Intelligent shawl massager(Shoulder Massagers) can be divided into three parts: control component, electromagnetic hammer component and shawl coat. Intelligent Shoulder Massagers is divided into parts, mainly composed of iron core, coil, vibration spring and massage head.
When the coil on the fixed iron core is connected to AC, the alternating magnetic field is generated. Under the action of the magnetic field force and the vibration spring sheet, the massage head vibrates repeatedly. The vibration frequency is generally 100 Hz and the input power is 10 – 15W. There are two ways to change the vibration intensity, one is to change the gap or current intensity of the iron core, the other is to change the frequency of vibration.
