Abstract: A printed circuit board (PCB) configured to be included in a massage applicator. The PCB including a clock module configured to provide at least one clock signal, a controller configured to receive the at least one clock signal from the clock module and control a motor of the massage applicator to provide a plurality of vibration levels, and an optical sensor configured to capture a rotation of a swivel dial indicating a desired vibration level of the plurality of vibration levels.

Abstract: A massage device includes a main body having a gripping section adapted to be held by a user, a massaging head, and an actuator configured to effect a reciprocating movement of the massaging head relative to the gripping section. The massaging head includes a negative pressure cavity connected to the suction pump and conveying negative pressure to an insert having a flexible part with contacting edge for contacting a body surface receiving therapeutic massage, and a rigid part for coupling the insert to the massaging head. Optionally, the flexible part collapses longitudinally in response to vacuum pressure and forms a more rigid reciprocal force transmission path from the massaging head to the contacting edge.
