SWITCHING STRUCTURES FOR HEARING AID
First Claim
Patent Images
1. A hearing aid, comprising:
- an input system;
an output system;
a signal processing circuit electrically connecting the input system to the output system;
a magnetically actuatable switch between the input system and the signal processing circuit, the magnetically actuatable switch including a first position and a second position; and
a filter connected to the magnetically-actuatable switch, the first position of the switch electrically removing the filter from between the input system and the signal processing circuit, and the second position of switch electrically connecting the filter between the input system and the signal processing circuit.
