Balls in massage bed

摘要

The balls are located on the points of spring-loaded work units, which in turn are located in a guide rail and can be fixed. The balls are located tightly against one another and are set in vibration by changing pressure. The inner part of the work unit is equipped with a coil through which alternating current flows, which when switched on produces a force. This force acts directly on the ball locating on the human body. The force and time duration can be regulated.
