Abstract
The present disclosure discloses a speaker assembly including a frame with an accommodation space, a magnetic circuit system and a vibration system accommodated in the frame. The vibration system includes a first vibration system and a second vibration system which are arranged with an interval. The first vibration system includes a first diaphragm and a first voice coil driving the first diaphragm, the second vibration system includes a second diaphragm and a second voice coil driving the second diaphragm to vibrate. The first diaphragm and the second diaphragm have the same vibration direction. The present disclosure has two vibration systems which break through the restriction of the height of the voice coils in the traditional structure and therefore further improve the product performance.
