音乐集成电路作为一种新的电子元件问世以来,应用范围随着不断地开发日趋广泛。由于其灵敏性很高,耗电极微。再配上发声很灵敏的压电陶瓷片可以构成一个“微弱直流电流检测器”。通过发出的音乐声检验产生的电流,用于中学物理实验教学,取代教材中传统的一些方法,显得极为灵敏,有趣且新颖。本文谈谈音乐集成电路在中学物理实验教学中的几例应用。 Since the introduction of music integrated circuits as a new type of electronic component, the scope of application has become increasingly widespread with continuous development. Due to its high sensitivity, it consumes micro electrodes. Paired with a very sensitive piezoelectric ceramic chip can constitute a “weak DC current detector.” The current produced by the test of the sound of music is used in the teaching of physics experiments in middle school. It replaces some of the traditional methods in textbooks and is extremely sensitive, interesting and novel. This article talks about the application of music integrated circuit in physics experiment teaching in middle school.
