Abstract
A sound emission and collection device has a plurality of speakers () and a plurality of microphones. The speakers each have a sound emission surface arranged on the side surface of a case () so that sound can be emitted in all circumferential directions. The microphones () each are arranged with the sound collection direction set in the center direction of the case (). The microphone () and the speaker () have directivities opposing to each other to minimize a wraparound sound from the speaker () to the microphone (). Moreover, since the speaker () and the microphone () are arranged on circumferences of concentric circles, it is possible to obtain a compact configuration.
