Patent ID: 8464586

Claim:
A vibration wave output instrument, comprising: a base; a vibration device for sending vibration waves to a target region; a pneumatic cylinder unit for driving the vibration device to press on the target region; and a position mechanism movably installed on the base, for carrying both the pneumatic cylinder unit and the vibration device to the target region, the position mechanism comprising a movable carrier, and the movable carrier includes a container containing both the pneumatic cylinder unit and the vibration device therein, the container having an opening, wherein when the vibration device is pressed by the pneumatic cylinder unit, the vibration device extends outwards from the opening to the target region, a board linearly movably disposed in the container and arranged between the pneumatic cylinder unit and the vibration device, wherein one surface of the board couples to the vibration device, and another surface of the board is pressed by the pneumatic cylinder unit, and an elastic element disposed in the container, having two opposite ends respectively coupling with the board and the container.
