Sound production device and electronic equipment

Abstract

The invention discloses a sound production device and electronic equipment. The sound production device comprises a support, a vibration unit and at least two groups of elastic parts: a first elastic assembly with at least one first elastic connecting piece, wherein the first elastic connecting piece is connected with the support and the vibration unit; a second elastic assembly with at least one second elastic connecting piece, wherein the second elastic connecting piece is connected with the support and the vibration unit, and the first elastic assembly and the second elastic assembly are fixed at different height positions in the height direction of the voice coil; the voice coil is defined to have a first end face in the height direction, the first elastic component is projected on the first end face to form a first projection area, the second elastic component is projected on the first end face to form a second projection area, and at least part of the first projection area is located outside the second projection area; or the first projection area is overlapped with the second projection area. According to the technical scheme, it is ensured that the elastic connecting piece still has good reliability when the vibration unit displaces greatly, and the stability of the sound production device is ensured.

Description

technical field [0001] The invention relates to the field of electroacoustic technology, in particular to a sound generating device and electronic equipment. Background technique [0002] The sound generating device is an important acoustic component in electronic equipment, which is a transducer device that converts electrical signals into acoustic signals. At present, with the continuous progress and innovation of technology, the structural design of traditional sound generating devices is also constantly seeking innovation and change. It not only needs to meet the development trend of thinning, but also pays more and more attention to performance optimization, and takes into account the process. Simplification and cost control. [0003] In the existing sounding device, elastic connectors are fixed on the voice coil skeleton to prevent the voice coil from being polarized in the non-vibration direction during the vibration process. With the improvement of speaker performan...

AI Technical Summary

Problems solved by technology

[0003] In the existing sounding device, elastic connectors are fixed on the voice coil frame to prevent the voice coil from being polarized in the non-vibration direction during the vibration process. With the improvement of the performance requirements of the speaker in the industry, the voice coil reaches a large displacement When used, the reliability of ordinary elastic connectors is low, and there will be fractures, resulting in failure of the sounding device
