Detailed Description

The utility model will be further elucidated and described with reference to the embodiments and drawings of the specification:

referring to fig. 1, an angle-adjustable headphone includes a head band 10, a headphone head 20, and an adjustable connection structure 30 disposed between the head band 10 and the headphone head 20.

Referring to fig. 2 and 3, the adjustable connecting structure 30 includes a connecting arm 31 formed at an end of the head band 10, a connecting shaft 32 disposed at a distal end of the connecting arm 31, and a shaft hole 33 opened at a middle portion of a sidewall of the earphone head 20. The connecting shaft 32 is rotatably disposed in the shaft hole 33.

Wherein, connecting arm 31 one end is in earphone head 20 lateral wall top, and the other end is pressed close to earphone head 20 lateral wall edge bending type extends to shaft hole 33 department, connecting axle 32 lateral wall is outstanding to form spacing arch 321, breach 331 is seted up to shaft hole 33 lateral wall, spacing arch 321 stretches out from breach 331, in order to restrict earphone head 20's angle of adjustment.

One end of the connecting arm 31 is located above the side wall of the earphone head 20, the other end is bent and extended to the position of the shaft hole 33 close to the edge of the side wall of the earphone head 20, and the shaft hole 33 is formed in the middle of the side wall of the earphone head 20. When the earphone is worn, the earphone head 20 is attached to the ears of a person, and in the process, the earphone head 20 rotates around the rotating shaft slightly, so that the comfort is improved. Spacing arch 321 follows the rotation, rotates to the maximum angle when spacing arch 321 rotates and the butt is at breach 331 lateral wall, through breach 331 and spacing protruding 321's cooperation promptly, restricts headphone 20's inclination to conveniently wear.

Earphone head 20 includes earphone shell 21 and connecting block 22, shaft hole 33 is seted up on earphone shell 21, connecting block 22 is fixed in the earphone and is pressed on locating connecting axle 32, breach 331 is seted up on connecting block 22.

Fixing holes 221 are formed in two ends of the connecting block 22, the middle of the connecting block 22 is arched, an arc-shaped groove is formed in the lower surface of the middle of the arched connecting block 22 and matched with the connecting shaft 32, and the connecting block connecting device further comprises a fastening piece which penetrates through the fixing holes 221 to fix the connecting block 22 in the earphone shell 21.

Referring to fig. 4, 5 and 6, the head band 10 includes a band body 11 and connecting portions 12 disposed at two ends of the band body, one end of the connecting arm 31 forms a rotating shaft 311, and further includes a connecting shell 40 having an accommodating cavity, the connecting portion 12 extends into and is fixed at one end of the accommodating cavity, and the rotating shaft 311 is rotatably disposed at the other end of the accommodating cavity.

Connect the protruding card protruding 41 that forms of shell 40 inner wall, annular clamping groove 312 is formed to the pivot 311 lateral wall, card protruding 41 stretches into annular clamping groove 312 in, realizes the rotatable coupling of pivot 311.
