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.
HUIZHOU YEMING ELECTRONIC
This one also has four legs, also right, left, GND, and microphone.
The external form is slightly smarter.
RUI YING ELECYRONIC Slightly different shape. However, it is also a four-legged type.
I checked and the link was broken. Is it no longer for sale?
Dongguan Dajiang Electronics Co.
Compact 4-pole type.
It is unclear how it is used, but it also has this shape.
Fairly compact 4-pole type. This seems to work.
There are surface mount types and so on.
Alibaba is recommended for its wide variety. China is the original home, but there is a Japanese version as well.
