[0002] Currently, scenarios such as aviation and high-rise elevator operation have become an integral part of people's daily lives and travel. For example, during takeoff and landing, the cabin air pressure can fluctuate significantly within a short period of time. Similarly, during rapid ascent and descent in a high-rise elevator, the cabin air pressure can also fluctuate rapidly.

[0003] In these rapidly changing air pressure scenarios, the physiological structure of the human ear faces severe challenges. Because the atmospheric pressure difference between the inside and outside of the ear cannot be balanced in time, a pressure difference forms between the inside and outside of the eardrum, causing severe tinnitus and ear pain.

[0076] Example 1

[0077] Please refer to Figure 1 The present invention provides a method for adaptively adjusting ear pressure, which is particularly suitable for wearable devices such as in-ear TWS headphones. This solution dynamically adjusts the operating parameters of the ear pressure adjustment component by detecting the difference between ambient air pressure and air pressure in the ear canal in real time to balance the pressure difference inside and outside the ear canal, thereby alleviating tinnitus or ear discomfort caused by rapid changes in air pressure, such as when riding in an airplane or elevator.

[0078] Specifically, the method is applied to a wearable device including an in-ear portion 100 and an earphone body 200 , wherein the in-ear portion 100 is provided with an adjustment mechanism 120 for adjusting the air pressure in the ear.

[0079] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the adaptive ear pressure adjustment system provided in an embodiment of the present application, comprising an in-ear portion 100 and an earphone body 200. The in-ear portion 100 includes an earplug 110 and an adjustment mechanism 120, which comprises a second air pressure sensor, an air pressure chamber, a servo motor, and an air pressure diaphragm piston. The earphone body 200 includes a first air pressure sensor 210 and a control unit. The adjustment mechanism 120 and earphone body 200 are connected via a hot-swappable assembly 300.

[0080] In an optional embodiment, the earplug 110 is made of liquid silicone rubber (LSR) or polyurethane foam and has a hollow design, forming an air chamber. The air chamber is sealed to the earplug 110 via a metal sealing ring to ensure airtightness. A second air pressure sensor is located within the air chamber to monitor the air pressure in the ear canal in real time. The servo motor is connected to the air diaphragm piston via a drive screw. Its forward and reverse rotation drives the piston axially to change the volume of the air chamber, thereby regulating the air pressure in the ear canal.

[0081] The first air pressure sensor 210 of the earphone body 200 is used to detect the ambient air pressure in real time. The control unit 220, integrated into the earphone's main control chip, includes an air pressure analysis module 221, a feature matching module 222, and an adjustment control module 223. The hot-swap assembly 300 physically connects the adjustment mechanism 120 to the earphone body 200 and provides power, thereby supporting the hot-swap functionality of the adjustment mechanism 120.

[0082] Figure 2 、 Figure 3 These are all flow charts of the method for adaptively adjusting ear pressure provided by the embodiments of the present application. The specific steps are as follows:

[0083] Methods include:

[0084] S0, ear pressure automatic adjustment mode is on.

[0085] The connection status of the adjustment mechanism 120 is determined in real time through the GPIO pin level status and hardware edge interrupt signal of the hot-swappable component; when it is detected that the adjustment mechanism 120 is connected, the control unit turns on the automatic ear pressure adjustment mode and performs an initialization calibration operation. The initialization calibration operation includes recording the current error value of the first air pressure sensor 210 and the second air pressure sensor as a subsequent error calibration value, performing relevant software initialization, and controlling the motor to push the piston to reset.

[0086] When it is detected that the adjustment mechanism 120 is disconnected, the automatic ear pressure adjustment mode is turned off.

[0087] S1. In the ear pressure automatic adjustment mode, collect the ambient air pressure value and the ear canal air pressure value.

[0088] In this step, the ambient air pressure value and the ear canal air pressure value are collected at preset time intervals, for example, once per second.

[0089] S2. Analyze the ambient air pressure value and the air pressure value in the ear canal to determine whether the preset ear pressure adjustment conditions are met.

[0090] Please refer to Figure 4Specifically, in this step, the ambient air pressure value and the air pressure value in the ear canal are analyzed to determine whether the preset ear pressure adjustment conditions are met, including:

[0091] S21, calculating the pressure difference between the air pressure in the ear canal and the ambient air pressure, and determining whether the pressure difference is greater than a preset first threshold;

[0092] S22. When the air pressure difference is greater than a preset first threshold, the preset ear pressure adjustment condition is met.

[0093] When calculating the pressure difference between the ear canal pressure value and the ambient pressure value, the ambient pressure value and the ear canal pressure value are first filtered using an exponential moving average filtering algorithm based on the following formula. In this embodiment, the software filtering algorithm uses an exponential moving average (EMA) filter, which gives higher weight to recent data. The formula is:

[0094] y[n]=α·x[n]+(1−α)·y[n−1];

[0095] α is the smoothing factor, 0<α<1; x[n] is the nth data point of the input signal, y[n−1] is the previous filtered output value, and y[n] is the nth data point of the filtered output signal.

[0096] The filtered ambient pressure output is then used as the target pressure, and the filtered ear canal pressure output is used as the current ear pressure. The pressure difference ΔP between the target and current ear pressure values ​​is calculated. If the absolute value of ΔP exceeds a preset threshold (e.g., 5hPa), the preset ear pressure adjustment condition is met, triggering the ear pressure adjustment process. Otherwise, continuous monitoring is initiated.

[0097] This step uses EMA filtering to ensure a smooth voltage regulation process.

[0098] In an optional embodiment, the difference threshold between the target air pressure value and the current ear pressure value is defined as 5 hPa. This value is obtained based on the following data to adapt to most people:

[0099] The sensitivity of the human body to changes in air pressure varies from person to person, and the speed of the change is also important. Generally, the intensity of the change includes the following:

[0100] Slight changes (5-10 hPa): Most people will not feel any noticeable changes, but sensitive people may experience mild headaches, fatigue or joint discomfort.

[0101] Moderate changes (10-20 hPa): More people may experience discomfort, such as headaches, dizziness, tiredness, or mood swings;

[0102] Large changes (above 20 hPa): May have significant impacts on health, such as aggravating symptoms of chronic diseases (such as migraines and arthritis) and even causing cardiovascular problems.

[0103] S3. When the preset ear pressure adjustment conditions are met, the adjustment mechanism 120 is controlled to work according to the preset ear pressure adjustment level based on the pressure adjustment rate curve corresponding to the ear pressure adjustment level, so that the air pressure value in the ear canal approaches the ambient air pressure value at a dynamically adjusted rate.

[0104] In this step, gear parameters are used to match different user groups to alleviate the discomfort of sensitive people.

[0105] Specifically, step S3 further includes: obtaining an ear pressure adjustment level corresponding to the current user;

[0106] The obtained ear pressure adjustment gear position is set as the preset ear pressure adjustment gear position.

[0107] When obtaining the ear pressure adjustment level corresponding to the current user, first obtain the individual characteristic information of the current user; the individual characteristic information includes one or more of age range, gender, body mass index and height;

[0108] Individual characteristic information is input into a preset adjustment level mapping model, which outputs the corresponding ear pressure adjustment level. The adjustment level mapping model is trained based on experimental data from multiple sets of individual characteristics and ear canal pressure tolerance. Furthermore, in actual use, the level parameters are stored in the cloud or on a mobile app and transmitted to the headset locally via Bluetooth.

[0109] Furthermore, in step S3, the adjustment mechanism 120 is controlled to operate according to the ear pressure automatic adjustment algorithm and the pressure adjustment rate curve corresponding to the ear pressure adjustment gear.

[0110] Specifically, the pressure regulation rate curve is dynamically adjusted according to the absolute value of the air pressure difference.

[0111] Specifically, when dynamically adjusting the pressure regulation rate curve, when the pressure difference is greater than the second threshold, a piecewise linear acceleration strategy is adopted based on the interval in which ΔP is located, so that the pressure regulation rate is dynamically adjusted with the parameters corresponding to the interval in which the pressure difference ΔP is located, that is, the pressure regulation rate gradually increases or decreases over time.

[0112] Among them, the piecewise linear acceleration strategy is implemented based on the piecewise linear function, and the piecewise linear function expression is:

[0113]

[0114] Where: x is the pressure difference ΔP between the air pressure in the ear canal and the ambient air pressure;

[0115] f(x) is the adjustment amount calculated based on the input air pressure difference x, which is the expected adjustment rate of the air pressure chamber. It can be understood that, in fact, the expected adjustment rate of the air pressure chamber is different from the adjustment speed of the human body within the range of ΔP.

[0116] a1,a2,…,a n is the slope of each linear function, corresponding to the regulation rate gain of the interval where the pressure difference ΔP is located;

[0117] b1,b2,…,b n is the intercept of each linear function, corresponding to the basic regulation rate of the interval where the pressure difference ΔP is located;

[0118] c1,c2,…,c n is a segmentation point, each segmentation point is used to divide the range of the air pressure difference x into n intervals, for example, it can be divided into [0hPa, 5hPa], [5hPa, 20hPa], [20hPa, 35hPa], ... and so on.

[0119] For example, according to the absolute value of the pressure difference ΔP, a piecewise linear acceleration strategy is used to control the operation of the micro motor 140, including:

[0120] When ΔP>25hPa, the pressure regulation curve with slope a1 is used to achieve rapid regulation;

[0121] When 20hPa<ΔP≤25hPa, the pressure regulation curve with slope a2 is adopted to achieve rapid regulation;

[0122] When 15hPa<ΔP≤20hPa, the pressure regulation curve with slope a3 is used to achieve medium rate regulation;

[0123] When 10hPa<ΔP≤15hPa, the pressure regulation curve with slope a4 is adopted to achieve smooth regulation;

[0124] When 5hPa<ΔP≤10hPa, the pressure regulation curve with slope a5 is adopted to achieve low-speed regulation;

[0125] When ΔP ≤ 5 hPa, that is, when the absolute value of the pressure difference is less than the third threshold, a smooth adjustment strategy is adopted (the slope a6 approaches 0) to maintain a steady state.

[0126] It is understandable that the above description is an example. In actual application, different ΔP intervals correspond to different a n and b n There are n sets of parameters, which are not limited to the above examples.

[0127] Among them, the slopes a1, a2, ..., a nIts value is determined based on the mapping relationship between the pressure difference ΔP between the inside and outside of the human middle ear and the middle ear's own adjustment speed; this mapping relationship is obtained by collecting the time required for the natural balance of the middle ear air pressure under different ΔP through clinical experiments, and calculating the slope value of each interval in the piecewise function, so that the adjustment rate of the air pressure chamber matches the physiological characteristics of the middle ear.

[0128] In this embodiment, the purpose of the aforementioned ear pressure regulation is to stabilize the pressure difference between the inside and outside of the middle ear within 5 hPa.

[0129] Furthermore, the method for adaptively adjusting ear pressure also includes:

[0130] Continuously obtain the current ambient air pressure value and the current ear pressure value, and combine the previous round of target air pressure value and air pressure difference threshold to adjust the ear pressure regulation strategy in real time and perform automatic pressure control.

[0131] In this step, the latest air pressure data is continuously collected, and the pressure adjustment rate is dynamically optimized in combination with the results of the previous round of adjustment until the pressure difference ΔP is less than the threshold and the air pressure inside and outside the ear canal tends to be balanced, thereby achieving the purpose of real-time feedback and iterative adjustment.

[0132] It is understood that individual characteristic information can be input by the user through the mobile phone APP, and the APP retrieves the matching gear parameters from the cloud and sends them to the earphones. If the user does not customize the gear, the factory default parameters are used.

[0133] Example 2

[0134] Please refer again Figure 1 , and combined with reference Figure 5 Based on the above embodiments, an embodiment of the present invention provides a system for adaptively adjusting ear pressure, which is used to implement the method for adaptively adjusting ear pressure in the above embodiments, including:

[0135] The wearable device includes an earphone part 100 and an earphone body 200, wherein the earphone body 200 is provided with a first air pressure sensor 210, and an air pressure regulating mechanism 120 and a second air pressure sensor are provided in the earphone part 100;

[0136] The control unit 220 includes:

[0137] The air pressure analysis module 221 is configured to collect and analyze the ambient air pressure value and the air pressure value in the ear canal to determine whether the preset ear pressure adjustment conditions are met;

[0138] The adjustment control module 223 is configured to control the air pressure adjustment mechanism 120 to adjust the air pressure in the ear canal according to the preset ear pressure adjustment level and based on the pressure adjustment rate corresponding to the ear pressure adjustment level when the preset ear pressure adjustment condition is met.

[0139] Furthermore, the system for adaptively adjusting ear pressure also includes:

[0140] The feature matching module 222 is configured to obtain individual feature information of the user and determine an ear pressure adjustment level based on the individual feature information. The obtained ear pressure adjustment level is a preset ear pressure adjustment level.

[0141] It is understandable that the feature matching module 222 can be input by the user through the mobile phone APP, and the APP retrieves the matching gear parameters from the cloud and sends them to the headset for acquisition.

[0142] In an optional embodiment, the adjustment mechanism 120 includes:

[0143] A servo motor, wherein the output shaft of the servo motor is connected to a transmission screw;

[0144] The pneumatic diaphragm piston is connected to the transmission screw through a threaded pair, which converts the rotational motion of the screw into the axial linear motion of the piston;

[0145] An air pressure chamber, wherein the inner wall of the air pressure chamber forms a sealed sliding fit with the air pressure diaphragm piston;

[0146] The forward and reverse rotation of the servo motor drives the air pressure diaphragm piston to move axially, thereby changing the volume of the air pressure chamber.

[0147] like Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of the adaptive ear pressure adjustment system provided in an embodiment of the present application, comprising an in-ear portion 100 and an earphone body 200. The in-ear portion 100 includes an earplug 110 and an adjustment mechanism 120, which comprises a second air pressure sensor, an air pressure chamber, a servo motor, and an air pressure diaphragm piston. The earphone body 200 includes a first air pressure sensor 210 and a control unit 220. The adjustment mechanism 120 and the earphone body 200 are connected via a hot-swappable assembly 300.

[0148] In an optional embodiment, the earplug 110 is made of liquid silicone rubber (LSR) or polyurethane foam and has a hollow design, forming an air chamber. The air chamber is sealed to the earplug 110 via a metal sealing ring to ensure airtightness. A second air pressure sensor is located within the air chamber to monitor the air pressure in the ear canal in real time. The servo motor is connected to the air diaphragm piston via a drive screw. Its forward and reverse rotation drives the piston axially to change the volume of the air chamber, thereby regulating the air pressure in the ear canal.

[0149] The first air pressure sensor 210 of the earphone body 200 is used to detect the ambient air pressure in real time. The control unit 220, integrated into the earphone's main control chip, includes an air pressure analysis module 221, a feature matching module 222, and an adjustment control module 223. The hot-swap assembly 300 is connected to the control unit 220 and physically connects and powers the adjustment mechanism 120 to the earphone body 200 via GPIO pins and an electromagnetic induction coil, thereby supporting the hot-swap functionality of the adjustment mechanism 120.

[0150] It is understandable that when the adjustment mechanism 120 is no longer needed, it can be removed from the earphone body 200 and the ear cap 110 can be installed on the earphone body 200 alone.

[0151] In the system provided by this embodiment, since the earphone inlet 100 and the earphone body 200 are detachably connected, different earphone inlet 100s can be matched to different users during actual use, which is conducive to improving the adaptability of the product to different users. In addition, since the earphone inlet 100 and the earphone body 200 are hot-swappable, the detachment of the earphone inlet 100 does not affect the normal use of the earphone.
