Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

Referring to fig. 1, a call interface in a mobile terminal according to an embodiment of the present application is shown, where the call interface is an interface displayed when the mobile terminal is in a call mode, where the call mode includes an earphone call mode and a non-earphone call mode, and the non-earphone call mode includes a hands-free mode and an earphone mode. Specifically, the earphone call mode is a mode in which the mobile terminal uses a currently connected audio peripheral to perform a call, wherein the audio peripheral includes an earphone and a microphone, a user inputs voice through the microphone of the peripheral, and receives a voice signal through the earphone. In the hands-free mode, the mobile terminal receives voice input by a user through a microphone of the mobile terminal and plays the voice through a loudspeaker of the mobile terminal. In the earphone mode, the mobile terminal receives voice input by a user through a microphone of the mobile terminal, and plays the voice through an earphone of the mobile terminal.

In the case that the mobile terminal is in the call interface shown in fig. 1, the user can adjust the current call volume through the volume key, where the call volume is the volume of the voice played by the speaker or the receiver in the call state. As shown in fig. 1, the mobile terminal is provided with volume adjustment keys 130, and particularly, the volume adjustment keys 130 include a first volume key 131 and a second volume key 132, the first volume key 131 being used to increase the call volume, and the second volume key 132 being used to decrease the call volume.

After the mobile terminal responds to the call request input by the user, for example, a call answering key is clicked, the mobile terminal answers the call with a preset volume, that is, when answering the call, the call volume is the preset volume, wherein the preset volume is the call volume preset by the user.

However, when a call is made, the volume of the call may be too small or too large due to too small or too large a preset value, and the volume of the call needs to be adjusted manually by the user through controlling the volume key, which may affect the operation of the user when answering the call and reduce the user experience.

In order to solve the technical defect, an embodiment of the present application provides a call control method for improving experience of volume adjustment of a user during a call, and specifically, please refer to fig. 2, the method includes: s201 to S204.

S201: when the mobile terminal is monitored to be in a call mode, determining whether the type of the call mode is an earphone call mode.

When the mobile terminal calls, namely the phone rings or the vibration reminding rings, the mobile terminal can detect and display a call interface on a screen. And the user clicks an answering key in the incoming call interface to establish call connection between the current SIM card number of the mobile terminal and the incoming call number. Specifically, the phone state of the mobile terminal may be monitored through a phone manager in the system of the mobile terminal, thereby enabling monitoring whether the mobile terminal is in a talk mode. The phone manager is an application module in the system of the mobile terminal, and the user obtains the call state of the mobile terminal, for example, when the system of the mobile terminal is an android system, the phone manager is TelephonyManager.

The type of the call mode of the mobile terminal can be determined by detecting several state values of the mobile terminal. Specifically, whether the mobile terminal is connected with the earphone or not is judged, specifically, the judgment can be made by checking the state of the earphone connecting hole of the mobile terminal, for example, when the earphone connecting hole of the mobile terminal is connected with the earphone, a first state value is returned, when the earphone in the connecting hole is pulled out, a second state value is returned, and whether the current mobile terminal is connected with the earphone or not can be determined by detecting the first state value and the second state value. Specifically, the android system transmits a broadcast when the earphone is plugged in or pulled out, so that the mobile terminal can determine whether the earphone is connected to the mobile terminal currently by monitoring the broadcast. Thus, it can be determined whether the mobile terminal is in the headset talk mode.

And the listening to the earpiece mode and the hands-free mode may be determined by listening to a state value of a key for switching between the earpiece mode and the hands-free mode. For example, in the call interface shown in fig. 1, a hands-free button is displayed, and the user clicks the hands-free button, and the hands-free button is selected and changes in color in appearance to indicate that the hands-free button is pressed. The mobile terminal detects whether the hands-free key is in the selected state, if so, the mobile terminal is judged to be in the hands-free mode, and if not, the mobile terminal is judged to be in the receiver mode. It should be noted that the listening to the earpiece mode and the hands-free mode is performed when the mobile terminal is in the non-earpiece phone call mode.

S202: and if the mobile terminal is not in the earphone communication mode, acquiring the distance between the mobile terminal and the user.

And if the mobile terminal is in the non-earphone call mode, acquiring the distance between the mobile terminal and the user. Specifically, a distance sensor on the mobile terminal, for example, a proximity light sensor, which is generally disposed at an earpiece position of the mobile terminal, may be used to obtain the distance between the mobile terminal and the user, and when the user receives a call, light emitted from a light emitting unit of the proximity light sensor is reflected by a body (for example, ear) of the user and then enters a light receiving unit of the proximity light sensor, and the distance between the mobile terminal and the user is determined according to the light emitted from the light emitting unit and the time when the reflected light is received.

The embodiment of obtaining the distance between the mobile terminal and the user may be set according to a type of a current call mode in which the mobile terminal is located, specifically, if the call mode is an earpiece mode, the distance between the mobile terminal and the user is determined by a distance sensor installed at an earpiece of the mobile terminal, and the specific embodiment may refer to the above process.

And if the call mode is the hands-free mode, determining the distance between the mobile terminal and the user through a microphone of the mobile terminal. Specifically, the microphone collects voice input by a user, obtains a time difference between the voice collected twice, and determines a distance between the mobile terminal and the user according to the time difference, specifically, the time difference is multiplied by the speed of sound to obtain the distance between the mobile terminal and the user. In addition, a microphone and a loudspeaker of the mobile terminal can be used to form a doppler sensor, specifically, a return volume value of a preset sound signal collected by the microphone of the mobile terminal and returned by the user is obtained, and the distance between the mobile terminal and the user is determined according to the return volume value. The preset sound signal is a sound signal emitted by a loudspeaker of the mobile terminal. Recording a first time point of a sound signal emitted by a loudspeaker and a second time point of the sound signal emitted by the loudspeaker, which is collected by a microphone after the sound signal is reflected by a user, and determining a sound time difference according to the first time point and the second time point, so that the distance between the mobile terminal and the user can be determined according to the sound time difference and the sound propagation speed.

S203: and judging whether the distance is smaller than a preset value.

Wherein the preset value corresponds to the call mode. The preset value is used to determine whether the distance between the mobile terminal and the user is close enough because if the distance between the mobile terminal and the user is too far away, the call volume is less likely to need to be adjusted. Taking the call mode as the earpiece mode as an example, when the distance between the mobile terminal and the ear of the user is greater than or equal to the preset value, it indicates that the ear of the user is far away from the earpiece position of the mobile terminal, and at this time, the call volume does not need to be adjusted, because the user may not move the mobile terminal to the proper answering position of the ear of the user yet. The preset value can be set by the user according to actual needs, and is not limited herein.

In addition, because the requirements for preset values are different in the hands-free mode and the earphone mode, the preset values corresponding to the hands-free mode and the earphone mode are different. As an implementation manner, the preset value corresponding to the hands-free mode is greater than the preset value corresponding to the earpiece mode, so that the distance between the user and the mobile terminal in the hands-free mode is greater than the distance between the user and the mobile terminal in the earpiece mode, and the preset value is set more reasonably.

S204: and adjusting the call volume of the mobile terminal according to the distance.

As an implementation manner, a corresponding relationship between a distance and a call volume is preset in the mobile terminal, where the corresponding relationship includes a plurality of distances and a plurality of call volumes, and each distance corresponds to one call volume. After the distance between the mobile terminal and the user is obtained, according to the corresponding relation, the call volume corresponding to the collected distance between the mobile terminal and the user is found, and the call volume of the mobile terminal is set to be the found call volume.

As another embodiment, the embodiment of adjusting the volume of the mobile terminal according to the distance is as follows: and when the distance is gradually reduced, gradually reducing the call volume of the mobile terminal, and when the distance is gradually increased, gradually increasing the call volume of the mobile terminal.

Specifically, when the mobile terminal answers a call, the volume when the mobile terminal enters the call mode is the preset volume, and when the distance between the mobile terminal and the user is smaller than the preset value, the collected distance between the mobile terminal and the user is continuously reduced as the user continues to approach the mobile terminal to the ear of the user, so that the call volume of the mobile terminal is reduced, that is, on the basis of the preset volume, the call volume of the mobile terminal is also gradually reduced as the distance between the mobile terminal and the user is gradually reduced. Specifically, the preset decibel of the call volume of the mobile terminal may be reduced every time the distance is reduced by the preset length, for example, every 5 millimeters, the call volume of the mobile terminal may be reduced by 5 decibels. Of course, it is also possible to decrease the call volume of the mobile terminal by one step every time the distance is decreased by the preset length, for example, decrease the call volume of the mobile terminal by one step every time the distance is decreased by 5 mm.

For example, when the mobile terminal answers the phone call, the volume when entering the call mode is 100 db, i.e. the preset volume is 100 db. And with the gradual reduction of the distance between the mobile terminal and the user, when the reduction of 5 mm is detected, reducing the call volume of the mobile terminal by 5 db, namely, the call volume of the mobile terminal is 95 db, then continuing to reduce by 5 mm, and when the call volume of the mobile terminal is changed to 90, the call volume of the mobile terminal is sequentially reduced in an arithmetic progression with a tolerance of 5 db. Of course, an equal ratio series or other mathematical model may be sequentially decreased.

For another example, when the mobile terminal answers the phone, the volume when entering the call mode is 10 th gear. As the distance between the mobile terminal and the user gradually decreases, when a decrease of 5 mm is detected, the call volume of the mobile terminal is decreased by 1 st gear, that is, to 9 th gear, and then the decrease of 5 mm is continued, and the call volume of the mobile terminal is changed to 8 th gear. Each gear corresponds to one volume, and the volume is larger when the gear is higher.

Similarly, under the condition that the distance between the mobile terminal and the user is increased and is smaller than the preset value, the mobile terminal is kept away from the ear of the user along with the user, the collected distance between the mobile terminal and the user is continuously increased, the call volume of the mobile terminal is gradually increased along with the gradual increase of the distance between the mobile terminal and the user until the preset volume corresponding to the preset value is reached, namely, when the distance between the mobile terminal and the user is gradually increased to the preset value, the call volume is not automatically adjusted, and the call volume can be manually adjusted by the user. Specifically, the preset decibel of the call volume of the mobile terminal may be increased every time the distance is increased by the preset length, for example, every 5 millimeters, the call volume of the mobile terminal may be increased by 5 decibels. Of course, a gear of the call volume of the mobile terminal may be increased every time the distance increases by the preset length, for example, every time the distance increases by 5 millimeters, the call volume of the mobile terminal is increased by one gear.

In addition, considering that the noise of the environment where the user is located is large, if the adjustment strategy is still adopted in the case of small noise, the voice heard by the user during the call may be poor.

Therefore, the manner of adjusting the call volume of the mobile terminal according to the distance may also be: acquiring current environmental noise of the environment where the mobile terminal is located; and adjusting the call volume of the mobile terminal according to the current environmental noise and the distance.

In some embodiments, the current environmental noise is collected by a microphone to obtain the sound intensity of the current environmental noise. Specifically, the microphone collects current sound, takes a sound signal outside a preset frequency range in the collected sound as current environmental noise, and then obtains the sound intensity of the current environmental noise. The preset frequency range corresponds to a frequency range of human voice, specifically, the preset frequency range may be 300Hz to 1500Hz, and the voice out of the range of 300Hz to 1500Hz in the collected voice is used as the current environmental noise.

And after the current environmental noise is acquired, adjusting the call volume of the mobile terminal according to the current environmental noise and the distance. In one embodiment, the call volume of the mobile terminal is sequentially decreased or increased in an arithmetic progression with the distance between the mobile terminal and the user. The current environmental noise can affect the tolerance of the arithmetic progression, specifically, the volume difference between the volume value of the current environmental noise and the preset standard value is obtained, wherein the preset standard value is the volume value of the sound of the user in the quiet environment measured in advance.

If the volume value of the current environmental noise is greater than the preset standard value, that is, the volume difference between the volume value of the current environmental noise and the preset standard value is greater than zero, it indicates that the current environmental noise is large, the tolerance is equal to the absolute value of the difference between the current tolerance and the volume difference, for example, the current tolerance is 5, the volume difference is 3, and the updated tolerance is 5-3-2, so that the volume reduction range can be reduced under the condition that the distance between the user and the mobile terminal is gradually reduced, so as to avoid that the volume is reduced too fast under the high-noise environment of the user.

If the volume value of the current environmental noise is smaller than the preset standard value, that is, the volume difference between the volume value of the current environmental noise and the preset standard value is smaller than zero, it indicates that the current environmental noise is small, the tolerance is equal to the absolute value of the difference between the current tolerance and the volume difference, for example, the current tolerance is 5, the volume difference is-3, and the updated tolerance is 5+ 3-8, thereby increasing the volume reduction range under the condition that the distance between the user and the mobile terminal is gradually reduced, so that the volume is reduced more quickly when the user approaches the mobile terminal in a quiet environment.

As another embodiment, an embodiment of adjusting the call volume of the mobile terminal according to the current environmental noise and the distance is as follows: acquiring an adjustment strategy corresponding to the current environmental noise according to a preset corresponding relation between the environmental noise and the adjustment strategy; and adjusting the call volume of the mobile terminal according to the acquired adjustment strategy and the distance.

The mobile terminal stores a corresponding relationship between the environmental noise and the adjustment policy in advance, and in the corresponding relationship, different environmental noises correspond to different adjustment policies, so the adjustment policy may be adjustment of the distance adjustment interval, for example, increasing or decreasing the distance adjustment interval.

Specifically, if the volume value of the current environmental noise is greater than the preset standard value, that is, the volume difference between the volume value of the current environmental noise and the preset standard value is greater than zero, it indicates that the current environmental noise is large, and in addition to the above manner of increasing the tolerance, the distance adjustment interval may be increased, for example, the call volume of the mobile terminal is decreased every 5 mm, and is adjusted to decrease the call volume of the mobile terminal every 8 mm.

If the volume value of the current environmental noise is smaller than the preset standard value, that is, the volume difference between the volume value of the current environmental noise and the preset standard value is smaller than zero, it indicates that the current environmental noise is smaller, and the adjustment interval of the distance is reduced, for example, the call volume of the mobile terminal is reduced every 5 mm, and the call volume of the mobile terminal is reduced every 3 mm.

And if the user clicks the answer 1 button, inputting an adjusting instruction, and if the user clicks the answer 2 button, connecting the call with preset volume, which is equivalent to not inputting the adjusting instruction, and not adopting a method for adjusting the call volume according to the distance between the mobile terminal and the user.

As another implementation manner, when it is monitored that the mobile terminal is in a call mode, the posture change of the mobile terminal is acquired. The attitude change can be obtained from a gyroscope or an acceleration sensor in the mobile terminal.

If the posture change is a preset posture, determining that an adjustment instruction is obtained, and executing S302. As an implementation manner, the preset posture is a shake event of the mobile terminal, that is, the mobile terminal swings back and forth in a short time, the posture change of the mobile terminal is obtained, and if the posture change is the shake event, it is determined that the adjustment instruction is obtained.

In addition, other modes can be adopted to input the adjustment instruction, specifically, when the mobile terminal is in a call mode, the mobile terminal detects whether the fingerprint module detects the fingerprint information, if the fingerprint information is detected, the time length of the fingerprint information which is continuously collected is determined, and if the time length is greater than the preset time length, the adjustment instruction is determined to be obtained.
