[0030] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0031] Figure 1 The present invention is a schematic diagram of an implementation environment involved in a control method for an audio power amplifier. The implementation environment includes a collection end and a service end.

[0032] See also Figure 2The present application embodiment provides a control method for an audio power amplifier, the method is applicable to an electronic device, the electronic device may be Figure 1 The server side in the implementation environment is shown.

[0033] In the following method embodiments, for ease of description, the execution subject of each step of the method is taken as an electronic device as an example for illustration, but this does not constitute a specific limitation.

[0034] like Figure 2 As shown, the method may include the following steps:

[0035] S100, obtaining corresponding environmental noise data based on a microphone installed in the speaker, obtaining characteristics of an audio signal output by the speaker, determining a corresponding music type based on the characteristics of the audio signal, and determining an output volume mode of the speaker based on the environmental noise data and the music type.

[0036] Among them, the output volume mode is pre-set in the system; a microphone is installed on the audio equipment to collect environmental noise data, and then signal processing technology (such as FFT transform) can be used to analyze the environmental noise data and extract noise characteristics. The currently playing audio signal is collected by the signal processor inside the audio, and the audio signal can be classified to identify the music type.

[0037] Adjusting the volume according to the ambient noise level can ensure that clear audio content can be heard in different noise environments. In addition, the music type is automatically identified based on the audio signal characteristics, so as to select the sound effect mode that best suits the current music type. At the same time, the volume and sound effects are automatically adjusted according to the ambient noise data and music type, and the system provides a personalized listening experience.

[0038] S110, determining whether there is a user in the room, if there is a user, obtaining distance data corresponding to the user in real time, and adjusting the output volume mode based on the distance data.

[0039] An ultrasonic sensor can be used to detect the presence of a user. When the ultrasonic sensor detects a user, distance data acquisition is initiated, and sound waves can be emitted and reflected sound waves are received, and the round-trip time is calculated to determine the distance. In the presence of a user, by acquiring the user's distance data in real time, the system can sense changes in the user's position and make corresponding adjustments to improve the user experience. When the user is away from the speaker, the volume is automatically lowered to avoid interference caused by unnecessary excessive volume; when the user is close to the speaker, the volume is automatically increased to ensure that the volume is moderate.

[0040] S120, after the audio is turned on, the audio is controlled to perform a real-time detection mode. If no audio input or human activity is detected, the audio is controlled to switch to a preset low power consumption mode. If audio input or human activity is detected, the audio is controlled to switch to a normal working mode.

[0041] Among them, whether there is audio signal input can be monitored to realize audio input detection, and user activity can be detected by motion sensor or infrared sensor. If there is neither audio input nor human activity, it is judged as idle state. When the system detects idle state, it automatically enters low power consumption mode to reduce power consumption; when the system detects audio input or user activity, it automatically switches back to normal working mode; thereby realizing automatic power consumption management, it automatically enters low power consumption mode when there is no audio input or human activity, and saves energy.

[0042] In the embodiment of the present application, the system has multiple preset output volume modes, and the user can participate in the preset output volume mode, such as Figure 3 As shown, the following steps are also performed:

[0043] S001, obtain a three-dimensional model of the room through a three-dimensional scanning device, and use acoustic simulation software to generate a corresponding sound wave distribution map.

[0044] Among them, the sound wave distribution map includes the sound wave propagation path and sound field distribution; first, use a three-dimensional scanning device to comprehensively scan the room, capture the room's geometric structure and physical characteristics, and create a detailed three-dimensional model. This three-dimensional model can reflect the actual size of the room, the location of walls, doors, windows, and other fixtures; next, use acoustic simulation software to simulate the behavior of sound waves in this environment based on the three-dimensional model, and the generated sound wave distribution map not only shows the propagation path of the sound wave from the sound source to the receiving point, but also reveals the sound pressure level at different locations (that is, the sound field distribution).

[0045] S002, in the process of adjusting the output volume mode of the speaker, obtaining the corresponding latest sound wave distribution map, and determining the corresponding sound wave distribution change based on the latest sound wave distribution map and the sound wave change map.

[0046] Among them, when the output mode of the sound system changes, the acoustic simulation is rerun to generate the latest sound wave distribution map, and then the sound wave distribution map is compared with the latest sound wave distribution map to identify changes in the sound wave distribution, such as the sound becoming stronger or weaker in certain areas.

[0047] S003, displaying the sound wave distribution change to the user, obtaining the latest output volume mode set by the user and storing it.

[0048] The changes in sound wave distribution are presented to the user in the form of a graphical interface, such as using color coding to indicate changes in sound pressure level. A user interface is provided to allow the user to adjust the output volume mode, and the sound wave distribution diagram is updated in real time after each adjustment. The optimal output mode selected by the user is stored so that it can be automatically loaded the next time it is used.

[0049] By executing steps S001 to S003, the overall sound quality in the room can be improved by precisely controlling the distribution of sound waves and reducing unnecessary reflections and standing waves. Visual tools can be used to help identify acoustic problem areas in the room, and users can adjust the audio system according to their preferences. The system can remember the user's preferred settings and automatically apply them to future usage scenarios.

[0050] In addition, when a user is detected indoors, the following steps are performed:

[0051] S111, obtaining biometric data corresponding to the user, and identifying and determining the corresponding target user based on the biometric data.

[0052] Among them, when the user approaches the audio system or actively triggers recognition, the device collects the user's biometric data. By using biometric recognition devices (such as fingerprint readers, facial recognition cameras, iris scanners, etc.) to capture the user's biometric information, the system will compare the collected biometric information with the biometric information of registered users in the database to find the record with the highest match.

[0053] Biometric recognition technology can ensure that only authorized users can access the audio system, increasing security; it can also quickly identify specific target users, ensuring that the audio system can automatically adjust to the settings suitable for the user based on different user identities.

[0054] S112: Retrieving corresponding target audio settings from a pre-stored user preference database based on the target user.

[0055] Among them, after the target user is successfully identified, the system queries the audio setting information in the target user's personal preference database, and can retrieve the user's audio preference settings from the server or local database through the identified user ID, and enable the audio system to automatically adapt to the auditory preferences of different users without manual adjustment each time, thereby improving convenience.

[0056] S113, switching the output volume mode corresponding to the sound system based on the target sound system settings.

[0057] Among them, the audio settings obtained from the database are applied to the current audio equipment through the control interface of the audio system (which may be a hardware button, software interface or wireless communication protocol). After receiving the new setting instructions, the audio system adjusts the output volume mode to the specified state; thus ensuring that each user can enjoy the sound effects they are accustomed to, thereby enhancing user satisfaction.

[0058] By executing steps S111 to S113, the user identity is confirmed using biometric recognition technology, and the audio settings are automatically adjusted according to the user's preferences. This not only improves the personalized service level of the audio system, but also strengthens the security of the system.

[0059] At the same time, the system will also perform intelligent control based on the distance between the user and the speaker. In the process of adjusting the output volume mode based on distance data, the specific implementation process includes:

[0060] S114, obtaining distance data between the user and the speaker through an ultrasonic sensor.

[0061] The method for obtaining the distance data has been described above and will not be elaborated here.

[0062] S115, retrieve a preset distance division interval set, match the distance data with the distance division interval set, and determine a corresponding target distance division interval.

[0063] Among them, a set of distance division intervals are pre-defined, for example: 0 to 1 meter, 1 to 2 meters, 2 to 3 meters, 3 to 4 meters, and above 4 meters, and these intervals are stored in the system. Through the preset distance division intervals, the system can quickly find the interval to which the distance data belongs, and can adjust the interval definition according to actual conditions to adapt to different usage scenarios and needs.

[0064] The collected distance data is compared with the preset distance division intervals, and the target distance division interval of the user is determined according to the matching results. The interval to which the distance data belongs is found, which can ensure that the distance data can be accurately mapped to the corresponding interval, thereby providing an accurate basis for subsequent volume adjustment.

[0065] S116, determining corresponding target volume interval data based on the target distance division interval and a preset mapping relationship, determining corresponding target volume data by a linear interpolation method, and controlling the output volume of the audio system based on the target volume data.

[0066] Among them, the mapping relationship is the mapping relationship between the distance division interval and the volume interval data. It should be pointed out here that a mapping table is set in advance to define the volume interval data corresponding to each distance division interval, for example: 0 to 1 meter: the volume is set to 20%; 1 to 2 meters: the volume is set to 40%; 2 to 3 meters: the volume is set to 60%; 3 to 4 meters: the volume is set to 80%; above 4 meters: the volume is set to 100%.

[0067] At the same time, by dividing the intervals according to the target distance, the system can automatically determine the appropriate volume interval through mapping relationships without the need for manual settings by the user. Different mapping relationships can also be pre-set according to the auditory needs of different users to provide personalized volume adjustments.

[0068] If the actual distance between the user and the speaker falls between the two intervals, a linear interpolation method is used to calculate the target volume data. For example, if the user is 1.5 meters away, the system will calculate the target volume data based on the linear relationship between the 1-2 meter interval (40%) and the 2-3 meter interval (60%): , for example, when the user distance is 1.5 meters, the calculation formula is: ,Through the linear interpolation method, the volume can be accurately adjusted through the ,interpolation method even if the user distance changes slightly, ensuring a smooth volume adjustment ,process and avoiding the discomfort caused by abrupt changes.

[0069] Finally, the system monitors the user's distance in real time and dynamically adjusts the volume according to the change in distance. By adjusting the volume in real time, the system can better adapt to the user's movement, thereby providing a more comfortable and personalized audio experience and improving the intelligence level of the system.

[0070] In the embodiments of the present application, Figure 4 As shown, the method also includes:

[0071] S121, obtaining common time periods corresponding to when the audio is turned on, and recording the user's playing preferences in the common time periods.

[0072] There are multiple commonly used time periods, and the playback preferences include the types of music most frequently played by different users and the corresponding sound effect settings.

[0073] Record the timestamp when the speaker is turned on, and count the frequency of users turning on the speaker in different time periods. Based on the statistical data, define the user's "common time periods", such as 6:00-8:00 in the morning, 7:00-10:00 in the evening, etc., and record the types of music that users play most frequently and the corresponding sound effect settings during the common time periods. By recording the user's speaker usage in different time periods, you can understand the user's habits and preferences.

[0074] S122, associating the commonly used time periods with the playback preferences, and using the associated commonly used time periods and the playback preferences as training sets for a prediction model, and determining a corresponding prediction model.

[0075] Among them, commonly used time periods are paired with playback preferences to form a training data set, and then a suitable machine learning model, such as a neural network, is selected. The model is trained using the organized training data set to learn the correlation between commonly used time periods and playback preferences. The accuracy and generalization ability of the model are then evaluated through methods such as cross-validation to ensure that the model can accurately predict future usage patterns.

[0076] By training the model, the system can predict the user's usage patterns in a certain period of time in the future, and based on the prediction results, the system can automatically adjust the settings of the speaker.

[0077] S123, obtaining a corresponding time series, inputting the time series into a prediction model, obtaining a corresponding predicted future usage pattern of the user, and controlling the audio system based on the future usage pattern.

[0078] By obtaining the current time in real time and using it as an input time series, and inputting the current time into the trained prediction model, the system can predict the user's future usage pattern in real time based on the current time. The future usage pattern includes the type of music the user may play and the sound effect settings; based on the predicted future usage pattern, the system automatically adjusts the volume of the speaker, sound effect settings, etc.

[0079] By executing steps S121 to S123, the system can predict future usage patterns based on the user's playback preferences during common time periods and automatically adjust the audio settings accordingly; this not only improves the intelligence level of the audio system, but also significantly improves the user experience, ensuring that users can get the best hearing effects in different time periods.

[0080] After the speaker is used for the first time, follow these steps:

[0081] S124 obtains the device parameters of the audio system in real time through built-in sensors.

[0082] Various built-in sensors, such as temperature sensors, current sensors, vibration sensors, etc., are installed in audio equipment to monitor the operating status of the equipment. These sensors collect the operating parameters of the audio equipment in real time, such as temperature, current, voltage, vibration, etc., and then transmit the collected equipment parameters to the central processing unit or cloud server for processing via wireless or wired means.

[0083] S125, matching the device parameters with the preset threshold intervals, and if they do not match, when it is determined that there is a potential fault, sending a warning message to the user or technician.

[0084] Among them, a series of threshold ranges are pre-set according to the technical specifications of the audio equipment and the manufacturer's recommended values. For example, the upper temperature limit is set to 50°C, the upper current limit is set to 2A, etc.; the device parameters collected in real time are compared with the pre-set threshold ranges to check whether there are any situations beyond the normal range.

[0085] When device parameters exceed the preset threshold range, the system determines that there is a potential fault, generates an early warning message, and sends it to the user or technical support personnel through various means (such as SMS, email, application notification, etc.). The early warning message should include the specific device parameter abnormality, possible cause analysis, and recommended countermeasures.

[0086] During the data collection stage, the temperature sensor: monitors the temperature inside the audio equipment in real time; the current sensor: monitors the working current of the audio equipment in real time; the vibration sensor: monitors the vibration of the audio equipment in real time.

[0087] In the matching and judgment stage, the temperature threshold: set the normal operating temperature range to 20°C to 50°C; the current threshold: set the normal operating current range to 0A to 2A; the vibration threshold: set the normal operating vibration range to 0mm / s to 10mm / s.

[0088] During the execution of the warning information sending stage: if the temperature is detected to be over 50°C, a warning message is sent; if the current is detected to be over 2A, a warning message is sent; abnormal vibration: if the vibration is detected to be over 10mm / s, a warning message is sent.

[0089] The built-in sensors can obtain the operating parameters of the audio equipment in real time to ensure that the system can detect abnormal situations in time. Through the pre-set threshold range, the system can automatically determine whether the equipment parameters are out of the normal range and realize standardized monitoring. When potential faults are found, the system can promptly send early warning information to users or technicians to help take quick measures to avoid greater losses.
