Angle piece at hearing devices
View Patent ↗At the exit of a hearing device ( 3 ) (for producing acoustic or sound-signals) a tube-like connecting-element or an angle piece ( 21 ) is arranged. At the end of the connecting element or angle piece ( 21 ) a thread ( 23 ) is arranged for connecting a tube ( 29 ) for sound or acoustic transmission of the signal of the hearing device into an ear-cannel.
1. Hearing-device for being worn at the pinna or behind the ear, respectively, comprising an exit for sound-signals, characterized in, that at the exit an angle piece is arranged for connecting the exit with a threadless tube for the sound transmission to an ear canal;
wherein the angle piece has a thread at one end for an attachment of the threadless tube to the angle piece;
wherein an outline of the thread has an edge and the thread is configured for engaging and retaining the threadless tube by either a force-fit slipping of the threadless tube over the edge of the thread or by a screwing the threadless tube over the thread.
2. Hearing device according claim 1 characterized in that between the thread and a wall of the angle piece respectively a sealing-surface is arranged.
3. Hearing-device according to claim 1 wherein the angle piece is configured for connecting with thicker acoustic transmission-tubes when the hearing device is a power-hearing device.
4. Hearing device according to claim 1 , wherein the thread is configured to facilitate removal of the threadless tube from the angle piece without damaging the hearing device by allowing the threadless tube to be screwed off from the angle piece.
5. Hearing device according to claim 1 , wherein the thread is sharp-edged.
6. Hearing device according to claim 1 , wherein the thread includes an inclined angle; wherein the inclined angle facilitates removal of the threadless tube from the angle piece without damaging the hearing device by allowing the threadless tube to be removed from the angle piece.
7. Process for the connection of an acoustic threadless transmission tube at an exit of a hearing device to an angle piece or ear-hook of the hearing device characterized in that the end of the acoustic threadless transmission tube is attached to the threadless tube by either a force-fit slipping of the threadless tube over an edge of a thread arranged at an end of the angle piece or the tube is screwed onto the thread.
8. Process according to claim 7 , farther comprising the step of removing the threadless tube from the angle piece, wherein the thread on the angle piece is configured to facilitate removal of the threadless tube without damaging the hearing device by allowing the threadless tube to be screwed off from the angle piece.
9. Process according to claim 7 , wherein the thread is sharp-edged.
10. Process according to claim 7 , farther comprising the step of removing the threadless tube from the angle piece, wherein the thread on the angle piece includes an inclined angle and the thread is configured to facilitate removal of the threadless tube without damaging the hearing device by allowing the threadless tube to be removed from the angle piece.
11. A hearing-device for being worn at the pinna or behind the ear comprising:
an exit for transmitting sound-signals wherein the exit is located at an end of the hearing-device;
a threadless tube-like connecting-element or an angle piece screwed onto a thread of the hearing device at the exit;
wherein the threadless tube-like connecting-element or the angle piece is arranged for connecting the exit with a tube for the sound transmission to an ear-canal; and
wherein the connecting-element or the angle piece has a thread at one end wherein the thread has an edge and the thread is configured for an attachment of the threadless tube over the edge of the thread to the connecting-element or the angle piece by either a force-fit slipping of the threadless tube over the edge of the thread or by a screwing the threadless tube over the thread.
12. Hearing-device according to claim 11 , wherein between the thread and a wall of the connecting element or the angle piece respectively a sealing-surface is arranged.
13. Hearing device according to claim 11 , wherein the thread is configured to facilitate removal of the threadless tube from the angle piece without damaging the hearing device by allowing the threadless tube to be screwed off from the angle piece.
14. Hearing device according to claim 11 , wherein the thread is sharp-edged.
15. Hearing device according to claim 11 , wherein the thread includes an inclined angle; wherein the inclined angle facilitates removal of the threadless tube from the angle piece without damaging the hearing device by allowing the threadless tube to be removed from the angle piece.
