Abstract
A multifunctional sound device includes a housing, a sound unit, a vibrator, and a coil. The housing includes an accommodating cavity, and the sound unit is suspended in the accommodating cavity. The sound unit includes a frame, a vibration system, and a magnetic circuit system. The vibration system is fixed in the frame, and the magnetic circuit system drives the vibration system to vibrate and generate sound along a first direction, where the magnetic circuit system includes a magnetic gap. Since the speaker and the motor share one magnetic system, the sound unit and the vibrator are assembled in the housing, which greatly reduces occupied space. The sound unit and the vibrator form a dual-vibration system, and the sound unit cooperatively vibrates with the vibrator in addition to generating sound, which improves vibration effects and further avoids adding other components, thereby saving space.
