Abstract
The embodiment of the invention provides a conversion device, which comprises at least one plug, an USB jack and a conversion component, wherein a first pin of the plug is used for receiving a left sound channel signal; a second pin of the plug is used for receiving a right sound channel signal; a third pin of the plug is used for receiving a signal input by a pair of microphones or a ground signal output by equipment; a fourth pin of the plug is used for receiving the ground signal output by the equipment or the signal input by the microphones; the conversion component controls a first data terminal of an USB interface to be connected with the first pin, a second data terminal of the USB interface to be connected with the second pin, a user identification(UID) pin to be connected with the third pin for receiving the signal input by the microphones and transmitted to the equipment and a ground wire pin to be connected with the fourth pin for receiving the ground signal output by the equipment; or the conversion component controls the UID pin to be connected with the third pin for receiving the ground signal output by the equipment and the ground wire pin to be connected with the fourth pin for receiving the signal input by the microphones and transmitted to the equipment.
Description
technical field [0001] The invention relates to the field of electronic devices, in particular to a conversion device. Background technique [0002] At present, earphone plugs are mainly divided into two standards, one is the open mobile terminal platform standard, that is, the national standard, and the other is the mobile communication industry association standard, that is, the American standard. These two standards differ in the arrangement of the pins. . Figure 1a It is a schematic diagram of the structure of the American standard headphone plug. Pin 11 is used to output the left channel signal, pin 12 is used to output the right channel signal, pin 13 is used for grounding, and pin 14 is used to receive the signal input by the microphone. Figure 1b It is a schematic diagram of the structure of the national standard earphone plug. It also outputs the left channel signal from pin 11, the right channel signal from pin 12, grounds the pin 13, and receives the signal inpu...
