Abstract

A headphone includes an outer housing, a light guiding unit, two push buttons, a circuit board mounted in the outer housing, two switches mounted at the circuit board, and an inner housing covered to the outer housing. The outer housing has a peripheral wall, a button hole and an outer wall. An inner surface of the peripheral wall is defined as an inner periphery surface. An outer surface of the peripheral wall is defined as an outer periphery surface. The button hole penetrates through the inner periphery surface and the outer periphery surface. The outer wall is connected with the peripheral wall. An inner surface of the outer wall is defined as an interior surface. The light guiding unit is mounted in the outer housing, and the light guiding unit partially penetrates through the button hole. The two switches resist against the two push buttons.
