[0022] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the relevant invention are shown in the accompanying drawings.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] Figure 1 FIG. 1 shows a schematic structural diagram 100 of an embodiment of a vibration device according to the present application. Figure 1 As shown, the vibration device 100 may include a vibration motor, a vibration motor seat 101 , a pressure guide plate 102 , a main frame 103 and an elastic component 104 .

[0025] Here, the main frame 103 is usually attached to the forehead of the user, so the shape of the main frame 103 is usually curved. The main frame 103 usually includes a connection seat, which is usually used to connect with a head-mounted display device. Both ends of the main frame 103 are usually provided with through holes, as shown in icon 1031.

[0026] A head-mounted display device can be an extended reality device, or an all-in-one device. It is a computing terminal in itself and cannot be used without connecting to a host. A head-mounted display device can also be a helmet-mounted display (HMD), or a head-mounted display. It is a 3DVR (Virtual Reality) graphic display and observation device in virtual reality applications. It can be connected to a host alone to receive 3DVR graphic signals from the host. It is used in a head-mounted manner, and with the help of a three-degree-of-freedom spatial tracking locator, VR output effects can be observed. At the same time, the observer can move freely in space, such as walking and rotating freely, with a strong sense of immersion.

[0027] The pressure guide plate 102 generally includes a pressure rod and a pressure plate, which is used to assist the elastic component 104 to move up and down. Here, the pressure guide plate 102 can be a T-shaped pressure guide plate. The elastic component 104 generally refers to a component that has both elastic power transmission or motion function and damping function, such as a sponge.

[0028] exist Figure 1 In the embodiment, since the elastic member 104 is arranged around the pressure rod of the pressure guide plate 102, Figure 1In the embodiment, the pressing rod of the pressure guide plate 102 is blocked by the elastic component 104. The elastic component 104 is usually located between the pressing plate of the pressure guide plate 102 and the main frame 103. As an example, the two ends of the elastic component 104 can be fixedly connected to the pressing plate of the pressure guide plate 102 and the main frame 103, respectively, for example, they can be fixed by glue or laser welding.

[0029] The vibration motor is usually arranged in the vibration motor seat 101, and the vibration motor can be glued to the vibration motor seat 101. The vibration motor seat 101 is fixedly connected to the first surface of the pressure plate of the pressure guide plate 102. The vibration motor seat 101 and the pressure plate of the pressure guide plate 102 can be glued together by double-sided tape.

[0030] The second surface of the pressure plate of the pressure guide plate 102 is usually against the first end of the pressure rod, and the second end of the pressure rod passes through the through hole 1031 and is movably connected to the main frame 103. An active connection refers to a connection that can maintain relative movement after a component is connected. Here, the second end of the pressure rod can maintain relative movement with the main frame 103.

[0031] Here, when the vibration motor vibrates, the elastic component 104 will be squeezed. During the squeezing, the second end of the pressure rod will pass through the through hole 1031. When the elastic component 104 returns to its original state, the second end of the pressure rod may pass through the through hole 1031 or may not pass through the through hole 1031, depending on the length of the pressure rod.

[0032] The vibration motor vibrates in the vibration motor seat 101, driving the pressure guide plate 102 to vibrate up and down. During this process, the energy generated by the vibration of the vibration motor is absorbed by the elastic component 104, and less energy is transmitted to the main frame 103. By using the vibration device of this solution, the user can increase the immersive touch of the head while reducing the jitter of the head-mounted display device screen caused.

[0033] Figure 2 FIG. 2 shows a structural schematic diagram 200 of another embodiment of a vibration device according to the present application. Figure 2 As shown, the vibration isolation device 200 may further include a stopper 105. The stopper 105 may also be called an outer stopper or a fixing block, and is used to prevent the elastic component 104, the pressure guide plate 102, the vibration motor and the vibration motor seat 101 from falling off from the main frame 103.

[0034] Here, the elastic component 104 can be a spring. At this time, the first end of the spring can be against the main frame 103, and the second end can be against the pressure plate of the pressure guide plate 102.

[0035] The second end of the pressure rod of the pressure guide plate 102 can pass through the spring 104 and the through hole 1031 in sequence, and the tip of the second end of the pressure rod can be fixedly connected to the limiting block 105 .

[0036] The vibration motor vibrates in the vibration motor seat 101, and at the same time drives the limit block 105 and the pressure guide plate 102 to vibrate up and down. In this process, the energy generated by the vibration of the vibration motor is absorbed by the spring 104, and less energy is transmitted to the main frame 103. This solution uses the limit block to prevent the elastic component, the pressure guide plate, the vibration motor and the vibration motor seat from falling off the main frame. In addition, the use of the spring as an elastic component enhances the vibration isolation effect.

[0037] In some optional implementations, the insertion hole of the limit block 105 can be a flat hole, so as to prevent the pressure rod of the pressure guide plate 102 from rotating and fix the pressure guide plate 102 and the limit block 105. It should be noted that the pressure rod of the pressure guide plate 102 is usually not a round rod, for example, it can be a D-shaped pressure rod.

[0038] Figure 3 FIG. 3 shows a schematic structural diagram 300 of an embodiment of a main frame of a vibration device according to the present application. Figure 3 As shown, the main frame 103 may include a first sub-frame 1032 and a second sub-frame 1033, and the first sub-frame 1032 and the second sub-frame 1033 may be connected via a connecting column 1034. The first sub-frame 1032 is used to contact human skin, and the second sub-frame 1033 generally includes a connecting seat 1035. The connecting seat 1035 is used to connect the vibration device to the head-mounted display device. The main frame of this structure is divided into an inner layer and an outer layer, and the energy transmitted is filtered again by the connecting column, so that the vibration margin finally transmitted to the head-mounted display device is not enough to affect the picture of the head-mounted display device.

[0039] Figure 4 FIG. 4 is a structural schematic diagram 400 of another embodiment of the main frame of the vibration device according to the present application. Figure 4 As shown, the vibration device is connected to the head mounted display device via a connection base 1035. The connection base 1035 and the head mounted display device can be adhered together by double-sided adhesive.

[0040] In some optional implementations, soft silica gel or rubber is provided on the end of the first subframe 1032 that contacts the human skin. In this way, the position where the vibration device contacts the user can be made softer, thereby improving the user experience.

[0041] In some optional implementations, guide protrusions are provided at both ends of the main frame, such as Figure 3 As shown in the icon 1036 in FIG. The guide protrusion 1036 is usually coaxial with the through hole 1031, and the guide protrusion 1036 is used to guide the vibration direction of the spring 104 to prevent the vibration direction of the spring from being offset.

[0042] In some optional implementations, the end of the vibration motor base 101 that contacts the skin may be provided with soft silicone or rubber. In this way, the position where the vibration isolation device contacts the user can be made softer, thereby improving the user experience.

[0043] Here, the vibration motor and the vibration motor seat 101 can be connected by double-sided tape. The connection through double-sided tape allows the vibration motor to be removed from the vibration motor seat at any time. The material of the vibration device can be photosensitive resin. Photosensitive resin refers to the material used for photocuring rapid prototyping, which is a liquid photocurable resin, or liquid photosensitive resin, mainly composed of a polymer, a photoinitiator, and a diluent. In the past two years, photosensitive resins are being used in the emerging industry of 3D printing, and are favored and valued by the industry because of their excellent properties. Photosensitive resins generally have the characteristics of high gloss, high strength, high temperature resistance, and waterproofness.

[0044] Figure 5 FIG. 5 shows a schematic diagram 500 of a structure of an embodiment of a head mounted display device according to the present application. Figure 5 As shown, the head mounted display device 500 may include a head mounted display device body 501 and a vibration device 502 described in an embodiment of the present application. The head mounted display device body 501 is connected to the connection base 1035 of the vibration device 502. For example, the head mounted display device body 501 and the connection base 1035 of the vibration device 502 may be glued together.

[0045] By adding a vibration device to the head-mounted display device, the vibration motor vibrates in the vibration motor seat, driving the pressure guide plate to vibrate up and down. In this process, the energy generated by the vibration of the vibration motor is absorbed by the elastic component, and less energy is transmitted to the main frame. The main frame filters the transmitted energy again through the connecting column, so that the vibration margin finally transmitted to the head-mounted display device is not enough to affect the image of the head-mounted display device. The head-mounted display device using this solution can increase the immersive touch of the head while reducing the jitter of the head-mounted display device image.

[0046] Here, the head mounted display device body 501 and the connection base 1035 of the vibration device 502 can be connected by double-sided adhesive tape. The connection by double-sided adhesive tape allows the vibration device to be removed from the head mounted display device body at any time.

[0047] In some optional implementations, the head-mounted display device body 501 can control the vibration motor of the vibration device 502 to vibrate, and after layers of vibration isolation and vibration buffering of the vibration device 502, the vibration margin finally transmitted to the head-mounted display device is not sufficient to affect the picture of the head-mounted display device. The user increases the immersive touch of the head while reducing the jitter of the head-mounted display device picture.

[0048] It should be noted that the head-mounted display device body can output a vibration signal according to the picture situation of the display device, so that the vibration signal changes with the picture situation, providing the user with a dual visual and tactile experience.

[0049] Figure 6 A schematic diagram 600 of an embodiment of an application scenario of a head mounted display device according to the present application is shown. Figure 6 As shown, the user wears a head-mounted display device including a vibration device, and can feel a tactile experience on the head while watching the image of the head-mounted display device. Due to the use of the vibration device, the user can feel the vibration of the head while reducing the jitter of the image of the head-mounted display device.
