Adjustable headphone |
摘要 |
An adjustable headphone comprising a pair of self-adjusting earpieces interconnected by a headpiece that includes a stiff resilient headband assembly and a soft flexible headstrap resting against a wearer's head. The headstrap is anchored at least at one end to a corresponding sliding block movably joined with the headband assembly having a bifurcated gear rack on its inner surface. The sliding block is equipped with at least one spring-loaded detent coming in contact with the gear rack. The headband assembly forms with at least one earpiece a hollow ball-and-socket joint where the spherical driver cup works as a ball part of the joint, and it mates to the arm's inner spherical surface which is a socket part of the joint. This joint provides the earpiece substantial angular motion in all directions thus enabling it to adjust to any ear shape.
