[0003] Currently, the wearing structure of head-mounted display devices is generally fixed to the main body of the device and has no other functions besides being worn by the user, resulting in the problem of limited functionality of head-mounted display devices. Summary of the Invention

[0011] Optionally, the step of determining the target sound output among the more than one sound output based on the state information includes:

[0012] When the status information indicates that the wearing structure is connected to the main body of the device, the sound output part that meets the preset condition among the more than one sound output part is determined to be the target sound output part, and the preset condition is that the sound output range corresponding to the sound output part is located below the wearing structure.

[0013] When the status information indicates that the wearing structure is separated from the main body of the device, each of the more than one sound-emitting part is determined as a target sound-emitting part.

[0014] Optionally, the more than one sound-emitting part is located at the end of the wearing structure connected to the device body, and the step of controlling the target sound-emitting part to play sound includes:

[0015] The target sound output section is controlled to play sound in the target direction, the angle between the target direction and the horizontal line is a preset angle, the target direction is obliquely downward relative to the horizontal line and the direction of the target direction is away from the connection between the wearing structure and the main body of the device.

[0016] Optionally, when the wearing structure is connected to the main body of the device, it encloses a cavity for wearing on the user's head. Before the step of controlling the target sound-emitting part to play sound in the target direction, the method further includes:

[0017] When the status information indicates that the wearing structure is connected to the main body of the device and the head-mounted display device is in the wearing state, the size characteristic parameters of the cavity are obtained;

[0018] The preset angle is determined based on the size characteristic parameters.

[0019] Optionally, the step of controlling the speaker to play sound based on the status information includes:

[0020] When the status information indicates that the device body is connected to the wearing structure, the device body controls the speaker to play sound.

[0021] When the status information indicates that the device body is separated from the wearing structure, the speaker can be independently controlled to play sound through the wearing structure.

[0022] Furthermore, to achieve the above objectives, this application also proposes a head-mounted display device, the head-mounted display device comprising:

[0023] Equipment body,

[0024] A wearing structure, wherein the wearing structure is detachably connected to the main body of the device, and the wearing structure is provided with a speaker;

[0025] A control device, disposed on the device body and / or the wearing structure, the control device comprising: a memory, a processor, and a control program for the head-mounted display device stored in the memory and executable on the processor, wherein the control program for the head-mounted display device, when executed by the processor, implements the steps of the control method for the head-mounted display device as described in any of the preceding claims.

[0031] When the first conductive element is electrically connected to the second conductive element, the battery module can charge the power module.

[0032] In addition, to achieve the above objectives, this application also proposes a storage medium storing a control program for a head-mounted display device, wherein the control program for the head-mounted display device, when executed by a processor, implements the steps of the control method for the head-mounted display device as described in any of the preceding claims.

[0033] This invention proposes a control method for a head-mounted display device. The device comprises a detachably connected main body and a wearing structure, with a speaker installed within the wearing structure. The method controls the speaker to play sound based on state information indicating whether the wearing structure and the main body are connected. Different state information corresponds to different control parameters for the speaker. Therefore, the wearing structure is not only for user wear but can also control the speaker's sound playback through its installation and removal. The speaker's sound playback can be adjusted differently depending on the connection and separation between the main body and the wearing structure, thereby enriching the functionality of the head-mounted display device and achieving functional diversification.

[0052]

[0053] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0054] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0055] This invention provides a head-mounted display device. The head-mounted display device includes, but is not limited to, augmented reality devices, virtual reality devices, or myopia treatment devices, etc.

[0056] In embodiments of the present invention, such as Figures 1 to 8 As shown, the head-mounted display device includes a main body 1 and a wearing structure 2.

[0057] Wearing structure 2 is detachably connected to device body 1. Wearing structure 2 is equipped with speaker 2a. When wearing structure 2 is connected to device body 1, speaker 2a is in communication with device body 1 and device body 1 controls speaker 2a to operate. When wearing structure 2 is separated from device body 1, speaker 2a is disconnected from device body 1 and speaker 2a can operate independently.

[0058] In this embodiment, the main body 1 of the head-mounted display device and the wearing structure 2 have a connected state and a separated state:

[0059] In the connected state, the wearing structure 2 connects with the device body 1 to form a structure that can be worn on the user's head. The speaker 2a in the wearing structure 2 is communicatively connected to the device body 1. During use, the device body 1 is worn in front of the user's eyes for viewing the displayed content, while the wearing structure 2 surrounds the user's head to prevent the device body 1 from falling off. Simultaneously, the speaker 2a in the wearing structure 2 can be controlled by the device body 1, such as turning the speaker 2a on and off, playing audio, adjusting volume and channels, etc. Therefore, the user only needs to operate from the side of the device body 1 to control both the device body 1 and the speaker 2a, making it easier and faster for the user to access the desired content and improving the user experience. It is understandable that when the device body 1 and the wearing structure 2 are connected, both structural and communicative connections must be ensured. Structurally, the two can be detachably fixed using methods such as snap-fit ​​connections, magnetic connections, or adhesive connections. Regarding communication connections, the two devices can be connected via a wired connection, such as through conductive contact or pin contact, or wirelessly via WiFi or Bluetooth. The specific connection method is not limited here. It should be noted that in this structural configuration, the wearing structure 2 serves both as a strap for the head-mounted display device and as a speaker for the device.

[0060] In the separated state, the wearing structure 2 and the device body 1 are two independent structures. The speaker 2a in the wearing structure 2 is disconnected from the device body 1 and can operate independently, without being controlled by the device body 1. In this state, the wearing structure 2 can be used as a regular speaker device, such as establishing a communication connection with common electronic devices like mobile phones, computers, and televisions, or it can be used independently to play its own built-in audio information. Understandably, in this state, the wearing structure 2 is used as an independent speaker device, and its specific usage depends on its structural shape; for example, it can be used as a neckband speaker or a wristband speaker. It should be noted that when the wearing structure 2 is separated from the device body 1, it can still establish a wireless communication connection with the device body 1 when used as an independent speaker device. In this case, the wearing structure 2 can be used to play audio sounds stored within the device body 1.

[0061] In practical applications, users can select the working state of the head-mounted display device according to their own needs. In this embodiment, the speaker 2a of the wearing structure 2 is modularized. Through the detachable connection between the wearing structure 2 and the main body 1 of the device, a variety of different usage modes of combined use and separate use of the functional modules are realized, which improves the multifunctionality of the head-mounted display device.

[0062] Optionally, the main body 1 of the device has a display module for displaying virtual reality images, augmented reality images, or virtual images, etc.

[0063] Optionally, the wearing structure 2 includes, but is not limited to, a strap, eyeglass temples, or a neckband structure. Specifically, the wearing structure 2 can be a strap structure. When connected to the device body 1, the strap structure is a headband structure and is worn on the user's head. When separated from the device body 1, the strap structure can be hung around the user's neck as a neckband speaker, or the strap structure can be flexibly bent into a wristband form and worn on the user's wrist as a wristband speaker.

[0064] In the head-mounted display device of this invention, the main body 1 and the wearing structure 2 are detachably connected. When the main body 1 and the wearing structure 2 are connected, the speaker 2a in the wearing structure 2 can be controlled by the main body 1, and the main body 1 and the wearing structure 2 can be worn on the user's head. When the wearing structure 2 is separated from the main body 1, the speaker 2a in the wearing structure 2 can operate independently, and the wearing structure 2 can be used as a standalone speaker device. This achieves multiple usage modes for the head-mounted display device, including combined and separate use of the main body 1 and the wearing structure 2, thus improving the versatility of the head-mounted display device.

[0065] In one embodiment of the present invention, reference is made to... Figures 1 to 7 The wearing structure 2 includes a wearable frame 2b for wearing around the user's neck. Both ends of the wearable frame 2b are provided with speakers 2a, and both speakers 2a are detachably connected to the device body 1. When the two speakers 2a are connected to the device body 1, the wearing structure 2 and the device body 1 enclose a cavity for wearing around the user's head.

[0066] This embodiment illustrates the structure of the wearing structure 2. The wearing structure 2 includes a wearable frame 2b for wearing around the user's neck. Speakers 2a are connected to both ends of the wearable frame 2b. Thus, the wearing structure 2 can be used as a neck-mounted speaker device.

[0067] Understandably, the wearing structure 2 and the device body 1 have connected and disconnected states:

[0068] In the connected state, both speakers 2a are connected to the main body 1 of the device. At this time, the main body 1 of the device, the two speakers 2a and the wearable frame 2b are connected and enclosed to form a cavity for wearing on the user's head. At this time, the user can wear the head-mounted display device on his head. The two speakers 2a are controlled by the main body 1 and the wearing structure 2 is used as the head-mounted structure of the head-mounted display device.

[0069] In the separated state, both speakers 2a are separated from the main body 1, and the wearing structure 2 is used as a separate neck-mounted speaker device.

[0070] In practical applications, the wearable frame 2b can be designed with a U-shaped structure to better fit the shape of the human neck. To further improve comfort, a head pad 2c can be added to the wearable frame 2b, which can provide relief to the back of the user's head when used as a headband structure, or to the back of the user's neck when used as a neckband structure.

[0071] In practical applications, the connection structure between the speaker 2a and the wearable frame 2b depends on the actual situation. It can be a snap-on connection, a threaded connection, or a magnetic connection, etc. The specific connection structure is not limited here.

[0072] Furthermore, in one embodiment, referring to Figure 1The speaker 2a includes more than one sound-emitting part 201, with different sound-emitting parts 201 corresponding to different sound emission ranges. In this embodiment, different sound-emitting parts 201 are respectively disposed on the side of the end where the wearing structure 2 is connected to the device body 1, and different sound-emitting parts 201 are disposed on different sides. The wearing structure 2 has multiple sides. The side facing upward when the head-mounted display device is worn on the user's head is defined as the upper side, the side facing downward is defined as the lower side, the side between the upper and lower sides that is away from the user's head is defined as the outer side, and the side between the upper and lower sides that is close to the user's head is defined as the inner side. Thus, the more than one sound-emitting part includes an upper channel disposed on the upper side, a lower channel disposed on the lower side, and an outer channel disposed on the outer side. When both ends of the aforementioned wearing frame 2b are connected to the device body 1, an upper channel, a lower channel, and an outer channel are respectively disposed at both ends. The outer channel located on the left side of the user's head is the left channel, and the outer channel located on the right side of the user's head is the right channel.

[0073] In this embodiment, by setting more than one sound outlet 201, the loudspeaker 2a can emit sound in different directions to meet diverse broadcasting needs and improve the broadcasting effect.

[0074] In one embodiment of the present invention, reference is made to... Figures 1 to 7 The device body 1 is provided with a first conductive element 12, and the speaker 2a is provided with a second conductive element 22. When the speaker 2a is connected to the device body 1, the second conductive element 22 abuts against the first conductive element 12 so that the device body 1 and the speaker 2a can communicate with each other.

[0075] In this embodiment, the speaker 2a and the device body 1 are electrically connected via abutting contact between the first conductive element 12 and the second conductive element 22, thereby achieving a communication connection between them. It is understood that the device body 1 contains a first main control module connected to the first conductive element 12, and the speaker 2a contains a second main control module connected to the second conductive element 22. When the speaker 2a and the device body 1 are installed together, the second conductive element 22 will contact the first conductive element 12 to achieve electrical conduction, thereby enabling the circuit between the first and second main control modules to be connected, thus allowing the device body 1 to control the operation of the speaker 2a. When the speaker 2a is separated from the device body 1, the second main control module inside the speaker 2a can independently control its own operation.

[0076] Optionally, the first conductive element 12 can be a metal conductive sheet, and the second conductive element 22 can be a metal conductive sheet. When the first connector 11 and the second connector 21 are connected, the two metal conductive sheets contact each other to achieve electrical connection.

[0077] In one embodiment of the present invention, reference is made to... Figures 1 to 7The main body 1 of the device includes a power module, which is connected to the first conductive element 12; the wearing structure 2 includes a battery module connected to the speaker 2a, which is connected to the second conductive element 22; when the first conductive element 12 and the second conductive element 22 are electrically connected, the battery module can charge the power module.

[0078] In this embodiment, the power module provides power to the main body 1 of the device, and the battery module provides power to the speaker 2a of the wearing structure 2. By connecting the power module to the first conductive element 12 and the battery module to the second conductive element 22, when the speaker 2a and the main body 1 are installed and used together, the battery module can charge the power module through the electrical connection between the second conductive element 22 and the first conductive element 12.

[0079] Understandably, when the wearing structure 2 is connected to the main body 1, the wearing structure 2 can be used not only as the headband structure of the head-mounted device and as the speaker of the head-mounted device, but also as a charging device to charge the main body 1. When the wearing structure 2 is separated from the main body 1, the battery module inside the wearing structure 2 can independently provide power to the speaker 2a.

[0080] It should be noted that the power module of the main body 1 is connected to the first main control module, and the battery module of the wearing structure 2 is connected to the second main control module. Therefore, when the wearing structure 2 is connected to the main body 1, the battery module can charge the power module through the control of the first and second main control modules.

[0081] Optionally, a charging port can be provided on the wearing structure 2 to charge the battery module and extend its battery life. The charging port can be a Type-C interface.

[0082] In one embodiment of the present invention, reference is made to... Figures 1 to 8 The speaker 2a is slidably connected to the main body 1 of the device.

[0083] Understandably, the sliding connection method between the speaker 2a and the device body 1 can be determined according to the actual situation. For example, it can be in the form of a slide rail or groove, or it can be a sliding form in which the two speakers 2a are fitted and clamped on both sides of the device body 1, etc. In this embodiment, the slidable connection between the two enables the speaker 2a and the device body 1 to be detachably installed, which simplifies the installation structure and improves the user's disassembly and assembly efficiency.

[0084] Specifically, the side wall of the main body 1 of the device is provided with a first connector 11, and the first conductive element 12 is disposed on the first connector 11; the side wall of the speaker 2a is provided with a second connector 21 that slides with the first connector 11, and the second conductive element 22 is disposed on the second connector 21.

[0085] In this embodiment, two speakers 2a are disposed on opposite sides of the device body 1. A first connector 11 is disposed on the side wall of the device body 1, and a second connector 21 is disposed on the side wall of the speakers 2a. The sliding connection between the first connector 11 and the second connector 21 enables the two speakers 2a to slide and connect with the device body 1. Simultaneously, by disposing of a first conductive element 12 on the first connector 11 and a second conductive element 22 on the second connector 21, when the speakers 2a are slidably mounted onto the device body 1, the second conductive element 22 will move to connect with the first conductive element 12. This achieves both a structural connection between the speakers 2a and the device body 1 and a communication connection between them.

[0086] Furthermore, the first connector 11 has a first mating surface that slides with the second connector 21, the second connector 21 has a second mating surface that slides with the first mating surface, the first conductive element 12 is disposed on the first mating surface, and the second conductive element 22 is disposed on the second mating surface.

[0087] This embodiment is based on the sliding connection between the first connector 11 and the second connector 21. By setting the first conductive element 12 and the second conductive element 22 on the sliding mating surface formed by their sliding engagement, sufficient resistance is provided between the first conductive element 12 and the second conductive element 22, resulting in better contact and ensuring the communication strength between the device body 1 and the speaker 2a. Furthermore, setting the first conductive element 12 and the second conductive element 22 on the sliding mating surface ensures contact between the first conductive element 12 and the second conductive element 22 during the sliding process of the first connector 11 and the second connector 21, avoiding poor contact.

[0088] In one embodiment, one of the first connector 11 and the second connector 21 is a guide protrusion 111, and the other is a guide groove 211 that slides with the guide protrusion 111; the first conductive element 12 is disposed on the side wall of the guide protrusion 111 or the guide groove 211, and the second conductive element 22 is disposed on the side wall of the guide groove 211 or the guide protrusion 111.

[0089] In this embodiment, the first connecting member 11 is a guide protrusion 111 or a guide groove 211, and the second connecting member 21 is a guide groove 211 or a guide protrusion 111. The slidable connection between the speaker 2a and the device body 1 is achieved through the sliding engagement of the guide protrusion 111 and the guide groove 211. When the guide protrusion 111 engages with the guide groove 211, the sidewall of the guide protrusion 111 abuts against the sidewall of the guide groove 211. Therefore, the first conductive member 12 can be disposed on the sidewall of the guide protrusion 111 or the guide groove 211, and the second conductive member 22 can be disposed on the sidewall of the guide groove 211 or the guide protrusion 111. This achieves the function of electrical connection when the guide protrusion 111 engages with the guide groove 211, with the first conductive member 12 and the second conductive member 22 abutting against each other.

[0090] Optionally, the first connector 11 is a guide protrusion 111 disposed on the side wall of the device body 1, and the second connector 21 is a guide groove 211 disposed on the side wall of the speaker 2a. The first conductive element 12 is disposed on the side wall surface of the guide protrusion 111, and the second conductive element 22 is disposed on the side wall surface of the guide groove 211. Thus, when the speaker 2a is connected to the device body 1, the guide protrusion 111 is disposed in the guide groove 211, and the side wall surface of the guide protrusion 111 abuts against the side wall surface of the guide groove 211 to ensure the electrical connection strength between the first conductive element 12 and the second conductive element 22.

[0091] Furthermore, the side wall of the device body 1 is provided with a first guide rail 13, and the speaker 2a is provided with a second guide rail 23 that slides with the first guide rail 13. The extension direction of the first guide rail 13 is consistent with the extension direction of the guide protrusion 111. In this embodiment, by setting the first guide rail 13 and the second guide rail 23 to slide with each other, and the extension direction of the first guide rail 13 is consistent with the extension direction of the guide protrusion 111, the sliding movement of the speaker 2a and the device body 1 is guided, making the two more stable and reliable during relative sliding. Optionally, the first guide rail 13 can be provided on both sides of the guide protrusion 111, and correspondingly, the second guide rail 23 can be provided on both sides of the guide groove 211. Through the guiding cooperation of the two first guide rails and the two second guide rails 23, the sliding cooperation reliability of the guide protrusion 111 and the guide groove 211 is further improved, thereby ensuring the contact connection strength between the first conductive element 12 and the second conductive element 22.

[0092] In one embodiment of the present invention, reference is made to... Figures 4 to 11 The first connector 11 is provided with a first limiting member 14, and the second connector 21 is provided with a second limiting member 24. The first limiting member 14 and the second limiting member 24 are mutually limiting and cooperating to provide at least two relatively fixed locking positions between the first connector 11 and the second connector 21.

[0093] In this embodiment, by setting the first limiting member 14 and the second limiting member 24 to limit and cooperate, the first connecting member 11 and the second connecting member 21 have at least two relatively fixed locking positions during the relative sliding process, so that the connection and fixing position between the wearing structure 2 and the device body 1 can be adjusted, thereby realizing the function of adjusting the wearing tightness of the head-mounted display device to suit different head circumferences of different users and improve the user's wearing comfort.

[0094] Specifically, one of the first limiting member 14 and the second limiting member 24 is a plurality of limiting slots 141, and the other is a limiting protrusion 241 that cooperates with the limiting slots 141; the plurality of limiting slots 141 are spaced apart along the sliding direction, and the first connecting member 11 and the second connecting member 21 slide relative to each other, which can drive the limiting protrusion 241 to engage with different limiting slots 141.

[0095] In this embodiment, by setting multiple spaced limiting slots 141 in the sliding direction, when the first connector 11 and the second connector 21 slide relative to each other, the limiting protrusion 241 can be driven to move along the sliding direction to engage with different limiting slots 141, thereby making the first connector 11 and the second connector 21 have different locking positions, so that the user can adjust the tightness of the wearing structure 2 according to their own needs and achieve a comfortable wearing experience.

[0096] Furthermore, the head-mounted display device also includes an adjustment mechanism for adjusting the position of the limiting protrusion 241, so that the limiting protrusion 241 moves between a holding position that engages with the limiting slot 141 and a disengaging position that disengages from the limiting slot 141; the adjustment mechanism includes a pressing member 31 and a transmission assembly 32, the transmission assembly 32 connecting the pressing member 31 and the limiting protrusion 241; the pressing member 31 can drive the transmission assembly 32 to move under external force, so as to move the limiting protrusion 241 from the holding position to the disengaging position.

[0097] In this embodiment, the limiting protrusion 241 can be driven to engage or disengage from the limiting slot 141 by the adjustment mechanism. When it is necessary to adjust the engagement of the limiting protrusion 241 with different limiting slots 141, the user can press the pressing member 31 to drive the transmission component 32 to move, thereby moving the limiting protrusion 241 to disengage from the limiting slot 141. At this time, the first connecting member 11 and the second connecting member 21 are unlocked, and the speaker 2a and the device body 1 can slide relative to each other until they are adjusted to the required wearing tightness. The pressing member 31 is then released so that the limiting protrusion 241 engages with the target limiting slot 141, thereby realizing the movement from one relatively fixed locking position to another relatively fixed locking position. This realizes the adjustment of the size of the wearing cavity of the head-mounted display device and improves the user's wearing comfort.

[0098] Optionally, the transmission assembly 32 includes a transmission rod 321 and a first elastic element 322. The transmission rod 321 is connected to the pressing member 31. The first elastic element 322 includes a connecting arm 322a connected to the transmission rod 321 and elastic arms 322b respectively connected to both ends of the connecting arm 322a. The two elastic arms 322b are respectively connected to one of the limiting protrusions 241, and the limiting protrusions 241 are in the holding position. When the pressing member 31 is pressed, it can drive the transmission rod 321 to press the connecting arm 322a to move, so that the two elastic arms 322b drive the two limiting protrusions 241 to move from the holding position to the disengaged position.

[0099] This embodiment illustrates the structure of the transmission assembly 32. One end of the transmission rod 321 is connected to the pressing member 31, and the other end is connected to the connecting arm 322a of the first elastic member 322. The elastic arms 322b at both ends of the connecting arm 322a are respectively connected to the limiting protrusions 241. Under the action of its own elastic force, the first elastic member 322 causes the limiting protrusions 241 to be held in the limiting groove 141. When the pressing member 31 presses the transmission rod 321 towards the connecting arm 322a, the middle part of the connecting arm 322a is subjected to force, which will drive the elastic arms 322b at both ends to move in the opposite direction, thereby causing the limiting protrusions 241 connected to the two elastic arms 322b to move in the direction away from the limiting groove 141, realizing the disengagement of the limiting protrusions 241 from the limiting groove 141.

[0100] Optionally, the first elastic element 322 is a spring sheet structure, which can adopt a "∪" shaped spring sheet structure.

[0101] Furthermore, the adjustment mechanism also includes a reset component 33, which is used to drive the transmission component 32 to move the limiting protrusion 241 from the disengagement position to the holding position.

[0102] Understandably, when the pressing member 31 is pressed, the limiting protrusion 241 can be disengaged from the limiting slot 141 through the transmission component 32. When the pressing force on the pressing member 31 disappears, the reset component 33 can drive the transmission component 32 to move the limiting protrusion 241 to be engaged with the limiting slot 141.

[0103] Optionally, the reset assembly 33 includes a first reset spring 331 disposed at the end of the transmission rod 321 away from the pressing member 31. When the pressing member 31 is pressed, it pushes the transmission rod 321 to press the connecting arm 322a to move. At this time, the first reset spring 331 is compressed. When the pressing member 31 is released, the first reset spring 331 resets to drive the transmission rod 321 to move toward the pressing member 31. At the same time, it will drive the connecting arm 322a to move toward the direction away from the limiting slot 141, thereby causing the two elastic arms 322b to drive the limiting protrusion 241 to move toward the holding position.

[0104] Furthermore, the reset assembly 33 may also include a second reset spring 332 on the side where the limiting protrusion 241 is away from the limiting slot 141. When the elastic arm 322b drives the limiting protrusion 241 from the holding position to the disengaged position, the second reset spring 332 is compressed. When the pressing member 31 is released, the second reset spring 332 restores its deformation to push the limiting protrusion 241 toward the limiting slot 141 and hold it.

[0105] Optionally, the limiting protrusion 241 can be a beaded structure.

[0106] Understandably, in practical applications, the guide protrusion 111 and the guide groove 211 can be set on the device body 1 or the speaker 2a. The corresponding first limiting member 14 and the second limiting member 24 can also be set on the device body 1 or the speaker 2a. Their specific setting positions can be determined according to the actual situation. In this embodiment, considering factors such as the difficulty of process forming and assembly, the first connecting member 11 of the device body 1 is the guide protrusion 111, the second connecting member 21 of the speaker 2a is the guide groove 211, the limiting slot 141 is set on the guide protrusion 111, and the limiting protrusion 241 is set on the guide groove 211.

[0107] Reference Figures 4 to 11 The guide protrusion 111 has two opposing side surfaces 111a and a limiting surface 111b connecting the two side surfaces 111a. Each side surface 111a is provided with a first conductive element 12, and the limiting surface 111b is provided with a plurality of spaced limiting slots 141. The guide groove 211241 has two opposing groove side surfaces 211a and a groove bottom surface 211b connecting the two groove side surfaces 211a. Each groove side surface 211a is provided with a second conductive element 22, and the groove bottom wall is provided with a limiting protrusion 241. When the guide protrusion 111 slides in the guide groove 211, the side surface 111a abuts against the corresponding groove side surface 211a, so that the first conductive element 12 abuts against the second conductive element 22. The limiting surface 111b cooperates with the groove bottom surface 211b, so that the limiting protrusion 241 is engaged with the limiting slot 141.

[0108] An adjustment mechanism is located on the speaker 2a, and a pressing member 31 is exposed on the outside of the speaker 2a for easy pressing operation by the user. The speaker 2a has a first mounting hole 251 for the movement of the limiting protrusion 241. Two elastic arms 322b are installed through the first mounting hole 251. A second return spring 332 is located inside the first mounting hole 251 and sleeved on the outside of the elastic arms 322b, with its two ends abutting against the bottom wall of the first mounting hole 251 and the limiting protrusion 241, respectively. The speaker 2a has protrusions 26 at the two elastic arms 322a that abut against the elastic arms 322a, serving as fulcrums for the movement of the first elastic member 322, thereby realizing the function of the two elastic arms 322a moving in opposite directions when the connecting arm 322a is pushed to move. The speaker 2a has a second mounting hole 252 at the position corresponding to the transmission rod 321 for mounting a first return spring 331. The first return spring 331 is connected to the bottom wall of the transmission rod 321 and the second mounting hole 252 respectively, thereby realizing the function of resetting the transmission rod 321.

[0109] Furthermore, the head-mounted display device also includes a control device disposed on the device body 1 and / or the wearing structure 2. (See reference...) Figure 12 The control unit for the head-mounted display device includes a processor 1001 (e.g., CPU), a memory 1002, a timer 1003, etc. The components in the control unit are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0110] Those skilled in the art will understand that Figure 12 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0111] In this embodiment, refer to Figure 12 The control device includes a first controller 101 and a second controller. The first controller 101 is located on the device body 1 and is used to control the speaker 2a to play sound when the device body 1 is connected to the wearing structure 2. The second controller 102 is located on the wearing structure 2 and is used to independently control the speaker 2a to play sound when the device body 1 is separated from the wearing structure 2.

[0112] Specifically, when the device body 1 is connected to the wearing structure 2, the second controller 102 responds to the control command of the first controller 101 to control the speaker 2a. The first controller 101 sends the control command of the speaker 2a to the second controller 102, and the second controller 102 controls the speaker 2a to operate according to the command sent by the first controller 101. During this process, the second controller 102 does not operate independently, but operates entirely according to the control command of the first controller 101. Alternatively, when the device body 1 is connected to the wearing structure 2, the first controller 101 directly communicates with the speaker 2a and directly controls the speaker 2a to operate. When the device body 1 is separated from the wearing structure 2, the second controller 102 stops responding to the control command of the first controller 101, and the second controller 102 independently controls the speaker 2a to play sound.

[0113] like Figure 12 As shown, the memory 1002, which serves as a storage medium, may include a control program for a head-mounted display device. Figure 12 In the device shown, the processor 1001 can be used to call the control program of the head-mounted display device stored in the memory 1002 and execute the relevant steps of the control method of the head-mounted display device in the following embodiments.

[0114] This invention also provides a control method for a head-mounted display device, applied to the aforementioned head-mounted display device.

[0115] Reference Figure 13 This application proposes an embodiment of a control method for a head-mounted display device. In this embodiment, the control method for the head-mounted display device includes:

[0116] Step S10: Obtain status information, including whether the wearing structure is connected to the main body of the device;

[0117] In this embodiment, the status information can be determined by monitoring the communication status between the speaker and the device body. When a communication connection is established between the speaker and the device body, the status information is that the wearing structure is connected to the device body; when no communication connection is established between the speaker and the device body, the status information is that the wearing structure is separated from the device body. Specifically, the communication status can be determined by detecting the electrical connection status between the first conductive element and the second conductive element, or by detecting the signal transmission status between the device body and the speaker.

[0118] In other embodiments, the status information can also be determined by obtaining user input instructions. For example, when the speaker is connected to the device body, the user can input a first instruction through a button on the device body; or, when the speaker is disconnected from the device body, the user can input a second instruction through a button on the device body.

[0119] Step S20: Control the speaker to play sound according to the status information.

[0120] Different status information corresponds to different target control parameters for the speaker. The target control parameters are determined based on the status information, and the speaker is controlled to play sound according to the determined target control parameters.

[0121] The target control parameters here may include the first control parameter corresponding to the speaker's sound output direction, the speaker's opening and closing control parameter, the second control parameter corresponding to the speaker's volume, and / or the third control parameter corresponding to the speaker's sound effect playback, etc.

[0122] The correspondence between status information and target control parameters can be a pre-set fixed relationship, or it can be determined by acquiring user-defined parameters and following those parameters. Based on this correspondence, the target control parameters corresponding to the current status information are then determined.

[0123] This invention proposes a control method for a head-mounted display device. The device comprises a detachably connected main body and a wearing structure, with a speaker installed within the wearing structure. The method controls the speaker to play sound based on state information indicating whether the wearing structure and the main body are connected. Different state information corresponds to different control parameters for the speaker. Therefore, the wearing structure is not only for user wear but can also control the speaker's sound playback through its installation and removal. The speaker's sound playback can be adjusted differently depending on the connection and separation between the main body and the wearing structure, thereby enriching the functionality of the head-mounted display device and achieving functional diversification.

[0124] Furthermore, based on the above embodiments, another embodiment of the control method for the head-mounted display device of this application is proposed. In this embodiment, the loudspeaker includes more than one sound-emitting part, and different sound-emitting parts correspond to different sound-emitting ranges, where the different sound-emitting ranges are located in different directions relative to the loudspeaker. (Refer to...) Figure 14 Step S20 includes:

[0125] Step S21: Determine the target sound output among the more than one sound output based on the status information;

[0126] Specifically, one or more of the multiple sound-producing parts can be identified as the target sound-producing part based on the status information.

[0127] Different status information corresponds to different positions and / or numbers of target sound-emitting parts. Based on this, the correspondence between status information and target sound-emitting parts can be pre-established before the head-mounted display device leaves the factory, or the correspondence between status information and target sound-emitting parts can be established according to user setting parameters, and the target sound-emitting part corresponding to the current status information can be determined based on the correspondence.

[0128] Step S22: Control the target sound output part to play sound.

[0129] Here, playing sound from the target output part specifically refers to playing sound solely through the target output part, meaning that while the target output part is playing sound, all other output parts stop playing sound.

[0130] When there is only one target sound output, control the target sound output to play the sound independently; when there is more than one target sound output, control more than one target sound output to play the sound together.

[0131] In this embodiment, since the connection state between the wearing structure and the main body of the device is different, it can indicate that the user has different playback needs for the speaker. Therefore, determining the target sound output part based on the state information is beneficial to ensure that the sound output range of the speaker can be accurately matched with the user's current playback needs, thereby realizing the diversification of functions of the head-mounted display device while improving the user experience.

[0132] Furthermore, in this embodiment, referring to Figure 15 Step S21 includes:

[0133] Step S211: Determine the target sound output part among the more than one sound output parts that meets the preset conditions, wherein the preset conditions are that the sound output range corresponding to the sound output part is located below the wearing structure;

[0134] Step S212: When the status information indicates that the wearing structure is separated from the main body of the device, each of the more than one sound-emitting part is determined as a target sound-emitting part.

[0135] Specifically, when more than one sound output includes the aforementioned upper channel, lower channel, left channel, and right channel, the lower channel is used as the target sound output when the wearing structure is connected to the device body; when the wearing structure is separated from the device body, the upper channel, lower channel, left channel, and right channel can all be used as target sound outputs, resulting in more than one target sound output. Alternatively, when more than one sound output includes the aforementioned upper and lower channels, the lower channel is used as the target sound output when the wearing structure is connected to the device body; when the wearing structure is separated from the device body, both the upper and lower channels can be used as target sound outputs, resulting in more than one target sound output.

[0136] In this embodiment, since the wearing structure of a head-mounted display device is typically worn above the ears, when the wearing structure is connected to the main body of the device, sound is played through a downward-facing sound output. This facilitates the private transmission of the sound required by the main body of the device, improves the sound quality heard by the user, and reduces the power consumption of the speakers. Conversely, when the wearing structure is separated from the main body of the device, it indicates a lower need for privacy in the sound played by the speakers, and the speakers may be farther from the user's ears. In this case, sound is played through all sound outputs, which improves the sound playback effect of the speakers and ensures the volume of the sound heard by the user.

[0137] In other embodiments, when the status information indicates that the wearing structure is separated from the main body of the device, the sound output part that meets the set conditions among the more than one sound output part is determined as the target sound output part. The set conditions are that the sound output range corresponding to the sound output part is located above the wearing structure. Since the wearing structure is set up as a neck-hook speaker after being removed from the main body of the device, the ear is located above the wearing structure. Therefore, using a sound output part with the sound output range facing upwards for sound playback is beneficial to achieve the privacy transmission of the sound required by the main body of the device, while also improving the sound quality that the user can hear and reducing the energy consumption of the speaker required for sound playback.

[0138] Furthermore, in this embodiment, the more than one sound-emitting part is located at the end where the wearing structure connects to the main body of the device, referring to... Figure 15 Step S22 includes:

[0139] The target sound output section is controlled to play sound in the target direction, the angle between the target direction and the horizontal line is a preset angle, the target direction is obliquely downward relative to the horizontal line and the direction of the target direction is away from the connection between the wearing structure and the main body of the device.

[0140] The preset angle is specifically the angle used to direct the sound output direction of the target sound-producing part toward the ear.

[0141] The preset angle is less than or equal to 45 degrees. In this embodiment, the preset angle is 10 degrees. In other embodiments, the preset angle may also be 20 degrees, 30 degrees, or 15 degrees, etc.

[0142] In this embodiment, the preset angle is a pre-set fixed angle. In other embodiments, the preset angle can also be an angle determined by obtaining user adjustment parameters, or an angle determined based on the monitored wearing status of the head-mounted display device.

[0143] like Figure 1 As shown, the target direction is the direction indicated by the arrow in the figure.

[0144] In this embodiment, by means of the above method, when the wearing structure is connected to the main body of the device, the sound played by the target sound output part can be directionally propagated to the user's ear along the target direction, which is conducive to further improving the privacy of the user when using the head-mounted display device.

[0145] In other embodiments, the target sound-emitting part can also be controlled to play sound in different directions within its sound-emitting direction.

[0146] Furthermore, in this embodiment, when the wearing structure is connected to the main body of the device, it forms a cavity for wearing on the user's head. Before the step of controlling the target sound output part to play sound in the target direction, the method further includes: when the state information is that the wearing structure is connected to the main body of the device and the head-mounted display device is in the wearing state, obtaining the size characteristic parameters of the cavity; obtaining the size characteristic parameters of the cavity; and determining the preset angle based on the size characteristic parameters.

[0147] Dimensional characteristics may include perimeter, area, and / or longest inner diameter. These characteristics can be determined by acquiring user-input parameters, monitoring internal pressure parameters, or detecting the installation depth of the wearing structure on the device body.

[0148] Different dimensional feature parameters correspond to different preset angles. Specifically, the dimensional feature parameters can be negatively correlated with the preset angles, meaning that the larger the dimensional feature parameter, the smaller the preset angle.

[0149] Specifically, a correspondence between dimensional feature parameters and preset angles can be established in advance. This correspondence may include mapping relationships or calculation relationships, etc. Based on this correspondence, the preset angle corresponding to the current dimensional feature parameter can be determined. For example, the result of substituting the current dimensional feature parameter into a preset formula can be used as the preset angle. Alternatively, the result obtained by looking up the dimensional feature parameter in a table can be used as the preset angle.

[0150] In this embodiment, the preset angle is determined by the size characteristic parameters of the cavity adapted to fit the user's head. The size characteristic parameters can accurately reflect the size of the user's head circumference. Based on this, the distance between the speaker and the user's ear can be accurately characterized. Therefore, using the size characteristic parameters to determine the preset angle helps to ensure that the sound from the target speaker can be accurately directed toward the user's ear, thereby further improving the privacy of the user when using the head-mounted display device.

[0151] Furthermore, based on any of the above embodiments, another embodiment of the control method for the head-mounted display device of this application is proposed. In this embodiment, reference is made to... Figure 16 Step S20 includes:

[0152] Step S201: When the status information indicates that the device body is connected to the wearing structure, the device body controls the speaker to play sound;

[0153] Specifically, the speaker is controlled to play sound by the first controller in the main body of the device. When the first controller controls the speaker to play sound, it can be implemented according to the scheme related to steps S21 to S22 in the above embodiment, which will not be described in detail here.

[0154] When the status information indicates that the device body is connected to the wearing structure, the first controller can be connected to the second controller or directly to the speaker.

[0155] Step S202: When the status information indicates that the device body is separated from the wearing structure, the speaker is independently controlled to play sound through the wearing structure.

[0156] Specifically, the speaker plays sound independently via a second controller within the wearable structure. The sound played when the main device is separated from the wearable structure can be either internally stored in the wearable structure's memory or received from an external input device when the wearable structure is connected to the main device via wired or wireless means.

[0157] It should be noted that when the main body of the device is separated from the wearing structure, the second controller is prohibited from responding to the control commands of the first controller, and the sound playback of the speaker is independently controlled by the second controller.

[0158] In this embodiment, when the device body and the wearing structure are connected, the speaker in the wearing structure can be controlled by the device body to operate; when the wearing structure is separated from the device body, the speaker in the wearing structure can operate independently, and the wearing structure can be used as a separate speaker device. This achieves multiple usage modes for the head-mounted display device, including combined and separate use of the device body and the wearing structure, thus improving the versatility of the head-mounted display device.

[0159] Furthermore, this embodiment of the invention also proposes a storage medium storing a control program for a head-mounted display device. When the control program for the head-mounted display device is executed by a processor, it implements the relevant steps of any embodiment of the control method for the head-mounted display device described above.

[0160] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.

[0161] The sequence numbers of the above embodiments of the present invention are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments.

[0162] Through the above description of the embodiments, those skilled in the art can clearly understand that the methods of the above embodiments can be implemented by means of software plus necessary general-purpose hardware platforms. Of course, they can also be implemented by hardware, but in many cases the former is a better implementation method.
