To provide a flight speaker, output position identification method, and output position identification program capable of adaptively identifying an output position to output sound.SOLUTION: A flight speaker 1 firstly outputs inspection sound while flying on a linear first route R1 which connects a position of a sound collection microphone M arranged inside a concert hall P1, and identifies the optimum volume position where the volume of reception sound collected by the sound collection microphone M becomes an expected volume. The flight speaker outputs inspection sound while flying on a circular arcuate second route R2 where a distance between the identified optimum volume position and the position of the sound collection microphone M is defined as a radius, and identifies an output position where a sonic waveform of the reception sound from the sound collection microphone M becomes an expected sonic waveform. When the output position is identified, there is no necessity to prepare a model or a map on which a shape, wall and ceiling positions, and audience seat positions or the like of the concert hall P1 where the flight speaker 1 is to be arranged are reflected. Thus, the output position can be adaptively identified in response to a space where the flight speaker 1 is to be arranged.SELECTED DRAWING: Figure 3

    【課題】音を出力する出力位置を適応的に特定できる飛行スピーカ、出力位置特定方法および出力位置特定プログラムを提供すること。【解決手段】飛行スピーカ1は、まず、コンサートホールP1内に配置された集音マイクMの位置を結ぶ直線状の第1経路R1を飛行しながら検査音を出力し、集音マイクMで集音された受信音の音量が期待音量となる最適音量位置を特定する。特定された最適音量位置と集音マイクMの位置との距離を半径とする円弧状の第2経路R2を飛行しながら、検査音を出力し、集音マイクMからの受信音の音波形が期待音波形となる出力位置を特定する。出力位置の特定において、飛行スピーカ1を配置するコンサートホールP1の形状や壁や天井の位置、客席の位置等が反映されたモデルや地図を用意する必要がない。これにより、出力位置を、飛行スピーカ1が配置される空間に応じて適応的に特定できる。【選択図】図3
