Voice Powered Headsets

Voice Powered Communications
Most Communications systems require an AC or DC power source. David Clark Company's Voice Powered System only requires Your Voice to generate the power needed. David Clark Company's Voice Powered Communication System is a more sophisticated mechanical version of two tin cans connected by a string. When you speak, your voice travels to a transmitter causing fluctuations in a magnetic circuit. This creates a small amount of current(approximately 20 micro amperes), which is enough to operate the receivers on up to six headsets. In its simplest application, a Voice Powered System can be just two Headsets and a jumper cord.
