Abstract
A wireless telephone apparatus is disclosed which includes an acoustic transmission apparatus employing a telephone handset for use during a normal telephone conversation mode and a telephone headset for use during a hands-free telephone conversation mode. No speaker and microphone are used during the hands-free telephone conversation mode. The acoustic transmission apparatus includes a control section which normally connects the telephone handset to the wireless telephone apparatus, but is responsive to the operation of a selector or headset switch to connect the telephone headset without interrupting the telephone conversation. Similarly, the control section enables the user to switch back to using the telephone handset without interrupting the telephone conversation. A visual display is provided to indicate whether the telephone handset or the telephone headset is connected to the wireless telephone apparatus.
