Abstract
Disclosed is a sound generator, including a bracket, and a vibration system and a magnetic circuit system. The vibration system includes a first vibration diaphragm, s a second vibration diaphragm, a first voice coil driving the first vibration diaphragm, and a second voice coil driving the second vibration diaphragm. The magnetic circuit system includes an iron core, a magnet assembly, and a magnetic frame. The first voice coil is disposed between the magnetic frame and the magnet assembly, and the second voice coil is disposed between the magnet assembly and the iron core. Therefore, two magnetic circuit structures are provided in the same magnetic frame space and drive the first vibration diaphragm and the second vibration diaphragm to vibrate and generate sound in different directions respectively, which improves the utilization efficiency of the magnetic circuit system while saving space, thereby improving the sound generation performance of the sound generator.
