The invention discloses a vibration exciter for electronic products and electronic products. The vibration exciter includes a first vibrating component and a second vibrating component, and a shrapnel, the shrapnel is located between the first vibrating component and the second vibrating component, the shrapnel has a central area and two annular cantilevers, the The annular cantilevers are connected to the central area, and edge connection areas are respectively formed on the two annular cantilevers, and the two annular cantilevers are symmetrically distributed relative to the central area; the central area and the first The vibration component is connected, and the edge connection area is connected with the second vibration component; or, the central area is connected with the second vibration component, and the edge connection area is connected with the first vibration component. The invention adopts elastic pieces to connect the first vibrating component and the second vibrating component, so as to control the amplitude of the vibrating component and improve the vibration stability of the vibrating exciter.
Description
technical field [0001] The invention belongs to the technical field of electroacoustic conversion, and in particular, the invention relates to a vibration exciter for electronic products and the electronic products. Background technique [0002] The sound generating device is an important electroacoustic transducer element in electronic products, which is used to convert current signals into acoustic signals. With the rapid development of electronic products in recent years, the sound generating devices applied to electronic products have also been improved accordingly. [0003] In some electronic products, exciters are provided on sound-generating components. The vibration of the exciter drives the sound-generating part to vibrate and produce sound, but the shrapnel connection of the existing exciter is not firm, which affects the vibration effect of the exciter. When the exciter is applied to electronic products, it affects the sound generation performance of the electron...
