An improved impact massager includes two impact force modules and a main circuit board in a chassis. An electromagnetic component and a cushioning element are coaxially provided in a heat sink of each impact force module. A drive rod of a drive component group is connected to an impact rod. A coupler of a transmission assembly is connected to the coupling seat with an oscillating coil provided therein and electrically connected with the main circuit board. When the oscillating coil and the magnetic core ring are coaxially positioned and displaced with respect to each other, the magnetic core ring does not interact with the oscillating coil, no current is generated by the oscillating coil and the main circuit board is in a power-off state, such that no power is transmitted to the electromagnetic component and motions are inhibited under no-load condition.
