In order to explain the technical solution described in the present application, the following description will be given by way of specific examples.
Before describing a specific embodiment, an application scenario of the embodiment of the present application is first introduced in fig. 1, where a mobile phone may be in a landscape state when a user of the mobile phone plays a game through the mobile phone. The horizontal screen state is: the transverse width of the mobile phone is longer than the longitudinal width of the mobile phone at the angle of a user; correspondingly, the vertical screen state is as follows: at the user's angle, the vertical width of the phone is longer than the horizontal width of the phone. The embodiment shown in fig. 1 shows that the mobile terminal is currently in the landscape screen state, the first microphone of the mobile phone is located on the left side of the screen in the landscape screen state of the mobile phone (near the top in the portrait screen state), and the second microphone of the mobile phone is located on the right side of the screen in the landscape screen state of the mobile phone (near the bottom in the portrait screen state). The left and right determinations are the orientations expressed by the angle of the user in the landscape screen state of the mobile terminal, and of course, other types of corresponding relationships are possible as long as the first microphone and the second microphone are respectively located on the left side of the screen and the right side of the screen in the landscape screen state of the mobile terminal, the third microphone may be a microphone located on the upper side or the lower side of the screen in the landscape screen state of the mobile terminal, and the third microphone is located on the upper side in the landscape screen state of the mobile terminal in the drawing. When the mobile phone is in a landscape state, the left hand and the right hand of the user respectively hold the left side and the right side of the mobile phone, and the situation that the first microphone and/or the second microphone are blocked and blocked may occur, for example, a part of the first microphone is blocked by the left hand in fig. 1, and the second microphone is blocked by the right hand in fig. 1, the problem that the communication quality with a team friend or the other party is poor when the user plays a game occurs, at this time, the third microphone can be switched to, the probability that the third microphone is blocked in the application scene is small, and the communication quality between the user and the other party can be ensured. Of course, in practical applications, the third microphone may also be a bone conduction microphone, and if the third microphone is a bone conduction microphone, the position of the third microphone is not limited.
Fig. 2 is a schematic flow chart of an implementation of a method for adjusting call quality according to an embodiment of the present application, where as shown in the figure, the method may include the following steps:
step S201, when the mobile terminal is detected to be in the horizontal screen state, acquiring first sound information acquired by a first microphone and second sound information acquired by a second microphone of the mobile terminal at preset time intervals, wherein the first microphone and the second microphone are respectively positioned on the left side of a screen of the mobile terminal and the right side of the screen of the mobile terminal when the mobile terminal is in the horizontal screen state.
In the embodiment of the application, the mobile terminal may be a device capable of performing a call, such as a mobile phone of a user, a tablet computer, and the like. During the time that the microphone of the mobile terminal is turned on, the microphone of the mobile terminal collects sound information. Currently, many mobile terminals are equipped with two microphones: the first microphone and the second microphone can realize the noise reduction function through the double microphones, so that the opposite side can obtain clear voice information of a mobile terminal user. Typically, the first microphone and the second microphone will be disposed near the top and bottom of the mobile terminal, respectively. In practical application, the method can also be applied to mobile terminals with microphones arranged at other positions.
The first microphone and the second microphone collect sound information in real time, and the calculated amount is large when the sound information collected in real time is processed in real time; at the same time, the result of the determination may be inaccurate. According to the embodiment of the application, the first sound information collected by the first microphone and the second sound information collected by the second microphone of the mobile terminal can be obtained at a preset time interval. For example, every 5 minutes, sound information collected by the first microphone and the second microphone respectively between the 5 minutes of the interval is acquired. For convenience of description, the sound information collected by the first microphone may be defined as first sound information, and the sound information collected by the second microphone may be defined as second sound information. Of course, in practice, other definitions or nomenclature may be used.
Step S202, if the first sound information or the second sound information includes the voice information, determining whether both the amplitude value of the first sound information and the amplitude value of the second sound information are smaller than a first threshold.
In the embodiment of the present application, it may be determined whether the first sound information or the second sound information includes voice information to determine whether the user is performing a voice call. When a user carries out voice communication, in order to enable the opposite side to receive clear voice information of the mobile terminal user, the shielded or blocked microphone is switched to the unshielded or blocked microphone. If the user does not make a voice call, even if one or both of the microphones are blocked or plugged, the operation of switching the microphones may not be performed.
Whether the first sound information or the second sound information contains the voice information can be judged by the following method:
the method comprises the steps of storing the characteristic information of the voice information in the mobile terminal in advance, extracting the characteristic information from the first voice information, matching the characteristic information with the pre-stored characteristic information, if the matching is successful, indicating that the first voice information contains the voice information, and judging whether the second voice information contains the voice information. If the matching fails, it is indicated that the first sound information does not contain the voice information, and it is necessary to continuously determine whether the second sound information contains the voice information. Therefore, as long as any one microphone collects voice information, the user can be judged to be in voice communication.
Of course, in practical applications, it may also be determined whether the second voice information includes the voice information first, if the second voice information includes the voice information, it is not necessary to determine whether the first voice information includes the voice information, and if the second voice information does not include the voice information, it may be determined whether the first voice information includes the voice information continuously. The first sound information and the second sound information may be determined at the same time.
In this embodiment of the application, when it is determined that the user is conducting a voice call, it may be continuously determined whether both the amplitude value of the first sound information and the amplitude value of the second sound information are smaller than a first threshold. In practical applications, the volume level, the loudness value, and the like of the first sound information and the second sound information may also be used as reference factors compared with the first threshold value to determine whether the first microphone and the second microphone are occluded.
Step S203, if the amplitude value of the first sound information and the amplitude value of the second sound information are both smaller than a first threshold, switching the currently-turned-on first microphone and second microphone to a third microphone, where the third microphone includes a microphone located on the upper side of the screen of the mobile terminal or the lower side of the screen of the mobile terminal when the mobile terminal is in the landscape state.
In this embodiment, the first threshold may be a preset empirical value, and when the amplitude value of the first sound information and the amplitude value of the second sound information are both smaller than the first threshold, it indicates that the first microphone and the second microphone are simultaneously blocked or plugged. In this case, the third microphone may be switched to, for example, a bone conduction microphone, or a microphone that is disposed at a position where the bone conduction microphone is not easily blocked or blocked, for example, a microphone that is disposed at a top middle position or a bottom middle position of the mobile terminal in a landscape state.
Before comparing the amplitude values of the sound information of the two microphones with a first threshold value, the embodiment of the application judges whether the first sound information or the second sound information contains the sound information, and under the condition that the sound information is contained, the user speaks at present and can perform the operation of switching the microphones; if the voice information is not contained, the user may not be currently talking and may not perform the switching operation. And the condition for switching the microphones is that the amplitude value of the first sound information and the amplitude value of the second sound information are both smaller than a first threshold value, that is, the current collected sound information of the first microphone and the second microphone may cause the opposite party to be unable to hear clearly, the first and second microphones that are currently turned on are switched to a third microphone, which includes a microphone located at an upper side of the screen of the mobile terminal or a lower side of the screen of the mobile terminal in the landscape state of the mobile terminal, when mobile terminal was located the horizontal screen state promptly, the third microphone can not be blockked up in user's operation, through third microphone collection sound information, has avoided being located respectively under the first microphone and the second microphone on the left side of mobile terminal screen and the right side of mobile terminal screen were sheltered from or are blockked up when mobile terminal was horizontal screen state, the problem that speech quality is not good.
Fig. 3 is a flowchart illustrating a method for adjusting call quality according to another embodiment of the present application, where the method includes the following steps:
step S301, when the mobile terminal is detected to be in a horizontal screen state, acquiring first sound information acquired by a first microphone and second sound information acquired by a second microphone of the mobile terminal at a preset time interval.
The content of this step is the same as that of step S201, and the description of step S201 may be specifically referred to, which is not repeated herein.
Step S302, if the first sound information or the second sound information includes sound information, determining whether both the amplitude value of the first sound information and the amplitude value of the second sound information are smaller than a first threshold.
The content of this step is the same as that of step S202, and the description of step S202 may be specifically referred to, which is not repeated herein.
Step S303, if the amplitude value of the first sound information and the amplitude value of the second sound information are both smaller than a first threshold value, and the sound information includes a preset keyword, switching the currently turned on first microphone and second microphone to a third microphone.
In this embodiment, if the amplitude value of the first sound information and the amplitude value of the second sound information are both smaller than the first threshold, it indicates that the first microphone and the second microphone are simultaneously blocked or blocked. The embodiment of the application also sets a condition as follows: the voice information contains predetermined keywords.
The preset keywords may be: inaudible, loud and the like indicate that the opposite party cannot clearly hear the words of the voice information sent by the mobile terminal user. The voice information sent by the opposite party can be played through the loudspeaker of the mobile phone, and after the loudspeaker of the mobile phone is played, the first voice information and the second voice information collected by the first microphone and the second microphone can also collect the voice information sent by the opposite party. Whether the first microphone and the second microphone are blocked or blocked can be determined by judging whether the voice information contained in the first microphone and the second microphone contains preset keywords.
Certainly, in practical applications, the sound information of the other party received by the mobile terminal may also be acquired, and whether the preset keyword is included in the sound information of the other party is determined, for example, an electric signal converted from vibration information of a speaker or an earphone of the mobile terminal is acquired, and the electric signal is converted into third sound information. The voice information of the opposite party can be transmitted to the mobile terminal in the form of a data packet, a loudspeaker or an earphone of the mobile terminal converts the data packet processed by the mobile terminal into vibration, a vibration device in the loudspeaker or the earphone generates the vibration to enable the loudspeaker or the earphone to emit the voice information of the opposite party, and meanwhile, the loudspeaker or the earphone can also generate the vibration generated by the vibration device, i.e. the vibration information is converted into an electric signal, the mobile terminal converts the converted electric signal into sound information again, the voice information is the voice information of the opposite party, which is defined as the third voice information, through which it can be identified whether the opposite party utters the preset keyword, that is, the mobile terminal may regenerate an electric signal from the vibration information converted from the voice of the counterpart by the microphone or the earphone, and judging whether the voice information of the opposite side converted by the electric signal contains preset keywords or not according to the voice information of the opposite side converted by the electric signal. Of course, in practical applications, the input electrical signal of the speaker or the earphone, that is, the driving signal of the speaker and the earphone generating vibration, may also be directly obtained, and the input electrical signal of the speaker or the earphone is converted into the third sound information.
In step S304, if the amplitude value of the first sound information is greater than or equal to the first threshold value, and the amplitude value of the second sound information is smaller than the first threshold value, the first microphone is used as a master microphone to collect sound information, and the second microphone is used as a slave microphone to collect sound information.
In step S305, if the amplitude value of the first sound information is smaller than the first threshold value and the amplitude value of the second sound information is greater than or equal to the first threshold value, the second microphone is used as a master microphone to collect sound information, and the first microphone is used as a slave microphone to collect sound information.
In the embodiment of the present application, determining the relationship between the amplitude value of the first sound information and the amplitude value of the second sound information and the first threshold may generate the following results:
a: the amplitude degree of the first sound information is smaller than a first threshold value, and the amplitude value of the second sound information is smaller than the first threshold value;
b: the amplitude degree of the first sound information is smaller than a first threshold value, and the amplitude value of the second sound information is larger than or equal to a second threshold value;
c: the amplitude degree of the first sound information is greater than or equal to a first threshold value, and the amplitude value of the second sound information is smaller than the first threshold value;
d: the amplitude degree of the first sound information is greater than or equal to a first threshold value, and the amplitude degree of the second sound information is greater than or equal to the first threshold value.
And A, result: the first microphone and the second microphone are blocked or blocked and switched into a third microphone;
b, result: the first microphone is blocked or blocked, the second microphone is used as a main microphone, and the first microphone is used as a slave microphone;
c, result: the second microphone is blocked, the first microphone is used as a main microphone, and the second microphone is used as a slave microphone;
d, result: the first microphone and the second microphone are not blocked, and the switching operation is not performed.
Step S303 is an example of an A result, step S304 is an example of a C result, and step S305 is an example of a B result.
One of the first microphone and the second microphone is used as a main microphone and the other one is used as a slave microphone, so that the effect of reducing noise to improve the call quality can be realized. However, when the amplitude values of the first sound information and the second sound information are one larger than the first threshold and one smaller than the first threshold, the amplitude values of the sound information may actually be different from each other, and even if the switching operation is performed, a good effect may not be obtained.
By way of example, when the first threshold is 10, the amplitude value of the first sound information is 9, and the amplitude value of the second sound information is 11, even if the master-slave relationship between the first microphone and the second microphone is adjusted, the improvement of the call quality is not obvious, so the embodiment of the present application further sets the relationship between the difference value between the amplitude value of the first sound information and the amplitude value of the second sound information and the second threshold.
As another embodiment of the present application, if the amplitude value of the first sound information is greater than or equal to the first threshold, the amplitude value of the second sound information is smaller than the first threshold, and the difference between the amplitude value of the first sound information and the amplitude value of the second sound information is greater than a second threshold, the first microphone is used as a master microphone to collect sound information, and the second microphone is used as a slave microphone to collect sound information;
and if the amplitude value of the first sound information is smaller than the first threshold value, the amplitude value of the second sound information is larger than or equal to the first threshold value, and the difference value between the amplitude value of the first sound information and the amplitude value of the second sound information is larger than a second threshold value, the second microphone is used as a main microphone to collect sound information, and the first microphone is used as a slave microphone to collect sound information.
According to the method and the device, the master-slave relation between the first microphone and the second microphone is switched when the difference value between the amplitude value of the first sound information and the amplitude value of the second sound information is larger than the second threshold value, and therefore invalid switching is avoided.
According to the embodiment of the application, the relation between the amplitude value of the first sound information and the amplitude value of the second sound information and the first threshold value is divided into four cases, and the four cases are described respectively, so that the method and the device can adapt to switching under various conditions, and the quality of conversation can be improved.
As another embodiment of the present application, it may be further configured that the first sound information and the second sound information collected by the first microphone and the first microphone are both smaller than a third threshold, the third threshold is smaller than the first threshold, the third threshold is close to 0, and the voice information of the opposite party includes a preset keyword, in which case, it indicates that the first microphone and the second microphone are completely blocked, and the first microphone and the second microphone may be switched to the third microphone.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an 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 application.
