Method and device for outputting information

Abstract

The invention discloses a method and device for outputting information. The method for outputting information comprises the steps that a terminal detects the resistance between a microphone pin and a grounding line pin of an audio interface of the terminal and obtains a detection result; if the detection result is larger than 0 and smaller than or equal to 50 kilo-ohms, the information of external equipment inserted through the audio interface is output. According to the method and device for outputting information, the terminal detects the resistance between the microphone pin and the grounding line pin of the audio interface, if the detection result is larger than 0 and smaller than or equal to 50 kilo-ohms, the information of the external equipment inserted through the audio interface is output, namely the recognizable resistance range of the terminal is from 0 to 50 kilo-ohms, and relative to the existing recognizable resistance range of 3-30 kilo-ohms, 0-75 kilo-ohms and 0-100 kilo-ohms, the recognizable resistance range of 0-50 kilo-ohms can be compatible with most terminals, and the terminals can use the method of detecting resistance to determine whether the external equipment is inserted through the audio interface.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for outputting information. Background technique [0002] Terminals that support audio transmission (for example, mobile phones, PCs, tablet computers, etc.) are equipped with audio jacks. (for example, an audio key) is inserted, the terminal can transmit audio signals with the device. [0003] At present, all terminals have the function of automatically detecting whether there is an external device inserted through the audio interface. For the case of determining whether an external device is inserted through the audio interface by detecting the resistance value, the resistance value range of the audio interface that the existing terminal can recognize is generally 3 to 30 kohms, 0 to 75 kohms or 0 to 100 kohms, that is, when the terminal detects that the resistance between the microphone pin and the ground pin of its audio interface is in the above rang...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method and device for outputting information, to at least solve the problem that the range of recognizable resistance values ​​of the existing terminals is quite different and cannot be compatible with most terminals to determine whether there is an external device inserted through the audio interface by detecting the resistance value
