Abstract
Provided is a vibration generator that even if a vibration is generated in the seat surface of a seat, allows a seated person to easily feel the vibration. A vibration generator (1) includes a vibration transmission member (10) and an exciter (20). The vibration transmission member (10) is disposed in a seat surface (2a) of a seat (2) so as to extend in the horizontal direction of the seat surface (2a) and is able to transmit a vibration in the extending direction. The exciter (20) is able to transmit a vibration to the vibration transmission member (10) in the extending direction of the vibration transmission member (10).
Claims5
A vibration generator comprising:
- a vibration transmission member disposed in a seat beneath a seat surface of the seat so as to extend longitudinally in a horizontal direction of the seat surface and configured to transmit a vibration in an extending direction of the vibration transmission member in which the vibration transmission member extends longitudinally;
- and
- an exciter configured to vibrate in the extending direction and configured to transmit a vibration to the vibration transmission member in the extending direction;
- wherein the exciter comprises:
- a frame attached to one end of the vibration transmission member in the extending direction;
- a cylindrical bobbin connected to the frame;
- a voice coil wound around the cylindrical bobbin;
- a permanent magnet surrounded by the cylindrical bobbin;
- and
- a yoke supporting the permanent magnet, and
- wherein the yoke is configured to approach and separate from the frame in the extending direction so that the cylindrical bobbin vibrates in the extending direction.
