ABSTRACT:
Pocket hearing aids are to be designed to be more comfortable. To this end there is provision on one hand for a wireless communication connection to be established between the microphone part and the earpiece part. To this end the microphone device of the pocket hearing aid has an appropriate electronics section (1) and an antenna (4), which can simultaneously be used as a clip. In order on the other hand to be able to dispense with feeding in external signals over a cable connection, the microphone device further features an adapter connector (5) with which for example it can be plugged in directly to a training device, a stereo device or a mobile telephone.
