Y PIN / Earphone


Separation of the earphones.
Ear speakers which normally are used in life are divided into two parts.
One is a wire line part connected to ear speakers known as ‘Y’ shape and another is a
connection to device such as MP3 or Smartphone.
However, the thin wire line could be all tangled up together and has a possibility to be
damaged by rubbing frequently.When one of the ‘Y’ shaped connections got damage,
we suffer economic burden and uncomfortable until getting new one.Therefore,
I suggest a solution of the problem that all joint on the ‘Y’ disassemble into three parts.
Here is an example of ear speakers I suggest.
