In a specific embodiment, as shown in fig. 1, the detection circuit further includes a buffer resistor R3 and/or a capacitor C1, wherein the buffer resistor is connected to the first pull-up resistor, one end of the capacitor is connected to the first pull-up resistor, and the other end of the capacitor is grounded.

The embodiment also provides a method for recognizing a type of a headset, which is implemented based on the device for recognizing a type of a headset, as shown in fig. 2, and the method for recognizing a type of a headset includes:
step 101, responding to the connection of a sound channel end of an earphone and a detection circuit, and triggering a power supply to supply power to the earphone through a power supply register;
102, detecting a first level between a power supply and a first pull-up resistor through an earphone plugging detection register: if the first level is less than or equal to the first preset level, go to step 103;
step 103, detecting a second level between the second pull-up resistor and the end to be detected through the type detection register: if the second level is less than or equal to the second preset level, go to step 105; if the second level is greater than the second preset level, go to step 106;
step 105, confirming that the type of the earphone is a three-section type earphone;
and 106, determining that the type of the earphone is a four-section earphone.
In a specific implementation manner, step 102 may obtain a second detection signal of the earphone plugging/unplugging detection register, when the second detection signal is a third target signal, it is determined that the earphone is plugged in, and step 103 is continuously performed, and when the second detection signal is a second target signal, it indicates that the earphone is not plugged in, where the third target signal represents a signal whose first level is less than or equal to the first preset level, and the second target signal represents a signal whose first level is greater than the first preset level.
In one embodiment, step 103 has a plurality of ways to detect the type of earphone, and two specific ways are exemplified below:
the first method is as follows: acquiring a first detection signal of the type detection register, and when the first detection signal is a first target signal, indicating that the earphone is a three-section earphone, wherein the first target signal indicates a signal of which the second level is less than or equal to a second preset level; if the detected first detection signal is a signal indicating that the second level is greater than the second preset level, the earphone is a four-section earphone.
The second method comprises the following steps:
acquiring a first detection signal of the type detection register at intervals of first preset time;
when the number of the acquired first detection signals reaches a first preset number:
if the number of the first target signals in the acquired first detection signals is larger than or equal to a second preset number, determining that the type of the earphone is a three-section type earphone; and if the number of the first target signals in the acquired first detection signals is smaller than a second preset number, determining that the type of the earphone is a four-section type earphone.
In this embodiment, the first detection signal of the type detection register is obtained multiple times, when the number of the first target signals in the first detection signal is greater than or equal to the second preset number, it is determined that the type of the earphone is a three-segment type earphone, and if the number is less than the second preset number, it is determined that the type of the earphone is a four-segment type earphone.
In a preferred embodiment, the first predetermined level may be determined according to the first pull-up resistor and an internal resistance of the earphone. Specifically, the step that the first level is greater than or equal to the first preset level further includes:
and determining a first preset level according to the first pull-up resistor and the internal resistance of the earphone.
In this embodiment, the node for determining whether the earphone is inserted may be determined according to an actual situation by the first pull-up resistor and the internal resistor of the earphone, so that the applicability of the determination of earphone insertion is wider.
In a preferred embodiment, the second predetermined level may be determined according to the second pull-up resistor and the internal resistance of the earphone. Specifically, the step that the second level is greater than or equal to the second preset level further comprises the following steps:
and determining a second preset level according to the second pull-up resistor and the internal resistance of the earphone.
In this embodiment, the node for judging whether the earphone includes the microphone end may be determined according to an actual situation by the second pull-up resistor and the internal resistor of the earphone, so that the applicability of the judgment of the earphone type is wider.
For a better understanding of the present embodiment, reference is made to the following description, by way of a specific example, with reference to fig. 1:
in this example, a left channel detection mechanism (or a right channel detection mechanism in other examples) is specifically adopted, that is, when the earphone is plugged in, the left channel L is connected with the first pull-up resistor, and the HP _ DET is a pin for triggering hardware interrupt of the earphone plugged in on a chip. First, a pull-up resistor R2 is connected to the elastic sheet of the earphone left channel contact to pull up the voltage to 2.8v, and at the same time, the HP _ DET pin of the chip is connected, and at this time, since the earphone is not inserted, the GPIO (general purpose input output) pin corresponding to HP _ DET is at high level.
When the earphone is inserted, since the internal resistance of the left channel of the earphone is equal to 1 32 ohms (the internal resistance of the earphone is 32 ohms, and also 8 ohms and 1000 kilo-ohms, the embodiment specifically takes the earphone with the internal resistance of 32 ohms as an example for convenience of description) and GND (ground) are connected. Because the left channel contact is connected with the GPIO pin corresponding to HP _ DET, the impedance of a coil on the earphone is 32 ohms, the HP _ DET pin is pulled to be low level, software interrupt is caused, and the internal comparator of the chip generates interrupt and updates the state of the earphone plug detection register (the value of the first detection signal RG _ AUD _ HEAD _ INSERT is updated to be a first target signal 1). Because the left sound channel is arranged at the innermost part of the earphone seat, the insertion and the extraction of the earphone can be accurately judged.
Similarly, when the earphone is a three-section earphone, because the end to be detected is a ground end, when the three-section earphone is connected, a second level between a second pull-up resistor and the ground end is pulled down, so that a first target signal is generated in a triggering mode, and therefore the earphone can be determined to be the three-section earphone without a microphone end; when the earphone is a four-segment earphone, the end to be detected is a microphone end and has corresponding internal resistance, and the second level between the second pull-up resistor of the second level and the ground end is higher and is greater than or equal to the second preset level, so that the earphone can be determined to be the four-segment earphone with the microphone end.
In a specific embodiment, step 102 may specifically include the following steps:
acquiring a second detection signal of the earphone plugging detection register;
and if the second detection signal is a second target signal, returning to the step of acquiring the second detection signal of the earphone plugging detection register at intervals of second preset time until the second detection signal is a third target signal.
In this embodiment, if the second detection signal is the second target signal, it indicates that the earphone is not inserted into the terminal, and in this case, the second detection signal of the earphone plugging/unplugging detection register is obtained again at every second preset time until the second detection signal is the third target signal, so that it can be determined that the earphone is inserted into the terminal, and accuracy of subsequent earphone type detection can be ensured.
In a specific embodiment, step 103 may further include the following steps: the detection trigger register is turned on.
In this embodiment, the start detection trigger register is used as a precondition for starting detection of the type detection register, so that the registers can be controlled step by step, each register can be managed conveniently, and debugging of the registers in a later stage is facilitated.
For a better understanding of the present embodiment, the following description is given by way of a specific example:
after the earphone is inserted, the registers, namely the power supply starting register, the power distribution register, the earphone plugging detection register, the detection trigger register and the type detection register are initialized.
And if the earphone plugging and unplugging detection register detects that the second detection signal is the third target signal, confirming that the earphone is inserted, if the second detection signal is the second target signal, indicating that the earphone insertion state is unstable, waiting for 1 second, detecting the second detection signal again until the second detection signal is the third target signal, and then executing the subsequent steps.
Reading a first detection signal of the type detection register every 1 millisecond, adding 1 to the value of the counter if the first detection signal is a first target signal, confirming that the earphone is a three-section type earphone if the value of the counter is more than or equal to 10 when the first detection signal is read for 50 times, and confirming that the earphone is a four-section type earphone if the value of the counter is less than 10, thus completing earphone type detection.
In order to save energy consumption, if the earphone is confirmed to be a three-section type earphone, registers related to the detection microphone end, namely a power supply register, a detection trigger register and a type detection register, are closed.
