Description

Technical Field

[0001] This invention relates to the field of intelligent adjustment technology for audio devices, specifically a system that automatically adjusts the external speaker volume and sound effects based on the wind noise level. Background Technology

[0002] When using outdoor audio equipment, wind noise is the main interference factor affecting the listening experience. Traditional audio equipment noise processing solutions have several limitations: First, they mostly employ active noise cancellation technology, which generates inverse sound waves to cancel out environmental noise. However, this "sound-to-cancele" approach can make the sound feel unnatural to users, and some people may find it difficult to adapt. Furthermore, in high-speed activities such as running or cycling, it can isolate external environmental sounds (such as vehicle horns or warnings from others), posing a safety hazard. Second, existing technologies do not specifically optimize for wind noise, often treating it along with other environmental noises. Adjustments are limited to volume and do not consider sound effect adaptation. This results in audio content (especially human voices and low-frequency sound effects) being masked by wind noise when it is loud, making it difficult to hear clearly. Third, the accuracy of wind noise acquisition is insufficient. Microphones are often placed far from the speaker, resulting in weak wind noise targeting in the mixed signal and low separation and recognition accuracy. Fourth, the adaptability is limited. Algorithms do not incorporate the characteristics of wind noise at different wind speeds and directions, resulting in a lack of scene-specific adaptability in adjustment effects. Fifth, interactivity is poor. Most only support local operation and cannot remotely customize thresholds and sound effect parameters, making it difficult to meet users' personalized needs.

[0003] While some related patented technologies already exist in the industry, significant shortcomings remain: Patent CN202210876543.9 (A Noise Adjustment System for Outdoor Audio Equipment): The active noise cancellation technology is used to cancel wind noise and environmental noise, but there are problems such as unrealistic sound and safety issues; only the volume is adjusted without optimizing the sound effect, and the audio clarity is insufficient in windy environments; the microphone is set on the edge of the device casing, far away from the speaker, and the wind noise collection is not targeted.

[0004] Patent CN202121987654.7 (Intelligent Noise Reduction External Speaker): It supports noise adjustment, but does not separately identify wind noise, and treats all environmental noise in a unified manner, resulting in a lack of targeted adjustment; the sound effect mode is fixed and cannot be dynamically switched according to the wind noise level, resulting in poor adaptability; it has no remote interaction function, making it difficult to meet users' personalized needs.

[0005] Patent CN202320567890.1 (Outdoor Audio Intelligent Volume Adjustment Device): Adjusts volume only based on the total intensity of ambient noise, without distinguishing between wind noise and other noises, resulting in poor adjustment effect when wind noise interferes alone; Uses a single microphone to collect noise, which has a limited collection range and is prone to missing wind noise from different directions; No sound effects are adapted and optimized, resulting in low audio content recognition when wind noise is high.

[0006] Patent CN202010987654.2 (Noise Adaptation System for Sports Audio Equipment): It does not have a built-in wind noise feature database, the algorithm has limited adaptability and cannot cope with wind noise changes in different outdoor scenarios; the volume adjustment uses a stepped switching, which is abrupt; there is no signal preprocessing link, and interference noise in the collected signal affects the accuracy of adjustment.

[0007] The aforementioned existing technologies have not solved the core problems of "accurate wind noise identification, coordinated adjustment of volume and sound effects, preservation of ambient sound, personalized adaptation, and safety and reliability," and are difficult to meet the usage needs of outdoor audio equipment in windy environments. There is an urgent need for a targeted and optimized intelligent adjustment system. Summary of the Invention

[0008] The purpose of this invention is to provide a system that automatically adjusts the external speaker volume and sound effects based on the strength of the wind noise, solving the problems of unrealistic sound, safety hazards, low accuracy of wind noise recognition, volume adjustment without sound effect optimization, and poor adaptability and interactivity of traditional solutions. Through an integrated design that accurately collects and identifies wind noise, dynamically adjusts volume and sound effects in tandem, preserves ambient sound, and supports personalized customization, the system achieves both optimized audio experience and safe use in windy environments, improving the system's adaptability and ease of use.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a system for automatically adjusting the external speaker volume and sound effect according to the wind noise level, comprising a wind noise acquisition module, an audio processing module, a main control module, and an external speaker module. Each module establishes a signal transmission connection in sequence. By acquiring and accurately identifying the wind noise around the speaker, the system dynamically adjusts the external speaker volume and sound effect type according to the wind noise level, without canceling out the wind noise to preserve the perception of environmental sound, thus solving the problems of existing noise reduction solutions being unrealistic, affecting safety, and not adapting to wind noise adjustment sound effects.

[0010] Preferably, the wind noise acquisition module establishes a real-time signal transmission connection with the audio processing module. The wind noise acquisition module uses at least one microphone placed around the speaker to accurately pick up the mixed signal of environmental noise and wind noise near the speaker and transmit the mixed signal to the audio processing module without distortion. This is different from the existing solution where the microphone is placed far away from the speaker, which leads to inaccurate wind noise acquisition. This ensures the relevance and authenticity of the wind noise signal acquisition.

[0011] Preferably, the audio processing module establishes a data interaction connection with the main control module. The audio processing module has a built-in dedicated DSP audio algorithm to separate and identify wind noise and environmental noise from the received mixed signal. By extracting key parameters such as the frequency characteristics and amplitude changes of wind noise, the wind noise level and grade are determined. The identification results and grade determination data are transmitted to the main control module. At the same time, the module receives adjustment instructions from the main control module to optimize the algorithm's adaptability, overcoming the shortcomings of existing technologies that do not separately separate and identify wind noise.

[0012] Preferably, the main control module establishes a control signal transmission connection with the external speaker module. The main control module pre-stores volume adjustment thresholds and sound effect parameters corresponding to multiple wind noise levels. After receiving the wind noise level data transmitted by the audio processing module, it matches the corresponding volume adjustment command and sound effect switching command and transmits them to the external speaker module in real time to realize synchronous dynamic adjustment of volume and sound effect, which is different from the existing technical solution that only adjusts the volume without associating sound effect optimization.

[0013] Preferably, the wind noise acquisition module includes multiple distributed microphones, which are evenly arranged around the speaker to form a 360° wind noise acquisition area. The signals acquired by each microphone are transmitted to the signal integration unit through an internal synchronization link. After consistency calibration, the signals are aggregated and transmitted to the audio processing module to ensure that wind noise from different directions can be accurately captured, thus solving the problem of limited acquisition range and wind noise omission by a single microphone.

[0014] Preferably, the DSP audio algorithm of the audio processing module has a built-in wind noise feature database, which stores wind noise signal samples corresponding to different wind speeds and directions. By comparing and matching the real-time collected wind noise signals with the database samples, the accuracy of wind noise separation and recognition is improved. At the same time, it supports online updating of sample data through the main control module to adapt to the wind noise characteristics of different outdoor scenarios, breaking through the limitation of single adaptability of existing algorithms.

[0015] Preferably, the main control module has a built-in threshold setting unit and a sound effect parameter configuration unit. The threshold setting unit allows users to customize multiple wind noise level thresholds, and the sound effect parameter configuration unit pre-stores multiple sound effect modes such as high-frequency enhancement sound effect, equalization sound effect, and low-frequency enhancement sound effect. The main control module dynamically calls the corresponding sound effect mode according to the wind noise level. When the wind noise level is higher than the preset high threshold, the high-frequency enhancement sound effect is called, and when the wind noise level is lower than the preset low threshold, the equalization or low-frequency enhancement sound effect is called to meet the user's personalized needs.

[0016] Preferably, the external speaker module includes an audio amplification unit and a sound effect processing unit. The audio amplification unit receives volume adjustment commands from the main control module and adjusts the output power through adaptive gain control technology to achieve smooth volume adjustment without abruptness. The sound effect processing unit receives sound effect switching commands and switches the frequency response curve of the audio signal in real time to ensure that the audio content is clearly distinguishable in windy environments, which is different from the problem of existing sound effect adjustment being lagging or ineffective.

[0017] Preferably, a signal preprocessing link is set between the audio processing module and the wind noise acquisition module to perform preprocessing operations such as noise reduction filtering and amplitude normalization on the raw signal acquired by the microphone, thereby removing interference noise during signal transmission and improving the accuracy of subsequent wind noise separation and identification. At the same time, the preprocessing parameters can be dynamically adjusted according to the feedback from the main control module to adapt to the signal acquisition requirements in different environments.

[0018] Preferably, the main control module establishes a wireless communication connection with an external terminal, allowing users to view the current wind noise level, volume, and sound effect status through the external terminal. It also allows users to remotely modify the wind noise level threshold, customize sound effect parameters, and enable or disable the automatic adjustment function, forming a closed-loop control link of "collection-identification-adjustment-feedback". This improves the ease of use and flexibility of the system, unlike existing systems that only support local operation and have poor interactivity.

[0019] This invention provides a system for automatically adjusting the external speaker volume and sound effects based on wind noise levels. It offers the following advantages: 1. This invention uses a distributed microphone layout around the speaker in the wind noise acquisition module to capture the mixed signal of wind noise and environmental noise near the speaker in 360°, avoiding interference from irrelevant noise; the audio processing module separates and identifies wind noise through a dedicated DSP algorithm, and compares it with the wind noise feature database to accurately determine the wind noise level, providing a reliable basis for adjustment, and overcoming the defects of inaccurate acquisition and ambiguous identification of traditional equipment.

[0020] 2. The main control module of this invention dynamically matches and adjusts the strategy according to the wind noise level. When the wind noise is high, the volume is increased and the high-frequency enhancement sound effect is switched (high frequencies are more penetrating) to ensure that the audio is clear and distinguishable. When the wind noise is low, the volume is reduced and the equalization or low-frequency enhancement sound effect is switched to avoid excessive volume causing auditory fatigue. The wind noise is not canceled throughout the process, and the perception of environmental sound is preserved, which not only ensures outdoor use safety, but also makes the listening experience more natural and comfortable.

[0021] 3. This invention supports user-defined wind noise level thresholds, volume adjustment ranges, and sound effect parameters to adapt to the auditory preferences of different users; the algorithm supports online updates of wind noise feature samples, which can adapt to the wind noise characteristics of different wind speeds and directions outdoors, breaking through the limitation of single adaptability of traditional algorithms; the external speaker module adopts adaptive gain control technology, the volume adjustment is smooth and without abruptness, and the sound effect switching is real-time responsive.

[0022] 4. The main control module of this invention communicates wirelessly with external terminals, allowing users to remotely view wind noise levels, volume, and sound effect status, and modify settings or enable / disable automatic adjustment functions at any time; forming a closed-loop link of "collection-identification-adjustment-feedback", the system can optimize algorithms based on user operation feedback, improve adjustment accuracy, and greatly enhance the flexibility and convenience of use.

[0024] 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.

[0025] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Example

[0026] A preferred embodiment of the present invention is a system for automatically adjusting external speaker volume and sound effects based on wind noise. Figure 1-10 As shown: A system for automatically adjusting external speaker volume and sound effects based on wind noise levels includes a wind noise acquisition module, an audio processing module, a main control module, and an external speaker module. Each module establishes a signal transmission connection in sequence. By acquiring and accurately identifying wind noise around the speaker, the system dynamically adjusts the external speaker volume and sound effect type according to the wind noise level. It does not cancel out wind noise to preserve the perception of ambient sound, thus solving the problems of existing noise reduction solutions being unrealistic, affecting safety, and not adapting to wind noise adjustment sound effects.

[0027] The wind noise acquisition module establishes a real-time signal transmission connection with the audio processing module. The wind noise acquisition module uses at least one microphone placed around the speaker to accurately pick up the mixed signal of ambient noise and wind noise near the speaker, and then processes it using a formula. The acquired analog signals are converted into sound pressure level data (wherein) This is the microphone output voltage. The voltage value corresponding to the standard reference voltage is transmitted to the audio processing module without distortion. This is different from the existing solution where the microphone is placed far away from the speaker, resulting in inaccurate wind noise acquisition. This ensures the relevance and authenticity of the wind noise signal acquisition.

[0028] The audio processing module establishes a data interaction connection with the main control module. The audio processing module has a built-in dedicated DSP audio algorithm, which first uses a frequency domain separation formula. (in This represents the frequency domain value of the wind noise signal. For the frequency domain values ​​of the mixed signal, Separate wind noise from ambient noise (using the frequency domain value of ambient noise), and then use the wind noise level determination formula. ( The average wind noise pressure level is calculated within a sampling time window (ranged from 0.5 to 1 second) to determine the wind noise level and grade. The identification results and grade determination data are transmitted to the main control module. At the same time, the adjustment instructions fed back by the main control module are received to optimize the algorithm's adaptability and overcome the shortcomings of existing technologies that do not separately identify wind noise.

[0029] The main control module establishes a control signal transmission connection with the external speaker module. The main control module pre-stores volume adjustment thresholds and sound effect parameters corresponding to multiple wind noise levels, and uses a volume adjustment formula. (in This is the baseline volume when there is no wind noise. The adjustment coefficient is set to a value between 1.2 and 1.5. With a baseline wind noise level of 40dB(A), after receiving wind noise level data transmitted from the audio processing module, the target volume is calculated using this formula, and the corresponding sound effect switching command is matched and transmitted to the external speaker module in real time, realizing synchronous dynamic adjustment of volume and sound effect, which is different from the existing technical solutions that only adjust the volume without linking sound effect optimization.

[0030] The wind noise acquisition module includes multiple distributed microphones, which are evenly arranged around the speaker to form a 360° wind noise acquisition area. The noise is then collected using a signal fusion formula. ( For the number of microphones, The signal collected by each microphone (sound pressure level collected by a single microphone) is fused and processed, and after consistency calibration, it is summarized and transmitted to the audio processing module to ensure that wind noise from different directions can be accurately captured, thus solving the problem of limited collection range and wind noise omission by a single microphone.

[0031] The audio processing module's DSP audio algorithm incorporates a wind noise feature database. This database stores wind noise signal samples corresponding to different wind speeds and directions, and uses correlation matching formulas... ( This is a real-time wind noise frequency domain signal. It calculates similarity for the frequency domain signals of database samples, improving the accuracy of wind noise separation and recognition. It also supports online updating of sample data through the main control module, adapting to the wind noise characteristics of different outdoor scenarios, and breaking through the limitation of single adaptability of existing algorithms.

[0032] The main control module has a built-in threshold setting unit and a sound effect parameter configuration unit. The threshold setting unit allows users to customize multiple wind noise level thresholds, and the sound effect parameter configuration unit adjusts the frequency response using a formula. (in For the target frequency response, For the reference frequency response, The high-frequency enhancement factor is set to a value of 0.3-0.6. The low wind noise threshold is 50 dB(A). With a high wind noise threshold of 80dB(A), it pre-stores multiple sound effect modes such as high-frequency enhancement, equalization, and low-frequency enhancement. When the wind noise level is higher than 80dB(A), it will provide additional sound effects. High-frequency sound enhancement effect is activated when the wind noise level is below a certain threshold. It can be used to adjust the equalization or low-frequency enhancement effects to meet the user's personalized needs.

[0033] The external speaker module includes an audio amplification unit and a sound effects processing unit. The audio amplification unit receives volume adjustment commands from the main control module and controls the volume using an adaptive gain control formula. ( For real-time gain, This is the original audio input voltage. The output power is dynamically adjusted to achieve smooth volume adjustment without abruptness (based on the target output voltage); the sound effect processing unit receives sound effect switching instructions and adjusts the frequency response curve of the audio signal through formulas to ensure that the audio content is clearly distinguishable in windy environments, which is different from the problem of existing sound effect adjustment being lagging or ineffective.

[0034] A signal preprocessing link is set up between the audio processing module and the wind noise acquisition module to perform preprocessing operations such as noise reduction filtering and amplitude normalization on the raw signal acquired by the microphone, remove interference noise during signal transmission, and improve the accuracy of subsequent wind noise separation and identification. At the same time, the preprocessing parameters can be dynamically adjusted according to the feedback of the main control module to adapt to the signal acquisition needs in different environments. Example

[0035] Please see Figures 1-10 Furthermore, based on Example 1, the following is further obtained: the main control module establishes a wireless communication connection with an external terminal, allowing users to view the current wind noise level, volume, and sound effect status through the external terminal, while also allowing users to remotely modify the wind noise level threshold and customize the volume adjustment coefficient. and high frequency enhancement coefficient And through feedback calibration formula This forms a closed-loop control chain of "collection-identification-adjustment-feedback", improving the system's ease of use and flexibility, unlike existing systems that only support local operation and have poor interactivity.

[0036] In operation, the wind noise acquisition module first uses distributed microphones around the speaker to pick up a 360° mixed signal of environmental noise and wind noise. Signals from multiple microphones are integrated and calibrated via a synchronous link before being transmitted to a signal preprocessing link. Noise reduction filtering and amplitude normalization remove interference noise, ensuring the purity of the mixed signal. The preprocessed signal is then transmitted to the audio processing module. The built-in DSP audio algorithm calls the wind noise feature database, extracting the low-frequency characteristics and amplitude variation patterns of wind noise. By matching the correlation with database samples, wind noise is accurately separated from environmental noise. The average wind noise pressure level within a sampling time window (0.5-1s) is then calculated to determine the wind noise level (e.g., low level ≤50dB(A), medium level 50-80dB(A), high level ≥80dB(A)), and this level data is transmitted to the main control module. After receiving the wind noise level data, the main control module... The system matches pre-stored volume adjustment thresholds and sound effect parameters, calculates the target volume using adaptive gain control technology, and adjusts the volume coefficient (ranging from 1.2 to 1.5) as the wind noise level increases. Simultaneously, it dynamically switches sound effect modes based on the wind noise level: high-frequency enhancement for high-level wind noise to improve audio penetration, and equalization or low-frequency enhancement for low-level wind noise to enhance listening comfort. The main control module synchronously transmits volume adjustment and sound effect switching commands to the external speaker module. The audio amplification unit adjusts its output power for smooth volume adjustment, and the sound effect processing unit switches its frequency response curve to optimize the sound effect, ultimately ensuring clear audio content even in windy conditions. Throughout the process, the system does not cancel out wind noise, preserving the user's perception of environmental sounds and ensuring outdoor safety. Users can also remotely view the status and modify parameters via an external terminal, creating a closed-loop feedback loop to continuously optimize the adjustment effect and adapt to different scenarios and personalized needs.
