Abstract: A pneumatic sounder and a control system thereof are disclosed. The pneumatic sounder comprises double magnets and a double-moving coil assembly. The double magnets comprise a first magnet and a second magnet, and the double-moving coil assembly comprises a first moving coil and a second moving coil. The first moving coil is disposed in a magnetic field of the first magnet, and the second moving coil is disposed in a magnetic field of the second magnet. The first moving coil and the second moving coil are connected to an electrical signal control system respectively, and a control system for the pneumatic sounder is also provided. The sounder greatly enhances adjustment efficiency of a cutting seam, reduces energy consumption for driving moving coils, guarantees services lives of the moving coils, and increases reliability of a system.
