[0055] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

[0060] Figure 4 This is a block diagram illustrating a step counting device according to an exemplary embodiment. Detailed Implementation

[0061] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0062] It should be noted that all actions involving the acquisition of signals, information, or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where the application is located, and with the authorization granted by the owner of the relevant device.

[0063] Figure 1 This is a flowchart illustrating a step counting method according to an exemplary embodiment, such as... Figure 1 As shown, the step counting method used in the headphones includes the following steps.

[0064] In step S101, the first audio signal and the second audio signal are acquired.

[0065] The first audio signal is the sound signal inside the ear canal of the user wearing the headphones, and the second audio signal is the sound signal in the environment where the user wearing the headphones is located.

[0066] The headphones involved in this disclosure are headphones that include a feedforward microphone and a feedback microphone, such as true wireless stereo (TWS) Bluetooth headphones. The first audio signal can be acquired, for example, through the feedback microphone in the headphones, and the second audio signal can be acquired, for example, through the feedforward microphone in the headphones.

[0067] In one embodiment, the earphones of this disclosure can automatically count steps after the user wears them, or they can count steps after the user turns on the earphones' step counting function.

[0068] In step S102, energy detection is performed on the first audio signal and the second audio signal.

[0069] In addition, in order to remove interference from sounds such as talking and music in the headphones, before performing energy detection on the first audio signal and the second audio signal, the step counting method also includes: filtering out audio signals in the first audio signal and the second audio signal that are above the preset frequency threshold according to a preset frequency threshold.

[0070] The frequency threshold can be 40Hz, 70Hz, etc., and preferably 50Hz, to remove interference from sounds such as talking and music in the headphones.

[0071] In step S103, if the first audio signal is detected to have a maximum energy value within a preset time threshold, the maximum energy value is determined as the current maximum energy value, and the time point corresponding to the current maximum energy value is taken as the target time point.

[0072] When a user wears TWS earphones while running or walking, the sound of their feet hitting the ground is transmitted through the earphone's bone conduction to the ear canal. Consequently, the sound signal in the user's ear canal (the sound of their feet hitting the ground), i.e., the first audio signal, is blocked in the ear by the earphones and amplified, creating an occlusion effect. This results in a maximum energy value within a preset time threshold.

[0073] The preset time threshold can be 80 milliseconds or 120 milliseconds. Preferably, the preset time threshold can be 100 milliseconds.

[0074] In step S104, the target energy value is obtained according to the target time point, wherein the target energy value is the energy value of the audio point in the second audio signal corresponding to the target time point.

[0075] In step S105, the difference between the current maximum energy value and the target energy value is determined. If both of the following conditions are met, a step counting event is determined to have occurred: Condition 1: The difference value is greater than the preset difference threshold; Condition 2: The current maximum energy value is the first maximum energy value detected for the first audio signal.

[0076] In one implementation, the difference between the current energy maximum and the target energy value can be determined, for example, by the following formula: Where C is the maximum energy value at the target time point, D is the target energy value at the target time point, and delta is the difference between the maximum energy value and the target energy value.

[0077] The difference threshold can be 15 dB.

[0078] Furthermore, since the collision signals from a user running or walking are periodic, a step counting event can be determined when the user runs or walks continuously, provided that the following three conditions are met:

[0079] Condition 1: The difference value is greater than a preset difference threshold; Condition 2: The current maximum energy value is not the first maximum energy value detected for the first audio signal; Condition 3: The time difference between the time point corresponding to the current maximum energy value and the time point corresponding to the previously stored maximum energy value meets a preset time difference range, indicating that the user is in a continuous walking or running state. This process is repeated to determine each subsequent step counting event, so that the user does not need to carry other smart devices and can count steps in real time through headphones, improving the user's walking or running comfort.

[0080] The time difference between the current energy maximum and the time of the previously stored energy maximum can be, for example, within 200 milliseconds.

[0081] Figure 2 An example diagram is shown of the real-time energy of the first and second audio signals when the user is walking or running continuously.

[0082] The upper part is the real-time energy map of the first audio signal, and the lower part is the real-time energy map of the second audio signal.

[0083] When a user wears TWS earbuds while running or walking, the sound of their feet hitting the ground is conducted through the earbuds to the ear canal via bone conduction. Consequently, the sound signal (the sound of feet hitting the ground), i.e., the first audio signal, is blocked and amplified by the earbuds, creating an occlusion effect. This results in an instantaneous energy maxima and minimum within a preset time threshold (e.g., 100 milliseconds). Thus, each impact of the foot with the ground will have an instantaneous energy maxima and minimum within the preset time threshold (e.g., 100 milliseconds), forming a real-time energy map of the first audio signal in the time domain.

[0084] Since the second audio signal is the sound signal from the environment in which the user wearing the headphones is located, and the impact sound is almost completely attenuated by the time it reaches the headphones through the air, it can be ignored. Figure 2 The real-time energy of the second audio signal in the time domain is always negative infinity.

[0085] Furthermore, when it is determined that the first audio signal is a false detection caused by occlusion effect rather than sound leakage outside the ear, the energy value of the audio point in the second audio signal corresponding to the target time point where the current energy maximum occurs can be obtained, i.e., the target energy value. Then, the difference between the current energy maximum and the target energy value can be determined. Determine the difference value.

[0086] In an exemplary embodiment of this disclosure, a first audio signal from the ear canal of a user wearing the headphones is acquired, and a second audio signal from the environment in which the user is located is acquired. Energy detection is performed on the first and second audio signals. If a maximum energy value is detected in the first audio signal within a preset time threshold, this maximum energy value is determined as the current maximum energy value, and the time point corresponding to this maximum energy value is designated as the target time point. Based on the target time point, the energy value (i.e., the target energy value) of the audio point in the second audio signal corresponding to the target time point is acquired. Then, the difference between the current maximum energy value and the target energy value is determined. If the difference is greater than a preset difference threshold, it indicates that the first audio signal is caused by a blockage effect, and this current maximum energy value is the first detected maximum energy value for the first audio signal. This indicates that the user has started walking or running while wearing the headphones, and a step counting event is determined to have occurred. Therefore, the user can count steps in real time through the headphones without carrying other smart devices, improving the comfort of walking or running.
