Abstract

An improved earring-style hearing aid includes a tongue-shaped mold that fits along the bottom of the ear canal, leaving the ear canal substantially unfilled, and that delivers to the eardrum amplified sound that is received through a removably attachable connector from a combination microphone and amplification circuit that is attached to the ear lobe and that can be configured using one of many different covers to take the appearance of one of many different earrings.

Claims

1. A hearing aid comprising

a microphone for generating a signal;

an amplifier configurable to receive a signal for producing an amplified signal;

control means adapted to control said amplifier;

a receiver configured to receive said amplified signal and to generate a sound pressure signal;

a connector configurable to receive said amplified signal for conducting said sound pressure signal, said connector having an inner member and an outer member, said inner member being removably insertable into said outer member, said connector being able to conduct said sound pressure signal when said inner member is at least partially inserted into said outer member, said connector forming a breakaway nipple;

a conduit configurable to extend into the ear canal, said conduit configurable to receive said amplified signal from said connector for conducting said amplified signal to an area proximal to the eardrum;

a substantially flat circuit holder adapted to carry and electrically connect electronic components including said microphone, said amplifier, said control means, and a battery; and

a housing to contain said circuit holder and electronic components, adapted to be attached solely to an ear lobe, said housing having a female receptacle for housing the breakaway nipple and the outer member.

2. The hearing aid of claim 1, wherein the amplifier, when physically connected to the conduit, is able to be completely physically disconnected from the conduit by applying a force to the amplifier, said force being sufficient to remove the inner member from the outer member.

3. The hearing aid of claim 2, wherein the amplifier'"'"'s disconnectability from the conduit is sufficient to prevent the force applied to the amplifier from causing an injury proximal to the conduit.

4. The hearing aid of claim 1, wherein

the amplified signal comprises sound pressure waves;

and

the connector conducts sound pressure waves.

5. The hearing aid of claim 1 further comprising a pin configurable to attach the amplifier to the earlobe, the pin being at least vertically movable with respect to the amplifier.

6. The hearing aid of claim 1, wherein the conduit comprises a flexible plastic material.

7. The hearing aid of claim 1, wherein a substantial portion of the conduit is configurable to fit along the bottom of the ear canal, the ear canal thus being left substantially unfilled, the conduit substantially filling the ear canal only at the area proximal to the eardrum.

8. The hearing aid of claim 7, wherein the conduit comprises a tube for conducting the amplified signal to the area proximal to the eardrum.

9. The hearing aid of claim 1, wherein the inner member comprises a flexible plastic material.

10. The hearing aid of claim 1, wherein the outer member comprises a ridge that facilitates insertion of the inner member into the outer member.

11. A hearing aid comprising:

a microphone for generating a signal;

an amplifier;

configurable to receive a signal for producing an amplified signal;

control means adapted to control said amplifier;

a receiver configured to receive said amplified signal and to generate a sound pressure signal;

a sound-conducting connector configurable to receive said sound pressure signal for conducting said sound pressure signal, said connector having an inner member and an outer member, said inner member being removably insertable into the outer member and forming a breakaway nipple;

a conduit configurable to extend into the ear canal, said conduit configurable to receive said sound pressure signal from said connector for conducting said sound pressure signal to an area proximal to the eardrum;

a substantially flat circuit holder adapted to carry and electrically connect electronic components including said microphone, said amplifier, said control means, and a battery;

a housing to contain said circuit holder and electronic components, adapted to be attached to an ear lobe, said housing having a female receptacle for housing the inner and outer members; and

cosmetic jewelry attached to said housing, concealing said circuit holder.

12. The hearing aid of claim 11, wherein the cosmetic jewelry comprises a hearing aid cover for the amplifier, said cover comprising

an earring portion;

and

a connector portion for removably attaching said earring portion onto said amplifier.

13. The hearing aid of claim 12, wherein the amplifier further comprises a microphone opening and said cover further comprises a cover opening corresponding to said microphone opening.

14. The hearing aid of claim 12, wherein

the connector portion comprises threads for removably screwing the earring portion onto the amplifier;

and

the cover opening aligns with the microphone opening when the connector portion is fully screwed onto the amplifier.

15. The hearing aid of claim 12, wherein the cover comprises injection-molded plastic.

16. The hearing aid of claim 12, wherein the cover comprises a gemstone.

17. The hearing aid of claim 12, wherein the cover is selected from a group consisting of a plurality of covers, each said cover in said group having an appearance that is unique within the group.

18. The hearing aid of claim 17, wherein each cover in the group corresponds to an actual earring that matches the cover in appearance.
