Embodiment Construction

[0011] The photoelectric induction musical instrument includes a shell part and an electric control part.

[0012] Such as figure 1 As shown, the housing part is composed of a light-transmitting cover 1 , a light shield 2 and a base 3 .

[0013] The light-transmitting cover 1 is a transparent shell formed of a plane, and the two sides of the central position of the light-transmitting cover 1 are symmetrically provided with concave slots 4 . The light shield 2 is a shell made of arc surface, and the two sides of the center position of the light shield 2 are symmetrically provided with outwardly protruding locking keys 5 . The radian of the light shield 2 is the same as that of the light transmission cover 1 , and the light transmission cover 1 is fixedly covered on the outer surface of the light shield 2 through the locking key 5 and the locking groove 4 . A side of the sunshade 2 near the sunshade 2 is provided with four indicator light holes 6 . There are 118 photoelectric...

Abstract

The invention relates to a photoelectric sensing musical instrument. A traditional music playing toy lacks interaction, and extemporaneous performance is difficult. The photoelectric sensing musical instrument has a housing part which comprises a light transmission cover, a light shield, and a pedestal. The light transmission cover fixedly coats an external surface of the light shield. The light shield is provided with n photoelectric light transmission holes which are in matrix arrangement. The pedestal is a hollow rectangular structure, and a working chamber is enclosed by the light shield and the pedestal. Each component of an electric control part is provided in the working chamber, and the electric control part comprises a loudspeaker, a cell, a circuit board, a melody chip, n photoelectric touch control switches and an indicating lamp. The n photoelectric touch control switches are divided into at least three groups, and positions of photoelectric touch control switches which form a group on the light shield are selected arbitrarily. Each group of photoelectric touch control switches is in parallel connection on the circuit board and is connected to a signal input terminal of a tuning chip, and a same group of photoelectric touch control switch triggers a same tone. According to the invention, by utilizing photoelectric sensing, a playing mode is changed to a mode of finger touch from a mode of pressing a keyboard, and a playing process is more easy and fluent.

Description

technical field [0001] The invention belongs to the field of musical instruments, and in particular relates to an instrument controlled by photoelectric induction for playing music. Background technique [0002] Traditional music playing toys generally need to trigger the switch of the music chip through the button to control the notes and music. Therefore, users are required to have certain music theory knowledge and playing skills in order to master the use of music toys. and play. It is difficult for beginners to play music smoothly, and the lack of interaction in the playing process makes it difficult to improvise. If it is played casually, it will only produce a messy noise. Contents of the invention [0003] The object of the present invention is to provide a kind of photoelectric induction musical instrument. [0004] The invention includes a shell part and an electric control part. The housing part is composed of a light-transmitting cover, a light shield and a...
