| description | To provide a sound source direction detection system, a speaker set and a sound source direction detection device that can precisely detect the direction of a sound source inside or outside a vehicle without requiring any troublesome setting operation.SOLUTION: A sound source direction detection system has: a speaker group including at least one speaker attachable to a speaker fixation part in the cabin of a vehicle; a plurality of microphones installed at the speaker group; a microphone installation position acquisition part which specifies installation positions of the respective microphones based upon the installation position of the speaker fixation part, and obtains microphone installation position information representing the installation positions of the respective microphones; and a direction detection part which detects the direction of a sound source based upon microphone sound reception signals obtained by receiving a sound by the plurality of microphones, and the installation positions of the microphones represented with the microphone installation position information.SELECTED DRAWING: Figure 1
【課題】本発明は、煩わしい設定作業を要することなく、車両内又は車両外の音源の方向を精度良く検知することが可能な音源方向検出システム、スピーカセット及び音源方向検出装置を提供することを目的とする。【解決手段】本発明は、車両の室内のスピーカ固定部に取り付け可能な少なくとも１つのスピーカを含むスピーカ群と、スピーカ群に設置されている複数のマイクと、スピーカ固定部の設置位置に基づき、マイク各々の設置位置を特定し、マイク各々の設置位置を示すマイク設置位置情報を得るマイク設置位置取得部と、複数のマイクで夫々受音して得られたマイク受音信号、及びマイク設置位置情報にて示されるマイク各々の設置位置に基づいて音源の方向を検出する方向検出部と、を有する。【選択図】図１ |
