Abstract

The invention relates to an infrared inductive music playing toy. The traditional music playing toys lack interaction and are difficult to make improvisation. A shell part of the infrared inductive music playing toy comprises a light transmission cover, a light shield cover and a base; the light transmission cover is fixedly wrapped at the external surface of the light shield cover; n photoelectric switch holes are arranged in a matrix on the light shield cover; the base is in a hollow arch structure; the light shield cover and the base enclose to form a working cavity; each part of an electric control part is arranged in the working cavity, and the electric control part comprises a horn, a battery, a circuit board, a tuning chip, n photoelectric switches and n indicating lamps; the n photoelectric switches are divided into five groups, and the photoelectric switches forming one group can have the choice of positions on the light shield cover; and each group of the photoelectric switches are connected in parallel on the circuit board and then connected with a signal input end of the tuning chip, and the photoelectric switches of a same group trigger a same tone. The infrared inductive music playing toy changes the playing mode from striking keys to slide fingers by utilizing the photoelectric induction, so that the playing is simpler and easy to learn, is smooth and has grace.
