Abstract

The invention discloses a newly-defined micro USB (universal serial bus) interface, which solves the technical problems that the traditional micro USB interface is high in application cost, narrow in application range and poor in practicability. The newly-defined micro USB interface comprises a connector and a plurality of pins which are arranged on the connector side by side, wherein the pins include a power supply transmission pin, a ground wire transmission pin, an analog signal left channel transmission pin, an analog signal right channel transmission pin and a digital signal transmission pin. The transmission of the analog signal pin is added on the basis of the traditional single digital signal transmission, so that an analog signal can be transmitted while the digital signal is transmitted to using equipment, therefore the universality of the newly-defined micro USB interface is high in the signal transmission process. High integration degree and smallest size of the transmission signal also can be realized, the application cost is reduced, and the practicability is improved. The newly-defined micro USB interface has characteristics of wide application range, high practicability and low application cost.

Description

technical field [0001] The invention belongs to the field of electrical appliances, and relates to a micro USB interface, in particular to a newly defined micro USB interface. Background technique [0002] As a supporting device for electronic equipment, the micro USB interface is widely used in electronic equipment such as mobile phones, handheld computers, digital cameras, digital video cameras, and portable digital players. It is mainly used for digital signal transmission and charging. with attached figure 1 As shown, the micro USB interface in the prior art includes a connector and five pins arranged side by side on the connector, which are respectively GND, ID, D+, D- and VBUS from left to right, wherein the function of each pin As described in the table below: [0003] [0004] Among the five pins of the micro USB interface, data transmission is realized through the cooperation of GND, D+ and D-, and the signals they transmit are digital signals. When electronic ...
