ABSTRACT:
A radiotelephone includes a speaker and at least one microphone, and is incorporated with the sun visor assembly of a vehicle. The speaker is included in the visor so as to radiate from the narrow side thereof which faces an occupant of the vehicle. The microphones are supported on an axially rotatable support rod which adjoins the opposite side of the sun visor and to which the sun visor is coupled so as to permit tilting thereof causing axial rotation of the support rod. The coupling is such that upward/downward tilting of the sun visor causes an opposite tilting of the main reception path between the microphones and the occupant of the vehicle, so that acoustic screening of the microphones by the sun visor cannot occur regardless of how the sun visor may be tilted.
