- the hearing aid 220 has a hearing aid housing 240 comprising a microphone 260, a signal processor 250, a wireless communications unit 230.
- An attachment member 200 comprises electrical conductor 280 transmitting the second audio signal from the signal processor 250 to the receiver in the ear 270.
- the receiver in the ear 270 is provided in an ear mould 290 configured to be positioned in the ear of a user.
- the wireless communications unit 230 is interconnected with an antenna having a first pole element 211 extending along the attachment member 200.
- the first pole element extends within the attachment member and an insulating material may be provided between the first pole element 211 and the electrical conductor 280, e.g. to avoid cross talk.
- a second pole element 212 extends within the hearing aid housing 240.
- Fig. 9 shows the intended operational position of the hearing aid 320 behind the ear 900 of a user.
- the attachment member 300 is conveniently located at a face 344 of the hearing aid housing 320.
- the top side of the hearing aid is the side of the hearing aid housing 320 furthers away from the ear
- the side 341 is the side of the hearing aid adjacent the head (not shown) of a user
- the side 342 is the side of the hearing aid exposed to the surroundings, i.e. exposed to the surroundings through the thin outer ear which is substantially loss less for the electromagnetic or RF radiation.
- Figs. 10a-d show fixed lengths of antennas 311 extending in attachment members 301, 302, 303, 304 of different lengths.
- the fixed lengths antennas may be monopole antennas, or the fixed length antennas may be dipole antennas wherein only one pole element of the dipole antenna is shown.
- Figs. 11a-d show variable lengths of antennas 321, 322, 323, 324 extending in attachment members 301, 302, 303, 304 of different lengths.
- Table 1 shows exemplary lengths of the attachment members for an attachment member being a sound tube.
