20140198924 | HEADSET WITH AUXILIARY INPUT(S) FOR CELL PHONE AND/OR OTHER DEVICES - An active-noise-reduction (ANR) headset includes at least one auxiliary connection to an output of at least one device, such as a personal communications, computing, and/or entertainment device. An exemplary headset also includes a primary connection to a two-way radio or public-address system and circuitry for automatically suppressing or muting the volume of an auxiliary input signal relative to that of a primary input signal. Other exemplary features include a headset power supply, a microphone, a microphone preamplifier, and a device-detection circuit. The device-detection circuit selectively couples the power supply to the microphone preamplifier, enabling it to provide audio signals to the microphone input of the auxiliary device. | 07-17-2014 |
