Abstract: A loudspeaker module comprising a module casing. A loudspeaker unit body (30) is accommodated within the module casing. The loudspeaker unit body (30) comprises a unit body front cover (32) and a unit body casing (34) which are combined with each other. A vibration system and a magnetic circuit system are accommodated within a space enclosed by the unit body front cover (32) and the unit body casing (34). A plurality of positioning columns (340) are arranged outside sidewalls of the unit body casing (34). Each of the positioning columns (340) protrudes out of the surface of the sidewall of the unit body casing (34), and extends from the upper end of the unit body casing (34) to the lower end of the unit body casing (34) along the sidewall of the unit body casing (34). Positioning bosses (22) are individually arranged at positions on the module casing corresponding to the positioning columns (340). Positioning holes (222) which are adapted for the positioning columns (340) are individually vertically arranged on the positioning bosses (22). The positioning structure for a unit body of the loudspeaker module is small, and occupies smaller space. The module has high acoustic performances, and the assembly process of the module is simple and easy to operate.

Abstract: Disclosed is a vibration sound-producing apparatus. A sound output aperture of the vibration sound-producing apparatus is provided at a lateral surface. A diaphragm corresponds to the position of the sound output aperture. A flat sound coil is perpendicular to the diaphragm. A magnet is parallel to the sound coil. The vibrating direction of the sound coil avoids a thickness direction. The vibrating direction of the magnet and a mass block also avoids the thickness direction. The mass block is fixedly joined to a housing via a flexible piece. This facilitates reduced product thickness, increased product performance, and a simplified product production process. Therefore, the vibration sound-producing apparatus of the present invention has the advantages of a great thickness-reduced design, great performance, and simple assembly.

Abstract: Disclosed is a loudspeaker module applied inside a terminal, wherein, the terminal comprises a terminal housing, and the loudspeaker module is fixed inside the terminal. The loudspeaker module comprises a loudspeaker unit and a module housing for accommodating and fixing the loudspeaker unit. A closed space formed by the loudspeaker unit, an outer wall of the module housing, and the terminal housing is a rear sound cavity. By means of the loudspeaker module provided in the present invention, the usable space inside the terminal can be converted into the rear sound cavity, so that the space of the rear sound cavity is enlarged, and the acoustic performance of the loudspeaker module can be effectively improved. Therefore, the present invention makes full use of the inside space of the terminal to realize the thinning of the loudspeaker module without changing the inside space of the terminal, and achieves good acoustic performance.

Abstract: A linear vibration motor having elastic pieces provided with vibration arms comprises housing, a mass block, and elastic pieces. The elastic pieces connect the mass block and the housing to provide an elastic force in Z axis direction such that the mass block performs a movement up and down. The elastic pieces are provided with two vibration arms, and the two vibration arms are symmetrical about the X axis when rotating 180 degrees around the X axis. The elastic pieces are S-shaped or inverted Z-shaped, or formed by the combination of two V-shaped vibration arms. The elastic pieces have two or four elastic pieces, and disposed on symmetrical two sides of the mass block.
