瞧瞧超声波驱蚊器的内部电路结构、分析下到底有无驱蚊效果
<div style="color: black; text-align: left; margin-bottom: 10px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">伴侣</span>送了我一个超声波驱蚊器，<span style="color: black;">第1</span>感觉做工还<span style="color: black;">能够</span>，塑料外壳是很厚实的！</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/da4c8f676f9442f08b531bc4c9a04629~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1723557916&x-signature=W8FthPfCUE98OYH%2FmLgx6%2BE1ybU%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">拆开看是<span style="color: black;">这般</span>的，电路<span style="color: black;">能够</span>分为两部分：</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/58e06467245340e8978f0338d3e33aa1~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1723557916&x-signature=WErhVpvVo2VbMQVlrHlH4zM68Yg%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">一部分是电源电路，220V进来经过阻容降压、四个二极管整流、25V47UF电容滤波、得到稳定直流电压！</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">第二部分<span style="color: black;">是由于</span>555芯片<span style="color: black;">形成</span>的震荡电路，产生的25KHZ的高频信号从第三脚输出接到压电陶瓷蜂鸣片，产生高频信号驱虫！</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">按照</span>实物画的线路图：</p>
<div style="color: black; text-align: left; margin-bottom: 10px;"><img src="https://p3-sign.toutiaoimg.com/pgc-image/79411aea3e824838aa378f4fd05d6bf1~noop.image?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1723557916&x-signature=dplDN5tXklzOMTcWoNt6IhY9%2BmA%3D" style="width: 50%; margin-bottom: 20px;"></div>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">这种电路驱蚊的原理<span style="color: black;">据述</span>是：发出类似公蚊子拍翅膀的超声波、<span style="color: black;">或</span>蚊子天敌：蜻蜓震翅发出的声音、蝙蝠发出的超声波，从而达到驱赶蚊子的目的。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">至于这个电路驱蚊效果好<span style="color: black;">欠好</span>，我那个<span style="color: black;">伴侣</span>说效果不大、感觉是忽悠！<span style="color: black;">不外</span>我还<span style="color: black;">无</span><span style="color: black;">运用</span>过，天冷了，找不到蚊子了。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">然则</span>我感觉这个电路发出的声音肯定很小，<span style="color: black;">由于</span>是超声波，人耳朵听不到，<span style="color: black;">因此</span>准备凑时间，把这个电路震荡频率给它降低，<span style="color: black;">瞧瞧</span>这个电路声音到底有多大。</p>

哈哈、笑死我了、太搞笑了吧等。
