Hearing device with RF communication

1. A hearing device with an acoustical-to-electrical converter arrangement, an electrical-to-mechanical converter arrangement, at least one audio signal processing unit with an input operationally connected to an output of said acoustical-to-electrical converter arrangement and with an output operationally connected to an input of said electrical-to-mechanical converter arrangement and further with an Rf antenna and an Rf signal processing unit operationally connected to said Rf antenna and to said audio signal processing unit, wherein said Rf antenna is incorporated in a first module and said audio signal processing unit is incorporated in a second module, said first and second modules being completely incorporated within an outer shell of the hearing device, said first and second modules being mechanically and electrically interconnected by a releasable positive locking link, wherein said first module with the Rf antenna is interchangeable with a different first module with a different Rf antenna having a different spatial orientation, and Rf communications of the hearing device are changed when the first module is replaced with the different first module.

2. The hearing device of claim 1 , wherein said first module further comprises said Rf signal processing unit.

3. The hearing device of claim 1 , wherein said second module further comprises said Rf signal processing unit.

4. The hearing device of claim 1 , wherein said Rf antenna and said Rf signal processing unit constitute an Rf receiver arrangement or an Rf transmitter arrangement or an Rf receiver and transmitter arrangement.

5. The hearing device of claim 1 , wherein said first module further comprises said Rf signal processing unit and wherein said first module comprises a first submodule comprising said Rf antenna and a second submodule comprising said Rf signal processing unit, said first and second submodules being mechanically interconnected by a releasable positive locking link.

6. The hearing device of claim 1 being one of an in-the-ear hearing device and of an outside-the-ear hearing device.

7. The hearing device of claim 1 being one hearing device of a binaural system.

8. The hearing device of claim 1 , wherein said releasable positive locking link is one of a bayonet link, a screwing link, a snap link, and a groove and tongue link.

9. The hearing device of claim 1 , further comprising a code unit in or at the first module and a code reader and decoding unit at or in the second module.

10. The hearing device of claim 1 , wherein said second module comprises submodules which are interconnected by means of releasable positive locking links.

11. The hearing device of claim 1 , wherein said second module further comprises said acoustical-to-electrical converter arrangement.

12. The hearing device of claim 1 , further comprising an audio coil within said first module.

13. A hearing device with an acoustical-to-electrical converter arrangement, an electrical-to-mechanical converter arrangement, at least one audio signal processing unit with an input operationally connected to an output of said acoustical-to-electrical converter arrangement and with an output operationally connected to an input of said electrical-to-mechanical converter arrangement and further with an Rf antenna and an Rf signal processing unit operationally connected to said Rf antenna and to said audio signal processing unit, wherein said Rf antenna is incorporated in a first module and said audio signal processing unit is incorporated in a second module, said first and second modules being completely incorporated within an outer shell of the hearing device, said first module being introducible into a recess of said outer shell such that a surface of the first module is flush with a surface of said outer shell, and said first and second modules being mechanically and electrically interconnected by a releasable positive locking link, wherein said first module with the Rf antenna is interchangeable with a different first module with a different Rf antenna having a different spatial orientation, and Rf communications of the hearing device are changed when the first module is replaced with the different first module.

14. The hearing device of claim 13 , wherein said first module has a casing.

15. A method for optimizing mutual Rf-communication between a first hearing device and a second hearing device of a binaural hearing system, comprising the steps of:

replacing, at the first hearing device, a module comprising an antenna having a spatial orientation with another module comprising another antenna having a different spatial orientation; and

repeating the step of replacing using further modules comprising further antennas having further different spatial orientation until an optimum Rf communication is found.

16. The method of claim 15 , wherein the step of replacing includes mechanically and electrically interconnecting said another module to a second module comprising an audio signal processing unit, using a releasable positive locking link,

wherein said second module is incorporated within an outer shell of the first hearing device, and said another module is introducible into a recess of the outer shell or is incorporated within the outer shell.
