[0002] With the wide application of wireless earphones in the fields of personal audio entertainment, sports monitoring, etc., related technologies have been continuously developed and improved. Wireless earphones usually transmit audio signals from a signal source (such as a smartphone, a tablet computer, an audio device, etc.) to the earphones through wireless communication protocols such as Bluetooth or Wi-Fi to achieve audio playback. However, although wireless earphones have made significant progress in providing a convenient and comfortable user experience, there are still some deficiencies in the existing technologies, which limit the performance of wireless earphones in some complex environments.

[0003] Currently, the existing wireless earphones have obvious deficiencies in dealing with complex environmental noise. The noise filtering technologies of most earphones are still relatively basic. These technologies have weak adaptability to dynamically changing environmental noise and often rely on fixed signal transmission modes and simple spectrum management, without sufficient intelligent optimization mechanisms to cope with complex signal environments, resulting in a decline in signal quality and affecting the audio experience. When multiple earphones are used simultaneously, especially in a multi-person scenario such as between a tour guide and tourists, the surrounding noise may interfere with the audio signal transmission of the earphones, resulting in, for example, a tour guide's explanation or music playback, making it impossible for users to clearly hear the audio content.

[0019] By providing a method for enhancing the signal of wireless earphones, this application solves the technical problem in the prior art that due to the basic noise filtering technology, simple spectrum management, and lack of intelligent optimization mechanism, the noise adaptation ability of wireless earphones in complex environments is insufficient, which further affects the signal transmission quality and audio clarity, and further affects the user experience. It realizes the intelligent perception and dynamic optimization management of complex environmental noise, and achieves the technical effect of providing stable and clear audio signal transmission in a dynamically changing environment, significantly improving the audio experience and user satisfaction.

[0020] Next, the technical solutions in this application will be described clearly and completely with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments of this application. It should be understood that this application is not limited by the example embodiments described here. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this application. Additionally, it should be noted that for the sake of description, only the parts related to this application are shown in the accompanying drawings rather than all of them.

[0021] Please refer to the attached Figure 1 drawings. This application provides a method for enhancing the signal of wireless earphones, which specifically includes the following steps:

[0022] Step 1: Based on the target sensor built in the target wireless earphone, the environment is monitored in real time to obtain environmental audio data.

[0023] Specifically, the target wireless earphone is the wireless earphone to be enhanced in signal. For example, multiple earphones of the same type as the target wireless earphone and the target wireless earphone may be connected to the signal source at the same time, which may be used in the case where multiple wireless earphones are connected to the same signal transmitter. The target sensor built in the target wireless earphone can obtain accurate environmental audio data by monitoring the environment around the user in real time. The target sensor includes an accelerometer, a gyroscope, etc., and can sense the surrounding sounds, vibrations, and the user's movement state. Through the data collected by the target sensor, the target wireless earphone can obtain environmental audio data in real time, so as to make a quick response to different environments, ensure that the target wireless earphone can adapt to environmental noise changes, and provide a clearer and more comfortable audio experience.

[0024] Step 2: Conduct a transmission impact assessment on the interference source information obtained by classifying the environmental audio data to obtain the interference source transmission impact.

[0025] Specifically, by analyzing the ambient audio signals collected by the target wireless earphones, different types of noises are identified, such as traffic noise, human voices, or mechanical noise, etc. The process of noise classification involves analyzing features of the audio signals such as frequency, amplitude, duration, etc., so as to determine the types of noise sources. After that, the interference source information is used for transmission impact assessment to evaluate the impact on the audio transmission quality, that is, to analyze whether the noise will interfere with the clarity or stability of the earphone audio signals. For example, traffic noise may cause the audio signals received by the earphones to be blurred, while the conversations of a crowd may interfere with the voice output of the tour guide. By evaluating different interference sources, the specific impact of each interference source on the earphone transmission is calculated, so as to judge the degree of impact of the noise on the audio quality.

[0026] Step 3: Based on the transmission impact of the interference source, optimize the frequency band of the target wireless earphones to obtain a target signal.

[0027] Specifically, the target wireless earphones will adjust the frequency band of signal transmission according to the interference source situation in the surrounding environment to ensure a more stable and clear audio experience. For example, when the target wireless earphones detect that multiple electronic devices (such as other wireless earphones, mobile phones, routers, etc.) in the vicinity are using the same frequency band, the devices will interfere with each other, resulting in a decline in signal quality. To avoid interference, the target wireless earphones will automatically switch to a frequency band with less interference and select a relatively idle frequency range to improve the signal transmission quality. In this frequency band, interference sources can be effectively avoided, thus ensuring the clear transmission of the target signal and avoiding problems such as disconnection or decline in audio quality.

[0028] Step 4: Perform signal transmission of the target wireless earphones according to the target signal.

[0029] Specifically, the audio signals sent from a signal source (such as a mobile phone or other audio device) are transmitted to the target wireless earphones through wireless technology (such as Bluetooth). After receiving the signals, the target wireless earphones will convert them into sound and play them out so that the target user can hear. Among them, the quality of signal transmission is affected by factors such as distance, interference, and the receiving ability of the earphones. If the target signal is strong and the transmission distance is short, the target wireless earphones can clearly receive the audio and play it; but if the signal is weak or there are interference sources in the environment, the receiving quality of the target wireless earphones may decline, resulting in sound stuttering or interruption. To optimize the transmission quality, the target wireless earphones will automatically adjust the transmission frequency band or signal power to ensure that the target signal can be transmitted smoothly and played clearly. Therefore, through the stable transmission of the signal, it is ensured that the target signal can reach the target earphones smoothly without interference, providing a high-quality auditory experience.

[0030] The described method for enhancing the signal of wireless earphones can achieve intelligent perception and dynamic optimization management of complex environmental noise, and achieve the technical effect of providing stable and clear audio signal transmission in a dynamically changing environment, significantly improving the audio experience and user satisfaction.

[0031] Furthermore, as Figure 2 shown, this application further includes: performing adaptive spectrum management on the target wireless earphone according to the influence of the interference source transmission to obtain a target channel; if the target signal of the target channel does not meet the transmission threshold, performing a neighborhood search of the neighborhood threshold on the target wireless earphone to determine neighborhood wireless earphones; performing adaptive link optimization according to the neighborhood wireless earphones to obtain a target transmission link; and performing signal transmission according to the target transmission link to obtain the target signal.

[0032] Specifically, after the target wireless earphone evaluates in real time the influence of interference sources (such as traffic noise, electromagnetic interference, etc.) in the environment on audio transmission, it automatically selects a suitable frequency band for signal transmission to obtain a target channel, enabling the target wireless earphone to avoid interference sources and select the frequency band with the least interference to ensure audio quality.

[0033] After selecting the frequency band, the signal quality of this frequency band is checked through the target wireless earphone. If the signal quality at this time is lower than the preset transmission standard (such as the signal strength is lower than the set threshold), search for other headphone devices within the range around the target wireless earphone, that is, the same type of wireless earphones. The signals of the neighborhood wireless earphones can help the target wireless earphone enhance the signal and ensure the stable transmission of audio. For example, if the target earphone cannot connect to its own channel, it may look for other devices (such as other users' earphones) as a way to relay or bridge the signal.

[0034] The target wireless earphone will dynamically optimize the connection path with the neighborhood earphones according to the signal quality of the found neighborhood earphones to ensure stable signal transmission, including adjusting the transmission power, adjusting the transmission mode (such as frequency hopping or other wireless protocols), etc. For example, the target wireless earphone may choose to establish a connection with a neighborhood wireless earphone with higher signal quality, or enhance signal stability through a multi-earphone collaborative transmission mode.

[0035] After link optimization, the target wireless earphone performs actual signal transmission through the determined optimal transmission path and ensures the clarity and stability of the audio signal, ensuring that the target wireless earphone can successfully receive high-quality audio signals.

[0036] By evaluating the influence of interference sources in real time and selecting the optimal frequency band for transmission, it is ensured that the target wireless earphone can always receive high-quality audio signals, guaranteeing the smoothness of the user experience and the clarity of the sound quality.

[0037] Furthermore, this application also includes: evaluating the filling degree of the real-time channel obtained based on the target wireless earphone to obtain the first filling degree; evaluating the filling degree of the pre-jump channel obtained by performing channel pre-jump according to the target wireless earphone to obtain the second filling degree; and selecting the real-time channel and the pre-jump channel according to the first filling degree and the second filling degree to obtain the target channel.

[0038] Specifically, in the current signal channel, the target wireless earphone analyzes factors such as the spectrum utilization and signal interference of the channel to evaluate the idle degree of the channel, and then obtains the filling degree of the channel, that is, the congestion degree of signal transmission, as the first filling degree. Among them, the larger the signal transmission capacity of the channel, the higher the filling degree, which may affect the signal quality, and vice versa.

[0039] After the target wireless earphone performs channel pre-jump, it evaluates the new channel to obtain the filling degree of the channel, which is the second filling degree. Pre-jump means that when the earphone detects that the signal quality of the current channel is poor, it switches to another channel in advance for testing and evaluates the idle degree of the channel, which helps the earphone to switch to a more suitable channel in time when the signal is unstable or there is more interference.

[0040] After analyzing the filling degrees of the real-time channel and the pre-jump channel, the target wireless earphone will select the channel with a lower filling degree and less interference as the target channel to ensure stable signal transmission.

[0041] By evaluating the filling degrees of the current signal channel and the pre-jump channel of the target wireless earphone, it is ensured that the earphone can select the best channel for audio signal transmission. The target wireless earphone automatically switches to a channel with a lower filling degree to ensure signal stability and clear sound quality.

[0042] Furthermore, this application also includes: extracting the first wireless earphone that transmits with the target wireless earphone from the neighboring wireless earphones according to the transmission distance; and relaying and forwarding the target source signal through the first wireless earphone to obtain the target transmission link.

[0043] Specifically, by measuring the distance between the target wireless earphone and other earphones, the earphone closest to the target wireless earphone is selected as the first wireless earphone to ensure the most stable and reliable signal transmission between the first wireless earphone and the target earphone.

[0044] The target source signal is the signal source that emits audio signals to the target wireless earphones. The selected first wireless earphone will perform the function of signal relay. The first wireless earphone receives the audio information sent by the target source signal, forwards it to the target wireless earphone, and forwards it to other earphones. Through the relay and forwarding mechanism, the stability of the target wireless earphone in signal transmission can be ensured, and signal loss or quality degradation caused by obstacles or excessive distance can be avoided.

[0045] By determining the neighboring wireless earphone closest to the target wireless earphone as the signal relay earphone, and then relaying and forwarding the signal through this earphone, it is ensured that the signal can be stably and smoothly transmitted to the target wireless, avoiding signal attenuation or interference and improving the overall audio experience.

[0046] Furthermore, this application also includes: extracting and scoring the neighboring wireless earphones according to the transmission distance to obtain neighboring earphone scores; predicting obstacles according to the transmission quality between the neighboring wireless earphones and the target wireless earphone, and extracting and scoring according to the obstacle prediction result to obtain obstacle-free earphone scores; fusing the neighboring earphone scores and the obstacle-free earphone scores, and obtaining the first wireless earphone from the neighboring wireless earphones according to the fusion score.

[0047] Specifically, scores are assigned to each neighboring wireless earphone according to the distance between the target wireless earphone and the surrounding neighboring earphones. Among them, the closer the distance, the better the quality of the transmitted signal, and the higher the score, and vice versa. Through the physical distance between the earphones, neighboring wireless earphones closer to the target wireless earphone are preferentially selected as potential relay or forwarding earphones.

[0048] When evaluating neighboring wireless earphones, it is also necessary to judge whether there are obstacles between them. For example, walls, furniture or other objects may affect the transmission quality of the signal. According to the obstacle prediction result, an obstacle-free earphone score is assigned to each neighboring wireless earphone. Among them, the fewer obstacles on the transmission path, the higher the score of the neighboring wireless earphone, and vice versa.

[0049] Taking into account both the distance between the earphones and the obstacle situation of signal transmission, by weighted fusion of the neighboring earphone scores and the obstacle-free earphone scores, a fusion score is obtained, so as to select the most suitable earphone as the signal relay. Among them, the higher the fusion score, the corresponding neighboring wireless earphone will be preferentially selected, and vice versa.

[0050] By comprehensively considering the influencing factors of the physical distance and transmission quality of the earphones (such as the influence of obstacles), a score is assigned to each neighboring earphone, and the most suitable earphone is selected as the signal relay through the fusion score, so that the best earphone can be intelligently selected in a dynamic environment, ensuring signal stability and transmission quality, and optimizing the performance and user experience of the target wireless earphone.

[0051] Furthermore, this application also includes: setting a signal sudden drop threshold; if the transmission signal between the neighboring wireless earphone and the target wireless earphone meets the signal sudden drop threshold, obtaining a low transmission quality; obtaining an obstacle presence result based on the low transmission quality to complete obstacle pre-judgment.

[0052] Specifically, in the target wireless earphone, in order to monitor the signal quality, a standard value is set, which is called the signal sudden drop threshold. The signal sudden drop threshold is used to judge whether the signal has a significant attenuation. When the signal strength suddenly drops and is lower than the set threshold, it can be considered that the signal quality is interfered.

[0053] When the transmission signal between the neighboring wireless earphone and the target wireless earphone significantly drops and reaches the set signal sudden drop threshold, it is determined that the quality of the signal transmission becomes poor, that is, a low transmission quality occurs, so as to ensure that the system can make corresponding adjustments according to the attenuation of the signal.

[0054] After the signal quality drops to the set threshold range, it is speculated that there may be obstacles affecting the signal transmission. By identifying the low transmission quality and combining the data of other sensors, the pre-judgment of obstacles is carried out. The obstacles may be walls, furniture or other devices that hinder the smooth propagation of the signal. Therefore, when the signal quality is low, it is inferred that there may be obstacles and corresponding measures are taken for optimization.

[0055] By setting the signal sudden drop threshold, the signal quality between the earphones is monitored. When the signal strength significantly drops and meets the set threshold, it is judged as a low transmission quality, and further analysis is carried out to determine whether there are obstacles, completing the obstacle pre-judgment, identifying and responding to signal attenuation and interference, so as to ensure the communication quality between the earphones and improve the user experience.

[0056] Furthermore, this application also includes: monitoring the position and movement state of the target user through the target wireless earphone to obtain the target user state; constructing an environmental prediction model, inputting the target user state into the environmental prediction model for environmental audio prediction to obtain the predicted environmental audio; comparing and verifying the predicted environmental audio and the environmental audio data. If the comparison result meets the comparison threshold, the volume of the predicted environmental audio is enhanced and used as the environmental audio data.

[0057] Specifically, the target wireless earphone monitors the position and movement state of the target user through built-in sensors (such as accelerometers, gyroscopes, etc.) to obtain the current state of the target user. The built-in sensors can real-time sense the movement trajectory of the user, for example, detecting whether the user is walking, standing or sitting, so as to obtain accurate user activity information. Through the target user state, the target wireless earphone can adapt to the real-time needs of the user, such as improving the audio transmission quality when walking or reducing power consumption when stationary.

[0058] Next, the target user is the user who holds the target wireless earphones. By analyzing the motion state of the target user and environmental changes, an environmental prediction model is constructed to predict the audio situation in the environment where the user is located. For example, when the target user is walking, the environmental prediction model predicts the possible noises in the surrounding environment, such as traffic noise or the conversations of the crowd, thereby providing a basis for optimizing the audio for the earphones.

[0059] Then, the predicted environmental audio is compared and verified with the actual environmental audio data to ensure the accuracy of the environmental prediction model and to verify whether the audio in the actual environment conforms to the prediction. If the comparison result meets the set comparison threshold, it means that the difference between the predicted environmental audio and the actual environmental audio is within an acceptable range, and the volume of the predicted audio is enhanced to improve the clarity and audibility of the audio. For example, when the surrounding environmental noise is large, the earphone volume is automatically increased to ensure that the target user can clearly hear the explanation of the tour guide or other important audio content, and the enhanced audio will continue to be transmitted and played as environmental audio data.

[0060] By monitoring the motion state of the user and environmental changes in real time, constructing and verifying the environmental audio prediction model, and then adjusting the volume output according to the prediction result, a more stable and clear audio experience can be provided in a dynamic environment to provide a more comfortable auditory experience.

[0061] Furthermore, this application also includes: selecting a power consumption mode according to the target user state to obtain a power consumption mode; and performing intelligent sleep and wake-up of the target wireless earphones according to the power consumption mode.

[0062] Specifically, an appropriate power consumption mode is selected according to the activity state of the target user. Among them, when the user is in a stationary or resting state, the earphone can be switched to a low power consumption mode to extend the battery life; while when the user is in a motion state or is using the earphone, a higher power consumption mode may be selected to provide higher performance and a clearer audio experience. For example, when the user is sitting quietly, the earphone can reduce the power consumption to the lowest level, and may only require a small amount of power to maintain the standby state of the earphone. On the contrary, when in motion or listening to an explanation, the earphone will select a high power consumption mode to ensure the stability and clarity of audio transmission.

[0063] The target wireless earphones intelligently enter the sleep state or wake up according to the selected power consumption mode. Among them, in the low power consumption mode, they can enter the sleep state when there is no user operation for a long time, reducing energy consumption and thus extending the battery usage time; and when the user wears the earphones again or starts using them, the earphones will restart through the intelligent wake-up mechanism and return to the working state. For example, if the user does not use the earphones for a long time, the earphones may enter the sleep state until the user wears them or triggers an action (such as touching the earphones), and then the earphones will be restored to the normal working state through intelligent wake-up.

[0064] Select different power consumption modes according to the user's state to optimize the battery usage time. When the user is stationary or resting, the earphones will switch to the low power consumption mode to save power; while when higher performance is required, the earphones will enter the high power consumption mode. In addition, through the intelligent sleep and wake-up mechanism, the earphones can automatically sleep when not in use by the user and quickly resume the working state when needed, thus further extending the battery life and enhancing the user experience.

[0065] In summary, a wireless earphone signal enhancement method provided by this application has the following technical effects: by continuously monitoring the environment based on the target sensor built in the target wireless earphone to obtain environmental audio data; conducting a transmission impact assessment on the interference source information obtained by classifying the noise in the environmental audio data to obtain the interference source transmission impact; optimizing the frequency band of the target wireless earphone based on the interference source transmission impact to obtain the target signal; and performing signal transmission of the target wireless earphone according to the target signal. That is to say, by realizing the intelligent perception and dynamic optimization management of complex environmental noise, the technical effect of providing stable and clear audio signal transmission in a dynamically changing environment is achieved, significantly improving the audio experience and user satisfaction.
