Abstract
A push-to-talk device (PTT) and corresponding methods of operation are disclosed. The PTT device is configured to interoperate with microphone-equipped headsets having different wiring conventions and microphone systems. The PTT device includes a housing, a jack configured to receive a plug of the headset, a plug configured to connect the PTT device to a communication radio, and signal processing circuitry disposed within the housing. The signal processing circuitry is configured to detect a wiring convention of the headset and to route audio signals between the headset and the communication radio in accordance with the detected wiring convention. The signal processing circuitry is also configured to detect a type of microphone system of the headset.
Claims20
A push-to-talk device configured to connect a communication radio with a headset, the push-to-talk device comprising:
- a housing;
- a jack configured to receive a plug of the headset;
- a plug configured to connect the push-to-talk device to the communication radio;
- and
- signal processing circuitry disposed within the housing and configured to:
- detect a wiring convention of the headset;
- and
- detect a type of microphone system of the headset.
A method of operating a push-to-talk device configured to interconnect a headset and a communication radio, the method comprising:
- receiving a plug of the headset in a jack of the push-to-talk device;
- assessing, using a comparator of the push-to-talk device, a test line of the headset to determine whether the test line is connected to ground;
- and
- routing audio lines between the headset and the communication radio based on whether the test line is connected to ground.
A push-to-talk device configured to connect a communication radio with a headset, the push-to-talk device comprising:
- a housing;
- a jack configured to receive a plug of the headset;
- a plug configured to connect the push-to-talk device to the communication radio;
- an onboard power source;
- and
- an integrated charging circuit electrically coupled to the onboard power source and configured to draw phantom power through a positive lead of a microphone system of the headset to recharge the onboard power source.
