PURPOSE:To provide the stick type speech generating tool with which a user learn a scale while playing. CONSTITUTION:This tool is equipped with a cylinder 10, grip bodies 12 and 14 which are provided at both its ends, a cord 54 which is provided penetrating the cylinder 10 while tensed by a spring 56, a bending sensor 52 which detects the bending of the cylinder 10 from tension operating on the cord 54, and a scale sound output part 82 which outputs a corresponding scale sound based on the output of the bending sensor 52, and this scale sound output part 82 is equipped with an A/D converting circuit 64 which converts the detection output of the bending sensor 52 from analog to digital, a matrix switch 66 which outputs data corresponding to the output data of the A/D converting circuit 64 each time a trigger switch is pressed, and a scale generating IC 70 which outputs a corresponding scale signal for a certain time each time the data is inputted; and when the cylinder 10 is bent, the cord 54 shrinks to vary the shrinkage length of the spring 56, the detection output of the bending sensor 52 varies, and the scale sound generating IC 70 outputs a corresponding scale signal. |
