Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] In one embodiment, such as Figure 1 As shown, this application discloses an intelligent display phonograph system. The intelligent display phonograph system includes a main control module, a phonograph, a wireless communication module, and a display module. The audio signal input terminal of the main control module is used to acquire audio data emitted by the phonograph. The data communication terminal of the main control module is connected to the data communication terminal of the wireless communication module. The wireless communication module establishes a communication path with a cloud server to acquire graphic and text display data associated with the audio data. The display signal output terminal of the main control module is connected to the signal input terminal of the display module so that the display module can push the corresponding graphic and text display data.

[0027] In this embodiment, the main control module is used to acquire audio data emitted by the phonograph. The audio signal input terminal of the main control module is connected to the audio signal output terminal of the phonograph to achieve real-time acquisition of the audio data output by the phonograph. The data communication terminal of the main control module is connected to the data communication terminal of the wireless communication module. The main control module establishes a communication path with the cloud server through the wireless communication module. The main control module can acquire graphic and text display data associated with the audio data output by the phonograph based on the wireless communication capabilities provided by the wireless communication module. The wireless communication module can achieve real-time access to the cloud server. The cloud server can transmit graphic and text display data such as song name, lyrics information, album cover, artist information, and dynamic visualization effects corresponding to the audio data to the main control module.

[0028] The main control module processes the acquired graphic and text display data, converting it into display control signals. These signals are then output from the main control module's display signal output terminal to the display module's signal input terminal. The display module, based on these control signals, synchronously displays graphic and text content corresponding to the audio data on its screen, enabling dynamic information display during audio playback. The display module can present the title, artist, lyrics progress, and dynamic visuals of the currently playing song, enhancing the user's information visualization experience while using the phonograph.

[0029] More specifically, the main control module utilizes audio recognition technology, which is applied to the processing of audio data emitted by the phonograph. After acquiring the audio data output from the phonograph in real time through the audio signal input terminal, the main control module calls a preset audio recognition module to analyze and extract features from the acquired audio data. Specifically, it can use existing audio fingerprinting algorithms (such as ACRCloud, Gracenote, or open-source Yaafe) to generate and compare fingerprints of audio segments, thereby obtaining a unique corresponding audio identifier. This audio identifier serves as crucial data for subsequent cloud requests, ensuring accurate matching of song information.

[0030] Secondly, HTTP or HTTPS network communication technology is used in the process of establishing a communication path and exchanging data between the main control module and the cloud server. The main control module constructs a data request based on the HTTP or HTTPS protocol through a network communication program, encapsulating the audio identification code generated by audio recognition, device identification information, and request type information into a standard HTTP request message, and sends it to the cloud server through the wireless communication module. The cloud server returns graphic and text display data corresponding to the audio identification code based on the received request content. Using the HTTPS protocol can effectively ensure the security and privacy of data transmission, and complies with the existing data interaction security standards for IoT devices.

[0031] Next, JSON or XML data format parsing technology is applied to the main control module's processing of data received from the cloud server. The image and text display data returned by the cloud server is encapsulated in JSON or XML format. The main control module uses an integrated JSON or XML parser to perform structured parsing on the received data, extracting information such as song title, artist, lyrics, album art address, and animation effect instructions. This information is then categorized and stored in the main control module's runtime storage unit according to a preset data structure, forming the basic dataset required for subsequent display control instructions.

[0032] Finally, UI graphics rendering technology is applied to the control of the display module by the main control module. The main control module calls existing graphics rendering engines (such as Skia, OpenGL ES, Flutter, or the native Android UI framework) and dynamically generates corresponding display control signals based on the parsed graphic and text display data and preset display templates. These display control signals can include multi-dimensional visual elements such as text, images, animations, colors, and layout. The generated display control signals are transmitted from the main control module's display signal output to the display module's signal input. Under the control of the main control module, the display module's screen presents song-related graphic and text information, achieving synchronized audio playback and graphic display, significantly improving the user experience.

[0033] Furthermore, such as Figure 2-3 As shown, the wireless communication module includes a power management unit and a communication unit. The power input terminal of the power management unit is connected to a power source, and the power output terminal of the power management unit is connected to the power input terminal of the communication unit. The communication unit includes a first antenna interface T1, a second antenna interface T9, a wireless communication chip U8, and a communication reset subunit. The first radio frequency connection terminal of the wireless communication chip U8 is connected to the first antenna interface T1, the second radio frequency connection terminal of the wireless communication chip U8 is connected to the second antenna interface T9, and the reset signal input terminal of the wireless communication chip U8 is connected to the signal output terminal of the communication reset subunit.

[0034] In this embodiment, the wireless communication chip U8 serves as the data processing core of the wireless communication module. It can receive and transmit wireless signals through the first antenna interface T1 and the second antenna interface T9, respectively, to realize the data interaction function between the wireless communication module and the cloud server. The wireless communication chip U8 supports WIFI and Bluetooth communication, has multiple wireless connectivity capabilities, and can provide a stable and reliable wireless network environment for the intelligent display and sound recording system.

[0035] Furthermore, such as Figure 4 As shown, the wireless communication chip U8 is equipped with a WIFI communication channel and a Bluetooth communication channel. The WIFI communication channel and the Bluetooth communication channel are each connected to a communication reset subunit. The communication reset subunit includes at least one first resistor, at least one second resistor, and at least one filter capacitor. The first end of the first resistor is connected to the power supply, the second end of the first resistor is connected to the first end of the filter capacitor, the second end of the filter capacitor is grounded, the first end of the second resistor is connected to the first reset control signal output terminal of the main control module, the common node between the second end of the first resistor and the first end of the filter capacitor is connected to the second end of the second resistor, and the common node between the second end of the first resistor and the first end of the filter capacitor is connected to the channel signal input terminal of the WIFI communication channel and the channel signal input terminal of the Bluetooth communication channel, respectively.

[0036] In this embodiment, as Figure 4As shown, the first resistors are R83 and R84, the second resistors are R80 and R82, and the filter capacitors are C74 and C75. The communication reset subunit is connected to the power supply through the first resistor, providing a stable operating voltage for the reset control circuit. The second resistor is connected to the first reset control signal output terminal of the main control module, enabling the on / off control of the reset signal based on the control signal issued by the main control module. The filter capacitor is placed between the first resistor and the ground point, filtering and stabilizing the reset signal to prevent malfunctions caused by signal jitter during the reset process. The communication reset subunit, constructed by the first resistor, the second resistor, and the filter capacitor, provides independent and reliable reset signals for the WIFI communication channel and the Bluetooth communication channel respectively, thereby ensuring that the wireless communication chip U8 has good reset management capabilities in different operating modes.

[0037] When the WIFI or Bluetooth communication channel in the wireless communication chip U8 needs to be reset due to an abnormality or switching requirement, the main control module can change the level state of the first reset control signal output terminal, trigger the corresponding communication reset sub-unit to act, and cause the common node potential to change, thereby applying an effective reset signal to the channel signal input terminal of the WIFI or Bluetooth communication channel, realizing precise reset control of the WIFI and Bluetooth communication channels.

[0038] Furthermore, such as Figure 5 As shown, the power management unit includes transistor QD1, MOSFET QM1, resistors R73 and R76. The controlled terminal of transistor QD1 is connected to the first enable signal output terminal of the main control module. The first terminal of resistor R73 is connected to the power supply. The second terminal of resistor R73 is connected to the first conducting terminal of transistor QD1. The second conducting terminal of transistor QD1 is grounded. The common node between the second terminal of resistor R73 and the first conducting terminal of transistor QD1 is connected to the first terminal of resistor R76. The second terminal of resistor R76 is connected to the controlled terminal of MOSFET QM1. The first conducting terminal of MOSFET QM1 is connected to the power supply. The second conducting terminal of MOSFET QM1 is connected to the power input terminal of the communication unit to supply power to the communication unit.

[0039] In this embodiment, the main control module outputs high and low level signals through the first enable signal output terminal to control the conduction and cutoff states of transistor QD1. When the first enable signal output terminal of the main control module outputs a low level, transistor QD1 is in the conduction state, the second end of resistor R73 is pulled low, and the first end of resistor R76 is also pulled low, causing the controlled terminal potential of MOSFET QM1 to decrease, and MOSFET QM1 is in the cutoff state, thereby cutting off the power supply path of the communication unit, shutting down the communication unit, and realizing the shutdown control of the wireless communication module. When the first enable signal output terminal of the main control module outputs a high level, transistor QD1 is in the cutoff state, the second end of resistor R73 is kept at a high potential with the power supply, and the first end of resistor R76 is also kept at a high potential, the controlled terminal voltage of MOSFET QM1 increases, MOSFET QM1 is turned on, the communication unit receives power supply, thereby starting the wireless communication module and restoring the wireless communication function.

[0040] Furthermore, such as Figure 6-9 As shown, the display module includes a display driver unit, an LCD reset control unit, a display power supply management unit, an LCD interface unit, and a display screen. The LCD interface unit is connected to the display screen. The PWM signal output terminal of the main control module is connected to the signal input terminal of the display driver unit. The signal output terminal of the display driver unit is connected to the drive signal input terminal of the LCD interface unit. The second reset control signal output terminal of the main control module is connected to the signal input terminal of the LCD reset control unit. The signal output terminal of the LCD reset control unit is connected to the reset signal input terminal of the LCD interface unit. The second enable signal output terminal of the main control module is connected to the signal input terminal of the display power supply management unit. The signal output terminal of the display power supply management unit is connected to the power input terminal of the LCD interface unit.

[0041] In this embodiment, the display driver unit, LCD reset control unit, display power supply management unit, LCD interface unit, and display screen are interconnected through a clear signal connection, jointly realizing dynamic control, reset management, and power supply management functions for the displayed graphic content. This enables the display module to present various information such as song title, artist, lyrics, album cover, and dynamic effects in real time based on the graphic display data acquired by the main control module, significantly improving the information display capability and human-computer interaction experience of the intelligent display audio system. Simultaneously, the organic coordination of power supply control and reset control ensures the safety, stability, and energy efficiency optimization of the display module during operation, meeting the comprehensive needs of intelligent display in various scenarios.

[0042] Furthermore, such as Figure 7As shown, the display driving unit includes a driving chip U4 and a diode D1. The signal input terminal of the driving chip U4 is connected to the PWM signal output terminal of the main control module. The driving signal input terminal of the LCD interface unit includes a positive input port and a negative input port. The first signal output terminal of the driving chip U4 is connected to the positive terminal of the diode D1, the negative terminal of the diode D1 is connected to the positive input port, and the second signal output terminal of the driving chip U4 is connected to the negative input port.

[0043] In this embodiment, the main control module outputs PWM signals with different duty cycles through the PWM signal output terminal. The driver chip U4 adjusts the amplitude and duration of the output current according to the changes in the PWM signal, thereby dynamically adjusting the backlight brightness of the display module. When the PWM signal duty cycle is high, the driver chip U4 outputs a higher drive current, and the amplitude of the drive signal received by the LCD interface unit increases accordingly, thus improving the brightness of the display screen. When the PWM signal duty cycle is low, the drive current output by the driver chip U4 decreases, the amplitude of the drive signal received by the LCD interface unit decreases, and the brightness of the display screen decreases accordingly. Diode D1 is placed between the driver chip U4 and the LCD interface unit to prevent current backflow, improve the stability and safety of the drive circuit, and ensure that the drive signal can be transmitted unidirectionally to the LCD interface unit during the operation of the display module, avoiding damage to the driver chip U4 or the main control module due to reverse voltage fluctuations.

[0044] Furthermore, such as Figure 8 As shown, the LCD reset control unit includes resistors R27 and R25 and capacitor C51. The first end of resistor R25 is connected to the power supply, the second end of resistor R25 is connected to the first end of capacitor C51, the second end of capacitor C51 is grounded, the first end of resistor R27 is connected to the second reset control signal output terminal of the main control module, the common node between the second end of resistor R25 and the first end of capacitor C51 is connected to the second end of resistor R27, and the common node between the second end of resistor R25 and the first end of capacitor C51 is connected to the reset signal input terminal of the LCD interface unit.

[0045] In this embodiment, the main control module outputs high and low level signals through the second reset control signal output terminal to control the level state of the reset signal input terminal of the LCD interface unit to the LCD reset control unit. When the second reset control signal output terminal of the main control module outputs a low level, resistor R27 transmits the low level signal to the common node, the potential of the common node decreases, and the reset signal input terminal of the LCD interface unit is simultaneously pulled low, thereby triggering the display screen to enter the reset state. At this time, capacitor C51 can filter high-frequency interference in the reset signal to avoid false resets or reset failures caused by transient voltage fluctuations.

[0046] When the second reset control signal output terminal of the main control module outputs a high level, resistor R27 transmits the high-level signal to the common node, raising the potential of the common node. This pulls the reset signal input terminal of the LCD interface unit high, causing the display to exit the reset state and enter normal operation. Resistor R25 and capacitor C51 form an RC filter network, further improving the stability of the reset signal and preventing abnormal resets caused by noise interference during system startup or operation, thus ensuring the reliability of the display module and the consistency of the display effect.

[0047] Furthermore, such as Figure 9 As shown, the power supply management unit includes transistor QL1 and MOSFET Q3. The first conducting terminal of MOSFET Q3 is connected to the power supply, and the second conducting terminal of MOSFET Q3 is connected to the power input terminal of the LCD interface unit. The controlled terminal of transistor QL1 is connected to the second enable signal output terminal of the main control module. The first conducting terminal of transistor QL1 is connected to the controlled terminal of MOSFET Q3, and the second conducting terminal of transistor QL1 is grounded.

[0048] In this embodiment, the main control module outputs a control signal through the second enable signal output terminal to achieve dynamic control of the display power supply management unit. When the second enable signal output terminal of the main control module outputs a high level, transistor QL1 is in the off state, the controlled terminal of MOSFET Q3 remains at a high potential, MOSFET Q3 is turned on, the LCD interface unit receives power through MOSFET Q3, and the display screen enters the working state. When the second enable signal output terminal of the main control module outputs a low level, transistor QL1 is turned on, the controlled terminal of MOSFET Q3 is pulled low to ground potential, MOSFET Q3 is turned off, the LCD interface unit is powered off, and the display screen stops working, thereby effectively shutting off the power supply to the display module.

[0049] Furthermore, the main control module includes a main control processing chip, an LPDDR4 memory unit, a running memory unit, and a flash memory unit.

[0050] In this embodiment, the main control processing unit uses the 328F main control chip as the implementation carrier. The 328F main control chip has multi-core processing capabilities and rich peripheral interfaces, and can support multiple functions such as audio decoding, wireless communication control, graphic display processing and human-computer interaction, ensuring that the intelligent display sound system has good performance in multi-task parallelism, real-time response and efficient processing.

[0051] The memory unit uses LPDDR4 memory units as the implementation carrier. LPDDR4 memory units have the characteristics of high bandwidth, low power consumption and fast response. They can provide real-time caching support for the main control processing unit to run the operating system, audio recognition, image and text rendering and other tasks, which significantly improves the system operating efficiency and the smoothness of user operation.

[0052] The runtime storage unit uses a 1G DDR+ runtime storage unit as its implementation carrier. The 1G DDR+ runtime storage unit is used to provide data read and write space for the main control processing unit during runtime, and supports multiple functions such as audio data caching, network communication data caching, and image and text information caching, ensuring that the system's data read and write performance meets the real-time and stability requirements under different usage scenarios.
