Working Principle Of Neck And Shoulder Massager

The electromagnetic massager is mainly composed of an iron core (including a fixed iron core and a movable iron core), a coil, a vibrating spring piece and a massage head. When the coil on the fixed iron core is connected to alternating current, an alternating magnetic field is generated, and the massage head vibrates repeatedly under the action of the magnetic field force and the vibrating spring piece. The vibration frequency is generally 100Hz, and the input power is 10-15W. The method to change the vibration intensity is to change the iron core gap or current intensity, and to change the vibration frequency.
