Abstract
A head mounted display device and a head mounted display assembly are disclosed in some embodiments of the present disclosure. The head mounted display device comprises a display body and a sound transmission member. The display body is configured to display an image. The sound transmission member is connected to the display body, and is provided with a sound amplification cavity, a mounting groove communicated with the sound amplification cavity and a sound outlet hole. The mounting groove is configured to accommodate an earphone. The technical solution of the present disclosure can further reduce sound leakage and reduce noise interference to the surrounding environment.
