Abstract: An air pressure massager includes at least one pressure field generating device. The pressure field generating device includes a chamber with at least one first opening, a connecting rod member connected to one end of the chamber, an eccentric member connected to the connecting rod member, a driving unit connected with the eccentric member, a control device configured to activate the drive unit, and an accessory. The first opening is configured to be placed on a portion of a human body. The driving unit drives the eccentric member to move to drive the connecting rod member to move, such that a volume of the chamber is changed to generate a pressure field for stimulating the human body. The pressure field generated in the chamber directly towards the portion of the human body. The pressure field is adjusted by a positive pressure mode and/or a negative pressure mode.
