Referring to FIGS. 1-6, the head mounted electronic device 100 of the embodiment of the present invention includes a headband assembly 10 and an earphone 20. The headgear assembly 10 includes a spindle 12. The earphone 20 includes an earmuff housing 22, a slider 24, and an earmuff shield 26. The side wall of the ear cup housing 22 is provided with a avoiding hole 221 . The slider 24 and the earmuff shield 26 are located within the ear cup housing 22. The earmuff shield 26 is provided with a flap through hole 262. The rotating shaft 12 is rotatably threaded through the avoiding hole 221 and the flap through hole 262 and connected to the slider 24. The earmuff shield 26 blocks the avoidance hole 221 and connects the slider 24. The earmuff shield 26 includes a first flap 264 and a second flap 266. The first flap 264 and the second flap 266 are partially stacked, and the first flap 264 and the second flap 266 are relatively slidable so that The headgear assembly 10 adjusts the area of the earmuff shield 26 when the slider 24 is slid.

In the head-mounted electronic device 100 of the above embodiment, since the first flap 264 and the second flap 266 are partially stacked, the first flap 264 and the second flap 266 are opposite when the headband assembly 10 is rotated. Sliding to adjust the area of the earmuff shield 26, which reduces the movement of the earmuff shield 26, facilitates increasing the available space of the earphone 20, thereby facilitating the placement of other components on the earpiece 20.

In the related art, the arc length of the avoidance hole generally corresponds to a central angle of about 90 degrees, and the rotation angle of the headband assembly is also about 90 degrees. While the existing earmuff blank is a single-layer earmuff blank, the single-layer earmuff blank needs to be designed to be 180 degrees in order to always cover the avoidance hole during the rotation of the headgear assembly. The length of the left and right arcs makes it necessary to reserve a moving space of about 270 degrees in the earphone for the movement of the single-layer earmuff block, so that the available space of the earphone is small. In the embodiment of the present invention, the earmuff shield 26 includes a first flap 264 and a second flap 266 which are partially stacked, and the first flap 264 and the second flap 266 are relatively slidable so that the headband assembly When the slider 24 is driven to slide, the area of the earmuff block 26 is adjusted, so that the moving space of the ear cup 62 can be reduced.

It can be understood that the number of the first flaps 264 can be one, two or more. The number of second single sheets 266 may be one, two or more.

It should be noted that the flap through hole 262 may be disposed on the first flap 264 or the second flap 266. When the flap through hole 262 is disposed in the first flap 264, the number of the first flaps 264 is one, and the number of the second flaps 266 may be one, two or more. When the flap through hole 262 is disposed in the second flap 266, the number of the second flaps 266 is one, and the number of the first flaps 264 may be one, two or more.

Specifically, referring to FIG. 2-3 , in one embodiment, the flap through hole 262 is disposed in the first flap 264 . The number of the first flaps 264 is one, and the number of the second flaps 266 is two. When the slider 24 slides, the first flap 264 can be driven to slide, and the second flap 266 slides relative to the first flap 264, so that the second flap 266 can be contracted inside the first flap 264 or A flap 264 is relatively extended.

Referring to FIG. 4, in one embodiment, the flap through hole 262 is disposed in the first flap 264. The number of the first flaps 264 is one, and the number of the second flaps 266 is four. Two second flaps 266 are stacked on the left end of the first flap 264, and two second flaps 266 are stacked on the right end of the first flap 264. When the slider 24 slides, the first flap 264 is slid, and the second flap 266 is slid relative to the first flap 264, so that the second flap 266 can be contracted. The inside of the first flap 264 or the first flap 264 extends away.

In certain embodiments, the ear cup housing 22 defines a limit groove 223. The second flap 266 is provided with a finite flange 2662. The limiting flange 2662 extends into the limiting slot 223. The limit groove 223 is configured to define a movement stroke of the first flap 264 and the second flap 266 by the limit flange 2662.

Thus, the movement of the first flap 264 and the second flap 266 can be defined by the limit flange 2662 so that the first flap 264 and the second flap 266 can cover the avoidance hole 221 during the sliding process. .

It can be understood that, during the sliding process of the second flap 266, the limiting flange 2662 can slide in the limiting slot 223. When the limiting flange 2662 reaches the leftmost or rightmost end of the limiting slot 223, the limiting slot The 223 blocks the limit flange 2662 to define the movement of the limit flange 2662, thereby defining the movement stroke of the first flap 264 and the second flap 266.
