Abstract
A head-mounted display device includes a display unit projecting an image beam to user's eyes, thus enabling the user to see an enlarged virtual image, a headphone unit configured to transmit sound information to user's ears, and a connecting unit. The connecting unit is substantially C-shaped and defines a C-shaped opening. A middle portion of the connecting unit couples to the display unit. Two opposite sides of the C-shaped opening of the connecting unit couples to the headphone unit. The connecting unit includes an outer frame, a connecting assembly, and an inner frame. The connecting assembly includes at least two independent connecting members. The connecting assembly couples to the outer frame. The inner frame couples to the connecting assembly, and portions near the two opposite sides fix to the outer frame, thus sandwiching the connecting assembly between the inner frame and the outer frame.
