Description

Technical Field

[0001] This invention relates to the field of virtual reality device technology, and more particularly to a virtual reality device. Background Technology

[0002] When we hear sounds, we can distinguish sounds coming from different directions. This is because the auricle modulates the sound, allowing the brain to determine the direction of the sound. Two important principles include the binaural effect and the auricle effect. Due to the position of the ears and the obstruction of parts of the head, there is a time difference and an intensity difference when sound reaches the ears, which helps the brain determine the horizontal position of the sound source—this is the binaural effect. Due to the complex structure of the auricle, sound undergoes refraction, reflection, and diffraction before entering the ear canal, resulting in differences in intensity and frequency of sound from different directions, which helps the brain identify the vertical position of the sound source.

[0003] However, when we use headphones, the way sound is received is different from natural sound reception. The sound from in-ear headphones is directly "poured" into the ear canal without being modulated by the outer ear, so the human brain still perceives it differently from natural sound. Over-ear headphones, on the other hand, provide some enclosure for the ears, and the sound emitted from the speakers is modulated slightly by the auricle, making the brain perceive it as more like natural sound with a certain sense of three-dimensional space, but it still differs from natural sound to some extent.

[0004] In related technologies, virtual reality devices often use traditional headphones without processing the sound, so the sound entering the ears cannot provide users with a natural auditory experience.

[0005] Head Related Transfer Functions (HRTFs) describe the head's phase and frequency response as sound travels towards us, and are a sound localization algorithm. They include the effects of time and intensity differences in determining sound location, as well as the spectral effects used to determine sound location. This algorithm simulates the various modulation effects of sound waves from emission, reflection, and through the head (nose, auricle, mouth, forehead, and bones, etc.) and ears, simulating how the human nervous system determines the location of a sound source, especially its vertical height. HRTFs are analogous to the brain's working mode, using signal processing methods to simulate the sound signals reaching both ears to reconstruct a complex spatial sound field, allowing users to hear more natural stereo sound.

[0006] However, the HRTF models established in related technologies are not individualized. Because everyone's ear shape, head shape, and even the left and right ears differ physiologically, while using a standard HRTF library can largely simulate natural sound, it still differs from the natural sound each person actually hears. Therefore, personalized HRTF models need to be built for each individual's ear shape.

[0007] Therefore, a new virtual reality device is needed to solve the aforementioned technical problems. Summary of the Invention

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] refer to Figure 1 and Figure 2This embodiment provides a virtual reality device, including: a glasses unit 100 for displaying a virtual reality scene; a wearable unit 200, physically connected to at least two opposite sides of the glasses unit 100 in the direction connecting the user's eyes, for wearing on the user's head to fix the glasses unit 100 in front of the user's eyes; an auricle image acquisition unit 300, physically connected to the glasses unit 100 or the wearable unit 200, the auricle image acquisition unit 300 being provided with a structured light source device 301 and an image acquisition device 302, wherein the structured light source device 301 is used to emit structured light to the user's ear, and the image acquisition device 302 is used to acquire an image of the user's ear; and a controller (not shown in the figure), used to determine the user's auricle parameters based on the user's ear image, so as to generate sound transmitted to the user's ear based on the virtual reality scene and the user's auricle parameters.

[0036] In this embodiment, the "glasses" part can refer to the component of the virtual reality device used to display virtual reality images. When a user wears the virtual reality device, the glasses part can be located in front of the user's eyes. The wearable part can be, for example, a structure similar to the temples of eyeglasses, or a structure that wraps around the head (e.g., a strap).

[0037] In this embodiment, the structured light source device and the image acquisition device can be magnetically attached to the auricle image acquisition unit or embedded into it; this application does not specifically limit this. Data transmission between the image acquisition device and the controller can be wired or wireless; this application does not specifically limit this either. When data transmission is wired, the auricle image acquisition unit can be configured with a hollow structure for wiring. By emitting structured light into the user's ear, the acquired ear image contains the user's ear depth information. Structured light projects a one-dimensional or two-dimensional image onto the object being measured, and determines the surface shape of the object based on the image deformation.

[0038] Using the virtual reality device of this embodiment, structured light can be used to illuminate the user's ear to acquire an image of the user's ear. Then, based on the image, the user's auricular parameters are determined. Sound is generated based on the virtual reality image and the user's auricular parameters and transmitted to the user's ear. This sound generation incorporates the modulation effect of the user's auricle on the sound, generating personalized spatial stereo sound. Therefore, the sound transmitted to the user's ear sounds closer to natural sound, providing a better spatial stereo experience and increasing immersion.

[0039] In one embodiment, reference Figure 4The auricle image acquisition unit includes: a first connecting rod 310, with a first connecting part 303 provided at a first end of the first connecting rod 310, the first connecting part 303 being used for at least physical connection with the eyeglasses part 100 or the wearable part 200; a second connecting rod 320, with a second end opposite to the first end being vertically fixedly connected to the first connecting rod 310, and a structured light source device 301 and an image acquisition device 302 provided on the side of the second connecting rod 320 facing the wearable part 200.

[0040] In this embodiment, the first connecting rod and the second connecting rod can be, for example, cylindrical, cuboid, or other suitable shapes. The shapes of the first connecting rod and the second connecting rod can be the same or different; this application does not impose specific limitations on this. When data transmission is performed via a wired method, the first connecting rod and the second connecting rod can be configured as hollow structures.

[0041] The auricular image acquisition unit can be connected to the eyeglasses or wearable device via a magnetic attraction structure, a plug-in interface, or other methods; this application does not specifically limit the connection. For example, when the auricular image acquisition unit is connected to the eyeglasses or wearable device via a magnetic attraction structure, the first connecting part can be a magnetic connector; when the auricular image acquisition unit is connected to the eyeglasses or wearable device via a plug-in interface, the first connecting part can be a plug. When the auricular image acquisition unit is also electrically connected to the eyeglasses or wearable device, data can be transmitted through the conductive parts in contact with each other in the magnetic attraction structure, or data can be transmitted through a physical data plug-in interface.

[0042] In one embodiment, reference Figure 3 The wearable part 200 is provided with a second connecting part 203, which is adapted to the first connecting part 303 to realize at least a physical connection between the auricle image acquisition part 300 and the wearable part 200.

[0043] In this embodiment, at least a physical connection between the auricle image acquisition unit and the wearable unit is achieved through the connection between the first connecting part and the second connecting part, referring to... Figure 1 and Figure 2 A second connection is provided in the wearable part. After the user wears the virtual reality device, the structured light source device can illuminate the user's ear from the front, and the image acquisition device can also acquire an image of the user's ear from the front, thus capturing a relatively clear image. The first and second connection parts can be physical data interfaces, such as a Type-C interface.

[0044] In one embodiment, reference Figure 4The first connecting portion 303 is located on the end face of the first end of the first connecting rod 310; the second connecting portion 203 is located on the side surface of the wearing portion 200 away from the eyeglass portion 100.

[0045] In this embodiment, an opening may be provided on the surface of the wearable part 200 away from the eyeglasses part 100 to accommodate the second connecting part 203, and a flap may be provided at the opening to cover the opening. When the first connecting part 303 and the second connecting part 203 are detached, the flap can cover the opening to protect the second connecting part 203. The flap may be a rubber pad.

[0046] In this embodiment, the first connecting part and the second connecting part can be connected by the shortest possible distance.

[0047] In one embodiment, the eyeglasses 100 is provided with a third connecting portion (not shown in the figure), which is adapted to the first connecting portion 303 to realize at least a physical connection between the auricle image acquisition unit 300 and the eyeglasses 100.

[0048] In this embodiment, the connection between the auricle image acquisition unit and the eyeglasses unit can be realized by connecting the first connecting part and the third connecting part. The auricle image acquisition unit can have a smaller size, and in the case of wired connection, a shorter communication line can be used for connection.

[0049] In one embodiment, the first connecting portion 303 is located on the end face of the first end of the first connecting rod 310; the third connecting portion is located on the side surface of the eyeglasses portion 100 facing the wearing portion 200.

[0050] In this embodiment, the first connecting part and the third connecting part can be connected by the shortest possible distance.

[0051] In one embodiment, reference Figure 5 The wearable part 200 has a fourth connecting part 204 on the side surface away from the eyeglasses part 100; the auricle image acquisition part 300 includes: a flat shell 330, a fifth connecting part 304 on the first side of the flat shell 330, the fifth connecting part 304 and the fourth connecting part 204 cooperate to form a first folding mechanism to realize the flat shell 330 folding along the extension direction of the wearable part 200, and a structured light source device 301 and an image acquisition device 302 are provided on the flat shell 330.

[0052] In this embodiment, the first folding mechanism formed by the cooperation of the fourth connecting part and the fifth connecting part can be of various types, such as a hinge. (See reference) Figure 6The fourth connecting part can be a short cylinder provided on the wearable part, and the fifth connecting part can be a round hole provided on the flat shell. The round hole cooperates with the short cylinder to form the first folding mechanism to realize the folding of the flat shell.

[0053] In this embodiment, the auricle image acquisition unit is connected to the wearable unit via a first folding mechanism. The auricle image acquisition unit is located on the side of the wearable unit away from the glasses. When the user wears the virtual reality device, the image acquisition device in the auricle image acquisition unit can capture an image of the user's ear from a diagonally rear position near the cheek.

[0054] In one embodiment, reference Figure 5 An elastic limiting mechanism 305 is also provided between the first side of the flat shell and the wearable part, the elastic limiting mechanism 305 being used to limit the folding angle of the flat shell.

[0055] In this embodiment, the elastic limiting mechanism can be, for example, a limiting spring or an elastic sheet. For instance, the two ends of the limiting spring are connected to the flat shell and the wearable part, respectively, and the elasticity of the spring limits the angle at which the flat shell opens.

[0056] Limiting the folding angle of the flat shell can make its open state more stable and prevent damage.

[0057] In one embodiment, reference Figure 5 An elastic insertion member 306 is also provided on the second side opposite to the first side of the flat shell 330; an elastic insertion member 206 is also provided on the surface of the wearable part 200 away from the eyeglasses part 100. The elastic insertion member 206 and the elastic insertion member 306 cooperate to form a pop-out mechanism, so that the flat shell 330 can be popped out by pressing.

[0058] In this embodiment, the cooperation of the elastic insertion component and the elastic plug-in component allows the flat shell to fit more securely against the surface of the wearable part when it is not flipped open, preventing the flat shell from shaking.

[0059] In one embodiment, a first groove 207 is formed on the surface of the wearable part 200 away from the eyeglasses part 100, and the first groove 207 is used to accommodate the auricle image acquisition part 300.

[0060] In this embodiment, a first groove is formed on the surface of the wearable part, so that the auricle image acquisition part can protrude less when it is attached to the surface of the wearable part, thereby reducing the impact on the auricle image acquisition part.

[0061] In one embodiment, reference Figure 7The auricle image acquisition unit 300 includes: a third connecting rod 340, the third end of which is movably connected to a surface of the eyeglasses unit 200 parallel to the plane where the user's eyes are located, and a structured light source device and an image acquisition device (located on the side of the third connecting rod 340 facing away from the paper) are provided at the fourth end of the third connecting rod 340 opposite to the third end.

[0062] In this embodiment, by providing a third connecting rod, the auricle image acquisition unit can extend to both sides of the cheek to acquire images of the ear behind the cheek. The third connecting rod is movable, allowing it to rotate or fold around its third end where it connects to the eyeglasses.

[0063] In one embodiment, the third end of the third connecting rod 340 is movably connected to the side of the surface in the direction of the line connecting the user's eyes via a second folding mechanism.

[0064] In this embodiment, the second folding mechanism can be, for example, a hinge 307. The third end of the third connecting rod is movably connected to the side of the surface of the eyeglasses in the direction of the line connecting the user's eyes via the second folding mechanism, thereby enabling the third connecting rod to fold from the surface of the eyeglasses towards both sides of the cheeks to acquire an image of the auricle. In the case of wired data transmission, the third connecting rod can be hollow, and an FPC (Flexible Printed Circuit) 308 can extend from the third end of the hollow third connecting rod and connect to the image acquisition device.

[0065] In one embodiment, a second groove 208 is formed on the surface of the eyeglass portion, the second groove 208 being used to accommodate the third connecting rod.

[0066] In this embodiment, by using the second groove to accommodate the third connecting rod, the protrusion of the third connecting rod from the surface of the eyeglasses can be reduced, thus protecting the third connecting rod from damage.

[0067] Optionally, when using FPC for data transmission, an additional receiving space can be provided for FPC in the second groove 208, so that when the third connecting rod rotates or folds around the connection position between its third end and the eyeglasses, FPC 308 can move in the receiving space to avoid being crushed.

[0068] In one embodiment, the wearable part 200 includes: over-ear headphones;

[0069] The auricular image acquisition unit can be placed on the side of the over-ear headphones where the speaker is located, that is, the auricular image acquisition unit can be placed on the side facing the user's ear.

[0070] Optionally, on the side of the over-ear headphones where the speaker is located, the auricular image acquisition unit can be positioned near the center or near the edge. In cases where the over-ear headphones include a rigid housing portion for housing the speaker and a soft material portion for cushioning contact with the ear, the rigid housing portion and the soft material portion can be connected by adhesive or snap-fit ​​methods. The auricular image acquisition unit can be positioned in the center or at the edge of the rigid housing portion, with corresponding openings in the soft material portion to allow the structured light source to directly illuminate the user's ear and the image acquisition device to directly acquire an image of the user's ear. Additionally, a protective ring can be provided at the edge of the opening in the soft material to prevent damage to the soft material.

[0071] In most cases, there will be a certain distance between the over-ear headphones and the ears, which is usually about 2 centimeters. The FOV (Field of View) and depth of field of the corresponding auricular image acquisition unit can be selected according to the specific distance.

[0072] In one embodiment, there are two or more image acquisition devices.

[0073] In this embodiment, there can be two, three, or more image acquisition devices. By combining structured light with multiple image acquisition devices, ear images from multiple angles can be acquired, resulting in more accurate depth information of the user's ear and thus more accurate auricle parameters.

[0074] In another embodiment, when there are two or more image acquisition devices, the structured light source device can be replaced with an infrared light source device.

[0075] In one embodiment, the controller is further configured to: acquire an image of the user's ear; determine the user's auricle parameters based on the ear image; determine HRTF models for different sound source directions for the user's ear based on the user's auricle parameters; and generate sound transmitted to the user's ear using the HRTF models for the corresponding sound source directions, based on the user's virtual position and virtual sound source direction in the virtual reality scene.

[0076] Among them, HRTF models can be obtained through mathematical modeling. They can be generated by deep learning based on existing standardized HRTF libraries to generate HRTF models for different sound source directions determined by auricular parameters; or they can be obtained by finding the closest HRTF model in the standardized HRTF library based on auricular parameters.

[0077] In this embodiment, the user's auricular parameters can be extracted based on the user's ear image. HRTF models for different sound source directions are determined based on these parameters. Combining the user's virtual position and virtual sound source direction in the virtual reality scene, the sound transmitted to the user's ear is generated using the HRTF model for the corresponding sound source direction.

[0078] In other embodiments, at least a structured light source device can be added to the controller of the virtual reality device, thereby enabling the virtual reality device controller to capture images of the user's ears.

[0079] When using the handle in this embodiment, the user can first rotate the handle near the ear to capture an image of the ear. The data is then transmitted back to the controller via a Bluetooth or Wi-Fi module installed in the handle, where image processing and depth information analysis are performed. This embodiment offers greater control over the shooting range, allowing for clearer and more varied ear images. Furthermore, it reduces costs by adding components to an existing handle structure.

[0080] The virtual reality device of the present invention combines a structured light source device and an image acquisition device, thereby acquiring the user's auricular parameters, generating personalized spatial stereo sound for the user, and enhancing the user's experience.
