Acousto-optic control circuit of multi-language toy car

Abstract

The invention discloses an acousto-optic control circuit of a multi-language toy car. The acousto-optic control circuit of the multi-language toy car is characterized by comprising a control chip U1, input circuits, a filter circuit and an output circuit, and the input circuits, the filter circuit and the output circuit are connected with the control chip; the input circuits comprise a language switching control circuit and a sound production control circuit. The acousto-optic control circuit of the multi-language toy car is ingenious in design, can control the output circuit to produce light and sound through the control chip, achieves a function of pronunciation switching among Chinese, English and Russian, during playing, and can also set light emitting and sound production effects, such as producing corresponding sound and performing corresponding light flashing according to actions of door opening of the toy car, through the input circuits; vividness and interestingness can be obtained, a lively atmosphere can be improved, the sense of dullness of a player can be avoided, playability and interestingness of the toy can be remarkably improved, and good entertainment can be obtained.

Description

technical field [0001] The invention relates to toys, in particular to a sound and light control circuit for a toy car. Background technique [0002] At present, all kinds of children's toys are mostly made by simulation means, such as toy airplanes, toy cars, etc. These toys are very similar to real products in real life in general shape, structure and local details, and can cultivate children's recognition of objects. Ability, is conducive to the development of children's early intelligence. [0003] Although there are many types and shapes of existing toy cars on the market, the main structure is nothing more than the body, chassis, wheels and driving mechanism, which are generally controlled by remote control and powered by batteries, which drive the motor to drive the car through a series of transmission devices. The movement is converted into the rotation of the wheels, so that the toy vehicle has the same effect as a real car. In order to improve the attractiveness o...
