PROBLEM TO BE SOLVED: To provide a technology for expressing a more accurate position of an obstacle to own vehicle by sound while suppressing an increase in installation places of speakers in a passenger compartment.SOLUTION: An obstacle notification device 10 is provided with a speaker array 145 having a plurality of speakers installed in a passenger compartment of a vehicle. The obstacle notification device 10 acquires obstacle information for specifying physical relationship of the vehicle 100 and an obstacle (more specifically, direction of the obstacle and distance to the obstacle) and has a speaker array device 14 output acoustic beams of notification sound arranging sound sources in positions according to that physical relationship. For this purpose, the obstacle notification device 10 sets a parameter for having notification sound signals frequency shifted at a shifting amount according to the obstacle information to a signal processing unit 13 and parameters for specifying amplification factor for outputting sound beams of notification sound at a volume according to the obstacle information to each of power amplifiers 144A to 144P.SELECTED DRAWING: Figure 6

    【課題】車室におけるスピーカの設置箇所の増大を抑えつつも、自車両に対する障害物のより正確な位置を音によって表現するための技術を提供する。【解決手段】障害物報知装置10は、車両の車室に設置された複数のスピーカを有するスピーカアレイ145を備える。障害物報知装置10は、車両100と障害物との位置関係(より具体的には、障害物の方向及び障害物までの距離)を特定する障害物情報を取得し、その位置関係に応じた位置に音源を配置させた報知音の音響ビームを、スピーカアレイ装置14に出力させる。そのために、障害物報知装置10は、障害物情報に応じたシフト量で報知音信号を周波数シフトさせるためのパラメータを信号処理部13に、障害物情報に応じた音量で報知音の音響ビームを出力させるための増幅率を指定するパラメータをパワーアンプ144A〜144Pの各々に設定する。【選択図】図6
