Description

Technical Field

[0001] The present invention relates to the technical field of image display, and in particular to a prompting device. Background Art

[0002] The teleprompter, as the name implies, is used to prompt the lines. It consists of a beam splitter at a certain angle placed between the speaker and the camera, and a display placed between the speaker and the beam splitter. The beam splitter is a special coated optical glass that can refract and reflect light at the same time. The display content is imaged on the beam splitter through reflection, and the speaker can be photographed by the camera through the refraction of the beam splitter. In this way, the person being filmed can face the camera while reading the lines, which can well solve the problem of forgetting words or making mistakes in words, making recording and live broadcasting easier and more natural.

[0022] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The teleprompter in the related art is usually only applicable to one shooting device, either a camera or a mobile phone, and cannot take into account multiple shooting devices. In addition, the teleprompter in the related art has a unique shooting angle for the shooting device, that is, the shooting device can only shoot horizontally, which cannot meet the user's shooting needs for different themes and environments.

[0025] For this reason, please see Figures 1 to 16 The present invention provides a prompting device 100, which is suitable for a shooting device 200, which includes but is not limited to a mobile phone, a camera, etc. In order to meet the shooting needs of users, the shooting device 200 has a horizontal shooting position and a vertical shooting position. Figure 1 and Fig.16 The prompting device 100 includes a support assembly 110, a display 120 and a beam splitter assembly 130. The support assembly 110 has a display side 111 and a shooting side 112 that are arranged opposite to each other, and the shooting side 112 is suitable for installing the shooting device 200. The display 120 is connected to the support assembly 110 and is located on the display side 111, and is used to display the content of the manuscript. The beam splitter assembly 130 is connected to the support assembly 110 and is used to project the content of the manuscript displayed on the display 120. When the shooting device 200 is located in the horizontal shooting position, the display 120 and the beam splitter assembly 130 are located outside the shooting field of view 210 of the shooting device 200; similarly, when the shooting device 200 is located in the vertical shooting position, the display 120 and the beam splitter assembly 130 are also located outside the shooting field of view 210 of the shooting device 200. Such a design enables the prompting device 100 to be applicable to different shooting scenes and different shooting themes, and improves the applicable scope of the prompting device 100 while allowing the speaker to read the prompting without interfering with the camera, thereby improving the shooting efficiency and quality. It is understood that in some embodiments, in order to adapt to different shooting heights and angles, the bracket assembly 110 can be designed as a structure with adjustable height and tilt angle.

[0026] In order to further improve the user experience and shooting quality of the teleprompter device 100, and optimize the manufacturing process of the teleprompter device 100, please refer to Fig.16In some embodiments, the beam splitter assembly 130 includes a lens 131, and the plane where the lens 131 is located intersects with the plane where the display 120 is located and forms an angle θ. It should be noted that the plane where the display 120 is located may be a plane parallel to the horizontal plane, and the plane where the lens 131 is located is tilted relative to the horizontal plane. For ease of description, the lens 131 is defined to have a first end 1311 and a second end 1312, the first end 1311 is close to the display 120, the second end 1312 is far away from the display 120, the distance from the first end 1311 to the plane where the display 120 is located is a, and the distance from the first end 1311 to the second end 1312 is c. It can be understood that the first end 1311 may be the lowest end of the lens 131, and the second end 1312 may be the highest end of the lens 131. The bracket assembly 110 includes a first bracket 113 for mounting the beam splitter assembly 130 and a second bracket 114 for mounting the display 120, and the first bracket 113 and the second bracket 114 may be vertically arranged. The display 120 has a display area 121 (the display area 121 may be a display screen on the display 120 that is actually used to display the document content), the distance from one end of the display area 121 close to the first bracket 113 to the first bracket 113 is m, and the distance from one end of the display 120 close to the first bracket 113 to one end away from the first bracket 113 is b (i.e., the size of the display 120 in the direction from the shooting side 112 to the display side 111), wherein,

[0027] and,

[0028] Among them, a>0, b>0, c>0, m≥0.

[0029] Exemplarily, under the premise of satisfying the above relationship, the effect of preventing the display 120 and the beam splitter assembly 130 from entering the shooting field of view 210 can be achieved by increasing the angle θ between the lens 131 and the horizontal plane, shortening the width of the display 120 or shortening the length b of the second bracket 114, reducing the distance m from the end of the display area 121 close to the first bracket 113 to the first bracket 113, and increasing the distance a from the first end 1311 of the lens 131 to the plane where the display 120 is located. It should be noted that the parameters such as the width of the display 120 or the length b of the second bracket 114, the distance m from the end of the display area 121 close to the first bracket 113 to the first bracket 113, and the distance a from the first end 1311 of the lens 131 to the plane where the display 120 is located can be adjusted according to the specific volume of the display 120 (including but not limited to a display screen, a tablet computer, a mobile phone, etc.) and the prompting device 100 actually used, so that the display 120 and the beam splitter assembly 130 are located outside the shooting field of view 210. In some embodiments, the display 120 and / or the beam splitter assembly 130 may be further prevented from entering the shooting field of view 210 by reducing the thickness of the lens 131. Exemplarily, the ratio of the transmittance to the reflectance of the lens 131 may be 7:3.

[0030] It is understandable that in some embodiments, in order to ensure the efficiency and accuracy of the prompting device 100, the relative position and angle of the beam splitter assembly 130 and the display 120 are crucial. Through the above-mentioned geometric relationship, such as the angle θ, the distances a, c, m and b, the projection path of the manuscript content can be accurately controlled to ensure that the manuscript content is accurately transmitted to the photographer. At the same time, the problem of the display 120 and / or the beam splitter assembly 130 entering the shooting field of view 210 is avoided. It should be noted that the selection of the angle θ can be set according to the optical characteristics of the beam splitter assembly 130 and the shooting field of view 210 of the shooting device to ensure that the manuscript content can be clearly seen at different shooting positions and to ensure that the beam splitter assembly 130 does not enter the shooting field of view 210. At the same time, the specific values ​​of the distances a and c between the display 120 and the beam splitter assembly 130 can be set on the premise of ensuring that the propagation path of the light in the beam splitter assembly 130 is the shortest, reducing light loss, and improving the clarity of the image. In addition, the specific values ​​of the distance m and b between the display 120 and the first bracket 113 can be set according to the visible range of the display 120, so that it can adapt to the contents of documents of different sizes and avoid entering the shooting field of view 210, thereby improving the applicability of the prompting device 100.

[0031] In some embodiments, the plane where the lens 131 is located intersects with the plane where the display 120 is located and forms an angle θ, and the angle θ satisfies 45°≤θ≤55°. Exemplarily, the angle θ can be 45°, 48°, 50°, 52°, 54°, 55°, etc. When the angle θ is within this range, the beam splitter assembly 130 can effectively reflect the document content on the display 120 to the operator's line of sight in front of the shooting device 200, while ensuring that the operator does not directly see the display 120, thereby avoiding interference of the reflected light on the operator. It can also avoid the problem that the display 120 and / or the beam splitter assembly 130 enters the shooting field of view 210 and affects the shooting quality and shooting efficiency. It should be noted that the angle θ can be applied to different shooting devices, different shooting angles and different displays 120 by combining parameters such as the width of the display 120 or the length b of the second bracket 114, the distance m from the end of the display area 121 close to the first bracket 113 to the first bracket 113, and the distance a from the first end 1311 of the lens 131 to the plane where the display 120 is located, which greatly improves the applicability of the prompting device 100. This not only improves the reading comfort of the operator, but also allows the operator to read the manuscript content smoothly without looking at the display 120, thereby improving the professionalism and efficiency of the shooting process and ensuring that the shooting quality is not affected.

[0032] It should be noted that when the shooting device 200 adopts a horizontal shooting position, the shooting field of view 210 has a larger field of view in the horizontal direction and a smaller field of view in the vertical direction, so the angle θ can be taken as a value close to 45°. In some embodiments, the value of the angle θ can also be taken as a value close to 55°, so the beam splitter assembly 130 can be made outside the shooting field of view 210 by adjusting the length c of the lens 131, the width of the display 120 or the length b of the second bracket 114, the distance m from one end of the display area 121 close to the first bracket 113 to the first bracket 113, and the distance a from the first end 1311 of the lens 131 to the plane where the display 120 is located. When the shooting device 200 adopts a vertical shooting position, the shooting field of view 210 has a smaller field of view in the horizontal direction and a larger field of view in the vertical direction, so the beam splitter assembly 130 can be prevented from entering the shooting field of view 210 by increasing the value of the angle θ (the tilt angle of the lens 131), that is, the angle θ can be taken as a value close to 55°. In other embodiments, the value of the angle θ may also be close to 45°, so that the beam splitting mirror assembly 130 may be outside the shooting field of view 210 by adjusting parameters such as the length c of the lens 131, the width of the display 120 or the length b of the second bracket 114, the distance m from the end of the display area 121 close to the first bracket 113 to the first bracket 113, and the distance a from the first end 1311 of the lens 131 to the plane where the display 120 is located.

[0033] It is understandable that, in some embodiments, the selection of the angle θ between the lens 131 and the display 120 can be based not only on optical principles, but also on the needs of actual application scenarios. For example, in an outdoor shooting environment, in order to reduce the impact of direct sunlight on the beam splitter assembly 130, the value of the angle θ can be appropriately increased to be close to 55°, so as to better utilize natural light, while reducing the intensity of reflected light and improving the operator's reading experience. In addition, for different types of shooting devices 200, such as camera lenses with different focal lengths, the value of the angle θ between the lens 131 and the display 120 can be adjusted to ensure the best visual effect. In some embodiments, the angle θ between the lens 131 and the display 120 can be set to be dynamically adjustable, and the size of the angle θ can be changed by a motor or a manual knob to adapt to different shooting environments and needs, thereby improving the flexibility of the device and enhancing the user experience.

[0034] See also Figure 2 and Fig.12 In some embodiments, the beam splitter assembly 130 includes a lens 131 and a protective shell 132. The lens 131 is mounted on the side of the protective shell 132 facing the display 120, and the protective shell 132 is rotatably connected to the bracket assembly 110. The end of the protective shell 132 close to the bracket assembly 110 is provided with a first connecting protrusion 1321, and the end of the first bracket 113 close to the protective shell 132 is provided with a second connecting protrusion 1131, and the second connecting protrusion 1131 and the first connecting protrusion 1321 are alternately arranged and rotatably connected to each other. This design allows the beam splitter assembly 130 to rotate freely at different angles, so that the position of the beam splitter assembly 130 can be adjusted according to the needs of the operator (that is, the angle of the lens 131 relative to the display 120 can be adjusted), ensuring the best projection effect of the manuscript content while preventing the display 120 and / or the beam splitter assembly 130 from entering the shooting field of view 210. In addition, the rotatable design also facilitates the storage and transportation of the prompting device 100, and improves the portability of the prompting device 100. In this way, the prompting device 100 can be flexibly used in various shooting environments to meet the usage requirements in different scenarios.

[0035] It is understood that, in some embodiments, the rotatable connection between the protective shell 132 and the bracket assembly 110 can not only adjust the angle of the beam splitter assembly 130 to meet different shooting requirements, but also protect the beam splitter assembly 130 to improve the durability of the prompting device 100. In some embodiments, the protective shell 132 can be designed as a multi-layer structure, with the inner layer being a lightweight material and the outer layer being a wear-resistant material to reduce the overall weight of the device and improve the impact resistance. In addition, the connection between the first connecting protrusion 1321 and the second connecting protrusion 1131 can be achieved in a variety of ways. For example, a spherical joint connection can be used to achieve a larger rotation range and higher flexibility. In some embodiments, the connection part can also be provided with a damping mechanism to prevent the beam splitter assembly 130 from rotating at will without the action of an external force, thereby maintaining the stability of the prompting device 100. In addition, in order to further improve the portability of the device, the protective shell 132 can be designed to be foldable, and the beam splitter assembly 130 can be folded by simple operation to reduce the occupied space of the device. This design not only facilitates the carrying of the device, but also helps to protect the beam splitter assembly 130 from damage.

[0036] See also Figure 2 and Figure 5 In some embodiments, the support assembly 110 of the prompting device 100 further includes an adjusting member 140, which is disposed at one end of the first connecting protrusion 1321 away from the second connecting protrusion 1131, or the adjusting member 140 is disposed at one end of the second connecting protrusion 1131 away from the first connecting protrusion 1321. The adjusting member 140 is configured to control and lock the rotation angle of the protective shell 132 relative to the support assembly 110. Thus, the user can easily adjust the angle of the beam splitter assembly 130 through the adjusting member 140 to adapt to different shooting requirements while preventing the beam splitter assembly 130 or the display 120 from entering the shooting field of view 210. The design of the adjusting member 140 not only provides a flexible adjustment function, but also ensures that the beam splitter assembly 130 can be stably maintained at the desired angle after adjustment, avoiding angle changes caused by external vibration or improper operation. This design improves the reliability of the device and user experience.

[0037] It is understood that in some embodiments, the adjustment member 140 can be a knob with a scale, and the user can accurately adjust the angle of the spectroscope assembly 130 by rotating the knob, and fix it in the desired position through the locking mechanism of the knob. The scale design of the knob can provide intuitive visual feedback to help the user quickly find the best angle. In addition, the adjustment member 140 can also be an electric adjustment mechanism, which drives the rotation of the spectroscope assembly 130 through a motor and realizes precise control of the angle through an electronic control system. This electric adjustment mechanism is not only easy to operate, but also can be automatically adjusted to a commonly used angle through a preset program, further enhancing the user's experience.

[0038] In other embodiments, the adjustment member 140 may be a locking device with a plurality of snap-in positions. When the user adjusts the spectroscope assembly 130 to the desired angle, the locking device may be snapped into the corresponding snap-in position by manual operation to fix the spectroscope assembly 130. This design is simple and reliable, and is suitable for use in scenarios where frequent angle adjustment is required. In order to improve the user's operational convenience, the locking device may be designed to be locked and unlocked with one button, and the user only needs to lightly press to complete the angle adjustment and fixation. In addition, the number and distribution of snap-in positions of the locking device may be adjusted according to actual needs to meet the requirements of different application scenarios.

[0039] See also Figure 5In some embodiments, the adjusting member 140 is disposed at one end of the first connecting protrusion 1321 away from the second connecting protrusion 1131, a mounting groove 13211 is disposed at one side of the first connecting protrusion 1321 away from the second connecting protrusion 1131, a first mounting hole 13212 is disposed at the bottom of the mounting groove 13211, and a second mounting hole 1132 communicating with the first mounting hole 13212 is disposed at the second connecting protrusion 1131. The adjusting member 140 includes a button 141, an elastic member 142, and a plunger 143, the button 141 is movably inserted into the mounting groove 13211, the elastic member 142 is located between the button 141 and the first connecting protrusion 1321 or the second connecting protrusion 1131, the plunger 143 is movably inserted into the first mounting hole 13212 and the second mounting hole 1132, and the plunger 143 is detachably abutted against the button 141. The plunger 143 is configured to be elastic in the direction from the first connection protrusion 1321 to the second connection protrusion 1131, and the button 141 is configured to drive the plunger 143 to move in the direction of penetrating into the second mounting hole 1132 until the plunger 143 is separated from the first mounting hole 13212, so that the protective shell 132 can rotate relative to the first bracket 113. The elastic member 142 is configured to drive the button 141 to move in the direction of exiting the mounting groove 13211, and the button 141 is also configured to be able to rotate in the mounting groove 13211, so that the first mounting hole 13212 is aligned with or deviates from the second mounting hole 1132. When the first mounting hole 13212 deviates from the second mounting hole 1132, the end of the plunger 143 close to the first connecting protrusion 1321 is blocked by the bottom wall of the mounting groove 13211 and remains in the state of being located in the second mounting hole 1132. When the first mounting hole 13212 is aligned with the second mounting hole 1132, the plunger 143 partially extends into the first mounting hole 13212 under the action of elastic force, thereby locking the relative position of the first connecting protrusion 1321 and the second connecting protrusion 1131, thereby preventing the protective shell 132 from rotating relative to the first bracket 113. It should be noted that the elasticity of the plunger 143 can be provided by a spring or by its own elasticity. This design allows the user to lock and unlock the spectroscope assembly 130 by simply operating the button 141, which is easy to operate and has high reliability. In this way, the prompting device 100 can quickly adapt to different shooting requirements, improving the flexibility of the device and user experience.

[0040] It should be noted that the lens 131 can be rotated relative to the protective shell 132 to adjust the tilt angle of the lens 131 relative to the display 120, or the lens 131 is fixed to the protective shell 132, so that the tilt angle of the lens 131 relative to the display 120 can be achieved by rotating the protective shell 132 relative to the first bracket 113.

[0041] It is understood that, in some embodiments, the button 141 and the plunger 143 of the adjustment member 140 can be matched in a variety of ways to achieve their functions. For example, the button 141 can be designed to have multiple gears, each gear corresponding to a fixed angle of the beam splitter assembly 130. The user can select the desired gear by pressing and rotating the button 141, thereby achieving rapid positioning of the beam splitter assembly 130. This multi-gear design not only simplifies the user's operating steps, but also provides more angle options to meet the needs of different shooting scenes. In addition, the surface of the button 141 can be designed to have an anti-slip texture to increase friction and prevent the user from slipping during operation.

[0042] In other embodiments, the adjusting member 140 may adopt a magnetic locking mechanism. The plunger 143 may be designed as a metal member with magnetism, and the inner walls of the first mounting hole 13212 and the second mounting hole 1132 may be set as magnetic materials. When the plunger 143 is inserted into the first mounting hole 13212, the magnetic force will firmly fix it in the first mounting hole 13212, thereby locking the spectroscope assembly 130. When the user needs to adjust the angle, he only needs to press the button 141 to overcome the magnetic force, and the plunger 143 can be completely pushed from the first mounting hole 13212 into the second mounting hole 1132 to unlock the spectroscope assembly 130. This magnetic locking mechanism is not only easy to operate, but also has high stability and reliability. In order to further improve the user's operating experience, the cooperation of the button 141 and the plunger 143 can be designed to have obvious tactile feedback, and the user can judge whether the spectroscope assembly 130 is successfully locked or unlocked by hand.

[0043] In addition, the adjustment member 140 can also be designed to have a memory function. For example, the built-in microprocessor and sensor can record the angles of the spectroscope assembly 130 commonly used by the user, and automatically adjust to these angles the next time it is used. This memory function not only improves the user's operating efficiency, but also reduces the trouble of repeated adjustments, and is particularly suitable for situations where frequent switching of shooting scenes is required. In some embodiments, the microprocessor can also adjust the distance a from the lowest end of the lens 131 to the plane where the display 120 is located according to the type of shooting device and the shooting position of the shooting device, adjust the inclination angle of the lens 131 relative to the display 120, etc., so as to prevent the display 120 and the spectroscope assembly 130 from entering the shooting field of view 210.

[0044] See also Figure 2 , Figure 7 and Fig.12In some embodiments, the protective shell 132 has a shooting surface 1322 on the side facing away from the lens 131, and the prompting device 100 further includes a first stopper 150, which is detachably connected to the shooting surface 1322, and is suitable for aligning the first shooting device 200. The first stopper 150 can be hinged to the protective shell 132, and the first stopper 150 can be rotated to put it in a use state or an idle state. The setting of the first stopper 150 can block light from the first shooting device 200, preventing the lens of the first shooting device 200 from being affected by the light from the shooting side 112, thereby improving the shooting quality. In addition, the first stopper 150 can ensure that the lens of the shooting device 200 is aligned with the shooting surface 1322, thereby ensuring the accuracy and stability of the shooting picture.

[0045] In some embodiments, the prompting device 100 further includes a second stopper 160, which is detachably connected to the shooting surface 1322, and the second stopper 160 is suitable for aligning the second shooting device 200. The second stopper 160 can block light from the second shooting device 200, so as to prevent the light from the shooting side 112 from interfering with the lighting of the second shooting device 200, so as to improve the shooting quality. It should be noted that the first shooting device 200 can be a camera, and the second shooting device 200 can be a mobile phone. The design of the first stopper 150 and the second stopper 160 not only improves the compatibility of the prompting device 100, but also enhances the installation accuracy of the shooting device 200, making the shooting process smoother and more professional.

[0046] In some embodiments, the first stopper 150 and the second stopper 160 can be designed as a structure with a magnetic adsorption function. For example, a magnet can be provided at the bottom of the first stopper 150, and iron sheets or other magnetic materials can be provided at the corresponding positions of the shooting surface 1322 and the first bracket 113. When the first stopper 150 is close to the shooting surface 1322, the magnet will firmly adsorb it on the shooting surface 1322, thereby achieving quick installation and disassembly. This magnetic adsorption design is not only easy to operate, but also has high stability and reliability. In order to further improve the user's operating experience, the surface of the first stopper 150 can be designed with an anti-slip texture to increase friction and prevent the first stopper 150 from slipping relative to the first bracket 113 during operation.

[0047] In addition, the first stopper 150 (and / or the second stopper 160) can also be designed to have a variety of alignment functions. For example, the first stopper 150 can be equipped with a plurality of alignment holes or alignment pins of different shapes and sizes. The user can select a suitable alignment method according to the specific model and interface type of the shooting device 200 to improve the compatibility of the prompting device 100, and provide users with more choices to meet different shooting needs.

[0048] See also Figure 1 , Figure 2 , Fig.14 and Fig.15 In some embodiments, the bracket assembly 110 of the prompting device 100 further includes a third bracket 115, which is detachably connected to the side of the first bracket 113 facing away from the display 120, and the third bracket 115 is configured to be able to install the first shooting device 200.

This design allows the user to flexibly adjust the position of the first shooting device 200 through the sliding member 1151 to adapt to different shooting requirements. The design of the sliding member 1151 not only improves the flexibility of the device, but also ensures the stability and accuracy of the shooting device 200, making the shooting process smoother and more professional.

[0049] It is understood that in some embodiments, the sliding member 1151 can be designed as a slide rail with a ball bearing, and the user can easily adjust the position of the first shooting device 200 by pushing the slide rail. The design of the ball bearing can significantly reduce the sliding resistance and improve the smoothness and stability of the sliding member 1151. In addition, the material of the sliding member 1151 can be selected from high-strength stainless steel or aluminum alloy to ensure its durability and reliability during use. In order to further improve the user's operating convenience, the sliding member 1151 can also be designed as a structure with a locking mechanism, and the user can lock the position of the sliding member 1151 through a simple knob or button operation to prevent sliding caused by external vibration during shooting. In order to further improve the user's operating experience, the sliding member 1151 can also be designed as a structure with a fine-tuning knob, and the user can make subtle adjustments through the fine-tuning knob to achieve more precise alignment.

[0050] In some embodiments, the bracket assembly 110 further includes a fourth bracket 116, which is detachably connected to the shooting surface 1322 and the side of the first bracket 113 away from the display 120, wherein the fourth bracket 116 is configured to be able to install the second shooting device 200. It should be noted that when the third bracket 115 is installed on the first bracket 113, the fourth bracket 116 is separated from the first bracket 113. When the fourth bracket 116 is installed on the first bracket 113, the third bracket 115 is separated from the first bracket 113. Thereby avoiding interference. The provision of the third bracket 115 and the fourth bracket 116 enables the prompting device 100 to be applicable to various types of shooting devices 200, thereby improving the applicability of the prompting device 100.

[0051] See also Figure 8 and Fig. 9In some embodiments, a fixing hole 1133 and a plurality of connecting holes 1134 are provided on the side of the first bracket 113 of the prompting device 100 away from the display 120, and a fixing member 1152 and a plurality of connecting posts 1153 are provided on the third bracket 115.

It should be noted that the first adsorption member 1135 includes but is not limited to magnets, Velcro hooks, etc., and the second adsorption member 1161 includes but is not limited to magnets, frosted hair stickers, etc. Exemplarily, when the first adsorption member 1135 is a Velcro hook, the second adsorption member 1161 can be a frosted hair sticker. The adsorption design allows the fourth bracket 116 to be quickly installed and disassembled, while ensuring its stability and reliability during use. The design of the first adsorption member 1135 and the second adsorption member 1161 not only improves the installation accuracy of the equipment, but also provides users with more installation options to meet different shooting needs.
