Speaker assembly for hearing aid
There is provided a hearing aid with a Receiver In The Ear speaker assembly comprising a connecting member with electric conductors connecting a connector at one end, and a receiver housing with a receiver at the opposite end. A microphone housing with a microphone is attached to the connecting member. The microphone housing with the microphone is separated by a distance from the receiver in the receiver housing, thus reducing acoustic or mechanical feedback problems. Especially, the microphone and connector may share one common housing.
1. A speaker assembly configured to releasably connect to a housing of a behind-the-ear (BTE) hearing aid, the speaker assembly comprising:
a receiver for generating an audible acoustic output into the user's ear canal in response to an electric signal, wherein the receiver is arranged in a first housing which is configured to be positioned in the user's ear canal during normal use of the speaker assembly,
a microphone for capturing sound and generating an electric output accordingly, the microphone having a microphone housing disposed apart from the first housing,
a connector housed in the microphone housing, the connector being configured to establish an electrical connection between the receiver and the housing of the BTE hearing aid, and
a connecting member comprising a flexible tube in which is disposed a plurality of separate electrical conductors for electrical connection to the connector at one end and for electrical connection to the receiver at the opposite end,
wherein the microphone is located outside the flexible tube at the one end of the electrical conductors for electrical connection to the connector.
2. The speaker assembly according to claim 1 , wherein the microphone is provided with a suspension member.
3. The speaker assembly according to claim 1 , wherein a first part of the connecting member has an enlarged cross-section proximate to the microphone housing.
4. The speaker assembly according to claim 3 , wherein the connecting wherein the connecting member is integrally formed of the first part and a second part, the second part including the flexible tube, the first part having a higher rigidity than the second part.
5. The speaker assembly according to claim 1 , further comprising at least part of an antenna.
6. The speaker assembly according to claim 5 , wherein the at least part of the antenna is formed in the connecting member.
7. The hearing aid according to claim 1 wherein:
the housing of the hearing aid is configured to hold at least an electric energy source configured for electric connection to the speaker assembly via the connector.
8. The hearing aid according to claim 7 , comprising an electronic circuit arranged in the housing of the hearing aid, wherein the electronic circuit comprises an amplifier circuit with an adjustable gain, so as to allow matching of a gain of the amplifier circuit with a configuration of the speaker assembly.
9. The hearing aid according to claim 8 , wherein the electronic circuit is configured to discriminate between a plurality of possible speaker assembly types and to set the adjustable gain of the amplifier circuit accordingly.
10. The hearing aid according to claim 1 , wherein a second microphone with a second microphone housing may be arranged within the connecting member.
11. The hearing aid according to claim 10 , wherein an antenna may be arranged at least partly in the connecting member, and a choke component is included in the second microphone housing to allow the antenna to have two different lengths, each of the different lengths supporting a different operational frequency.
