ABSTRACT:
A combined microphone and accessory device is disclosed for operation with a transmitter radio having a microphone audio circuit and a transmitter activating circuit. The transmitter activating circuit has a first and a second terminal with a potential established therebetween for activating the transmitter radio upon conduction of a given current level between the first and second terminals. The invention comprises a microphone housing having a microphone adapted for connection to the microphone audio circuit of the transmitter radio. A microphone key switch is mounted to the microphone housing and adapted for connection to the transmitter activating circuit for conducting the given current level between the first and second terminals upon closing the microphone key switch to activate the transmitter radio. An accessory device such as an illumination device, a timer or a calculator, is mounted in the microphone housing and is powered by a rechargeable battery within the microphone housing. An accessory switch connects the rechargeable battery to power the accessory device upon closing the accessory switch. A recharging circuit connects the first and second terminals to the rechargeable battery for charging the rechargeble battery at a current level less than the given current level required to activate the transmitter radio. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
