Description

[Technical Field]

[0001] This application claims priority to a Chinese patent application bearing application number 202111258842.3, filed with the China Patent Office on October 28, 2021, the entire contents of which are incorporated herein by reference.

[0002] The embodiments of the present application relate to the technical field of data processing, for example, to a control method and device for earphones, earphones, and storage media. [Background technology]

[0003] In recent years, true wireless stereo (TWS) earphones have been widely used. When not in use or after use, TWS earphones are generally placed in an earphone charging case to replenish the power of the TWS earphones. During the process of using the earphones, the TWS earphones usually detect the state of ear insertion and the pressure sensory inputs made by the user to the earphones.

[0004] TWS earphones typically detect the earbud insertion state and pressure input according to the user's touch on the earphone. Because a user's touch on the earphone causes a change in the earphone's parasitic capacitance, TWS earphones can detect touch operations by detecting the change in capacitance. When a user touches the earphone, the capacitance increases and the capacitor charging speed slows, resulting in a smaller capacitor voltage value within the same charging time. Conversely, when a user releases the earphone, the capacitance decreases and the capacitor charging speed increases, resulting in a larger capacitor voltage value within the same charging time. TWS earphones in the related art use an analog-to-digital converter (ADC) to sample the capacitor voltage value and determine whether the user has touched or released the earphone by detecting the voltage value.

[0005] However, in the related art, TWS earphones have low detection sensitivity for touch operations, making them prone to false detection due to environmental changes such as temperature and humidity, as well as accidental touches. In addition, TWS earphones in the related art require two different touch detection paths to respectively detect the earbud placement and pressure input, resulting in large hardware overhead. Summary of the Invention [Problem to be solved by the invention]

[0012] The present application will be described below with reference to the drawings and examples. It will be understood that the specific examples described here are merely for the purpose of interpreting the present application and are not intended to limit the present application. For the sake of convenience, the drawings show only parts relevant to the present invention, rather than all of the structures.

[0013] Example 1 FIG. 1a is a flowchart of a method for controlling an earphone according to a first embodiment of the present application. This embodiment is applicable to controlling the operation of an earphone. The method can be executed by a control device of the earphone, which can be implemented in software and / or hardware and can generally be integrated into a wireless earphone. The method for controlling the earphone includes the following steps:

[0014] In step 110, a first voltage sequence corresponding to a first capacitor and a second voltage sequence corresponding to a second capacitor in the target earphone are sequentially sampled based on a preset sampling period, and the first capacitor and the second capacitor are respectively located at different positions in the target earphone.

[0015] In this step, the first capacitor may be a capacitor located inside the target earphone, and the second capacitor may be a capacitor located outside the target earphone. A first voltage sequence corresponding to the first capacitor and a second voltage sequence corresponding to the second capacitor may be sequentially sampled according to a preset sampling period using a time division multiplexing method. Each of the first voltage sequence and the second voltage sequence may include a plurality of voltage values.

[0016] 1b is a time sequence diagram of a voltage sequence acquisition process according to Example 1 of the present application, and as shown in FIG. 1b, a plurality of first voltage sequences and a plurality of second voltage sequences can be acquired based on a preset sampling period. In one sampling period, channel 1 can be used to acquire a first voltage sequence that may include a plurality of voltage values ​​corresponding to a first capacitor, and channel 2 can be used to acquire a second voltage sequence that may include a plurality of voltage values ​​corresponding to a second capacitor.

[0017] In step 120, a first working state of the target earphone is determined based on the first voltage sequence and a preset first reference voltage, and an in-ear state of the target earphone is determined based on the first working state.

[0018] In this step, the first reference voltage may be a preset voltage value corresponding to the first capacitor, and is used to detect the in-ear state of the target earphone. Preferably, the voltage values ​​in a plurality of consecutive first voltage sequences are compared with the preset first reference voltage, and the first working state of the target earphone is determined according to the comparison result.

[0019] In one embodiment, a plurality of voltage values ​​included in each first voltage sequence are averaged to obtain a plurality of average values ​​corresponding to the plurality of first voltage sequences, and a difference value between each of the first reference voltages and each average value is calculated. It is then determined whether N consecutive difference values ​​are all greater than a preset touch threshold. If the N consecutive difference values ​​are all greater than the preset touch threshold, it is determined that the first operating state of the target earphone is a touch state; if the N consecutive difference values ​​are less than or equal to the preset touch threshold, it is determined that the first operating state of the target earphone is a untouched state. N may be a preset value greater than 1.

[0020] In this step, if the first operating state of the target earphone is a touch state, it can be determined that the in-ear state of the target earphone is a wearing state; if the first operating state of the target earphone is a non-touch state, it can be determined that the in-ear state of the target earphone is a non-wearing state.

[0021] In step 130, a second operating state of the target earphone is determined based on the second voltage sequence and a preset second reference voltage, and a pressure sense input operation performed by a user on the target earphone is determined based on the second operating state.

[0022] In this step, the second reference voltage may be a preset voltage value corresponding to a second capacitor, and is used to detect whether a user performs a pressure-sense input operation on the target earphone. Preferably, the voltage values ​​in a plurality of consecutive second voltage sequences can be compared with a preset second reference voltage, and the second working state of the target earphone can be determined according to the comparison result.

[0023] In one embodiment, a plurality of voltage values ​​included in each second voltage sequence are averaged to obtain a plurality of average values ​​corresponding to the plurality of second voltage sequences, and a difference value between each average value and the second reference voltage is calculated. It is then determined whether N consecutive difference values ​​are all greater than a preset touch threshold. If the N consecutive difference values ​​are all greater than the preset touch threshold, it is determined that the second operating state of the target earphone is a touch state; if the N consecutive difference values ​​are less than the preset touch threshold, it is determined that the second operating state of the target earphone is a untouched state. N may be a preset value greater than 1.

[0024] In this step, if the second operating state of the target earphone is a touch state, it can be determined that the user has performed a pressure-sense input operation on the target earphone; if the first operating state of the target earphone is a non-touch state, it can be determined that the user has not performed a pressure-sense input operation on the target earphone.

[0025] In step 140, the target earphone is controlled according to the ear insertion state and the determination result of the pressure-sense input operation, so as to execute an operation command that matches the determination result.

[0026] In one embodiment, if the in-ear state of the target earphone is a worn state, the execution of an on command of the target earphone can be controlled so that the target earphone starts playing audio specified by a user; if the in-ear state of the target earphone is a dismounted state and the target earphone is playing audio, the execution of a pause command of the target earphone can be controlled so that the target earphone stops playing the current audio.

[0027] In another embodiment, if it is detected that a user has performed a pressure input operation on the target earphone, the target earphone can be controlled to perform an operation command that matches the pressure input operation, such as a pause command, an off command, or a command to play the next audio.

[0028] In this embodiment, by sequentially collecting the first voltage sequence corresponding to the first capacitor and the second voltage sequence corresponding to the second capacitor using a time division multiplexing method, it is possible to detect the earphone insertion state and the pressure input using only one detection path, thereby reducing the hardware overhead in the detection process and saving detection costs. Meanwhile, by periodically obtaining a plurality of first voltage sequences and a plurality of second voltage sequences, determining the earphone insertion state of the target earphone based on the plurality of first voltage sequences and the first reference voltage, and determining the pressure input operation performed by the user on the target earphone based on the plurality of second voltage sequences and the second reference voltage, it is possible to improve the detection sensitivity of the earphone and the accuracy of the detection results.

[0029] A technical aspect of an embodiment of the present application is to sequentially collect a first voltage sequence corresponding to a first capacitor in the target earphone and a second voltage sequence corresponding to a second capacitor in the target earphone based on a preset sampling period, determine a first operating state of the target earphone based on the first voltage sequence and a first reference voltage, determine the in-ear state of the target earphone based on the first operating state, determine a second operating state of the target earphone based on the second voltage sequence and a second reference voltage, determine a pressure-sense input operation performed by the user on the target earphone based on the second operating state, and control the target earphone to execute a corresponding operation command according to the determined in-ear state and pressure-sense input operation. Through these technical measures, it is possible to improve the earphone's detection sensitivity for the in-ear state and the pressure-sense input and reduce the hardware overhead in the earphone detection process.

[0030] Example 2 This embodiment is a subdivision of the above-mentioned embodiment 1, and the interpretation of the same or corresponding terms as those in the above-mentioned embodiment will not be repeated in this embodiment. Figure 2 is a flowchart of an earphone control method according to embodiment 2 of the present application, and in this embodiment, the technical aspects of this embodiment can be combined with one or more methods in the aspects of the above-mentioned embodiment. In this embodiment, as shown in Figure 2, the method according to the embodiment of the present application may further include:

[0031] In step 210, a first voltage sequence corresponding to a first capacitor and a second voltage sequence corresponding to a second capacitor in the target earphone are sequentially sampled based on a preset sampling period, where the first capacitor and the second capacitor are respectively located at different positions in the target earphone.

[0032] In step 220, a smoothing filtering process is performed on the plurality of first voltage sequences to obtain voltage filtering results.

[0033] In this embodiment, in order to improve the accuracy of the earphone detection results for the ear placement state and pressure input, a smoothing filtering process can be performed on the multiple first voltage sequences, and the voltage filtering result can be obtained by averaging the multiple voltage values ​​in the multiple first voltage sequences.

[0034] In this embodiment, preferably, performing a smoothing filtering process on a plurality of first voltage sequences to obtain a voltage filtering result includes removing a maximum voltage value and a minimum voltage value in each first voltage sequence, taking an average value for the remaining plurality of voltage values ​​in each first voltage sequence to obtain a plurality of voltage average values ​​(each voltage average value corresponds to one first voltage sequence), and then taking an average value for the plurality of voltage average values ​​to obtain the voltage filtering result.

[0035] In one embodiment of the present application, after performing a smoothing filtering process on the plurality of first voltage sequences and obtaining a voltage filtering result, the method further includes determining a current calibration parameter corresponding to the first capacitor based on the voltage filtering result and the first reference voltage, and calibrating a current current value corresponding to the first capacitor based on the current calibration parameter.

[0036] In this embodiment, in order to prevent the earphone from making an erroneous detection due to environmental changes such as temperature and humidity, or due to an erroneous touch, this embodiment proposes an embodiment for calibrating the current value corresponding to the first capacitor and the current value corresponding to the second capacitor, where the calibration methods corresponding to the first capacitor and the second capacitor are the same, and this embodiment only takes the first capacitor as an example to describe the process of calibrating the current value of the first capacitor.

[0037] In this embodiment, determining a current calibration parameter corresponding to the first capacitor based on the voltage filtering result and the first reference voltage, and calibrating a current value corresponding to the first capacitor based on the current calibration parameter includes:

[0038] In step 200, a current calibration parameter corresponding to the first capacitor is determined based on the voltage filtering result and the first reference voltage.

[0040] In step 201, a current value corresponding to the first capacitor is calibrated according to the current calibration parameters and preset capacitance digital conversion parameters.

[0041] In this step, preferably, a preset linear conversion algorithm can be used to calibrate the current value corresponding to the first capacitor based on the current calibration parameters and preset capacitance digital conversion parameters (CDC).

[0042] In step 202, the current voltage filtering result obtained after the first capacitor current calibration is obtained, and a voltage difference value between the first reference voltage and the current voltage filtering result is calculated.

[0043] In this step, by performing the above steps 210 to 220, the current voltage filtering result obtained after the calibration of the current of the first capacitor is obtained, and the first reference voltage

[0044] In step 203, it is determined whether the absolute value of the voltage difference value is equal to or greater than a preset threshold value. If the absolute value of the voltage difference value is equal to or greater than the preset threshold value, step 204 is executed; if the absolute value of the voltage difference value is smaller than the preset threshold value, step 205 is executed.

[0045] In step 204, it is determined whether the current number of calibrations is equal to or less than the maximum number of calibrations. If the current number of calibrations is equal to or less than the maximum number of calibrations, step 206 is executed; if the current number of calibrations is greater than the maximum number of calibrations, step 207 is executed.

[0046] In this embodiment, the current number of calibrations can be counted every time a calibration process for the current current value corresponding to the first capacitor is completed.

[0047] In step 205, the calibration process for the current current value corresponding to the first capacitor is stopped.

[0048] In step 206, adjust the capacitance-digital conversion parameters until the absolute value of the voltage difference value is smaller than a preset threshold value or the current calibration number is greater than the maximum calibration number, and return to performing the operation of determining the current calibration parameters corresponding to the first capacitor based on the voltage filtering result and the first reference voltage in step 200.

[0050] In this step, after adjusting the CDC, the process returns to step 200, and if the absolute value of the voltage difference value is smaller than the preset threshold value or the current calibration count is greater than the maximum calibration count, the calibration process for the current current value corresponding to the first capacitor is stopped.

[0051] In step 207, it is determined whether the current voltage filtering result is within a preset interval. If the current voltage filtering result is within the preset interval, step 208 is executed; if the current voltage filtering result is not within the preset interval, step 209 is executed.

[0052] In this embodiment, if the current calibration count is greater than the maximum calibration count, the current voltage filtering result is

[0053] Step 208 confirms that the calibration process is complete.

[0054] In step 209, a preset calibration incorrect flag is output, and the current current value corresponding to the first capacitor is calibrated using the initialized capacitance digital conversion parameters and the preset current calibration parameters.

[0056] By calibrating the current value corresponding to the first capacitor and the current value corresponding to the second capacitor, it is possible to prevent the earphone from making false detections due to environmental changes such as temperature and humidity, or due to accidental touches, and it is also possible to improve the earphone's detection sensitivity to the ear insertion state and pressure input.

[0057] In step 230, a first working state of the target earphone is determined based on the voltage filtering result and the first reference voltage.

[0058] In step 240, an in-ear state of the target earphone is determined based on the first operating state.

[0059] In step 250, a second operating state of the target earphone is determined based on the second voltage sequence and a preset second reference voltage, and a pressure sense input operation performed by a user on the target earphone is determined based on the second operating state.

[0060] In this step, the same method as in steps 220 to 230 is adopted to perform a smoothing filtering process on the plurality of second voltage sequences to obtain a voltage filtering result, and then a second working state of the target earphone can be determined according to the voltage filtering result and the second reference voltage.

[0061] In step 260, the target earphone is controlled according to the ear insertion state and the determination result of the pressure-sense input operation, so as to execute an operation command that matches the determination result.

[0062] A technical aspect of an embodiment of the present application is to sequentially collect a first voltage sequence corresponding to a first capacitor and a second voltage sequence corresponding to a second capacitor in the target earphone based on a preset sampling period, perform a smoothing filtering process on the multiple first voltage sequences to obtain a voltage filtering result, determine a first operating state of the target earphone based on the voltage filtering result and a first reference voltage, determine the in-ear state of the target earphone based on the first operating state, determine a second operating state of the target earphone based on the second voltage sequence and the second reference voltage, determine a pressure-sense input operation performed by the user on the target earphone based on the second operating state, and control the target earphone to execute a corresponding operation command according to the determined in-ear state and pressure-sense input operation. Through these technical means, it is possible to improve the earphone's detection sensitivity for the in-ear state and the pressure-sense input and reduce the hardware overhead in the earphone detection process.

[0063] Example 3 This embodiment is a subdivision of the above-mentioned embodiment 1, and the interpretation of the same or corresponding terms as those in the above-mentioned embodiment will not be repeated in this embodiment. Figure 3a is a flowchart of a method for controlling earphones according to embodiment 3 of the present application, and in this embodiment, the technical aspects of this embodiment can be combined with one or more methods in the aspects of the above-mentioned embodiment. In this embodiment, as shown in Figure 3a, the method according to the embodiment of the present application may further include:

[0064] In step 301, a first voltage sequence corresponding to a first capacitor and a second voltage sequence corresponding to a second capacitor in a target earphone are sequentially sampled based on a preset sampling period, and the first capacitor and the second capacitor are respectively located at different positions in the target earphone.

[0065] In step 302, a smoothing filtering process is performed on the plurality of first voltage sequences to obtain voltage filtering results.

[0066] In step 303, it is determined whether the voltage difference value between the first reference voltage and the voltage filtering result is greater than a preset touch threshold. If the voltage difference value between the first reference voltage and the voltage filtering result is greater than the preset touch threshold, step 304 is executed; if the voltage difference value between the first reference voltage and the voltage filtering result is equal to or less than the preset touch threshold, step 305 is executed.

[0067] In step 304, it is determined that a touch event occurs on the target earphone.

[0068] In step 305, it is determined that no touch event has occurred on the target earphone.

[0069] In step 306, it is determined whether the duration of the touch event is greater than a preset time threshold. If the duration of the touch event is greater than the preset time threshold, step 307 is executed; if the duration of the touch event is equal to or less than the preset time threshold, step 308 is executed.

[0070] In step 307, determine that the first working state of the target earphone is a non-touch state.

[0071] In this embodiment, if the duration of the touch event is greater than a preset time threshold, it can be determined that an erroneous touch may have occurred on the target earphone, and the first operating state of the target earphone can be determined to be a untouched state to avoid any fraudulent detection results.

[0072] In step 308, the number of times that a touch event occurs in the target earphone within the set time period is counted, and the process returns to step 301, where the process sequentially collects a first voltage sequence corresponding to the first capacitor and a second voltage sequence corresponding to the second capacitor in the target earphone according to the preset sampling period.

[0073] In this embodiment, each time it is detected that a touch event has occurred on the target earphone, the number of times that a touch event has occurred on the target earphone within a set time period is counted.

[0074] In step 309, it is determined whether the number of consecutive touch events occurring in the target earphone within the set time period is equal to a first threshold value. If the number of consecutive touch events occurring in the set time period is equal to the first threshold value, step 310 is executed; if the number of consecutive touch events occurring in the set time period is not equal to the first threshold value, step 311 is executed.

[0075] In step 310, determine that the first operating state of the target earphone is a touch state.

[0076] In step 311, determine whether the number of times that no touch events have occurred consecutively in the target earphone within the set time period is equal to a second threshold. If the number of times that no touch events have occurred consecutively in the target earphone within the set time period is equal to the second threshold, execute step 312; if the number of times that no touch events have occurred consecutively in the target earphone within the set time period is not equal to the second threshold, return to executing the operation of step 301, which sequentially collects a first voltage sequence corresponding to a first capacitor and a second voltage sequence corresponding to a second capacitor in the target earphone based on a preset sampling period.

[0077] In step 312, determine that the first operating state of the target earphone is a untouched state.

[0078] In step 313, an in-ear state of the target earphone is determined based on the first operating state.

[0079] In step 314, a second operating state of the target earphone is determined based on the second voltage sequence and a preset second reference voltage, and a pressure sense input operation performed by a user on the target earphone is determined based on the second operating state.

[0080] In this embodiment, the method for determining the second working state of the target earphone is the same as the method for determining the first working state, and this embodiment will not repeat the description thereof.

[0081] In step 315, the target earphone is controlled according to the ear insertion state and the determination result of the pressure-sense input operation, so as to execute an operation command that matches the determination result.

[0082] In one embodiment of the present invention, the method further includes updating the first reference voltage based on a voltage difference between the voltage filtering result and the first reference voltage, and updating the second reference voltage based on a voltage difference between the voltage filtering result corresponding to the second voltage sequence and the second reference voltage, where the updating manner of the first reference voltage is the same as that of the second reference voltage, and this embodiment only takes the first reference voltage as an example to describe the updating manner.
