Abstract
In a video teleconference device, a microphone and a speaker are arranged in a housing in such a manner that a voice input direction of the microphone and a voice output direction of the speaker are roughly orthogonal to each other. With that, the sound coming out of the speaker is not easily received as input by the microphone. Thus, with such a simple configuration, it becomes possible to effectively curb the echo effect and the howling effect.
