[0060] Optionally, the flexible portion 412 has a first cavity portion, the rigid portion 411 has a second cavity portion, and the second cavity portion and the first cavity portion are connected and combined to form a sound cavity 416 .

[0061] In some embodiments of the present application, the rigid portion 411 is fixedly connected to the head-mounted component 2 or the device body 1 ; the end of the flexible portion 412 away from the rigid portion 411 is movably connected to the head-mounted component 2 to adjust the volume of the sound cavity 416 .

[0062] In the embodiment of the present application, by adjusting the relative position of the flexible portion 412 and the head-mounted component 2, the volume of the sound cavity 416 where the sound unit 42 is located can be adjusted, and then the audio of the speaker 4 can be adjusted to achieve the adjustment of the sound signal of the speaker 4.

[0063] Specifically, the rigid portion 411 and the head-mounted component 2 may be directly fixed by bonding or snap-fitting, or the rigid portion 411 may be directly fixed to the device body 1 by bonding or snap-fitting, and indirectly fixed to the head-mounted component 2.

[0064] Specifically, one end of the flexible portion 412 away from the rigid portion 411 is movably connected to the head-mounted component 2, so that the position of the end of the flexible portion 412 away from the rigid portion 411 relative to the head-mounted component 2 can be adjusted.

[0065] Specifically, the position of one end of the flexible portion 412 away from the rigid portion 411 relative to the headband component 2 is adjustable, so that the volume of the sound cavity 416 is adjustable, that is, the size of the resonance cavity where the sound-emitting unit 42 is located is adjustable, so that the audio of the speaker 4 is adjustable, and then the sound signal of the speaker 4 can be adjusted. Among them, the larger the resonance cavity, the greater the loudness in the low frequency band.

[0066] Specifically, the flexible portion 412 can be designed with reference to the design of a bellows, such as Figure 1 and Figure 2 As shown, the outer surface of the flexible portion 412 may be in a "wave shape" composed of a plurality of "Z"-shaped structures alternately arranged. Other situations may refer to the settings, and the embodiments of the present application do not make specific limitations on this.

[0067] In the embodiment of the present application, the volume of the sound cavity 416 can be changed by adjusting the expansion and contraction state of the flexible portion 412 , thereby adjusting the size of the resonance cavity and changing the sound effect of the sound-emitting unit 42 .

[0068] Furthermore, a first guide member 4121 is provided at one end of the flexible portion 412 away from the rigid portion 411 , and a second guide member 23 is provided at the head-mounted component 2 , and the second guide member 23 is slidably matched with the first guide member 4121 .

[0069] In the embodiment of the present application, the sliding cooperation between the first guide member 4121 and the second guide member 23 is utilized to drive the flexible portion 412 to extend and deform, thereby improving the structural stability of the head display device.

[0070] Specifically, the second guide member 23 can extend along the extension direction of the head-mounted component 2, so that the first guide member 4121 can move along the extension direction of the head-mounted component 2 to adjust the volume of the sound cavity 416.

[0071] Furthermore, if Figure 6 The head display device also includes a plurality of spaced-apart limiting members 24 ; the limiting members 24 cooperate with the first guide member 4121 to limit the first guide member 4121 .

[0072] In the embodiment of the present application, the limiting function of multiple limiting members 24 is utilized to limit the first guide member 4121, so that the volume size of the sound cavity 416 can be adjusted in multiple gears, and the audio of the sound unit 42 can be adjusted in multiple gears, which can adapt to the diverse needs of users.

[0073] Specifically, the limiting member 24 and the first guide member 4121 may be concave-convex matched, or may be snap-fit ​​matched, etc.

[0074] Furthermore, the first guide member 4121 is a slide rod and the second guide member 23 is a slide groove, or the first guide member 4121 is a slider and the second guide member 23 is a slide rail 4142, which can ensure the reliability and convenience of the sliding fit between the first guide member 4121 and the second guide member 23.

[0075] Specifically, combined Figure 1 , Figure 2 and Figure 6 As shown, a case where the first guide member 4121 is a slide bar and the second guide member 23 is a slide slot is illustrated, and other cases can be set with reference to the above.

[0076] In the embodiment of the present application, the second guide member 23 can extend along the extension direction of the rigid section 21 of the headgear component 2, so that the first guide member 4121 can slide along the extension direction of the rigid section 21. Figure 2 As shown, the extension direction of the rigid section 21 is the direction indicated by the arrow. Figure 2 to Figure 1 As shown, the first guide member 4121 slides to the left, the flexible portion 412 is compressed, and the volume of the sound cavity 416 is reduced, so that the resonance cavity is reduced, and the loudness of the speaker 4 in the low frequency band is smaller. Figure 1 to Figure 2 As shown, the first guide member 4121 slides to the right, the flexible portion 412 stretches, and the volume of the sound cavity 416 increases, so that the resonance cavity increases, and the loudness of the speaker 4 in the low frequency band is greater.

[0077] In some other optional embodiments of the present application, one end of the flexible portion 412 away from the rigid portion 411 is fixedly connected to the head-mounted component 2 or the device body 1, and the rigid portion 411 is movably connected to the head-mounted component 2.

[0078] In the embodiment of the present application, the flexible portion 412 can be deformed by adjusting the relative position of the rigid portion 411 and the head-mounted component 2, thereby facilitating the adjustment of the volume of the sound cavity 416 and achieving the adjustment of the sound signal of the speaker 4.

[0079] Specifically, in the embodiment of the present application, the flexible portion 412 may be a flexible structure with elastic characteristics, which may be elastically deformed, and the rigid portion 411 may drive the flexible portion 412 to stretch or contract. The rigid portion 411 may be slidably matched with the head-mounted component 2 or movably matched in other ways. The rigid portion 411 may be movably connected to the rigid section 21 of the head-mounted component 2, and the rigid portion 411 may be movable along the extension direction of the rigid section 21. The movement of the rigid portion 411 may drive the expansion and contraction deformation of the flexible portion 412, and the sound-emitting unit 42 may be freely regulated along the extension direction of the rigid section 21.

[0080] Specifically, in the embodiment of the present application, the flexible portion 412 can also be fixedly connected to the device body 1 to achieve an indirect connection with the head-mounted component 2. The flexible portion 412 is arranged at one end of the rigid portion 411 close to the device body 1, and the flexible portion 412 can also be filled with a line to facilitate the placement of a wiring harness connecting the sound unit 42 and the device body 1.

[0081] Optionally, the shell 41 has a buckling portion 413, which is buckled and connected to the head-mounted component 2, and the position of the buckling portion 413 relative to the head-mounted component 2 is adjustable.

[0082] In the embodiment of the present application, the relative position of the buckle portion 413 and the head-mounted component 2 can be adjusted, thereby adjusting the position of the shell 41, so that the near-ear distance between the speaker 4 and the human ear can be adjusted.

[0083] Optionally, the buckling portion 413 is a hole for penetrating the head-mounted component 2, so as to facilitate adjustment of the relative position between the buckling portion 413 and the head-mounted component 2.

[0084] In the embodiment of the present application, the position of the speaker 4 can be adjusted by adjusting the relative position of the speaker 4 and the head-mounted component 2. In this way, the user can adjust the distance of the speaker 4 close to the ear according to his or her own feelings to meet the needs of different users for the sound signal of the speaker 4.

[0085] Specifically, due to the differences in head circumferences between different users, for users with small head circumferences and users with large head circumferences, the user can adjust the ear distance of the speaker 4 from the human ear by adjusting the relative position of the housing 41 and the head-mounted component 2, which can provide users with freedom of choice. Among them, the smaller the ear distance between the speaker 4 and the human ear, the clearer the user can hear the audio.

[0086] In some other optional embodiments of the present application, the head display device also includes an adjustment mechanism 5, the shell 41 includes a accommodating portion 414 and an earmuff portion 415 connected to each other, the accommodating portion 414 and the earmuff portion 415 enclose a sound cavity 416, the accommodating portion 414 is provided with a second sound outlet hole 4141 communicating with the sound cavity 416, and the earmuff portion 415 is provided with a third sound outlet hole 4151 communicating with the sound cavity 416; the adjustment mechanism 5 is movably cooperated with the second sound outlet hole 4141 for adjusting the second sound outlet hole 4141; the accommodating portion 414 is rotatably connected to the head-mounted component 2 so that the shell 41 can switch between a first state and a second state, in the first state, the head-mounted component 2 blocks the third sound outlet hole 4151; in the second state, the head-mounted component 2 opens the third sound outlet hole 4151.

[0087] In the embodiment of the present application, the adjusting mechanism 5 can adjust the opening size of the second sound hole 4141. By adjusting the state of the shell 41, the third sound hole 4151 can also be opened and closed. In this way, at least one of the second sound hole 4141 and the third sound hole 4151 can be adjusted to emit sound, which can meet the user's demand for the diversity of sound signals of the speaker 4.

[0088] Specifically, in the embodiment of the present application, the earmuff portion 415 is worn on the ear of the user to play audio into the ear, and the privacy of the user can also be improved.

[0089] For example, Fig. 9 As shown, when the adjustment mechanism 5 opens the second sound hole 4141, the shell 41 can be adjusted to the first state, so that the head-mounted component 2 blocks the third sound hole 4151, so that the speaker 4 can play audio through the outer ear. The third sound hole 4151 is blocked, which can reduce the leakage of sound from the third sound hole 4151 and improve the reliability of the sound output from the second sound hole 4141.

[0090] like Fig.10As shown, when the adjustment mechanism 5 closes the second sound outlet 4141, the shell 41 can be adjusted to the second state, the earmuff part 415 can be separated from the head-mounted part 2, and the earmuff part 415 can be rotated to be close to the user's ear to achieve privacy of playback.

[0091] Specifically, the movement of the adjustment mechanism 5 and the movement of the accommodating portion 414 may be controlled independently or synchronously, and this embodiment of the present application does not specifically limit this.

[0092] Specifically, the adjustment mechanism 5 can adjust the second sound hole 4141 to be open or closed, and can also adjust the second sound hole 4141 to any state between open and closed, that is, the second sound hole 4141 can be fully opened or partially opened.
