Abstract

An ear tip piece device made of resilient material dimensioned for fitting the ear canal of a wearer, having a solid portion, a reversibly compressible portion, a channel and a sound attenuating element positioned inside the channel for attenuating sound being transmitted to the ear. In one embodiment, the ear tip piece is asymmetrical due to a bend.

Claims (37)

1. An ear tip piece for insertion in an ear canal to attenuate sound being transmitted to the ear, comprising:

a first end including a solid portion that is sized and shaped to be inserted into and align the ear tip piece in the ear canal;

a second end including a reversibly compressible portion formed by a hollow having flexible walls that adapt to the shape of the ear canal to create a seal;

a channel formed in the solid portion that is open to the hollow for transmitting sound to the ear; and

a sound attenuator positioned inside the channel for attenuating sound being transmitted to the ear.

2. The ear tip piece of claim 1 , further comprising a bend between the first end and second end, the bend comprising an interior curve and an opposite curve that are sized and shaped to facilitate insertion of the ear tip piece at or near a first or second bend of the ear canal.

3. The ear tip piece of claim 1 , further comprising a coupler inserted into the channel for retaining the sound attenuator.

4. The ear tip piece of claim 1 , wherein the sound attenuator is a filter.

5. The ear tip piece of claim 1 , wherein the sound attenuator is a plug.

6. The ear tip piece of claim 3 , wherein a wax basket is fit inside the coupler for preventing the buildup of ear wax.

7. The ear tip piece of claim 3 , wherein the coupler includes an extraction device to facilitate removal of the ear tip piece from the ear canal.

8. The ear tip piece of claim 3 , wherein the coupler includes an insertion device to facilitate placement of the ear tip piece inside the ear canal.

9. The ear tip piece of claim 1 , further comprising a cavity in the solid portion of the first end adjacent to the channel.

10. The ear tip piece of claim 2 , wherein the bend forms an angle in a range from about 57° to about 87°.

11. The ear tip piece of claim 1 , wherein the first and second ends are sized and shaped to be inserted in the ear canal such that no portion of the ear tip piece protrudes outside of the ear canal.

12. The ear tip piece of claim 2 , wherein the interior curve has an angle of approximately 72°±/−15°.

13. The ear tip piece of claim 2 , wherein the side of ear tip piece having the interior curve has a length of approximately 0.48 inches and the side of the ear tip piece having the opposite curve has a length of about 0.59 inches.

14. The ear tip piece of claim 2 , wherein the side of ear tip piece having the interior curve has a length of approximately 0.49 inches and the side of the ear tip piece having the opposite curve has a length of about 0.60 inches.

15. An ear tip piece for insertion in an ear canal to attenuate sound being transmitted to the ear, comprising:

a first end including a solid portion that is sized and shaped to be inserted into and align the ear tip piece in the ear canal;

a second end including a reversibly compressible portion formed by a hollow having flexible walls that adapt to the shape of the ear canal to create a seal;

a bend between the first end and second end, the bend comprising an interior curve and an opposite curve that are sized and shaped to facilitate insertion of the ear tip piece at or near a second bend of the ear canal;

a channel formed in the solid portion that is open to the hollow for transmitting sound to the ear; and

a sound attenuator positioned in the channel to attenuate sound transmitted to the ear; and

a coupler inserted into the channel for retaining the sound attenuator in the ear tip piece.

16. The ear tip piece of claim 1 , wherein the sound attenuator is a damper.

17. The ear tip piece of claim 1 , further comprising an extraction device.

18. The ear tip piece of claim 1 , further comprising an insertion device.

19. The ear tip piece of claim 1 , wherein the sound attenuator is replaceable.

20. The ear tip piece of claim 1 , wherein the sound attenuator is positioned inside the channel close to the first end.

21. The ear tip piece of claim 15 , wherein the interior curve has an angle of approximately 72°±/−15°.

22. An ear tip piece for insertion in an ear canal to attenuate sound being transmitted to the ear, comprising:

a first end including a solid portion that is sized and shaped to be inserted into and align the ear tip piece in the ear canal;

a second end including a reversibly compressible portion formed by a hollow having flexible walls that adapt to the shape of the ear canal to create a seal;

a bend between the first end and second end, the bend comprising an interior curve and an opposite curve that are sized and shaped to facilitate insertion of the ear tip piece at or near a first or second bend of the ear canal;

a channel formed in the solid portion that is open to the hollow for transmitting sound to the ear; and

a sound attenuator positioned in the channel to attenuate sound transmitted to the ear, wherein the sound attenuator is positioned proximal to the ear drum when the ear tip piece is inserted in the ear canal.
