A DIGITAL HEARING AID WITH A VOLTAGE CONVERTER |
摘要 |
A digital hearing aid comprises a microphone (2), an output transducer (3), a digital signal processor (5) interconnected between the microphone and the output transducer, and a power source (7) including a standard hearing aid battery for the supply of operation voltage for the digital signal processor. At least one of the integrated circuit signal processing parts is designed to operate at a reduced unstabilized operation voltage substantially below a nominal voltage of the battery. A switched step-down voltage converter is connected between the power source and such signal processing parts for lowering the battery voltage to provide the reduced operation voltage. |
