In the present invention, when the headphone is not worn, the switching unit conducts the input signal to the amplifying unit by connecting the input terminal and the amplifying unit, and the amplifying unit amplifies the input signal and outputs it through the output unit, thereby spreading the output sound in free space. To function as a speaker. On the other hand, when wearing the headphones, the switching unit blocks the input terminal and the amplification unit outputs the input signal to the output unit through the general path, thereby serving as a receiver function to output sound only in the close contact portion of the headphones.

As such, the present invention automatically switches between the speaker function and the receiver function according to whether the headphones are worn without additional function switching and selection.
