Fig. 1 is a schematic diagram of an application environment of a method for detecting sound leakage of an earphone according to an embodiment of the present invention, where the application environment includes: the bluetooth headset 10 and the wearer A of bluetooth headset 10, bluetooth headset 10 is provided with microphone 11, microphone 11 is used for gathering the mixed sound that contains the sound of revealing of the broadcast sound of bluetooth headset and ambient sound, and will mixed sound turns into digital signal, further by processing unit in the bluetooth headset 10 handles mixed sound sample, thereby confirms whether there is the circumstances that sound leaks in the bluetooth headset.
It should be noted that the method for detecting sound leakage of an earphone provided in the embodiment of the present invention may not be applied to a bluetooth earphone, but may also be applied to other types of earphones, such as a wired earphone, and similarly, the microphone 11 may not be the microphone 11 shown in the drawing, or may be a sound collection device in other shapes, and specifically, may be set according to actual needs, and does not need to be limited by the application scenario.
Specifically, the embodiments of the present invention will be further explained below with reference to the drawings.
Example one
An embodiment of the present invention provides a method for detecting sound leakage of an earphone, which can be applied to a bluetooth earphone 10 in the above application scenario, please refer to fig. 2, which shows a flowchart of the method for detecting sound leakage of an earphone according to the embodiment of the present invention, where the method includes, but is not limited to, the following steps:
step 110: collecting a mixed sound sample by the microphone;
wherein the mixed sound sample contains a leakage sound and an ambient sound of a play sound of the Bluetooth headset. In the embodiment of the invention, firstly, the sound is collected by the microphone arranged on the bluetooth headset, and when the bluetooth headset plays the sound, if the sound leaks, the microphone is close to the bluetooth headset, so that the leaked sound of the played sound of the bluetooth headset can be collected, and meanwhile, the environmental sound of the environment where the current wearer of the bluetooth headset is located can also be collected.
Step 120: acquiring a first waveform of the mixed sound sample and a second waveform of playing sound of the Bluetooth headset;
further, when the mixed sound is collected through the microphone, the microphone converts a sound signal of the mixed sound into an electric signal, so that the mixed sound sample is sent to a processor/controller of the bluetooth headset, and the bluetooth headset acquires a first waveform of the mixed sound sample according to the electric signal. In addition, a second waveform of a sound currently played by the bluetooth headset may also be obtained, where the second waveform may be obtained by identification according to an electrical signal of the played sound, or may be directly obtained through an electronic device connected to the bluetooth headset, such as a mobile phone.
Step 130: judging whether the matching degree of the first waveform and the second waveform is greater than a preset threshold value or not; if yes, go to step 140; if not, go to step 150.
In the embodiment of the present invention, because the leakage sound of the played sound of the bluetooth headset usually has little influence on the environment in a busy place, at this time, the environmental sound in the busy environment is inevitably more and noisier than the leakage sound, the occupancy of the environmental sound in the mixed sound is higher, and at this time, if the first waveform and the second waveform are compared, the similarity/matching degree between the two waveforms is lower. In a quiet scene, the leakage sound of the playing sound of the bluetooth headset generally has a large influence on the environment, at this time, the proportion of the environment sound in the mixed sound in the quiet environment is low, the proportion of the leakage sound of the playing sound of the bluetooth headset in the mixed sound is high, and at this time, if the first waveform and the second waveform are compared, the similarity/matching degree of the two waveforms is high. Based on the above, a preset threshold may be set, and whether the sound leakage of the bluetooth headset occurs or not may be determined by comparing whether the matching degree of the first waveform and the second waveform is greater than the preset threshold.
Step 140: and determining that the Bluetooth headset has sound leakage.
In the embodiment of the present invention, if the matching degree of the first waveform and the second waveform is greater than the preset threshold, it may be determined that the bluetooth headset has a sound leakage condition, and in this case, the audio content played by the bluetooth headset may be heard by other people existing in the current environment, so as to affect the other people and cause interference to the other people.
Step 150: and determining that the Bluetooth headset does not have the condition of sound leakage or the volume of the leaked sound is not large.
In the embodiment of the present invention, if the matching degree of the first waveform and the second waveform is smaller than the preset threshold, a situation may be that the bluetooth headset does not leak sound; in another case, it may also be that the sound leaked from the bluetooth headset may not affect other people in the environment because the bluetooth headset is located in a noisy and busy environment.
Further, in some embodiments, please refer to fig. 3 together, which illustrates a flow of another method for detecting sound leakage of an earphone according to an embodiment of the present invention, and as shown in fig. 3, before the step 130, the method further includes:
step 161: setting a volume level of the ambient sound;
wherein the volume level and the volume level of the environmental sound are in a positive correlation mapping relation. In this embodiment of the present invention, before the step of determining whether the matching degree of the first waveform and the second waveform is greater than the preset threshold, the volume level of the environmental sound may be preset. For example, the volume decibel range that can be detected in real life in a generally quiet environment such as a library is set to a low volume level, the volume decibel range that can be detected in real life in a somewhat loud environment such as a cafe, which typically has a portion of human voice, is set to a medium volume level, and the volume decibel range that can be detected in real life in a generally noisy environment such as a pub or a vegetable market is set to a high volume level.
Step 162: closing the Bluetooth headset for a preset time period to collect the ambient sound;
further, in order to acquire the current actual noisy situation of the environment where the wearer of the bluetooth headset is located, the bluetooth headset may be closed for a period of time to acquire the environmental sound, and the step of closing the bluetooth headset to acquire the environmental sound may be performed automatically by the bluetooth headset or may be performed by manual control of a user. Preferably, when the automatic operation is performed, the bluetooth headset may be set to turn off and collect the mixed sound when the bluetooth headset detects a large change of the mixed sound, that is, when the environment is switched normally, or may be set to detect at regular time. Or, the collection of the environmental sound can be performed when the user makes a gesture action or selects on the electronic device connected with the Bluetooth headset by default.
Step 163: judging the volume level of the environmental sound according to the volume of the environmental sound;
after collecting ambient sound, according to present ambient sound's volume size, judge ambient sound's volume level to can confirm currently the wearer is in what kind of environment, how the noisy degree of current environment is.
Step 164: and setting the preset threshold according to the volume level.
And the volume level and the preset threshold value are in a mapping relation of negative correlation. In an embodiment of the present invention, after determining the volume level of the ambient sound, the preset threshold may be set according to the volume level.
For example, as an example of step 161, when the volume level is determined to be high, it may be determined that the environment sound is loud in a noisy environment, and the sound leaked from the earphone usually hardly covers the environment sound, and the proportion of the leaked sound in the mixed sound is usually hard to reach a high value, but the sound leaked from the earphone still may affect people around, so the preset threshold may be set to be small, for example, about fifty percent, and when the matching degree of the first waveform and the second waveform is determined to be over fifty percent, it is determined that the sound leakage of the bluetooth earphone exists.
Alternatively, when the volume level is determined to be low, it may be determined that the environment sound is low in a quieter environment, and the sound leaked from the earphone easily covers the environment sound, and the proportion of the leaked sound in the mixed sound is generally easy to reach a high value, but the leaked sound is not necessarily large and does not necessarily affect people around, so that the preset threshold may be set to be large, for example, ninety percent or so, and when the matching degree of the first waveform and the second waveform is determined to exceed ninety percent, it may be determined that the sound leakage of the bluetooth earphone exists.
Further, in some embodiments, please refer to fig. 4 together, which illustrates a flow of another method for detecting sound leakage of an earphone according to an embodiment of the present invention, and as shown in fig. 4, after the step 140, the method further includes:
step 170: and outputting a notification signal that the sound of the Bluetooth headset leaks.
Wherein the notification signal is a vibration signal and/or a voice signal. In the embodiment of the present invention, after the step of determining that the sound leakage exists in the bluetooth headset, a notification signal may be output, so that a wearer of the bluetooth headset knows that the sound leakage exists in the bluetooth headset and may affect surrounding people, and meanwhile, the bluetooth headset may be used as a next bluetooth headset to perform corresponding operations to reduce an early warning about the impact caused by the sound leakage. Specifically, the vibration of the vibration motor arranged in the bluetooth headset can be used for reminding the wearer, or the broadcast voice can be used for informing the wearer, specifically, the vibration motor can be arranged according to actual needs, and the limitation of the embodiment of the invention is not required.
Further, in some embodiments, please refer to fig. 5 together, which illustrates a flow of another method for detecting sound leakage of an earphone according to an embodiment of the present invention, and as shown in fig. 5, after the step 140, the method further includes:
step 180: and reducing the volume of the Bluetooth headset.
In the embodiment of the present invention, after the step of determining that the sound leakage exists in the bluetooth headset, the volume of the bluetooth headset may be reduced to reduce the influence of the sound leakage, so as to avoid the influence of the sound leakage on the work or rest of other people around the bluetooth headset.
Further, in some embodiments, please refer to fig. 6 together, which illustrates a flow of another method for detecting sound leakage of an earphone according to an embodiment of the present invention, and as shown in fig. 6, before the step 180, the method further includes:
step 191: detecting whether a person exists in a preset range around a wearer of the Bluetooth headset through an infrared sensor and/or a human body sensor; if yes, jumping to step 180; if not, go to step 192.
Step 192: and the volume of the Bluetooth headset is not adjusted.
In the embodiment of the present invention, since background music is played in a general store in a place such as a bar or a cafe, the background music may cause loud ambient sound, however, if there is no person in the public place, there is no situation that the leaked earphone sound may affect the person, therefore, before the step of reducing the volume of the bluetooth earphone, it may be further detected whether there is a person in a preset range around the wearer of the bluetooth earphone, if yes, the step of reducing the volume of the bluetooth earphone is skipped, and if no, the volume of the bluetooth earphone may not be adjusted.
Wherein, the preset range can be set according to the actual situation. Preferably, the preset range may be set according to the environment in combination with the volume level of the environmental sound obtained in step 163, and in a quiet environment, the preset range may be set to be larger, for example, a circle range with a radius of one meter around the wearer of the bluetooth headset is set as the preset range; in a noisy environment, a small range may be set, for example, a circle range of a half meter radius around the wearer of the bluetooth headset is set as the preset range, and in particular, the setting may be performed according to actual needs, and the limitation of the embodiment of the present invention is not required.
Further, in some embodiments, please refer to fig. 7 together, which illustrates a sub-flow of step 180 in the method of fig. 5 or fig. 6, wherein the step 180 further includes:
step 181: calculating a difference value between the matching degree and the preset threshold value;
step 182: and controlling the volume of the Bluetooth headset to be reduced step by step according to the difference until the matching degree of the first waveform and the second waveform is lower than the preset threshold.
In the embodiment of the present invention, before the step of reducing the volume of the bluetooth headset, a difference between the matching degree and the preset threshold may be calculated, the difference value can be used for determining the influence degree of the current leaked sound of the Bluetooth headset on the environment, and controlling the volume of the Bluetooth headset to be reduced step by step according to the difference value, wherein the mixed sound is collected again when the volume is reduced each time, re-acquiring the first waveform and the second waveform, and re-comparing the matching degree of the first waveform and the second waveform after the volume of the earphone is reduced with the preset threshold value until the matching degree of the first waveform and the second waveform is lower than the preset threshold value, therefore, the volume of the Bluetooth headset can be properly adjusted, the phenomenon that the user experience is influenced by too low volume adjustment is avoided, or the volume is still high and can interfere other people in the environment.
Wherein, control the step that bluetooth headset's volume reduces step by step further includes: and when receiving the gesture action made by the wearer of the Bluetooth headset, reducing the volume of the Bluetooth headset. That is to say, in the embodiment of the present invention, the step of reducing the volume of the bluetooth headset may be automatically controlled by the bluetooth headset, or the step of reducing the volume of the bluetooth headset may also be handed over to the user, and when the user knows that the current bluetooth headset leaks sound seriously through the notification signal, and needs to reduce the volume, the user may control the bluetooth headset to reduce the volume through a gesture action. Specifically, the gesture may be acquired through a touch area or a button of the bluetooth headset, or may be acquired through a sensor, such as an infrared sensor or a human body sensor, disposed on the bluetooth headset.
