摘要： A sound emission and collection device has a plurality of speakers (11) and a plurality of microphones. The speakers each have a sound emission surface arranged on the side surface of a case (1) so that sound can be emitted in all circumferential directions. The microphones (12) each are 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 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.

摘要： An audio apparatus has a housing including a tub-shaped recessed part having an upper surface and a wall surface formed on the upper surface. Microphones are circularly arranged in the vicinity of the wall surface inside the recessed part. Each microphone face toward a center direction of the recessed part and the upper surface so that a sound pick-up directivity is toward the center of the housing. A back side, opposite to the direction having the directivity of each microphone is open acoustically and is directed toward a direction higher than the wall surface of the tub-shaped recessed part.

摘要： A voice emitting and collecting device that is capable of picking up/outputting a voice emitted from a talker at a high S/N ratio by eliminating the influence of a diffracting voice despite a simple configuration is provided. A signal differencing circuit 191 outputs difference signals MS1 to MS4 between voice collecting beam signals MB11 to MB14 and voice collecting beam signals MB21 to MB24. A level comparator 195 selects the difference signal having a maximum level. A signal selecting circuit 196 selects voice collecting beam signals MB1x, MB2x of the difference signal MS that is selected/pointed by the level comparator 195. A subtracter 199 subtracts the voice collecting beam signal MB2x from the voice collecting beam signal MB1x, and output a resultant signal. Accordingly, main components of the diffracting voice can be removed from the voice collecting beam signal.

摘要： A sound enhancement system is configured such that sound emitting and collecting apparatuses 100 to 105 are connected to each other via a transmission line LT. The sound emitting and collecting apparatuses 100 to 105 are grouped into a master and a slave. The master sound emitting and collecting apparatus 100 generates a reference clock signal to be supplied to slave sound emitting and collecting apparatuses 101 to 105. The slave sound emitting and collecting apparatuses 101 to 105 form a sound collection beam signal in synchronization with the reference clock signal, and then output the resulting signal to the master sound emitting and collecting apparatus 100 without performing acoustic coupling suppressing process. The master sound emitting and collecting apparatus 100 collectively executes the acoustic coupling suppressing process to each sound collection beam signal to produce a sound emitting signal. The master sound emitting and collecting apparatus 100 outputs the sound emitting signal to the slave sound emitting and collecting apparatuses 101 to 105, each of which emits sound based on the sound emitting signal.

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.
