Abstract

A suspension for a hearing device receiver includes: a receiver holding part; and a damping structure with a body and a receiver base, the body comprising a first body part, the damping structure having an inner surface forming a sound duct, the sound duct extending through the first body part, the damping structure having a first opening at a first sound duct end, the first opening configured for connecting an output port of a receiver, the damping structure having a second opening at a second sound duct end, the sound duct providing a sound path for conveying sound energy from the receiver through the damping structure to the second opening, the first body part extending from the receiver base; wherein the damping structure comprises a first damping element connecting the body and the receiver base so that the receiver base is separate from and in parallel to the first body part.

First claim

The invention claimed is:

1. A suspension for a receiver in a hearing device, comprising:
a receiver holding part; and
a damping structure with a body and a receiver base, the body comprising a first body part, the damping structure having an inner surface forming a sound duct in the damping structure, the sound duct extending through the first body part, the damping structure having a first opening at a first sound duct end, the first opening configured for connecting an output port of a receiver to the sound duct, the damping structure having a second opening at a second sound duct end, the sound duct providing a sound path for conveying sound energy from the receiver through the damping structure to the second opening, the first body part having a longitudinal axis and extending from the receiver base;
wherein the damping structure comprises at least a first damping element connecting the body and the receiver base, the first damping element having an intermediary segment that is separate from the longitudinal axis of the first body part.

2. The suspension according to claim 1 , wherein the body comprises a second body part positioned between the second sound duct end and the first body part, the sound duct extending through the second body part, the second body part having a corrugated outer surface.

3. The suspension according to claim 1 , wherein the first damping element extends from the receiver base to the body forming a gap between the first damping element and the first body part.

4. The suspension according to claim 1 , wherein the first body part comprises a second damping element extending from the receiver base.

5. The suspension according to claim 2 , wherein a first longitudinal axis of a first sound duct part in the first body part, and a second longitudinal axis of a second sound duct part in the second body part form an angle that is anywhere from 15° to 45°.

6. The suspension according to claim 5 , wherein the first damping element, in a first cross section that is perpendicular to the first longitudinal axis, covers an area of less than 10% of a receiver base area.

7. The suspension according to claim 2 , wherein the body comprises a third body part between the first body part and the second body part for absorbing a part of vibrational energy from the receiver.

8. The suspension according to claim 1 , wherein a first outer surface of the first body part in a cross section perpendicular to the sound duct is non-circular.

9. The suspension according to claim 1 , wherein the receiver holding part forms a receiver compartment and comprises a first portion connected to the receiver base, and a second portion, wherein the first portion and the second portion are connected by a plurality of bridging elements.

10. The suspension according to claim 9 , wherein the second portion comprises an insertion opening for insertion of a hearing aid receiver in the receiver compartment.

11. The suspension according to claim 9 , wherein the second portion of the receiver holding part comprises a plurality of cushioning zones for absorbtion of mechanical shock.

12. The suspension according to claim 1 , wherein the damping structure comprises a mounting element at the second opening for mounting the suspension to a structural frame of the hearing device.

13. A hearing device comprising:
a receiver;
a hearing device structural frame; and
a suspension, wherein the receiver is mounted in the suspension;
wherein the suspension comprises:
a receiver holding part; and
a damping structure with a body and a receiver base, the body comprising a first body part, the damping structure having an inner surface forming a sound duct in the damping structure, the sound duct extending through the first body part, the damping structure having a first opening at a first sound duct end, the first opening configured for connecting an output port of the receiver to the sound duct, the damping structure having a second opening at a second sound duct end, the sound duct providing a sound path for conveying sound energy from the receiver through the damping structure to the second opening, the first body part having a longitudinal axis and extending from the receiver base;
wherein the damping structure comprises at least a first damping element connecting the body and the receiver base, the first damping element having an intermediary segment that is separate from the longitudinal axis of the first body part.

14. The hearing device according to claim 13 , wherein the output port of the receiver is positioned in the first opening of the sound duct.

15. The suspension according to claim 1 , wherein the intermediary segment of the first damping element and the first body part form a side-by-side configuration and are both connected to the receiver base.

16. The hearing device according to claim 13 , wherein the intermediary segment of the first damping element and the first body part form a side-by-side configuration and are both connected to the receiver base.
