Good evening, this is Bono.

With that being said, we had the opportunity to consider an earphone plug that could be mounted on the board.
I tried to find out what kind of shapes are available, but I couldn't find a comprehensive site.

I did a lot of research and put it all together because it's a good idea.

Looking at them, it seems that there are many different types, such as the shape of the legs or the MIC pin attached.

By the way, all of them can be procured on Alibaba.
As expected from Alibaba, a Chinese company, there seems to be an abundance of parts systems available.

An orthodox shape, with four legs that come out so that it can be mounted on a board.
The four terminals are broken down as follows: right, left, GND, and microphone.
