Vibration generation device

A vibration generation device comprising:

• a vibration generator configured to generate a vibration, the vibration generator including an exciter in which each of a magnetic circuit, a voice coil bobbin, and a frame have a rotating body shape, and each of the magnetic circuit, the voice coil bobbin, and the frame is assembled coaxially with a central axis of the frame;
• and
• a vibration transmission member having a vehicle-side fixed part to be fixed to a glass surface of a windshield of a vehicle or to a frame for fixing the upper end portion of the windshield when in use, the vibration transmission member being configured to transmit to the vehicle the vibration generated by the vibration generator,
• wherein the vehicle-side fixed part is provided within a range of the vibration generator, as viewed from a vibration direction of the vibration generator,
• the vibration transmission member includes the vehicle-side fixed part that is installed at a center of the vehicle width of the vehicle when in use;
• an extension part horizontally extending in a linear shape in a direction of being spaced apart from the vehicle-side fixed part toward a vehicle rear side when the extension part is fixed to the vehicle, and having a tip serving as a free end;
• and a vibration generator fixing part which is provided at the tip serving as the free end of the extension part, and to which the exciter is fixed, wherein
• when the exciter is fixed to the vehicle, the exciter is fixed in a posture such that the vibration direction, that is, the central axis of the frame is perpendicular to a fixed surface of the vibration generator fixing part, the fixed surface is formed by bending an end portion of the extension part at 90 degrees, so that the central axis of the exciter is parallel to the extension part, and the exciter is supported on the extension part in a cantilever manner at a position spaced apart from the vehicle-side fixed part toward the vehicle rear side in a state where the vibration direction is oriented horizontally.
