PURPOSE: A wire disconnection prevention earphone is provided to arrange a wire part of a solid conductor with a liquid, thereby overcoming disconnection of a wire. CONSTITUTION: A wire disconnection prevention earphone comprises an input part(110) which receives an electric signal from an external device such as a cell phone, computer, and MP3 player and a wire part(120) which transmits the received electric signal to a speaker part(130). The speaker part converts the electric signal from the wire part to a sound signal. The outer part of the wire part is arranged with an insulating material. The inner part of the wire part is arranged with an electrolyte for making an ion. The electrolyte in the inside of the wire part touches with the input part and speaker part. The wire part internally touches with the input part and speaker part. |
