Abstract: To design an electronic sleep massager that can perform massage and sleep aid at the same time.It is powered by a 9 V battery,and a multivibrator is composed of a 555 timer as the core to generate an oscillation signal.The 0～180 V continuously adjustable electrical pulse was output to the massage electrode through the step-up transformer,and the low-frequency sound signal was output through the speaker to achieve massage and sleep assistance.The electronic sleep massager has simple design and excellent performance,and uses sound hypnosis and acupressure massage at the same time,which can achieve relatively good hypnosis and fatigue relief effects,and is a small electronic health care product suitable for home use,and has certain promotion and application value.
