The invention relates to the technical field of massagers, aims to solve the problem of how to reduce
massage noise, and provides a pressure field generating device and a massager. The pressure field generating device comprises a pressure generating piece and a magnetic driving
assembly. The pressure generating piece comprises a cavity, and the cavity is provided with an opening for being placed on a body part. The magnetic driving
assembly comprises a first magnetic part and a second magnetic part, the first magnetic part is fixedly connected with the cavity, and
magnetic poles of the first magnetic part and
magnetic poles of the second magnetic part correspond to each other in the first direction and are arranged at intervals. The magnetic pole of at least one of the first magnetic piece and the second magnetic piece can be changed so that the first magnetic piece can move in the first direction, the volume of the cavity can be changed, and an irritant pressure field can be generated at the opening. The first magnetic part is driven by magnetic force, so that the first magnetic part is not in contact with the second magnetic part,
noise generated by mutual friction of all parts during movement is reduced, and the effect of reducing
noise generated by
massage of the pressure field generating device is achieved.
