Embodiment 1
[0047] The embodiment of the present application provides a method for interface mode conversion, which is applied to the first electronic device. The electronic device includes an audio interface, and the interface module of the audio interface includes a conversion circuit. Please refer to figure 1 , the method includes:
[0048] S101: When a second electronic device is connected to the first electronic device through the audio interface, obtain first identification information used to indicate a type of the second electronic device.
[0049] In order to realize the diversification of the functions of the headphone jack, that is, the headphone jack can not only be used to plug in headphones, but also can be used to plug in other electronic devices. Therefore, the workflow of the headphone jack needs to be changed. Directly output the electrical signal required by the earphone in the case of earphone connection, but identify the access electronic device. Therefore, in the emb...

Abstract
The invention discloses a method for converting the interface mode and electronic devices. The method is applied to the first electronic device comprising an audio interface, and an interface module of the audio interface comprises a converting circuit. The method includes the steps that when the second electronic device is connected with the first electronic device through the audio interface, first identification information used for marking the type of the second electronic device is obtained; a first working current matched with the first identification information is obtained; whether a first output current of the audio interface is matched with the first working current or not is judged; if the first output current of the audio interface is not matched with the first working current, a converting instruction is generated; the converting instruction is executed, the first output current is converted into a second output current through the converting circuit so that the second output current can be matched with the first working current and the audio interface can be applied to a plurality of second electronic devices, and the utilization rate of the audio interface is improved.
Description
technical field [0001] The invention relates to the field of electronic technology, in particular to an interface mode method and electronic equipment. Background technique [0002] With the development of electronic technology, the same electronic device has more and more functions, and there are also more and more interfaces on the electronic device, such as multiple interfaces such as earphone jacks, gamepad interfaces, and mouse interfaces. [0003] In the actual application process, due to the increasingly thinner and thinner body design requirements of electronic equipment, the higher and higher appearance requirements, and the various interfaces not only occupy a large area, but also make the process of interface molding complicated, and also affect The aesthetics of the appearance of electronic devices. However, the earphone interface is small in size and easy to set up, so it can be flexibly applied to various electronic devices, ranging from MP3 players to desktop...
