Abstract
A telescopic structure of a headphone includes a headband, a cover, a slider, two damping elements and a cable. A front end of an inner surface of the headband defines a first concave surface. The cover is disposed to the front end of the inner surface of the headband. A front end of an internal surface of the cover is recessed inward to form a second concave surface. The second concave surface is corresponding to the first concave surface. The slider is disposed between the headband and the cover. The two damping elements are disposed to the first concave surface and the second concave surface, respectively. The two damping elements abut against two opposite areas of an outer surface of the slider. The cable is disposed between the headband and the cover.
