Portable audio device

摘要

Personal audio relay apparatus includes a mobile telephone and a portable audio signal source device such as an MP3 player. Once a telephone call has been established a user can operate the control means causing the telephone to receive at telephone input audio programme material over line from the audio source. This allows the remote party at the other end of the telephone call to hear the audio programme. As well as allowing music to be shared the arrangement serves to provide music to the remote party when they are placed on 'hold' thereby allowing a party to know that the call has not been terminated. During this time, audio input from the normal telephone microphone may be muted.
