Claims
- 1. A hearing aid apparatus being operable with the help of an electrical supply source comprising a voltage stabiliser generating from the voltage of said supply source a stabilised supply voltage, said voltage stabiliser comprising an upwards and/or downwards controller generating said stabilised supply voltage from higher and/or from lower voltages of said supply source.
- 2. The apparatus of claim 1, wherein said controller is realised as a switched controller.
- 3. The apparatus of claim 1, wherein said stabilised supply voltage generated by said stabiliser is adjustable.
- 4. The apparatus of claim 1, wherein there is provided an inductive element operationally interconnected between said source and an output of said stabiliser for said stabilised supply voltage.
- 5. The arrangement of claim 4, wherein said inductance includes an inductance of an output electrical to mechanical converter of said hearing aid.
- 6. The apparatus of claim 1, wherein said stabiliser generates more than one stabilised output voltage.
- 7. The apparatus of claim 2, wherein said stabilised supply voltage generated by said stabiliser is adjustable.
