Embodiment 1

[0027] Such as figure 2 As shown, the headphone noise cancellation method provided by Embodiment 1 of the present invention is applied to a terminal, and the terminal includes a headphone jack, and the method includes:

[0028] Step 21: Obtain the distance between the first preset position on the earphone plug and the second preset position on the earphone socket when the earphone plug is inserted into the earphone socket. The location of the contact.

[0029] The first preset position is preferably the non-connecting end of the earphone plug (the end for conflicting connection with the earphone jack), and the second preset position is preferably the end of the earphone jack (the bottom of the earphone jack).

[0030] Step 22: When the distance is less than or equal to the first preset value, turn on the microphone path on the headphone jack, otherwise, turn it off (trigger the headphone insertion interruption, control the bias voltage of the microphone to start power supply...

Embodiment 2

[0060] Such as Figure 6 As shown, the terminal provided in Embodiment 2 of the present invention includes an earphone socket, and further includes:

[0061] The sensor 61 is used to obtain the distance between the first preset position on the earphone plug and the second preset position on the earphone socket when the earphone plug is inserted into the earphone socket. The first preset position is preferably after the earphone plug is inserted, and Where the headphone socket contacts.

[0062] The first preset position is preferably the non-connecting end of the earphone plug (the end for conflicting connection with the earphone jack), and the second preset position is preferably the end of the earphone jack (the bottom of the earphone jack).

[0063] The conduction control module 62 is used to conduct the microphone path on the earphone socket when the distance is less than or equal to the first preset value, otherwise, it will not conduct (trigger the earphone insertion in...

Embodiment 3

[0076] Such as Figure 7 As shown, the terminal 700 provided in Embodiment 3 of the present invention includes:

[0077] At least one processor 701 , memory 702 , at least one network interface 704 and other user interface 703 . Various components in the terminal 700 are coupled together through a bus system 705 . It can be understood that the bus system 705 is used to realize connection and communication between these components. In addition to the data bus, the bus system 705 also includes a power bus, a control bus and a status signal bus. But for clarity, in Figure 7 The various buses are denoted bus system 705 in FIG.

[0078] Wherein, the user interface 703 may include a display, a keyboard or a pointing device (for example, a mouse, a trackball (trackball), a touch panel or a touch screen, and the like.

[0079] It can be understood that the memory 702 in the embodiment of the present invention may be a volatile memory or a nonvolatile memory, or may include both ...

Abstract

The invention provides an earphone noise elimination method and terminal. The earphone noise elimination method includes steps of obtaining a distance between a first preset position on an earphone plug and a second preset position on an earphone jack when the earphone plug is inserted into the earphone jack; and when the distance is less than or equal to a first preset value, performing conducting of a microphone path on the earphone jack, otherwise, not conducting. According to the technical scheme provided by the invention, the conducting of the microphone path on the earphone jack is performed when the distance between the first preset position on the earphone plug and the second preset position on the earphone jack is less than or equal to the first preset value to avoid generating of noise and the risk of poor contact in an earphone inserting and pulling process to improve the detection precision.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and a terminal for eliminating noise of earphones. Background technique [0002] With the rapid development of mobile terminals, there are more and more functions, and the life of users becomes more convenient. It has become an essential part of leisure life for users to use mobile terminals to play audio files or video files. Most of the time, users will use earphones to play. On the one hand, they can feel good sound quality, and on the other hand, they can avoid affecting other people. [0003] However, during use, the user will find that when the earphone is inserted or unplugged from the earphone socket, obvious noise will be heard. The noise generated by plugging or unplugging affects the user experience, and frequent noise can also affect the user's hearing. [0004] Specifically, the root cause of the noise is: such as figure 1 As shown, when the earphone ...
