The invention relates to a gas pressure wave generator for a regenerative type refrigerator. The gas pressure wave generator comprises motors, a corrugated pipe component and a fixed housing. The motors and the corrugated pipe component are arranged in the fixed housing. The motors comprise stator components, mover components and soft magnets. The corrugated pipe component comprises a corrugated pipe, a base and a blind plate. The base and the blind plate are fixedly connected with two ends of the corrugated pipe respectively. The base is arranged in the corrugated pipe and provided with an air exhausting outlet. The base, the blind plate and the inner wall of the corrugated pipe are combined to form a sealed compressing chamber. One end, fixed to the base, of the corrugated pipe is fixedly connected with the stator components, and one end, fixed to the blind plate, of the corrugated pipe is fixedly connected with the mover components. The end, fixed with the mover components, of the corrugated pipe is driven by the mover components to do reciprocating motion along the axial direction of the corrugated pipe, allowing pressure surge to occur to the filled gas. According to the technical scheme, the gas pressure wave generator is free of a compressing piston and a compressing cylinder and overcomes the defects of difficult production, low compressing efficiency and requirement on high quantity of the gas of the conventional compressor.
