There are three movable spans for array distribution on Moving plate, and the rotation panel surface centre position is additionally provided with knob, the headset body left end
Face is equipped with sponge ring, and sponge ring is made of sound-absorbing sponge material, and the headset body where the sponge ring is equipped with fixed ring flat-plate,
Sponge ring is equipped with is equipped with pretension bolt, the earphone sheet with the matched fixed annular groove of fixed ring flat-plate, the sponge ring outside
Internal end face centre position is fixed with adjusting rod, and adjusting rod is threaded rod, and earphone column is arranged on adjusting rod, and earphone column is equipped with
With the matched threaded hole of adjusting rod, earphone column end is equipped with earphone heads, is to be threadedly coupled between earphone column and earphone heads.
As further program of the utility model：The hanging rod is curved rod, and is enclosed with silica gel sheath on the outside of hanging rod.
As further program of the utility model：Ventilative grid is equipped in the movable span.
As further program of the utility model：It is corresponding between the movable span and mounting hole.
As further program of the utility model：It is enclosed with layer of silica gel on the outside of the earphone heads.
Compared with prior art, the utility model has the beneficial effects that：The utility model is simple and reasonable for structure, works as activity
When hole is staggered with mounting hole position, headset body will constitute a closed structure, and then prevent external sound from being done
It disturbs, when movable span is corresponding with mounting hole, then headset body is not then a closed structure, and such people also can listen outer
Boundary's sound, thereby realizes the switching of noise reduction, and then plays the role of noise reduction, is in addition screw thread between earphone column and earphone heads
Connection by Swivel earphone column, and then adjusts the extension elongation of earphone heads, to control the depth that earphone heads are inserted into ear,
Earphone heads can be rotated to most short, it, thus will not be because of being extruded in ear for a long time so that earphone heads are not contacted with ear
Ear is damaged in piece, it is highly practical.
