摘要
针对传统电子琴体积较大,携带不便且依赖电源等问题,设计了一款基于太阳能的触感钢琴。该触感钢琴采用STC89C51芯片作为主控芯片,配置了防过充保护电路、降压电路、51芯片最小系统、触控开关控制电路、蜂鸣器发声电路,可以通过太阳能板为蓄电池充电,保证对电路长久供电,每个触碰开关按下都会使蜂鸣器发出相应声音,并实现音乐演奏。设计的太阳能触感钢琴具有电路结构简单、易操作、性价比高、小巧方便携带、节能环保等优点,可以用于培养儿童对音乐的兴趣,灌输绿色环保理念,具有较高的推广价值。
Aiming at the problems of large size,inconvenient carrying and power dependence of traditional electronic organ,this paper designs a touch piano based on solar energy.The touch piano uses STC89C51 chip as the main control chip,equipped with anti-overcharge protection circuit,step-down circuit,51 chip minimum system,touch switch control circuit and buzzer sound circuit.It can charge the battery through the solar panel to ensure the long-term power supply to the circuit,each touch switch will make the buzzer sound and achieve music performance.The solar touch piano designed in this paper has the advantages of simple circuit structure,easy operation,high cost performance,small and convenient to carry,energy saving and environmental protection,etc,.It can be used to cultivate children’s interest in music,instill the concept of green environmental protection,and has a high promotion value.
