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: A multifunction apparatus, comprising an outer housing and a vibration system, a magnetic circuit system and an elastic supporting member. The magnetic circuit system is fixed by the elastic supporting member and is suspended inside the outer housing. The vibration circuit system comprises a diaphragm and a voice coil. The elastic support member comprises a first fixing portion and a second fixing portion having different heights, and a deformation portion connected with the first fixing portion and the second fixing portion. An orthographic projection of the elastic supporting member in a vibration direction is a polygon or an oval shape. The first fixing portion or the second fixing portion is located at an edge of the elastic supporting member, and four straight edges of the first fixing portion or the second fixing portion are disposed corresponding to a rectangular bottom wall of the magnetic circuit system or the outer housing. The elastic supporting member of the invention does not occupy a horizontal space of the magnetic circuit system, and thus a magnet with large size can be accommodated, and a BL value of a vibrating sound-producing apparatus can be increased; further, since the elastic supporting member is a three-dimensional structure, the length and width of the deformation portion is not limited, facilitating adjustment of an F0 value of the vibrating sound-producing apparatus.

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.
