Abstract

An ear tip apparatus for use with a hearing device is provided and comprises a malleable structure. The malleable structure is sized and configured for placement in an ear canal of a user. The malleable structure is deformable to allow an adjustable venting of the ear canal, thereby minimizing the occlusion effect. Methodology for adjusting a degree of venting of the ear canal is also provided, including the automatic adjustments. Adjusting the degree of venting may be done in response to one or more of detected feedback or an environmental cue.

Claims

1. An ear tip apparatus for use with a hearing device, the ear tip comprising:

a malleable structure sized and configured for placement in an ear canal of a user, the malleable structure having a cross-section shaped to define at least one channel between an inner wall of the ear canal and an outer surface of the malleable structure for venting of the ear canal;

an output transducer positioned in the malleable structure,

wherein the malleable structure is deformable to adjust the cross-section thereof so as to vary a size of the at least one channel to adjust a degree of venting provided by the at least one channel; and

an actuator coupled to the malleable structure and operable to cause the malleable structure to deform,

wherein the actuator comprises a slider configured for translation and/or rotation relative to the malleable structure.

2. The apparatus of claim 1, wherein the slider comprises one or more threads to facilitate rotation relative to the malleable structure.

3. The apparatus of claim 1, wherein translating the slider toward the malleable structure deforms the malleable structure to increase the size of the at least one channel to reduce the degree of venting provided by the at least one channel.

4. The apparatus of claim 1, wherein the actuator further comprises an elongate element coupled to the malleable structure and the slider, wherein the malleable structure is disposed over the elongate element and the slider is translatable over the elongate element.

5. The apparatus of claim 1, wherein the actuator is configured to vary the degree of venting provided by the at least one channel in response to one or more of detected feedback or an environmental cue.

6. The apparatus of claim 1, wherein the malleable structure is deformable between a low cross-sectional area configuration and a high cross-sectional area configuration, the at least one channel providing more venting when the malleable structure is in the low cross-sectional area configuration than when in the high cross-sectional area configuration.

7. The apparatus of claim 1, wherein the malleable structure has one or more of a Y-shaped, X-shaped, or cross-shaped cross-section.

8. The apparatus of claim 1, wherein the malleable structure comprises a gel.

9. The apparatus of claim 1, wherein the malleable structure comprises a fluid-filled bladder, the fluid-filled bladder comprising a bladder wall and a bladder fluid, and wherein the bladder wall comprising one or more of a stiff plastic or an elastomeric material.

10. A method for reducing occlusion in a hearing device placed in an ear canal of a user, the method comprising:

deforming a malleable structure placed in the ear canal to vary a size of at least one channel to adjust a degree of venting provided by the at least one channel,

wherein the malleable structure is sized and configured for placement in the ear canal and has a cross-section shaped to define the at least one channel between the inner wall of the ear canal and an outer surface of the malleable structure,

wherein deforming the malleable structure comprises one or more of translating or rotating a slider relative to the malleable structure; and

emitting an optical signal from the malleable structure.

11. The method of claim 10, wherein the slider is translated or rotated over an element, wherein one or more of the slider or the malleable structure is disposed over the element.

12. The method of claim 10, wherein the malleable structure comprises a gel.

13. The method of claim 10, further comprising adjusting the degree of venting in response to one or more of detected feedback or an environmental cue.

14. A method for reducing occlusion in a hearing device placed in an ear canal of a user, the method comprising:

deforming a malleable structure placed in the ear canal to vary a size of at least one channel to adjust a degree of venting provided by the at least one channel,

wherein the malleable structure is sized and configured for placement in the ear canal and has a cross-section shaped to define the at least one channel between the inner wall of the ear canal and an outer surface of the malleable structure;

adjusting the degree of venting in response to one or more of detected feedback or an environmental cue; and

emitting an optical signal from the malleable structure.
