A kind of acousto-optic fishing rod shake sensing device, include: a shell has hollow structure, is made of the material of light-permeable； The shell is installed on one fishing rod of what with what； Wherein the shell is in pen tube shape, can avoid winding mutually with the fishline of fishing rod. In the one first lamp body position what shell,The light of the capable of emitting particular color of first lamp body is to prompt user； In the one second lamp body position what shell,The light of the capable of emitting particular color of second lamp body is to prompt user； Wherein the luminescent color of first lamp body and second lamp body is different； In the one inductor position what shell,The shake of the fishing rod is detected with what,And the logic default according to the shake information and the inductor detected selects one of them that it is enabled to shine from first lamp body and the second lamp body the two,And another one is enabled not shine； Therefore the light source that user can pass through first lamp body and second lamp body learns the shake state of the fishing rod easily,And then judge whether the fishing rod catches biology.一種聲光釣竿搖動感應裝置，包含：一殼體具有中空結構，由可透光之材質構成；該殼體用於安裝於一釣竿上；其中該殼體呈筆管狀，可避免與釣竿的釣線互相纏繞。一第一燈體位於該殼體內，該第一燈體可發出特定顏色的燈光以提示使用者；一第二燈體位於該殼體內，該第二燈體可發出特定顏色的燈光以提示使用者；其中該第一燈體及該第二燈體的發光顏色不同；一感應器位於該殼體內，用於偵測該釣竿的搖動，並依據所偵測到的搖動資訊及該感應器內定的邏輯從該第一燈體及該第二燈體兩者中選擇其中一者令其發光，並令另一者不發光；因此使用者可透過該第一燈體及該第二燈體的光源輕易地得知該釣竿的搖動狀態，進而判斷該釣竿是否釣到生物。
