Abstract
A double-sided sounding device is disclosed. The double-sided sounding device includes an upper vibration system and a lower vibration system. The upper vibration system includes an upper voice coil, and the lower vibration system includes a lower voice coil. The upper voice coil includes a first voice coil and a second voice coil respectively arranged on two opposite sides of the lower voice coil along a direction of a long axis of the double-sided sounding device. The double-sided sounding device reduces the product width, has symmetrical electromagnetic force performances of the upper voice coil and the lower voice coil, and eliminates mutual interferences between the upper voice coil and the lower voice coil when working.
