First Claim
Patent Images
1. A VOLUME CHANGER ARRANGEMENT COMPRISING ALTERNATING SIGNAL INPUT MEANS, A PAIR OF RESISTORS CONNECTED IN SERIES BETWEEN SAID SIGNAL INPUT MEANS AND GROUND, AT LEAST ONE OF SAID RESISTORS BEING A MAGNETO-RESISTANCE DEVICE HAVING A RESISTANCE VALUE THAT VARIES IN RESPONSE TO MAGNETIC FIELDS, MEANS FOR ESTABLISHING A MAGNETIC FIELD ADJACENT SAID MAGNETO-RESISTANCE DEVICE, AND MEANS FOR CONTROLLING THE INTENSITY OF THE MAGNETIC FIELD ESTABLISHED BY SAID FIELD-ESTABLISHING MENS WITH A VOLTAGE DERIVED FROM THE INUT SIGNAL PASSING THROUGH THE VOLUME CHANGER ARRANGEMENT.
