Abstract

A hearing device includes: a sound tube; a receiver configured to provide sound via the sound tube; a housing configured to accommodate the receiver; a compartment in the housing; and a channel extending from the compartment and terminating at a location that is in fluid communication with a space in the sound tube.

First claim

1 . A hearing device comprising:
a sound tube; a receiver having a first side with a receiver opening, and a second side opposite from the first side, the receiver opening configured to provide output sound into the sound tube; a housing configured to accommodate the receiver; a compartment in the housing; and a channel extending from the compartment and terminating at a location that is in fluid communication with a space in the sound tube, wherein the location at which the channel terminates is away from the receiver opening, and is closer to the first side of the receiver with the receiver opening than to the second side of the receiver.

2 . The hearing device of claim 1 , wherein the compartment defines a receiver back-volume configured to increase a sound bandwidth for the hearing device.

3 . The hearing device of claim 1 , wherein the channel is configured to equalize pressure between the compartment and the space in the sound tube.

4 . The hearing device of claim 1 , wherein the receiver comprises a first chamber, a second chamber, and a membrane between the first chamber and the second chamber;
wherein the first chamber is associated with the sound tube; and wherein the second chamber is associated with the compartment.

5 . The hearing device of claim 1 , wherein the channel is configured to equalize pressure between a first space outside the first chamber and a second space outside the second chamber.

6 . The hearing device of claim 1 , further comprising a receiver suspension, wherein at least a part of the channel is defined or covered by a portion of the receiver suspension.

7 . The hearing device of claim 1 , wherein at least a part of the channel is between a wall of the compartment and a surface of the receiver.

8 . The hearing device of claim 1 , wherein at least a part of the channel is defined by a wall of the compartment and/or a surface of the receiver.

9 . The hearing device of claim 1 , wherein the compartment is sealed from a surrounding of a user of the hearing device when the hearing device is worn by the user.

10 . The hearing device of claim 1 , wherein the channel is configured to relieve pressure in the compartment to the sound tube and/or vice versa.

11 . The hearing device of claim 1 , further comprising a microphone configured to provide a microphone signal, wherein the microphone is coupled to the receiver.

12 . The hearing device of claim 1 , further comprising an antenna configured to receive wireless signal, wherein the receiver is configured to provide the sound based on the wireless signal.

13 . The hearing device of claim 1 , wherein at least a part of the channel is in the sound tube.

14 . The hearing device of claim 1 , wherein the sound tube comprises an interior wall, and an opening at the interior wall; and
wherein the opening at the interior wall of the sound tube is in fluid communication with the channel.

15 . The hearing device of claim 1 , further comprising a seal surrounding the sound tube.

16 . The hearing device of claim 1 , wherein the hearing device is a hearing aid.

17 . The hearing device of claim 1 , wherein the hearing device is a hearing protection device.

18 . The hearing device of claim 1 , further comprising a processing unit configured to perform signal processing based on a hearing loss characteristic of a user of the hearing device.
