[0081] The first signal processing unit can convert the first audio data received by the audio acquisition unit from a first sound signal into a first electrical signal in analog signal form, and can further convert the second electrical signal processed by the first power adjustment unit into a first digital signal.

[0082] The first power adjustment unit can be used to adjust the power of the input audio signal. For example, it can amplify the power of the input audio signal.

[0085] It should be known that Figure 1 The block diagram of the power intelligent adjustment device for the audio amplifier shown is only for illustration, and the number of each module shown does not limit the protection scope of the present invention.

[0086] In some possible implementation manners of the present invention, the audio acquisition unit is further configured to obtain a volume test data set through the communication unit;

[0089] The central processing unit is configured to determine reference volume data according to the feedback information of the user on the output second sound signal.

[0090] It can be understood that in order to improve the accuracy of power regulation, it is necessary to determine a reference standard. In the embodiments of the present invention, the power to be used is determined by determining the reference volume data that matches the user. First, connect to other intelligent terminals or servers through the communication unit to obtain a volume test data set. The volume test data set is classified according to different criteria, such as the type of sound output device (such as headphones, speakers, TVs, etc.), the sound effect attributes of the sound output device (such as high frequency, low frequency, amplitude, etc.), the environment where the sound output device is located (such as living room, square, meeting room, etc.), the user attributes of the sound output device (the elderly, children, hearing-impaired people, etc.), and so on. The central processing unit is used to select the first volume test data that matches the current usage scenario from the volume test data set according to preset rules (such as the correspondence between the type of sound output device and the test data or the correspondence between the environment where the sound output device is located and the test data, etc.). Then, the second signal processing unit converts the first volume test data into a fourth electrical signal, and restores the fourth electrical signal to a second sound signal and outputs it; after the user hears the output second sound signal, they can give feedback, such as feedback information through a graphical user interface or feedback information by replying with voice, etc. Among them, the feedback information can be "hearable", "can't hear clearly", etc., or it can be a selection submitted for the given options, or it can be a reply to a specific question (such as what's your name?). It can also be the information reflected by the brain wave signal. The central processing unit determines the reference volume data according to the feedback information of the user on the output second sound signal.

[0091] It should be noted that in some other embodiments of the present invention, in order to more intelligently adjust the power to achieve efficient management of the volume, the first neural network can also be trained according to historical volume data, scenario data, user data, etc. to form a reference volume model.

[0094] It can be understood that in order to make the power adjustment efficient, accurate and avoid adverse effects on components caused by excessive workload of the first power adjustment unit, in the embodiments of the present invention, a second power adjustment unit is added. The second power adjustment unit adjusts the third electrical signal by adjusting the power to change the current value size according to the reference volume data and the relationship between the volume size and the current value size, so as to achieve the purpose of adjusting the volume size to the best state.

[0095] In some possible embodiments of the present invention, a vibration monitoring unit is further included;

To solve the foregoing problems, a vibration monitoring unit is added in the embodiments of the present invention, which can, but is not limited to, monitor the operating states of the first power adjustment unit and / or the second power adjustment unit, and collect the first vibration data and / or the second vibration data generated when the two operate.

[0101] The central processing unit determines first noise data generated when the first power adjustment unit operates and / or second noise data generated when the second power adjustment unit operates according to the first vibration data and / or the second vibration data.

[0103] Finally, the central processing unit drives the first power adjustment unit and / or the second power adjustment unit to operate according to the correlation relationship model and the first noise data and / or the second noise data, so as to use the most matching power to achieve the optimal volume under the condition of meeting the hearing requirements.

[0104] In some possible embodiments of the present invention, the central processing unit is further configured to analyze the first audio data, group the first audio data according to the sound source, and assign a group identifier to each group.

[0106] Convert the grouped first audio data from a first sound signal into a first electrical signal in units of groups.

[0107] The second signal processing unit is configured to distribute the first digital signal to different signal processing channels for processing, specifically:

[0108] According to the preset correspondence between the group identifier and the signal processing channels, distribute the first digital signal to different signal processing channels for processing.

[0109] It can be understood that, in order to ensure the optimal processing effect and avoid data loss when processing audio data, in the embodiments of the present invention, the central processing unit analyzes the first audio data, groups the first audio data according to the sound source, and assigns a group identifier to each group; and converts the grouped first audio data from a first sound signal into a first electrical signal in units of groups.

[0110] Among them, the process of the second signal processing unit distributing the first digital signal to different signal processing channels for processing is specifically:

[0111] According to the preset correspondence between the group identifier and the signal processing channels, distribute the first digital signal to different signal processing channels for processing.

[0112] It should be noted that the signal processing processes and methods of different signal processing channels may be different. Through this processing method, over-processing of important signals can be avoided, and unimportant signals can be weakened or eliminated to avoid interference.

[0113] Such as Figure 2 As shown, another embodiment of the present invention provides a method for intelligent power adjustment of an audio amplifier.

[0126] The first signal processing unit can convert the first audio data received by the audio acquisition unit from a first sound signal into a first electrical signal in the form of an analog signal, and can further convert the second electrical signal obtained after being processed by the first power adjustment unit into a first digital signal.

[0127] The first power adjustment unit can be used to adjust the power of the input audio signal. For example, it can amplify the power of the input audio signal. By adjusting the gain of the audio amplifier, the amplification multiple of its power for the audio signal can be adjusted, thereby correspondingly adjusting the volume of the audio signal.
