Description

Technical Field

[0001] This invention relates to the field of smart screen audio system technology, and in particular to a smart screen audio switching method, storage medium, device and terminal equipment. Background Technology

[0002] With the rapid development of intelligent display technology, smart screens, as intelligent devices that combine portability and a large-screen experience, are gradually entering various scenarios such as homes and offices. Their form has also evolved from a single fixed form to multiple forms, among which the dual-form design combining standalone and integrated forms has become one of the mainstream market trends. The standalone form allows for portable movement and close-range use, while the integrated form, combined with a stand, enables stable placement and an immersive experience, thus meeting users' needs in different scenarios.

[0003] In existing technologies, the audio systems of multi-form smart screens mostly adopt a single speaker configuration or fixed sound effect mode. That is, regardless of the form of the device, the same set of speaker cavity and EQ (equalizer) parameters are used, which cannot adapt the acoustic output according to the form change. Although some high-end products are equipped with multiple speaker cavities, they do not achieve adaptive linkage between form and audio system. Users need to manually switch sound effect modes, which is cumbersome and cannot accurately match the acoustic characteristics of the current form.

[0004] The acoustic environment and sound production requirements of standalone and integrated forms of existing technologies are different (standalone forms require clear and focused mid-high frequency output, while integrated forms require rich and three-dimensional full-frequency output). Existing technologies use fixed sound effects, which cannot fully utilize the performance of audio hardware in different forms, resulting in poor sound quality experience, such as bass redundancy in standalone forms and thin mid-high frequency in integrated forms.

[0005] Although some products support switching between multiple EQ modes, users need to manually identify the device mode and switch manually, which increases the user's operating cost and is prone to untimely or incorrect switching, affecting the user experience.

[0006] Multi-form devices are typically equipped with multiple speaker cavities (such as a screen cavity + a base bass cavity). In existing technologies, only some cavities are used in some forms, which does not make full use of all acoustic hardware, resulting in idle hardware resources and the inability to achieve optimal sound quality output in all forms.

[0007] Low reliability of shape recognition: In the existing technology, some multi-shape devices use software recognition (such as gravity sensing) to determine the shape, which is easily affected by environmental interference (such as placement angle deviation, vibration) leading to recognition errors, which in turn causes abnormal switching of the audio system and affects the stability of use.

[0008] Therefore, the aforementioned technical defects urgently need to be addressed. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention provides a smart screen audio switching method, storage medium, device, and terminal equipment. The aim is to enable the smart screen's audio mode to switch directly according to its physical form, fully utilizing audio hardware resources and improving sound quality and ease of use. Simultaneously, it enhances the accuracy and stability of the smart screen's physical form recognition.

[0010] To address the aforementioned technical problems, a first aspect of this application provides a smart screen audio switching method, the method comprising: Acquire the status signal of the smart screen's physical form detection switch. The status signal includes a connected signal and a disconnected signal. The connected signal corresponds to the integrated form in which the smart screen and the base work together, while the disconnected signal corresponds to the standalone form in which the smart screen works alone. Based on the status signal, determine whether the smart screen is in a unified form; if so, send a unified form command to the power amplifier, and simultaneously activate the drive circuits of the built-in smart screen speaker cavity and the base bass cavity through the unified form command, so that the smart screen speaker cavity and the base bass cavity can work together to produce sound. According to the integrated form command, several preset EQ parameter modes are unlocked, so that users can manually switch them through the smart screen interface; among them, the EQ parameter modes include at least cinema mode, music mode, standard mode, and bass mode. The physical form, the activation status of the smart screen's speaker cavity and the base's subwoofer cavity, and the EQ parameter mode are displayed on the smart screen.

[0011] The smart screen audio switching method, after the step of determining whether the smart screen's physical form is in an integrated form based on the status signal, further includes: Send a stand-alone mode command to the power amplifier; According to the single-unit mode command, the drive circuit connected to the bass cavity of the base on the power amplifier is turned off, while the drive circuit connected to the smart screen speaker cavity on the power amplifier is kept on, so that the smart screen speaker cavity can produce sound independently. Based on the integrated form command, the standard mode is locked, which is only compatible with the standalone form.

[0012] The smart screen audio switching method, wherein the step of obtaining the status signal of the smart screen physical form detection switch includes: The original state signal of the smart screen physical form detection switch is acquired at least once within a preset period of time, and the preset period of time is less than or equal to an interval of 100ms. The original state signal is denoised to obtain the state signal.

[0013] The smart screen audio switching method, wherein the step of performing noise reduction processing on the original state signal to obtain the state signal further includes: Retrieve the number of interruptions from the original state signal; Determine if the number of interruptions is greater than or equal to 1. If so, determine that the connection between the smart screen and the base is unstable and generate an unstable connection signal. An alarm is generated based on the unstable connection signal, and the user is reminded to check the connection cable and physical switch via the smart screen.

[0014] The smart screen audio switching method includes the step of sending an integrated form command to the power amplifier, and simultaneously activating the drive circuits of the built-in smart screen speaker cavity and the base subwoofer cavity through the integrated form command, so that the smart screen speaker cavity and the base subwoofer cavity can work together to produce sound, including: Ambient sound is captured via an external microphone; Analyze ambient sound and identify ambient noise; Switch EQ parameter modes based on the ambient noise level in decibels.

[0015] The smart screen audio switching method includes the step of switching the EQ parameter mode according to the ambient noise decibels, comprising: Adjust the EQ parameters and gain level according to the ambient noise level (in decibels).

[0016] In the aforementioned smart screen audio switching method, the smart screen physical form detection switch is a push-button mechanical switch or a Hall sensor switch.

[0017] The second aspect of this application provides a computer-readable storage medium storing one or more programs that can be executed by one or more processors to implement the steps in any of the smart screen audio switching methods described above.

[0018] A third aspect of this application provides a body posture detection device, which includes: The acquisition module is used to acquire the status signal of the physical form detection switch of the smart screen. The status signal includes a connected signal and a disconnected signal. The connected signal corresponds to the integrated form of the smart screen and the base working together, and the disconnected signal corresponds to the standalone form of the smart screen working alone. The judgment module is used to determine whether the physical form of the smart screen is in an integrated form based on the status signal; if so, it sends an integrated form command to the power amplifier, and simultaneously activates the drive circuits of the built-in smart screen speaker cavity and the base bass cavity through the integrated form command, so that the smart screen speaker cavity and the base bass cavity can work together to produce sound. The mode switching module is used to unlock several preset EQ parameter modes according to the integrated form command, so that users can manually switch them through the smart screen interface; among them, the EQ parameter modes include at least cinema mode, music mode, standard mode, and bass mode. The output module is used to display the physical form, the activation status of the smart screen's speaker cavity and the base's bass cavity, and the EQ parameter mode on the smart screen.

[0019] A fourth aspect of this application provides a terminal device, which includes: a processor, a memory, and a communication bus; the memory stores a computer-readable program that can be executed by the processor; The communication bus enables communication between the processor and the memory; When the processor executes the computer-readable program, it implements the steps in any of the above-described smart screen audio switching methods.

[0020] Beneficial Effects: Compared with existing technologies, this invention provides a smart screen audio switching method, storage medium, device, and terminal equipment. The method includes: acquiring a status signal from a smart screen physical form detection switch; determining whether the smart screen is in a single-unit form based on the status signal; if so, sending a single-unit form command to a power amplifier, simultaneously activating the drive circuits of the built-in smart screen speaker cavity and the base subwoofer cavity; unlocking several preset EQ parameter modes according to the single-unit form command; and displaying the physical form, the activation status of the smart screen speaker cavity and the base subwoofer cavity, and the EQ parameter modes on the smart screen. This achieves adaptive switching between single-unit and single-unit forms of the smart screen audio system, eliminating the need for manual user operation, accurately matching the acoustic output requirements of both forms, fully utilizing all audio hardware resources, improving sound quality and ease of use, while ensuring high accuracy and stability in form recognition. Specifically, this invention determines the smart screen's form through a physical switch trigger and automatically switches the audio mode. The state of the physical detection switch directly corresponds to the device's form. The form detection module achieves accurate form determination by collecting switch signals. Based on the form determination result, the audio switching control module simultaneously completes the start / stop of the speaker cavity and the switching of EQ parameters. No manual operation by the user is required throughout the process, realizing "audio adaptation in response to form change". Moreover, the detection method of the physical switch ensures the reliability of form recognition and avoids switching abnormalities caused by environmental interference. Attached Figure Description

Detailed Implementation

[0022] This invention provides a method, storage medium, apparatus, and terminal device for audio switching on a smart screen. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the invention.

It should be understood that when an element is referred to as “connected” or “coupled” to another element in this application, it may be directly connected or coupled to the other element, or there may be intermediate elements. Furthermore, “connected” or “coupled” as used herein may include wireless connections or wireless coupling. The term “and / or” as used herein includes all or any units and all combinations of one or more associated listed items.

[0024] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0025] The invention will be further explained below with reference to the accompanying drawings and the description of the embodiments.

[0026] First, it should be noted that existing technologies cannot achieve adaptive linkage between form and audio system. Users need to manually switch sound effects, which is cumbersome and the sound effects cannot accurately match the acoustic requirements of different forms, resulting in poor sound quality. If users are not familiar with the operation of multi-form devices, multiple speaker cavities of the device may not be fully utilized, resulting in idle hardware resources. In addition, some devices that use software recognition (such as gravity sensing) to determine the form of the device are more complex, susceptible to environmental interference, have low recognition reliability, and are prone to audio switching abnormalities.

[0027] To address this, this solution provides a smart screen audio switching method, storage medium, device, and terminal equipment. This invention determines the smart screen's form by triggering a physical switch, and simultaneously switches the audio mode automatically. The state of the physical switch directly corresponds to the device's form. The form detection module achieves accurate form determination by collecting switch signals. Based on the form determination result, the audio switching control module simultaneously starts / stops the speaker cavity and switches EQ parameters. The entire process requires no manual user operation, achieving "audio adaptation based on form change." Furthermore, the physical switch detection method ensures the reliability of form recognition and avoids switching anomalies caused by environmental interference.

[0028] The hardware setup of this application is the foundation for the operation of the audio system. The various hardware components work together to support shape detection, audio processing, and sound generation. The main hardware configuration of this device is as follows: a smart screen main body and a base assembly. A physical detection switch and connecting cable are also installed between the smart screen main body and the base assembly.

[0029] The smart screen has at least two independent speaker cavities built into its main body. These cavities are symmetrically arranged on both sides of the screen and are mainly responsible for outputting mid-to-high frequency audio signals to meet the clear and focused sound quality requirements in standalone mode. The screen integrates a main control chip, an audio processing chip, and an audio power amplifier. The main control chip, as the core control unit, is responsible for receiving form detection signals and issuing switching commands. The audio processing chip is responsible for adjusting EQ parameters and optimizing audio signals. The power amplifier is responsible for amplifying the processed audio signals to drive the speaker cavities to produce sound.

[0030] In addition, the base assembly has a built-in independent bass speaker cavity. The cavity adopts a low-frequency enhancement design and is mainly responsible for the output of low-frequency audio sound. It is used to supplement the bass effect in the integrated form and enhance the layering and impact of the audio output. The base is connected to the smart screen through a dedicated connection cable. The connection cable interface integrates a physical detection switch to realize the form detection function.

[0031] The physical detection switch uses a push-button mechanical switch or other switching device, either separately or integrated into the connection interface between the screen and the base. The state of the physical detection switch is directly related to the connection status between the screen and the base. Taking a push-button mechanical switch as an example, when the screen and base are normally connected via the connection cable, the interface contact will press against the physical detection switch, putting it in a "pressed" state. When the screen and base are separated and the connection cable is disconnected, the physical detection switch loses pressure and automatically resets to the "unpressed" state. This switch transmits a status signal (high / low level) to the main control chip in real time, serving as the sole basis for shape determination, and is unaffected by external environmental factors (such as vibration or placement angle).

[0032] The connecting cable is a dedicated cable that combines signal transmission and physical switch triggering functions. On the one hand, it is used to realize power transmission and signal communication between the screen and the base. On the other hand, it triggers the state change of the physical detection switch through interface docking to ensure that the form detection and connection status are synchronized.

[0033] In this solution, the execution entity of a smart screen audio switching method can be a server-side device equipped with an audio switching module. The audio switching module adaptively switches the audio playback mode and EQ parameter mode based on the connection configuration between the smart screen and the base. It is understood that the execution entity in this embodiment can be a smart terminal connected to an audio switching module, such as a smartphone, smart bracelet, or server host. For example, the host obtains the status signal of the smart screen's physical form detection switch. The status signal includes a connected signal and a disconnected signal, where the connected signal corresponds to the integrated form where the smart screen and the base work together, and the disconnected signal corresponds to the standalone form where the smart screen works alone. Based on the status signal, the host determines whether the smart screen's physical form is in the integrated form. If so, it sends an integrated form command to the power amplifier, which simultaneously activates the drive circuits of the built-in smart screen speaker cavity and the base's bass cavity, enabling the smart screen speaker cavity and the base's bass cavity to work together to produce sound. Based on the integrated form command, the host unlocks several preset EQ parameter modes, allowing users to manually switch between them through the smart screen interface. The EQ parameter modes include at least Cinema Mode, Music Mode, Standard Mode, and Low-Volume Mode. The host displays the physical form, the activation status of the smart screen speaker cavity and the base's bass cavity, and the EQ parameter modes on the smart screen.

[0034] It should be noted that the above application scenarios are shown only for the purpose of understanding the present invention, and the embodiments of the present invention are not limited in any way. On the contrary, the embodiments of the present invention can be applied to any applicable scenario.

[0035] To further illustrate the invention, the following detailed description of the embodiments is provided in conjunction with the accompanying drawings.

[0036] The smart screen audio switching method provided in this embodiment is as follows: Figure 1 As shown, the method includes: Step S10: Obtain the status signal of the smart screen physical form detection switch. The status signal includes a connected signal and a disconnected signal. The connected signal corresponds to the integrated form in which the smart screen and the base work together, and the disconnected signal corresponds to the standalone form in which the smart screen works alone.

[0037] Before obtaining the status signal of the smart screen's physical form detection switch, the smart screen is first powered on to complete its initialization and allow all functional modules to enter working mode. At the same time, the audio configuration of the standalone mode is called by default, which means that at least two sets of speaker cavities on the smart screen are activated, the bass cavity on the base is turned off, and one set of EQ parameters (default standard mode) corresponding to the standalone mode is called to ensure that the device can output audio immediately after startup to meet the user's immediate needs.

[0038] Taking a push-button mechanical switch as an example, when the screen and the base are normally connected by the connecting cable, the interface connection will press the physical detection switch, making the switch in the "pressed" state. At this time, the monitoring terminal is not at a low level, so it is determined that the smart screen is in an integrated form. When the screen and the base are separated and the connecting cable is disconnected, the physical detection switch loses pressure and automatically resets to the "not pressed" state. At this time, the monitoring terminal is at a high level, so it is determined that the smart screen is in a stand-alone form.

[0039] In this embodiment, a physical detection switch is used to realize the physical shape recognition of the smart screen. The physical detection switch is not affected by environmental factors such as vibration and placement angle, and has a high accuracy rate in shape judgment. It can effectively avoid audio switching abnormalities caused by shape recognition errors, improve the working stability of the audio system, and reduce the probability of product failure.

[0040] Step S20: Based on the status signal, determine whether the physical form of the smart screen is in an integrated form; if so, send an integrated form command to the power amplifier, and simultaneously start the drive circuit of the built-in smart screen speaker cavity and the base bass cavity through the integrated form command, so that the smart screen speaker cavity and the base bass cavity can work together to produce sound. Specifically, an integrated configuration command is sent to the power amplifier (amplifier) ​​to simultaneously activate the drive circuits of the smart screen's speaker cavity and the base's bass cavity, enabling coordinated sound generation of the smart screen's mid-to-high frequencies and the base's low frequencies.

[0041] In its integrated form, the smart screen's internal cavity and the base's subwoofer cavity work together to produce sound. Combined with EQ parameter modes, this achieves a rich, three-dimensional, full-frequency sound output, suitable for immersive usage scenarios (such as watching movies or playing music in the living room). It fully utilizes the hardware performance of each speaker cavity, avoiding the poor sound quality issues of existing technologies. By fully leveraging all the speaker hardware in multi-form devices, it enhances the layering and impact of audio output, solves the problem of idle hardware resources in existing technologies, and improves the product's cost-effectiveness.

[0042] Step S30: Unlock several preset EQ parameter modes according to the integrated form command so that the user can manually switch them through the smart screen interface; among them, the EQ parameter modes include at least cinema mode, music mode, standard mode, and bass mode. While performing step S20, a command is sent to the EQ parameter storage and retrieval module to unlock all preset EQ parameter modes. Users can manually switch between different EQ parameter modes through the smart screen interface, or keep the default standard mode to adapt to different usage scenarios.

[0043] As can be seen, when it is determined that the smart screen is in the integrated form, the first step is to unlock the speaker cavity of the base and control the start and stop of the two sets of cavities of the screen and the bass cavity of the base; the second step is to switch the EQ parameter mode and control the EQ parameter storage and recall module to recall the EQ parameters of the corresponding form.

[0044] The cinema mode enhances the clarity of mid-to-high frequency vocals and the impact of low frequencies, making it suitable for various movie-watching scenarios.

[0045] Music mode can optimize the balance across the entire frequency range, highlighting vocal and instrumental details, and adapting to different music playback scenarios.

[0046] The standard mode can accommodate output across various frequency bands and is suitable for common scenarios such as everyday video and voice calls.

[0047] The Valley Bass Mode can enhance low-frequency output and improve the bass layering, making it suitable for rock, electronic music, and other music genres.

[0048] The audio signal processing module receives externally input audio signals and performs targeted processing (such as equalization adjustment and noise reduction) on the audio signals according to the currently invoked EQ parameters. The processed audio signals are amplified by the power amplifier and then transmitted to the currently activated speaker cavity to achieve audio output. The entire processing delay does not exceed 100ms to ensure that the audio and video are synchronized and avoid audio-visual desynchronization problems.

[0049] Step S40: Display the physical form, the activation status of the smart screen's speaker cavity and the base's subwoofer cavity, and the EQ parameter mode on the smart screen. Specifically, the current physical form of the smart screen, the activation status of the smart screen's speaker cavity and the base's subwoofer cavity, and the EQ parameter mode are displayed on the smart screen interface in real time, allowing the user to view the current device status. Simultaneously, the status signal of the smart screen's physical form detection switch is continuously acquired. If the device form changes (e.g., from a combined form to a standalone form, or from a standalone form to a combined form), the above steps are repeated to achieve real-time switching of the audio system.

[0050] Through the above steps, users no longer need to manually identify the device's shape or manually switch sound effect modes. The shape detection is triggered by a physical switch, and the switching of the speaker cavity and EQ parameters is completed automatically. The entire process is automated, which greatly reduces the user's operating costs and avoids problems such as untimely or incorrect switching, thereby improving the user experience.

[0051] Furthermore, after the physical form changes, it can also work in sync with the audio processing chip to receive external audio signals (such as video audio, music signals, and voice signals), and perform equalization, gain control, and noise reduction on the audio signals according to the currently invoked EQ parameters. This ensures that the audio signals are compatible with the currently activated speaker cavity, avoids problems such as distortion, noise, and volume imbalance, and optimizes the audio output effect.

[0052] Furthermore, such as Figure 2 As shown, after determining whether the smart screen's physical form is in an integrated state based on the status signal, the process also includes: Step S21: Send a stand-alone mode command to the power amplifier; Step S22: According to the single-unit mode command, turn off the drive circuit on the power amplifier connected to the bass cavity of the base, and keep the drive circuit on the power amplifier connected to the smart screen speaker cavity so that the smart screen speaker cavity can emit sound independently. Step S23: Lock the standard mode that is only compatible with standalone mode according to the integrated form command.

[0053] Specifically, a stand-alone mode command is sent to the power amplifier. Based on the stand-alone mode command, the drive circuit of the bass cavity connected to the base on the power amplifier is turned off, and only the drive circuits of the two sets of speaker cavities on the screen are kept on, ensuring that the smart screen speaker cavities emit sound independently. At the same time, a stand-alone mode command is sent to the EQ parameter storage and recall module to lock the preset EQ parameter mode that is only adapted to stand-alone mode, and prohibit the recall of other EQ parameter modes, so as to ensure that the sound effect matches the sound characteristics of the screen cavity.

[0054] Therefore, in standalone mode, the smart screen emits sound only through the speaker cavity on the screen, and with dedicated EQ parameters, it achieves clear and transparent mid-to-high frequency output, making it suitable for close-range usage scenarios (such as desktop office work and close-range movie watching).

[0055] In other embodiments, when the smart screen is in standalone mode, a standalone mode command is sent to the power amplifier. Based on this command, the drive circuit connected to the subwoofer cavity on the power amplifier is shut down, leaving only the drive circuits for the two speaker cavities of the screen intact, ensuring that the smart screen's speaker cavities emit sound independently. Simultaneously, a standalone mode command is sent to the EQ parameter storage and recall module, locking at least two preset EQ parameter modes that are only compatible with standalone mode, prohibiting the use of other EQ parameter modes, and ensuring that the sound effects match the sound characteristics of the screen's cavities. In this embodiment, at least two EQ parameter modes (standard + voice) can be unlocked. In the integrated mode, four modes are still unlocked, optimizing the EQ parameter adaptation logic.

[0056] Specifically, the EQ parameter storage and recall module has adjusted its form binding rules. In standalone mode, the standard mode (default) and voice mode are unlocked, adapting to scenarios such as desktop office work and voice calls. In all-in-one mode, four sets of EQ modes are still unlocked, and an "automatic scene matching" function has been added, which automatically switches the EQ mode based on the user's current usage scenario (such as playing videos or music). The switching logic remains unchanged; only the number of EQ bindings and the adaptation logic have been optimized. The number of unlocked EQ modes in standalone mode has increased, and the new automatic scene matching function improves the flexibility of sound quality adaptation.

[0057] Furthermore, such as Figure 3 As shown, the steps for obtaining the status signal of the smart screen physical form detection switch include: Step S11: Acquire the original state signal of the smart screen physical form detection switch at least once within a preset period of time, where the preset period of time is less than or equal to an interval of 100ms. Step S12: Perform noise reduction processing on the original state signal to obtain the state signal. Noise reduction processing avoids misjudgments caused by signal interference and continuously monitors whether the device's form changes.

[0058] Furthermore, such as Figure 4 As shown, the step of denoising the original state signal to obtain the state signal further includes: Step S111: Retrieve the number of interruptions from the original state signal; Step S112: Determine if the number of interruptions is greater than or equal to 1. If so, determine that the connection between the smart screen and the base is unstable and generate an unstable connection signal. Specifically, if an abnormal signal is detected (such as interruption of the switch signal or no output from the speaker cavity), an alarm will be issued immediately to remind the user to check the connection cable, physical switch or speaker cavity.

[0059] Step S113: Generate an alarm prompt based on the unstable connection signal, and remind the user to check the connection cable and physical switch via the smart screen.

[0060] In some embodiments, abnormalities can also be reported via sound prompts, and abnormal information can be uploaded to the cloud via a mobile app push notification. Specifically, when an abnormality (switch malfunction, cavity malfunction) is detected, the user is notified via screen and sound, and alarm information is simultaneously pushed to the bound mobile app. The alarm information includes the type of abnormality and troubleshooting suggestions, thereby improving the convenience of troubleshooting.

[0061] Furthermore, such as Figure 5 As shown, the steps of sending an integrated form command to the power amplifier, and simultaneously activating the drive circuits of the built-in smart screen speaker cavity and the base subwoofer cavity to enable the smart screen speaker cavity and the base subwoofer cavity to work together to produce sound, include: Step S24: Acquire ambient sound through an external microphone; Step S25: Analyze ambient sound and identify ambient noise; Step S26: Switch the EQ parameter mode according to the ambient noise level in decibels.

[0062] Specifically, it collects ambient noise intensity in real time; adjusts EQ parameters and gain based on noise intensity (e.g., enhances mid-high frequencies and increases volume when noise is high; optimizes low frequencies and reduces gain when noise is low) to adapt to sound quality requirements in different environments.

[0063] Furthermore, the steps for switching EQ parameter modes based on the ambient noise level in decibels include: Adjust the EQ parameters and gain level according to the ambient noise level (in decibels).

[0064] Furthermore, the physical form detection switch for the smart screen is either a push-button mechanical switch or a Hall sensor switch.

[0065] In this embodiment, the smart screen physical shape detection switch can be configured as a push-button mechanical switch or a Hall sensor switch. The Hall sensor switch can use magnetic coupling to achieve shape detection.

[0066] Specifically, a Hall sensor switch is installed at the connection cable interface, and a magnet is installed at the docking end of the base. When the smart screen is connected to the base, the magnet approaches the Hall sensor switch, triggering the sensor switch to output a low level (corresponding to the integrated form of the smart screen). When the smart screen and the base are separated, the magnet moves away from the Hall sensor switch, and the Hall sensor switch outputs a high level (corresponding to the standalone form of the smart screen). Using a Hall sensor switch can avoid the wear and tear problem of mechanical switches and improve the service life of the switch.

[0067] Push-button mechanical switches transmit signals using high / low level analog signals, while Hall sensor switches transmit signals using digital signals.

[0068] Furthermore, the status signals collected by the push-button mechanical switch or Hall sensor switch can be converted into digital signals (e.g., 00 represents not pressed, 11 represents pressed) by the encoding module, and then transmitted to the main control chip; the main control chip analyzes the signal through the decoding module to complete the state determination; the encoding / decoding module can also achieve the effect of signal noise reduction, avoiding the interference problem of analog signal transmission.

[0069] The physical form detection switch and connecting cable for the smart screen can be set separately or integrated together. In one embodiment, two independent connecting cables are set. One is a conventional signal / power connection cable, responsible for communication and power supply between the screen and the base. The other is a trigger connection cable with a physical switch integrated at the interface, which is only responsible for transmitting the form detection signal. The form determination and audio switching logic are the same as the original solution, only the hardware connection method is changed.

[0070] In Example 2, a push-button mechanical switch is integrated into the dedicated connection cable interface between the screen and the base. The switch state is directly bound to the connection state of the screen and the base. When connected, the interface presses the switch to make it "press down". When separated, the switch automatically resets to "not pressed down". There is no software recognition process, which completely avoids environmental interference such as vibration and placement angle, and ensures 100% accuracy of shape recognition.

[0071] In summary, as Figure 1As shown, this embodiment provides a smart screen audio switching method. The method acquires the status signal of the smart screen's physical form detection switch; based on the status signal, it determines whether the smart screen is in a single-unit form; if so, it sends a single-unit form command to the power amplifier, simultaneously activating the drive circuits of the built-in smart screen speaker cavity and the base subwoofer cavity; it unlocks several preset EQ parameter modes according to the single-unit form command; and it displays the physical form, the activation status of the smart screen speaker cavity and the base subwoofer cavity, and the EQ parameter modes on the smart screen. This achieves adaptive switching between single-unit and single-unit forms of the smart screen audio system, eliminating the need for manual user operation, accurately matching the acoustic output requirements of both forms, fully utilizing all audio hardware resources, improving sound quality and ease of use, while ensuring high accuracy and stability in form recognition. Specifically, this invention determines the smart screen's form through a physical switch trigger and automatically switches the audio mode. The state of the physical detection switch directly corresponds to the device's form. The form detection module achieves accurate form determination by collecting switch signals. Based on the form determination result, the audio switching control module simultaneously completes the start / stop of the speaker cavity and the switching of EQ parameters. No manual operation by the user is required throughout the process, realizing "audio adaptation in response to form change". Moreover, the detection method of the physical switch ensures the reliability of form recognition and avoids switching abnormalities caused by environmental interference.

[0072] To better implement the above methods, this application embodiment also provides a posture detection device 100, which can be integrated into an electronic device, such as a terminal, server, or personal computer. For example, in this embodiment, the device may include: a 101 acquisition module, a 102 audio switching module, a 103 posture scoring module, and a 104 output module, as detailed below (e.g.) Figure 6 ): The 101 acquisition module is used to acquire the status signal of the smart screen physical form detection switch. The status signal includes a connected signal and a disconnected signal. The connected signal corresponds to the integrated form of the smart screen and the base working together, while the disconnected signal corresponds to the standalone form of the smart screen working alone. The 102 judgment module is used to determine whether the physical form of the smart screen is in an integrated form based on the status signal; if so, it sends an integrated form command to the power amplifier, and simultaneously starts the drive circuit of the built-in smart screen speaker cavity and the base bass cavity through the integrated form command, so that the smart screen speaker cavity and the base bass cavity can work together to produce sound. The 103 mode switching module is used to unlock several preset EQ parameter modes according to the integrated form command, so that users can manually switch them through the smart screen interface; among them, the EQ parameter modes include at least cinema mode, music mode, standard mode, and bass mode. The 104 output module is used to display the physical form, the activation status of the smart screen speaker cavity and the base subwoofer cavity, and the EQ parameter mode on the smart screen.

[0073] In some embodiments, a body posture detection device 100 includes an acquisition module 101, a judgment module 102, a mode switching module 103, and an output module 104. The acquisition module 101 acquires the status signal of the smart screen's physical form detection switch. The status signal includes a connected signal and a disconnected signal, where the connected signal corresponds to the integrated form where the smart screen and base work together, and the disconnected signal corresponds to the standalone form where the smart screen works alone. The judgment module 102 determines whether the smart screen's physical form is in the integrated form based on the status signal. If so, it sends an integrated form command to the power amplifier, simultaneously activating the drive circuits of the built-in smart screen speaker cavity and the base bass cavity, so that the smart screen speaker cavity and the base bass cavity can work together to produce sound. The mode switching module 103 unlocks several preset EQ parameter modes based on the integrated form command, allowing the user to manually switch between them via the smart screen interface. The EQ parameter modes include at least cinema mode, music mode, standard mode, and bass mode. The output module 104 displays the physical form, the activation status of the smart screen speaker cavity and the base bass cavity, and the EQ parameter modes on the smart screen.
