Based on the above mobile terminal hardware structure and communication network system, the present invention provides various embodiments of the method.
Example one
The embodiment of the invention provides a control method of an intelligent power amplifier, and fig. 3 is a flow schematic diagram of the control method of the intelligent power amplifier provided by the embodiment of the invention. As shown in fig. 3, the method may include:
s301, when a playing instruction is received, detecting the current electric quantity of the battery.
In the embodiment of the invention, the terminal needs to detect the current electric quantity of the battery first and judge whether the intelligent power amplifier is suitable to be opened or not according to the current electric quantity of the battery.
It should be noted that, in the embodiment of the present invention, when the terminal detects that the play instruction of the play sound is received, the terminal automatically detects the current electric quantity of the battery.
Fig. 4 is a schematic diagram of an exemplary terminal receiving a play instruction according to an embodiment of the present invention. As shown in fig. 4, a user sends a play instruction to the terminal through a touch operation, where the sound that the user needs to play is music 3, that is, the terminal can learn that the user has performed a touch operation on the music 3 option through detection, so that the terminal receives the instruction to play music 3, determines that the music 3 is the sound to be played, and starts to detect the current battery power.
It can be understood that, in the embodiment of the present invention, the power consumption of the terminal is reduced mainly by dividing the case according to the battery power of the terminal. At first, the terminal judges whether to open intelligent power amplifier, and this is because, when terminal broadcast sound, intelligent power amplifier is not indispensable, and to the user, keeps the electric quantity at terminal sufficient, and it is most important to satisfy the user demand, consequently when the terminal is lower, closes intelligent power amplifier and can effectively reduce the terminal consumption, saves the electric quantity at terminal. Secondly, the terminal controls the working voltage of the intelligent power amplifier according to the current electric quantity of the battery, because the intelligent power amplifier in the prior art works with fixed working voltage, the fixed working voltage is generally higher, and the power consumption of the terminal is higher regardless of the state of the current electric quantity of the battery, therefore, in the embodiment of the invention, when the terminal detects that the current electric quantity of the battery can open the intelligent power amplifier, the terminal determines the corresponding working voltage of the intelligent power amplifier according to the specific size of the current electric quantity of the battery.
And S302, when the current electric quantity is larger than a preset electric quantity threshold value, opening the intelligent power amplifier.
In the embodiment of the invention, after the terminal detects the current electric quantity of the battery, whether the intelligent power amplifier is turned on or not can be judged according to the preset electric quantity threshold value.
Specifically, in the embodiment of the present invention, when the terminal detects that the current electric quantity of the battery is greater than the preset electric quantity threshold, the intelligent power amplifier is turned on, and when the terminal detects that the current electric quantity of the battery is less than or equal to the preset electric quantity threshold, the intelligent power amplifier is turned off.
It should be noted that, a preset electric quantity threshold is stored in the terminal, where the preset electric quantity threshold may be set by a user according to a daily use condition or an actual requirement of the user on the terminal, and the embodiment of the present invention is not limited specifically.
Illustratively, the preset charge threshold value stored on the terminal is 50% of the total charge of the battery. That is to say, when the terminal detects that the current electric quantity of the battery is greater than 50% of the total electric quantity of the battery, the intelligent power amplifier is opened, and when the terminal detects that the current electric quantity of the battery is less than or equal to 50% of the total electric quantity of the battery, the intelligent power amplifier is closed.
For example, the preset power threshold stored on the terminal is 50% of the total power of the battery. When the terminal detects that the current electric quantity of the battery is 35% of the total electric quantity of the battery, the terminal closes the intelligent power amplifier, and when the terminal detects that the current electric quantity of the battery is 65% of the total electric quantity of the battery, the terminal opens the intelligent power amplifier.
Fig. 5 is a schematic diagram of an exemplary terminal determining whether to turn on an intelligent power amplifier according to an embodiment of the present invention. The terminal firstly judges whether to open the intelligent power amplifier when receiving the playing instruction. If the preset electric quantity threshold value stored by the terminal is 60% of the total electric quantity of the battery, as shown in fig. 5(a), when the terminal detects that the current electric quantity of the battery is 45% of the total electric quantity of the battery, the intelligent power amplifier is automatically closed, and the display screen of the terminal can display that the current electric quantity is insufficient and the intelligent power amplifier is closed, so that a user is prompted. As shown in fig. 5(b), when the terminal detects that the current electric quantity of the battery is 70% of the total electric quantity of the battery, the intelligent power amplifier is automatically turned on, and "the current electric quantity is sufficient and the intelligent power amplifier is turned on" can be displayed on the display screen of the terminal, so as to prompt the user.
It can be understood that, in the embodiment of the present invention, the larger the preset electric quantity threshold is, the more beneficial to earlier closing the smart power amplifier is, and reducing the power consumption of the terminal.
It should be noted that, in the embodiment of the present invention, when the terminal detects that the current electric quantity of the battery is less than or equal to the preset electric quantity threshold, and after the smart power amplifier is turned off, when the terminal plays the sound, the sound to be played is directly played. That is to say, when the battery power of the terminal is low, the played sound is not processed, and the intelligent power amplifier is turned off, so that the power consumption of the terminal is reduced, and the working time of the terminal is prolonged.
S303, determining the target working voltage of the intelligent power amplifier corresponding to the current electric quantity according to the current electric quantity and the corresponding relation between the preset electric quantity and the working voltage of the intelligent power amplifier.
In the embodiment of the invention, when the terminal detects that the current electric quantity of the battery is greater than the preset electric quantity threshold value, and the intelligent power amplifier is opened, the terminal can further determine the working voltage of the intelligent power amplifier corresponding to the current electric quantity, namely the target working voltage according to the current electric quantity of the battery and the corresponding relation between the preset electric quantity and the working voltage of the intelligent power amplifier.
It should be noted that, in the implementation of the present invention, the terminal stores a corresponding relationship between a preset electric quantity and a working voltage of the smart power amplifier, and working voltages of the smart power amplifiers corresponding to different battery electric quantities are different, for example, when the electric quantity is larger, the corresponding working voltage of the smart power amplifier is larger, and when the electric quantity is smaller, the corresponding voltage of the smart power amplifier is smaller, and the specific corresponding relationship between the preset electric quantity and the working voltage of the smart power amplifier may be set by a user according to a requirement of the user, which is not limited in the embodiment of the present invention.
It can be understood that, in the corresponding relationship between the preset electric quantity and the working voltage of the intelligent power amplifier, the lower the electric quantity, the lower the working voltage of the corresponding intelligent power amplifier, which is beneficial for the terminal to reduce the power consumption generated by using the intelligent power amplifier under the condition of low battery electric quantity, and in the corresponding relationship, the lowest electric quantity is greater than the preset electric quantity threshold value.
Illustratively, the preset electric quantity threshold is 50% of the total electric quantity of the battery, and the corresponding relationship between the preset electric quantity and the working voltage of the intelligent power amplifier is as follows: the working voltage of the intelligent power amplifier corresponding to the electric quantity of 91% to 100% is a first working voltage, the working voltage of the intelligent power amplifier corresponding to the electric quantity of 81% to 90% is a second working voltage, and the working voltage of the intelligent power amplifier corresponding to the electric quantity of 51% to 80% is a third working voltage, wherein the first working voltage is greater than the second voltage, and the second working voltage is greater than the third working voltage.
For example, when the terminal detects that the current electric quantity of the battery is 92%, the working voltage of the corresponding smart power amplifier is the first working voltage, and the specific value of the first working voltage is 9V, it may be determined that the target working voltage of the smart power amplifier corresponding to the current electric quantity is 9V, and when the terminal detects that the current electric quantity of the battery is 85%, the working voltage of the corresponding smart power amplifier is the second working voltage, and the specific value of the second working voltage is 7V, it may be determined that the target working voltage of the smart power amplifier corresponding to the current electric quantity is 7V.
It should be noted that, in the embodiment of the present invention, in the corresponding relationship between the preset electric quantity stored in the terminal and the working voltage of the intelligent power amplifier, the working voltage of the intelligent power amplifier should ensure the normal operation of the intelligent power amplifier.
It can be understood that, in the embodiment of the present invention, the lower the current electric quantity of the battery is, the lower the target working voltage of the corresponding smart power amplifier is, the lower the processing degree of the smart power amplifier to the sound to be played is, and the lower the power consumption of the terminal for performing sound processing by using the smart power amplifier is.
S304, controlling the intelligent power amplifier to process the sound to be played according to a preset intelligent power amplifier algorithm to obtain the target playing sound.
In the embodiment of the invention, after the terminal determines the target working voltage of the intelligent power amplifier according to the current electric quantity of the battery and the corresponding relation between the preset electric quantity and the working voltage of the intelligent power amplifier, the terminal controls the intelligent power amplifier to perform corresponding processing according to the preset intelligent power amplifier algorithm and the characteristics of the sound to be played, so that the target playing sound is obtained.
It should be noted that, in the embodiment of the present invention, the terminal stores a preset intelligent power amplification algorithm, and the preset intelligent power amplification algorithm is used for processing the sound to be played according to the characteristic of the sound to be played.
Fig. 6 is a schematic flowchart of a process for controlling an intelligent power amplifier to obtain a target playing sound according to an embodiment of the present invention. As shown in fig. 6, the step of controlling the smart power amplifier by the terminal to obtain the target playing sound mainly includes the following steps:
s601, detecting the frequency characteristic of the sound to be played through an intelligent power amplifier.
In the embodiment of the invention, the terminal detects the frequency characteristic of the sound to be played through the intelligent power amplifier.
It should be noted that, in the embodiment of the present invention, the to-be-played sound is any audio, and the to-be-played sound may include a high frequency part and a low frequency part, that is, the terminal may control the smart power amplifier to detect the high frequency part and the low frequency part of the to-be-played sound.
It will be appreciated that the sound to be played typically contains different frequencies, for example, the sound to be played may include a low frequency portion, a mid frequency portion, and a high frequency portion. In general, the sound to be played in the middle frequency part is moderate, so the middle frequency part of the sound to be played is not frequency-processed. The high frequency part and the low frequency part have a large influence on the playing effect of the sound to be played and have a corresponding influence on the power consumption of the terminal, so that the terminal needs to perform subsequent processing on the sound to be played according to the frequency characteristic of the sound to be played.
S602, controlling an intelligent power amplifier to perform frequency processing on the sound to be played according to the frequency characteristic of the sound to be played and a preset intelligent power amplifier algorithm to obtain a target playing sound; the preset intelligent power amplification algorithm comprises a first preset intelligent power amplification algorithm and a second preset intelligent power amplification algorithm.
In the embodiment of the invention, after the terminal controls the intelligent power amplifier to detect the high-frequency part and the low-frequency part of the sound to be played, the frequency of the sound to be played is processed according to the detection result and the preset intelligent power amplifier algorithm, so that the target playing sound is obtained.
Specifically, in the embodiment of the present invention, when the terminal controls the smart power amplifier to detect that the high frequency part of the sound to be played is greater than the preset high frequency threshold, the terminal controls the smart power amplifier to reduce the frequency of the high frequency part of the sound to be played according to a first preset smart power amplifier algorithm, and suppresses the high frequency part of the sound to be played to obtain the target high frequency part; and controlling the intelligent power amplifier to update the high-frequency part of the sound to be played into a target high-frequency part to obtain the target playing sound. When the terminal controls the intelligent power amplifier to detect that the low-frequency part of the sound to be played is smaller than a preset low-frequency threshold value, controlling the intelligent power amplifier to improve the frequency of the low-frequency part of the sound to be played according to a second preset intelligent power amplifier algorithm, and compensating the low-frequency part of the sound to be played to obtain a target low-frequency part; and controlling the intelligent power amplifier to update the low-frequency part of the sound to be played into a target low-frequency part to obtain the target playing sound.
It can be understood that, in the embodiment of the present invention, when the terminal controls the smart power amplifier to detect that the high frequency part of the sound to be played is not higher than the preset high frequency threshold and that the low frequency part of the sound to be played is not lower than the preset low frequency threshold, the terminal does not need to control the smart power amplifier to process the sound to be played according to the preset smart power amplifier algorithm, and can directly perform amplification of the sound to be played.
It should be noted that, in the embodiment of the present invention, a preset high-frequency threshold and a preset low-frequency threshold are stored in the smart power amplifier of the terminal, and the specific preset high-frequency threshold and the specific preset low-frequency threshold may be specifically set according to the requirement of the user on the sound quality, which is not limited in the embodiment of the present invention.
It can be understood that, in the embodiment of the present invention, the terminal may control the smart power amplifier to perform corresponding processing on the sound to be played according to the frequency characteristic of the sound to be played.
It should be noted that, in the embodiment of the present invention, if the terminal controls the smart power amplifier to detect that the low frequency part of the sound to be played is lower than the preset low frequency threshold, the terminal then controls the smart power amplifier to increase the frequency of the low frequency part of the sound to be played according to the second preset smart power amplifier algorithm, which is beneficial to reducing the power consumption of the terminal for playing the sound.
Illustratively, the total time of the sounds to be played is 5 minutes, when the terminal detects that the sound frequency of the sounds to be played is the highest between 2 minutes 1 second and 2 minutes 20 seconds and is higher than a preset high-frequency threshold value through the intelligent power amplifier, the intelligent power amplifier is controlled to reduce the sound frequency of the sounds to be played between 2 minutes 1 second and 2 minutes 20 seconds according to a first preset intelligent power amplifier algorithm to obtain a target high-frequency part, and therefore the intelligent power amplifier is controlled to update the high-frequency part of the sounds to be played to the target high-frequency part to obtain the target played sounds. When the terminal detects that the sound frequency of the sound to be played is the lowest between 3 minutes 12 seconds and 3 minutes 40 seconds and is lower than the preset low-frequency threshold value through the intelligent power amplifier, the intelligent power amplifier is controlled to improve the sound frequency of the sound to be played between 3 minutes 12 seconds and 3 minutes 40 seconds according to a second preset intelligent power amplifier algorithm to obtain a target low-frequency part, and therefore the intelligent power amplifier is controlled to update the low-frequency part of the sound to be played into the target low-frequency part to obtain the target playing sound.
It should be noted that, in the embodiment of the present invention, if the terminal controls the smart power amplifier to detect that the high frequency part of the sound to be played is higher than the preset high frequency threshold and detect that the low frequency part of the sound to be played is lower than the preset low frequency threshold, the terminal controls the smart power amplifier to reduce the high frequency part of the sound to be played according to the first preset smart power amplifier algorithm to obtain the target high frequency part, increase the low frequency part of the sound to be played according to the second preset smart power amplifier algorithm to obtain the target low frequency part, then update the high frequency part of the sound to be played to the target high frequency part, update the low frequency part of the sound to be played to the target low frequency part, and determine the updated sound to be played as the target played sound. That is to say, the suppression of the high frequency part of the sound to be played and the compensation of the low frequency part of the sound to be played are not interfered with each other and are relatively independent, and the final target playing sound can be obtained by integrating the two after being updated.
It should be noted that, in the embodiment of the present invention, a first preset smart power amplifier algorithm and a second preset smart power amplifier algorithm are stored in a smart power amplifier of a terminal, where the first preset smart power amplifier algorithm is used to reduce the frequency of a high frequency part in a sound to be played, and the second preset smart power amplifier algorithm is used to increase the frequency of a low frequency part in the sound to be played, and the specific first preset smart power amplifier algorithm and the second preset smart power amplifier algorithm are not limited in the embodiment of the present invention.
It can be understood that, in the embodiment of the present invention, the terminal controls the smart power amplifier to process the sound to be played according to the preset smart power amplifier algorithm, so that the playing effect of the sound to be played can be improved.
S305, controlling the intelligent power amplifier to work according to the target working voltage, and amplifying the target playing sound.
In the embodiment of the invention, the terminal controls the intelligent power amplifier to process the sound to be played according to the preset intelligent power amplifier algorithm, and after the target playing sound is obtained, the intelligent terminal can be further controlled to work according to the target working voltage to amplify the target playing sound.
It should be noted that, in the embodiment of the present invention, the terminal determines the target operating voltage of the smart power amplifier according to the detected current electric quantity of the battery, and finally the terminal controls the smart power amplifier to operate according to the target operating voltage, and the power consumption of the terminal is related to the operating voltage of the smart power amplifier, that is, in the above step, the lower the target operating voltage is, the lower the power consumption of the terminal is. Therefore, the terminal controls the intelligent power amplifier to work according to the target working voltage, the power consumption of the terminal can be effectively reduced, and further, the service life of the terminal is prolonged.
The embodiment of the invention provides a control method of an intelligent power amplifier, wherein when a terminal receives a playing instruction, the current electric quantity of a battery is detected; when the current electric quantity is larger than a preset electric quantity threshold value, an intelligent power amplifier is turned on; determining a target working voltage of the intelligent power amplifier corresponding to the current electric quantity according to the current electric quantity and the corresponding relation between the preset electric quantity and the working voltage of the intelligent power amplifier; controlling an intelligent power amplifier to process the sound to be played according to a preset intelligent power amplifier algorithm to obtain a target playing sound; and controlling the intelligent power amplifier to work according to the target working voltage, and amplifying the target playing sound.
