| Abstract: |
A device for enabling an earphone-microphone combination including a radio module to be used for a mobile phone, comprises a switching device for changing the operational mode of the radio module between telephoning mode and radio mode according to first and second mode selection signals, the radio module being muted in the telephoning mode, and a radio module interface connector connected with the hands-free kit interface connector of the mobile phone both to supply the power of the mobile phone battery to the radio module and to communicate the first and second mode signals and audio signals between the mobile phone and radio module or the earphone-microphone combination.

What is claimed is:
1. A device for enabling an earphone-microphone combination to be commonly used to provide radio listening and mobile phone operation, comprising:
- a switching device for changing an operational mode of a radio module between telephone mode and radio mode according to first and second mode selection signals, respectively, said radio module being muted by a muting circuit connected between said radio module and said earphone-microphone combination during said telephone mode; and
- a radio module interface connector connected with a hands-free kit interface connector of said mobile phone to communicate said first and second mode signals and mobile phone audio signals between said mobile phone and said radio module, said mobile phone audio signals being supplied to said earphone-microphone combination,
- wherein if a ring signal is detected upon detection of a first mode signal said muting circuit mutes said radio module and switches said mobile phone from an idle mode to a phone answer mode, else said muting circuit mutes said radio module and said mobile phone changes to a last number redial mode to allow a user to dial a telephone number or use a last number redial function.
