摘要： A speaker includes a shell, a magnetic circuit unit, and a vibration unit. The magnetic circuit unit includes a yoke and a magnet. The yoke includes a bottom wall connected to the magnet. The bottom wall includes an upper surface close to the vibration unit, and a lower surface opposite to the upper surface. A first groove and a second groove that are spaced apart from each other are formed on the upper surface by recessing towards the lower surface. An orthographic projection of the magnet on the upper surface along a vibrating direction of the vibration unit completely covers the first groove. The second groove is arranged outside the orthographic projection. The magnet and the bottom wall are glued and connected by a glue. The glue is received in the first groove. In the speaker, the magnet is firmly connected and is unlikely to be detached.

摘要： An electroacoustic transducer includes: a diaphragm; a frame that is disposed around the diaphragm so as to surround the diaphragm; an edge that closes a space between the diaphragm and the frame in a manner of forming a membrane so as to connect the diaphragm and the frame; a base body that supports the frame and has a through sound output hole in front of the diaphragm; a magnet that is attached to the frame; and a voice coil body that is attached to the diaphragm. The frame has an annular first fitting portion that is disposed around the diaphragm so as to surround the diaphragm. The base body has a second fitting portion that fits with the first fitting portion. The electroacoustic transducer further includes a sealing member that is made of a thermoplastic substance and seals a space between the first fitting portion and the second fitting portion fitted with each other.

摘要： 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.

摘要： An edge for a speaker making it possible to decrease a thickness of the speaker and achieve cost reduction by using no damper without lowering a sound quality is provided. The edge of a speaker is in a sheet-like and ring form and includes an outer fixing part formed on its outer peripheral part for fixing the edge to the frame (supporting member), an inner fixing part formed on its inner peripheral part for fixing the edge to the diaphragm, and a sheet-like part lying between the inner fixing part and the outer fixing part (connecting the inner fixing part and the outer fixing part). The respective convex portions are formed at least on both surfaces of the sheet-like part at the boundary portion of the sheet-like part and the outer fixing part, thereby forming the control parts for controlling the vibration of the diaphragm.
