Wireless phone powered inductive loopset
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.
1. 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.
2. The loopset of claim 1 , further comprising a microphone, wherein the microphone is selectively supplied power responsive to the activation state of the wireless device.
3. The loopset of. claim 2 , wherein the microphone is selectively supplied power independently from the power being supplied to the loopset.
4. The loopset of claim 1 , wherein the switch is embedded in the wireless device.
5. The loopset of claim 1 , wherein the switch is placed in an auxiliary device between the wireless device and the loopset.
6. 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.
7. The method of claim 6 , wherein the step of selectively supplying power comprises the step of detecting a change in the activation state of the wireless device and controlling a switch based on the detecting step.
8. The method of claim 7 , wherein the switch is located within the wireless device.
9. The method of claim 7 , wherein the switch is located outside of the wireless device.
10. The method of claim 6 , wherein the switch is embedded in the wireless device.
11. The method of claim 6 , wherein the switch is placed in an auxiliary device between the wireless device and the loopset.
