A pneumatic sounder and a control system thereof. The pneumatic sounder comprises double magnets and a double-moving coil assembly. The double magnets comprise a first magnet (3) and a second magnet (6). The double-moving coil assembly comprises a first moving coil (4) and a second moving coil (5). The first moving coil (4) is disposed in a magnetic field of the first magnet (3), and the second moving coil (5) is disposed in a magnetic field of the second magnet (6). The first moving coil (4) and the second moving coil (5) are connected to an electric signal control system separately. The control system comprises: a feedback coil, disposed on the double-moving coil assembly and used for generating a feedback signal; a signal conditioner, used for receiving the feedback signal sent by the feedback coil, and adjusting amplitude parameters of signals that are from a signal source and to be sent to the moving coils; and a phase conditioner, used for receiving the feedback signal sent by the feedback coil, and adjusting phase parameters of the signals that are from the signal source and to be sent to the moving coils. The sounder greatly improves the adjustment efficiency of a cutting seam, reduces the driving energy consumption of moving coils, guarantees the service lives of the moving coils, and improves the reliability of a system. |
