Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be appreciated that reference throughout this specification to "one embodiment" or "an embodiment" means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, the appearances of the phrases "in one embodiment" or "in an embodiment" in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
In various embodiments of the present invention, it should be understood that the sequence numbers of the following processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
Referring to fig. 1, an embodiment of the present invention provides an audio playing method, which is applied to a terminal device, and the method includes:
In the embodiment of the invention, as the file of the playing content is old, the terminal equipment can play the audio and video data timely, and even if the volume of the playing component is adjusted to be maximum, the volume output by the loudspeaker in the terminal equipment can still not meet the actual requirement of a user. Specifically, the volume state is used for describing whether the actual playing effect of the audio file played by the terminal device reaches the expected effect, and specifically, whether the actual playing effect of the current terminal device reaches the expected effect can be determined according to the speaker input audio energy of the terminal device when the terminal device plays the normal audio file and the speaker input audio energy of the terminal device when the terminal device plays the target audio file. The volume state may be the energy of the sound output by the speaker when the terminal device plays the audio content. It should be noted that, when determining whether the actual playing effect achieves the expected effect, the audio energy of the ambient noise collected by the microphone may be further integrated, so that the determined volume state may take into account the environmental factors of the terminal device.
It should be noted that the current playing content may be a playing content obtained by playing an audio file, a content obtained by playing a video file, or a content obtained by playing another file having audio data.
And 102, receiving a first input of a user if the volume component of the terminal equipment has been adjusted to the maximum volume under the condition that the volume state is the abnormal volume state.
In the embodiment of the invention, when the output effect of the speaker does not meet the user requirement when the audio and video data is played by the terminal device, the player may output audio energy lower than expected after reading due to the fact that the file of the audio and video data is too long, so that the input of the speaker is too small. Therefore, when the volume terminal is judged, whether the playing state of the playing target audio file is the abnormal volume state can be determined by comparing the speaker input audio energy when the normal audio file is played with the speaker input audio energy when the target audio file is played, or whether the playing state of the playing target audio file is the abnormal volume state can be determined by comparing the speaker input audio energy when the target audio file is played with the audio energy of the environmental noise collected by a microphone on the terminal equipment.
In practical application, if a user considers that the playing volume of the terminal device does not meet the self requirement, the volume component of the terminal device is adjusted to adjust the volume, but if the volume component is adjusted to the maximum value, the self requirement is not met, the first input of the user can be received through the terminal device, and therefore the intelligent multi-stage function for volume compensation in the terminal device is activated. Specifically, the intelligent multi-stage function may specifically include an equal interval up-regulation mode and an adaptive up-regulation mode. When the user performs the first input in the equal interval up-regulation mode, the volume component of the terminal equipment can be further subjected to fixed increment up-regulation until the self requirement is met. When the user performs the first input in the adaptive up-regulation mode, the user can further perform dynamic incremental up-regulation on the volume component of the terminal device according to the audio energy of the ambient noise. It is to be understood that the first input may be in an equal-interval up-regulation mode, or in an adaptive up-regulation mode, and is adapted to different up-regulation modes, where the actually adjusted volume values of the first input may have differences, the equal-interval up-regulation mode is adapted to the user to regulate the volume when the ambient noise is small, and the adaptive up-regulation mode is adapted to the user to quickly regulate the volume to the volume adapted to the ambient noise when the ambient noise is large.
It should be noted that, when the volume state is the volume normal state, the normal volume increase or volume decrease input of the user is received, and the power of the speaker of the control terminal device is correspondingly increased or decreased.
And 103, responding to the first input, and amplifying the audio energy of the sound signal corresponding to the playing content.
In the embodiment of the invention, a user can generate the first input by performing preset operation on the volume component, and the terminal device can add the gain corresponding to the first input to the sound signal corresponding to the playing content according to the first input of the user, so that the audio energy value of the sound information input to the loudspeaker is further increased on the basis of the original maximum volume value of the volume component.
In the embodiment of the invention, the terminal device inputs the audio energy to the loudspeaker according to the sound signal for amplifying the audio energy aiming at the playing content according to the first input of the user, so that the loudspeaker outputs the sound with larger volume to meet the volume requirement of the user.
In the embodiment of the invention, when the volume state of the current playing content is determined to be in the abnormal volume state and the volume component is adjusted to the maximum volume, the audio energy of the sound signal of the file with the abnormal audio content can be amplified and then input into the loudspeaker, so that the intensity of the sound signal input into the loudspeaker is increased, the sound played by the loudspeaker is increased, the sound heard by a user is increased, and the requirement of the user for the larger output volume of the terminal equipment is met.
Referring to fig. 2, an embodiment of the present invention provides another audio playing method, which is applied to a terminal device, and the method includes:
In the embodiment of the present invention, if the terminal device is equipped with a microphone, the ambient noise of the environment around the terminal device may be collected by the microphone for a preset time period, for example, for 1s or other time periods, so as to analyze the audio energy mean of the collected noise audio from the collected sound to obtain the first energy value E1 of the noise audio.
In step 202, a second energy value of the sound signal input to the speaker is obtained.
In the embodiment of the present invention, when the terminal device collects the environmental noise, the audio energy mean value of the sound information input to the speaker of the terminal device is obtained, so as to obtain the second energy value E2, it should be noted that the noise audio and the sound signal are collected at the same time, and the collection time periods are the same, so as to ensure the accuracy of the subsequent processing.
In the embodiment of the present invention, the first threshold T1 may be obtained through experiments, for example, playing a sample audio file according to different input audio energies under different noisy audio energy environments by using a terminal device, determining, by a user, the input audio energy when audio content of the sample audio file can be clearly identified according to an actual auditory effect, and thus determining the T1 according to a ratio of current noisy audio energy of the environment to current input audio energy. If the ratio of the first energy value E1 to the second energy value E2 of the terminal device in the current environment is larger than the first threshold value T1, determining that the audio of the playing content cannot be clearly identified by the user in the current noise environment, and determining that the volume state of the playing content is an abnormal volume state. If the ratio of the first energy value E1 to the second energy value E2 of the terminal device in the current environment is smaller than or equal to the first threshold T1, it is determined that the user can clearly identify the audio of the played content in the current noise environment, and it is determined that the volume state of the played content is a normal volume state, and no volume gain is needed.
The sample audio file can be a normal volume audio file, and the normal volume audio file is a file in which when the volume of the terminal equipment is adjusted to the maximum when the audio file is played in a set scene, the sound output by the loudspeaker meets the requirements of a user.
It should be noted that, in steps 201 to 203, which are a manner of determining the abnormal volume state according to the embodiment of the present invention, it may be determined whether the volume state of the currently played content is the abnormal volume state or the abnormal volume state according to a comparison result between a ratio of ambient noise collected by a microphone of the terminal device and energy of sound input to a speaker and a preset first threshold.
In the embodiment of the present invention, the lengths of the first preset time period t1 and the second preset time period t2 may be set according to actual requirements, such as 2s or other time lengths. The second time period t2 is the first time period after t1, such as the first time period is 0-2 s, and the second time period is 2-4 s.
It should be noted that, in the embodiment of the present invention, in the first time period of the file playing, since there is no time period before the time period, the first preset time period may be set to be null when the file is played, and the second time period is the first preset time period. For example, the playing time of the file is 5 minutes, and the length of the time period is 2s, then the time period of the playing progress of 0 to 2s is used as the second preset time period, and the first preset time period corresponding to 0 to 2s is set to be empty. The energy average Eb of the audio energy input to the loudspeaker is collected within a second preset time period of 0-2 s, the first energy average corresponding to the first preset time period of 0-2 s is an initial energy value B0, and the initial energy value B0 is obtained by playing audio files with normal volume in different audio formats in different scenes in advance and then counting the audio files.
After the playing progress reaches a second time period, for example, 2 to 4 seconds, the second preset time period is 2 to 4 seconds, and the first preset time period is 0 to 2 seconds. Then, at this time, a second energy average value of the sound signal within 2-4 s may be obtained, and a first energy average value of the sound signal within a first preset time period may also be obtained. It should be noted that the first energy average value can be determined according to the preset initial energy value B0, so as to ensure that the volume status determination process is more accurate.
In the embodiment of the present invention, the preset second threshold T2 may be obtained through experiments, for example, T2 may be determined by a ratio between the audio energy of the sample audio file and the average of the first energies of the sample audio file, which can be identified according to the actual hearing of the user, by playing the sample audio file with different input audio energies. And if the ratio of the second energy mean value to the target value is greater than a preset second threshold value, determining that the playing content is an old file, and the playing effect of the old file cannot meet the hearing requirement of the user, and determining that the volume state of the playing content is an abnormal volume state. And if the ratio of the second energy mean value to the target value is smaller than or equal to a preset second threshold, determining that the playing effect of the playing content can meet the hearing requirement of the user, and determining that the volume state of the playing content is a normal volume state without volume gain.
Wherein, the ratio between the second energy mean value and the target value can be obtained by the following formula (1):
B1＝Eb/(B0+Eb) (1)
wherein, B1 is the ratio between the second energy mean value and the target value, and the target value is (B0+ Eb).
If B1 is greater than T2, the volume status is an abnormal volume status, and if B1 is less than or equal to T2, the volume status is a normal volume status.
In the embodiment of the present invention, the first energy mean value may also be dynamically updated in the process of using the terminal device, so as to adapt to the change of the playing content. Specifically, when the ratio between the second energy mean value and the target value is less than or equal to a preset second threshold, the first energy mean value may be updated with reference to the following formula (2):
b0_ new ═ c × B0_ old + (1-c) × Eb, where 0< c <1 (2) the B0_ old refers to the first energy average value of the first time period, the Eb refers to the second energy average value, the B0_ new refers to the updated first energy average value, and the c is the audio energy adjustment parameter, which can be set according to the actual demand.
For example, the second predetermined time period is 0 to 2s, the second energy mean value is Eb, and the first energy mean value corresponding to the first predetermined time period of 0 to 2s is the initial energy value B0. If the B1 is less than or equal to T2 within 0-2 s, which indicates that the audio volume of the played content is normal, B0 needs to be updated according to formula (2), that is, the B0_ new is obtained, and then B0_ new is used as B0 of 0-2 s. And after the second preset time period is changed to 2-4 s, obtaining Eb within 2-4 s, wherein the first energy mean value of the corresponding first preset time period is B0 of 0-2 s after updating, continuing to calculate the formula (1), and if the calculated B1 is less than or equal to T2, continuing to update the B0 according to the formula (2).
And when the ratio of the second energy mean value to the target value is larger than a preset second threshold value, continuing to use the first energy mean value in a first preset time period as the first energy mean value in a second preset time period.
As in the previous example, for a second preset time period of 0-2 s, if the calculated B1 is greater than T2, then B0 is not updated and the initial energy value B0 continues as the first energy mean of 0-2 s. For the second preset time period of 2-4 s, if the calculated B1 is greater than T2, the B0 is not updated, and the first energy average value B0 corresponding to the first preset time period of 0-2 s is continuously used as the first energy average value corresponding to 2-4 s. And so on for other cases.
It can be found that the first energy mean value is not necessarily fixed and may be dynamically updated in real time according to different playing contents played by a user. The second energy mean value is not necessarily fixed, and may be dynamically updated in real time according to different playing contents played by the user. Then, for a file with audio data, it is possible that the audio volume of a part of audio segments is normal, and the audio volume of a part of audio segments is abnormal, then the sound signal of the audio segment with the abnormal audio volume can be compensated, so that the adjustment can be performed more accurately for the abnormal audio segment in the audio content.
And 208, displaying two up-adjusting modes if receiving a triggering operation of a user on a volume increasing key under the condition that the volume state is an abnormal volume state and the volume component of the terminal device is adjusted to the maximum volume, wherein the two up-adjusting modes comprise a first up-adjusting mode and a second up-adjusting mode, and determining that the first input is received every time the triggering operation on the volume increasing key is received under the condition that the selection operation on any one of the two up-adjusting modes is received.
In the embodiment of the present invention, referring to fig. 3, a schematic diagram of a volume mode display interface of a terminal device is shown, when a user clicks a volume component outside the terminal device to the maximum, a long-time pressing operation for a preset time period is performed on a volume increase button of the volume component, so as to start an intelligent multi-level mode for volume adjustment, and an up mode selection option including an equal interval up mode and a self-adaptive up mode is displayed on the display interface of the terminal device for the user to select. After the user selects any one of the up-regulation modes, the user can perform first input by clicking the volume component of the terminal equipment again, and the first input can be single click operation of the user or long press operation of the user. Of course, there may be only one up-regulation mode, and the first input may be directly determined without the user performing a selection operation for the up-regulation mode.
Further, referring to fig. 4, if the user wants to exit the intelligent multi-stage mode, the user may gradually exit the intelligent multi-stage function by clicking the volume-decreasing button of the volume component, so as to exit the intelligent multi-stage function, at this time, the volume of the audio input by the speaker of the terminal device is adjusted back to the original maximum volume of the audio component, and when the user continues to click the volume-decreasing button of the volume component, the power of the speaker is decreased, so as to decrease the volume played by the speaker.
In the embodiment of the present invention, the first up-regulation mode is an equal-interval up-regulation mode, and referring to fig. 5, after selecting the equal-interval up-regulation mode, a user may increase the input audio energy of the speaker by a fixed amount by clicking a volume up button in the volume component each time, for example, by clicking the volume up button each time, the volume may be increased by 3db (decibel) or 6db (decibel). In this case, each time the user clicks the volume up button, the sound signal to be input to the speaker may be gained, and the gain may be increased by 3db or 6 db.
The equal-interval up-regulation mode of the embodiment of the invention has simple regulation strategy, and can complete the regulation of the intensity of the sound signal of the audio data under the condition of avoiding large calculation amount of the terminal equipment.
In the embodiment of the present invention, referring to fig. 6, a schematic structural diagram of a terminal device is shown, where a microphone mic1 is arranged on the lower right side of the terminal device, a microphone mic2 is arranged on the upper left side of the terminal device, and a speaker is arranged on the lower left side of the terminal device. If the user selects the second up-regulation mode, i.e. the adaptive up-regulation mode, then the first energy value of the ambient noise is collected through the mic1, the second energy value of the ambient noise is collected through the mic2, and the audio energy of the sound signal input to the speaker is collected.
In the embodiment of the present invention, the second amplification factor h for performing gain on the input audio energy of the playing content may be specifically obtained by the following formula (3):
h＝An*E1/E2 (3)
an is a first amplification factor of the terminal device which is adjusted up from the minimum to the maximum, E1 is a first energy value of mic1, E2 is a second energy value of mic2, and h is An updated second amplification factor. And according to each first input of the user, the sound signal of the playing content is gained through the determined amplification factor.
Optionally, referring to fig. 7, the step 211 includes:
In the embodiment of the present invention, considering that when a speaker in a terminal device plays audio, the audio energy of actual environmental noise collected by the first microphone and the second microphone may interfere with each other, and therefore the first energy value and the second energy value need to be corrected, specifically, the first energy value may be corrected by the following formula (4), and the second energy value may be corrected by the following formula (5) to obtain the second value:
e1＝N+An*E (4)
e2＝N+An*E*(1–a),0<a<1 (5)
the E1 is a first value, the E2 is a second value, the N is An audio energy value of the collected environmental noise, the An is a first amplification coefficient, the E is An input audio energy value input to the loudspeaker, and the a is An energy attenuation factor of the loudspeaker playing sound reaching the mic2 relative to the mic 1.
Due to the fact that the two microphones are adopted, the energy attenuation rule that sound signals played by the loudspeaker reach the two microphones is utilized, the audio amplification coefficient is calculated, and the sound of subsequent playing can be adjusted more quickly and effectively to meet the user requirement.
And 212, amplifying the audio energy corresponding to the audio energy value according to the second amplification factor.
In the embodiment of the present invention, each time the user clicks the volume up button, the volume up button is recorded as a first input, and the sound signal of the playing content is dynamically gained through the second amplification factor determined by the above formula (2). Specifically, referring to fig. 8, a schematic diagram of an adaptive up-tuning mode of a terminal device is shown, where each time a user clicks a volume up button in a volume component on the side of the terminal device to increase the volume, the volume is increased in a recursive manner according to the current volume, so that the user can quickly adjust the volume to a desired volume.
This step can refer to the detailed description of step 104, which is not repeated here.
In the audio playing method in the embodiment of the invention, when the user adjusts the volume component of the terminal device to the maximum volume, the user can select the equal-interval up-regulation mode or the self-adaptive up-regulation mode according to the clicking operation of the volume increasing key of the volume component by the user, so that the sound signal input into the loudspeaker is further increased according to the environment noise according to the selection operation of the user on the up-regulation mode, and the requirement of the user on larger volume is met. In addition, when a file with audio data is played, the adjusting process of the embodiment of the invention can be carried out on the part of the file with abnormal volume, so that the adjustment is more accurate.
With the above description of the audio playing method according to the embodiment of the present invention, the terminal device according to the embodiment of the present invention will be described with reference to the accompanying drawings.

The ending time of the second preset time period is the current time, the second preset time period is a time period after the first preset time period, and the second preset time period is an adjacent time period to the first preset time period.
