## Abstract

A sound damping device includes a sound damper and a support member. The sound damper includes a contact surface configured to contact a vibration member and includes a through-hole having a first opening formed on the contact surface. The support member is coupled to the sound damper to support the sound damper and cause the vibration member and the contact surface to come into contact with each other. The support member includes an air hole that is connected to the through-hole of the sound damper and that penetrates through the support member.

## Claims

### Claim 1

A sound damping device comprising:
a sound damper that includes a contact surface configured to contact with a vibration member and that includes a through-hole having a first opening formed on the contact surface; and
a support member coupled to the sound damper to support the sound damper and cause the vibration member and the contact surface to come into contact with each other, the support member including an air hole that is connected to the through-hole of the sound damper and that penetrates through the support member.

### Claim 2 (depends on 1)

The sound damping device according to claim 1, wherein
the sound damper further includes a supporting surface on an opposite side of the contact surface, and the through-hole further has a second opening formed on the supporting surface, and
the air hole communicates with the through-hole via the second opening.

### Claim 3 (depends on 1)

The sound damping device according to claim 1, wherein
the sound damper has an annular shape.

### Claim 4 (depends on 1)

The sound damping device according to claim 1, wherein
a position at which the sound damper is coupled to the support member is adjustable.

### Claim 5

A sound damping method comprising:
causing a vibration member and a sound damper to come into contact with each other:
transmitting air vibrations generated by vibration of the vibration member via a through-hole formed in the sound damper; and
transmitting the air vibrations via an air hole that is formed in a support member coupled to the sound damper to support the sound damper and that penetrates through the support member.

### Claim 6

A vibration detection device comprising:
a sound damper that includes a contact surface configured to contact with a vibration member and that includes a through-hole having a first opening formed on the contact surface; and
a support member coupled to the sound damper to support the sound damper and cause the vibration member and the contact surface to come into contact with each other, the support member including an air hole that is connected to the through-hole of the sound damper and that penetrates through the support member,
the sound damper further including a vibration detector configured to detect vibration.

### Claim 7 (depends on 6)

The vibration detection device according to claim 6, wherein
the sound damper further includes a supporting surface on an opposite side of the contact surface, and the through-hole further has a second opening formed on the supporting surface, and
the air hole communicates with the through-hole via the second opening.

### Claim 8 (depends on 6)

The vibration detection device according to claim 6, wherein
the sound damper includes a first sound damper, a second sound damper, and a sensor board to which the vibration detector is coupled,
the first sound damper has a first through-hole,
the second sound damper has a second through-hole, and
the sensor board is sandwiched between the first sound damper and the second sound damper and has a hole that communicates with the first through-hole and the second through-hole.
