Hearing device
View Patent ↗The space in hearing device housings ( 1, 2 ) is to be enabled to be used more intensively. To this end, the invention pro-poses dispensing with a separate microphone housing and embodying said housing in one piece with the hearing device housing. To reduce the microphone's sensitivity to body sound the corresponding attenuation can be provided in the hearing device shells or the non body-sound-sensitive Silicon microphones ( 5 ).
1. A hearing device, comprising:
a behind-the-ear hearing device housing comprising at least one shell member tapered toward an acoustic output and wearer hook; and
a microphone in the hearing device housing spaced apart by a defined distance from a tapered section of a curved interior surface of a first of the at least one shell member, thereby providing a back volume acoustically behind the microphone between the microphone and the tapered section.
2. The hearing device according to claim 1 , wherein the microphone is a Silicon microphone, and the back volume so provided is acoustically coupled to the Silicon microphone.
3. The hearing device according to claim 2 , further comprising a cover arranged upstream of the microphone in an audio signal direction aiming toward a microphone chip of the microphone, effective to provide acoustic separation of the microphone from other elements of the interior of the hearing device housing.
4. The hearing device according to claim 1 , wherein the microphone is positioned on a circuit board electrically connected to the hearing device housing by contact springs.
5. The hearing device according to claim 4 , wherein circuit paths formed by MID-technology are arranged on the hearing device housing for contacting the circuit board.
6. The hearing device according to claim 1 , wherein a plurality of microphones are arranged on a common circuit board in the hearing device housing.
7. The hearing device according to claim 1 , wherein the microphone is arranged on a hearing device circuit board accommodating signal processing components of the hearing device.
8. The hearing device according to claim 1 , wherein the hearing device housing comprises the first and a second shell member and the microphone is fixed to the first shell member and the electronic components of the hearing device are fixed to the second shell member.
9. The hearing device according to claim 1 , wherein the hearing device housing comprises an upper housing shell half and a lower housing shell half which are tapered towards an acoustic output and end in a wearer hook.
10. The hearing device according to claim 9 , wherein the microphone is located in a cavity of the upper housing shell half towards a tapered section.
11. A hearing device, comprising:
a behind-the-ear hearing device housing comprising at least one shell member tapered toward an acoustic output and wearer hook, and comprising a curved interior surface defining a cavity; and
a circuit board positioned in the cavity; and
a microphone on the circuit board thusly spaced apart by a defined distance from a tapered section of the curved interior surface, thereby defining an adjacent back volume in the cavity between the microphone and the tapered section,
wherein the back volume so provided is acoustically coupled to the microphone.
12. The hearing device according to claim 11 , wherein the microphone is a Silicon microphone.
13. The hearing device according to claim 12 , further comprising a cover arranged upstream of the microphone in an audio signal direction aiming toward a microphone chip of the microphone, effective to provide acoustic separation of the microphone from other elements of the interior of the hearing device housing.
14. The hearing device according to claim 11 , wherein the circuit board is electrically connected to the hearing device housing by contact springs.
15. The hearing device according to claim 14 , wherein circuit paths formed by MID-technology are arranged on the hearing device housing for contacting the circuit board.
16. The hearing device according to claim 11 , wherein a plurality of microphones are arranged on a common circuit board in the hearing device housing.
17. The hearing device according to claim 11 , wherein the circuit board is a hearing device circuit board accommodating signal processing components of the hearing device.
18. The hearing device according to claim 11 , wherein the hearing device housing comprises the first and a second shell member and the microphone is fixed to the first shell member and the electronic components of the hearing device are fixed to the second shell member.
19. The hearing device according to claim 11 , wherein the hearing device housing comprises an upper housing shell half and a lower housing shell half which are tapered towards an acoustic output and end in a wearer hook.
20. The hearing device according to claim 19 , wherein the microphone is located in a cavity of the upper housing shell half towards a tapered section.
