Problems solved by technology

The vibration loudspeaker with this structure is limited by the volume and vibration space of the cylindrical voice coil, and it also needs to set up a mass part in the vertical direction to combine with the magnetic circuit system, which increases the thickness in the vertical direction and cannot meet the thinness of the product. demand
With the promotion of thinner and miniaturized designs of portable electronic terminals, the existing vibrating and sounding devices cannot meet the development trend of thinning and miniaturization; moreover, the internal components of the vibrating and sounding devices with existing structures are complicated and difficult to assemble. Difficult issues concerned by the industry

Abstract

The invention discloses a vibrating sound production device. Sound outlet holes of the vibrating sound production device are arranged at a side surface, a vibrating diaphragm corresponds to the sound outlet holes in position, a flat voice coil is vertical with the vibrating diaphragm, magnets are parallel to the voice coil, a vibrating direction of the voice coil avoids the thickness direction, vibrating directions of the magnets and a mass block also avoid the thickness direction, and the mass block is fixedly combined with a shell through elastic pieces, thereby being conducive to reducing the product thickness, improving the product performance and simplifying the production process of products. Therefore, the vibrating sound production device disclosed by the invention has the advantages of high thinning design, good performance and simple assembly.

Description

technical field [0001] The invention relates to the field of electroacoustics, in particular to a vibration sound generating device. Background technique [0002] The vibration speaker is a multifunctional acoustic device, which not only realizes the vibration sound function of the ordinary speaker, but also has the function of a vibration motor. The vibration speaker can save the internal space of the portable electronic terminal, simplify the assembly process of the portable electronic terminal, and reduce the cost of the portable electronic terminal, so the vibration speaker has been more and more widely used in the field of portable electronic terminals. [0003] The vibration and sound generating device of the existing structure includes a vibration system and a magnetic circuit system; the vibration system includes a diaphragm and a cylindrical voice coil integrated with the diaphragm; the magnetic circuit system includes a magnet and a magnetic gap, and the cylindrica...
