Voice-activated ship’s telephone

This ‘loud-speaking’ hands-free voice-activated phone is made mainly of brass, and some parts are painted white. The speaker’s voice caused a metal diaphragm to vibrate, which moved a wire coil within a magnetic field. This generated sufficient current to power the phone.
