The circuit transducer and process to convert an acoustic signal into an electrical signal, and,Set of microphone for transmitting part of a device radiotelefu00c8nico operable in a communication system radiotelefu00c8nica.The circuit transducer and an associated process, converts acoustic signals into electrical signals.The circuit includes a transducer diaphragm which is positioned to receive acoustic signals, such as voice signals.Displacement of the diaphragm responsive to reception of the acoustic signals is detected using light energy in the direction of the diaphragm and detecting characteristics of the light energy reflected outThe diaphragm. Changes in the characteristics of the light energy are determinativas of displacement of the diaphragm and, in turn, values of the acoustic signals received by the diaphragm.When implemented in a radiotelephone device.The diaphragm may be positioned in a better location for detecting voice signals generated by a user without the need to position electrical conductors to extend to the diaphragm.Or a winding positioned about him, to detect displacement of the diaphragm.
