For the sake of understanding the principle of the volume adjustment method of the present invention, the present embodiment will explain the volume adjustment method in detail by the following embodiments.
Example one
Referring to fig. 2, an embodiment of the present invention provides a method for adjusting a volume, including:
and S101, when the terminal starts to output the audio, sampling a first sampling volume value k1 of the terminal, and setting k1 as a reference volume value.
When the terminal starts to output audio in an operating state, the acquiring unit 10 acquires a first sampling volume value k1 in real time, which is a reference volume value k1 for determining whether the output audio of the terminal is changed, and thus in this step, k1 is set as the reference volume value.
Wherein, the collecting unit 10 comprises a sensor installed at the sound outlet of the terminal. The sensor may be a sound sensor, a vibration sensor, or other type of sensor capable of detecting various physical parameters of the output audio.
Therefore, the data of the first sampling volume value k1 acquired by the sensor may be sound waves or amplitudes.
And S102, sampling the second sampling volume value k2 of the terminal once every time interval in the process of outputting the audio by the terminal.
The terminal is in an operating state, and the acquisition unit 10 acquires the second detection volume value k2 in real time. The second detected volume value k2 is used to compare with the reference volume value to determine whether to enter the volume adjustment operation.
In this embodiment, the time interval between step S101 and step S102 is 3S, and the workload of the terminal can be reduced by setting the detection time interval, thereby extending the service life of the terminal.
S103, judging whether the absolute value of the (reference volume value-k 2)/reference volume value is greater than 10%; if yes, go to step S10; if not, k2 is set as the reference volume value, and then the step S102 is returned to.
In the present embodiment, in the acquisition unit 10, whether or not the absolute value of (reference volume value-k 2)/reference volume value is greater than 10% is taken as a condition for entering the volume adjustment operation.
In the daily activities of users, the situation that other objects touch the sound outlet hole carelessly often occurs, and under the situation, even if the shielding degree is small, the volume adjusting program needs to be started, the terminal is easy to have overlarge work load, and the terminal response speed is slow to a certain extent. Therefore, the aim of reducing the workload of the terminal is achieved by setting the condition of entering the volume adjustment operation.
When the variation between k2 and the reference volume value does not satisfy the condition for entering the volume adjustment operation, the acquiring unit 10 sets k2 as the reference volume value, and repeats step S102.
And S10, acquiring the volume value currently set by the terminal.
In this embodiment, the method for obtaining the volume value currently set by the terminal is as follows: the reference volume value is set to the currently set volume value by the acquisition unit 10.
And S20, acquiring the shielding volume value after the user shields the sound outlet hole of the terminal.
In this implementation, the method of obtaining the shielding volume value after the user shields the sound outlet of the terminal is as follows: the second detection volume value k2 is set as the occlusion volume value by the acquisition unit 10.
After the sound outlet hole is shielded, the output audio frequency of the terminal can be changed, a user changes the volume through shielding the sound outlet hole to obtain a shielded volume value, and the shielded volume value and the currently set volume value before change are used as the basis for adjusting the volume.
And S30, determining an adjusting coefficient according to the volume difference between the currently set volume value and the shielding volume value.
After the user blocks the sound outlet, the volume is changed from the currently set volume value to the blocking volume value.
In this embodiment, the determining unit 20 obtains the adjustment coefficient through the volume difference, and obtains the target volume value required by the user by using the adjustment coefficient as the adjustment basis, and sets the target volume value as the volume value of the terminal.
The adjustment coefficient may be obtained by:
s301, presetting a corresponding adjusting coefficient for the different volume difference values respectively.
In this step, a map for determining the adjustment coefficient is stored in advance in the determination unit 20;
the mapping relation is as follows: and under the currently set volume value, the volume difference value has a corresponding adjusting coefficient.
Specifically, the mapping relationship between the volume difference and the adjustment coefficient is used as an adjustment basis, and the volume value currently played by the terminal is adjusted to the target volume value required by the user.
As an optional implementation manner in this embodiment, the mapping relationship may be:
when the currently set volume value is 20 volumes of the terminal volume grid number and the volume difference between the currently set volume value and the occlusion volume value is 18 volumes, the adjustment coefficient is 2.
When the currently set volume value is 20 volumes of the terminal volume grid number and the volume difference between the currently set volume value and the shielding volume value is 10, the adjustment coefficient is 1.
The currently set volume value is 20 of the terminal volume grid number, and when the volume difference between the currently set volume value and the shielding volume value is 2, the adjustment coefficient is 0.5.
The manner of obtaining the adjustment coefficient may also be obtained by step S302.
S302, establishing a functional relation between the volume difference value and the adjusting coefficient, and determining the adjusting coefficient according to the functional relation.
As an optional implementation manner in this embodiment, the functional relationship is as follows:
wherein y is an adjustment coefficient, and x is a volume difference value between the currently set volume value and the shielding volume value.
In step S301 and step S302, the adjustment coefficient is in a linear function relationship with the blocking amount of the sound outlet.
And S40, obtaining a target volume value according to the adjusting coefficient and the volume value currently set by the terminal, and setting the volume value of the terminal as the target volume value.
In this embodiment, the adjusting unit 30 adjusts the volume value played by the current terminal to the target volume value required by the user according to the adjustment coefficient obtained in the above step.
S50, setting the target volume value as the reference volume value, and then returning to step S102.
In step S40, the user has adjusted the volume to the target volume value, and at this time, the capturing unit 10 sets the current target volume value as the reference volume value, and then starts with step S102 and performs a loop to achieve the purpose of volume adjustment.
