这里介绍一个多音色机关枪声模拟器,它能模拟各种机关枪的声音,音色逼真,可用于各种机动玩具或用作录音模拟音响源。机枪声模拟器电路见图。它的核心元件是集成电路IC,型号为CW9561。CW9561是玩具专用的四声音乐集成电路,这里巧用它的两个选声端,即第2、第6两脚,使它们接入不同的高、低电平,以获得四种不同机枪声。
Here is a multi-tone machine gun simulator, which simulates the sound of various machine guns. The sound is realistic and can be used in a variety of mobile toys or as a recording analogue sound source. Machine gun simulator circuit shown. Its core component is integrated circuit IC, model CW9561. CW9561 is a toy dedicated four-tone music IC, where the clever use of its two optional end, that is, 2, 6 feet, so that they access different high and low to get four different machine gun sound .
