In some embodiments, the electronic device further comprises an acousto-electric transducer device, i.e. an electronic device, such as a microphone, that converts an acoustic signal into an electrical signal. The number and the positions of the electroacoustic transducer devices and the electroacoustic transducer devices in the electronic equipment are not limited. In this embodiment of the present application, the electronic device further has a sound leakage event detection function, that is, based on the loudness of the sound signal sent by the electroacoustic transducer and the intensity of the environmental noise signal collected by the electroacoustic transducer, whether a sound leakage event occurs is detected.

Referring to fig. 2, an application scenario provided in one embodiment of the present application is shown. The mobile terminal 21 plays the call audio, and the user places the mobile terminal 21 beside the ear to make a call with other people, at this time, it is necessary to detect whether a sound leakage event occurs, and if the sound leakage event occurs, it is necessary to reduce the loudness of the sound signal emitted from the speaker.
As shown in fig. 3, the embodiment of the present application further provides a sound emission control method, which includes the following steps (steps 301-304).
Step 301, obtaining the loudness of a sound signal played by a sound generating component in an electronic device.
The electronic device may be a mobile terminal or a wireless headset. When the electronic device is a mobile terminal, the sound generating component of the electronic device is a speaker component, which can be arranged at the top end of the mobile terminal, or can be arranged at the bottom end of the mobile terminal, or can be arranged at the back of the mobile terminal. When the electronic equipment is a wireless earphone, the sounding component in the electronic equipment is a loudspeaker unit, and the loudspeaker unit is arranged at the earplug part of the wireless earphone.
Loudness, i.e. volume, describes the degree of ringing of a sound, representing the subjective perception of the sound by the human ear, in units of measure of Song, defining 1kHz, and loudness of pure tone at a sound pressure level of 40dB of 1 Song.
In some embodiments, the loudness of the sound signal is determined by the volume level and the loudness of the source signal. The volume level is positively correlated with the loudness of the sound signal, i.e. the higher the volume level, the higher the loudness of the sound signal, and the lower the volume level, the lower the loudness of the sound signal. The loudness of the sound source signal and the loudness of the sound signal also have a positive correlation, that is, the higher the loudness of the sound source signal, the higher the loudness of the sound signal, and the lower the loudness of the sound source signal. The loudness of the sound signal is set to be S, the volume level to be L, the loudness of the sound source signal to be M, and the loudness of the sound signal S to be expressed by the following formula.
S＝m(L+M)。
Wherein m is a preset coefficient. Since M is a preset coefficient, is a fixed value, in the following embodiment, the loudness of a sound signal is represented by (l+m).
In other embodiments, the electronic device further includes an automatic gain circuit (Automatic Gain Control, AGC), which is an automatic control circuit that causes the gain of the amplifying circuit to automatically adjust with the signal strength. The first end of the AGC circuit is electrically connected with the appointed microphone, and the second end of the AGC circuit is electrically connected with the sounding component. Optionally, the electronic device further comprises a digital-to-analog conversion circuit (Digital Analog Converter, DAC) and an analog-to-digital conversion circuit (Analog Digital Converter, ADC), wherein the DAC circuit is disposed between the AGC circuit and the sound emitting component and the ADC circuit is disposed between the AGC circuit and the designated microphone. Optionally, the AGC circuit is disposed inside the DSP circuit.
Referring to fig. 4, the electronic apparatus further includes a DSP circuit 41, a DAC circuit 44, and an ADC circuit 45, the DSP circuit 41 includes an AGC411, the DAC circuit 44 is disposed between the DSP circuit 41 and the sound emitting part 43 (i.e., S), and the ADC circuit 45 is disposed between the AGC circuit and the designated microphone 42.
In this embodiment, the loudness of the sound signal is determined by the volume level, the loudness of the sound source signal, and the gain value of the AGC circuit. When the input signal is small, the AGC circuit is not active, and only after the input signal is increased to a certain extent, the AGC circuit is controlled to reduce the gain along with the increase of the input signal. The gain value of the AGC circuit and the loudness of the sound signal are in positive correlation, namely, the larger the gain value of the AGC circuit is, the higher the loudness of the sound signal is, the smaller the gain value of the AGC circuit is, and the lower the loudness of the sound signal is. The loudness of the sound signal is set to be S, the volume level is L, the loudness of the sound source signal is M, the gain value of the AGC circuit is G, and the loudness of the sound signal S can be expressed by the following formula.
S＝b(L+M+G)。
Wherein b is a preset coefficient. Since b is a preset coefficient, is a fixed value, in the following embodiment, the loudness of the sound signal is represented by (l+m+g).
In some embodiments, when the electronic device is a mobile terminal, step 301 is implemented as: the method comprises the steps of obtaining the loudness of sound signals played by a designated sound generating component in the electronic equipment, wherein the designated sound generating component is a loudspeaker assembly arranged at the top end of the mobile terminal. When the appointed sounding component works, the mobile terminal is in a call state, the requirement of preventing sound leakage exists, and the mobile terminal executes a subsequent detection step of a sound leakage event at the moment so as to avoid the leakage of call audio.
Step 302, the loudness of an ambient noise signal acquired by a designated microphone of an electronic device is obtained.
When the electronic device is a mobile terminal, the microphone is designated as a noise reduction microphone, which can be arranged at the bottom end of the mobile terminal and can also be arranged at the back of the mobile terminal. When the electronic device is a wireless earphone, the appointed microphone is arranged on the outer side of the wireless earphone (such as one side of the wireless earphone, which is away from the auditory canal of the user), and when the user wears the wireless earphone, the pickup port of the microphone faces the outer part of the auditory canal, so that the environment noise signal is facilitated. The electronic device obtains the loudness of the environmental noise signals collected by the designated microphone through a noise estimation method. Noise estimation methods include, but are not limited to: a noise estimation algorithm based on minimum statistics, a recursive average algorithm based on minimum statistics control, an adaptive continuous noise spectrum estimation method, etc.
Step 303, detecting whether a sound leakage event has occurred based on the loudness of the sound signal and the loudness of the ambient noise signal.
The sound leakage event refers to an event in which the leakage amount of the sound signal satisfies a preset condition. The leakage amount of the sound signal refers to the loudness of the sound signal collected by the specified microphone.
The preset conditions are set according to experiments or experience. In some embodiments, the preset condition is that the loudness of the leakage amount of the sound signal is greater than the loudness of the environmental noise signal, in which case, other users can also hear the sound signal played by the sound emitting component of the electronic device, so as to cause privacy leakage. In other embodiments, the preset condition refers to that the loudness of the leakage amount of the sound signal is greater than a preset loudness, where the preset loudness is set according to experiments or experience, which is not limited in the embodiments of the present application.
The judgment condition for the electronic device to judge whether or not the sound leakage event occurs may be determined in a laboratory environment. Referring to fig. 5, a schematic diagram of an experimental environment provided in an embodiment of the present application is shown, where the experimental environment includes: artificial ear 51, electronic device 52, test microphone mic1, sound 53. Wherein the electronic device 52 comprises a speaker and a microphone, the speaker in the electronic device 52 is denoted S and the microphone is denoted mic2.
The distance between the artificial ear 51 and the test microphone mic1 is determined according to reality, and in one example, the distance between the artificial ear 51 and the test microphone mic1 is approximately 50 cm. The sound 53 is used for simulating an ambient noise signal, and is provided on the right side of the test microphone mic 1. The experimenter sets up to play the first test sound signal S through the speaker S in the electronic device 52 0 Second test sound signal s 1 The sound 53 plays the ambient noise signal N. First test sound signal s 0 And a second test sound signal s 1 May be the same or different.
The test system records a first test sound signal s collected by a microphone mic2 of the electronic device 0 Is equal to the loudness s of the first test sound signal acquired by the test microphone mic1 0 Difference betweenAs a first difference. That is, the first difference value X is expressed by the following first formula: x=mic2 (s 0 )-mic1(s 0 ) I.e., x=mic2 (S) -mic1 (S).
The test system records the difference between the loudness of the test noise signal N collected by the test microphone mic1 and the loudness of the test noise signal N collected by the microphone mic1 of the electronic device 52 as a second difference. That is, the second difference Y is expressed by the following second formula: y=mic1 (N) -mic2 (N).
The test system records a second test sound signal s 1 And a second test sound signal s picked up by the microphone mic2 of the electronic device 52 1 As a third difference value. The third difference a is represented by the following third formula: a=s 1 -mic2(s 1 ) I.e., a=s-mic 2 (S).
In the laboratory environment, if it is determined that no sound leakage event occurs, the environmental noise signal mic1 (N) collected by the test microphone mic1 needs to be greater than the collected test sound signal mic1 (S). That is, mic1 (S) <=mic1 (N) (fourth formula).
However, according to the first formula, mic1 (S) =mic2 (S) -X (fifth formula) is available.
From the second formula: mic1 (N) =mic2 (N) +y (sixth formula).
Combining the fourth, fifth and sixth formulas can result in:
mic2 (S) -X < = mic2 (N) +y, i.e. mic2 (S) < = mic2 (N) +y+x (seventh formula).
Further, according to the third formulse:Sup>A, mic2 (S) =s-se:Sup>A (eighth formulse:Sup>A).
The seventh and eighth formulas can be obtained: S-se:Sup>A < = mic2 (N) +y+x, S < = mic2 (N) +y+x+se:Sup>A (ninth formulse:Sup>A).
When S is represented by (l+m), i.e., (l+m) <=mic2 (N) +y+x+a. In this case, it is determined that the sound safety condition, which is a condition to be satisfied without occurrence of a sound leakage event, is satisfied. Conversely, if (l+m) > mic2 (N) +y+x+a, the occurrence of a sound leakage event is described.
When S is represented by (l+m+g), i.e., (l+m+g) <=mic2 (N) +y+x+a. In this case, it is determined that the sound safety condition is satisfied, whereas if (l+m+g) > mic2 (N) +y+x+a), the occurrence of the sound leakage event is described.
In combination with the judgment conditions of the sound leakage event determined in the laboratory environment, the electronic device detects whether the sound leakage event occurs through the following steps.
In step 303a, a first difference value, a second difference value, and a third difference value are obtained.
The first difference is a difference between a loudness of a first test sound signal collected by a designated microphone of the electronic device and a loudness of the first test sound signal collected by the test microphone, the first test sound signal being emitted by a sound emitting component of the electronic device. The second difference is the difference between the loudness of the test noise signal collected by the test microphone and the loudness of the test noise signal collected by the designated microphone of the electronic device. The third difference is a difference between the loudness of the second test sound signal and the loudness of the second test sound signal collected by the designated microphone of the electronic device, where the second test sound signal is emitted by the sound emitting component of the electronic device.
The process of obtaining the first difference, the second difference, and the third difference refers to the above embodiment.
In step 303b, if the loudness of the sound signal is greater than the sum of the loudness of the ambient noise signal, the first difference, the second difference, and the third difference, then it is determined that the sound leakage event occurs.
When S is represented by (l+m), if (l+m) <=mic2 (N) +x+y+a), it is indicated that no sound leakage event occurs; if (l+m) > mic2 (N) +x+y+a, the occurrence of a sound leakage event is described.
When S is represented by (l+m+g), if (l+m+g) <=mic2 (N) +x+y+a, it is indicated that no sound leakage event occurs; conversely, if (l+m+g) > mic2 (N) +x+y+a, the occurrence of a sound leakage event is described.
Step 304, if a sound leakage event occurs, adjusting sound parameters of the sound emitting component, wherein the sound parameters are used for controlling the loudness of the sound signal.
After the sound leakage event is determined, the electronic equipment automatically adjusts sound emission parameters of the sound emission component, wherein the sound emission parameters comprise volume level and/or gain value of the AGC circuit so as to reduce loudness of sound signals, so that the sound signals are not leaked any more, and user privacy can be effectively protected.
The embodiment of the application provides a sounding control method, when a sounding component of electronic equipment sends a sound signal, whether a sounding sound leakage event occurs is detected through the loudness of the sound signal and the loudness of an environmental noise signal collected by a designated microphone in the electronic equipment, and if the sound leakage event occurs, sounding parameters of the sounding component are adjusted to reduce the loudness of the sound signal until the sound leakage event does not occur any more; the technical scheme that this embodiment provided provides a scheme of automated inspection sound leakage incident for electronic equipment can feel the sound leakage incident, later adjusts the sounding parameter of sounding part through in time, so that sound signal no longer takes place to reveal, effectively protects user privacy.
In a first implementation, the sound emission parameters of the sound emission component include a volume level, and the electronic device adjusts the loudness of the sound signal by adjusting the volume level. Such an implementation is described below.
In some embodiments, adjusting the volume level specifically includes the following steps (steps 401-403).
In step 401, if a sound leakage event is sent, a prompt message is sent.
The prompt information is used for prompting the occurrence of the sound leakage event. When the electronic device is a mobile terminal, the prompt information can be at least one of a voice prompt mode, a text prompt mode and a flashing prompt mode. When the electronic device is a wireless earphone, the prompt information can be at least one of a voice prompt mode and a flickering prompt mode.
In one example, the wireless headset emits a "sound leak, please handle in time" to prompt the user.
In another example, the mobile terminal displays a floating window that includes the prompt "sound leakage, please handle in time".
In step 402, a first adjustment amount of a volume level is obtained in response to an adjustment signal for the volume level.
The adjustment signal for the volume level is used to adjust the volume level. When the electronic device detects a sound leakage event, the loudness of the sound signal needs to be reduced, and thus the volume level needs to be reduced, i.e. in the embodiment of the present application, the adjustment signal for the volume level is used to reduce the volume level.
When the electronic equipment is a mobile terminal, a volume adjusting button is arranged on a side frame of the mobile terminal, and when the electronic equipment receives a pressing operation for the volume adjusting button, the mobile terminal receives an adjusting signal for the volume level. Specifically, the volume adjustment button includes a decrease button, and when the mobile terminal receives a pressing operation for the decrease button, an adjustment signal for decreasing the volume level is received.
In some embodiments, the first adjustment amount of the volume level is in positive correlation with the number of operations of the pressing operation, that is, the greater the number of operations of the pressing operation, the greater the first adjustment amount of the volume level, and the lesser the number of operations of the pressing operation, the smaller the first adjustment amount of the volume level. Optionally, a first mapping relationship exists between a first adjustment amount of the volume level and the operation times of the pressing signal, after receiving the pressing operation, the mobile terminal obtains the operation times of the pressing operation, and then determines the first adjustment amount of the volume level based on the first mapping relationship. The first mapping relation may be a functional relation, or may be a correspondence relation between different operation times and different adjustment amounts.
In other embodiments, the first adjustment amount of the volume level is in positive correlation with the operation duration of the pressing operation, that is, the longer the operation duration of the pressing operation is, the larger the first adjustment amount of the volume level is, the shorter the operation duration of the pressing operation is, and the smaller the first adjustment amount of the volume level is. Optionally, a second mapping relationship exists between the first adjustment amount of the volume level and the operation time of the pressing signal, after receiving the pressing operation, the mobile terminal obtains the operation times of the pressing operation, and then determines the first adjustment amount of the volume level based on the second mapping relationship. The second mapping relation can be a functional relation, or can be a corresponding relation between different operation time lengths and different adjustment amounts.
When the electronic equipment is a wireless earphone, a volume adjusting button is arranged at the ear handle part of the wireless earphone, and when a pressing signal aiming at the volume adjusting button is received, the wireless earphone receives an adjusting signal aiming at the volume level. Specifically, the volume adjustment button includes a decrease button, and when the wireless headset receives a pressing operation for the decrease button, an adjustment signal for decreasing the volume level is received. In other possible implementations, the wireless headset receives an adjustment signal for the volume level sent by the mobile terminal, the adjustment signal carrying the first adjustment amount. Wherein a communication connection, such as a bluetooth connection, is established between the wireless headset and the mobile terminal.
Step 403, adjusting the volume level according to the first adjustment amount of the volume level.
In some embodiments, the electronic device subtracts the first adjustment amount from the original volume level to obtain an adjusted volume level, and then adjusts the volume level to the adjusted volume level. Illustratively, the original volume level is 36, the first adjustment of the volume level is 10, the adjusted volume level is 26, and the electronic device adjusts the volume level to 26.
In other embodiments, adjusting the volume level specifically includes steps 404-406 as follows.
Step 404, obtaining a leakage level of the sound leakage event.

In some embodiments, the leakage level is determined based on the interval to which the fourth difference value belongs. The fourth difference is the sum of the loudness of the sound signal and the loudness of the ambient noise signal, the first difference, the second difference and the third difference.
When S is expressed as (l+m), the fourth difference Z is expressed by the following formula.
Z＝(L+M)-(mic2(N)+X+Y+A)。
The greater the value of Z, the greater the severity of the sound leakage event; the greater the value of Z, the lower the severity of the sound leakage event. In some embodiments, the electronic device sets a third mapping relationship between the value interval of Z and the leakage level, and determines the leakage level based on the third mapping relationship after calculating Z.
Step 405, determining a second adjustment amount of the volume level based on the leakage level of the sound leakage event.
The leakage level and the second adjustment amount are in positive correlation. The higher the leak level, the larger the second adjustment amount, and the lower the leak level, the smaller the second adjustment amount. In some embodiments, the electronic device presets a fourth mapping relationship between the leakage level and the volume level, and determines the second adjustment amount based on the fourth mapping relationship after determining the leakage level.

In some embodiments, the electronic device determines a difference between a sum of the loudness of the ambient noise signal, the first difference, the second difference, and the third difference, and the loudness of the sound source signal, as the target volume level, without occurrence of the sound leakage event. I.e., L < = mic2 (N) +x+y+a-M), the electronic device determines any volume level satisfying the above formula as the target volume level.
In some embodiments, the method F of adjusting the volume level provided by steps 407-409 may be expressed as the following formula.

That is, when l+m is equal to or less than mic2 (N) +y+x+a, the volume level L is unchanged, the original user setting value is maintained, and when l+m > mic2 (N) +y+x+a, the volume level L is adjusted to l=mic 2 (N) +y+x+a-M.

When S is expressed as (l+m+g), the fourth difference Z is expressed by the following formula.
Z＝(L+M+G)-(mic2(N)+X+Y+A)。
The greater the value of Z, the greater the severity of the sound leakage event; the greater the value of Z, the lower the severity of the sound leakage event. In some embodiments, the electronic device sets a third mapping relationship between the value interval of Z and the leakage level, and determines the leakage level based on the third mapping relationship after calculating Z.
Step 502, determining an adjustment amount of the gain value based on the leakage level of the sound leakage event.
The leakage level and the adjustment amount of the gain value are in positive correlation. The leakage level and the adjustment amount of the gain value are in positive correlation. That is, the higher the leak level, the larger the adjustment amount of the gain value, and the lower the leak level, the smaller the adjustment amount of the gain value. In some embodiments, the electronic device presets a fifth mapping relationship between the leakage level and the gain value, and determines the adjustment amount of the gain value based on the fifth mapping relationship after determining the leakage level.
In step 503, the volume level is adjusted according to the gain adjustment amount.
In some embodiments, the electronic device subtracts the adjustment amount from the original gain value to obtain an adjusted gain value, and then adjusts the gain value of the AGC circuit to the adjusted volume level.

The sound safety condition is used to characterize the condition satisfied by the absence of a sound leakage event. When S is represented by (l+m+g), if (l+m+g) <=mic2 (N) +x+y+a), it is indicated that no sound leakage event occurs.
In some embodiments, the electronic device determines a difference between a sum of the loudness of the ambient noise signal, the first difference, the second difference, and the third difference, and a sum of the loudness of the sound source signal and the volume level, as the target volume level, without occurrence of the sound leakage event. That is, G < = mic2 (N) +x+y+a- (l+m), the electronic device determines any gain value satisfying the above formula as the target gain value.
In some embodiments, the method F of adjusting the gain value of the AGC provided by steps 504-506 can be represented as the following formula.
Figure BDA0003232386780000121
That is, when L+M+G is less than or equal to mic2 (N) +Y+X+A, the gain G of the AGC module is set so as not to change accordingly, and when L+M+G > mic2 (N) +Y+X+A, the gain G of the AGC module is required to satisfy G less than or equal to mic2 (N) +Y+X+A-M-L.
