First embodiment
Fig. 1 is a schematic structural diagram of an earphone to which the present embodiment is applied. Referring to fig. 1, the present embodiment provides an earphone 10, the earphone 10 including a capacitance part 101, a speaker 102, and a microphone 103.
The capacitance part 101 can form a capacitance. The capacitive part 101 may in particular be a metal sheet of the earphone 10, such as a metal sheet arranged on top of the earphone or in an ear cup. When the earphone 10 is worn, the capacitance value of the capacitance part 101 changes; the capacitance value is a capacitance value between the capacitance part 101 and the human body.
The horn 102 is used to convert electrical signals into sound. The horn 102 may also be referred to as a speaker.
The microphone 103 is used to convert a sound signal into an electrical signal, and can receive sound. The microphone 103 may be specifically an inner microphone disposed on an ear cup of the earphone 10, or may be an active noise reduction earphone feedback microphone, which is not limited to this embodiment.
The embodiment also provides a wearing state detection method of the earphone, which is used for detecting the wearing state of the earphone; wherein the wearing state includes worn and unworn. Fig. 2 shows a schematic flowchart of the wearing state detection method of the earphone provided in the present embodiment, which can be applied to the above-described earphone 10 by way of example and not limitation.
The method provided by the embodiment comprises the steps of A1 to A3.
And A1, determining a first wearing state of the earphone according to the received sound.
Referring to fig. 1, during use of the earphone, the earphone 10 plays sound, specifically, sound (or sound waves) through the speaker 102, such as a ring tone. The microphone 103 (e.g., an inner microphone or a feedback microphone) of the earphone 10 is disposed inside the earmuff in the same cavity as the horn 102. The sound emitted by the loudspeaker 102 may be transferred to the microphone 103, whether or not the earphone is in a worn state. However, the earphone 10 may vary greatly between an unworn state in which the speaker 102 and the microphone 103 are located and a worn state in which the speaker 102 and the microphone 103 are located in a closed cavity.
The transfer function from the loudspeaker 102 to the microphone 103 is greatly different between the worn state and the unworn state of the earphone, and particularly, after the earphone is worn in a low-frequency area, the transfer function is enhanced obviously, so that whether the earphone is in the worn state or not can be judged by analyzing the transfer function of the current system. For the case of playing a starting ring tone, the first wearing state refers to the wearing state of the earphone 10 when starting up; in other embodiments, the first wearing state may also be a wearing state of the earphone 10 after being turned on.
During use of the earphone, the horn 102 emits sound waves, which are received by the microphone 103 (and the corresponding feedback microphone if an active noise reducing earphone) located in the earmuff. By analyzing the output signal (also referred to as first data) of the earphone and the receiving signal (also referred to as second data) of the microphone, it is possible to determine whether the earphone is currently in a worn state. Fig. 3 is a flowchart of step A1 of the method for detecting a wearing state of an earphone according to the present embodiment. Referring to fig. 3, in the present embodiment, step A1 (determining the first wearing state of the headphone from the received sound) includes steps a11 to a13.
And step A11, obtaining a first transfer function by analyzing the played first data and the second data recorded by the microphone.
During the operation of the earphone 10, the earphone 10 plays first data, which is, for example, audio data of a starting bell sound, through the loudspeaker 102; the microphone 103 simultaneously captures the sound (the power-on bell sound) played by the loudspeaker 102, and obtains second data. By analyzing the first data played by the loudspeaker 102 and the second data collected by the microphone 103, a first transfer function from the loudspeaker 102 to the microphone 103 can be obtained.
And step A12, comparing the first transfer function with a first preset transfer function to obtain contrast.
The aforementioned first transfer function is a transfer function obtained by real-time measurement. The earphone 10 is preset with a specified transfer function corresponding to a wearing state of the earphone 10, such as a worn state or an unworn state; the specified transfer function of the earphone in the worn state or the unworn state can be tested in advance in the development process and saved. The specified transfer function preset by the earphone 10 is a first preset transfer function. And comparing the first transfer function with a first preset transfer function to obtain the contrast ratio.
And step A13, determining a first wearing state of the earphone according to the contrast.
After the contrast is obtained, determining a first wearing state of the earphone according to the contrast, wherein the first wearing state can be worn or not worn. Specifically, if the contrast meets a first condition, for example, the contrast is greater than a first threshold, the first wearing state is determined to be the worn state. If the contrast meets a second condition, such as being less than or equal to a first threshold, the first wearing state is determined to be an unworn state.
In some embodiments, after the current wearing state of the earphone is obtained, the earphone may perform motion control according to the current wearing state, such as pausing music playing or turning off a heart rate sensor.
And A2, acquiring a reference capacitance value corresponding to the first wearing state.
As previously described, for current headphones (such as active noise reduction headphones), an acoustic scheme may be used to detect whether the headphone is in a worn state. The earphone records the sound in the earmuff in real time through the microphone to obtain second data, and analyzes the transfer function under the current wearing scene by matching with the playing audio data (first data) of the loudspeaker, so that whether the current earphone is in a wearing state or not can be detected. However, the scheme requires that the loudspeaker of the earphone is in a playing state so as to detect the wearing state; this method will not detect when the headset is not in a sound producing state (e.g. the user pauses music) or the volume is very low. Therefore, the method provided by the embodiment combines the capacitive sensing technology to detect the wearing state of the earphone, and can detect the wearing state of the earphone under the condition that the earphone is not in a sounding state or the volume is extremely low.
As described above, the earphone 10 is provided with the capacitance part 101 capable of forming a capacitance, and when the earphone is worn or taken off, the capacitance value of the capacitance part 101 is changed significantly, so that the behavior of the user can be judged, and the wearing state of the earphone can be judged; the scheme has the advantages of high sensitivity and extremely low power consumption; however, since the capacitance value of the capacitive component 101 varies significantly with humidity and temperature, a reference threshold cannot be determined to determine wearing and taking off before shipment, which requires the user to start up the earphone in an unworn state, but this causes inconvenience to the user. For this purpose, after determining a first wearing state of the earphone, a reference capacitance value corresponding to the first wearing state is acquired; in this embodiment, the reference capacitance value is the capacitance value of the capacitive component 101 when the earphone is turned on, and since the first wearing state of the earphone is determined, that is, the wearing state or the unworn state of the earphone 10 at the moment of turning on the earphone is determined, the wearing state (for example, the worn or unworn state) of the earphone corresponding to the reference capacitance value is determined.
And A3, determining a second wearing state of the earphone according to the reference capacitance value and the detected capacitance value of the capacitance component.
As described above, the wearing state (such as worn or unworn) of the earphone corresponding to the reference capacitance value is determined, and when the earphone is worn or taken off, the capacitance value between the capacitance part 101 and the human body changes significantly, and the wearing state of the earphone at this time can be determined according to the change; since the wearing state of the earphone is determined based on the reference capacitance value and the detected capacitance value of the capacitance component (the capacitance value is a real-time capacitance value of the capacitance component) after the power-on, the wearing state is regarded as the second wearing state.
For example, a capacitance difference between the reference capacitance value and the capacitance value of the capacitive component 101 is calculated, where the capacitance difference is an absolute value, and the second wearing state of the earphone is determined according to the capacitance difference. Specifically, if the capacitance difference meets a fourth condition, for example, is greater than a specified value, the second wearing state is determined to be a worn state, otherwise (less than or equal to the specified value), the second wearing state is determined to be an unworn state. In this way, a second wearing state of the headset may be determined.
As can be seen from the above, the earphone 10 includes a capacitive part 11 capable of forming a capacitance, and determines a first wearing state of the earphone according to received sounds; acquiring a reference capacitance value corresponding to a first wearing state; the second wearing state of the earphone can be determined in real time through the capacitance sensing technology according to the reference capacitance value and the real-time capacitance value of the capacitor. Therefore, under the condition that the earphone is in any wearing state, the wearing state (namely the first wearing state) of the earphone can be determined according to received sound, then the reference capacitance value corresponding to the first wearing state is obtained, the wearing state of the earphone can be detected by adopting the capacitance sensing technology with extremely low power consumption based on the reference capacitance value, the earphone is allowed to be started up under the condition that the earphone is in any wearing state, and the earphone is convenient to use. The working state of the earphone can be further controlled according to the wearing state, and the user experience can be improved.
Second embodiment
Fig. 4 is a flowchart of step A1 of the method for detecting the wearing state of the earphone according to the present embodiment. Referring to fig. 4, in the present embodiment, step A1 (determining the first wearing state of the earphone from the received sound) further includes steps a11, a12, B14, and B13.
The details of step a11 and step a12 are the same as those of the first embodiment.
And step B14, carrying out correlation analysis on the first data and the second data to obtain correlation.
As described above, the first data is audio data played by the speaker 102, and the second data is second data obtained by the microphone 103 recording sound played by the speaker 102. And carrying out correlation analysis on the first data and the second data to obtain correlation. The correlation analysis is a mature technology for analyzing the similarity of the first data and the second data.
And step B13, determining a first wearing state of the earphone according to the contrast and the correlation.
Specifically, if the contrast ratio (obtained by comparing the first transfer function with the first preset transfer function) meets the first condition and the correlation meets a third condition (for example, when the correlation is higher than a set threshold), determining that the first wearing state is a worn state, otherwise, determining that the first wearing state is an unworn state; the first wearing state is determined to be the unworn state when the contrast meets the first condition but the correlation does not meet the third condition, or when the contrast meets the second condition but the correlation meets the third condition. It should be appreciated that in the case of less noise, the correlation is in accordance with the third condition (i.e., the first data and the second data are correlated); if the correlation does not meet the third condition, the current detection of the earphone (such as measuring the first transfer function) is influenced by stronger external noise, namely the earphone is in an unworn state; if the contrast satisfies the second condition, the first wearing state is determined to be the unworn state as described above. Then, the earphone performs an operation in the worn state or the unworn state.
Therefore, the false detection caused by the interference of the external environment, such as noise, can be prevented, the influence of the external noise on the measurement of the transfer function can be eliminated, and the detection accuracy can be ensured.
Third embodiment
Fig. 5 is a flowchart of a method for detecting a wearing state of an earphone according to the present embodiment. Referring to fig. 5, the method provided in this embodiment further includes step A4.
And A4, determining a third wearing state of the earphone according to the first wearing state and the second wearing state.
After the earphone is started, in the process of playing music, the microphone 103 is used for simultaneously recording audio data (also called first data) played by the loudspeaker 102 to obtain second data; calculating a first transfer function from the loudspeaker 102 to the microphone 103 at the moment according to the first data and the second data; comparing the first transfer function with a preset transfer function (namely, a first preset transfer function) to obtain contrast, wherein the contrast represents the consistency of the two transfer functions; as described above, the first wearing state of the earphone is determined according to the contrast ratio, and specifically, if the contrast ratio meets the first condition, the first wearing state is determined to be the worn state; and if the contrast meets the second condition, determining that the first wearing state is an unworn state.
In the process of playing music after the earphone is powered on, the current wearing state of the earphone is detected by the capacitive sensing technology at the same time, specifically, the second wearing state of the earphone 10 is determined according to the reference capacitance value and the detected capacitance value of the capacitive component 11 as in the aforementioned step A3. The second wearing state at this time is the wearing state when music is played after the earphone is started.
According to the above, after the earphone is turned on, the third wearing state (may be referred to as the current wearing state) of the earphone is determined according to the first wearing state and the second wearing state, where the second wearing state is determined according to the reference capacitance value and the capacitance value of the capacitive component, the first wearing state is determined according to the received sound after the earphone is turned on, and the detection situation of the two wearing states (the first wearing state and the second wearing state) is integrated, so that more accurate state change of the earphone can be obtained, and more accurate state detection can be achieved.
The wearing state of the earphone is detected by adopting the capacitance sensing technology, and when the earphone is started, the capacitance value of the capacitance component 101 is detected inaccurately, so that whether the earphone is in the wearing state at the moment cannot be judged, and the capacitance sensing technology mode is inaccurate in detection when the earphone is started. According to the embodiment of the application, the starting ring tone is played when the earphone is started, the wearing state of the earphone is detected through an acoustic scheme, and the capacitance value at the moment is set to be a corresponding reference capacitance value according to the wearing state obtained by the acoustic detection technology. Specifically, the transfer function is tested for the correct wearing posture of the earphone and stored as a preset designated transfer function (the first preset transfer function), and when the earphone is started up each time, whether the transfer function of the ring tone of the earphone (the first transfer function) is consistent with the first preset transfer function or not is compared; if the capacitance values are consistent, recording the capacitance value of the current capacitance component 101 as a reference capacitance value for the wearing state; in this way, the capacitance value is corrected by the acoustic wave detection, the capacitance value of the capacitive component 101 at the moment when the earphone is started is taken as a reference, and then the real-time change of the capacitance value of the capacitive component 101 is judged based on the reference to determine the wearing or taking-off behavior of the earphone.
The embodiment of the application combines the sound wave and the capacitance sensing technology to detect the wearing state of the earphone, adopts a mode of combining a sound field with the capacitance sensing technology to detect the wearing state of the earphone when the loudspeaker 102 sounds, and uses the capacitance sensing technology to detect the wearing state of the earphone when the earphone does not sound. Because the earphone plays the starting bell sound (such as the prompt tone) at the starting moment, whether the current earphone is in a wearing state or not can be detected through sound waves at the starting moment, and the problem that the wearing state cannot be detected when the earphone is started in a capacitive sensing mode can be effectively solved.
