Abstract
An earphone system with temporary volume shifting function includes a speaker receiving audio signals and converting the received audio signals into sound, the speaker having a first end and a second end therein, a first resistor electrically connected to the first end of the speaker, and a switch configured between the first resistor and the speaker to control current flowing through the first resistor to the first end of the speaker. A first current flows through the speaker to output a first volume from the speaker when the switch is deactivated by a user who does not operate the switch, and a second current flows through the speaker to output a second volume from the speaker when the switch is activated by the user who operates the switch, and the second volume is greater than the first volume.
