As shown in FIG. 1 , the second connection interface 120 is coupled to the processor 130 . According to an embodiment of the present invention, the second connection interface 120 and the fourth connection interface 220 are general-purpose input and output (General Purpose I/O, GPIO), for example: a Universal Serial Bus (Universal Serial Bus, USB) interface . When the electronic device 100 is to be tested, the second connection interface 120 is coupled to the fourth connection interface 220 to transmit the control signal S1 generated by the processor 130 to the detection device 200 through the fourth connection interface 220 . 4A-4B are schematic diagrams showing generation of the control signal S1 according to an embodiment of the present invention.

When the fourth connection interface 220 receives the control signal S1 , it will transmit the control signal S1 to the switching circuit 230 . The switch circuit 230 determines whether the DC cancellation circuit 250 is to be coupled to the third connection interface 210 or the signal generator 240 according to the control signal S1 . There will be a more detailed description below.

As shown in FIG. 1 , the storage device 140 is coupled to the processor 130 .

As mentioned above, according to the embodiment of the present invention, when the electronic device 100 is to be detected, the first connection interface 110 of the electronic device 100 can be coupled to the third connection interface 210 of the detection device 200 through an earphone connector 300, and the electronic device The second connection interface 120 of 100 is coupled to the fourth connection interface 220 of the detection device 200 . Next, the processor 130 activates a recording device (or a recording module, not shown in the figure), and transmits a control signal to the detection device 200 through the second connection interface 120 . According to an embodiment of the present invention, the recording device is coupled to the processor 130 , which may be an independent circuit or integrated in the processor 130 . The recording device records a microphone signal and a plurality of headphone measurement signals. In particular, the voltage values of the microphone signal and the earphone measurement signals recorded by the recording device may represent the voltage values of the microphone signal and the earphone signal actually measured by the electronic device 100 .

According to an embodiment of the present invention, the processor 130 first transmits a high potential control signal S1 (first control signal) to the fourth connection interface 220 through the second connection interface 120 . Next, the fourth connection interface 220 transmits the control signal S1 to the switching circuit 230 . When the switching circuit 230 receives the high potential control signal S1 , it couples the DC canceling circuit 250 to the signal generator 240 . According to an embodiment of the present invention, the signal generator 240 may be an RC oscillator. The signal generator 240 can generate an oscillating signal S2, and transmit the oscillating signal S2 to the DC elimination circuit 250, so as to eliminate the DC component of the oscillating signal S2. Next, the oscillating signal S2 with the DC component eliminated is sent to the voltage divider circuit 260 for voltage divider processing. The oscillating signal S2 after voltage division is transmitted to the first connection interface 110 through the third connection interface 210 . After the first connection interface 110 transmits the oscillating signal S2 to the processor 130, the processor 130 can obtain microphone information (or microphone path information) according to the microphone signal corresponding to the oscillating signal S2 and the oscillating signal S2 recorded by the recording device.

It should be noted that the voltage value of the headphone output signal S4 is still unknown at this time, that is to say, the obtained headphone information can be regarded as the voltage value of the headphone output signal S4. According to an embodiment of the present invention, each headphone output signal S4 corresponds to a detected sound source signal S3 in a different musical scale. The headphone output signal S4 is transmitted to the first connection interface 110 through the third connection interface 210 .

According to an embodiment of the present invention, each plurality of headphone measurement signals recorded by the recording device corresponds to a different headphone output signal S4, that is, each plurality of headphone measurement signals also corresponds to detected sound source signals S3 in different scales. For example, if the recording device records the earphone measurement signals corresponding to the detected sound source signal S3 in different scales, the voltage value of the earphone measurement signal is 600mV at the L0 scale; The value is 300mV; at the L2 scale, the voltage value of the earphone measurement signal is 100mV; at the L3 scale, the voltage value of the earphone measurement signal is 50mV, and the gain of the microphone is 2 according to the microphone information, the processor 130 can then A plurality of earphone measurement signals and microphone information recorded by the recording device, and the unknown voltage values (that is, earphone information) of the earphone output signal S4 corresponding to different musical scales are deduced to be respectively, when the L0 scale is used, the voltage value is 300mV; , the voltage value is 150mV; in the L2 scale, the voltage value is 50mV; in the L3 scale, the voltage value is 25mV.

According to an embodiment of the present invention, after obtaining the earphone information, the processor 130 can perform a security setting on the earphone playback setting of the electronic device according to the earphone information. For example, if the headphone information is the voltage value of the headphone output signal S4 corresponding to different scales, the voltage value is 300mV at the L0 scale; the voltage value is 150mV at the L1 scale; and the voltage value at the L2 scale is 50mV; in the L3 scale, the voltage value is 25mV, because the safe voltage is 150mV, therefore, the processor 130 will restrict the use of only scales with corresponding voltage values less than 150mV (ie L1-L3 scales). In addition, after the earphone playback setting of the electronic device 100 has undergone the security setting, no matter what type of earphone is used, the security setting is applicable. That is to say, after the earphone playback setting of the electronic device 100 has been set safely, each time the electronic device 100 uses the earphone to listen to the sound source signal, it does not need to be connected with the detection device 200 to perform the earphone playback of the electronic device 100 again.
