SOUND EMISSION AND COLLECTION DEVICE
摘要:
It is possible to provide a sound emission and collection device having a compact configuration and being capable of suppressing a wraparound sound from a speaker to a microphone and improving the S/N ratio. In the sound emission and collection device, a plurality of speakers (11) have a sound emission surface arranged on the side surface of a case (1) so that a sound can be emitted in all circumferential directions of the sound emission and collection device. Each of the microphones (12) is arranged with the sound collection direction set in the center direction of the case (1). The microphone (12) and the speaker (11) have directivities opposing to each other. Accordingly, it is possible to minimize a wraparound sound from the speaker (11) to the microphone (12). Moreover, since the speaker (11) and the microphone (12) are arranged on circumferences of concentric circles, it is possible to obtain a compact configuration.
