The device includes electroacoustic transducers mounted at sound apertures in the housing, a keypad mounted between the apertures, and electronic circuitry. Video communication is accomplished by a video camera mounted in the housing and connected with the electronic circuitry and a liquid crystal display device mounted in the housing and connected to the electronic circuitry. Thus a radiotelephone is equipped with a video pickup device and a video display device.
