Disclosed is a sound generator, including a bracket, a magnetic circuit system, a first vibration system, and a second vibration system. The bracket has a first opening and a second opening that face opposite directions. The magnetic circuit system is used for driving the first vibration system and the second vibration system to generate sound in different directions. The first vibration system includes a first voice coil, the second vibration system includes a second voice coil, and the magnetic circuit system includes a first magnet, a second magnet, and a third magnet. The first voice coil is sleeved on outer sides of the first magnet and the second magnet simultaneously, and the second voice coil is sleeved on outer sides of the second magnet and the third magnet simultaneously. In the present invention, the loudness of sound generated by the sound generator may be improved.
