Thus, statements such as "in one embodiment", "in some embodiments", "in other some embodiments", "in still other embodiments" etc. that appear in different places in this specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in another way.

[0044] Existing over-ear headphones generally have a pneumatic balance design to avoid the low-frequency air flow impact on the wearer's eardrum caused by the sudden increase in air pressure in the front cavity of the headphone when adjusting or squeezing after wearing the earcups, and can relieve or even avoid the howling caused by the air flow impact on the feedback microphone.
[0045] Currently, the common design method is to use a short - circuit hole structure in combination with a sound - resistance mesh cloth, which enables the air pressure in the front and rear cavities to conduct and balance, but the acoustic low - frequency performance curve will be attenuated compared with that of other structures. However, during the actual wearing process of consumers, since the head shapes and ear contours of each person are different, there are also differences in the sealing conditions between the head - mounted headphones and the human ear, which easily causes sound leakage (mainly low - frequency sound signal leakage). At this time, the short - circuit hole structure loses its original meaning and even makes the subjective sound - listening effect worse.
[0046] Based on this, the embodiments of the present application provide a sound - leakage compensation method, device, equipment, and computer - readable storage medium, which overcome the design defects of the short - circuit hole structure when sound leakage occurs. In the sound - leakage compensation method, first, the current clamping force of the headphone device is obtained; then, according to the current clamping force and a preset threshold, a comparison result is determined; then, according to the comparison result, it is judged whether the headphone device has a sound - leakage phenomenon; if the headphone device has a sound - leakage phenomenon, the sound - transmission area of a preset short - circuit hole is adjusted according to the comparison result to compensate for the sound - leakage phenomenon.
[0047] Thus, the present application uses the clamping force as a judgment basis to obtain the sound - leakage phenomenon when different users wear the headphone device, and makes targeted sound - leakage compensation for this sound - leakage phenomenon by adjusting the sound - transmission area of the preset short - circuit hole in the headphone device, thereby ensuring the sound - listening effect when different users wear the headphone device.
[0048] The sound - leakage compensation method, device, equipment, and computer - readable storage medium provided by the embodiments of the present application will be specifically described through the following embodiments. First, the sound - leakage compensation method in the embodiments of the present application is described.
[0049] The embodiments of the present application provide a sound - leakage compensation method, referring to Figure 1 , Figure 1 which is a schematic flowchart of a sound - leakage compensation method provided by an embodiment of the present application. This sound - leakage compensation method can be applied to headphone devices. As Figure 1 shown, the sound - leakage compensation method provided in this embodiment includes steps S10 to S40.
[0050] Step S10, obtain the current clamping force of the headphone device;
[0051] It should be noted that the headphone device can be a head - mounted headphone. In this embodiment, the current clamping force of the headphone device is set as F. The clamping force is used to control the sealing condition between the earcup and the head of the headphone wearer. The greater the clamping force, the better the sealing condition between the earcup and the head of the headphone wearer, and the lower the probability of sound - leakage phenomenon. On the contrary, the smaller the clamping force, the worse the sealing condition between the earcup and the head of the headphone wearer, and the higher the probability of sound - leakage phenomenon.
[0052] Step S20: Determine the comparison result according to the current clamping force and the preset threshold value;
[0053] In this embodiment, a preset threshold value for evaluating the sealing condition is set for the above-mentioned current clamping force F. By comparing the current clamping force F with the preset threshold value, the comparison result can be obtained, and to a certain extent, the comparison result can reflect the sealing condition between the earphone cup and the head of the earphone wearer.
[0054] In some feasible embodiments, the preset threshold value includes a minimum clamping force and a standard clamping force; the above-mentioned step S20 includes:
[0055] Step S201: When the current clamping force is not less than the standard clamping force, determine that the clamping force meets the standard;
[0056] Step S202: When the current clamping force is less than the minimum clamping force, determine that the clamping force is insufficient;
[0057] Step S203: When the current clamping force is not less than the minimum clamping force and less than the standard clamping force, determine that the clamping force is moderate.
[0058] In this embodiment, two preset threshold values for comparison are set for the current clamping force F, namely the minimum clamping force F min and the standard clamping force F0, where the minimum clamping force F min is less than the standard clamping force F0; when F is not less than F0, it indicates that the clamping force meets the standard, and at this time, the sealing condition between the earphone cup and the wearer's head is better, and the probability of sound leakage is lower; when F is less than F min it indicates that the clamping force is insufficient, and at this time, the sealing condition between the earphone cup and the wearer's head is poor, and the probability of sound leakage is higher; when F is not less than F min and less than F0, it indicates that the clamping force is moderate, and at this time, the sealing condition between the earphone cup and the wearer's head is moderate.
[0059] Step S30: Judge whether there is a sound leakage phenomenon in the headphone device according to the comparison result;
[0060] It should be understood that the sealing condition between the earphone cup and the wearer's head is closely related to whether there is a sound leakage phenomenon in the headphone device. If the sealing condition is good, the probability of sound leakage is lower, and if the sealing condition is poor, the probability of sound leakage is higher.
[0061] In some feasible embodiments, the above-mentioned step S30 includes:
[0062] Step S301, if the comparison result shows that the clamping force meets the standard, it is determined that there is no sound leakage in the headphone device;
[0063] Step S302, if the comparison result shows that the clamping force is insufficient or moderate, it is determined that there is a sound leakage phenomenon in the headphone device.
[0064] In this embodiment, for the convenience of understanding and distinction, the situation where the clamping force meets the standard is directly regarded as no sound leakage phenomenon, and the situation where the clamping force is insufficient or moderate is regarded as having a sound leakage phenomenon; however, in actual applications, there may still be an unobvious sound leakage phenomenon when the clamping force meets the standard, and there may still be no obvious sound leakage phenomenon when the clamping force is moderate. It should be emphasized in this embodiment that when the clamping force is large, the probability of the sound leakage phenomenon occurring is low, and when the clamping force is small, the probability of the sound leakage phenomenon occurring is high.
[0065] Step S40, if so, adjust the sound transmission area of the preset short-circuit hole according to the comparison result to compensate for the sound leakage phenomenon.
[0066] It should be noted that this embodiment can be understood in combination with Figure 2 the partial structural schematic diagram of the headphone device shown, as Figure 2 shown, the headphone device includes a Mic (microphone), a front cavity, a sound outlet hole, an electromagnet 1, a permanent magnet, an electromagnet 2, an ear tip, a speaker front plate, a short-circuit hole structure, a short-circuit hole mesh, a speaker, and a rear cavity; in this embodiment, it is mainly understood in combination with the electromagnet 1, the permanent magnet, the electromagnet 2, and the short-circuit hole structure among them. The preset short-circuit hole is Figure 2 the short-circuit hole structure in
[0067] When the clamping force does not meet the standard, that is, when the clamping force is insufficient or moderate, it is difficult to ensure the sealing condition between the headphone and the human ear. The sound transmission area of the short-circuit hole can be reduced to make a certain compensation for the low-frequency sound signal leakage. It should be noted that blocking the short-circuit hole has a certain compensation effect on the low-frequency sound signal leakage, but when the sound leakage is large, blocking the short-circuit hole can improve the low-frequency performance to a certain extent but cannot completely compensate for the low-frequency performance decline caused by the sound leakage.
[0068] Step S41, adjust the supply current of the preset electromagnet according to the comparison result to change the position of the preset permanent magnet, and then adjust the sound transmission area of the preset short-circuit hole, where the preset permanent magnet is used to block the preset short-circuit hole.
[0069] Similarly, referring toFigure 2 , the preset permanent magnet, namely Figure 2 the permanent magnet marked in Figure 2 . The preset electromagnet can be Figure 2 the electromagnet 1 or electromagnet 2 in Figure 2 . When the headphone device is worn normally, it is regarded as the original state. At this time, the permanent magnet is at the center position of the electromagnet 1 and the electromagnet 2. The magnetic forces of the electromagnet 1 and the electromagnet 2 on the permanent magnet are both repulsive forces. In the original state, the repulsive forces generated by the two are the same in magnitude and opposite in direction. When the clamping force is too small and causes sound leakage, the magnetic property of the electromagnet 1 can be increased by increasing the supply current of the electromagnet 1 or the magnetic property of the electromagnet 2 can be decreased by decreasing the supply current of the electromagnet 2 to make the permanent magnet move to the right to block the short-circuit hole, thereby reducing the sound transmission area of the short-circuit hole and making a certain compensation for the low-frequency performance.
[0070] In some feasible embodiments, the step of adjusting the supply current of the preset electromagnet according to the comparison result to change the position of the preset permanent magnet in the above step S41 includes:
[0071] Step S411, if the comparison result is that the clamping force is insufficient, adjust the supply current of the preset electromagnet to the maximum state so that the preset permanent magnet completely blocks the preset short-circuit hole;
[0072] Step S412, if the comparison result is that the clamping force is moderate, adjust the supply current of the preset electromagnet based on the current clamping force and the standard clamping force so that the preset permanent magnet partially blocks the preset short-circuit hole.
[0073] It should be noted that in this embodiment, the preset electromagnet is described by taking the electromagnet 1 as an example. When the current clamping force F is insufficient, it indicates that the sealing condition between the earcup and the ear of the headphone wearer is poor. At this time, the existence of the short-circuit hole will cause the sound leakage phenomenon to be more serious. Therefore, the repulsive force generated by the electromagnet 1 on the permanent magnet can be increased by increasing the supply current of the electromagnet 1, so that the permanent magnet moves to the right to a position where it completely blocks the short-circuit hole, eliminating the influence of the short-circuit hole on the sound leakage phenomenon; when the current clamping force F is moderate, it indicates that the sealing condition between the earcup and the ear of the headphone wearer is moderate. If the short-circuit hole transmits sound completely, it will still make the sound leakage phenomenon more serious. Therefore, it is necessary to appropriately increase the supply current of the electromagnet 1 according to the gap between the current clamping force F and the standard clamping force F0, thereby increasing the repulsive force generated by the electromagnet 1 on the permanent magnet, so that the permanent magnet moves to the right to a position where it partially blocks the short-circuit hole, offsetting part of the influence of the short-circuit hole on the sound leakage phenomenon.
[0074] In some feasible embodiments, after step S30, the sound leakage compensation method further includes:
[0075] Step A40, if not, do not adjust the sound transmission area of the preset short-circuit hole.
[0076] It should be noted that in this embodiment, if the conclusion based on the comparison result is that there is no sound leakage phenomenon in the earphone device, it means that the design of the short-circuit hole only plays its original role and will not have any impact on the sound leakage phenomenon. Therefore, there is no need to block the short-circuit hole to adjust its sound transmission area.
[0077] In some feasible embodiments, the above step A40 includes:
[0078] Step A401, if the comparison result shows that the clamping force meets the standard, keep the supply current of the preset electromagnet in the original state, so that the preset permanent magnet does not block the preset short-circuit hole.
[0079] It should be understood that the absence of sound leakage in the earphone device corresponds to the comparison result that the clamping force meets the standard. At this time, there is no need to adjust the supply currents of electromagnets 1 and 2, nor to change the position of the permanent magnet. The short-circuit hole does not need to be blocked and is in the state with the largest sound transmission area.
[0080] Exemplarily, in this embodiment, through laboratory standard human heads or actual tests of a large number of consumers, the sound leakage relationship corresponding to different clamping force magnitudes F is obtained. Through laboratory standard human head tests, the improvement relationship of the low-frequency sound performance by increasing the supply current magnitude I1 of electromagnet 1 or decreasing the supply current magnitude I2 of electromagnet 2 (reducing the sound transmission area of the short-circuit hole) is obtained, and the relationship between the current clamping force and the supply current magnitude of the preset electromagnet is obtained. Here, taking the preset electromagnet as electromagnet 1 as an example:
[0081]
[0082] In the above formula, I0 represents the supply current in the original state, and k is a coefficient obtained from the test data. It can be seen from the above formula that when the current clamping force F is not less than F0, it is considered that the earphone is worn normally and there is no sound leakage at this time, and the supply current of electromagnet 1 remains unchanged in its original state (similarly, the supply current of electromagnet 2 remains unchanged in its original state), and the permanent magnet still remains in the central position and does not block the short-circuit hole; when the current clamping force F is less than F min at this time, the sound leakage is relatively large, the supply current of electromagnet 1 is in the maximum state (the corresponding supply current of electromagnet 2 is in the minimum state), and at this time the permanent magnet just completely blocks the short-circuit hole, and the sound transmission area of the short-circuit hole can be regarded as 0; when the current clamping force satisfies F min ≤F<F0, the supply current of electromagnet 1 or 2 will change according to the magnitude of F, and at this time the permanent magnet partially blocks the sound transmission area of the short-circuit hole.
[0083] This embodiment provides a method for compensating for sound leakage, which overcomes the design defects of the short-circuit hole structure when sound leakage occurs. In this embodiment, the clamping force is used as the judgment basis to obtain the sound leakage phenomenon when different users wear the headphone device. By adjusting the sound transmission area of the preset short-circuit hole in the headphone device, targeted sound leakage compensation is made for this sound leakage phenomenon, thereby ensuring the listening effect when different users wear the headphone device.
[0084] In addition, the embodiment of the present application also proposes a sound leakage compensation device, referring to Figure 3 , Figure 3 which is a schematic structural diagram of a sound leakage compensation device provided by an embodiment of the present application. As Figure 3 shown, in this embodiment, the sound leakage compensation device includes: an acquisition module 100, a comparison module 200, a judgment module 300, and an execution module 400.
[0085] The acquisition module 100 is used to acquire the current clamping force of the headphone device;
[0086] The comparison module 200 is used to determine a comparison result according to the current clamping force and a preset threshold;
[0087] The judgment module 300 is used to judge whether the headphone device has a sound leakage phenomenon according to the comparison result;
[0088] The execution module 400 is used to adjust the sound transmission area of the preset short-circuit hole blocked according to the comparison result to compensate for the sound leakage phenomenon when the headphone device has a sound leakage phenomenon.
[0089] In some feasible embodiments, the preset threshold includes a minimum clamping force and a standard clamping force, and the minimum clamping force is less than the standard clamping force;
[0090] The comparison module 200 is further used to determine that the comparison result is that the clamping force meets the standard when the current clamping force is not less than the standard clamping force;
[0091] When the current clamping force is less than the minimum clamping force, the comparison result is that the clamping force is insufficient;
[0092] When the current clamping force is not less than the minimum clamping force and less than the standard clamping force, the comparison result is determined to be that the clamping force is moderate.
[0093] In some feasible embodiments, the judgment module 300 is further used to judge that the headphone device does not have a sound leakage phenomenon when the comparison result is that the clamping force meets the standard;
[0094] When the comparison result indicates insufficient clamping force or moderate clamping force, it is determined that there is a sound leakage phenomenon in the headphone device.
[0095] In some feasible embodiments, the execution module 400 is further configured to adjust the supply current of a preset electromagnet according to the comparison result to change the position of a preset permanent magnet, thereby adjusting the sound transmission area of a preset short-circuit hole, wherein the preset permanent magnet is used to block the preset short-circuit hole.
[0096] In some feasible embodiments, when the comparison result indicates insufficient clamping force, the execution module 400 is further configured to adjust the supply current of the preset electromagnet to the maximum state, so that the preset permanent magnet completely blocks the preset short-circuit hole;
[0097] When the comparison result indicates moderate clamping force, the supply current of the preset electromagnet is adjusted based on the current clamping force and the standard clamping force, so that the preset permanent magnet partially blocks the preset short-circuit hole.
[0098] In some feasible embodiments, when there is no sound leakage phenomenon in the headphone device, the execution module 400 is further configured not to adjust the sound transmission area of the preset short-circuit hole.
[0099] In some feasible embodiments, when the comparison result indicates that the clamping force meets the standard, the execution module 400 is further configured to keep the supply current of the preset electromagnet in the original state, so that the preset permanent magnet does not block the preset short-circuit hole.
