Abstract:
The application relates to a vibration sounding device including: a housing body with a containment cavity and a sounding unit arranged in the containment cavity. The sounding unit includes a vibration system and a magnetic circuit system. The magnetic circuit system includes a main magnet and a secondary magnet assembly. The vibration sounding device also includes an elastic assembly, a weight assembly, and a drive coil. The second direction is perpendicular to the first direction. By virtue of the configuration, it is beneficial to simplify the forming process of the weight assembly, reduce the production cost, and also facilitate the replacement of the drive coil.
