Abstract
(EN)
The present utility model provides a sound generating device, comprising a cone frame, as well as a magnetic circuit system and a vibration system that are fixed on the cone frame. The vibration system comprises a sound membrane and a voice coil driving the sound membrane to vibrate. The sound membrane comprises a diaphragm and a dome fixed on the diaphragm. The voice coil comprises a first surface close to the sound membrane and a second surface away from the sound membrane. The outer diameter of the voice coil on the first surface is a first outer diameter, and the outer diameter of the voice coil on the second surface is a second outer diameter. The first outer diameter is smaller than the second outer diameter, and the outer diameter of the dome is greater than or equal to the second outer diameter. The sound generating device provided by the utility model has a good acoustic performance.
