Abstract

Methods and apparatus for transmitting vibrations via an electronic and/or transducer assembly through a tooth or teeth are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.

Claims

1. A bone conduction apparatus, comprising:

a housing having a first vibrator configured to transmit vibrations to one or more first teeth, wherein the housing is comprised of a shape memory material having a pre-formed unbiased configuration and a deformed configuration whereby the housing is securable onto the one or more first teeth in the deformed configuration, and wherein when the housing is in the deformed configuration, the housing is biased to press the first vibrator against the one or more first teeth.

2. The apparatus of claim 1, wherein the housing is securable to the one or more teeth without requiring modification of the one or more teeth.

3. The apparatus of claim 1, wherein the housing has an occlusal opening.

4. The apparatus of claim 1, further comprising a microphone in communication with the vibrator.

5. The apparatus of claim 1, further comprising a second vibrator configured to transmit vibrations to one or more second teeth.

6. The apparatus of claim 5, wherein the one or more first teeth are right teeth and the one or more second teeth are left teeth.

7. The apparatus of claim 1, wherein the oral appliance is fabricated via a three-dimensional printing process.

8. A bone conduction apparatus, comprising:

a housing having a first vibrator configured to transmit vibrations to one or more first teeth, wherein the housing has a non-deformed configuration and a deformed configuration, wherein the housing changes from the non-deformed configuration to the deformed configuration when the housing is secured to the one or more first teeth, and wherein when the housing is in the deformed configuration, the housing is biased to press the first vibrator against the one or more first teeth.

9. The apparatus of claim 8, wherein the housing is securable to the one or more teeth without requiring modification of the one or more teeth.

10. The apparatus of claim 8, wherein the housing has an occlusal opening.

11. The apparatus of claim 8, further comprising a microphone in communication with the vibrator.

12. The apparatus of claim 8, further comprising a second vibrator configured to transmit vibrations to one or more second teeth.

13. The apparatus of claim 12, wherein the one or more first teeth are right teeth and the one or more second teeth are left teeth.

14. The apparatus of claim 8, wherein the oral appliance is fabricated via a three-dimensional printing process.

15. A bone conduction apparatus, comprising:

a housing having a vibrator configured to transmit vibrations to one or more teeth, wherein the housing has a first configuration and a second configuration different from the first configuration, wherein the housing has the first configuration before the housing is placed upon or against the one or more teeth and has the second configuration after the housing is placed upon or against the one or more teeth, and wherein when the housing is in the second configuration, the housing has an occlusal opening, and when the housing is in the second configuration, the housing is biased to press the first vibrator against the one or more teeth.

16. The apparatus of claim 15, wherein the housing has a first shape in the first configuration and a second shape in the second configuration, and wherein the first and second shapes are different from one another.

17. The apparatus of claim 15, wherein the housing has a first size in the first configuration and a second size in the second configuration, and wherein the first and second sizes are different from one another.

18. The apparatus of claim 15, wherein the housing is securable to the one or more teeth without requiring modification of the one or more teeth.

19. The apparatus of claim 15, further comprising a microphone in communication with the vibrator.

20. The apparatus of claim 15, and wherein when the housing is in the first configuration, the housing has the occlusal opening.
