acoustic performance of the module, but also simplifying the structure of the front acoustic cavity of the module.

Abstract: Disclosed is a vibration sound-producing apparatus. A sound output aperture is provided on a sidewall perpendicular to a thickness direction. A diaphragm is parallel to the plane on which the sound output aperture is located. A flat sound coil is perpendicular to the diaphragm. Two magnets parallel to the sound coil are arranged at either side of the sound coil. The vibrating direction of the sound coil avoids the thickness direction. The vibrating direction of an integral structure of the magnets and a magnetic conductor part also avoids the thickness direction. This facilitates a thickness-reduced design for a product, increases the space for vibration, and enhances product performance, meanwhile, the design of the two magnets effectively increases the strength of the magnetic field within the product, this further improving product performance. The vibration sound-producing apparatus of the present invention has the advantages of a great thickness-reduced design and great performance.

Abstract: Disclosed is a loudspeaker module which comprises a housing and a loudspeaker unit accommodated in the housing. The housing comprises a front cover, a first housing and a second housing, and a cavity is defined by the front cover, the first housing and the second housing. The loudspeaker unit is fixed in the cavity, and the cavity is divided into a front cavity and a rear cavity by the loudspeaker unit. The front cavity is a cavity defined by the loudspeaker unit, the front cover and the first housing. The loudspeaker unit comprises a vibration system and a magnetic circuit system. The front cover is provided with a cavity opposite to a mounting position of the loudspeaker unit, and the cavity is isolated from the front cavity and the rear cavity and is provided with a ventilation structure in communication with external environment. The loudspeaker module of the present invention has the advantage of good acoustic performance.
