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.

Abstract: The present disclosure provide a far-field muffling method for a head-mounted device, apparatus and system, which is applied to the head-mounted device. The head-mounted device comprises a first speaker, a second speaker, and further comprises a monitoring microphone. The method comprises: receiving a monitoring sound signal picked up by the monitoring microphone during operations of the first speaker and the second speaker; judging whether the monitoring sound signal satisfies a preset requirement, and if yes, ending; if not, determining a current first target compensation signal and a current second target compensation signal from preset various compensation signals; compensating the first speaker by using the first target compensation signal, compensating the second speaker by using the second target compensation signal, and returning to the receiving a monitoring sound signal picked up by the monitoring microphone.
