Obviously, the described embodiments are some embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0019] The specific embodiments of the present application will be described in detail below in combination with the drawings.
[0020] Please participate Figure 1 、 Figure 2 The first embodiment of the present application discloses a start-up POP sound solving device, which comprises: an earphone sensing module and a start-up POP sound solving circuit. The first end of the earphone sensing module is used for electrical connection with the data end of a PC device. The second end of the earphone sensing module is used for connection with an earphone. The output end of the start-up POP sound solving circuit is electrically connected with the second end of the earphone sensing module. The control end of the start-up POP sound solving circuit is electrically connected with the output end of the PC device.
[0021] The start-up POP sound solving circuit is configured to turn on or turn off the second end of the earphone sensing module, so as to avoid the occurrence of POP sound when the PC device is started up in the case that the earphone has been inserted.
[0022] Preferably, the earphone sensing module adopts a model of SGM2549DYN6G / TR.
[0023] Specifically, in the present embodiment, the start-up POP sound solving device has two main components: an earphone sensing module and a start-up POP sound solving circuit. These components work together to ensure that the user will not hear any sudden, discontinuous sound when the PC device is started up. It is intended to solve the problem of the occurrence of POP sound in the start-up process in the case that the earphone has been inserted.
[0024] Specifically, the earphone sensing module is the core component of the device, the first end of which is electrically connected with the data end of the PC device, and the second end is connected with the earphone. This design allows the module to sense the insertion state of the earphone and adjust the working state of the circuit accordingly. The module adopts the model SGM2549DYN6G / TR, which is a earphone sensing chip that can automatically sense the grounding pole and select the correct grounding path, thereby avoiding the POP sound generated when the earphone is inserted.
[0025] The output end of the startup POP sound solving circuit is electrically connected with the second end of the earphone sensing module, and the control end is also electrically connected with the output end of the PC device. The circuit is configured to turn on or off the second end of the earphone sensing module to avoid the occurrence of POP sound when the PC device is started up with the earphone already inserted. By precisely controlling the power state of the earphone sensing module, the circuit ensures that even if the earphone is inserted when the PC device is started up, no audio interruption or POP sound will occur.
[0026] Please refer to Figure 3 , preferably, the startup POP sound solving circuit includes a control interface pin (GPIO1_L) and a third switch tube (AQ15), wherein the output end of the external PC device is electrically connected with the control end of the third switch tube (AQ15) through the control interface pin (GPIO1_L), the first end of the third switch tube (AQ15) is grounded, and the second end of the third switch tube (AQ15) is electrically connected with the second end of the earphone sensing module.
[0027] Preferably, the third switch tube (AQ15) is an NMOS tube, the control end of the third switch tube (AQ15) is the gate of the NMOS tube, the first end of the third switch tube (AQ15) is the source of the NMOS tube, and the second end of the third switch tube (AQ15) is the drain of the NMOS tube.
[0028] Specifically, in this embodiment, the startup POP sound solving circuit is set for the problem of POP sound occurring during the startup process when the earphone is already inserted. The control interface pin GPIO1_L is the key interface connecting the output end of the external PC device with the control end of the third switch tube AQ15. This pin can adjust the level state when the device starts up through the control level signal to control the working state of the third switch tube AQ15. The third switch tube AQ15 is an NMOS tube, the control end of which is the gate, the first end of which is the source ground, and the second end of which is the drain. This design enables the third switch tube AQ15 to respond quickly when the GPIO1_L level changes to control the power on / off of the earphone sensing module.
[0029] In the case of earphone insertion, during the boot process, the control interface pin GPIO1_L is pulled high by software control, at this time the third switch tube AQ15 will be turned on, its drain and the second end SLEEVE of the earphone sensing module are connected, at this time the second end SLEEVE of the earphone sensing module will be pulled low, and then the earphone sensing module is caused. This design ensures that when the system starts, the earphone interface will not have audio output and will not have output, and the POP sound will not be generated, avoiding the POP sound generated by the sudden connection of the power supply due to the start-up. Once the system startup is completed, the software can again pull the level of the control interface pin GPIO1_L low to make the third switch AQ15 closed, and the earphone sensing module returns to the normal working state, and the earphone can normally output audio.
[0030] In summary, the boot POP sound solving device significantly improves the user's auditory experience by precisely controlling the on-off state of the switch tube. It ensures that the user is not disturbed by the POP sound when the earphone is inserted and the system is started, and enjoys clearer and continuous audio output. In addition, the device is simple and efficient in design, easy to integrate into existing PC devices, does not require complex external control input, reduces manufacturing costs and improves product reliability. By using this specific switch tube combination and control logic, this device not only improves the compatibility of the earphone interface and the transmission quality of the audio signal, but also provides an innovative solution for the electronic technology field, with wide application prospects and commercial value.
[0031] The second embodiment of the utility model discloses a PC device, which comprises a device body and a boot POP sound solving device as any one of the above.
[0032] Preferably, it further comprises an indicator light module, wherein the output end of the device body is electrically connected with the input end of the indicator light module.
[0033] Specifically, in this embodiment, the indicator light module can be an LED indicator light, which is connected to the output end of the device body through electrical connection. When the device body detects a specific condition or error, such as a device malfunction or problem, the LED indicator light is controlled to produce corresponding light prompts; for example, rapid flashing may indicate that the device is initializing, while slow flashing may indicate that the device has encountered an error. This visual prompt provides an intuitive way for users to identify and respond to system status, enhancing user experience.
[0034] In addition, the LED indicator light is an ideal choice with its low power consumption, fast response and long life. In the embodiment, the LED indicator light is not only used to indicate the system status, but also to warn the user of possible abnormal conditions, such as data transmission errors, system overload or hardware failure.
[0035] It should be noted that in other embodiments, other types of indicator light modules can also be used, which are not specifically limited here, but these solutions are within the protection scope of the present application.
[0036] Preferably, it further comprises a sound warning module, wherein the output end of the device body is electrically connected to the input end of the sound warning module.
