Abstract
A radio communications system is disclosed as incorporating a high freque electrical signal generator employed for energizing a light emitting diode, the latter of which projects its light toward a vibratable, flexible, light-reflecting diaphragm for reflection thereof thereby. The light reflected from said diaphragm is received by a photodiode which, in turn, energizes a radio transmitter with electrical energy that is proportional thereto for the effective broadcast thereof toward a, perhaps, remotely disposed compatible radio receiver and/or other utilization apparatus. The aforesaid diaphragm vibrates in response to an acoustical communication signal applied thereto, thereby causing it to effectively vibrate and modulate the light reflected thereby therewith and, hence, the broadcast thereof toward said remotely disposed radio receiver is ultimately effected.
