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 improvement of thinner and miniaturized design of portable electronic terminals, the existing vibration and sound generating devices cannot meet the development trend of thinner and miniaturized

Abstract

The invention discloses a vibration sound generating device. A sound outlet hole of the vibration sound generating device is arranged on a sidewall which is perpendicular to the thickness direction. A vibration diaphragm is parallel with a plane on which the sound outlet hole is arranged. A flat voice coil is arranged perpendicularly with the vibration diaphragm. A magnet is arranged in parallel with the voice coil. The vibration direction of the voice coil is different from the thickness direction. The vibration direction of an integrated structure which is composed of the magnet and a mass block is also different from the thickness direction, thereby facilitating small-thickness design of the product. Furthermore, a vibration space can be enlarged and product performance can be improved. The vibration sound generating device has advantages of high thinning degree and high performance.

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...
