Abstract
An induction-type loopset is provided that is connectable to a wireless device. The loopset contains a first coil electromagnetically coupled to a t-coil hearing aid and an impedance-matching device coupled to the first coil. The impedance-matching device is responsive to an audio signal from the wireless device. The induction-type loopset is powered from the power source of the wireless device. The power source is responsive to an activation state of the wireless device.
Claims11
An induction-type loopset for the hearing impaired configured to be connected to a wireless device comprising:
- a first coil configured to be electromagnetically coupled to a t-coil hearing aid;
- and an impedance-matching device coupled to the first coil, the impedance-matching device being responsive to an audio signal from a wireless device, and wherein the induction-type loopset is selectively powered from the power source of the wireless device via a switch responsive to an activation state of the wireless device.
A method for selectively supplying power to an induction-type loopset for the hearing impaired, comprising the steps of:
- connecting a wireless device to the loopset;
- and selectively supplying power to the loopset from the wireless device via a switch responsive to an activation state of the wireless device.
