Description

Technical Field

[0001] The present invention relates to earphone wearing detection technology, and in particular to an earphone wearing status detection method, device, electronic equipment and storage medium. Background Art

[0002] In recent years, with the popularity of smart wearable devices such as true wireless stereo (TWS) headphones, users' demand for intelligent interactive experiences has continued to increase. To achieve functions such as automatic playback control, call management, and active noise cancellation switching, headphones need to be able to accurately identify whether the user is wearing them and provide corresponding intelligent responses in different usage scenarios.

[0003] To meet these needs, the industry has proposed a variety of headphone wear detection solutions. Some of these solutions rely on physical sensors, such as infrared proximity sensors, capacitive sensors, or skin contact detection modules, to monitor changes in the distance or contact between the headphone and the ear. These solutions offer advantages such as clear implementation principles and fast response times, but they often rely on additional hardware components, which can increase the complexity of headphone design, increase power consumption, or impose higher requirements on spatial layout, limiting their application in miniaturized headphones.

[0004] Some solutions also attempt to leverage certain system operating parameters or environmental state changes to indirectly infer whether a user is wearing headphones. These technologies typically optimize software algorithms while maintaining fixed hardware resources, offering significant cost advantages. However, in practice, they are susceptible to environmental fluctuations and individual user differences, leading to misjudgments and missed detections. This is especially true in complex scenarios such as low noise levels, weak signals, or improper wear. Detection robustness and accuracy still require improvement.

[0005] While existing headphone wear detection technologies have demonstrated some practicality, they still face technical bottlenecks such as insufficient detection accuracy, poor environmental adaptability, and limited algorithm robustness. Accurately determining wear status in dynamically changing scenarios remains a particular challenge. Therefore, improving the accuracy and stability of wear detection without significantly increasing hardware costs has become a key technical issue that urgently needs to be addressed in this field.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0050] See Figure 1 One embodiment of the present invention provides a method for detecting a wearing state of an earphone, comprising the following steps:

[0051] Step S110: After the earphone is removed from the charging compartment, a first detection signal and a second detection signal of the current state of the earphone are collected.

[0052] This step is used to start the multi-channel acquisition mechanism to acquire data on the external and internal acoustic environments after the earphones are separated from the charging case and enter the ready-to-wear or worn state. The acquisition operation can be triggered by a detection control signal when the earphones are separated from the charging case. For example, it can be automatically started through the disconnection of the charging contacts, the opening signal of the case cover, or the low-power Bluetooth protocol instruction, providing the necessary original acoustic data for the status determination of the subsequent steps.

[0053] Furthermore, the first detection signal is collected by the headset microphone, and the second detection signal is collected by the headset speaker after playing a test sound wave within a specified time window, such as low-frequency / infrasound wave data. In a more specific embodiment, the first detection signal is used to describe the difference in sound pressure inside and outside the ear canal, and the second detection signal represents the energy value of the infrasound wave.

[0054] Specifically, the first detection signal includes collecting a first noise signal and a second noise signal using the headphone's feedforward microphone (FFMIC) and feedback microphone (FBMIC), respectively. The feedforward microphone is typically located on the outside of the headphone, facing the external environment, and is used to capture ambient noise, which is recorded as the first noise signal. The feedback microphone is typically located on the inside of the headphone, facing the ear canal, and is used to capture the actual sound in the ear canal, which is recorded as the second noise signal. This includes the audio played by the headphone and residual noise.

[0055] The second detection signal is a test sound wave played by the speaker of the earphone, such as an infrasound wave, and can usually be received as an ear canal reflection signal by a built-in FBMIC.

[0056] Step S120: Calculate a first detection parameter according to the first detection signal.

[0057] This step processes the first detection signal obtained in step S110 to extract acoustic characteristic parameters reflecting the wearing status. The relevant calculations can be directly completed by the digital signal processor (DSP) on the earphone side directly receiving the signal for processing.

[0058] The sound pressure difference reflects the difference, ratio, or functional relationship between the sound pressure outside the earphone and the sound pressure inside the ear canal. It can be defined and calculated in different ways. When the earphone is not worn, the difference between the inside and outside of the ear canal is small, and the sound pressure difference is typically low (e.g., 0–5dB). When the earphone is worn tightly, the ear canal is closed, and the sound pressure received by the FBMIC is significantly attenuated. The sound pressure difference is typically higher (e.g., 15–30dB). In this case, the sound pressure difference threshold can serve as a basis for judgment.

[0059] Specifically, the signals collected by FFMIC and FBMIC are synchronized to the same time window and preprocessed (such as band-pass filtering and time domain DC drift removal). The effective sound pressure value (RMS) or short-time energy of the feedforward and feedback signals are calculated respectively, and the difference between the feedforward sound pressure and the feedback sound pressure is calculated and recorded as the first detection parameter.

[0060] Step S130: Calculate a second detection parameter according to the second detection signal.

[0061] Specifically, this step analyzes the test sound waves emitted by the speaker to extract an energy indicator representing the degree of coupling. A feedback microphone can then be used to pick up the response signal of the test sound waves within the ear canal. Similarly, the headphone's digital signal processor (DSP) directly receives and processes the signal. When the earphones are worn in the ear canal, the closed acoustic cavity creates an enhanced sound wave reflection, and the collected energy value is significantly higher than when the earphones are not worn.

[0062] Step S140: Compare the first detection parameter with the first preset condition to obtain a first comparison result, and compare the second detection parameter with the second preset condition to obtain a second comparison result.

[0063] This step compares the thresholds of the two detection parameters to obtain conclusions about their respective statuses. Specifically, for the first detection parameter, represented by the sound pressure difference value, a preset in-ear characteristic value can be set. If this value is reached, the first preset condition is satisfied. For the second detection parameter, represented by the sound wave energy value, a preset in-ear threshold value can be set. If this value is reached, the second preset condition is satisfied.

[0064] The essence of the first comparison result and the second comparison result is represented as satisfying the preset condition or not satisfying the preset condition.

[0065] Step S150: Determine the wearing status of the earphone according to the first comparison result and the second comparison result.

[0066] This step forms the final state judgment based on the combination of the two comparison results. Specifically, if both comparison results meet the preset conditions, it is determined that the earphone is currently in the in-ear state, otherwise it is in the out-of-ear state. The state judgment logic proposed by the present invention is that the earphone is only determined to be in-ear when both comparison results meet the preset conditions. If only one comparison result meets the conditions or both comparison results do not meet the conditions, it is not determined that the earphone is in-ear. The sound pressure difference calculation may cause misjudgment in a high-noise environment, and the sound wave energy detection can provide additional verification, thereby improving the robustness of the overall system.

[0067] Furthermore, within the detection cycle, if any comparison result does not meet the preset conditions, the corresponding signal acquisition, parameter calculation and comparison process are repeated until the preset number of times is reached. If before the preset number of times is reached, any comparison result meets the preset conditions, the corresponding comparison result is output as meeting the preset conditions. If the preset conditions are still not met when the preset number of times is reached, the corresponding comparison result is output as not meeting the preset conditions.

[0068] Specifically, step S150 includes the following process:

[0069] When the first comparison result does not meet the preset condition, return to executing the acquisition of the first detection parameter until the first preset number of times is reached;

[0070] and / or,

[0071] When the second comparison result does not meet the preset condition, returning to execute collecting the second detection parameter until a second preset number of times is reached;

[0072] The wearing state of the earphone is determined according to the first comparison result and the second comparison result.

[0073] By setting a first preset number and a second preset number (which can be the same or independently configured), when the first comparison result of any detection parameter does not meet the preset conditions, a multi-cycle repetition mechanism is introduced to make the judgment process more resistant to accidental disturbances, signal jitter or transient unstable states.

[0074] In order to better understand the present invention, the technical solutions of the present invention are described in detail below in conjunction with specific embodiments, but the present invention is not limited to the contents defined in the following embodiments.

[0075] See Figure 2 One embodiment of the present invention provides a method for detecting the wearing status of an earphone, which is applicable to an in-ear wireless earphone system including a feedforward microphone (FFMIC), a feedback microphone (FBMIC), a speaker (SPK), and a digital signal processor (DSP). The method comprises the following steps:

[0076] Step S210: collecting detection signals.

[0077] When it is detected that the earphones have been removed from the charging case (for example, triggered by disconnection from the charging port, power recovery, or lid opening), the DSP controls the microphone module to start working. Within a preset time window (for example, 100ms), it collects: the environmental residual sound signals received by the FFMIC and FBMIC, which are recorded as the first detection signal; and the response signal received by the FBMIC during the playback of the infrasound test waveform (such as an 80Hz sine wave), which is recorded as the second detection signal.

[0078] The test waveform can be emitted by the SPK inside the headset, with a duration of 50ms~200ms and an amplitude that does not affect user perception (below the hearing threshold).

[0079] Step S220: Calculate the first detection parameter.

[0080] The DSP calculates the effective sound pressure (RMS) values ​​of the FFMIC channel and the FBMIC channel in the first detection signal respectively, and further calculates the sound pressure difference value as the first detection parameter.

[0081] Step S230: Calculate the second detection parameter.

[0082] The DSP extracts the response waveform under SPK excitation from the second detection signal, and performs single-point energy calculation on it as the second detection parameter.

[0083] Step S240: Compare the detection parameters with the preset conditions.

[0084] The system sets a preset in-ear characteristic value and a preset in-ear threshold, and the DSP judges respectively: if the first detection parameter reaches the preset in-ear characteristic value, the first comparison result is "meets the preset conditions"; if the second detection parameter reaches the preset in-ear threshold, the second comparison result is "meets the preset conditions".

[0085] When the first comparison result or the first result of the second comparison result is "does not meet the preset conditions", the corresponding signal acquisition, parameter calculation and comparison process are repeated, and the preset number of times is 50 times. If the comparison result is "satisfies the preset conditions" within the 50-time detection cycle, it will stop. If it reaches the preset number of 50 times and is still "does not meet the preset conditions", the final comparison result is output as "does not meet the preset conditions".

[0086] Step S250: Determine the current wearing state of the headset according to the first comparison result and the second comparison result.

[0087] Determine the current wearing status based on two comparison results:

[0088] (1) If both comparison results are "satisfying the preset conditions", it is determined that the earphone is in the in-ear state;

[0089] (2) If any comparison result is "does not meet the preset conditions", it is determined that the earphones are in the out-of-ear state.

[0090] For the application of the present invention, when the in-ear state is detected, the system can automatically turn on the active noise reduction function or resume the paused audio playback; when the out-of-ear state is detected, the system pauses the audio output and turns off the noise reduction to avoid power waste and audio leakage.

[0091] The above-disclosed embodiments describe in detail a method for detecting the wearing status of an earphone, which collects a first detection signal and a second detection signal of the current status of the earphone, which are respectively used to calculate a first detection parameter and a second detection parameter, and compares the two detection parameters with different preset conditions to obtain two comparison results. The wearing status of the earphone is determined by considering the two comparison results at the same time. The present invention introduces two independent detection parameters at the same time, which respectively reflect the acoustic environment and physical coupling state of the earphone, and judges the wearing status through two-dimensional signal fusion, which significantly improves the robustness and misjudgment tolerance of wearing detection, and is particularly suitable for accurate judgment in complex sound fields or atypical wearing scenarios; a further embodiment only relies on the microphone and speaker modules already available in the conventional configuration of the earphone for signal acquisition, and the relevant judgment process can be completed in the digital signal processor (DSP) on the earphone side, with high integration and low power consumption, and is easy to be quickly deployed and implemented in the existing earphone system.
