Abstract

The invention discloses a live broadcast sound card voltage output control method and structure, and the method comprises the following steps: S1, obtaining a voltage input value signal of electric equipment, generating a reference feedback signal according to an input voltage value, and transmitting a control signal; and S2, controlling the connection or disconnection of a voltage regulation circuit according to the control signal so as to regulate the output voltage of the sound card. The structure comprises a receiving module which is used for receiving an input voltage signal of electric equipment; a comparison module which is used for generating a reference feedback signal according to the input voltage of the electric equipment and the output voltage of the sound card; and a controlmodule which is used for controlling each circuit switch in the adjusting module to be switched on or switched off according to the reference feedback signal so as to adjust the output voltage of thesound card. By adopting the technical scheme of the invention, the output voltage of the sound card can be adjusted according to the voltages of different electronic equipment connected with the soundcard when the working states are different, so as to meet the working voltage requirements of different electronic equipment.

Description

technical field [0001] The invention belongs to the technical field of power supply output, and in particular relates to a method and a structure for controlling the voltage output of a live sound card. Background technique [0002] The sound card is the most basic part of multimedia technology. It is a hardware that realizes the mutual conversion of sound waves / digital signals. Other equipment, while the live sound card is a hardware device that processes the digital signal through a program to obtain special effects sound on the basis of converting it into a digital signal. [0003] In the process of connecting the sound card with other devices, in order to meet the working voltage of the electronic product, it is necessary to output different working voltages according to the working voltage of the electronic product, so that the sound card can output a stable voltage and the electronic product can work normally. [0004] However, in the prior art, when electronic produc...
