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.
