Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a display device, a diffusion device, a diffusion equipment, and a terminal. Background Technology

[0002] Embodied intelligence refers to intelligent agents with physical carriers, such as intelligent vehicles and robots. Embodied intelligent terminals can continuously interact with the physical environment through a closed loop of "perception, decision-making, action, and feedback," autonomously learning, adapting, and completing complex physical tasks in an open world.

[0003] In practical applications of embodied intelligent terminals, taking vehicles as an example, with the increasing demand for information display and audio playback in the vehicle cabin, traditional in-vehicle screen displays and audio playback can no longer meet users' visual and auditory experience needs, resulting in a poor intelligent experience for users.

[0004] Therefore, there is an urgent need for a feasible solution to meet users' needs for visual and auditory experiences and improve their intelligent experience. Summary of the Invention

[0005] This application provides a display device, a diffusion device, a diffusion apparatus, and a terminal, which can meet users' visual and auditory experience needs and improve users' intelligent experience.

[0006] In a first aspect, embodiments of this application provide a display device for detachably connecting to a diffusion device used to diffuse sound propagation. The display device includes a display module and a communication module. The display module includes a housing and a display screen, the display screen being connected to the housing, and the display screen and housing forming a receiving cavity, with the communication module disposed within the receiving cavity. The display module is used to display information received through the communication module.

[0007] In this embodiment, the display device is detachably connected to the diffusion device, which facilitates subsequent maintenance and replacement of the display device. The display device and the diffusion device are decoupled from each other and can be evolved separately. If the display device and the diffusion device are integrally formed, then when the display device malfunctions or a new sensor is needed, the entire device, which is integrally formed with the display device and the diffusion device, needs to be disassembled. Therefore, the detachable design between the display device and the diffusion device in this embodiment can greatly reduce the maintenance and modification costs of the display device.

[0008] In one possible implementation, the display device has a built-in communication module, enabling wireless communication. If the display device communicates with the diffusion device via a wiring harness, this harness will occupy video communication interfaces and resources. Since the total number of wired video communication interfaces and resources is limited, this will further reduce the display resolution of other display devices on the terminal where the display device is located (such as vehicle infotainment screens, projection engines, ceiling-mounted screens, etc.), affecting the user's visual experience. Therefore, the wireless communication design of the display device in this embodiment avoids occupying wired video communication interfaces and resources, ensuring the display resolution of the display device and other display devices, and guaranteeing the user's visual experience. Furthermore, if the display device communicates with the diffusion device via a wiring harness, due to space constraints, the harness needs to be an extremely thin coaxial cable with numerous bends, leading to poor reliability and affecting the normal display function of the display device, further impacting the user's visual experience. Therefore, the wireless communication design of the display device in this embodiment avoids the problem of poor harness reliability, ensuring the normal display function of the display device and guaranteeing the user's visual experience. Furthermore, if the display device is connected to the diffusion device via a wiring harness, the display device will be restricted by the wiring harness during rotation, which will limit the rotation angle of the display device and fail to meet the visual experience requirements of users in various positions. Therefore, the wireless communication design of the display device in this embodiment can reduce the impact of the wiring harness restriction, making the rotation angle of the display device more flexible and free, and meeting the visual experience requirements of users in various positions.

[0009] Therefore, the embodiments of this application can satisfy users' auditory experience needs by amplifying sound through a diffusion device, satisfy users' visual experience needs through the detachable design of the display device and the wireless communication design, and satisfy users' visual and auditory experience needs by detachably connecting the display device to the diffusion device, thereby improving users' intelligent experience.

[0010] In one possible implementation, the display device further includes a printed circuit board (PCB). The PCB is disposed within the receiving cavity, and the communication module is disposed on the surface of the PCB.

[0011] In this embodiment, by placing the communication module on the surface of the printed circuit board, no additional brackets or external wiring harnesses are required, resulting in a compact internal structure for the display device. This facilitates miniaturization of the display device and makes it suitable for confined installation environments such as automotive applications. Furthermore, placing the communication module on the surface of the printed circuit board shortens the trace distance between the communication module and other modules, reduces signal loss, and ensures stable communication transmission.

[0012] In one possible implementation, the display device further includes a processing module. The processing module is disposed on the surface of a printed circuit board and is used to process information received via the communication module. The display module is specifically used to display the information processed by the processing module.

[0013] In this embodiment, by placing the processing module on the surface of the printed circuit board, no additional brackets or external wiring harnesses are required, resulting in a compact internal structure for the display device. This facilitates miniaturization of the display device and makes it suitable for confined installation environments such as automotive applications. Furthermore, placing the processing module on the surface of the printed circuit board shortens the trace distance between the processing module and other modules, reduces signal loss, and ensures the timing stability and reliability of the data processing by the processing module.

[0014] In one possible implementation, the display device further includes a power supply. The power supply is disposed within the housing cavity and is used to power the display device.

[0015] In this embodiment, by placing the power supply within the housing cavity of the display device, independent power supply to the display device can be achieved, ensuring its normal display function. Furthermore, the housing cavity provides enclosed protection for the power supply, preventing dust, water, oil, and impacts from foreign objects, thus avoiding external environmental corrosion of the power supply components, extending its lifespan, and ensuring the normal display function of the display device. Optionally, the power supply can be either rechargeable or non-rechargeable.

[0016] In one possible implementation, the display device further includes a power management module. The power management module is disposed on the surface of the printed circuit board and is used to manage the charging and / or discharging of the power supply.

[0017] In this embodiment, by placing the power management module on the surface of the printed circuit board, no additional brackets or external wiring harnesses are required, resulting in a compact internal structure for the display device. This facilitates miniaturization of the display device and makes it suitable for confined installation environments such as automotive applications. Furthermore, placing the power management module on the surface of the printed circuit board allows for shorter power supply traces, lower voltage drop, reduced power loss, and ensures stable power supply performance.

[0018] In one possible implementation, the display device further includes a first charging unit, which is electrically connected to a power management module.

[0019] In this embodiment, the first charging unit in the display device can be a charging interface supporting wired charging, or a wireless charging coil supporting wireless charging. When the power source in the display device is a rechargeable power source, the display device can be detached, and other charging devices (such as third-party chargers) can charge the power source in the display device through the first charging unit.

[0020] In one possible implementation, the diffusion device includes a second charging section, and the first charging section and the second charging section are electrically connected.

[0021] In this embodiment, when the power supply in the display device is a rechargeable power supply, the power supply in the display device can also be charged through a diffusion device. Specifically, the power supply can be continuously charged through a first charging unit and a second charging unit connected together, thereby ensuring the stable power supply performance of the display device.

[0022] In one possible implementation, one end of the first charging unit is connected to the power management module, and the other end of the first charging unit extends out of the receiving cavity, and the other end of the first charging unit is used to contact the second charging unit; and / or, the first charging unit includes a first wireless charging component, which is disposed in the receiving cavity; the second charging unit includes a second wireless charging component, and the first wireless charging component is used to align with the second wireless charging component remotely.

[0023] In this embodiment, the first charging unit and the second charging unit can be electrically connected by contact, or they can be electrically connected by air-to-ground alignment. By using at least one of these electrical connection methods, continuous charging of the power supply can be achieved, ensuring stable power supply performance of the display device.

[0024] In one possible implementation, the display device further includes at least one of the following sensors: a carbon dioxide sensor, a fine particulate matter (PM2.5) sensor, a formaldehyde sensor, a temperature sensor, a humidity sensor, and a light sensor; at least one sensor is disposed on the surface of a printed circuit board.

[0025] In this embodiment, at least one of the aforementioned sensors can be disposed on the surface of the printed circuit board in the display device. These sensors can be integrated into the display device without additional brackets and external wiring harnesses, making the internal space structure of the display device compact and facilitating its miniaturization, thus adapting it to confined installation environments such as automotive applications. Furthermore, disposing of at least one of the aforementioned sensors on the surface of the printed circuit board enables the display device to have functional expansion capabilities, such as carbon dioxide detection, PM2.5 detection, formaldehyde detection, temperature detection, humidity detection, and light detection. Moreover, the detection information can be presented to the user through the display screen of the display device, enhancing the user's intelligent experience.

[0026] In one possible implementation, the display device and the diffusion device are connected by at least one of the following: magnetic connection, snap-fit ​​connection, and threaded connection.

[0027] In this embodiment, the display device and the diffusion device can be detachably connected through at least one of the above connection methods, thereby enabling the display device and the diffusion device to be decoupled from each other and evolve separately, reducing the maintenance and modification costs of the display device.

[0028] In one possible implementation, the housing includes a first magnetic element and the diffusion device includes a second magnetic element; the first magnetic element and the second magnetic element are magnetically connected.

[0029] In this embodiment, the housing includes a first magnetic element. Specifically, the housing itself can be made of a magnetic material, or the magnetic element can be adhered to the surface of the housing facing away from the display screen. By magnetically connecting the first and second magnetic elements, a detachable and fixed connection can be achieved between the display device and the diffusion device. Optionally, the housing may not include the first magnetic element; instead, it can be made of a metal material that can be attracted by the second magnetic element, still achieving a magnetic connection between the housing and the diffusion device. Alternatively, the diffusion device may not include the second magnetic element; instead, it can be made of a metal material that can be attracted by the first magnetic element, again achieving a magnetic connection between the housing and the diffusion device.

[0030] In one possible implementation, the housing includes a first structural member, and the diffusion device includes a second structural member; the first structural member and the second structural member are snap-fitted together or threadedly connected.

[0031] In this embodiment, the first structural component can be a snap-fit, and the second structural component can be a slot; alternatively, the first structural component can be a slot, and the second structural component can be a snap-fit. The snap-fit ​​and slot engage with each other to achieve a detachable and fixed connection between the display device and the diffusion device. Alternatively, the first structural component can be a threaded hole, and the second structural component can be a bolt; alternatively, the first structural component can be a bolt, and the second structural component can be a threaded hole. The bolt and threaded hole are threaded together to achieve a detachable and fixed connection between the display device and the diffusion device.

[0032] Secondly, embodiments of this application provide a diffusion device, which includes: a diffuser and a mounting base. The diffuser is rotatably connected to the mounting base, and the mounting base is rotatably connected to a terminal; the diffuser is used to diffuse the propagation of sound; the diffuser is detachably connected to a display device, and the display device is used to display information.

[0033] In this embodiment, the display device is detachably connected to the diffusion device, which facilitates subsequent maintenance and replacement of the display device. The display device and the diffusion device are decoupled from each other and can be evolved separately. If the display device and the diffusion device are integrally formed, then when the display device malfunctions or a new sensor is needed, the entire device, which is integrally formed with the display device and the diffusion device, needs to be disassembled. Therefore, the detachable design between the display device and the diffusion device in this embodiment can greatly reduce the maintenance and modification costs of the display device.

[0034] Furthermore, the diffuser is rotatably connected to the mounting base, which increases the range of sound propagation and meets the user's auditory experience needs. In addition, the mounting base is used for rotatable connection with the terminal; when the mounting base rotates, it drives the diffuser to rotate as well, thereby further increasing the range of sound propagation and meeting the user's auditory experience needs.

[0035] Therefore, the embodiments of this application can satisfy the user's visual experience needs through the display device, and the rotatable design of the diffuser and mounting base in the diffusion device can increase the propagation range of the diffused sound, thereby satisfying the user's auditory experience needs. By detachably connecting the display device to the diffusion device, the user's visual and auditory experience needs can be satisfied, improving the user's intelligent experience.

[0036] In one possible implementation, the diffuser rotates about a first axis, and the mounting base rotates about a second axis, with the first and second axes not overlapping.

[0037] In this embodiment, by designing the relative positional relationship between the diffuser's rotation axis and the mounting base's rotation axis, the diffuser can rotate at multiple angles, increasing the range of sound propagation and satisfying users' auditory experience needs. Furthermore, the multi-dimensional rotation of the diffuser and the display device increases the viewing area of ​​the displayed content, satisfying the visual experience needs of users in various locations.

[0038] In one possible implementation, the mounting base includes a fixedly connected base and a storage shell; the storage shell has a storage cavity, and a diffuser is disposed inside the storage cavity; the base is used for rotatable connection with the terminal.

[0039] In this embodiment, placing the diffuser inside the housing cavity makes the internal space structure of the diffuser compact, which is beneficial for miniaturization of the diffuser and thus can be adapted to confined installation environments such as vehicle-mounted installations.

[0040] In one possible implementation, when the diffuser is rotated to the first position, the arc-shaped outer peripheral surface of the diffuser and the inner wall surface of the receiving cavity are opposite each other.

[0041] In this embodiment, the arc-shaped outer peripheral surface of the diffuser and the inner wall surface of the receiving cavity are opposite each other, so that when the diffuser rotates, it will not rub against the inner wall surface of the receiving cavity, nor will the gap between the diffuser and the inner wall surface of the receiving cavity be too large. This makes the internal space structure of the diffuser compact, which is conducive to the miniaturization of the diffuser and thus can be adapted to narrow installation environments such as vehicle-mounted installations.

[0042] In one possible implementation, the aforementioned housing shell has an opening that communicates with the housing cavity; when the diffuser is rotated to the second position, the arc-shaped outer peripheral surface of the diffuser is flush with the edge of the opening.

[0043] In this embodiment, the arc-shaped outer peripheral surface of the diffuser is flush with the edge of the opening of the housing shell, which ensures the overall consistency of the appearance of the diffusion device when the diffuser rotates, thus improving the aesthetics of the diffusion device.

[0044] In one possible implementation, the aforementioned housing shell is spherical with a circular opening, and the diffuser further includes a first surface and a second surface, which are connected to opposite sides of the arc-shaped outer peripheral surface, and both the first surface and the second surface are circular.

[0045] In one possible implementation, the display device includes a first charging unit, the diffuser includes a second charging unit, the mounting base includes a third charging unit, the first charging unit and the second charging unit are electrically connected, the second charging unit and the third charging unit are electrically connected, and the third charging unit is electrically connected to a terminal.

[0046] In this embodiment, when the power supply in the display device is a rechargeable power supply, the power supply in the display device can be continuously charged through the electrical connection of the first charging unit and the second charging unit, the electrical connection of the second charging unit and the third charging unit, and the electrical connection of the third charging unit with the terminal, thereby ensuring the stable power supply performance of the display device.

[0047] In one possible implementation, the diffuser and the display device are connected by at least one of the following: magnetic connection, snap-fit ​​connection, and threaded connection.

[0048] In this embodiment, the display device and the diffusion device can be detachably connected through at least one of the above connection methods, thereby enabling the display device and the diffusion device to be decoupled from each other and evolve separately, reducing the maintenance and modification costs of the display device.

[0049] Thirdly, embodiments of this application provide a diffusion device, which includes a display device as described in the first aspect above, and a diffusion device as described in the second aspect above.

[0050] In this embodiment, the rotatable design of the diffuser and mounting base in the diffusion device increases the propagation range of the diffused sound, thereby satisfying the user's auditory experience needs. The detachable design of the display device and the wireless communication design increase the viewing range of the display content, thereby satisfying the user's visual experience needs. By detachably connecting the display device to the diffusion device, the user's visual and auditory experience needs can be satisfied, improving the user's intelligent experience.

[0051] In one possible implementation, the display device is detachably connected to the diffusion device. The diffusion device is used to diffuse the propagation of sound, and the display device is used to display information.

[0052] In this embodiment, the rotatable design of the diffuser and mounting base in the diffusion device increases the propagation range of the diffused sound, thereby satisfying the user's auditory experience needs. The detachable design of the display device and the wireless communication design increase the viewing range of the displayed content, thereby satisfying the user's visual experience needs. By detachably connecting the display device to the diffusion device, the user's visual and auditory experience needs can be satisfied, improving the user's intelligent experience.

[0053] In one possible implementation, the display device includes a first charging unit, the diffusion device includes a second charging unit, and the first charging unit and the second charging unit are electrically connected.

[0054] In this embodiment, when the power supply in the display device is a rechargeable power supply, it can also be electrically connected through the first charging unit and the second charging unit to achieve continuous charging of the power supply and ensure stable power supply performance of the display device.

[0055] In one possible implementation, the diffusion device further includes a third charging unit, the second charging unit and the third charging unit are electrically connected, and the third charging unit is electrically connected to the terminal; the diffusion device is used for rotatable connection with the terminal.

[0056] In this embodiment, when the power supply in the display device is a rechargeable power supply, the power supply in the display device can be continuously charged through the electrical connection of the first charging unit and the second charging unit, the electrical connection of the second charging unit and the third charging unit, and the electrical connection of the third charging unit with the terminal, thereby ensuring the stable power supply performance of the display device.

[0057] In one possible implementation, the above-mentioned diffusion device and display device are connected by at least one of the following: magnetic connection, snap-fit ​​connection, and threaded connection.

[0058] In this embodiment, the display device and the diffusion device can be detachably connected through at least one of the above connection methods, thereby enabling the display device and the diffusion device to be decoupled from each other and evolve separately, reducing the maintenance and modification costs of the display device.

[0063] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described below with reference to the accompanying drawings.

[0069] This application provides a display device, a diffusion device, a diffusion apparatus, and a terminal, relating to the field of terminal technology, such as display devices, diffusion devices, and diffusion apparatuses in vehicle cabins. To more clearly describe the solutions of this application, some terms used in the embodiments of this application will be explained below.

[0070] Embodied intelligence (EI) refers to intelligent systems that possess physical carriers and continuously interact with their physical environment through a closed loop of "perception, decision-making, action, and feedback." These systems autonomously learn, adapt, and complete complex physical tasks in an open world. Examples include intelligent vehicles and robots. Its core lies in the deep integration of perception, understanding, and action, emphasizing the interdependence of the agent's understanding and actions within the physical environment. Embodied intelligence can also be understood as "embodied artificial intelligence," integrating artificial intelligence into physical entities such as robots and vehicles, giving their "brains" a "body," enabling them to perceive, learn, and dynamically interact with their environment like humans.

[0071] Schroeder diffusers are acoustic diffusers that improve the uniformity of the sound field by diffusing and reflecting sound waves through varying groove depths and widths. In car audio systems, the application of Schroeder diffusers allows passengers in every seat to enjoy a similar sound quality experience, expanding the optimal listening area and enhancing auditory consistency.

[0072] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating an application scenario of a diffusion device provided in an embodiment of this application.

[0073] like Figure 1 As shown, taking the vehicle as an example of a smart terminal, with the increasing demand for information display and audio playback in the vehicle cabin, traditional in-vehicle screen display and audio playback can no longer meet the user's visual and auditory experience needs, resulting in a poor user experience of smart technology.

[0074] To enhance the user's intelligent experience in terms of vision and hearing, a diffusion device (such as the Schroeder diffuser mentioned above) is proposed. Optionally, this diffusion device can be installed on the instrument panel (IP) in the vehicle cabin and connected to the cabin's audio system. By setting different groove depths and widths on one surface of the diffuser in the diffusion device, the sound waves emitted by the audio system undergo multiple diffusion and reflections as they pass through the grooves of different depths and widths on the surface. Furthermore, by controlling the rotation of the diffuser in the diffusion device, the angle of the diffuser can be flexibly changed, further expanding the range of sound wave diffusion and reflection. This allows passengers in every seat in the cabin to enjoy a similar sound quality experience, greatly improving the user's intelligent auditory experience.

[0075] Furthermore, a display screen can be installed on another surface of the diffuser in the diffusion device. This display screen can function as an interactive screen, capable of displaying corresponding images, such as vehicle logos or star rings. It's important to note that the display screen of the diffusion device needs to be connected to the controller via a wiring harness. The controller transmits the corresponding video information to the display screen for display through this wiring harness. Moreover, by controlling the rotation of the diffuser in the diffusion device, the angle of the display screen can be flexibly adjusted, further widening the viewing range of the displayed content and significantly enhancing the user's intelligent visual experience.

[0076] However, this diffusion device still has the following drawbacks: (1) The wiring harness between the display screen and the controller of the diffusion device will occupy the video communication interface and video communication resources. Since the total wired video communication interface and wired video communication resources are limited, it will further reduce the display resolution of other display devices in the vehicle cabin (such as the vehicle's in-vehicle screen, projection optical engine, ceiling screen, etc.), affecting the user's visual experience needs.

[0077] (2) Due to the limited installation space in the vehicle scenario, the wiring harness between the display screen and the controller of the diffusion device needs to be an extremely thin coaxial cable. The wiring harness has many bends, which will result in poor reliability of the wiring harness, affect the normal display function of the display screen, and further affect the user's visual experience needs.

[0078] (3) During the process of controlling the diffusion body of the diffusion device to flip, it will be restricted by the wiring harness between the display screen and the controller of the diffusion device, which will further limit the movement angle of the diffusion body, thereby reducing the range of sound wave diffusion and reflection, and making the viewing range of the display content smaller. This will not meet the experience requirements of passengers in various positions in the cabin for consistent sound quality and visual experience requirements of the display screen.

[0079] In summary, the aforementioned defects of this diffusion device affect users' visual and auditory experience, resulting in a poor user experience with smart technology. Therefore, a feasible solution is urgently needed to meet users' visual and auditory experience needs and improve their smart technology experience.

[0080] In view of this, this application provides a display device, a diffusion device, a diffusion equipment, and a terminal, relating to the field of terminal technology, specifically applicable to vehicle cabins to meet users' visual and auditory experience needs and improve users' intelligent experience.

[0081] The display device, diffusion device, diffusion equipment, and terminal provided in this application will now be described in conjunction with the accompanying drawings.

[0082] Please see Figures 2 to 5 The diagram shows a related schematic of the display device, diffusion device, and diffusion equipment provided in the embodiments of this application.

[0083] in, Figure 2 This paper shows a schematic diagram of the structure of a diffusion device provided in an embodiment of this application. Figure 3 This paper shows a schematic diagram of the split structure of a diffusion device according to an embodiment of the present application. Figure 4 A schematic diagram of another diffusion device provided in an embodiment of this application is shown. It can be understood that... Figure 3 The schematic diagram of the split structure shown can be Figure 2 The diagram shown is a schematic of the split structure corresponding to the diffusion device. Figure 2 The diffusion device shown and Figure 4 The diffusion device shown may be a schematic diagram of the same diffusion device in different states.

[0084] Figure 5 A cross-sectional schematic diagram of a display device provided in an embodiment of this application is shown. It can be understood that... Figure 5 The cross-sectional schematic diagram shown may be Figures 2 to 4 A cross-sectional schematic diagram corresponding to the display device included in the diffusion device shown.

[0085] From the above Figures 2 to 4 As can be seen, the embodiments of this application provide a diffusion device.

[0086] Specifically, the diffusion device includes, but is not limited to, at least one of the following: Display device 10, diffusion device 20.

[0087] The display device 10 is detachably connected to the diffusion device 20. The display device 10 is used to display information, and the diffusion device 20 is used to diffuse the sound.

[0088] Optionally, different groove depths and widths can be provided on one surface of the diffuser in the diffusion device 20, so that the sound waves emitted by the speaker will undergo multiple diffusion and reflection when passing through the grooves of different depths and widths on the surface, thereby realizing the propagation of diffused sound, so that users in different positions in the cabin can enjoy a similar sound quality experience and meet the users' auditory experience needs.

[0089] Optionally, when the diffusion device is applied to a personalized smart terminal, such as a vehicle, the diffusion device can be specifically installed at the vehicle's IP station, as described above. Figure 1 The location where the diffusion device is set.

[0090] It is understood that the display device 10 is detachably connected to the diffusion device 20, which facilitates subsequent maintenance and replacement of the display device 10. The display device 10 and the diffusion device 20 are decoupled from each other and can be evolved separately. If the display device 10 and the diffusion device 20 were integrally formed, then when the display device 10 malfunctions or a new sensor is needed, the entire device, which is integrally formed with the display device 10 and the diffusion device 20, would need to be disassembled. Therefore, the detachable design between the display device 10 and the diffusion device 20 in this embodiment can greatly reduce the maintenance and modification costs of the display device 10.

[0091] In one possible embodiment, as described above Figure 5 It can be seen that the above-mentioned display device 10 includes, but is not limited to: Display module 101, communication module 102.

[0092] The display module 101 includes a housing 1011 and a display screen 1012. The display screen 1012 is connected to the housing 1011, and the display screen 1012 and the housing 1011 enclose a receiving cavity 1013. The communication module 102 is disposed in the receiving cavity 1013.

[0093] Optionally, the communication module 102 is used for wireless communication, and the display module 101 is used to display information received through the communication module 102.

[0094] Understandably, the display device 10 has a built-in communication module 102, which has wireless communication capabilities, such as Bluetooth (BT) communication, Bluetooth Low Energy (BLE) communication, and Wireless Fidelity (WiFi) communication. Optionally, taking a vehicle as an example, the communication module 102 can specifically communicate wirelessly with the vehicle's cockpit domain controller (CDC), and the CDC transmits vehicle information to the display screen 1012 for display. If the display device 10 is connected to the diffusion device 20 via a wiring harness, the wiring harness will occupy the video communication interface and video communication resources. Since the total number of wired video communication interfaces and wired video communication resources is limited, it will further reduce the display resolution of other display devices in the terminal where the display device 10 is located (such as the vehicle's infotainment screen, projection optical engine, ceiling screen, etc.), affecting the user's visual experience. Therefore, in this embodiment, the wireless communication design of the display device 10 can avoid occupying the wired video communication interface and wired video communication resources. For example, it can avoid occupying the low-voltage differential signaling (LVDS) interface of the vehicle's infotainment system, thus ensuring the display resolution of the display device 10 and other display devices and guaranteeing the user's visual experience.

[0095] Furthermore, if the display device 10 is connected to the diffusion device 20 via a wiring harness, due to the installation space limitations in the vehicle environment, the wiring harness needs to be an extremely thin coaxial cable, and the wiring harness has many bends, which will lead to poor reliability of the wiring harness, affecting the normal display function of the display device 10, and further affecting the user's visual experience requirements. Therefore, the wireless communication design of the display device 10 in this embodiment can avoid the problem of poor wiring harness reliability, and can ensure the normal display function of the display device 10 and ensure the user's visual experience requirements.

[0096] Furthermore, if the display device 10 is connected to the diffusion device 20 via a wiring harness, the rotation angle of the display device 10 will be limited due to the constraint of the wiring harness during rotation, which will not meet the visual experience requirements of users at various locations. Therefore, the wireless communication design of the display device 10 in this embodiment can reduce the influence of the wiring harness constraint, making the rotation angle of the display device 10 more flexible and free, and meeting the visual experience requirements of users at various locations.

[0097] Therefore, the present application embodiment can satisfy the user's auditory experience needs by diffusing the sound through the diffusion device 20, and can satisfy the user's visual experience needs through the detachable design of the display device 10 and the wireless communication design. By detachably connecting the display device 10 to the diffusion device 20, the user's visual and auditory experience needs can be satisfied, thereby improving the user's intelligent experience.

[0098] In some embodiments, the display device 10 described above also includes a printed circuit board 103.

[0099] The printed circuit board 103 is disposed within the receiving cavity 1013, and the communication module 102 is disposed on the surface of the printed circuit board 103.

[0100] It is understandable that by placing the communication module 102 on the surface of the printed circuit board 103, no additional brackets or external wiring harnesses are needed, making the internal space structure of the display device 10 more compact. This facilitates the miniaturization of the display device 10, making it suitable for confined installation environments such as automotive applications. Furthermore, placing the communication module 102 on the surface of the printed circuit board 103 shortens the wiring distance between the communication module 102 and other modules, resulting in lower signal loss and ensuring stable communication transmission.

[0101] In some embodiments, the display device 10 may further include at least one of the following: Processing module 104, power supply 105, power management module 106, storage module 107, and at least one sensor 108.

[0102] The processing module 104 is disposed on the surface of the printed circuit board 103 and is used to process information received through the communication module 102. In this scenario, the display module 101 can specifically be used to display the information processed by the processing module 104. Optionally, the processing module 104 can specifically be a system on a chip (SoC).

[0103] It is understandable that by placing the processing module 104 on the surface of the printed circuit board 103, no additional brackets or external wiring harnesses are required, making the internal space structure of the display device 10 more compact. This facilitates the miniaturization of the display device 10, making it suitable for confined installation environments such as automotive applications. Furthermore, placing the processing module 104 on the surface of the printed circuit board 103 shortens the wiring distance between the processing module 104 and other modules, resulting in lower signal loss and ensuring the timing stability and reliability of the data processing by the processing module 104.

[0104] The power supply 105 is disposed within the receiving cavity 1013 and is used to supply power to the display device 10. Optionally, the power supply 105 can be a rechargeable power supply or a non-rechargeable power supply, and this embodiment does not limit this.

[0105] It is understood that by placing the power supply 105 within the housing cavity 1013 of the display device 10, independent power supply to the display device 10 can be achieved, ensuring the normal display function of the display device 10. Furthermore, the housing cavity 1013 provides enclosed protection for the power supply 105, preventing dust, water, oil, and impacts from foreign objects, thus avoiding external environmental corrosion of the power supply components, extending the service life of the power supply 105, and ensuring the normal display function of the display device 10.

[0106] The power management module 106 is disposed on the surface of the printed circuit board 103, and is used to manage the charging and / or discharging of the power supply 105. Optionally, the power management module 106 may specifically include a charge integrated circuit (Charge IC), a power management integrated circuit (PMIC), etc.

[0107] It is understandable that by placing the power management module 106 on the surface of the printed circuit board 103, no additional brackets or external wiring harnesses are needed, making the internal space structure of the display device 10 more compact. This facilitates the miniaturization of the display device 10, making it suitable for confined installation environments such as automotive applications. Furthermore, placing the power management module 106 on the surface of the printed circuit board 103 allows for shorter power supply traces and lower voltage drop, reducing power loss and ensuring stable power supply performance.

[0108] The storage module 107 is disposed on the surface of the printed circuit board 103, and the storage module 107 can be used to store information to be displayed by the display module 101. For example, the storage module 107 may specifically be flash memory.

[0109] It is understood that by placing the storage module 107 on the surface of the printed circuit board 103, there is no need for additional brackets and external wiring harnesses, making the internal space structure of the display device 10 compact, which is conducive to the miniaturization of the display device 10, and thus can be adapted to small installation environments such as vehicles.

[0110] At least one sensor 108 is disposed on the surface of the printed circuit board 103. Optionally, the at least one sensor 108 may specifically include at least one of the following: a carbon dioxide sensor, a fine particulate matter (PM2.5) sensor, a formaldehyde sensor, a temperature sensor, a humidity sensor, and a light sensor.

[0111] It is understood that at least one of the aforementioned sensors 108 can also be disposed on the surface of the printed circuit board 103 in the display device 10. These sensors can be integrated into the display device 10 without additional brackets and external wiring harnesses, making the internal space structure of the display device 10 compact and facilitating its miniaturization, thus adapting it to confined installation environments such as automotive installations. Furthermore, disposing of at least one of the aforementioned sensors 108 on the surface of the printed circuit board 103 enables the display device 10 to have functional expansion capabilities, such as carbon dioxide detection, PM2.5 detection, formaldehyde detection, temperature detection, humidity detection, and light detection. Moreover, the aforementioned detection information can be presented to the user through the display screen 1012 of the display device 10, enhancing the user's intelligent experience.

[0112] It should be understood that the above-mentioned processing module 104, power supply 105, power management module 106, storage module 107, and at least one sensor 108 can be disposed on the same side surface of the printed circuit board 103, or they can be disposed on different side surfaces of the printed circuit board 103 respectively. This application embodiment does not limit this.

[0113] It should be understood that the above-described processing module 104, power supply 105, power management module 106, storage module 107, and at least one sensor 108 are merely illustrative examples of several possible modules disposed on the surface of the printed circuit board 103 in the display device 10, and should not be construed as limiting the embodiments of this application.

[0114] It should be understood that any new embodiments obtained by reasonable modification, supplementation or combination of the above-mentioned processing module 104, power supply 105, power management module 106, storage module 107 and at least one sensor 108 are all within the protection scope of the embodiments of this application. In other words, more or fewer modules may be provided on the surface of the printed circuit board 103 in the above-mentioned display device 10.

[0115] In one possible embodiment, as described above Figures 2 to 4 It can be seen that the above-mentioned diffusion device 20 includes, but is not limited to: Diffuser 201, mounting base 202.

[0116] The diffuser 201 is rotatably connected to the mounting base 202, which is used to rotatably connect to a terminal (such as an IP station in a vehicle cabin). The diffuser 201 is used to diffuse the propagation of sound and is detachably connected to the display device 10, which is used to display information.

[0117] It is understandable that the diffuser 201 is rotatably connected to the mounting base 202, which can increase the propagation range of diffused sound and meet the user's auditory experience needs. In addition, the mounting base 202 is used to rotatably connect with the terminal. When the mounting base 202 rotates, it can drive the diffuser 201 to rotate together, thereby further increasing the propagation range of diffused sound and meeting the user's auditory experience needs.

[0118] Therefore, the present application embodiment can satisfy the user's visual experience needs through the display device 10, and the rotatable design of the diffuser 201 and the mounting base 202 in the diffusion device 20 can increase the propagation range of the diffused sound, thereby satisfying the user's auditory experience needs. By detachably connecting the display device 10 to the diffusion device 20, the user's visual and auditory experience needs can be satisfied, and the user's intelligent experience can be improved.

[0119] In some embodiments, the diffuser 201 rotates around a first axis 201a, and the mounting base 202 rotates around a second axis 202a, wherein the first axis 201a and the second axis 202a do not overlap.

[0120] Optionally, the mounting base 202 supports 360° rotation around the second axis 202a. Optionally, the diffuser 201 supports 360° rotation around the first axis 201a.

[0121] Optionally, the first axis 201a and the second axis 202a can be perpendicular to each other, or they can be at a certain angle to each other, or they can be parallel to each other. This application embodiment does not limit this.

[0122] It is understandable that by designing the relative positional relationship between the rotation axis of the diffuser 201 and the rotation axis of the mounting base 202, the diffuser 201 can rotate at multiple angles, increasing the range of sound propagation and meeting the user's auditory experience needs. Furthermore, the multi-dimensional rotation of the diffuser 201, along with the display device 10, increases the viewing area of ​​the displayed content, satisfying the visual experience needs of users in various positions.

[0123] In some designs, the mounting base 202 may specifically include a fixedly connected base 2021 and a storage shell 2022.

[0124] The housing 2022 has a housing cavity 2022a, the diffuser 201 is disposed in the housing cavity 2022a, and the base 2021 is used to rotate and connect with a terminal (such as an IP station in a vehicle cabin).

[0125] It is understandable that placing the diffuser 201 inside the receiving cavity 2022a can make the internal space structure of the diffuser 20 compact, which is conducive to the miniaturization of the diffuser 20 and thus can be adapted to narrow installation environments such as vehicles.

[0126] In some schemes, the aforementioned diffuser 201 is rotated to a first position (e.g., Figure 2 or Figure 3 When the diffuser 201 is positioned in the cavity, the arc-shaped outer peripheral surface of the diffuser 201 is opposite to the inner wall surface of the receiving cavity 2022a.

[0127] It is understandable that the arc-shaped outer peripheral surface of the diffuser 201 and the inner wall surface of the receiving cavity 2022a are opposite each other, so that when the diffuser 201 rotates, it will not rub against the inner wall surface of the receiving cavity 2022a, nor will the gap between the diffuser 201 and the inner wall surface of the receiving cavity 2022a be too large. This makes the internal space structure of the diffuser 20 compact, which is conducive to the miniaturization of the diffuser 20 and thus can be adapted to narrow installation environments such as vehicle-mounted.

[0128] In some designs, the aforementioned housing 2022 has an opening 2022b, which communicates with the housing cavity 2022a. In this scenario, the diffuser 201 rotates to a second position (e.g., Figure 4 When the diffuser 201 is positioned in the middle, the arc-shaped outer peripheral surface of the diffuser 201 is flush with the edge of the opening 2022b.

[0129] Optionally, the aforementioned housing 2022 is spherical, the opening 2022b is circular, and the diffuser 201 further includes a first surface and a second surface, which are connected to opposite sides of the arc-shaped outer peripheral surface, and both the first surface and the second surface are circular.

[0130] It is understandable that the arc-shaped outer peripheral surface of the diffuser 201 is flush with the edge of the opening 2022b of the housing 2022, which can ensure the overall consistency of the appearance of the diffuser 20 when the diffuser 201 rotates, thus improving the aesthetics of the diffuser 20.

Specifically, the power supply 105 can be continuously charged through the first charging unit and the second charging unit, thereby ensuring the stable power supply performance of the display device 10.

Through at least one of these electrical connection methods, continuous charging of the power supply 105 can be achieved, ensuring stable power supply performance of the display device 10.

[0140] It is understood that when the power supply 105 in the display device 10 is a rechargeable power supply, the power supply in the display device 10 can be continuously charged through the electrical connection of the first charging unit and the second charging unit, the electrical connection of the second charging unit and the third charging unit, and the electrical connection of the third charging unit with the terminal, thereby ensuring the stable power supply performance of the display device 10.

[0141] Interaction Design 2: The display device 10 and the diffusion device 20 can be connected by at least one of the following methods: magnetic connection, snap-fit ​​connection, or threaded connection.

[0142] It is understood that the display device 10 and the diffusion device 20 can be detachably connected through at least one of the above connection methods, thereby enabling the display device 10 and the diffusion device 20 to be decoupled from each other and evolve separately, reducing the maintenance and modification costs of the display device 10.

[0143] In some solutions, the detachable connection between the display device 10 and the diffusion device 20 in the above-mentioned interaction design 2 can be achieved in ways including but not limited to the following: Method A: The aforementioned housing 1011 includes a first magnetic attracting element, and the diffusion device 20 includes a second magnetic attracting element; the first magnetic attracting element and the second magnetic attracting element are magnetically connected.

[0144] It is understood that the housing 1011 includes a first magnetic element. Specifically, the housing 1011 itself may be made of a magnetic material, or the magnetic element may be glued to the surface of the housing 1011 facing away from the display screen 1012. By magnetically connecting the first magnetic element and the second magnetic element, a detachable fixed connection can be achieved between the display device 10 and the diffusion device 20.

[0145] Optionally, the housing 1011 may not include the first magnetic element. The housing 1011 may be made of a metal material that can be attracted by the second magnetic element, which can also achieve a magnetic connection between the housing 1011 and the diffusion device 20.

[0146] Optionally, the above-mentioned diffusion device 20 may not include the second magnetic element. The diffusion device 20 is made of a metal material that can be attracted by the first magnetic element, which can also realize the magnetic connection between the housing 1011 and the diffusion device 20.

[0147] Method B: The aforementioned housing 1011 includes a first structural component, and the diffusion device 20 includes a second structural component; the first structural component and the second structural component are interlocked or threaded together.

[0151] It is understood that this method C can be regarded as a combination of the above methods A and B, which can make the reliability of the detachable fixed connection between the display device 10 and the diffusion device 20 higher.
