Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] The terms "first", "second", "third" and "fourth" in the specification and claims of the present invention are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first USB signal, the second USB signal, the third USB signal, and the fourth USB signal are used to distinguish different USB signals, rather than describing a specific sequence of the USB signals.

[0022] It should be noted th...

Abstract

The embodiment of the present invention discloses a signal transmission device, a terminal and a signal transmission method, which are applied in the field of communication technology and can solve the problem in the prior art that terminals cannot recognize signals transmitted by certain USB devices. The method includes: receiving a first serial universal bus USB signal; when the voltage value of the first USB signal is not within a preset voltage range, converting the first USB signal into a second USB signal; the voltage of the second USB signal The value is within the preset voltage range. This method is applied in the scenario of transmitting USB signals.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a signal transmission device, a terminal, and a signal transmission method. Background technique [0002] With the popularization of terminal technology, terminal applications are becoming more and more extensive. The terminal can establish a USB connection with other devices (hereinafter referred to as USB devices) with Universal Serial Bus (full English name: Universal Serial Bus, English abbreviation: USB) function, so as to realize signal transmission with other USB devices. [0003] At present, in order to make the terminal compatible with more USB devices, a common-mode filter can be set inside the terminal to eliminate the interference signal in the USB signal received by the terminal, which can improve the signal quality of the USB signal received by the terminal , so that the terminal can recognize the USB signals sent by more USB dev...
