ITE hearing aid for binaural hearing assistance
View Patent ↗Between ITE hearing aids for binaural hearing assistance, energy-saving communication is made possible by disposing an antenna device with a preferred direction of transmission in the hearing aid housing such that, in a state in which the hearing aid is attached to or inserted one ear of the patient, the preferred direction of transmission is substantially toward the other ear of the patient. In this way it is ensured that the directions of transmission of the two hearing aids in the fitted state lie substantially on a straight line, so that optimum transmission can be achieved.
1. An ITE hearing aid for binaural hearing assistance of a patient, comprising:
a housing configured to be received and held in one ear of a subject;
an antenna device having a single preferred transmission direction; and
a mounting for said antenna device in said housing that orients said antenna device in said housing to cause said single preferred transmission direction, when said housing is received and held in said one ear of the subject, to be oriented substantially toward the other ear of the subject.
2. An ITE hearing aid as claimed in claim 1 wherein said antenna device comprises an antenna coil.
3. An ITE hearing aid as claimed in claim 1 wherein said housing is a CIC hearing aid housing.
4. An ITE hearing aid as claimed in claim 1 wherein said mount comprises a mounting plate in said housing, said antenna device being disposed at an angle in a range between 10° and 40° relative to the normal of said mounting plate.
5. An ITE hearing aid as claimed in claim 1 wherein said mount comprises a mounting plate in said housing, said antenna device being disposed at an angle in a range between 20° and 30° relative to the normal of said mounting plate.
6. An ITE hearing aid as claimed in claim 1 wherein said mount comprises a battery spring configured to contact a battery spring having an extension arm to which said antenna device is fastened.
7. An ITE hearing aid as claimed in claim 1 comprising an electronics module also mounted on said mount.
8. An ITE hearing aid as claimed in claim 7 comprising programming contacts for said electronics module, said programming contacts also being disposed on said mount.
