Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The volume adjusting method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, an embodiment of the present application provides a volume adjustment method, which may be applied to an electronic device, such as a mobile phone, a tablet computer, and the like. The method may comprise the steps of:
step 101: and acquiring an attenuation function of the current environment of the electronic equipment.
Wherein the attenuation function is a function of the attenuation amplitude of the sound signal and the distance.
In addition, a sound will be weaker and weaker in the propagation process, i.e., the attenuation of the sound. And the attenuation of sound is distance dependent, i.e. the longer the distance, the greater the amplitude of attenuation of the sound signal. Therefore, the actual attenuation amplitude of the sound signal can be further calculated by obtaining the attenuation function of the current environment of the electronic device, so that the volume of the electronic device is adjusted according to the actual attenuation condition of the sound signal in the environment, the probability that other users except the user holding the electronic device hear the conversation content of the electronic device is reduced, and the leakage probability of the privacy information is reduced.
Step 102: a first attenuation magnitude of the sound signal at a first distance is determined based on the attenuation function.
The first distance is the distance from the electronic equipment to the position where the target person is located.
Here, the target person is a person other than the user holding the electronic device, and may also be referred to as an auditor. The first distance may be predetermined, for example, according to the rule that the distance between people is generally greater than 20cm, the first distance may be set to be 20cm; alternatively, the electronic device may actually detect the closest distance between an onlooker near the electronic device and the electronic device, for example, the distance between the onlooker near the mobile phone and the mobile phone may be detected by an infrared sensor, so as to select the minimum distance as the first distance.
Since the amplitude of the sound signal gradually decreases with the increase of the distance, if the hearing person closest to the electronic device cannot hear the call content of the electronic device, other hearing persons farther away cannot hear the call content of the electronic device. Therefore, the minimum distance between persons or the minimum distance between the listeners and the electronic device can be used as the first distance.
Step 103: and adjusting the volume of a receiver of the electronic equipment according to the first attenuation amplitude.
Therefore, when the electronic device answers the call, the playing volume of the receiver of the electronic device can be adjusted through the steps 101 to 103, so that the probability that other users except the user holding the electronic device hear the call content is reduced, and the leakage probability of the privacy information is reduced.
As can be seen from the foregoing steps 101 to 103, in the embodiment of the present application, an attenuation function of the current environment of the electronic device can be obtained, so as to determine a first attenuation amplitude of the sound signal at a first distance according to the attenuation function, and further adjust the volume of a receiver of the electronic device according to the first attenuation amplitude, where the attenuation function is a functional relationship between the attenuation amplitude of the sound signal and the distance, and the first distance is a distance from the electronic device to a location where the target person is located.
However, in the prior art, when a call is answered, the volume of the receiver may be relatively large, and at this time, a user can only adjust the volume manually, and most of the time, there is no way to judge how large the volume of the receiver is relatively suitable for the user's own call, and call information is not leaked. The embodiment of the application needs a mechanism which can avoid manual volume adjustment and judge the volume, so that the quality of the call can be ensured, and the call content can not be revealed.
In other words, in the embodiment of the present application, the attenuation amplitude of the sound signal at the distance from the electronic device to the location of the target person can be automatically calculated according to the attenuation function of the current environment of the electronic device, so as to adjust the volume of the receiver of the electronic device according to the attenuation amplitude, that is, in the embodiment of the present application, the volume of the receiver of the electronic device can be adjusted according to the actual attenuation condition of the sound signal in the environment, so that the probability that other users except the user holding the electronic device hear the call content of the electronic device can be reduced without manually adjusting the volume by the user, and further, the leakage probability of the privacy information can be reduced.
In addition, it should be noted that the volume adjusting method in the embodiment of the present application may be applicable to a scenario where a user answers a call and the electronic device is close to a human ear, and may also be applicable to a scenario where the user answers the call and the electronic device is not close to the human ear.
Optionally, the obtaining an attenuation function of an environment in which the electronic device is currently located includes:
controlling the telephone receiver to send an ultrasonic signal and recording the transmitting amplitude of the ultrasonic signal;
controlling a microphone of the electronic equipment to receive the ultrasonic signal and detecting the receiving amplitude of the ultrasonic signal;
determining a constant target value in a functional relation expression according to the transmitting amplitude, the receiving amplitude, the first target distance and the predetermined functional relation expression of the attenuation amplitude and the distance of the sound signal;
substituting the target value into the function relation expression to obtain an attenuation function of the current environment of the electronic equipment;
the first target distance is the distance between the setting position of the telephone receiver on the electronic equipment and the setting position of the microphone on the electronic equipment.
In the embodiment of the application, a receiver and a microphone are arranged on the electronic device, wherein the receiver and the microphone are fixed at the same position on the electronic device, and the distance between the receiver and the microphone is a fixed value, so that when a sound signal is emitted by the receiver and received by the microphone, the attenuation of the sound signal at the first target distance can be obtained. Therefore, the target value of the constant in the function relation between the known sound signal and the distance can be determined, and the attenuation function of the current environment of the electronic equipment can be obtained. Therefore, in the embodiment of the application, the existing telephone receiver and the existing microphone on the electronic equipment can be utilized to obtain the attenuation function of the current environment of the electronic equipment, and the addition of other devices to the electronic equipment is avoided, namely, the cost is avoided being increased.
The receiver sends ultrasonic signals, so that the condition that the ears hear the signals to influence the listening of the audio normally played by the electronic equipment is avoided.
In addition, for example, it is known
Where a denotes an attenuation coefficient, i.e., an attenuation amplitude per unit distance of the sound signal on the propagation path, x denotes a distance from the sound source, a denotes a sound pressure at the sound source (i.e., an emission amplitude of the sound signal), a denotes 0 Representing the sound pressure (i.e., the received amplitude of the sound signal) at the location of measurement, can be found
Where F (z) represents the amplitude of attenuation of the sound signal over a distance z.
In the embodiment of the present application, the receiver sends the ultrasonic signal, and the microphone receives the ultrasonic signal, so as to obtain the transmission amplitude a of the ultrasonic signal T And receive amplitude A R Wherein the distance between the receiver and the microphone is known as x 1 Then can be substituted into the formula
In order to obtain the attenuation coefficient
The attenuation function of the electronic equipment in the current environment is obtained as follows:
thus, knowing a distance, substituting the attenuation function, a corresponding attenuation magnitude can be obtained, e.g.
Optionally, the controlling the receiver to send an ultrasonic signal includes:
controlling the telephone receiver to send the ultrasonic signal under the condition that the residual electric quantity of the electronic equipment is greater than a first preset threshold value and a second target distance is greater than a second preset threshold value, or under the condition that the residual electric quantity of the electronic equipment is greater than the first preset threshold value and a difference between an environmental parameter of a current environment of the electronic equipment and a reference environmental parameter is greater than a third preset threshold value;
the second target distance is the distance between the current geographical position of the electronic equipment and the geographical position of the telephone receiver when the telephone receiver sends the ultrasonic signal last time;
the reference environment parameter is a parameter of an environment where the electronic device is located when the receiver sends the ultrasonic signal last time.
Wherein the environmental parameter comprises at least one of temperature, humidity, and ambient noise parameter.
Optionally, the obtaining an attenuation function of an environment in which the electronic device is currently located further includes:
and determining the attenuation function of the environment where the electronic equipment is located, which is obtained last time, as the attenuation function of the environment where the electronic equipment is located when the remaining power of the electronic equipment is less than or equal to the first preset threshold, or the second target distance is less than or equal to the second preset threshold, or the difference between the environmental parameter of the environment where the electronic equipment is located and the reference environmental parameter is less than or equal to the third preset threshold.
In the embodiment of the application, the existing receiver and microphone on the electronic device are used to obtain the attenuation function of the current environment of the electronic device, which does not increase the cost, but the attenuation function needs to be calculated before the electronic device answers the call.
In which the degree of attenuation of sound is influenced by the environment, e.g. both temperature and humidity affect the sound propagation (e.g. if the relative humidity is reduced from 80% to 20% at 15 c, the sound pressure level at 800m from the sound source is reduced by 3dB (frequency 100 Hz)), so that it is necessary to recalculate the attenuation function when the environment changes. But in order to save power consumption and environmental characteristics in combination with sound propagation, it is not necessary to recalculate the attenuation function when no change in the environment of the electronic device is detected.
In addition, whether the environment of the electronic equipment is changed or not can be determined by detecting whether the position of the electronic equipment is changed or not; whether the environment of the electronic device changes or not can also be determined by directly detecting the environmental parameters of the environment of the electronic device.
It follows that the last decay function can be followed without recalculating the decay function when one of the following conditions is satisfied:
condition 1: the residual electric quantity of the electronic equipment is less than or equal to a first preset threshold value;
condition 2: the distance between the current position of the electronic equipment and the position of the last time when the telephone receiver sends the ultrasonic signal is smaller than or equal to a second preset threshold value; for example, when it is obtained from a Global Positioning System (GPS) or other applications that the electronic device does not enter a new environment, for example, the location is an area a, the previous attenuation function is used, and no ultrasonic calibration is performed, so as to achieve the purpose of saving power consumption;
condition 3: the difference between the environmental parameter of the current environment where the electronic equipment is located and the reference environmental parameter is smaller than or equal to a third preset threshold;
it should be noted that, when the environmental parameter includes multiple parameters, a threshold may be set for each parameter, for example, when the environmental parameter includes a temperature parameter, a humidity parameter, and an external noise parameter, where the third preset threshold may include a temperature threshold, a humidity threshold, and a noise threshold, and then the condition 3 may specifically be: the difference between the temperature of the environment where the electronic equipment is located and the temperature in the reference environment parameter is smaller than or equal to a temperature threshold value, the difference between the humidity of the environment where the electronic equipment is located and the humidity in the reference environment parameter is smaller than or equal to a humidity threshold value, and the difference between the external noise parameter of the environment where the electronic equipment is located and the external noise parameter in the reference environment parameter is smaller than or equal to a noise threshold value; correspondingly, if the difference between the environmental parameter of the current environment where the electronic device is located and the reference environmental parameter is greater than a third preset threshold, the method may specifically be: the difference between the temperature of the current environment of the electronic device and the temperature in the reference environment parameter is greater than a temperature threshold, or the difference between the humidity of the current environment of the electronic device and the humidity in the reference environment parameter is greater than a humidity threshold, or the difference between the external noise parameter of the current environment of the electronic device and the external noise parameter in the reference environment parameter is greater than a noise threshold.
It can be understood that, when the previous attenuation function is used, if the first distance is a preset fixed value, the first attenuation amplitude of the sound signal at the first distance does not need to be calculated according to the attenuation function at this time, and the volume of the electronic device is adjusted directly according to the first attenuation amplitude obtained by the previous calculation.
Optionally, before adjusting the volume of the receiver of the electronic device, the method further includes:
determining a second attenuation amplitude of the sound signal at a second distance according to the attenuation function, wherein the second distance is the distance between the electronic equipment and the ear of the person holding the electronic equipment;
the adjusting the volume of a receiver of the electronic device according to the first attenuation amplitude includes:
and adjusting the volume of a receiver of the electronic equipment according to the first attenuation amplitude and the second attenuation amplitude.
However, since the electronic device is held by the user's hand to make a call, the electronic device is spaced apart from the ear by a predetermined distance, and therefore, in order to avoid an excessive reduction in the sound signal emitted from the receiver, a second attenuation level of the sound signal at the second distance (i.e., the distance between the electronic device and the ear of the person holding the electronic device) may be calculated, and the sound volume of the receiver of the electronic device may be commonly conditioned by combining the first attenuation level and the second attenuation level.
Optionally, the adjusting, according to the first attenuation amplitude and the second attenuation amplitude, the volume of a receiver of the electronic device includes:
calculating the sum of the first attenuation amplitude and a target parameter to obtain a volume upper limit value, wherein the target parameter is the amplitude of a sound signal with the minimum volume which can be heard by human ears;
calculating the sum of the second attenuation amplitude and the target parameter to obtain a volume lower limit value;
and adjusting the volume of a receiver of the electronic equipment to be between the volume lower limit value and the volume upper limit value.
If the volume upper limit value exceeds the volume upper limit value, the conversation content of the electronic equipment can be heard by an onlooker;
if the lower limit value of the sound volume is the sum of the amplitude of the sound signal with the minimum sound volume that can be heard by the human ear and the second attenuation amplitude, the sound volume of the receiver is at the minimum of the lower limit value of the sound volume, and if the lower limit value of the sound volume is smaller than the lower limit value of the sound volume, a user holding the electronic equipment may not hear the conversation content.
Therefore, the embodiment of the application can enable the user to hear the sound of the mobile phone receiver to the maximum extent, and meanwhile, the privacy of the user can be protected to the maximum extent.
Optionally, the obtaining an attenuation function of an environment in which the electronic device is currently located includes:
under the condition of receiving a call request, displaying a target control;
receiving a target operation on the target control;
responding to the target operation, and acquiring the attenuation function of the current environment of the electronic equipment;
after the volume of the receiver of the electronic device is adjusted, the method further comprises:
and receiving the call according to the volume adjusted by the receiver.
The target control can be an icon with a 'private call' identifier, and the target operation can be dragging operation, clicking operation and the like on the target control.
Therefore, in the embodiment of the application, if the electronic device receives a call request, the target control may be displayed, and then, if the electronic device receives a target operation of the user on the target control, it indicates that the content of the current call is not expected to be heard by other users, the electronic device is triggered to execute the foregoing steps 101 to 103 to adjust the volume of the receiver of the electronic device, so as to listen to the call with the adjusted volume, so that the user holding the electronic device hears the sound of the receiver, and at the same time, the probability that other users hear the content of the call is reduced, thereby reducing the probability of leaking the privacy information.
In summary, when the volume adjustment method according to the embodiment of the present application is applied to a mobile phone, the specific implementation manner of the volume adjustment method can be as shown in fig. 2, and the mobile phone is provided with a receiver 305, a secondary microphone 306, and a primary microphone 307.
Referring to fig. 2, when answering a call, the implementation of the volume adjustment method according to the embodiment of the present application is as follows:
when the user receives an incoming call or a voice call, the display interface of the mobile phone can be as shown in fig. 3, wherein if the user slides from the first icon 301 to the second icon 302 on the touch screen of the mobile phone, a general answering mode is entered (i.e. the user can directly answer the call, and the user can manually adjust the volume); if the phone is private, the user can slide from the first icon 301 to the third icon 303, so as to trigger entering a private call mode; if the user slides from the first icon 301 to the fourth icon 304, the call is hung up;
after entering the private call mode, first checking whether the remaining power of the mobile phone is greater than a first preset threshold, and when the remaining power of the mobile phone is greater than the first preset threshold, determining whether a second target distance between the current position of the mobile phone and the position of the mobile phone in the previous private call mode is greater than a second preset threshold (i.e., determining whether current position information changes), if the second target distance is greater than the second preset threshold, calculating an attenuation function through a receiver and a secondary microphone, that is, sending an ultrasonic signal through the receiver 305, and receiving the ultrasonic signal through the secondary microphone 306, so as to calculate an attenuation function of the current environment of the mobile phone (i.e., f (z), where z represents a distance, and f (z) represents an attenuation amplitude) through the transmission amplitude of the ultrasonic signal and the reception amplitude of the secondary microphone, and a fixed distance between the receiver 305 and the secondary microphone 306 (i.e., distance d1 shown in fig. 2 is fixed); then, according to the distance between people generally being greater than 20cm (i.e. d2 shown in fig. 2 is generally greater than 20 cm), the minimum amplitude value Imin of the sound that can be heard by a general person, and the distance between the ear of the person and the mobile phone when the person answers the call being within 1cm (i.e. d0 shown in fig. 2 is generally less than 1 cm), the volume adjustment range of the receiver is calculated: imin + f (1 cm) -Imin + f (20 cm), so that the volume of the receiver is adjusted to be within the range, and then the call is answered to start communication;
if the residual electric quantity of the mobile phone is smaller than or equal to a first preset threshold value, or the second target distance is smaller than or equal to a second preset threshold value, adjusting the volume of the receiver to be within the volume adjusting range used in the last private call mode; namely, under the condition that the mobile phone does not meet the conditions of the electric quantity requirement and the position information change, the volume of the receiver in the next private call can be set according to the volume adjusting range used in the previous private call, so that the privacy of the user can be protected as much as possible, the detection time can be saved, and the detection power consumption can be saved.
Therefore, the volume adjusting method can protect the privacy of the user as much as possible while multiplexing the current mobile phone structure, and meanwhile, a scheme for saving power consumption is adopted for the detection scheme, so that the use duration and the privacy are both ensured.
It can be understood that the volume adjusting method in the embodiment of the present application can be applied to a folding screen mobile phone and a terminal with a similar structure.
According to the volume adjusting method provided by the embodiment of the application, the execution main body can be a volume adjusting device. In the embodiment of the present application, a method for executing volume adjustment by a volume adjustment device is taken as an example to describe the volume adjustment device provided in the embodiment of the present application.
