Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 5, a telescopic headphone comprises a headband 1 and a headphone shell 2, wherein a connecting arm 3 which is telescopic relative to the headband 1 is arranged between the headphone shell 2 and the headband 1, a sliding elastic sheet 4 fixed in the headband 1 is slidably sleeved on the connecting arm 3, and at least two adjusting grooves 31 are distributed on the connecting arm 3 to be matched with the sliding elastic sheet 4; an elastic lug 41 matched with the adjusting groove 31 is arranged in the sliding elastic sheet 4; the elastic bumps 41 are made of plastic; the adjusting groove 31 and the elastic lug 41 are respectively provided with adaptive arc-shaped curved surfaces; the side edge of the sliding elastic sheet 4 is provided with an elastic clamping opening 42; the connecting arm 3 is made of aluminum alloy.

A limiting structure 32 which limits the displacement of the sliding elastic sheet 4 extends from the end part of the connecting arm 3; when the sliding elastic piece 4 abuts against the limiting structure 32, the length between the headband 1 and the earphone shell 2 is the longest.

When the headband support is used, a user only needs to push and pull the connecting arm 3, the connecting arm 3 slides relative to the sliding elastic sheet 4 fixed in the headband 1, and the connecting arm 3 extends out or retracts relative to the headband 1 because the sliding elastic sheet 4 is fixed in the headband, until the sliding elastic sheet 4 moves into the designated adjusting groove 31 on the connecting arm 3 through the elastic bump 41, and telescopic adjustment is completed.

In summary, the present invention has been made to practical samples according to the description and the drawings, and after a plurality of use tests, the utility model can be proved to achieve the expected purpose, and the practical value is undoubted. The above-mentioned embodiments are only used to conveniently illustrate the present invention, and are not to the limit of the present invention in any form, and any person who knows commonly in the technical field has, if not in the scope of the technical features of the present invention, utilize the present invention to make the equivalent embodiment of local change or modification, and not to break away from the technical features of the present invention, and all still belong to the technical features of the present invention.
