Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a method for adjusting the volume of a terminal. As shown in FIG. 1 , the method includes:

Step 101 : in the case of detecting the playback operation on the target audio data, obtain the current value of the influence factor of volume adjustment.

Wherein, with the same volume level, the user's auditory experience is different under different volume adjustment factors. Therefore, the volume adjustment factors can also be referred to as factors affecting the user's auditory experience.

Optionally, the volume adjustment influencing factor includes at least one of the following factors: whether the terminal is plugged into an earphone, the noise value of the environment where the terminal is located, and the music type of the audio data.

Wherein, with the same volume, the user hears different sounds in different situations when the terminal inputs the earphone and does not insert the earphone (ie, external playback), that is, the user's hearing experience is different.

In addition, with the same volume, when the terminal is in different environments, the sound heard by the user is different, that is, the user's hearing experience is different. Specifically, the environment in which the terminal is located may be classified into multiple levels from quiet to noisy according to the magnitude of the specific noise value.

In addition, when different types of audio data are played at the same volume level, the user's hearing experience will also be different. For example, relaxing, soothing, and rock-type music will be heard differently by users when played at the same volume level.

Based on the above-mentioned factors affecting the user's auditory experience (ie, the volume adjustment influencing factor), in the embodiment of the present invention, in the case of detecting the playback operation of the target audio data, the current value of the volume adjustment influencing factor is obtained, so that the current value of the volume adjustment influencing factor can be obtained according to the The specific values of the influencing factors for volume adjustment determine the initial volume of the playback target audio data, so as to satisfy the user's auditory experience.

Step 102: According to the current value of the volume adjustment influencing factor, adjust the volume characteristic curve obtained by pre-training to obtain an updated volume characteristic curve.

Wherein, the volume characteristic curve includes at least two discrete points corresponding to different volume values.

Optionally, the volume characteristic curve obtained by pre-training is obtained under the condition of predetermined volume adjustment influencing factors, and the predetermined volume adjustment influencing factors include: the terminal is not plugged into the earphone, and the noise value of the environment in which the terminal is located is in the first preset value. Scope, play audio data of the first type.

That is, the volume characteristic curve pre-stored in the terminal is obtained by training when the terminal is not plugged into the earphone, the noise value of the environment where the terminal is located is in the first preset range, and the audio data of the first type is played.

Specifically, for example, the volume characteristic curve pre-stored in the terminal is obtained when the terminal is not plugged into an earphone, and the terminal is in a quiet environment and plays music of a relaxed type.

Optionally, according to the current value of the volume adjustment influencing factor, adjusting the volume characteristic curve obtained by pre-training to obtain an updated volume characteristic curve, including:

According to the current value of each of the volume adjustment influence factors, determine the adjustment value corresponding to each of the volume adjustment influence factors;

Summing the adjustment values corresponding to each of the volume adjustment influencing factors to obtain the adjustment value of the volume characteristic curve;

According to the adjustment value of the volume characteristic curve, the volume value corresponding to each discrete point in the volume characteristic curve is adjusted.

That is, in the embodiment of the present invention, when adjusting the volume characteristic curve obtained by pre-training according to the current value of the volume adjustment influence factor, it is determined that the volume characteristic curve needs to be adjusted for each influence factor included in the volume adjustment influence factor. and then superimpose the adjustment values corresponding to all the influence factors included in the volume adjustment influence factors into the pre-obtained volume characteristic curve.

It can be seen from this that the embodiment of the present invention obtains the volume characteristic curve in a specific scene by pre-training, and stores it in the terminal, and then when the audio data actually needs to be played, according to the specific value of the current volume adjustment influencing factor, to update the preset volume The stored volume characteristic curve makes the volume characteristic curve conform to the current foreground.

For example, pre-training is used to obtain the volume characteristic curve of the terminal that is not plugged into the earphone and is in a quiet environment to play relaxing music, but when the terminal actually needs to play audio data, the terminal is inserted into the earphone and is in a noisy environment, and the audio data that needs to be played For the rock type, it is necessary to determine the influencing factors of each volume adjustment, the difference between the current actual playback scene and the application scene of the pre-trained volume characteristic curve, so as to obtain the corresponding adjustment of each influencing factor according to the specific difference value.

In the embodiment of the present invention, the application scenario of the volume characteristic curve is pre-determined. Then, as to the influencing factors of whether the terminal is inserted into the earphone, there are two specific situations: the terminal is inserted into the earphone and the earphone is not inserted, and this is related to whether the terminal is inserted into the earphone There are two values for the adjustment value of the pre-obtained volume characteristic curve corresponding to an influencing factor.

That is, when the volume adjustment influencing factor includes whether the terminal is plugged into an earphone, the adjustment value corresponding to each of the volume adjustment influencing factors is determined according to the current value of each of the volume adjustment influencing factors, include:

In the case where the terminal is plugged into the earphone, determine that the adjustment value corresponding to the terminal plugged into the earphone is a first preset value, and the first preset value is less than zero;

In the case that the earphone is not inserted into the terminal, it is determined that the adjustment value corresponding to the earphone not inserted into the terminal is zero.

Among them, when the terminal is plugged into the earphone, the audio data does not need a high volume to play the audio data, and the user can hear it clearly. Therefore, the application scenario of the volume characteristic curve obtained by pre-training is on the premise of When playing audio data, if the terminal is plugged into an earphone, the volume value in the volume characteristic curve obtained by pre-training needs to be reduced by a certain magnitude.

However, if the application scenario of the volume characteristic curve obtained by pre-training is that the terminal is plugged into an earphone, but the terminal is not plugged into the earphone when the audio data is actually played, the volume value in the volume characteristic curve obtained by pre-training needs to be increased by a certain magnitude .

In addition, the adjustment value for the pre-obtained volume characteristic curve corresponding to the influence factor of the noise value of the environment where the terminal is located is determined as follows:

That is, optionally, in the case where the volume adjustment influencing factor includes the noise value of the environment in which the terminal is located, determining the corresponding volume adjustment influence factor according to the current value of each of the volume adjustment influencing factors. Adjustment values, including:

In the case that the current noise value of the environment where the terminal is located is within the first preset range, determining that the adjustment value corresponding to the current noise value of the environment where the terminal is located is zero;

When the current noise value of the environment where the terminal is located is less than the lower limit value of the first preset range, determine the lower limit value and the current a first adjustment range corresponding to the difference between the noise values, and determining that the adjustment value corresponding to the current noise value of the environment where the terminal is located is a negative number whose absolute value is the first adjustment range;

When the current noise value of the environment where the terminal is located is greater than the upper limit value of the first preset range, determine the upper limit value and the current noise value according to the predetermined correspondence between the difference between the noise values and the adjustment range The second adjustment range corresponding to the difference between the noise values is determined, and the adjustment value corresponding to the current noise value of the environment in which the terminal is located is determined to be a positive number whose absolute value is the second adjustment range.

It can be seen from the above that if the actual environmental noise value when the terminal needs to play audio data is within the noise range to which the volume characteristic curve obtained by pre-training is applicable, it is not necessary to adjust the volume characteristic curve in terms of environmental noise. If the noise is quieter than the ambient noise to which the volume characteristic curve applies, it is necessary to reduce the volume value of the volume characteristic curve by a certain amount. The volume value of the volume characteristic curve is increased by a certain amount.

In addition, the adjustment value for the pre-obtained volume characteristic curve corresponding to the influence factor of the music type of the audio data is determined as follows:

That is, when the volume adjustment influencing factor includes the music type of the audio data, the adjustment value corresponding to each of the volume adjustment influencing factors is determined according to the current value of each of the volume adjustment influencing factors. ,include:

In the case that the music type of the target audio data is the second type, determine that the adjustment value corresponding to playing the audio data of the second type is a second preset value;

In the case that the music type of the target audio data is the third type, it is determined that the adjustment value corresponding to playing the audio data of the third type is a third preset value.

For example, if the volume characteristic curve obtained by pre-training is suitable for playing relaxing music, when you actually need to play soothing music, you need to increase the volume value of the volume characteristic curve by a certain amount. When you actually need to play rock-type music, you need to The volume value of the volume characteristic curve is also increased by a certain amount.

Step 103: Set the initial volume for playing the target audio data according to the updated volume characteristic curve.

Wherein, after the updated volume characteristic curve is obtained through the above steps, the initial volume of the playback target audio data can be further set.

Optionally, the at least two discrete points include a default discrete point corresponding to a default volume value; and the setting of the initial volume for playing the target audio data according to the updated volume characteristic curve includes:

The initial volume for playing the target audio data is set as the default volume value corresponding to the default discrete point.

That is, if a default discrete point is set on the volume characteristic curve obtained by pre-training, there is also a default discrete point on the updated volume characteristic curve, and the volume value of the default discrete point on the updated volume characteristic curve can be used as The initial volume at which the target audio data is played. The updated volume characteristic curve is obtained after adjustment according to the current value of the volume adjustment influencing factor. Therefore, the initial volume of the playback target audio data matches the specific situation of the volume adjustment influencing factor, thereby reducing the need for users to adjust the volume. steps to enhance the comfort of the ear.

Optionally, after the step of setting the initial volume for playing the target audio data, the method further includes:

During the playback of the target audio data, if a volume adjustment instruction input by the user is detected, after each volume adjustment instruction is received, it is determined that the updated volume characteristic curve is the same as the current playback of the target audio the first discrete point corresponding to the first volume value of the data;

determining the second volume value corresponding to the second discrete point adjacent to the first discrete point according to the volume adjustment direction indicated by the volume adjustment instruction;

Adjust the volume of playing the target audio data to the second volume value.

For example, the volume characteristic curve includes nine points from -4 to 4, the middle position point 0 represents the initial volume position (the default optimal volume), the four points from -4 to -1 are the adjustment points of the "volume minus key", 1 to 4 is the adjustment point of the "volume plus key". By default, the volume amplitude of the 0 point is initially played. When the user presses the volume up key, it will be played at the volume amplitude of the 1 point; when the user presses the volume down key, it will be played at the volume amplitude of the -1 point.

Among the discrete points included in the volume characteristic curve, the difference between the volume values corresponding to every two adjacent discrete points is different, so as to provide the user with the most suitable and fastest volume adjustment range.

It can be seen from the above that in the embodiment of the present invention, when it is detected that the terminal needs to play audio data, it triggers the extraction of various external conditions (that is, the influencing factors of volume adjustment), calculates the most suitable user volume, and jumps to the most suitable user volume position at one time. , and around the upper and lower positions of the optimal point, design for the current user volume, such as 4 to 8 non-equal-amplitude volume addition and subtraction adjustment fine areas, to provide users with the most suitable rapid volume adjustment range.

Optionally, during the playback of the target audio data, if it is detected that the user ends the volume adjustment, the third volume value currently played by the target audio data is acquired;

The volume characteristic curve is retrained according to the third volume value.

Specifically, if the third volume value is greater than the initial volume, the volume values of discrete points on the volume characteristic curve obtained by pre-training are respectively increased; if the third volume value is less than the initial volume, the Decrease the volume value of discrete points on the volume characteristic curve that will be pre-trained.

Wherein, within the preset time after receiving the volume adjustment instruction once, if the volume adjustment instruction is not received again, it is determined that the user has finished the volume adjustment, that is, the third volume value of the playback target audio data at this time satisfies the user's auditory experience .

In addition, the volume characteristic curve is optimized according to the third volume value that finally satisfies the user's auditory experience, so that when the volume is subsequently adjusted according to the volume characteristic curve, the volume that meets the user's auditory experience can be adjusted more quickly.

In addition, in the process of playing the target audio data, it is also possible to regularly detect whether the influence factor of volume adjustment changes, and the above-mentioned volume adjustment process is actively triggered when the influence factor of volume adjustment changes.
