Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

Based on the hardware structure of the equipment, the embodiment of the earphone leakage compensation method is provided.
Referring to fig. 2, in a first embodiment of an earphone leakage compensation method of the present invention, the earphone leakage compensation method includes:
step S10 of detecting an output value of the capacitive sensor, wherein the output value of the capacitive sensor is determined by a bonding area between a wearing portion of the earphone and a human ear;
it should be noted that, the existing earphone only compensates the output signal of the earphone for the external noise, so as to achieve the purpose of active noise reduction, and improve the quality of the sound effect output by the earphone by eliminating the interference of the external noise. The earphone essentially reduces interference signals in actual received signals of human ears, ensures that the signals received by the human ears are all from output signals of the earphone, and further ensures the auditory effect of earphone users. However, in practical use, the wearing part of the earphone is not completely attached to the ears of a person, and because the size and the shape of the earphone are fixed, the sizes and the shapes of the ears of different users of the earphone are different, so that the attachment degree of the earphone to different users is different, a certain amount of leakage of the output signal of the earphone is caused more or less, and if the interference of external noise is only considered to be offset during signal compensation, the leakage of the output signal of the earphone is ignored, and the optimal compensation effect cannot be achieved.
Based on this, the embodiment of the present invention provides an earphone leakage compensation method, which is applied to an earphone, implemented in a terminal device such as a PC or a personal computer, and used for performing leakage compensation on the earphone, where the earphone may be a TWS earphone or a wired bluetooth earphone, and the following application to the TWS earphone is taken as an example. The method can be used for leakage compensation of the earphone independently, can also be used with active noise reduction, and can simultaneously compensate output signals leaked by the earphone on the basis of noise reduction. It will be appreciated that the compensation effect is better when used simultaneously with noise reduction. The wearing portion of the earphone is a portion of the earphone corresponding to the ear canal when the earphone is worn, such as an earplug, and the earplug is hereinafter described as an example of the wearing portion. As shown in fig. 3, fig. 3 is a schematic structural diagram of the earphone in the present embodiment, the earphone includes a handle portion 1, an earplug 2 and a sound outlet 4, and a capacitive sensor 3 is disposed in the earplug 2 for detecting a fitting area of the earplug 2 and a human ear. Specifically, the output value of the capacitance sensor 3 is detected, the output value of the capacitance sensor is determined by the fitting area of the ear plug of the earphone and the human ear, and the leakage amount of the earphone, namely the target leakage amount, can be determined according to the fitting area of the ear plug part of the earphone and the human ear.
It can be known that, since the attaching area between the earplug and the human ear determines the output value of the capacitive sensor, the output value of the capacitive sensor may be positively or negatively correlated with the attaching area. That is, the output value of the capacitance sensor may be increased as the bonding area increases, or may be decreased as the bonding area increases, and is related to the characteristics of the capacitance sensor, and is not particularly limited herein.
Step S20, matching the output value of the capacitance sensor with a preset leakage mapping table, and determining the target leakage of the earphone;
further, the output value of the capacitance sensor 3 is matched with a preset leakage amount mapping table, and the leakage amount of the earphone (hereinafter referred to as a target leakage amount for distinguishing) is determined. The capacitive sensor provided in the earphone may be of a proximity type or a pressure type. Wherein, pressure type capacitive sensor atress produces deformation and leads to the capacitance value sound production to change after the earplug is gone into the ear, can be used for detecting the size of earplug and people's ear contact force to judge the laminating degree of earplug and people's ear. The proximity type capacitive sensor can judge the distance relation between the human ear and the earplug according to the mutual capacitance influence between the earplug and the human ear, and the output size of the proximity type capacitive sensor is only related to the fitting area (namely the contact area) between the human ear and the earplug of the earphone in actual use. The proximity type capacitive sensor can also be used for detecting the in-ear state of the earphone, and only judges the in-ear state of the earphone when the in-ear state is detected, wherein the in-ear state comprises two detection results of in-ear state or out-of-ear state. When the output value of the capacitance sensor is subdivided, the output value of the capacitance sensor can be associated with the leakage state of the earphone, and when the leakage of the earphone changes, the change of the contact area between the human ear and the earplug is proved, and at the moment, the output value of the capacitance sensor also changes. Therefore, when there is a correlation between the output value of the capacitance sensor and the leakage amount of the earphone, the leakage amount of the earphone can be obtained by detecting the output value of the capacitance sensor based on the correlation.
Specifically, after the output value of the capacitive sensor is detected, the output value of the capacitive sensor is matched with a preset leakage mapping table, and the target leakage of the earphone is determined. The leakage mapping table can be obtained through experimental means, based on the correlation among the output value of the capacitance sensor, the attaching area between the earplug and the human ear and the leakage of the earphone, the attaching area between the earplug and the human ear is continuously changed through the experimental means, then the output value of the capacitance sensor and the leakage of the earphone are detected, the corresponding relation between the output value of the capacitance sensor and the leakage of the earphone can be obtained, and the mapping table between the leakage of the earphone and the output value of the capacitance sensor can be established based on the corresponding relation. When the output value of the capacitance sensor is detected, the target leakage amount of the earphone corresponding to the output value of the capacitance sensor can be determined based on the leakage amount mapping table.
It will be appreciated that other types of capacitive sensors may be provided in the ear bud of the headset to achieve the same technical effect, and therefore the type of capacitive sensor is not specifically limited herein.
Further, the refinement of step S20 further includes:
step S201, determining a corresponding relation between the leakage amount of the earphone and the output value of the capacitance sensor according to the leakage amount mapping table;
step S202, calculating the target leakage amount of the earphone based on the corresponding relation and the output value of the capacitance sensor.
When the target leakage amount of the earphone is determined, the output value of the capacitance sensor is matched with a preset leakage amount mapping table, specifically, the corresponding relation between the leakage amount of the earphone and the output value of the capacitance sensor is determined according to the leakage amount mapping table, and the target leakage amount of the earphone is calculated based on the corresponding relation and the output value of the capacitance sensor.
And step S30, performing leakage compensation on the output signal of the earphone according to the target leakage amount.
After the target leakage amount of the earphone is determined, leakage compensation is carried out on the output signal of the earphone according to the target leakage amount, and the specific compensation mode is that a compensation signal which is the same as a signal corresponding to the leakage amount of the earphone is generated and is superposed into the output signal of the earphone to carry out leakage compensation on the output signal of the earphone, so that the signal received by human ears is consistent with the output signal of the earphone.
Further, the refinement of step S30 further includes:
step S301, detecting a target output signal of the earphone, and generating a leakage compensation signal according to the target leakage amount;
step S302, superimposing the leakage compensation signal on the target output signal, and performing leakage compensation on the target output signal.
When leakage compensation is performed on the output signal of the earphone according to the target leakage amount, firstly, the target output signal of the earphone is detected, and a waveform corresponding to the output signal of the earphone is obtained, wherein the target output signal is the output signal which is output by the earphone and is expected to be received by human ears. However, after the target output signal is output by the earphone, in the process of transmitting the target output signal to the ear for receiving, because the earplug is not tightly attached to the ear, the signal output by the earphone is leaked, so that the signal actually received by the ear is inconsistent with the signal output by the earphone, and the auditory effect of a user is affected. Therefore, it is necessary to perform leakage compensation on the output signal of the earphone, and specifically, a leakage compensation signal having the same waveform as that of the target leakage amount of the earphone is generated according to the target leakage amount of the earphone and is superimposed on the output signal of the earphone, so as to perform leakage compensation on the output signal of the earphone.
In the present embodiment, the leakage amount of the earphone is detected by providing a capacitive sensor in the wearing part of the earphone, specifically, the output value of the capacitive sensor is detected, wherein the output value of the capacitive sensor is determined by the fitting area between the wearing part of the earphone and the human ear; matching the output value of the capacitive sensor with a preset leakage mapping table to determine the target leakage of the earphone; and carrying out leakage compensation on the sound effect of the earphone according to the target leakage amount. Confirm the laminating area of earphone and people's ear through capacitive sensor's output value, and then confirm the leakage quantity of earphone output signal, compensate the output signal that people's ear can be received to the leakage quantity of earphone output signal, can guarantee the uniformity of the signal of people's ear actual receipt and earphone self output signal to ensure the audio quality of earphone, promote user's use and experience.
Further, on the basis of the above-mentioned embodiments of the present invention, a second embodiment of the headphone leakage compensation method of the present invention is proposed.
Based on the foregoing embodiment, in this embodiment, the headphone leakage compensation method further includes:
step A10, when detecting that the earphone is in an in-ear state, acquiring an analog output value of a capacitive sensor in the earphone;
in this embodiment, before performing leakage compensation on the output signal of the earphone, a leakage amount mapping table of the earphone needs to be obtained, that is, a corresponding relationship between an output value of the capacitance sensor and a leakage amount of the output signal of the earphone needs to be determined. First, by means of experimental means, when it is detected that the earphone is in an in-ear state in the dummy human ear, an output value of the capacitance sensor (hereinafter referred to as a dummy output value for distinction) is acquired. The simulated human ear used for the experiment may be a human ear model or a human ear satisfying the experimental conditions, and is not limited herein. Taking the human ear model as an example, the detection of whether the earphone is in the in-ear state may be to compare the output value of the capacitive sensor with a preset threshold value through the output value of the capacitive sensor, so as to determine whether the earphone is in the in-ear state, and the acquisition of the output value of the capacitive sensor may be performed once every preset time period, or may be performed when a user triggers a corresponding acquisition instruction, which is not specifically limited herein.
Step A20, detecting the analog leakage quantity of the output signal of the earphone, and storing the analog output value and the analog leakage quantity as a group of test values;
after the output value of the capacitance sensor is obtained, the leakage amount of the earphone under the output value of the capacitance sensor is detected (hereinafter referred to as a simulated leakage amount for distinction), and then the obtained simulated output value of the capacitance sensor and the simulated leakage amount of the earphone are stored as a set of test values.
Further, the refinement of the step a20 further includes:
step B1, detecting first sound effect information received by the simulated human ear by using the sound effect detection device in the simulated human ear;
and step B2, acquiring second sound effect information output by the earphone, comparing the first sound effect information with the second sound effect information, and determining the analog leakage amount of the output signal of the earphone.
A in the simulation people's ear for the experiment, be equipped with sound effect detection device, can be used to detect the audio signal that people's ear received, utilize this sound effect detection device to detect the signal that people's ear received at the receiving end of simulation people's ear and be first sound information promptly, then obtain the output signal of earphone, confirm the second sound information of earphone output according to this output signal, compare the second sound information of the first sound information that will acquire and earphone output, confirm the difference between the output signal of signal and earphone that people's ear received, thereby confirm the leakage quantity of the output signal of earphone.
Step A30, when detecting the analog output value changes, returning and executing the step of detecting the analog leakage amount of the output signal of the earphone until the analog leakage amount does not change any more;
after a group of test values are stored, the attaching area of the ear plug of the earphone and the simulated human ear is adjusted, so that the attaching area of the ear plug of the earphone and the human ear determines the output value of the capacitance sensor, when the capacitance sensor is of an approaching type, the attaching area changes, the output value of the capacitance sensor changes, when the attaching area changes, the pressure of the human ear acting on the ear plug changes, and therefore the output value of the capacitance sensor changes. When the fitting area of the earplug and the human ear changes, the output value of the capacitance sensor changes, and when the output value of the capacitance sensor changes, the analog leakage amount of the corresponding earphone is obtained again and stored. Further, when the fitting area between the earplug and the simulated human ear is adjusted, the adjustment can be from large to small, namely, the fitting area between the earplug and the simulated human ear is gradually reduced from the complete fitting of the earplug and the simulated human ear; or the size of the earplug can be adjusted from small to large, namely, the fitting area between the earplug and the human ear is gradually increased from the state that the earplug is just inserted into the ear until the earplug is completely fitted with the human ear. And detecting the simulated leakage amount of the earphone once under the regulated analog output value of the capacitance sensor every time the fitting area between the earplug and the human ear is regulated, and then storing the leakage amount as a group of test values until the leakage amount of the earphone is not changed any more, thus showing that the earplug of the earphone and the simulated human ear are completely fitted or not contacted at the moment.
Step A40, establishing a leakage mapping table of the earphone according to the stored test value, wherein the leakage mapping table comprises the corresponding relation between the output value of the capacitance sensor and the leakage of the earphone.
And establishing a leakage mapping table of the earphone by using the stored test value, wherein the established leakage mapping table represents the corresponding relation between the output value of the capacitance sensor and the leakage of the earphone, so that the corresponding leakage of the earphone can be obtained when the output value of the capacitance sensor is obtained based on the leakage mapping table.
Further, the refinement of the step a40 further includes:
step C1, fitting the stored test values, and determining the corresponding relation between the simulation output value and the simulation leakage amount;
