Abstract

A hearing aid device comprising a receiver unit arranged in a compartment in a shell, wherein the shell comprises a venting passage between first and second opposite faces of the shell to provide air passage from one side of the shell to another, and wherein the shell comprises an opening in the first face into the compartment and a closing member positioned to close off the compartment. The opening is shaped to allow the receiver unit to be inserted into the compartment through the opening, and the compartment is acoustically connected to the venting passage to allow the sound to emit through the venting passage. The receiver unit may be releasably mounted in the compartment such that the receiver unit can be retracted from the shell through the opening.

First claim

The invention claimed is:

1. A device for emitting sound to an ear of a user, comprising:
a shell adapted to fit within an ear canal of the user and including a compartment therein, the shell having a first face for facing toward an interior of the ear and a second face for facing toward the surroundings of the user, the shell providing a venting passage between the first and second faces for permitting air to pass between the first and second faces, the first face including an opening that leads to the compartment;
a closing member positioned at the opening for closing off the compartment; and
a receiver unit mounted within the compartment by suspension elements, the opening of the first face being shaped to allow the receiver unit to be inserted into the compartment though the opening, the compartment being acoustically connected to the venting passage such that sound emitted by the receiver unit is guided from the compartment and out of the shell via the venting passage.

2. A device according to claim 1 , wherein the suspension elements include elastomeric structures that partly encircle the receiver unit.

3. A device according to claim 1 , wherein the suspension elements include elastomeric structures that fully encircle the receiver unit.

4. A device according to claim 3 , wherein the elastomeric structures include one of the group consisting of boots, strips, and ribbons.

5. A device according to claim 1 , wherein the suspension elements include shock absorbing protrusions positioned between the receiver unit and walls of the compartment.

6. A device according to claim 1 , wherein the suspension elements attenuate mechanical vibrations of the receiver unit.

7. A device according to claim 1 , wherein the closing member comprises a lid or plug releasably attached to the shell.

8. A device according to claim 1 , wherein the receiver unit is attached to the closing member.

9. A device according to claim 1 , wherein the receiver unit is releasably mounted in the compartment and is retractable from the opening on the first face of the shell.

10. A device according to claim 1 , wherein the device is a hearing aid device.

11. A device according to claim 1 , wherein the receiver unit comprises a sound outlet oriented in a direction away from the first face.

12. A device according to claim 1 , wherein the receiver unit comprises either one of a dual receiver, or a combination of a woofer and a tweeter.

13. A device according to claim 1 , wherein the compartment is acoustically connected to the venting passage via an acoustical channel segment.

14. A device according to claim 13 , further comprising a damper placed in the venting passage between the second face and the acoustical channel segment that connects to the compartment.

15. A device according to claim 13 , further comprising a wax protection mechanism placed in the venting passage between the first face and the acoustical channel segment that connects to the compartment.

16. A device for emitting sound to an ear of a user, comprising:
a shell adapted to fit within an ear canal of the user and including a compartment therein, the shell having a first face for facing toward an interior of the ear and a second face for facing toward the surroundings of the user, the first face including an opening that leads to the compartment, the shell including a venting passage extending between the first face and the second face, the compartment being acoustically connected to the venting passage such that sound emitted by the receiver unit is guided from the compartment and out from the first face via the venting passage;
a closing member that closes the opening on the first face; and
a receiver unit that is releasably mounted within the compartment such that the receiver unit can be retracted from the shell, the opening on the first face being shaped to allow the receiver unit to be inserted into the compartment.

17. A device according to claim 16 , wherein the closing member comprises a lid or a plug that is releasably attached to the shell.

18. A device according to claim 16 , wherein the receiver unit is retractable from the opening on the first face of the shell.

19. A device according to claim 16 , wherein the receiver unit comprises a sound outlet oriented in a direction away from the first face.

20. A device according to claim 16 , wherein the device is a hearing aid device.

21. A device according to claim 16 , wherein the receiver unit is releasable mounted within the compartment through suspension elements.

22. A device for emitting sound to an ear of a user, comprising:
a shell adapted to fit within an ear canal of the user and including a compartment therein, the shell having a first face for facing toward an interior of the ear and a second face for facing toward the surroundings of the user, the shell providing a venting passage between the first and second sides that provides air passage between the first and second sides, the shell including an opening that leads to the compartment;
a closing member positioned at the opening for closing off the compartment; and
a receiver unit located within the compartment, the opening being shaped to allow the receiver unit to be inserted into the compartment though the opening, the receiver unit including a sound outlet oriented in a direction away from the first face, and the compartment being acoustically connected to the venting passage such that sound emitted by the receiver unit is guided from the compartment and out of the shell via the venting passage.
