## Abstract

An intra-oral appliance for transmitting sound via bone conduction and optimized for comfort, safety, speech intelligibility, eating and drinking and extended wear by the user including an actuator to provide bone conduction sound transmission; a transceiver coupled to the actuator to cause the actuator to generate sound; and a first chamber containing the actuator and the transceiver, said first chamber adapted to be coupled to one or more teeth of the user.

## Claims

### Claim 1

An intraoral appliance for sound transmission comprising an intra-oral bone conduction sound transmission device securable to one or more teeth without requiring modification of the one or more teeth,
wherein the intra-oral bone conduction sound transmission device comprises a movable mass securable to the one or more teeth with a spring, and
wherein the spring is configured to provide a clamping force that acts on a lingual side and buccal side of one or more of the one or more teeth.

### Claim 2 (depends on 1)

The appliance of claim 1, wherein the one or more teeth comprises a distal-most molar of a user, and wherein the spring is configured to extend around a distal end of the distal-most molar.

### Claim 3 (depends on 1)

The appliance of claim 1, wherein the intra-oral bone conduction sound transmission device comprises at least one of an actuatable transducer and a movable mass.

### Claim 4

An intraoral appliance for sound transmission, comprising:
a wearable housing having a vibrator configured to cause bone conduction sound transmission, wherein the wearable housing is securable to one or more teeth without requiring modification of the one or more teeth,
wherein the vibrator is securable to the one or more teeth with a spring, and
wherein the spring is configured to provide a clamping force that acts on a lingual side and a buccal side of one or more of the one or more teeth.

### Claim 5 (depends on 4)

The appliance of claim 4, wherein the one or more teeth comprises a distal-most molar of a user, and wherein the spring is configured to extend around a distal end of the distal-most molar.

### Claim 6 (depends on 4)

The appliance of claim 4, wherein the vibrator comprises at least one of an actuatable transducer and a movable mass.

### Claim 7 (depends on 4)

The appliance of claim 4, wherein the vibrator is securable to the one or more teeth with an interference fit.

### Claim 8

An intraoral appliance for sound transmission, comprising:
a moveable mass securable to one or more teeth, wherein the moveable mass is configured to cause bone conduction sound transmission,
wherein the movable mass is securable to one or more of the one or more teeth with a spring, and
wherein the spring is configured to provide a clamping force that acts on a lingual side and a buccal side of one or more of the one or more teeth.

### Claim 9 (depends on 8)

The appliance of claim 8, wherein the one or more teeth comprises a distal-most molar of a user, and wherein the spring is configured to extend around a distal end of the distal-most molar.

### Claim 10 (depends on 8)

The appliance of claim 8, wherein the moveable mass is positioned within or attached to a housing shaped for intra-oral wear.

### Claim 11 (depends on 8)

The appliance of claim 8, wherein the movable mass is a rechargeable energy source.

### Claim 12 (depends on 8)

The appliance of claim 8, wherein the movable mass is securable to the one or more teeth without requiring modification of the one or more teeth.

### Claim 13 (depends on 8)

The appliance of claim 8, wherein the movable mass is securable to the one or more teeth with an interference fit.

### Claim 14 (depends on 13)

The appliance of claim 13, wherein the interference fit is produced without requiring modification of the one or more teeth before wearing the appliance.
