Abstract

Actuator systems for oral-based appliances utilizing transducers which are attached, adhered, or otherwise embedded into or upon a dental or oral appliance to form a hearing aid assembly. Such oral appliances may be a custom-made device which receives incoming sounds and transmits the processed sounds via a vibrating transducer element. The transducer element may utilize electromagnetic or piezoelectric transducer mechanisms and may be positioned directly along the dentition or along an oral appliance housing in various configurations.

Claims

1. An apparatus, comprising:

a housing engageable to at least one tooth without requiring anatomical modification of the at least one tooth;

a transducer configured to transmit vibrations to a surface of the at least one tooth; and

a movable mass coupled to the transducer.

2. The apparatus of claim 1 wherein the housing is removably securable to the at least one tooth.

3. The apparatus of claim 1 wherein the housing comprises an oral appliance that conforms to the at least one tooth.

4. The apparatus of claim 1 further comprising an electronic assembly disposed within or upon the housing and which is in communication with the transducer.

5. The apparatus of claim 1 further comprising a microphone in electrical communication with a processor.

6. The apparatus of claim 1 wherein the transducer is disposed along an outer surface of the housing.

7. The apparatus of claim 1 wherein the transducer is disposed along an inner surface of the housing against the surface of the at least one tooth.

8. The apparatus of claim 1, wherein the housing is engageable to the at least one tooth with an interference fit.

9. An apparatus, comprising:

a housing engageable to at least one tooth without requiring anatomical modification of the at least one tooth;

a transducer configured to transmit vibrations to a surface of the at least one tooth; and

a movable mass coupled to the transducer.

10. The apparatus of claim 9 wherein the housing is removably securable to the at least one tooth.

11. The apparatus of claim 9 wherein the housing comprises an oral appliance that conforms to the at least one tooth.

12. The apparatus of claim 9 further comprising an electronic assembly disposed within or upon the housing and which is in communication with the transducer.

13. The apparatus of claim 9 further comprising a microphone in electrical communication with a processor.

14. The apparatus of claim 9 wherein the transducer is disposed along an outer surface of the housing.

15. The apparatus of claim 9 wherein the transducer is disposed along an inner surface of the housing against the surface of the at least one tooth.

16. The apparatus of claim 9, wherein the housing is engageable to the at least one tooth with an interference fit.
