Abstract
An earphone device includes first and second earphone bodies into which respective electro-acoustic transducers are built; first and second cables, one end of each of which is connected to the respective earphone body and within each of which a switch member to be turned on by one-way press is disposed over a predetermined range along the length direction of the cable so that the cable has switch functions; wherein a switch is shunted into two switches by the first and second cables, portions of the first and second cables having switch functions are arranged one on top of the other, and an overlapped portion is unidirectionally pressed to simultaneously turn on the respective switches. In addition, a sound-reproducing system is configured by combining a mobile terminal which operates in conjunction with this earphone device.
