Please tell me how to make an opaque shell

I made a rotating machine. The cost is about 10 dollars. http://customiem.blogspot.jp/2017/07/blog-post_22.html

thank you for the advice. But I am not worried. Because other earphones were okay as well.

It is to prevent the air spring effect of the dynamic driver.

SR 32453 (full range) + dynamic driver (woofer). Face plate is fluorescent color. The sound quality is very warm. SR series are low cost and high performance.

+ - is your choice. If you connect the center tap to +, you have to connect the other to -. If you connect the center tap to -, you have to connect the other to +. + - should be aligned on the left and right. It is not an anode and a cathode. Earphone is an alternating current.

I am using UV resin (cheap goods not medical grade). Because it has high fluidity, it is necessary to paint in multiple times.

I bought SR 32453. It is planned to merge with dynamic driver (purchased with aliexpress). I think SR 32453 does not require a filter. Am I wrong?

Thank you very much! I will report it when it is completed

Hello everyone. My hobby is to make an ear monitor. I own "ED29689" and "CI22955". I would like to copy "JH Audio JH5 pro". Please tell me the capacitor I should use. The shell has already been completed.
