PROBLEM TO BE SOLVED: To prevent a worker in a cabin of a combine from becoming difficult to listen to sound of an audio device due to noise of an engine and work device.SOLUTION: An in-cabin volume automatic adjustment system of a combine comprises: a plurality of speakers 13a, 13b arranged at positions surrounding a worker sitting in an operation seat 9 in a cabin 7a from front, rear, right, and left in a plane view; a reaping/threshing sensor 5S; an engine rotation sensor 14S; and a control device 39 automatically increasing volume of the first speaker 13a, among the plurality of speakers 13a, 13b, arranged at a position far from an ear of a worker with respect to the second speaker 13b arranged at a position close to the ear of the worker when the reaping/threshing sensor 5S detects an engaged state of the clutch and the engine rotation sensor 14S detects predetermined high rotation speed.SELECTED DRAWING: Figure 3

    【課題】コンバインのキャビン内の作業者がエンジンや作業装置の騒音でオーディオ装置の音が聞き辛くなることを防ぐ。【解決手段】キャビン(7a)内の操縦席(9)に着座する作業者を平面視で前後左右から取り囲む位置に配置した複数のスピーカ(13a13b)と、刈取・脱穀クラッチセンサ(5S)と、エンジン回転センサ(14S)とを設け、刈取・脱穀クラッチセンサ(5S)がクラッチの入り状態を検出し、エンジン回転センサ(14S)が所定の高回転速度を検出した場合に、複数のスピーカ(13a,13b)の内、作業者の耳から遠い位置に設けられている第1スピーカ(13a)の音量を、作業者の耳に近い位置に設けられている第2スピーカ(13b)の音量よりも自動的に大きくする制御装置(39)を設ける。【選択図】図3
