The present invention relates to an arm unit of a massager, and more particularly, to an arm unit of a massager equipped with a sound wave vibration module. An object of the present invention is to provide a cancer unit of a massager capable of performing thermal massage while simultaneously transmitting a vibration according to a frequency (sound wave) desired by a user in a massager and expanding the body contact area of the arm unit contacting the user's body. . The present invention can have a massage effect using sound wave vibration by the user selecting one of various frequencies (sound wave) through the controller and transmitting it to the vibration unit, and outputting vibration according to the frequency (sound wave) received by the vibration unit. have. In addition, the present invention may have an effect of maximizing the massage efficiency by expanding the area in contact with the user's body by forming at least one vibration ball in contact with the user's body. In addition, according to the present invention, the at least one vibrating ball and the vibrating ball support formed between the head housings can be moved naturally without pain according to the bending of the user's body, and have an effect of expanding the massage area. In addition, the present invention is formed of a plate spring, a vibrating ball holder and a vibrating ball with a material whose thermal conductivity is higher than a predetermined reference value, thereby transferring heat generated by vibration and kinetic energy of the vibrating unit to the user's body to achieve a massage effect using heat Can have본 발명은 마사지기의 암 유닛에 관한 것으로 보다 상세하게는, 음파 진동 모듈이 구비된 마사지기의 암 유닛에 관한 것이다. 본 발명은 마사지기에서 사용자가 원하는 주파수(음파)에 따른 진동을 전달하고, 사용자의 신체에 접촉되는 암 유닛의 신체 접촉 면적 확대하는 것과 동시에 온열 마사지가 가능한 마사지기의 암 유닛을 제공하는 것을 목적으로 한다.본 발명은 사용자가 컨트롤러를 통해 다양한 주파수(음파) 중 하나를 선택하여 진동 유닛에 전달하고, 진동 유닛이 전달받은 주파수(음파)에 따른 진동을 출력하는 것에 의해 음파 진동을 이용한 마사지 효과를 가질 수 있다. 또한, 본 발명은 사용자의 신체에 접촉되는 진동볼을 적어도 1개 이상 형성하는 것에 의해 사용자의 신
