[0048] 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. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] With the rapid development of technology, in the automotive field, the application of in-vehicle rear entertainment screens is becoming more and more widespread. Users can sing karaoke, operate the rear entertainment screen, and so on during the ride, thereby enhancing the riding experience.

[0050] In some embodiments, an entertainment screen is installed in the rear seats of the vehicle, and the vehicle is also equipped with an independent remote control and microphone. The remote control is connected to the entertainment screen in the rear seats, so the entertainment screen can be controlled by the remote control. In addition, the microphone is connected to the acquisition device through a USB interface, so that users can sing karaoke through the external microphone.

[0051] However, users need to use a remote control and a microphone separately to meet different operational and entertainment needs. For example, when a user wants to sing karaoke, they need to plug in a microphone, and when they need to control the entertainment screen, they need to plug in a remote control. This not only increases the complexity of device management and makes it easy for devices to be lost, but also requires frequent switching between different devices during use, which makes it inconvenient for users.

[0052] To address the aforementioned technical deficiencies, this application provides a remote control that integrates the remote control and microphone into one unit, thereby solving the problems of cumbersome storage and inconvenient operation of the remote control and microphone, and improving the user experience.

[0053] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0054] Please refer to Figures 1 to 3 As shown in the embodiment of this application, the remote control 10 is applicable to a vehicle. The vehicle has a display screen that can be used for entertainment. The remote control 10 has a remote control function and a microphone function, so as to interact with the display screen on the vehicle through the remote control 10 to remotely control the display screen or to sing karaoke through the microphone function, so as to meet the user's entertainment needs.

[0055] Please continue to refer to Figures 1 to 3As shown, the remote controller 10 provided in this application embodiment includes a remote controller body 100, which includes a housing 110 and a signal interaction unit 120. The signal interaction unit 120 is disposed inside the housing 110 and is configured to transmit remote control commands to the display screen and receive feedback information to realize the remote control function.

[0056] For example, the signal interaction unit 120 includes a circuit board 121, a signal transmitter 122, and a signal receiver. Both the signal transmitter 122 and the signal receiver are electrically connected to the circuit board 121. In addition, the housing 110 has a button area with multiple buttons 113. The multiple buttons 113 include, but are not limited to, number keys, directional keys, and function keys. The function keys include, but are not limited to, power keys, menu keys, and volume control keys. The number keys, directional keys, and function keys are electrically connected to the circuit board 121. In this way, the user can operate the buttons 113 in the button area and transmit remote control commands to the display screen through the signal transmitter 122 to control the display screen. The signal receiver is used to receive feedback information from the display screen, thereby realizing signal interaction between the signal interaction unit 120 and the display screen to achieve remote control function.

[0057] Please continue to refer to Figures 1 to 3 As shown, the remote control 10 provided in this application embodiment also includes a microphone module 200. The microphone module 200 is integrated on the remote control body 100. The microphone module 200 is configured to collect voice signals to realize the microphone function. In this way, the remote control 10 has both remote control function and microphone function, which solves the problem of complicated storage when the remote control 10 and the microphone are two independent components.

[0058] In addition, the remote control 10 also includes a switch key 300, which is movably disposed on the outer surface of the housing 110. The switch key 300 is configured to change the working state of the remote control 10 so that the remote control 10 can switch between remote control function and microphone function. In this way, the user can quickly switch between remote control function and microphone function by operating the switch key 300, which improves the convenience of switching between remote control function and microphone function.

[0059] In practice, when switching to the remote control function via the operation switch key 300, the user can control the display screen by operating the button 113 in the button area; when switching to the microphone function, the microphone function is activated, and the user can sing karaoke, etc.

[0060] For example, the switch key 300 is connected to the power supply that powers the microphone module 200, so that the microphone module 200 can be switched between being powered on and off by the switch key 300. For example, the switch key 300 can be switched by pressing to enable or disable the microphone module 200, thereby enabling the switching between the microphone function and the remote control 10 function. That is, when the microphone module 200 is powered on, it switches to the microphone function, and when the microphone module 200 is powered off, it switches to the remote control function.

[0061] For example, the power supply has a switch trigger point, and the switch key 300 has a trigger part. The switch can move between the trigger position and the de-trigger position. When the switch key 300 is pressed and moves to the trigger position, the trigger part contacts the switch trigger point to turn on the power. When the switch key 300 is released, the trigger part de-triggers to turn off the power. For details, please refer to the relevant technology, which will not be elaborated here.

[0062] Therefore, in this embodiment, by integrating a microphone module 200 onto the remote control body 100, the remote control body 100 has a remote control function, and the microphone module 200 has a microphone function. A switching key 300 is provided on the outer surface of the housing 110, allowing the user to quickly switch between the remote control function and the microphone function by operating the switching key 300, thus improving the convenience of switching between the remote control function and the microphone function. In addition, the remote control 10 has both remote control and microphone functions, which reduces the complexity of storage and improves the convenience of operation, thereby enhancing the user experience.

[0063] Please continue to refer to Figures 1 to 3 As shown, the switch key 300 can be set on the side of the housing 110. On the one hand, it can save space on the front of the housing 110 (such as the side where the button area is located) and improve the compactness of the structure. On the other hand, the switch key 300 is set on the side, making it easy for users to distinguish between the button 113 in the button area and the switch key 300. Users can operate the switch key 300 from the side to switch between the remote control function and the microphone function.

[0064] In some embodiments, the microphone module 200 includes a microphone housing 210 and a voice acquisition unit 220. The microphone housing 210 is disposed on the top of the housing 110, and the voice acquisition unit 220 is disposed inside the housing 110. The microphone module 200 includes, but is not limited to, a digital microphone. A digital microphone first converts sound into a digital signal, and then transmits it after digital encoding and compression. Digital microphones typically integrate components such as analog-to-digital converters, digital signal processing, and digital interfaces. For details, refer to the structure and working principle of digital microphones in related technologies.

[0065] For example, the voice acquisition unit 220 includes a voice acquisition device and an audio processing circuit. The voice acquisition device has an audio signal output pin, and the audio processing circuit includes a preamplifier and a filter, etc. The audio signal output pin is connected to the audio processing circuit. The preamplifier and the filter are used to amplify and filter the weak audio signal acquired by the voice acquisition device, thereby improving the audio quality.

[0066] Please refer to Figure 4 As shown, the microphone housing 210 has multiple pickup hole arrays, each pickup hole array including multiple pickup holes 211. The multiple pickup holes 211 in the pickup hole array are arranged to form a rhombus structure. In addition, the original outline shape of the pickup hole 211 can also be rhombus. For example, the maximum opening size of the pickup hole 211 is less than or equal to 3mm. This can improve the quality of the microphone's voice acquisition and ensure that the user's voice can be accurately captured in various usage scenarios. For example, even when the user is far away from the display screen or there is a certain amount of noise in the surrounding environment, the voice acquisition quality of the voice acquisition unit 220 can be guaranteed.

[0067] The voice acquisition unit 220 is located inside the housing 110 near the pickup hole 211, which facilitates the acquisition of voice signals, thereby improving the sensitivity of voice acquisition and enhancing the user experience.

[0068] In addition, to prevent dust and debris from entering the microphone module 200, a dustproof mesh is provided at the pickup hole 211. The dustproof mesh covers the corresponding pickup hole 211, thereby isolating dust and debris from the outside of the microphone housing 210, so as to prevent dust and debris from entering the inside of the microphone housing 210 and affecting the reliability and voice acquisition performance of the voice acquisition unit 220.

[0069] Please refer to Figure 2 As shown, the signal interaction unit 120 is located above the voice acquisition unit 220 along the thickness direction of the housing 110 (e.g., the direction perpendicular to the surface of the button area). This improves the utilization rate of the space inside the housing 110 and thus enhances the structural compactness.

[0070] Please continue to refer to Figure 2 As shown, the remote controller 10 also includes a shield 400, which is disposed between the voice acquisition unit 220 and the signal interaction unit 120. The shield 400 is configured to shield the electromagnetic interference generated by the signal interaction unit 120, thereby reducing the impact of electromagnetic interference on the audio signal acquired by the voice acquisition unit 220.

[0071] Please continue to refer to Figure 2 and Figure 5As shown, the signal interaction unit 120 includes a circuit board 121, a signal transmitter 122, and a signal receiver. Both the signal transmitter 122 and the signal receiver are located at the end of the circuit board 121 near the top of the housing 110 and are electrically connected to the circuit board 121 to ensure effective signal transmission. The pins of the signal transmitter 122 can be directly connected to a driving circuit on the circuit board 121 near the pins of the signal transmitter 122. The driving circuit includes, but is not limited to, a driving chip, used to amplify the control signal output by the microcontroller in the signal interaction unit 120, thereby driving the signal transmitter 122 to operate. A shielding member 400 is disposed between the circuit board 121 and the voice acquisition unit 220, and along the thickness direction of the housing 110, the projected area of ​​the shielding member 400 covers the coverage area of ​​the circuit board 121. This improves the reliability of the shielding member 400 in shielding electromagnetic interference.

[0072] For example, the signal transmitter 122 includes, but is not limited to, an infrared transmitter, the signal receiver includes, but is not limited to, an infrared receiver, and the shield 400 includes, but is not limited to, at least one of copper foil, aluminum foil, steel foil, and nickel foil, thereby isolating the voice acquisition unit 220 and the signal transmitter 122 by the shield 400 to reduce the impact of electromagnetic interference on the audio signal.

[0073] It is understandable that by setting a shield 400 between the signal transmitter 122 and the voice acquisition unit 220, that is, by setting the signal transmitter 122 and the voice acquisition unit 220 on opposite sides of the shield 400, the voice acquisition unit 220 and the signal transmitter 122 are kept as far apart as possible, and differential signal transmission is used, thereby reducing the impact of electromagnetic interference and avoiding the impact of electromagnetic interference on the acquired audio signal.

[0074] In some embodiments, the buttons 113 of the button area are distributed on the side of the circuit board 121 facing the button area, while the button area can be located on the side of the housing 110 facing the user for easy operation. In addition, the buttons 113 can be membrane buttons 113, which are small in size and can save space, thereby improving the compactness of the structure.

[0075] In addition, the inner wall of the housing 110 has at least two limiting posts 114, and the shield 400 is fixedly connected to the limiting posts 114. That is, the shield 400 is fixed on the limiting posts 114 to limit and fix the shield 400, thereby improving the positional reliability and stability of the shield 400 and further avoiding the influence of electromagnetic interference on the audio signal collected by the voice acquisition unit 220.

[0076] For example, at least two limiting posts 114 are spaced apart on the inner wall surface of the housing 110. The cross-section of the limiting posts 114 includes, but is not limited to, circles, ellipses, quadrilaterals, or polygons. At the same height position of the at least two limiting posts 114, there are locking protrusions or slots. The shielding member 400 has locking holes through which the limiting posts 114 can pass. When the shielding member 400 moves to the locking protrusion or slot, it can be locked at the locking protrusion or slot to fix and limit the shielding member 400. Of course, the locking holes on the shielding member 400 can be connected to the limiting posts 114 by an interference fit to achieve limiting and fixing.

[0077] To reduce manufacturing costs, the housing 110 and at least two limiting posts 114 are integrated into one structure. For example, the adjustable housing and at least two limiting posts 114 can be integrated into one structure by injection molding or casting. This reduces the manufacturing process and thus lowers manufacturing costs.

[0078] In some embodiments, the signal interaction unit 120 further includes a chip and a signal processor, which are disposed on the circuit board 121 near the central area. The signal transmitter 122 and the signal receiver are respectively disposed on one end of the circuit board 121 near the microphone module 200. The signal transmitter 122 and the signal receiver are electrically connected to the signal processor, and the signal processor is electrically connected to the chip. In this way, the signal transmission path can be shortened to reduce external interference to the signal transmission.

[0079] In addition, at least one of the housing 110 and the microphone housing 210 is provided with a signal transmission window at a position corresponding to the signal transmitter 122. Correspondingly, at least one of the housing 110 and the microphone housing 210 is provided with a signal reception window at a position corresponding to the signal receiver, thereby facilitating signal transmission and reception and improving the reliability of signal transmission and reception.

[0080] It should be noted that the layout of each component in the signal interaction unit 120 and each device in the voice acquisition unit 220 inside the housing 110 avoids mutual compression or affecting the assembly of the housing 110. Under the premise of ensuring reasonable layout, the compactness of the structure and the improvement of space utilization are guaranteed.

[0081] In some embodiments, the remote controller 10 further includes a rechargeable battery 500, and the housing 110 has a charging interface. The rechargeable battery 500 is selectively electrically connected to the signal interaction unit 120 and the voice acquisition unit 220. The rechargeable battery 500 is configured to provide power to the signal interaction unit 120 and the voice acquisition unit 220. In this way, when the remote controller 10 cannot be plugged into an external power source, the rechargeable battery 500 can provide power to the remote controller 10 to meet the power demand.

[0082] In addition, the housing 110 also has an indicator light, which is electrically connected to the rechargeable battery 500. The indicator light is configured to indicate the power level of the rechargeable battery 500. For example, the brightness of the indicator light is greater when the rechargeable battery 500 is fully charged than when it is not fully charged; or, the indicator light is on when the rechargeable battery 500 is low on power, and off when the rechargeable battery 500 is fully charged.

[0083] Please continue to refer to Figures 1 to 3 As shown, the outline of the microphone housing 210 is a rotating structure. For example, the outline shape of the microphone housing 210 is a circular, elliptical or other structure, or the outline shape of the microphone housing 210 can also be any shape such as a rectangle or a polygon.

[0084] To facilitate the inspection and maintenance of the internal components of the remote controller 10, in this embodiment of the application, the microphone housing 210 is detachably connected to the housing 110. For example, the microphone housing 210 has a first latching part, and the housing 110 has a second latching part. The first latching part is configured to latch with the second latching part. For example, the first latching part is one of a buckle and a slot, and the second latching part is the other of a buckle and a slot.

[0085] In addition, to improve the aesthetics of the remote control 10, the first snap-fit ​​part is located on the back of the microphone housing 210 (for example, on the side away from the button area of ​​the housing 110), and the second snap-fit ​​part is located on the side of the housing 110 away from the button area. This can improve the overall aesthetics of the remote control 10.

[0086] Please refer to Figure 2 As shown, the housing 110 includes an upper housing 111 and a lower housing 112. The upper housing 111 and the lower housing 112 together form a housing cavity for accommodating the signal interaction unit 120 and the voice acquisition unit 220. The upper housing 111 and the lower housing 112 can be detachably connected by means of snap-fit, magnetic attraction, threaded connection, etc., so as to facilitate the disassembly of the housing 110 for maintenance, repair and replacement of the signal interaction unit 120 and the voice acquisition unit.

[0087] For example, the limiting post 114 is disposed on the upper housing 111 and is integrally formed with the upper housing 111; or, the limiting post 114 may also be soldered onto the circuit board 121, without specific restrictions.

[0088] This application embodiment also provides a vehicle, including a vehicle body and a remote controller provided in the above embodiments. The vehicle body includes, but is not limited to, cars, trucks, buses, coaches, trains, airplanes, ships, etc. The vehicle body has a display screen, and the display screen has a main control unit. The main control unit includes a signal receiving end and a signal processing unit. The signal receiving end is electrically connected to the signal processing unit so that the remote controller sends a remote control command to the display screen, and the signal processing unit receives the remote control command through the signal receiving end to realize the control of the display screen.
