[0046] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments.

[0047] Embodiment 1

[0048] This embodiment provides a headphone type recognition device, which is used to detect the type of a headphone based on a detection circuit. Among them, the detection circuit can be either a part of the headphone type recognition device or a part of a terminal device (i.e., a chip and a chip module product with headphone functions).

[0049] Figure 1 A schematic diagram showing the connection relationship between the headphone type recognition device and the headphone is schematically shown. Among them, the detection circuit includes: a power supply, a first pull-up resistor R2, and a second pull-up resistor R1. It should be understood that Figure 1 the headphone circuit is only schematically shown as an example, and the specific implementation form of the headphone circuit can be confirmed according to the actual situation.

[0050] The power supply is used to supply power to the headphone. The first pull-up resistor R2 is used to connect the power supply and the channel terminal of the headphone. The second pull-up resistor R1 is used to connect the power supply and the terminal to be detected of the headphone. In this embodiment, the first pull-up resistor R2 is connected to the left channel terminal. In other embodiments, the first pull-up resistor can also be connected to the right channel terminal.

[0051] Among them, the headphone type recognition device includes: a power register, a headphone plug detection register, and a type detection register.

[0052] The power register is used to trigger the power supply to supply power to the headphone.

[0053] In a specific embodiment, as Figure 1 shown, the power supply includes a main power supply VDDIO and a sub - power supply HEADMICBIAS. The main power supply is used to supply power to the earphone, and the sub - power supply is used to supply power to the terminal to be detected.

[0054] The power register includes a main - power register and a sub - power register. The main - power register is used to trigger the main power supply to supply power to the earphone, and the sub - power register is used to trigger the sub - power supply to supply power to the terminal to be detected.

[0055] In this embodiment, the power register is the main switch of the entire earphone, controlling the voltage of the entire earphone. The sub - power register is the sub - switch of the terminal to be detected, controlling the voltage of the microphone terminal. Only when the main - power register is turned on can the sub - switch of the microphone terminal take effect.

[0056] In this embodiment, the main - power register controls the power supply to the entire earphone. Based on this, the sub - power register controls the power supply to the microphone terminal. By this way of segmented control, the stability of the earphone type recognition device is improved, and it is also convenient to repair the device when a fault occurs.

[0057] In this embodiment, the earphone plug - in detection register is used to detect the first level between the power supply and the first pull - up resistor. Through the detection of the earphone plug - in detection register, it can be reflected whether the earphone is normally inserted into the terminal device. For example, when the signal detected by the earphone plug - in detection register is 1, it is confirmed that the earphone is normally inserted; when the signal detected by the register is 0, it is confirmed that the earphone is abnormally inserted.

[0058] The type detection register is used to detect the second level between the second pull - up resistor and the terminal to be detected. Among them, when the earphone is a three - segment earphone, the terminal to be detected is the ground terminal; when the earphone is a four - segment earphone, the terminal to be detected is the microphone terminal, that is, the MIC terminal. Through the detection of the type detection register, it can be reflected whether the earphone has a microphone terminal. For example, when the signal detected by the type detection register is 1, it is confirmed that the earphone has a microphone terminal, that is, the earphone is a four - segment earphone; when the signal detected by the type detection register is 0, it is confirmed that the earphone does not have a microphone terminal, that is, the earphone is a three - segment earphone.

[0059] In this embodiment, only a small number of registers need to be configured. That is, by configuring the power register to trigger the power supply to the earphone, by configuring the earphone plug - in detection register to detect the plug - in state of the earphone, and by configuring the type detection register, when the earphone plug - in detection register detects that the earphone is in the inserted state, it continues to detect whether the earphone has a microphone terminal. Thus, the specific type of the earphone can be judged through the detection signals of the registers. This embodiment does not require complex operations, and the specific type of the earphone can be detected by simply reading the values of a small number of registers, saving the detection time and reducing the detection cost.

[0060] In a specific implementation, the headset type identification device further includes a detection trigger register, which is used to trigger the opening of the type detection register.

[0061] In this embodiment, the activation of the detection trigger register is used as a prerequisite for the activation of the type detection register, so that the registers can be controlled step by step, which is convenient for the management of each register and for later debugging.

[0062] In a specific embodiment, Figure 1 As shown, 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 is grounded.

[0063] In this embodiment, by setting a buffer resistor, it is possible to avoid the earphone being burned out due to excessive voltage at the earphone end when the earphone is connected. By setting a capacitor, the stability of the first level between the detected power supply and the first pull-up resistor can be improved, so that the first level changes more slowly when the earphone is inserted or unplugged.

[0064] This embodiment also provides a method for identifying the type of earphones. The method for identifying the type of earphones is implemented based on the aforementioned device for identifying the type of earphones. Figure 2 As shown, the headphone type identification method includes:

[0065] Step 101, in response to the channel end of the earphone being connected to the detection circuit, triggering a power supply to supply power to the earphone through a power register;

[0066] Step 102, detecting a first level between a power source and a first pull-up resistor through a headphone plug-in detection register: if the first level is less than or equal to a first preset level, executing step 103;

[0067] 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, executing step 105; if the second level is greater than the second preset level, executing step 106;

[0068] Step 105, confirming that the type of the earphone is a three-stage earphone;

[0069] Step 106: Confirm that the type of the earphone is a four-band earphone.

[0070] In a specific implementation manner, step 102 may obtain a second detection signal of a headphone plug and unplug detection register. When the second detection signal is a third target signal, it is confirmed that the headphone has been plugged in, and step 103 is continued. When the second detection signal is a second target signal, it indicates that the headphone is not plugged in. Among them, the third target signal represents a signal whose first level is less than or equal to a first preset level, and the second target signal represents a signal whose first level is greater than the first preset level.

[0071] In a specific embodiment, step 103 has multiple ways to detect the type of the headphone. The following takes two specific ways as examples for illustration:

[0072] Way 1: Obtain a first detection signal of a type detection register. When the first detection signal is a first target signal, it indicates that the headphone is a three-section headphone. Among them, the first target signal represents a signal whose second level is less than or equal to a second preset level; if the detected first detection signal represents a signal whose second level is greater than the second preset level, it indicates that the headphone is a four-section headphone.

[0073] Way 2:

[0074] Obtain the first detection signal of the type detection register every first preset time;

[0075] When the number of the obtained first detection signals reaches a first preset number:

[0076] If the number of the first target signals in the obtained first detection signals is greater than or equal to a second preset number, confirm that the type of the headphone is a three-section headphone; if the number of the first target signals in the obtained first detection signals is less than the second preset number, confirm that the type of the headphone is a four-section headphone.

[0077] 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 signals is greater than or equal to the second preset number, confirm that the type of the headphone is a three-section headphone. If the aforementioned number is less than the second preset number, confirm that the type of the headphone is a four-section headphone. By this way, the situation that the accuracy of headphone type judgment is affected due to the unstable detection signal of the type detection register can be avoided, and thus the accuracy of headphone type judgment can be improved.

[0078] In a preferred embodiment, the first preset level can be determined according to the first pull-up resistor and the internal resistance of the headphone. Specifically, before the step where the first level is greater than or equal to the first preset level, the following steps are further included:

[0079] Determine the first preset level according to the first pull-up resistor and the internal resistance of the headphone.

[0080] In this embodiment, through the first pull-up resistor and the internal resistance of the earphone, the node for determining whether the earphone is inserted can be determined according to the actual situation, making the applicability of the earphone insertion judgment wider.

[0081] In a preferred embodiment, the second preset level can be determined according to the second pull-up resistor and the internal resistance of the earphone. Specifically, before the step that the second level is greater than or equal to the second preset level, it further includes:

[0082] Determine the second preset level according to the second pull-up resistor and the internal resistance of the earphone.

[0083] In this embodiment, through the second pull-up resistor and the internal resistance of the earphone, the node for determining that the earphone includes a microphone end can be determined according to the actual situation, making the applicability of the earphone type judgment wider.

[0084] To better understand this embodiment, the following is combined with Figure 1 , and is explained through a specific example:

[0085] In this example, a left-channel detection mechanism is specifically adopted (a right-channel detection mechanism can also be adopted in other examples). That is, when the earphone is inserted, the left channel L is connected to the first pull-up resistor, and HP_DET is the pin on the chip that triggers a hardware interrupt when the earphone is inserted. First, connect the first pull-up resistor R2 to the elastic piece in contact with the left channel of the earphone, pull up the voltage to 2.8v, and at the same time connect it to the HP_DET pin of the chip. At this time, since the earphone is not inserted, the GPIO (general-purpose input / output) pin corresponding to HP_DET is at a high level.

[0086] When the earphone is inserted, since the internal of the left channel of the earphone is equivalent to a 32-ohm resistor (the mainstream internal resistance of the earphone is 32 ohms, and there are also 8 ohms and 1000 k ohms. In this embodiment, an earphone with an internal resistance of 32 ohms is specifically used as an example for convenience of explanation) connected to GND (ground). Since the left-channel contact is connected to the GPIO pin corresponding to HP_DET and the impedance of the coil on the earphone is 32 ohms, the HP_DET pin will be pulled to a low level, causing a software interrupt. The internal comparator of the chip will generate an interrupt and update the status of the earphone plug-in detection register (update the value of the first detection signal RG_AUD_HEAD_INSERT to the first target signal 1). Since the left channel is at the innermost of the earphone socket, the insertion and removal of the earphone can be accurately judged.

[0087] Similarly, when the earphone is a three-section earphone, since the terminal to be detected is the ground terminal, when the three-section earphone is plugged in, the second level between the second pull-up resistor and the ground terminal is pulled down, thereby triggering the generation of the first target signal, from which it can be determined that the earphone is a three-section earphone without a microphone terminal; while when the earphone is a four-section earphone, since the terminal to be detected is the microphone terminal and it has a corresponding internal resistance, the second level between the second pull-up resistor and the ground terminal is relatively high, greater than or equal to the second preset level, so that it can be determined that the earphone is a four-section earphone with a microphone terminal.

[0088] In a specific implementation manner, step 102 may specifically include the following steps:

[0089] Obtain the second detection signal of the earphone plug detection register;

[0090] If the second detection signal is the second target signal, return to the step of obtaining the second detection signal of the earphone plug detection register at an interval of the second preset time until the second detection signal is the third target signal.

[0091] In this embodiment, if the second detection signal is the second target signal, it means that the earphone is not inserted into the terminal. In this case, the second detection signal of the earphone plug detection register will be obtained again 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 thus the accuracy of subsequent earphone type detection can be ensured.

[0092] In a specific implementation manner, before step 103, the step of enabling the detection trigger register may also be included.

[0093] In this embodiment, enabling the detection trigger register is used as a prerequisite for the type detection register to start detection, so that the registers can be controlled step by step, which is convenient for managing each register and also convenient for debugging it later.

[0094] To better understand this embodiment, the following is illustrated by a specific example:

[0095] After the earphone is inserted, initialize the registers, that is, enable the power register, sub-power register, earphone plug detection register, detection trigger register, and type detection register.

[0096] If the earphone plug detection register detects that the second detection signal is the third target signal, it is confirmed that the earphone has been inserted. If it detects that the second detection signal is the second target signal, it means that the earphone insertion state is unstable. Then, after waiting for 1 second, the second detection signal is detected again until the second detection signal is the third target signal before performing the subsequent steps.

[0097] Read the first detection signal of the type detection register every 1 millisecond. If the first detection signal is the first target signal, increment the value of the counter by 1. When the first detection signal is read 50 times, if the value of the counter is greater than or equal to 10, confirm that the earphone is a three-section earphone; if the value of the counter is less than 10, confirm that the earphone is a four-section earphone, and the earphone type detection is completed.

[0098] To save energy consumption, further, if it is confirmed that the earphone is a three-section earphone, then close the registers related to the detection microphone end, namely the power distribution register, the detection trigger register, and the type detection register.
