Abstract: The present invention provides a gun vibration structure for somatosensory games, including a gun body, a trigger, a microswitch, a vibration unit, and a connector. The gun body includes a body portion and a grip portion. The body portion includes a housing space. The trigger is on the grip portion. The microswitch is on the grip portion and pressed by the trigger to be actuated. The vibration unit is in the housing space. The vibration unit includes an electromagnet and an actuation rod passing therethrough. When the electromagnet is electrified, the actuation rod reciprocates with respect to the electromagnet, ramming the body portion for generating the vibration in the housing space. The connector is on the grip portion and electrically connected with the microswitch and the electromagnet. The actuation rod is triggered to ram the body portion, generating a realistic vibration.
