[0056] figure 1 is a structural schematic diagram of the earphone to which this embodiment is applied. refer to figure 1 , this embodiment provides an earphone 10 , the earphone 10 includes a capacitive component 101 , a speaker 102 and a microphone 103 .
[0057] The capacitive part 101 can form a capacitor. The capacitive component 101 may specifically be a metal sheet of the earphone 10, such as a metal sheet disposed on the top of the earphone or inside the earmuff. When the earphone 10 is worn, the capacitance value of the capacitive component 101 will change; wherein, the capacitance value is the capacitance value between the capacitive component 101 and the human body.
[0058] The horn 102 is used to convert electrical signals into sound. Horn 102 may also be referred to as a speaker.
[0059] The microphone 103 is used to convert the sound signal into an electrical signal, so as to receive sound. Specifically, the microphone 103 may be an inner microphone dispos...

[0081] Figure 4 It is a schematic flowchart of step A1 of the method for detecting the wearing state of the earphone provided in this embodiment. refer to Figure 4 , in this embodiment, step A1 (determine the first wearing state of the earphone according to the received sound) further includes step A11, step A12, step B14 and step B13.
[0082] The specific content of step A11 and step A12 is the same as that of the first embodiment.
[0083] Step B14, performing correlation analysis on the first data and the second data to obtain the correlation.
[0084] As mentioned above, the first data is the audio data played by the speaker 102 , and the second data is the second data obtained by the microphone 103 recording the sound played by the speaker 102 . The correlation can be obtained by performing a correlation analysis on the first data and the second data. Among them, the aforementioned correlation analysis is to analyze the similarity between the first data and the sec...

[0089] Figure 5 It is a schematic flowchart of the method for detecting the wearing state of the earphone provided in this embodiment. refer to Figure 5 , the method provided in this embodiment further includes step A4.
[0090] Step A4. Determine a third wearing state of the earphone according to the first wearing state and the second wearing state.
[0091] After the earphone is turned on, in the process of playing music, use the microphone 103 to record the audio data (also called the first data) played by the speaker 102 at the same time to obtain the second data; The first transfer function from the loudspeaker 102 to the microphone 103; the first transfer function is compared with the preset transfer function (that is, the first preset transfer function) to obtain a contrast, wherein the contrast represents the consistency of the aforementioned two transfer functions property; as mentioned above, determine the first wearing state of the earphone according to the con...
