Technical field

The present invention relates to the field of virtual reality VR, and more particularly to a head mounted display.

Background technique

The virtual reality VR field is an emerging industry that uses computer graphics systems and various display and control interface devices to provide an immersive feel for interactive, three-dimensional environments generated on computers. The immersion feeling is mainly realized by a virtual reality glasses device, and the head-mounted display is a widely used virtual reality glasses device.

In the prior art, everyone pays more attention to the design and development of the visual effects of the head-mounted display, and does not have much consideration for the user's experience in wearing still has many problems. For example, the existing head-mounted display is fixed to the user's head by a strap-type structure, and when fixed, the strap is closely attached to the ear, causing a pressure on the ear, which causes the user's ear after being worn for a long time. Discomfort can cause pain. Moreover, some of the existing head-mounted displays only have one audio output, but in order to achieve a visual and auditory resonance effect, sometimes the user is required to additionally wear the earphone device. However, the manner in which the head-mounted display and the earphone are simultaneously worn increases the pressure on the user's head and reduces the sense of experience. At the same time, in this case, the aforementioned straps also cause pressure on the earphone device that the user separately wears, further increasing the pressure on the ear of the earphone.

The experience in the VR field, whether it is VR games or VR 3D movies, is time consuming. The above problems in wear will undoubtedly affect the user experience. Therefore, how to improve the comfort of the user wearing the head-mounted display is particularly important.
