Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of electronic devices, and more particularly to a method for powering off an earphone and an electronic device. Background Art

[0002] With the gradual popularization of the universal serial bus Type-C (USB Type-C) interface (referred to as Type-C interface), more and more electronic devices have cancelled the analog headphone (such as 3.5mm headphone) interface, but the analog headphone has not withdrawn from the market. For example, electronic devices can be connected to the analog headphone through the Type-C interface to transmit audio signals to the analog headphone.

[0003] For electronic devices that support analog headphones or electronic devices that support analog headphones through the Type-C interface, when the analog headphones are unplugged from the electronic device, a sound similar to "puff" or electric current sound (this type of sound is called POP sound) is usually produced. The POP sound will greatly affect the user's experience of the electronic device. Therefore, how to reduce or eliminate the POP sound generated by unplugging is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The embodiments of the present application provide a method for powering off headphones and an electronic device, so that the headphones can be powered off quickly, thereby reducing or eliminating the POP sound generated by unplugging the headphones, which helps to improve the user experience of the electronic device.

[0031] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The terms "first", "second", "third", etc. in the embodiments of the present application are distinguished from different objects, rather than being used to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a series of steps or units are included, or alternatively, steps or units not listed are also included, or other steps or units inherent to these processes, methods, products or devices are also included.

[0033] For electronic devices that support analog headphones or electronic devices that support analog headphones through a Type-C interface, when the analog headphones are inserted into the electronic device, the probability of generating a POP sound is low because the electronic device has delays such as software startup in the power-on logic of the external headphone circuit module; however, when the analog headphones are unplugged from the electronic device, since audio and other signals are always in a communication state and unplugging is an instantaneous physical action, the probability of generating a POP sound is higher.

[0034] In view of this, the embodiments of the present application provide a method for powering off headphones and an electronic device, which can reduce or eliminate the POP sound generated by plugging and unplugging analog headphones without changing the circuit structure of the electronic device, thereby helping to improve the user experience of the electronic device. In other words, the POP sound can be reduced or eliminated without adding or reducing circuits.

[0035] In order to make the technical solution of the present application clearer, the application scenarios of the embodiments of the present application are first introduced below.

[0036] For example, see Figure 1 , is an example diagram of an application scenario provided by an embodiment of the present application. The application scenario may include an electronic device 100, a Type-C adapter 200, and a headset 300.

[0037] The electronic device 100 may be a mobile phone or a tablet computer; the electronic device 100 may also be a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), an augmented reality (AR) device, a virtual reality (VR) device, an artificial intelligence (AI) device, a wearable device, a vehicle-mounted device, a smart home device, and / or a smart city device; the electronic device 100 may also be a music player, a walkman, or other playback device. The embodiment of the present application does not impose any special restrictions on the specific type of the electronic device. Figure 1 The application scenario shown takes the electronic device 100 as a mobile phone as an example.

[0038] The Type-C adapter 200 includes a Type-C plug and an analog headphone jack, and the Type-C plug and the analog headphone jack are connected via a data cable. The Type-C plug fits with the Type-C interface and is used to be inserted into the Type-C interface of the electronic device 100; the analog headphone jack fits with the round plug of the analog headphone and is used to be inserted into the round plug of the analog headphone. After the Type-C plug is inserted into the Type-C interface of the electronic device 100 and the analog headphone plug is inserted into the analog headphone jack, the electronic device 100 is connected to the analog headphone, and then the electronic device 100 can transmit audio signals to the analog headphone.

[0039] The earphone 300 refers to an analog earphone, which can be understood as an earphone without a Type-C plug, or can be understood as a common cylindrical plug 3.5mm earphone. The analog earphone can be connected to the electronic device 100 via the Type-C adapter 200. The earphone involved in the embodiment of the present application refers to an analog earphone.

[0040] Figure 1The scenario shown in (1) is that the Type-C plug has been inserted into the Type-C interface of the electronic device 100, and the round plug of the headset 300 is about to be inserted into the analog headset jack. This scenario can be understood as a scenario in which the headset 300 is about to be inserted into the electronic device 100. In the embodiment of the present application, the headset 300 is inserted into the electronic device 100 by directly inserting the headset 300 into the 3.5mm headset jack of the electronic device 100 through its round plug, or the headset 300 is inserted into the Type-C interface of the electronic device 100 through the Type-C adapter 200.

[0041] Figure 1 The scenario shown in (2) is that the Type-C plug has been inserted into the Type-C interface of the electronic device 100, and the round plug of the earphone 300 is about to be unplugged from the analog earphone jack. This scenario can be understood as a scenario in which the earphone 300 is about to be unplugged from the electronic device 100. In the embodiment of the present application, the earphone 300 can be unplugged from the electronic device 100 directly from the 3.5mm earphone jack of the electronic device 100, or the earphone 300 can be unplugged from the analog earphone jack of the Type-C adapter 200, instead of the Type-C plug being unplugged from the electronic device 100.

[0042] That is to say, the embodiments of the present application can be applied to scenarios where headphones are directly plugged into or unplugged from electronic devices, scenarios where headphones are plugged into or unplugged from electronic devices via Type-C adapters, and scenarios where headphones are plugged into or unplugged from electronic devices via other types of adapters.

[0043] See also Figure 2 , is a schematic diagram of the pins of the circular plug of the analog headphone. The circular plug of the analog headphone includes four pins, which are pin SLEEVE, pin RING2, pin RING1 and pin TIP. Figure 2 As shown in (1), the SLEEVE pin is used for grounding, the RING2 pin is used for realizing the microphone function, the RING1 pin is used for realizing the right channel function, and the TIP pin is used for realizing the left channel function. Figure 2 As shown in (2), pin SLEEVE is used to implement the microphone function, pin RING2 is used for grounding, pin RING1 is used to implement the right channel function, and pin TIP is used to implement the left channel function. Figure 2 The bold lines in the figure represent the front view of the insulating ring.

[0044] The following is an introduction to the circuit structure diagram of the embodiment of the present application.

[0045] See also Figure 3 , is a schematic diagram of a circuit structure of an embodiment of the present application. The circuit structure is a partial circuit structure of an electronic device 100. Figure 3The circuit structure shown includes an audio module 301, an application processor (AP) module 302, an earphone module 303, an earphone interrupt signal module 304 and a total power supply V0305 of the audio module.

[0046] The AP module 302 can realize the functions of the AP, and the operating system, user interface, and application programs of the electronic device 100 are all executed on the AP. The AP module can be integrated on a system on chip (System on Chip, SOC).

[0047] The earphone module 303 is an earphone circuit module on the electronic device 100, outside the audio module 301, and is used to implement the function of the earphone circuit. The earphone circuit is used to power on or off the earphone. When there is power supply, the earphone circuit can power on the earphone; when there is no power supply, the earphone circuit can power off the earphone.

[0048] The earphone interrupt signal module 304 is a module on the electronic device 100 outside the audio module 301 and is used to provide a high-level or low-level earphone interrupt signal.

[0049] The audio module 301 may be an audio module inside an integrated circuit (IC) chip, which may be used to control the power on or off of the earphone module 303 to achieve the power on or off of the earphone. The IC chip may be a SOC, a power management unit (PMU), a power management integrated circuit (PMIC), etc. For the AP module 302 and the audio module 301 being integrated on the same SOC, the AP module 302 and the audio module 301 are independent of each other on the SOC, but may communicate with each other. The AP module 302 and the audio module 301 may also be integrated on different SOCs.

[0050] The total power supply V0 305 of the audio module is used to power the audio module 301. For the convenience of description, the total power supply V0 of the audio module is referred to as V0 below. V0 is used to identify the external power supply that supplies power to the entire audio module 301, and the external refers to the outside of the audio module or the IC chip where the audio module is located. V0 can be a PMU.

[0051] like Figure 3As shown, the audio module 301 includes a power supply V1 3011 inside the audio module, a software switch 3012, a hardware gate circuit 3013, a power supply V2 3014 for supplying power to the earphone module, a register 3015, and a resistor 3016. For the convenience of description, the power supply V1 inside the audio module is referred to as V1, and the power supply V2 for supplying power to the earphone module is referred to as V2.

[0052] V1 is used to identify the power supply after V0 enters the audio module, and V1 is used to supply power to the circuit or module inside the audio module. V2 is used to identify the power supply that supplies power to the earphone module 303. The opening or closing of the software switch 3012 is controlled by the AP control signal sent by the AP module 302. In other words, the AP control signal can control the opening or closing of the software switch 3012. When the software switch 3012 is turned on, a power path between V1 and the hardware gate circuit 3013 can be established, and then the hardware gate circuit 3013 can open the switch between V1 and V2 (including opening the switch for V1 input and opening the switch for output to V2), and then V2 can supply power to the earphone module 303. When the software switch 3012 is turned off, the power path between V1 and the hardware gate circuit 3013 is disconnected, and then the hardware gate circuit 3013 closes the switch between V1 and V2 (including closing the switch for V1 input and / or closing the switch for output to V2), and then V2 stops supplying power to the earphone module 303.

[0053] The hardware gate circuit 3013 is used to control the opening or closing of each switch according to the configuration information provided by the register 3015, for example, to control the opening or closing of the switch between V1 and V2, and is also used to feed back a high-level or low-level headphone interrupt signal to the AP module 302. The hardware gate circuit 3013 may include at least one of an AND gate circuit, an OR gate circuit, a NOT gate circuit, and the like. The hardware gate circuit 3013 may also include a comparator circuit, which is used to compare the headphone interrupt signal transmitted by the headphone interrupt signal module 304 with a reference signal to output a high-level or low-level headphone interrupt signal, and send the headphone interrupt signal to the AP module. It should be noted that the AP module is not powered by V1, but by other chips on the electronic device 100.

[0054] The register 3015 is used to provide configuration information to the hardware gate circuit 3013, so that the hardware gate circuit 3013 controls the opening or closing of each switch according to the configuration information. The configuration information provided by the register 3015 may include the configuration relationship between the various gate circuits of the hardware gate circuit 3013, so that the hardware gate circuit 3013 can control the opening or closing of each switch according to the configuration information. In the embodiment of the present application, the register 3015 can also receive an AP control signal from the AP module and modify the configuration information of the gate circuit based on the AP control signal.

[0055] The resistor 3016 is a pull-up resistor, one end of which is connected to V1 and the other end is connected to the headset interrupt signal module 304, so that V1 can provide a high level of power to the headset interrupt signal module 304. In this way, before the electronic device 100 is plugged into the headset, the headset interrupt signal module 304 generates and sends a high level headset interrupt signal. When or after the electronic device 100 is plugged into the headset, the power path between the headset interrupt signal module 304 and V1 is disconnected, and the headset interrupt signal module 304 is grounded, thereby generating and sending a low level headset interrupt signal. The headset interrupt signal can also be described as HP_EINT.

[0056] The following is based on Figure 3 The circuit structure shown introduces the processing process of inserting earphones into the electronic device 100 and the processing process of removing earphones from the electronic device 100.

[0057] See also Figure 4 , is a timing diagram of the processing process of the electronic device 100 being inserted into the earphone provided in the embodiment of the present application. Figure 4 The steps may include but are not limited to:

[0058] 401, the earphone interrupt signal module changes the earphone interrupt signal from a high level to a low level.

[0059] Before the earphone is inserted into the electronic device 100, the earphone interrupt signal module provides a high-level earphone interrupt signal and continues to provide a high-level earphone interrupt signal. When the earphone is inserted into the electronic device 100, the spring in the analog earphone jack of the electronic device 100 is short-circuited with the ground (Ground, GND), so that the earphone interrupt signal module changes the earphone interrupt signal from a high level to a low level. It can be understood that the physical behavior of inserting the earphone into the electronic device 100 causes the earphone interrupt signal to instantly change to a low level.

[0060] 402, the earphone interrupt signal module sends a low-level earphone interrupt signal to the hardware gate circuit.

[0061] The earphone interrupt signal module sends the low-level earphone interrupt signal to the hardware gate circuit, so that the hardware gate circuit sends the low-level earphone interrupt signal to the AP module. 403, the hardware gate circuit sends the low-level earphone interrupt signal to the AP module.

[0062] In response to the received low-level earphone interrupt signal, the hardware gate circuit sends the low-level earphone interrupt signal to the AP module.

[0063] 404. The AP module generates a first switch control signal.

[0064] In response to the received low-level headphone interrupt signal, the AP module generates a first switch control signal. The first switch control signal is used to control the software switch to turn on. The essence of the first switch control signal is the AP control signal. The AP module can recognize that the electronic device 100 is plugged into a headphone by changing from receiving a high-level headphone interrupt signal to receiving a low-level headphone interrupt signal.

[0065] 405 , the AP module sends the first switch control signal to the software switch.

[0066] The AP module sends the first switch control signal to the software switch in the audio module.

[0067] In response to the timer of the de-bouncing time timing out, the AP module sends a first switch control signal to the software switch to open the software switch, and then the hardware gate circuit can open the switch between V1 and V2. That is, after the timer of the de-bouncing time times out, the hardware gate circuit opens the switch between V1 and V2 to power on V2. In response to the timer of the de-bouncing time timing out, the AP module controls the opening of the software switch through the first switch control signal, which can reduce or avoid the POP sound generated by inserting headphones, making the power-on of V2 more stable. The AP module includes a timer for the de-bouncing time. In response to receiving a low-level headphone interrupt signal, the AP module starts the timer. The timing time of the timer reaches the rated time or the countdown time of the timer returns to zero, that is, the timer times out. The de-bouncing time of the AP module in different electronic devices may be different, but most of the de-bouncing times are within 250ms to 260ms.

[0068] 406, software switch is turned on.

[0069] In response to receiving the first switch control signal, the software switch is turned on to establish a power path between V1 and the hardware gate circuit. The power path between V1 and the hardware gate circuit includes a power path between V1 and the software switch and a power path between the software switch and the hardware gate circuit. When the software switch is turned on, the software switch is equivalent to a power conductor between V1 and the hardware gate circuit.

[0070] 407 , the hardware gate circuit opens the switch between V1 and V2 based on the first configuration information.

[0071] The first configuration information is obtained by the hardware gate circuit from the register. In response to the register writing the first configuration information, the register sends the first configuration information to the hardware gate circuit. The first configuration information includes a first configuration relationship between each gate circuit of the hardware gate circuit, and the hardware gate circuit can adjust the structure of the hardware gate circuit based on the first configuration relationship to open the switch between V1 and V2. In other words, the first configuration relationship enables the hardware gate circuit to open the switch between V1 and V2.

[0072] In response to the power path between V1 and the hardware gate circuit being established, the hardware gate circuit opens the switch between V1 and V2 based on the first configuration information.

[0073] Turning on the switch between V1 and V2 can be turning on the switch for V1 input and the switch for V2 output. Turning on the switch for V1 input can be understood as allowing V1 to input power to V2 through the hardware gate circuit; turning on the switch for V2 output can be understood as allowing power to be input to V2, so that V1 can input power to V2. Since the path between V1 and V2 is opened, V1 can supply power to V2, and then V2 can supply power to the earphone module, so that the earphone can be powered on.

[0074] 408. The software switch sends a switch status to the AP module, where the switch status indicates that the software switch is turned on.

[0075] In response to the software switch being turned on, the software switch sends a switch status to the AP module, indicating that the software switch is turned on.

[0076] After step 406, step 407 and step 408 may be performed. Step 407 and step 408 may be performed simultaneously.

[0077] 409. The AP module sends a first configuration control signal to the register.

[0078] In response to the received switch state indicating that the software switch is turned on, the AP module sends a first configuration control signal to the register. The first configuration control signal is used to instruct the register to update the configuration information, for example, to update the first configuration information to the second configuration information. The essence of the first configuration control signal is also an AP control signal, but its function is different from that of the first switch control signal. The first configuration control signal may include a control signal corresponding to the second configuration information so that the register updates its configuration information from the first configuration information to the second configuration information.

[0079] The second configuration information includes a second configuration relationship between each gate circuit of the hardware gate circuit, and the hardware gate circuit can adjust the structure of the hardware gate circuit based on the second configuration relationship to close the switch output to V2, and make the voltage signal of V2 change in the opposite direction to the voltage signal of the headphone interrupt signal. The reverse change includes the same change logic and opposite signal amplitude, that is, the voltage signal of V2 changes from a high level to a low level in the first time period after the headphone interrupt signal changes from a low level to a high level. The first time period is less than 40 microseconds.

[0080] 410. The register updates the first configuration information to the second configuration information.

[0081] In response to the received first configuration control signal, the register updates the first configuration information to the second configuration information. Optionally, the register deletes the first configuration information and writes the second configuration information.

[0082] 411. The register sends the second configuration information to the hardware gate circuit.

[0083] In response to writing the second configuration information into the register, the register sends the second configuration information to the hardware gate circuit, so that when the earphone is unplugged from the electronic device 100, the hardware gate circuit can control V2 to power off based on the second configuration information to reduce or avoid the POP sound generated by unplugging.

[0084] Figure 4 In the illustrated embodiment, when the power path between V1 and the hardware gate circuit has been established, the AP module also controls the register to update the configuration information so that when the earphone is unplugged from the electronic device 100, the POP sound generated by dialing out can be reduced or avoided.

[0085] For example, see Figure 5 The electronic device 100 is shown as a waveform diagram when headphones are plugged into it. Figure 5 In the figure, the voltage of the headphone interrupt signal is always high before the headphone is inserted, and immediately changes to low when the headphone is inserted; the voltage of V2 is always low before the headphone is inserted, and changes to high after a period of time (i.e., the time difference shown by the dotted line) after the headphone is inserted; the voltage of MIC_P is always low before the headphone is inserted, and changes to high after a period of time (i.e., the time difference shown by the dotted line) after the headphone is inserted. In other words, the change of the voltage of MIC_P is consistent with the change of the voltage of V2. Among them, MIC_P refers to the voltage in the analog headphone jack that is connected to the Figure 2 The time difference shown by the dotted line can be understood as the debounce time, and its value range is 250ms~260ms. Figure 5 Take 260ms as an example. The debounce time can also be understood as the delay time between V2 and the actual insertion time.

[0086] See also Figure 6 , is a timing diagram of the processing process of the earphone being unplugged from the electronic device 100 provided in an embodiment of the present application. Figure 6 The steps may include but are not limited to:

[0087] 601, the earphone interrupt signal module changes the earphone interrupt signal from a low level to a high level.

[0088] Before the earphone is unplugged from the electronic device 100, the earphone interrupt signal module provides a low-level earphone interrupt signal and continues to provide a low-level earphone interrupt signal. When the earphone is unplugged from the electronic device 100, the spring in the analog earphone jack of the electronic device 100 is separated from the GND, so that the earphone interrupt signal module changes the earphone interrupt signal from a low level to a high level. It can be understood that the physical act of unplugging the earphone from the electronic device 100 causes the earphone interrupt signal to instantly change to a high level.

[0089] 602, the earphone interrupt signal module sends a high-level earphone interrupt signal to the hardware gate circuit.

[0090] The earphone interrupt signal module sends the high-level earphone interrupt signal to the hardware gate circuit, so that the hardware gate circuit sends the high-level earphone interrupt signal to the AP module.

[0091] Updated to 603, the hardware gate circuit controls V2 to power off based on the second configuration information.

[0092] In response to the received high-level headphone interrupt signal, based on the second configuration information, V2 is controlled to be powered off, and the voltage signal of V2 changes in the opposite direction to the voltage signal of the headphone interrupt signal. Controlling V2 to power off may include: closing a switch output to V2 so that V2 can be powered off quickly.

[0093] 604, the hardware gate circuit sends a high-level earphone interrupt signal to the AP module.

[0094] In response to the received high-level earphone interrupt signal, the hardware gate circuit sends the high-level earphone interrupt signal to the AP module. In the embodiment of the present application, step 603 may be performed before step 604, or step 603 and step 604 may be performed simultaneously.

[0095] 605, the AP module generates a second switch control signal.

[0096] In response to the received high-level headphone interrupt signal, the AP module generates a second switch control signal. The second switch control signal is used to control the software switch to close. The essence of the second switch control signal is also an AP control signal. The AP module can recognize that the headphone is unplugged from the electronic device 100 by changing from receiving a low-level headphone interrupt signal to receiving a high-level headphone interrupt signal.

[0097] 606 , the AP module sends the second switch control signal to the software switch.

[0098] The AP module sends the second switch control signal to the software switch in the audio module.

[0099] 607, software switch is closed.

[0100] In response to receiving the second switch control signal, the software switch is closed to disconnect the power path between V1 and the hardware gate circuit.

[0101] 608, the software switch sends a switch status to the AP module, where the switch status indicates that the software switch is closed.

[0102] In response to the software switch being turned off, the software switch sends a switch status to the AP module indicating that the software switch has been turned off.

[0103] 609. The AP module sends a second configuration control signal to the register.

[0104] In response to the received switch state indicating that the software switch is closed, the AP module sends a second configuration control signal to the register. The second configuration control signal is used to instruct the register to update the configuration information, for example, to update the second configuration information to the first configuration information. The essence of the second configuration control signal is also an AP control signal, but its function is different from that of the second switch control signal. The second configuration control signal may include a control signal corresponding to the first configuration information so that the register updates its configuration information from the second configuration information to the first configuration information.

[0105] For the first configuration information, see Figure 4 The specific description of step 407 in the illustrated embodiment will not be repeated here.

[0106] 610. The register updates the second configuration information to the first configuration information.

[0107] In response to the received second configuration control signal, the register updates the second configuration information to the first configuration information. Optionally, the register deletes the second configuration information and writes the first configuration information.

[0108] The register updates the second configuration information to the first configuration information, which can be understood as restoring the configuration information to the initial configuration information (i.e., the first configuration information). In this way, the impact on the power-on of the headset can be reduced or avoided. If the second configuration information is not updated to the first configuration information, when the electronic device 100 is plugged into a headset, the headset may be burned out due to the rapid power-on of the headset.

[0109] 611. The register sends the first configuration information to the hardware gate circuit.

[0110] In response to the register writing the first configuration information, the register sends the first configuration information to the hardware gate circuit, so that when the electronic device 100 is plugged into the earphone, the hardware gate circuit can turn on the switch between V1 and V2 based on the first configuration information. Figure 6In the embodiment shown, since the hardware gate circuit detects a high-level headphone interrupt signal, it controls V2 to power down based on the second configuration information, so that V2 is powered down almost synchronously with the headphone interrupt signal being pulled high, so that the headphone is powered down at the first time it is pulled high. At this time, even if the headphone pin SLEEVE, the pin RING1 or the pin TIP is short-circuited with the GND in the analog headphone jack, no POP sound is generated. Thus, the POP sound generated by dialing out can be reduced or avoided.

[0111] If step 603 is not executed, but steps 604 to 607 are directly executed after step 602, that is, when the AP module detects a high-level headphone interrupt signal, it controls the software switch to close to close the gate circuit of V1 input, and then the hardware gate circuit controls V2 to power off. This process takes more than 2ms. For example, see Figure 7 An exemplary diagram showing an earphone being unplugged from the electronic device 100 is shown. Figure 7 In the example, the voltage of the headphone interrupt signal is always low before the headphone is unplugged, and becomes high after the headphone is unplugged. However, the voltage of V2 is high after the headphone is unplugged, and the high level is maintained for a period of time ( Figure 7 Take this period of time as 2ms as an example), and it will become a low level after this period of time. Within this 2ms, when the earphone is unplugged, if the earphone's pin SLEEVE, pin RING1 or pin TIP is short-circuited with the GND in the analog headphone jack, since the earphone has not been completely powered off, a POP sound will be generated.

[0112] For example, see Figure 8 The waveform diagram shown is when the earphone is dialed out from the electronic device 100. Figure 8 , the voltage of the headphone interrupt signal is always at a low level before being unplugged, and becomes a high level after a period of time after being unplugged; the voltage of V2 is always at a high level before being unplugged, and becomes a low level after a period of time after being unplugged. In other words, the change logic of the voltage of the headphone interrupt signal is opposite to the change logic of the voltage of V2. It can be understood that the voltage change logic of V2 is the same as that of the headphone interrupt signal, and the signal amplitudes are opposite. The same voltage change logic refers to changing the level of V2 within the first time period after unplugging, that is, the voltage of V2 becomes a low level within the first time period after the voltage of the headphone interrupt signal becomes a high level; the opposite signal amplitude refers to the opposite signal level, that is, the voltage signal of the headphone interrupt signal changes from a low level to a high level, and the voltage signal of V2 changes from a high level to a low level. Figure 8 The period of time indicated by the dotted line can be understood as the voltage change time of V2, and its value range is within 330 microseconds. Figure 8 Take 330 microseconds as an example. This value range is smaller than the value range of the debounce time, so it can effectively reduce the POP sound caused by unplugging, and even avoid any POP sound. Figure 8There is a slight delay between the voltage change of the headphone interrupt signal and the voltage change of V2, and the slight delay may be a first time period, and the first time period is less than 40 microseconds. The slight delay may be a delay in the processing of the comparator circuit in the hardware gate circuit.

[0113] contrast Figure 7 and Figure 8 It can be seen that after the voltage signal of the headphone interrupt signal changes from low level to high level, Figure 8 The high level of V2 lasts for 2ms before it turns to low level, which is much longer than Figure 7 The voltage change time of V2 is 330 microseconds, so the POP sound generated by dialing out can be effectively reduced or avoided by using the embodiment of the present application.

[0114] In the embodiments of the present application:

[0115] 1. V1 in the above embodiment can also be described as a first power source, and V2 in the above embodiment can also be described as a second power source. The second power source powering the earphone can be understood as V2 powering the earphone through the earphone module. Turning off the second power source can be understood as turning off the switch output to V2, and turning on the second power source can be understood as turning on the switch between V1 and V2 so that V1 supplies power to V2.

[0116] 2. The voltage of the headphone interrupt signal in the above embodiment can also be described as a headphone interrupt voltage signal. The first headphone interrupt voltage signal refers to a headphone interrupt signal that becomes a high level when the headphone is unplugged from the electronic device. The second headphone interrupt voltage signal refers to a headphone interrupt signal that becomes a low level when the headphone is plugged into the electronic device.

[0117] 3. The voltage signal of the second power supply changes in the opposite direction to the voltage signal of the earphone interruption. Figure 8 The waveforms shown are the voltage changes of V2 and the voltage changes of the headphone interrupt signal.

[0118] 4. Figure 4 The switch state of step 409 in the illustrated embodiment can also be described as a first switch state, Figure 6 The switching state of step 608 in the illustrated embodiment may also be described as a second switching state.

[0127] It is understandable that the interface connection relationship between the modules illustrated in the embodiment of the present invention is only a schematic illustration and does not constitute a structural limitation on the electronic device 100. In other embodiments of the present application, the electronic device 100 may also adopt different interface connection methods in the above embodiments, or a combination of multiple interface connection methods.

The application processor outputs a sound signal through an audio device (not limited to a speaker 170A, a receiver 170B, etc.), or displays an image or video through a display screen 194.
