Dental bone conduction hearing appliance
View Patent ↗An intra-oral hearing appliance includes 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 without contacting the occlusal surfaces of the one or more teeth.
1. An intra-oral appliance for transmitting vibrations, comprising:
a. an actuator to provide bone conduction sound transmission;
b. a transceiver in communication with the actuator to cause the actuator to generate sound; and
c. a first chamber containing the actuator and the transceiver, said first chamber adapted to be coupled to one or more teeth without contacting occlusal surface(s) of the one or more teeth by producing an interference fit between the first chamber and at least two surfaces of the one or more teeth.
2. The appliance of claim 1 , comprising an actuator driver or amplifier coupled to the actuator.
3. The appliance of claim 1 , comprising a second chamber to house a power source to drive the actuator and the transceiver.
4. The appliance of claim 3 , comprising a bridge coupling the first and second chambers.
5. The appliance of claim 4 , wherein the bridge comprises a thickness of about two millimeters or less.
6. The appliance of claim 4 , wherein the bridge comprises one of: a wired frame, a polymeric material, a combination of polymeric material and a wired frame.
7. The appliance of claim 1 , comprising a mass coupled to the actuator.
8. The appliance of claim 7 , wherein the mass comprises one of a weight, a battery, an electronics module.
9. The appliance of claim 1 , wherein the actuator comprises a piezoelectric transducer.
10. The appliance of claim 1 , wherein the actuator comprises a rectangular beam bender.
11. The appliance of claim 1 , comprising one or more ceramic or alumina stands coupled to the actuator.
12. The appliance of claim 1 , comprising a compressible material coupled to the actuator.
13. The appliance of claim 12 , comprising a non compressible material covering the actuator and the compressible material.
14. The appliance of claim 1 , comprising a rechargeable power source coupled to the transceiver and the actuator.
15. The appliance of claim 14 , comprising an inductive charger coupled to the battery.
16. The appliance of claim 1 , wherein the chamber comprises a custom oral device.
17. The appliance of claim 1 , comprising a pre-built housing for the actuator.
18. The appliance of claim 17 , wherein the pre-built housing comprises an arm and one or more bottom contacts, the arm and the contacts adapted to bias a mass against a tooth.
19. The appliance of claim 1 , wherein the chamber comprises a thickness of about six millimeter or less.
20. The appliance of claim 1 , wherein the chamber comprises a length of about twenty millimeters or less.
21. The appliance of claim 1 , wherein the chamber comprises a width of about fifteen millimeters or less.
22. The appliance of claim 1 , wherein said first chamber is coupled to at least one side surface of the one or more teeth such that the first chamber's non-contact with dental occlusal surface(s) facilitates continuous flushing of oral fluids to prevent trapping of food or drink.
