Your message has been received. Thank you.
It is difficult to understand your inquiry of 56mm 8ohm waterproof speaker which can handle 102db， because through our vast experience， it is almost impossible in technology. Can you supply us with your sample？ If so， it would be big help to this project.
Hope we could work together.
Yours faithfully，
此邮件各处有很多缺点，首先语句呆板，严重的“生意腔”使邮件毫无生气，句子长而乱，含义模糊。没有提供足够的资料来支持自己的论点。更糟糕的是，措辞冒昧，极不礼貌。针对这些不足，我们再来看一下另一个版本。
修改以后：
====================
