Simultaneous multidirectional communication apparatus
First Claim
1. A simultaneous multidirectional communication apparatus comprising a repeater, and a plurality of transmitter-receivers simultaneously communicatable using radio waves with one another multidirectionally by way of said repeater,wherein a sound-shielded headset is adapted for said transmitter-receivers, and communication means is held at or near a human body, said communication means including a sound input/output section with a microphone and a speaker, and a transmitter/receiver function section for execution of signal processing tasks required for communications,characterized by comprising informing means for providing a warning signal and/or information to a user of a transmitter-receiver operatively coupled to said repeater, andsaid repeater transmitting information representative of an external signal input toward all of said transmitter-receivers by way of said informing means.

Abstract
A communication apparatus includes a plurality of transmitter-receivers operatively coupled together so that they are simultaneously communicatable over-the-air with one another by way of an interexchange repeater module, wherein one of such transmitter-receivers comes with a display device for providing information to the user, and a telephone connector for connecting the transmitter-receiver to the public telephone communication network. A sound-shielded headset is employed in the transmitter-receiver. This headset includes an audio input/output section with a microphone, speakers and the like, and a transmitter/receiver function section for executing signal processing tasks required for communications. Upon reception of a telephone signal, the transmitter-receiver is connected to the telephone connector by means of a cable-wiring, optical coupling or radio-wave coupling scheme providing voice communications with the outside parties. In case where the telephone connector is equipped with a known telephone set, voice communications will be available by entry of phone numbers over either external public lines or extension lines.
