[0040] like Figures 1 to 4 As shown, this embodiment provides a head-mounted display device, which includes a frame 100 and two temple structures, each connected to opposite ends of the frame 100. Specifically, the head-mounted display device can be AR glasses. The temple structure includes a temple body 200, a mounting base 400, and a sound-emitting module 600. The mounting base 400 is disposed on the temple body 200 and has a first connector 300 and a second connector 500. The mounting base 400 is rotatably connected to the temple body 200 via the first connector 300. The sound-emitting module 600 is disposed on the mounting base 400 and connected to the second connector 500. The sound-emitting module 600 rotates relative to the mounting base 400 about its own axis via the second connector 500.
[0041] The rotation of the mounting base 400 causes the sound-generating module 600 to rotate, allowing the position of the sound-generating module 600 relative to the temple body 200 to be adjusted to accommodate the ear canal position of different people. In addition, the rotation of the sound-generating module 600 relative to the mounting base 400 enables the adjustment of the angle of the front and rear sound outlets on the sound-generating module 600, thereby ensuring that the user can hear a loud sound while also ensuring the user's privacy.
[0042] It should be noted that the sound-generating module 600 has a front cavity sound outlet 610 and a rear cavity sound outlet 620. Rotating the sound-generating module 600 can adjust the position of the front cavity sound outlet 610 and the rear cavity sound outlet 620 relative to the ear canal, thereby meeting the needs of volume and privacy.
[0043] The front cavity sound outlet 610 and the rear cavity sound outlet 620 are symmetrically arranged on the sound generating module 600 and are configured to form an acoustic dipole effect when the sound generating module 600 emits sound, so that the sounds emitted by the front cavity sound outlet 610 and the rear cavity sound outlet 620 cancel each other out at a distance.
[0044] To better accommodate the ear canal positions of different individuals, in some embodiments, the mounting base 400 is provided with a slide rail 410 extending along its length; the second connector 500 is slidably connected to the slide rail 410. This arrangement allows the sound-generating module 600 to move synchronously with the second connector 500, thereby enabling a wider range of relative positional changes between the sound-generating module 600 and the temple body 200, thus accommodating the ear canals of more diverse individuals. Figure 2 As shown, the slide rail 410 is a slide rail 410 formed on the mounting base 400, and the second connecting member 500 is slidably disposed in the slide rail 410. The slide rail 410 can constrain the movement trajectory of the second connecting member 500 and limit its extreme positions.
[0045] Specifically, the slide rail 410 has an elongated hole structure. To prevent the second connector 500 from separating from the mounting base 400 during relative sliding, in some embodiments, the second connector 500 includes a second connecting portion 510 and two second limiting portions 520 respectively located at both ends of the second connecting portion 510. The outer diameter of the second limiting portion 520 is larger than the outer diameter of the second connecting portion 510 and larger than the maximum width of the elongated hole. The second connecting portion 510 passes through the elongated hole, and the two second limiting portions 520 are located on the inner and outer sides of the mounting base 400, respectively. The second connector 500 can be a bolt or a nut, wherein the thread in the bolt forms the second connecting portion 510, the nut in the bolt forms one of the second limiting portions 520, and the nut forms the other second limiting portion 520.
[0046] Regarding the rotation of the sound-generating module 600, in some embodiments, the sound-generating module 600 is fixed to the second limiting part 520, and the second connecting part 510 can rotate around its own axis, that is, the second connecting part 510 can rotate within the elongated hole. To ensure that the sound-generating module 600 does not spontaneously rotate when no external force is applied, in some embodiments, a damping element is provided between the second connecting part 510 and the mounting base 400. The damping element can be a rubber sleeve or a friction pad. In other embodiments, the sound-generating module 600 is rotatably disposed on the second limiting part 520, and the second connecting part 510 is provided with a sliding plane that slides against the sidewall of the elongated hole, so the second connecting part 510 can only slide within the elongated hole.
[0047] In some embodiments, the second connector 500 has a rotation range of 360° relative to the mounting base 400. This rotation range allows the second connector 510 to be a cylindrical structure, which is simple in structure, easy to manufacture, and low in cost.
[0048] Considering cost and application scope, in some embodiments, the length of the slide rail 410 is less than or equal to 30mm. In other words, the second connecting part 510 can slide in the slide rail 410, and the maximum sliding distance is 30mm. The damping element between the second connecting part 510 and the mounting base 400 ensures that the second connecting part 500 remains stationary with the mounting base 400 when no external force is applied, ensuring that the angle of the sound-generating module 600 remains constant during use, thereby guaranteeing sound output quality.
[0049] Regarding the rotation of the mounting base 400, in some embodiments, the mounting base 400 is disposed on the outer side of the temple body 200; the temple body 200 has a first rotation hole 210, the mounting base 400 has a second rotation hole 420, and the first connector 300 includes a first connecting portion 310, which passes through the first rotation hole 210 and the second rotation hole 420. The first connecting portion 310 is fixedly connected to the temple body 200 and rotatably connected to the second rotation hole 420. This arrangement prevents the first connecting portion 310 from causing wear on the temple body 200, thus improving the service life of the temple body 200. Specifically, the hardness of the mounting base 400 is less than that of the first connecting portion 310 to minimize wear on the first connecting portion 310, resulting in lower replacement costs when the mounting base 400 wears out.
[0050] In other embodiments, the first connecting portion 310 can be fixed to the mounting base 400, and the first connecting portion 310 can be rotatably connected to the first rotating hole 210. In this embodiment, the hardness of the first connecting portion 310 is less than the hardness of the temple body 200 to avoid wear on the temple body 200. When the first connecting portion 310 wears out, the replacement cost is lower. Similarly, a damping element is provided between the first connecting portion 310 and the temple body 200 to ensure that the position between the mounting base 400 and the temple body 200 remains unchanged when no external force is applied, thereby ensuring that the position of the sound-generating module 600 remains unchanged during use to ensure sound output quality.
[0051] Regarding the specific structure of the first connector 300, in some embodiments, the first connector 300 further includes two first limiting portions 320 respectively disposed at both ends of the first connecting portion 310. The outer diameter of the first limiting portion 320 is larger than the outer diameter of the first connecting portion 310 and larger than the outer diameter of the first rotating hole 210. One of the two first limiting portions 320 is located inside the temple body 200, and the other is located outside the mounting base 400. This arrangement ensures the connection stability between the first connector 300 and the temple body 200. The first connector 300 may include bolts and nuts; the specific arrangement is the same as that of the second connector 500 and will not be described again here.
[0052] Combination Figure 3 and Figure 4As shown, the mounting base 400 rotates relative to the temple body 200 by an angle α, where 0° ≤ α ≤ 60°. The temple body 200 has a clearance portion 220. When the rotation angle α between the mounting base 400 and the temple body 200 is 0°, at least a portion of the second connecting member 500 is located within the clearance portion 220. The clearance portion 220 is formed in a groove on the lower side wall of the temple body 200. When the rotation angle α between the mounting base 400 and the temple body 200 is 0°, the second limiting portion 520 on the inner side of the mounting base 400 is located within the groove. This arrangement reduces the volume and weight of the temple body 200 and also contributes to the aesthetics of both the temple body 200 and the mounting base 400. The length of the groove along the length of the temple body 200 is greater than or equal to 30 mm to facilitate the sliding of the second connecting member 500.
[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
