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 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 linear vibration motor 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.
