MICROPHONE PLACEMENT FOR ORAL APPLICATIONS
First Claim
1. A system for receiving audio signals within a mouth of a user, comprising:
- a first transducer disposed within or upon a first housing and in vibratory communication with a surface of at least a first tooth;
a first microphone disposed within or upon the first housing such that the first microphone is acoustically coupled to an inner surface of the user'"'"'s cheek;
a second microphone disposed within or upon the first housing and adapted to receive an audio signal from the user'"'"'s own voice; and
a first processor disposed within or upon the first housing and in electrical communication with the first transducer, first microphone, and second microphone.

Abstract
Microphone placement for oral applications 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 which can enhance and/or optimize received audio signals for vibrational conduction to the user. Received audio signals may be processed to cancel acoustic echo such that undesired sounds received by one or more intra-buccal and/or extra-buccal microphones are eliminated or mitigated. Multiple microphones may be positioned throughout the user'"'"'s mouth to enhance reception of audio signals from outside sources as well as from the user'"'"'s own voice. For instance, one or more microphones may be placed in contact with the inner surface of the user'"'"'s cheeks to detect outside audio signals as well as in direct contact with the user'"'"'s tooth or teeth to receive the user'"'"'s voice through vibrational detection.

8. A method for receiving audio signals within a mouth of a user, comprising:
-
detecting a first audio signal from outside the mouth via a first microphone acoustically coupled to an inner surface of the user'"'"'s cheek; detecting a second audio signal from inside the mouth via a second microphone; and processing the first and second audio signals to obtain a combined audio signal for transmission.
