[0034] Refer to Figure 4 and Figure 6 , the present invention provides a head-mounted display device, including:

[0035] A first temple housing 11, on which a first mounting groove 111 and a sound outlet hole 112 are provided;

[0036] A second temple housing 12, which is mounted on the first temple housing 11; and

[0037] The loudspeaker 20 is mounted on the side wall of the first mounting groove 111 and is spaced from the bottom wall of the first mounting groove 111, so that the loudspeaker 20, the side wall of the first mounting groove 111 and the bottom wall of the first mounting groove 111 enclose a sound outlet cavity 11a, and the sound outlet hole 112 is communicated with the sound outlet cavity 11a.

[0038] The head-mounted display device in the technical solution of the present invention includes a first temple housing 11, a second temple housing 12 and a loudspeaker 20. The first temple housing 11 is provided with a first mounting groove 111 and a sound outlet hole 112. The second temple housing 12 is mounted on the first temple housing 11. The loudspeaker 20 is hermetically connected to the side wall of the first mounting groove 111 and is spaced from the bottom wall of the first mounting groove 111, so that the loudspeaker 20, the side wall of the first mounting groove 111 and the bottom wall of the first mounting groove 111 enclose a sound outlet cavity 11a. Among them, the sound outlet hole 112 is communicated with the sound outlet cavity 11a. Since the loudspeaker 20 is hermetically connected to the side wall of the first mounting groove 111, the sound outlet cavity 11a is a closed cavity, so that the sound emitted by the loudspeaker 20 can only be emitted through the sound outlet hole 112, thereby reducing the sound leakage of the loudspeaker 20, improving the acoustic performance, and improving the user experience.

[0039] Further, the sound outlet hole 112 is located on the side of the first temple housing 11 facing the human ear, that is, the lower end surface of the first temple housing 11. In this way, the distance between the sound outlet hole 112 and the ear is shortened. On the one hand, the sound output effect and the user experience are increased; on the other hand, the distance between the sound outlet hole 112 and the ear is relatively close, which also reduces the spread range of the loudspeaker 20, thereby increasing the privacy of the head-mounted display device and improving the user experience.

[0040] Further, the head-mounted display device can be an AR glasses, a VR glasses, an MR glasses, etc.

[0041] In this embodiment, the head-mounted display device further includes an annular mounting plate 113. The annular mounting plate 113 is connected to the first temple housing 11, and the annular mounting plate 113 and the first temple housing 11 enclose the first mounting groove 111. An installation protrusion 114 is provided on the inner peripheral wall of the annular mounting plate 113. The installation protrusion 114 extends along the circumference of the annular mounting plate 113. The loudspeaker 20 is mounted on the inner peripheral surface of the annular mounting plate 113, and the loudspeaker 20 abuts against the side of the installation protrusion 114 facing the second temple housing 12.

[0042] By means of the installation protrusions 114, the fixing effect of the speaker 20 is further enhanced, reducing the possibility that the speaker 20 drops to the bottom wall of the first installation groove 111 due to the failure of pasting, thereby ensuring the stability of the acoustic performance of the speaker 20 and further extending the service life of the head-mounted display device.

[0043] Furthermore, a plurality of installation protrusions 114 are provided at intervals. The plurality of installation protrusions 114 extend in the same direction and are located in the same plane.

[0044] In this embodiment, the head-mounted display device includes a sound outlet mesh cloth 34. A pasting groove 115 is provided on the first temple shell 11. The pasting groove 115 is located at the bottom wall of the first installation groove 111. The sound outlet mesh cloth 34 is disposed opposite to the sound outlet hole 112. Two sides of the sound outlet mesh cloth 34 are respectively pasted to the side wall of the first installation groove 111 and the side wall of the pasting groove 115. In this embodiment, one end of the sound outlet hole 112 and the bottom wall of the first installation groove 111 are substantially in the same plane, that is, the height difference therebetween is small, so that the pasting surface of one end of the sound outlet mesh cloth 34 close to the bottom wall of the first installation groove 111 is small. Therefore, by providing the pasting groove 115 on the bottom wall of the first installation groove 111, the pasting area of the sound outlet mesh cloth 34 is increased, thereby increasing the bonding strength and stability of the sound outlet mesh cloth 34. Thus, the possibility that dust and other sundries enter the sound outlet cavity 11a through the sound outlet hole 112 is reduced, thereby improving the stability of the speaker 20 and extending the service life of the head-mounted display device.

[0045] Certainly, in other embodiments, the height difference between the sound outlet hole 112 and the bottom wall of the first installation groove 111 is large, that is, one end of the sound outlet mesh cloth 34 facing the bottom wall of the first installation groove 111 still has a large pasting area with the side wall of the first installation groove 111. In this case, the pasting groove 115 may not be provided.

[0046] Optionally, the speaker 20 is hermetically pasted to the inner peripheral surface of the annular mounting plate 113. The sealing effect is good, the fixing effect is strong, the pasting life is long, and the cost is low by means of pasting.

[0047] Refer to Figure 4, preferably, the corners of the inner side of the annular mounting plate 113 are chamfered, so that a glue storage groove 116 is formed between the corners of the annular mounting plate 113 and the outer peripheral surface of the speaker 20. By chamfering the corners of the inner side of the annular mounting plate 113, since the outer peripheral surface of the speaker 20 is hermetically adhered to the inner wall surface of the first mounting groove 111, the size of the speaker 20 is approximately the same as that of the first mounting groove 111. Therefore, the speaker 20 needs to be accurately aligned before being placed into the first mounting groove 111. After chamfering the corners, the opening of the first mounting groove 111 is increased. Thus, the speaker 20 only needs to be roughly placed at the opening of the first mounting groove 111, and then it can accurately slide down into the first mounting groove 111 through the chamfered corners, which facilitates the accurate installation of the speaker 20. On the other hand, there is always a certain gap between the outer peripheral surface of the speaker 20 and the inner peripheral surface of the first mounting groove 111. Therefore, the glue storage groove 116 formed between the chamfered corners and the outer peripheral surface of the speaker 20 further seals the speaker 20 and the first mounting groove 111, thereby improving the sealing effect of the speaker 20, reducing the leakage of the sound of the speaker 20, and enhancing the user experience.

[0048] Referring to Figures 1 to 6 , in this embodiment, the head-mounted display device further includes a sound leakage cover 31. A second mounting groove 117 is provided on the first temple housing 11. The first mounting groove 111 is located in the second mounting groove 117. The sound leakage cover 31 is sealingly connected to the opening of the second mounting groove 117. A first sound leakage hole 121 is provided on the second temple housing 12. A second sound leakage hole 3121 is provided on the sound leakage cover 31, and the second sound leakage hole 3121 is communicated with the first sound leakage hole 121. By providing the sound leakage cover 31, the sealing effect after the speaker 20 is installed is further enhanced.

[0049] It can be understood that the principle of the speaker 20 is that an audio current enters the coil / voice coil of the speaker 20 to generate a magnetic field. This magnetic field interacts with the magnetic field of the magnet to generate a thrust or suction force, thereby driving the diaphragm of the speaker 20 to move and pushing the air to generate sound. That is, when the speaker 20 emits sound, it will drive the diaphragm to move, thereby driving the air in the first mounting groove 111 to contract and expand. Therefore, by providing the first sound leakage hole 121 and the second sound leakage hole 3121, the air pressure in the first mounting groove 111 is maintained stable, thus ensuring the normal operation of the speaker 20.

[0050] Referring to Figure 2 and Figure 7, Further, the head-mounted display device further includes a first sound-discharging mesh 32. The sound-discharging cover 31 includes a first plate body 311 and a second plate body 312. The second plate body 312 is provided with a bulge in the direction close to the second temple housing 12. The second sound-discharging hole 3121 is provided in the second plate body 312. The first sound-discharging mesh 32 is hermetically adhered between the second plate body 312 and the second temple housing 12. By arranging the second plate body 312 to bulge in the direction close to the second temple housing 12, the first sound-discharging hole 121 and the second sound-discharging hole 3121 are directly communicated, thereby reducing the leakage of air flow to other parts of the first temple housing 11 and / or the second temple housing 12, and further increasing the effect of balancing air pressure.

[0051] Of course, in other embodiments, the first plate body 311 may also be flush with the second plate body 312, and the first plate body 311, the second plate body 312 and the second temple housing 12 are arranged at intervals. At this time, by arranging connecting columns on the second temple housing 12 and / or the second plate body 312, the first sound-discharging hole 121 and the second sound-discharging hole 3121 are directly communicated through the connecting columns.

[0052] Optionally, a limiting groove 3122 is provided on the side of the second plate body 312 facing the second temple housing 12. The first sound-discharging mesh 32 is hermetically adhered in the limiting groove 3122. By arranging the first sound-discharging mesh 32, other sundries such as dust in the external air are reduced from blocking the first sound-discharging hole 121 and / or the second sound-discharging hole 3121, thereby increasing the sound-discharging effect of the head-mounted display device and further improving the service life of the head-mounted display device. Further, by arranging the limiting groove 3122, the loosening of the first sound-discharging mesh 32 driven by the long-term disturbance of the air flow is prevented, and further the fixing effect of the first sound-discharging mesh 32 is increased.

[0053] If the air flow in the sound-discharging cover 31 leaks, it is easy for the air flow to flow between the first temple housing 11 and the second temple housing 12, and further it is easy for the connection part between the first temple housing 11 and the second temple housing 12 to become loose. Therefore, in this embodiment, a dispensing groove 118 is provided on the first temple housing 11, and the dispensing groove 118 is located at the opening of the second installation groove 117, so that the sound-discharging cover 31 is hermetically adhered to the opening of the second installation groove 117. By arranging the dispensing groove 118, on the one hand, it is convenient for the sound-discharging cover 31 to be connected by dispensing and sealing, and on the other hand, the dispensing groove 118 can also form a groove for storing glue after the sound-discharging cover 31 is hermetically connected, thereby increasing the sealing effect of the sound-discharging cover 31.

[0054] Refer to Figure 2 and Figure 6, in this embodiment, a third sound leakage hole 119 is provided on the first temple housing 11. The third sound leakage hole 119 communicates with the second mounting groove 117. The first sound leakage hole 121 is located on the side of the second temple housing 12 facing the first temple housing 11, and the third sound leakage hole 119 is located on the side of the first temple housing 11 close to the second temple housing 12. Through the first sound leakage hole 121 and the third sound leakage hole 119, the air pressure inside the sound leakage cover 31 is kept consistent with the outside world from multiple directions, thereby increasing the sound leakage effect, improving the sound output effect of the speaker 20, and further improving the user experience.

[0055] Furthermore, the first temple housing 11 and the second temple housing 12 are detachably connected. Specifically, corresponding mounting holes can be provided on the first temple housing 11 and the second temple housing 12 respectively, and then the first temple housing 11 and the second temple housing 12 are screwed together through screw connectors; of course, corresponding snap structures can also be provided on the first temple housing 11 and the second temple housing 12 for snap connection, such as hooks and slots; furthermore, ribs can be provided on the outer peripheral surface of the first temple housing 11, and then the second temple housing 12 is connected to the first temple housing 11 in an interference fit manner through the ribs. These detachable connection structures are simple, easy to install, stable and reliable, and have low costs.

[0056] By detachably connecting the first temple housing 11 and the second temple housing 12, it is convenient to disassemble the first temple housing 11 and the second temple housing 12, thereby facilitating the maintenance of the head-mounted display device and further increasing the service life of the head-mounted display device.

[0057] The above are only optional embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
