本文介绍一款由笔者自己设计的多用模拟仿声电路,该电路由一只运放集成电路为核心,具有电路简洁、调整简单容易、仿声效果好等特点。使用时,只需简单调节,即可模拟多种自然声音,特别擅长模拟各种警报声、鸟类叫声等,还可用作门铃、防盗报警器等。休闲时玩一玩,其乐无穷,给笔者的业余生活增色不少。 This article describes a multi-purpose analog Ionic circuit designed by the author himself, the circuit consists of an op amp IC as the core, with the circuit is simple, easy to adjust, imitation sound effect and so on. Use, simply adjust, you can simulate a variety of natural sounds, is particularly good at simulating a variety of alarm sounds, birds, etc., but also can be used as a doorbell, burglar alarm. Fun to play at leisure, fun, to my amateur life by a lot of color.
