Sound quality is a crucial standard for judging the quality of audio equipment, including indicators such as signal-to-noise ratio, sampling bit depth, sampling frequency, and total harmonic distortion. The levels of these parameters determine the sound quality of the audio equipment. Therefore, audio equipment needs to have its operating status monitored in real time using monitoring equipment, often employing audio analyzers to monitor various parameters.
[0003] Traditional audio analysis instruments have gradually revealed several limitations in long-term practical applications. On the one hand, their monitoring accuracy is constrained by hardware performance and algorithms, making it difficult to achieve high-sensitivity and high-accuracy analysis and judgment of audio signals under complex operating conditions.

In addition, the operation interface of such devices is complex, and problems such as misoperation or low efficiency are prone to occur in actual use.

Detailed Implementation
[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0026] Example 1
[0027] like Figures 1 to 5 As shown, this is the first embodiment of the present invention. This embodiment provides an audio device operation monitoring device and its usage method, including a housing 100, a monitoring component 200 for monitoring audio devices, and a support component 300 for supporting the housing 100. The monitoring component 200 includes a signal processing module, a multi-channel signal acquisition module, an analog-to-digital conversion module, a synchronization module, a storage module, a power supply module, an alarm module, a communication module, and a touch chip. The multi-channel signal acquisition module consists of an acquisition chip, an amplifier, and a filter. The synchronization module includes a word clock module, a collaborative control module, a preprocessing module, and a data fusion module. The system is responsible for collecting various types of audio signals from the audio device under test. The signal processing module performs in-depth processing on the collected signals, including feature extraction, parameter calculation, and fault analysis. The data storage module is used to store the collected raw audio data and analysis results. One end of the housing 100 is equipped with an interface module 400, which is used to connect peripheral devices. The other end of the housing 100 is equipped with a touch screen 500 for display, control keys 600 for adjustment, and a tri-color light 700 for alarm display. The touch screen 500 is electrically connected to the touch chip, the tri-color light 700 is electrically connected to the alarm module, and the control keys 600 are electrically connected to the signal processing module.
[0028] like Figures 1 to 5As shown, the monitoring device and the audio device under test are connected via interface module 400 to ensure a stable connection and normal signal transmission. After connection, the device power is turned on, and the power module provides a stable operating voltage for the entire monitoring device. The monitoring program is started via control key 600. At this time, the multi-channel signal acquisition module starts working. The acquisition chip, amplifier, and filter work together to acquire multiple types of audio signals from the audio device under test. The acquired signals are transmitted to the signal processing module, which performs in-depth processing, including feature extraction, parameter calculation, and fault analysis. During signal processing, the word clock module, collaborative control module, preprocessing module, and data fusion module of the synchronization module ensure the synchronization and data consistency between the modules. The raw audio data and analysis results generated during processing are stored in the storage module. If the signal processing module detects a fault or abnormality in the audio device, the alarm module will be triggered, activating 700 tri-color LEDs. Different colors are displayed to indicate different fault levels. Simultaneously, the raw audio data, analysis results, and device operating status can be viewed via the touchscreen 500. The touchscreen 500, supported by a touch chip, enables convenient operation and interaction. If monitoring data needs to be transmitted to other devices or systems, it can be done through the communication module. This effectively solves the limitations of traditional audio analyzers in data transmission and remote monitoring. The communication module supports multiple communication protocols including Wi-Fi, Bluetooth, and Ethernet, allowing the device to flexibly adapt to different usage scenarios. Whether it's a portable application requiring wireless transmission or a fixed location requiring a wired connection to ensure data stability, it meets the needs. Through the communication module, monitoring data can be uploaded to a cloud server or local management system in real time, facilitating remote monitoring and data analysis of the audio equipment's operating status anytime, anywhere, greatly improving the efficiency and timeliness of audio equipment maintenance.
[0029] Example 2
[0030] Reference Figures 1 to 5 This is the second embodiment of the present invention, which is based on the previous embodiment.
[0031] In this embodiment, the signal processing module is equipped with a dual-core DSP+FPGA architecture and a built-in real-time Fourier transform engine to handle complex signal processing tasks. The fault analysis in the signal processing module adopts a three-level fault diagnosis model.
[0032] The multi-channel signal acquisition module, analog-to-digital conversion module, synchronization module, storage module, power supply module, alarm module, communication module, and touch chip are all electrically connected to the signal processing module and are all integrated on the PCB board. The communication module supports multiple communication protocols, including Wi-Fi, Bluetooth, and Ethernet, to achieve flexible communication methods. The acquisition chip of the multi-channel signal acquisition module adopts a high-precision ADC chip + adaptive impedance matching circuit, which supports ≥3 channels of synchronous acquisition.
[0033] The interface module 400 includes an input interface 410 electrically connected to the multi-channel signal acquisition module, a power interface 420 electrically connected to the power module, and a communication interface 430 electrically connected to the communication module. The interface module 400 is fixed to the surface of the back plate 120. The inner cavity of the housing 110 is also fixedly connected to a buzzer 800 electrically connected to the alarm module. The touch screen 500, control keys 600 and tri-color lights 700 are all fixed to the surface of the panel 130.
[0034] like Figures 1 to 5 As shown, the PCB board adopts a multi-layer wiring design, which effectively reduces signal interference and improves equipment stability. The signal processing module interacts with the storage module through a high-speed bus to ensure the real-time performance and accuracy of data transmission. The power module adopts a wide voltage input design to adapt to different working environments, and also has overvoltage and overcurrent protection functions to ensure safe operation of the equipment. The alarm module is linked with the buzzer 800. When an abnormal signal is detected, it immediately triggers an audible and visual alarm and uploads the alarm information through the communication module. The touch screen 500 supports multi-touch operation. Users can quickly switch monitoring modes through the control key 600. The three-color indicator 700 intuitively displays the operating status of the equipment: green indicates normal, yellow indicates warning, and red indicates fault.
[0035] Example 3
[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 This is the second embodiment of the present invention, which is based on the first two embodiments.
[0037] In this embodiment, the outer casing 100 includes a casing 110, a back plate 120 fixed to the back of the casing 110, a panel 130 fixed to the front of the casing 110, ventilation holes 140 opened on both sides of the casing 110, and a fan 150 fixed to the inner cavity of the casing 110.
[0038] Fans 150 are fixedly connected to both sides of the inner cavity of housing 110. Monitoring component 200 is fixed to the bottom of the inner cavity of housing 110. Support component 300 is fixedly connected to the bottom of housing 110. Support component 300 includes support plate 310 fixedly connected to housing 110, support feet 320 fixed around support plate 310, and fixing component 330 installed on the surface of support feet 320.
[0039] The fixing assembly 330 includes a support base 331 fixed to the bottom of the support foot 320, a silicone adsorption pad 332 installed in the inner cavity of the support base 331, a pressure plate 333 located in the inner cavity of the silicone adsorption pad 332, a nut 334 fixed to the top of the support foot 320, a screw 335 meshing with the nut 334, and a knob 336 fixed to the top of the screw 335. The end of the knob 336 away from the screw 335 extends into the inner cavity of the silicone adsorption pad 332 and is rotatably connected to the pressure plate 333.
[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a rubber pad is provided between the housing 110 and the support plate 310, and the support foot 320 is used to provide support. It can be fixed on the table by the fixing component 330. The monitoring device is placed in a suitable position on the table by the support component 300. Then, the knob 336 is rotated. Since the knob 336 is fixedly connected to the screw 335 and the screw 335 is engaged with the nut 334, rotating the knob 336 will cause the screw 335 to move downward, thereby pushing the pressure plate 333 to move downward in the inner cavity of the silicone adsorption pad 332. The silicone adsorption pad 332 will be squeezed and better adsorbed on the table. At the same time, the pressure plate 333 will exert a certain pressure on the table, which will enhance the stability of the fixation. The rubber pad provided between the housing 110 and the support plate 310 can play a role in shock absorption and buffering, reducing the impact of vibration generated during the operation of the device on the device itself and the fixation state. The cooperation of the ventilation hole 140 and the fan 150 is conducive to heat dissipation during the operation of the device, ensuring that the internal components of the device work in a suitable temperature environment and extending the service life of the device.
