Hearing device having two modules for assembling/disassembling device

1. A set of hearing devices, each with at least one acoustical to electrical converter, at least one electrical to mechanical converter, at least one signal processing unit and an electrical power supply unit wherein said electrical power supply unit and said electrical to mechanical converter of each of said hearing devices are incorporated in a first module, said acoustical to electrical converter as well as said signal processing unit are incorporated in a second module, said respective first and second module being assembled in a disassemblable manner at each of said hearing devices, said hearing devices having different acoustical to mechanical transmission powers, said second modules of said hearing devices being the same modules, and said first modules of said hearing devices being different modules.

2. The set according to claim 1 , wherein at least one first module of a hearing device of said set has an electrical power supply unit and an electrical to mechanical converter, which are unremovably integrated in said first module, said respective first module being integrally an exchange part.

3. The set according to claim 1 or 2 , wherein a first module of at least one of said hearing devices forming said set has an On/Off control arrangement for said respective hearing device.

4. The set according to claim 1 , wherein at least one second module of said hearing devices belonging to said set has a control arrangement for externally controlling said signal processing unit.

5. The set according to claim 1 , wherein said hearing devices forming said set being hearing aid devices and thereby one of In-The-Ear hearing aid devices and Outside-The-Ear hearing aid devices.

6. The set according to claim 1 , wherein at least one of said first modules of said hearing devices comprises a power supply unit, which is a rechargeable accumulator.

7. The set according to claim 1 , wherein at least one of said first modules comprises a power supply, which is at least one battery.

8. The set according to claim 1 , wherein at least one of said first modules has a power supply unit, which is exchangeable from said first module.

9. The set according to one of the claim 1 , said first modules having a code unit with a code, said codes of said first modules being different, said second modules having a code reader and decoder unit for reading and decoding said code of said first modules, the output of said code reader and decoding unit being operationally connected to at least one adjusting input of an electronic unit within said second module.

10. The set according to one of the claim 1 , further comprising an electronic unit respectively within said first modules and wherein said electronic units of said first modules are different.
