[0026] In this embodiment, the noise reduction device of the fascia gun includes a housing 1, and a control unit and a motion unit are contained in the housing 1. The control unit can control the motion unit to perform reciprocating motion, so that the motion unit massages the human body. The existing fascia gun also has a control unit and a motion unit, but its noise reduction method is mainly achieved by using an oil-containing bearing (commonly known as a copper sleeve) in combination with a metal piston and shock-absorbing silica gel, but its manufacturing cost is high, the economic benefit is poor, and a large amount of resources are consumed. However, the noise reduction device in this embodiment eliminates the use of oil-containing bearings (copper sleeves) and metal pistons, and simplifies the structural design and the use of materials by arranging a noise reduction unit on both sides of the connecting rod piston 5, so that the use of materials is more economical and easier to assemble, while achieving the purpose of noise reduction and shock absorption, and improving economic benefits.
