Abstract

The invention relates to a pneumatic sounder and its control system. The pneumatic sounder includes a double magnet and a double moving coil assembly, the double magnet includes a first magnet and a second magnet, and the double moving coil assembly includes a first moving coil and a second moving coil , the first moving coil is set in the magnetic field of the first magnet, the second moving coil is set in the magnetic field of the second magnet, and the first moving coil and the second moving coil are respectively connected with the electric signal control system. Its control system includes a feedback coil set on the double moving coil assembly, which is used to generate a feedback signal; a signal conditioner, which is used to receive the feedback signal sent by the feedback coil, and adjust the amplitude of the signal from the signal source and sent to the moving coil at the same time. Value parameter; phase conditioner, used to accept the feedback signal sent by the feedback coil, and adjust the phase parameter of the signal from the signal source and sent to the moving coil at the same time. The invention greatly improves the adjustment efficiency of the cutting seam, reduces the energy consumption of the driving moving coil, ensures the service life of the moving coil, and improves the reliability of the system.

Description

technical field [0001] The invention belongs to the technical field of pneumatic sound generation, and in particular relates to a pneumatic sounder and a control system thereof. Background technique [0002] Related studies have shown that electrical signals are used to control airflow to generate high-intensity noise, and high-intensity sound generators can generate sine, random, and composite traveling waves within a given frequency range. It can be used as a sound source for traveling wave tubes, reverberation chambers, and free-field acoustic experiments. The high sound intensity sounder can simulate the noise and ultrasonic waves generated by the engines of aircraft, rockets and other aircraft in flight. [0003] Patent application CN2694423Y discloses a pneumatic sounder capable of generating high-intensity noise, which mainly includes a magnet, a dynamic and static ring assembly, an air inlet and an air outlet. Among them, the moving coil is connected by the electri...
