Abstract
A bone conduction acoustic transmission device according to the present invention is provided with a first magnetic body to be placed in contact with or to be embedded in the head of a living body beforehand, and a coil unit provided separately from the first magnetic body. The coil unit has a coil configured using a predetermined casing that can be mounted on the first magnetic body and a second magnetic body which is provided in a predetermined position of the casing and does not vibrate due to the coil, and the first magnetic body vibrates as a result of applying an acoustic signal to the coil with the coil unit mounted on the head.
Claims10
A bone conduction acoustic transmission device, comprising:
- a first magnetic body placeable to be in contact with or embeddable in a head of a living body;
- a coil unit separate from the first magnetic body, wherein
- the coil unit includes:
- a casing mountable on the first magnetic body;
- a coil wound around the casing;
- and
- a second magnetic body inside the casing, wherein the second magnetic body is configured not to vibrate due to the coil, and
- the first magnetic body is configured to vibrate based on an acoustic signal applied to the coil with the coil unit mounted on the head;
- and
- a vibration damping member that protrudes from a bottom surface of the casing, wherein
- the bottom surface of the casing is on a side opposite the head,
- the vibration damping member is configured to enclose sides of the first magnetic body with the coil unit is mounted on the head, and
- a height at which the vibration damping member protrudes from the bottom surface is higher than a height of the first magnetic body.
