[0021] In this example implementation, an augmented reality glasses is first provided. Figure 1 As shown, the augmented reality glasses include: a glasses body 120 and a sound-generating device 130 , wherein the sound-generating device 130 is disposed on the glasses body 120 , and is used to generate sound waves.
[0022] The augmented reality glasses provided in the embodiments of the present disclosure generate sound waves through a sound-generating device 130 disposed on a glasses body 120. The sound waves are transmitted to the hard bone after passing through the skin and subcutaneous soft tissue, and then transmitted to the cochlea to produce bone conduction hearing. This solves the problem in the related art that headphones are not comfortable to wear and need to be plugged into the ear canal, which may damage the user's eardrum after long-term use. This improves the comfort and safety of wearing the augmented reality glasses.
[0023] Furthermore, the augmented reality headset provided in the embodiment of the present disclosure also includes a wearing portion 110, and the glasses body 120 is connected to the wearing portion 110, and the wearing portion 110 is used to fix the glasses body 120 in a wearing position when worn.
[0024] The following is a detailed description of each part of the augmented reality glasses provided by the embodiment of the present disclosure:
[0025] The glasses body 120 may include a bracket, a controller, a camera, a display device, a communication device, etc. The controller, camera, display device and communication device are all installed on the bracket. When the glasses are in a wearing state, the display device is located directly in front of the user's eyes. A plurality of cameras may be provided on the bracket, and the viewing angles of the plurality of cameras may be different. Real images are collected by the plurality of cameras, and the collected real images are sent to the controller. The controller superimposes and fuses the real image and the virtual image to form an augmented reality image, and finally displays the augmented reality image on the display device. The virtual image may be generated by the controller or by an external device, and then transmitted to the controller through the communication device.
[0026] The bracket may include a display frame and a mounting portion located on the side of the display frame, the display device is mounted on the display frame, and the controller, camera, display device, communication device and speaker may be arranged on the mounting portions on both sides of the display frame.
[0027] The display device may be an OLED (Organic Light-Emitting Diode) display device or an LCD (Liquid Crystal Display) display device. The controller is connected to the driving circuit of the display device, and sends the driving signal of the fused real image and virtual image to the driving circuit of the display device to drive the display device to display the augmented reality image. It is understandable that the display device may also be a micro-projection device, etc., and the embodiments of the present disclosure are not limited thereto.
[0028] like Figure 2 As shown, a sound generating installation part 121 is arranged on the top of the eyeglass body 120, and a sound generating device 130 is arranged on a first side of the sound generating installation part 121, and the first side is the side close to the wearer when wearing. The top of the eyeglass body 120 refers to the side of the eyeglass body 120 close to the top of the wearer's head when wearing.
[0029] The sound-generating device 130 and the eyeglass body 120 are detachably connected. For example, two sides of the sound-generating mounting portion 121 are provided with slide grooves, and the sides of the sound-generating device 130 are provided with sliders, which can move along the slide grooves and be stuck in the preset positions of the slide grooves. Of course, in actual applications, the sound-generating device 130 and the eyeglass body 120 can also be connected by other means, such as threaded connection, etc., and the embodiments of the present disclosure are not limited thereto.
[0030] The power signal of the sound-generating device 130 may be provided by the glasses body 120 , so a power interface may be provided on the glasses body 120 , and a power plug may be provided on the sound-generating device 130 , and the power plug may be connected to the power interface.
[0031] The detachable connection between the sound device 130 and the glasses body 120 enables the augmented reality glasses provided by the embodiments of the present disclosure to be applicable to a variety of scenarios. In a usage scenario where sound is required, the sound device 130 is connected to the glasses body 120, and in a usage scenario where sound is not required, the sound device 130 can be disassembled to reduce the weight of the augmented reality glasses.
[0032] like Figure 3 As shown, the sound-generating device 130 may include a vibration component 131 and an adjustment component 132. The vibration component 131 is used to vibrate to generate sound waves; the adjustment component 132 is respectively connected to the eyeglass body 120 and the vibration component 131, and the adjustment component 132 is used to make the vibration component 131 contact the wearer's forehead when wearing the glasses.
[0033] Among them, the vibration component 131 may include a bone conduction speaker, which is used to generate sound waves. The sound waves are transmitted through the frontal bone, bony labyrinth, inner ear lymph, spiral organ, auditory nerve, and finally transmitted to the auditory center, so that the user can feel the sound. One end of the adjustment component 132 is connected to the eyeglass body 120, and the other end of the adjustment component 132 is connected to the vibration component 131. The adjustment component 132 is used to adjust the posture of the vibration component 131 so that the vibration component 131 can be close to the user's forehead, so that the sound waves are transmitted to the user's frontal bone.
[0034] like Figure 4 As shown, the vibration component 131 may include one or more vibration mechanisms 1311, and each vibration mechanism 1311 is connected to the glasses body 120 through the adjustment component 132. When the augmented reality glasses are worn, due to the differences in the contours of the foreheads of different users, the vibration component 131 may not be able to fit closely to the user's forehead, thereby affecting the conduction of sound waves. Therefore, the vibration component 131 may include a plurality of vibration mechanisms 1311, and the plurality of vibration mechanisms 1311 are independent of each other. The adjustment component 132 provides a force to each vibration mechanism 1311, respectively, so that each vibration mechanism 1311 fits closely to the user's forehead. The plurality of vibration mechanisms 1311 may be arranged linearly or in an array.
[0035] Furthermore, the vibration assembly 131 may also include a bracket, and a plurality of mounting holes are provided on the bracket. The plurality of mounting holes may be arranged linearly or in an array, and the vibration mechanism 1311 is mounted on the mounting holes. The extension direction of the mounting holes may be parallel to the movement direction of the vibration mechanism 1311, and the mounting holes may be used to constrain the movement of the vibration mechanism 1311 to prevent the vibration mechanism 1311 from deviating from a preset trajectory when moving.
[0036] On this basis, the adjustment component 132 may include one or more elastic members 1321, one end of each elastic member 1321 is connected to a vibration mechanism 1311, and the other end of the elastic member 1321 is connected to the glasses body 120. When the augmented reality glasses are in the wearing state, the user's forehead contacts the vibration mechanism 1311, the vibration mechanism 1311 compresses the elastic member 1321, and the elastic force of the elastic member 1321 acts on the vibration mechanism 1311, so that the vibration mechanism 1311 is close to the user's forehead. For example, the elastic member 1321 may be a spring.
[0037] Of course, the adjustment component 132 can also be other structures. For example, the adjustment component 132 can include: an image acquisition device, a control device and a drive device. The image acquisition device is arranged on the side of the eyeglass body 120 facing the wearer, and is used to acquire the forehead image of the wearer and transmit the forehead image of the wearer to the control device. The control device processes the forehead image of the wearer, calculates the three-dimensional coordinates of the wearer's forehead, and sends a drive signal to the drive device according to the three-dimensional coordinates of the wearer's forehead. The drive device is connected to the vibration mechanism 1311, and the drive device drives each vibration mechanism 1311 to move according to the three-dimensional coordinates of the wearer's forehead, so that the vibration mechanism 1311 and the wearer's forehead can match.
[0038] The image acquisition device may include multiple cameras, and the multiple cameras respectively acquire images of the user's forehead. For example, the image acquisition device may include two cameras, and the two cameras are respectively arranged on both sides of the glasses body 120 to respectively acquire images of the wearer's forehead from two perspectives. Of course, in actual use, the image acquisition device may also include three cameras or four cameras, etc., and the embodiments of the present disclosure are not limited thereto.
[0039] When the camera captures an image of the wearer's forehead, the image is sent to the control device. The control device calculates the three-dimensional coordinates of multiple positions on the wearer's forehead through a multi-eye vision algorithm. When calculating the three-dimensional coordinates of multiple positions on the wearer's forehead, the control device can select the three-dimensional coordinates of the points corresponding to the positions of the vibration mechanism 1311 when the wearer is worn. Among them, for one vibration mechanism 1311, one or more corresponding points can be selected to calculate the three-dimensional coordinates.
[0040] The driving device may include a plurality of linear motors, each of which is connected to a vibration mechanism 1311. The control device sends a driving signal to the plurality of linear motors according to the three-dimensional coordinates of the points corresponding to the vibration mechanism 1311. The linear motor receives the driving signal and outputs power to drive the vibration mechanism 1311 to move to the corresponding position according to the driving signal. When the control device outputs the control signal, the three-dimensional coordinates of the wearer's forehead can be converted into the three-dimensional coordinates of the augmented reality glasses by coordinate conversion, and the vibration mechanism 1311 can be driven to the corresponding coordinate point position in the augmented reality glasses by the linear motor. So that the surface of one side of the plurality of vibration mechanisms 1311 close to the wearer forms a contact surface that matches the shape of the wearer's forehead.
[0041] A contact block is disposed at one end of the vibration mechanism 1311 away from the glasses body 120, and a plurality of contact blocks form a contact surface, which contacts the forehead of the wearer when the augmented reality glasses are worn. The contact block can be made of soft materials such as resin or rubber to increase the comfort of the user when using the glasses.
[0042] The contact block protrudes inward from the inner surface of the eyeglass body 120. In order to make the contact surface of the contact block close to the wearer's forehead when worn, the size of the headband formed by the wearing portion 110 is adjustable. For example, the wearing portion 110 includes: a first eyeglass leg 111 and a second eyeglass leg 112, the first end of the first eyeglass leg 111 is connected to one side of the eyeglass body 120; the first end of the second eyeglass leg 112 is connected to the other side of the eyeglass body 120, the second end of the first eyeglass leg 111 is connected to the second end of the second eyeglass leg 112, and the connection position of the first eyeglass leg 111 and the second eyeglass leg 112 is adjustable. Of course, in actual applications, the headband formed by the wearing portion 110 may also include an elastic band, and the elastic force of the elastic band provides pressure to the adjustment block so that the adjustment block is close to the wearer's forehead.
[0043] When the vibration assembly 131 includes a plurality of vibration mechanisms 1311, such as Figure 5 As shown, the augmented reality glasses provided by the embodiment of the present disclosure may further include a control circuit 140 , and the control circuit 140 is respectively connected to the multiple vibration mechanisms 1311 for sending sound signals to the multiple vibration mechanisms 1311 .
[0044] The control circuit 140 can send a sound signal to multiple vibration mechanisms 1311 at the same time, or send a sound signal to any one or more of the multiple vibration mechanisms 1311. Different from the air conduction pathway, the medium for transmitting sound / vibration in the bone conduction pathway is solid or a solid-liquid mixture, and the characteristics of the transmission path have a significant impact on the sound quality of bone conduction. The skin and subcutaneous soft tissue have greater mechanical damping, and their transmission efficiency for high-frequency sound / vibration is low, which makes the high frequency of bone conduction sound weak or missing; the hard bone on the transmission path has greater rigidity, and its transmission efficiency for low-frequency sound / vibration is low, which makes the low frequency of bone conduction sound weak or missing. Therefore, the control circuit can control the provision of a sound signal to the vibration mechanism 1311 according to the frequency of the sound to be transmitted. For example, when the sound frequency is within the first preset range, part of the vibration mechanism 1311 receives the sound signal; when the sound frequency is outside the first preset range, all the vibration mechanisms 1311 receive the sound signal.
[0045] The control circuit 140 may include a signal generator 141 and a switch circuit 142. The signal generator 141 is used to generate a sound signal. The input end of the switch circuit 142 is connected to the signal generator, and the output end of the switch circuit 142 is connected to the vibration mechanism 1311 respectively.
[0046] The switch circuit 142 may include a plurality of switch units, a first end of each switch unit is connected to a signal generator, and a second end of the switch unit is correspondingly connected to a vibration mechanism 1311. The switch unit may be a transistor, an electromagnetic switch, or a trigger switch.
[0047] For example, when the switch unit is a transistor, the first end of the transistor is connected to the signal generator, the second end of the transistor is connected to the vibration mechanism 1311, and the control end of the transistor is connected to the control signal. The control signal is generated according to the frequency of the sound to be transmitted, and the on-off state of each transistor is controlled by the control signal. The control end of each transistor can be a gate, the first end can be a source, and the second end can be a drain; or, the control end of each transistor can be a gate, the first end can be a drain, and the second end can be a source. In addition, each transistor can also be an enhancement transistor or a depletion transistor, which is not specifically limited in this example embodiment.
[0048] The vibration mechanism 1311 may include a bone conduction speaker, which may be at least one of an electromagnetic speaker, a piezoelectric speaker, and an electrostatic speaker. Specifically, the electromagnetic speaker may be a dynamic speaker or a moving iron speaker.
[0049] The electromagnetic speaker has a structure with compound vibration. The voice coil is placed in the magnetic gap formed by the magnetic circuit, the voice coil is connected to the bracket, the bracket is connected to the magnetic circuit through the first elastic element; the bracket is also connected to the shell through the second elastic element; the vibration plate is connected to the bracket to transmit the vibration from the bracket; the vibration plate is connected to the contact block, the contact block contacts the wearer's forehead, and the vibration generated by the bone conduction speaker is transmitted to the wearer's forehead through the vibration plate and the contact block.
[0050] The augmented reality glasses provided in the embodiments of the present disclosure generate sound waves through a sound-generating device 130 disposed on a glasses body 120. The sound waves are transmitted to the hard bone after passing through the skin and subcutaneous soft tissue, and then transmitted to the cochlea to produce bone conduction hearing. This solves the problem in the related art that headphones are not comfortable to wear and need to be plugged into the ear canal, which may damage the user's eardrum after long-term use. This improves the comfort and safety of wearing augmented reality glasses.
[0051] Those skilled in the art will readily appreciate other embodiments of the present disclosure after considering the specification and practicing the application disclosed herein. The present application is intended to cover any modification, use or adaptation of the present disclosure, which follows the general principles of the present disclosure and includes common knowledge or customary techniques in the art that are not disclosed in the present disclosure.
