Abstract
In an audio message communication apparatus for an automobile, a portable radiotelephone is supported on a holder which is mounted forwardly of a driving compartment. An external amplifier and an external microphone are connected through the holder to an earphone microphone terminal of the radiotelephone. The external amplifier is connected to an external speaker for amplifying a received audio signal of the radiotelephone which is converted into a voice so as to be generated in a form of a loud voice. A transmitting voice is entered through the external microphone into the radiotelephone. With the above construction, the audio message communication is effectively achieved with an operator's hands free.
