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: The present invention relates to the technical field of electronic products, and provides a linear vibration motor. The linear vibration motor comprises a motor housing, a stator, a vibrator, and two elastic supports for suspending the vibrator within the motor housing, for supporting the vibrator and for providing elastic restoring forces, wherein the elastic supports are located at two ends of the vibrator in a vibration direction respectively. Each of the elastic supports is made up of a plurality of elastic sheets whose one ends are fixedly connected in sequence, which are arranged side by side and which have C-shaped openings respectively. Each of the elastic supports comprises a first connection point fixedly connected to the vibrator and a second connection point fixedly connected to the inner wall of the motor housing. Therefore, the polarization phenomenon of a vibration block is reduced when the vibration feedback to a user's touch operation is realized, the noise is reduced, and the stability and the reliability of the entire linear vibration motor are improved.
