摘要： The present disclosure discloses a multifunctional sounding device including a frame, a vibrator assembly, and a speaker assembly. The frame includes a top wall and a bottom wall. The vibrator assembly includes a vibrating unit vibrating along a first direction. The speaker assembly includes two magnetic units locating on two opposite sides of the vibrating unit respectively, a diaphragm fixed to the top wall, and two voice coils. The diaphragm vibrates along a second direction that is perpendicular to the first direction. A winding axis of each voice coil is perpendicular to the first and second directions. The two magnetic units are sandwiched between the top wall and the bottom wall. A peripheral edge of the diaphragm is recessed inward for avoiding the two magnetic units. The multifunctional sounding device disclosed by the present disclosure combines functions of emitting sounds and providing vibrations.

摘要： A multifunctional sound device includes a housing, a sound unit, a vibrator, and coils. The housing includes an accommodating cavity, and the sound unit is accommodated in the accommodating cavity and is fixedly connected to the housing. The sound unit includes a frame, a vibration system, and a magnetic circuit system. The vibration system is disposed in the frame, and the magnetic circuit system drives the vibration system to reciprocally vibrate and generate sound along a first direction. The sound unit and the vibrator are assembled in the housing and share one magnetic system, which saves space and greatly reduces occupied space. Moreover, the magnetic circuit system interacts with the coils to drive the vibrator to vibrate in the second direction and the third direction, thereby enhancing vibration effect.
