Abstract
A vibration generation device includes a plunger and a solenoid. The plunger includes a weight portion, a first biasing portion extending from the weight portion along a first direction and a second biasing portion extending from the weight portion along a second direction opposite to the first direction. The solenoid includes a first solenoid that is disposed so as to surround a part of the first biasing portion and operates the plunger in the first direction, and a second solenoid that is disposed so as to surround a part of the second biasing portion and operates the plunger in the second direction. The first solenoid and the second solenoid have a fixing portion for a vibration target, and the weight portion reciprocates between the first solenoid and the second solenoid to vibrate the vibration target.
