Referring to fig. 1 in detail, fig. 1 is a schematic flow chart of an embodiment of an identification method of an earphone according to the present application. The method for recognizing the earphone of the embodiment includes the following steps.
S101: and after detecting the access of the earphone, sequentially sending a plurality of detection signals with different frequencies to the earphone.
The mobile terminal and the earphone can be connected in a wireless mode or a wired mode.
The mobile terminal is provided with an earphone detection pin. When the mobile terminal is connected with the earphone in a wired mode, the earphone detection pin can be used for detecting whether the earphone is inserted into the mobile terminal, so that a feasible mode for detecting whether the earphone is inserted into the mobile terminal is as follows: whether an earphone is inserted is determined by detecting a level of an earphone detection pin of the mobile terminal. The method specifically comprises the following steps: when the level of an earphone detection pin of the mobile terminal is detected to be low, judging that an earphone is inserted into the mobile terminal; and when the level of the earphone detection pin of the mobile terminal is detected to be high, judging that the earphone is not inserted into the mobile terminal.
After detecting the access of the earphone, the mobile terminal may sequentially transmit a plurality of detection signals of different frequencies to the earphone. The frequency of the detection signals which are sequentially sent to the earphones by the mobile terminal can be gradually increased, gradually decreased or not have any rule. The amplitudes of the detection signals of the plurality of different frequencies, which are sequentially sent to the earphone by the mobile terminal, can be the same or different.
S102: and receiving a feedback signal of the earphone after receiving each detection signal so as to confirm whether the frequency of the detection signal is shielded by the earphone.
After receiving the detection signal sent by the mobile terminal, the earphone feeds back a signal to the mobile terminal. Accordingly, the mobile terminal may receive a feedback signal from the headset after receiving each detection signal. According to the received feedback signal, the mobile terminal can confirm whether the frequency of the detection signal sent by the mobile terminal is shielded by the earphone.
S103: and identifying the circuit parameters of the earphone according to the confirmation result of whether the frequency of the detection signal is shielded by the earphone.
The mobile terminal sends all the detection signals required to be sent to the earphone, and after judging whether the frequency of the detection signals is shielded by the earphone, circuit parameters of the earphone can be identified according to the judgment result whether the frequency of the detection signals is shielded by the earphone.
In the embodiment, the mobile terminal sends a plurality of detection signals with different frequencies to the earphone, the mobile terminal receives a feedback signal of the earphone after receiving each detection signal, judges whether the frequency of the detection signal is shielded by the earphone or not through the feedback signal, and determines the circuit parameters of the earphone according to the confirmation result of whether the detection signal with the plurality of different frequencies is shielded by the earphone or not.
Based on the embodiment shown in fig. 1, the present application further proposes a more specific solution, please refer to fig. 2, and fig. 2 is a schematic flow chart of another embodiment of the identification method of the earphone according to the present application. The method for recognizing the earphone of the embodiment includes the following steps.
S201: and after detecting the access of the earphone, sequentially sending a plurality of detection signals with different frequencies to the earphone.
As mentioned above in S101, the detailed description is omitted here.
S202: and receiving a feedback signal of the earphone after receiving each detection signal so as to confirm whether the frequency of the detection signal is shielded by the earphone.
The mobile terminal can judge whether the frequency of the detection signal is shielded by the earphone or not by detecting the amplitude of the feedback signal after the earphone receives each detection signal.
In one application scenario, after the mobile terminal detects the amplitude of the feedback signal, the ratio between the amplitude of the feedback signal and the amplitude of the detection signal may be continuously calculated. And judging whether the ratio of the amplitude of the feedback signal to the amplitude of the detection signal is smaller than a proportional threshold value. If the frequency of the detection signal is smaller than the proportion threshold value, the fact that the frequency of the detection signal is shielded by the earphone can be determined; if the frequency of the detection signal is not smaller than the proportion threshold value, the frequency of the detection signal is determined not to be shielded by the earphone. The proportional threshold may be a preset value, such as 0.6, 0.7, 0.8, 0.9. The amplitudes of the detection signals of the plurality of different frequencies, which are sequentially sent to the earphone by the mobile terminal, can be the same or different. When the amplitudes of the detection signals of the multiple different frequencies sent to the earphone by the mobile terminal are different in sequence, the amplitude of each frequency detection signal sent by the mobile terminal needs to be recorded, so that the ratio of the amplitude of the feedback signal to the amplitude of the detection signal can be conveniently calculated.
In another application scenario, after the mobile terminal detects the amplitude of the feedback signal, it can directly determine whether the amplitude of the feedback signal is smaller than an amplitude threshold. If the amplitude is smaller than the amplitude threshold value, the frequency of the detection signal is determined to be shielded by the earphone; and if the amplitude is not less than the amplitude threshold value, determining that the frequency of the detection signal is not shielded by the earphone. Of course, the amplitudes of the detection signals with different frequencies sequentially sent to the earphone by the mobile terminal can be the same, so that whether the frequency of the detection signal is shielded by the earphone can be directly judged according to the amplitude of the feedback signal, the calculation amount is reduced, and the calculation time is saved.
S203: and confirming the frequency range shielded by the earphone according to the confirmation result of whether the frequency of the detection signal is shielded by the earphone.
The mobile terminal counts whether the detection signals with different frequencies are shielded by the earphone or not, and confirms the frequency range shielded by the earphone.

And if the frequency range is the frequency of all the detection signals, identifying that the circuit type of the earphone is a full-resistance circuit. And if the frequency range is zero, identifying that the circuit type of the earphone is an all-pass circuit.
If the frequency range is the frequency of part of the detection signals, the circuit type of the earphone is identified to be a high-pass circuit, a low-pass circuit, a band-pass circuit or a band-stop circuit, and the cut-off frequency is the frequency value at the end point of the frequency range.
If the frequency is masked when the frequency is greater than the first threshold value and is not masked when the frequency is less than the first threshold value, the type of the earphone circuit is a low-pass circuit, and the cut-off frequency of the low-pass circuit is a frequency value at the end point of the frequency range, namely the first threshold value.
If the frequency is shielded when the frequency is smaller than the second threshold value, and the frequency is not shielded when the frequency is larger than the second threshold value, the type of the earphone circuit is a high-pass circuit, and the cut-off frequency of the high-pass circuit is the second threshold value.
If all frequencies between the third threshold and the fourth threshold are masked by the headset. And is unmasked when the frequency is greater than a fourth threshold and is unmasked when the frequency is less than a third threshold. Wherein the third threshold is less than the fourth threshold. The type of the headphone circuit is a band-stop circuit, and the lower cut-off frequency of the band-stop circuit is a third threshold value and the upper cut-off frequency is a fourth threshold value.
If all frequencies between the fifth threshold and the sixth threshold are not masked by the headset. And masked when the frequency is greater than a sixth threshold and masked when the frequency is less than a fifth threshold. Wherein the fifth threshold is less than the sixth threshold. The type of the headphone circuit is a band pass circuit, and the lower cut-off frequency of the band pass circuit is a fifth threshold value and the upper cut-off frequency is a sixth threshold value.
S205: it is determined whether circuit parameters of the headset are allowed.
The mobile terminal can store corresponding preset circuit parameters, and when the circuit parameters of the earphone can be successfully matched with any preset circuit parameter, the circuit parameters of the earphone can be judged to be allowed; when the circuit parameters of the earphone are not successfully matched with all the preset circuit parameters, the circuit parameters of the earphone can be judged to be not allowed. If yes, go to step S206; if not, the process proceeds to step S207.
S206: a headset is used.
If allowed, the headset can be used. The mobile terminal can start the function of the earphone, so that the earphone can be used by the mobile terminal.
S207: no headphones are used.
If not allowed, the headset cannot be used. The mobile terminal may turn off the function of the headset, making the headset unusable by the mobile terminal.
In the embodiment, the mobile terminal sends a plurality of detection signals with different frequencies to the earphone, the mobile terminal receives a feedback signal of the earphone after receiving each detection signal, judges whether the frequency of the detection signal is shielded by the earphone or not through the feedback signal, and determines the circuit parameters of the earphone according to the confirmation result of whether the detection signal with the plurality of different frequencies is shielded by the earphone or not.
