Voice acquisition devices are typically mounted on monitor stands or bezels. These stands or bezels have mounting areas for the panel and voice acquisition devices. In existing technology, the distance between the panel mounting area and the voice acquisition device mounting area on the stand is relatively large. This results in a significant deviation between the user's listening position and the front of the display panel during daily use. To improve the listening experience, the user needs to adjust the stand position and rotate the stand or bezel to the voice acquisition device mounting area, which is inconvenient for users and leads to poor overall sound reception.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] With the technological advancements in LCD panels and the increasing demands on monitors, users now require monitors to have voice acquisition capabilities. Voice acquisition devices are typically mounted on monitor stands or bezels. These stands or bezels have mounting areas for the panel and voice acquisition devices. In existing technology, the distance between the panel mounting area and the voice acquisition device mounting area on the stand is relatively large. This results in a significant deviation between the user's listening position and the front of the display panel during daily use. To improve the listening experience, the user needs to adjust the stand position and rotate the stand or bezel to the voice acquisition device mounting area, which is inconvenient for users and leads to poor overall sound reception.

[0041] Especially with the technological advancements in LCD TVs, four-sided bezel-less products are gradually becoming a trend. Meanwhile, voice recognition is an indispensable function for display devices such as TVs. For three-sided bezel-less displays, the voice recognition microphone is typically installed inside the frame on the side of the display panel closest to the ground (ground side). However, for four-sided bezel-less displays where the front is entirely composed of LCD glass, the microphone cannot be mounted on the display surface due to the lack of a ground side frame; it can only be mounted on the non-display side, resulting in poor microphone pickup.

[0042] In order to solve the technical problems of poor sound reception and inconvenience of use of existing borderless displays, the main purpose of this application is to provide a display device and a voice acquisition and control method for the display device that can improve the sound reception of the display panel and make it more convenient to use.

[0043] According to one aspect of this application, a display device is provided, including a panel 10, a frame 20, and a voice acquisition device 30. The panel 10 includes a non-display area 11, which includes a first surface and a second surface disposed opposite to each other. The non-display area 11 has a through hole 111 penetrating the panel 10. The frame 20 faces the second surface and is stacked with the panel 10. A limiting groove 21 is provided facing the through hole 111, and the limiting groove 21 communicates with the through hole 111. The voice acquisition device 30 includes a signal acquisition part 31 and a mounting part 32. The signal acquisition part 31 faces the through hole 111, and the mounting part 32 is detachably fixed in the limiting groove 21 through the through hole 111.

[0044] In one embodiment, reference Figure 1 and Figure 2 As shown, panel 10, frame 20, and back panel 50 are stacked sequentially. Frame 20 is assembled and fixed to panel 10 via connecting layer 40, which can be a foam layer. Panel 10 includes a first side and a second side. Frame 20 faces the second side. The opening of through hole 111 is set on the first side, which better suits user habits and improves the sound reception effect of the display panel on the display surface. Frame 20 is provided with a limiting groove 21 facing through hole 111, which communicates with through hole 111. Voice acquisition device 30 can be set as a microphone. Voice acquisition device 30 includes a signal acquisition unit 31 and a mounting unit 32. Signal acquisition unit 31 can be used to collect and process external sounds. Mounting unit 32 is detachably set behind limiting groove 21 via through hole 111, which allows for easy adjustment of the assembly state of voice acquisition device 30 and display panel, improving the convenience of later maintenance. When it is necessary to replace different types of voice acquisition devices 30, it can be flexibly adjusted through mounting unit 32, improving the applicability of display panel.

[0045] In one embodiment, the through hole penetrates the panel 10, that is, one opening of the through hole 111 is located on the first side of the non-display area 11, and the other opening of the through hole is located on the second side of the non-display area 11. The limiting groove 21 is located on the frame 20. The mounting part 32 can be directly set in the limiting groove 21 before the frame 20 and the panel 10 are assembled. Alternatively, the voice collector 30 can be installed after the frame 20 and the panel 10 are installed. The mounting part 32 is set in the limiting groove 21 after passing through the through hole 111.

[0046] refer to Figures 3-6 As shown, according to one embodiment of this application, it further includes a connecting layer 40, which is disposed between the panel 10 and the frame 20. The connecting layer 40 has a fixing groove, which corresponds to the limiting groove 21 and the through hole 111. Part of the mounting part 32 is limited and fixed in the fixing groove. The fixing cavity further improves the fixing effect of the mounting part 32 and effectively limits the position of the voice collector 30 relative to the panel 10.

[0047] refer to Figures 3-6 As shown, in another embodiment of this application, the through hole 111 has a certain depth along the direction perpendicular to the surface of the panel 10, and the signal acquisition unit 31 is located inside the through hole 111. Thus, the through hole 111 improves the protection effect of the signal acquisition unit 31 on the one hand, and improves the sound reception effect of the signal acquisition unit 31 through the walls around the through hole 111 on the other hand.

[0048] refer to Figure 9 As shown, as an example, according to one embodiment of this application, the opening diameter of the through hole 111 gradually increases from the end face of the signal acquisition unit 31 to the panel 10. As an example, the signal acquisition unit 31 can be configured as a cylindrical structure, and the through hole 111 includes a limiting cavity (not shown in the figure) and a sound receiving cavity (not shown in the figure). The bottom of the limiting cavity is located near the second surface, and the top of the sound receiving cavity is near the first surface. The signal acquisition unit 31 is limited and fixed in the limiting cavity. The signal acquisition unit 31 has a signal acquisition surface facing the sound receiving cavity. From the first surface of the panel 10 to the bottom of the sound receiving cavity, the diameter of the sound receiving cavity gradually decreases. As an example, the sound receiving cavity has a frustum structure, and the limiting cavity is a cylindrical cavity, thereby improving the sound receiving effect of the signal acquisition unit 31 through the sound receiving cavity.

[0049] According to one embodiment of this application, the non-display area 11 includes a slide rail 112 and a baffle 113 slidably mounted on the slide rail 112. The baffle 113 blocks or opens the through hole 111 via the slide rail 112. (See reference) Figures 1-4 As shown, the moving area of ​​the slide rail 112 passes through the through hole 111. The baffle 113 can slide along the extension direction of the slide rail 112. After moving to the through hole 111, it blocks the through hole 111, thereby making the outer surface of the panel 10 flat and preventing damage to the voice collector 30.

[0050] When improved sound reception is required, the baffle 113 can be slid away from the through hole 111, exposing the signal acquisition unit 31 to the outside environment, thereby improving the sound reception effect of the signal receiving unit. The cooperation between the baffle 113 and the slide rail 112 further expands the applicability of the overall display panel and enhances user convenience.

[0051] In another embodiment of this application, the opening of the through hole 111 is located in the non-display area, thereby improving the utilization rate of the overall display area of ​​the display panel.

[0052] According to one embodiment of this application, an electromagnetic control element (not shown in the figure) is included. A baffle 113 is magnetic. The electromagnetic control element generates a magnetic field that attracts or repels the baffle 113, causing the baffle 113 to block or open the through hole 111 along the extending direction of the slide rail 112. The position of the baffle 113 can be adjusted by the electromagnetic control element, and the baffle is driven to slide along the slide rail 112 by the magnetic force between the electromagnetic control element and the baffle 113. When the magnetic force between the electromagnetic control element and the baffle 113 is repulsive, the electromagnetic control element and the baffle 113 move away from each other; when the magnetic force between the electromagnetic control element and the baffle 113 is attractive, the electromagnetic control element and the baffle 113 move closer together, thereby achieving automatic control of the baffle 113 to block or open the through hole 111.

[0053] In one usage scenario, when it is necessary to improve the sound collection effect of the voice collector 30, the electromagnetic control component is set on the side of the slide rail 112 away from the non-display area 11. When the magnetic force between the electromagnetic control component and the baffle 113 is mutually repulsive, the electromagnetic control component and the baffle 113 move away from each other. The baffle 113 moves towards the through hole 111 until it partially or completely blocks the through hole 111. Then, through the mutually repulsive magnetic force, the baffle 113 can be maintained in the position of blocking the through hole 111.

[0054] When the electromagnetic control component and the baffle 113 are attracted by each other, the electromagnetic control component and the baffle 113 move closer to each other. The baffle 113 moves away from the through hole 111, that is, moves closer to the electromagnetic control component, until the through hole 111 is partially or completely exposed. Then the baffle 113 can open the through hole 111, thereby improving the sound reception effect.

[0055] As an example, the electromagnetic control component is electrically connected to the control components of the display panel or monitor to further enhance the intelligence of the display panel and improve ease of use.

[0056] refer to Figure 7 and Figure 8As shown, according to one embodiment of this application, the voice acquisition unit 30 further includes a telescopic component 33, which is mounted on the mounting portion 32. The voice acquisition unit 30 is mounted on the telescopic component 33, and the telescopic component 33 is used to move the signal acquisition unit 31 relative to the through hole 111, so that the signal acquisition unit 31 protrudes from the panel 10 or is housed in the limiting groove 21. Depending on the actual use, the telescopic component 33 can move the signal acquisition unit 31 toward the surface of the panel 10 or to the outside of the panel 10, further reducing the obstruction between the signal acquisition unit 31 and the external sound source and improving the sound reception effect of the signal acquisition unit 31.

[0057] In one embodiment, the telescopic component 33 is electrically connected to the electromagnetic control component. When the baffle 113 opens the through hole 111, the telescopic component 33 controls the signal acquisition unit 31 to move toward the surface of the panel 10 or protrude outward from the outside of the panel 10, thereby improving the convenience of use.

[0058] As an example, the telescopic component 33 can be configured as an electric telescopic rod or a cylinder to drive the signal acquisition unit 31 to reciprocate in a direction perpendicular to the panel 10.

[0059] refer to Figure 5 and Figure 6 As shown, according to one embodiment of this application, the frame 20 includes a limiting wall 22 forming a limiting groove 21. The limiting wall 22 includes a first wall 221 and a second wall 222. The limiting groove 21 includes a first groove 211 with a first opening diameter and a second groove 212 with a second opening diameter. The first wall 221 forms the first groove 211, and the second wall 222 forms the second groove 212. The first opening diameter is smaller than the second opening diameter.

[0060] refer to Figure 7 and Figure 8 As shown, the mounting part 32 includes an elastic component 321 facing the limiting groove 21. The elastic component 321 elastically abuts against the second groove 212 via the first groove 211. After the elastic component 321 elastically abuts against the second groove 212, the displacement of the mounting part 32 relative to the panel 10 in the direction perpendicular to the panel 10 can be limited by the first groove 211 and the second groove 212, effectively preventing the voice collector 30 from accidentally coming out. The elastic component 321 can also limit the horizontal displacement of the voice collector 30 relative to the panel 10 or the limiting groove 21, allowing for precise positioning of the voice collector 30 and preventing the voice collector 30 from coming out of the through hole 111.

[0061] As an example, the first wall 221 and the second wall 222 are arc-shaped walls, and the end of the abutment 3212 is also arc-shaped, which can effectively reduce the friction between the abutment 3212 and the first wall 221 and the second wall 222 during installation or disassembly, and improve assembly efficiency.

[0062] According to one embodiment of this application, the elastic component 321 includes an elastic element 3211 and an abutment element 3212. The abutment element 3212 is assembled to the elastic element 3211 and elastically abuts against the second groove 212 through the elastic element 3211. In one example, the elastic element 3211 can be configured as a spring or a sheet spring. The abutment element 3212 can elastically abut against the limiting wall 22 through the elastic force of the elastic element 3211, thereby achieving the purpose of elastic locking.

[0063] In one embodiment, when the voice acquisition unit 30 needs to be disassembled, the electromagnetic control component can be controlled to open the through hole 111 by controlling the baffle 113. Then, the telescopic component 33 first drives the signal acquisition part 31 to protrude from the outside of the panel 10. Taking the signal acquisition part 31 as the force application point, along the direction perpendicular to the panel 10, when the elastic component 321 is subjected to a large force, it disengages from the limiting groove 21, thereby achieving the purpose of detachably assembling the mounting part 32 into the limiting groove 21.

[0064] In another example, an electromagnetic component can be provided between the abutment 3212 and the limiting wall 22. The magnetic force between the abutment 3212 and the limiting wall 22 can be controlled by the power on and off of the electromagnetic component to make them mutually repulsive or mutually attractive, so as to achieve the purpose of detachably assembling the mounting part 32 into the limiting groove 21.

[0065] In one example, the display panel is a borderless display on all four sides, which has the following advantages:

[0066] ① A through hole 111 corresponding to the position of the frame 20 can be directly provided on the side of the panel 10 near the ground. The signal acquisition part 31 at one end of the microphone is inserted into the through hole 111, and the mounting part 32 at the rear end is inserted into the limiting groove 21 of the frame 20. The installation is simple and has high mass production capability.

[0067] ②The through hole 111 at the front end of the OC (panel 10) (CF&U-POL) is horn-shaped, wherein the wall of the through hole 111 has an angle of 45 to 55° with respect to the perpendicularity of the panel 10. Such a through hole 111 can receive incident sound waves more efficiently.

[0068] ③ The mounting part 32 at the rear of the microphone is provided with an elastic component 321. The elastic component 321 can be set as an elastic rivet post, which is convenient to install and fix with the plastic frame 20, and is easy to install and disassemble.

[0069] ④ The microphone has a telescopic component 33. The telescopic structure of the telescopic component 33 can drive the signal acquisition unit 31 to move relative to the through hole 111. The telescopic component 33 can be set as a cylinder. The cylinder can be controlled by nitrogen gas and atmospheric pressure. The degree of extension and retraction of the telescopic component 33 can be controlled according to the set receiving volume range, so as to more accurately judge the command and control the degree of extension and retraction, so that the signal acquisition unit 31 moves to the ideal position and makes a correct response.

[0070] ⑤ The telescopic component 33 may include an electrically controlled magnetic structure designed at the through hole 111. This electromagnetic control structure can attract the microphone and adjust the magnetic strength according to the power, thereby controlling the telescopic amount of the microphone.

[0071] ⑥ A magnetic baffle 113 is also designed on one side of the through hole 111, which can slide along the slide rail 112. The baffle 113 improves the overall integrity of the screen, and the screen has no openings, which improves the user's comfort when using it and avoids damage to the microphone.

[0072] ⑦ When it is determined that sound needs to be received, a sound reception command is issued. The electromagnetic control component at the through hole 111 controls the baffle 113 to open the through hole 111. When the microphone's received volume is within the normal range, the microphone position remains unchanged; when it is below the normal range, the electrically controlled magnetic structure of the telescopic component 33 is automatically powered on, and the microphone is attracted and moved by the electrically controlled magnetic structure. After the command is completed, the electrically controlled magnetic structure is automatically powered off, the microphone returns to its position, and the baffle 113 blocks the through hole 111, thereby improving the overall automation level of the display panel.

[0073] According to another aspect of this application, a voice acquisition control method for a display device is provided, including a display device, the display device further including a baffle 113;

[0074] When environmental data is acquired, and the environmental data meets preset conditions, the control baffle 113 opens the through hole 111 and the voice collector 30 extends out of the through hole 111. The environmental data includes distance data and volume data between the target user and the display device. The preset conditions include: the distance data is greater than a first preset range; or the volume data is less than a second preset range; or the distance data is greater than the first preset range and the volume data is less than the second preset range.

[0075] Furthermore, under preset conditions, when it is determined that the sound reception effect needs to be improved, if the distance data is greater than the first preset range and the volume data is less than the second preset range, the baffle opens the through hole to receive sound, and the telescopic component drives the signal acquisition unit to move in a direction perpendicular to the panel to achieve better sound reception. When judging the distance, the distance between the user and the display device can be detected in real time by an infrared detection device. When the real-time distance is greater than the first preset range of 3m-5m, the baffle 113 is controlled to open the through hole 111, and the voice acquisition unit 30 extends out of the through hole 111. Alternatively, when judging the volume, a volume detection sensor is used for real-time detection. When the real-time volume is less than the second preset range, where volume represents the strength of the sound, and the second preset range can be set in decibels (dB) according to usage habits, when the volume is detected to be less than the second preset range, the baffle 113 is controlled to open the through hole 111, and the voice acquisition unit 30 extends out of the through hole 111 to achieve better sound reception.
