Hearing device with a special energy reception system and corresponding method

摘要

The ear piece unit has a signal processing device, an energy storage device (17), which is loaded with electricity and a transducer device (10) for converting an acoustic signal into an electrical signal or electrical signal into acoustic signal. A charging circuit is provided, which is connected between the transducer device and the energy storage device, so that energy is transferred acoustically or electromagnetically to the transducer device. The energy is fed electrically over the charging circuit into the energy storage device. Independent claims are also included for the following: (1) a battery charger with a sound generator to produce an acoustic energy transmitted signal (2) a method for charging energy storage device of an ear piece unit.
