Embodiment Construction

[0035] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0036] The solution of the embodiment of the present invention is mainly: by obtaining the voltage drop amplitude corresponding to the output voltage of the first power supply device of the terminal when the terminal RF power amplifier transmits a radio frequency signal, according to the voltage drop amplitude, determine the output voltage of the second power supply device of the terminal The compensation voltage amplitude corresponding to the compensation voltage, and then control the second power supply device to output the compensation voltage with the compensation voltage amplitude when the radio frequency power amplifier transmits the radio frequency signal, so that the total voltage output by the first power supply device and the second power supply device is constant, Therefore, the problem of voltage drop when ...

Abstract

The invention discloses an anti-howling method of a terminal. The terminal comprises a first power supply device for providing a working voltage, and a second power supply device for providing a compensation voltage. The anti-howling method of the terminal comprises the following steps: obtaining a voltage drop amplitude corresponding to an output voltage of the first power supply device when a radio frequency power amplifier of the terminal transmits a radio frequency signal; determining a compensation voltage amplitude corresponding to an output compensation voltage of the second power supply device according to the voltage drop amplitude; and controlling the second power supply device to output the compensation voltage at the compensation voltage amplitude when the radio frequency poweramplifier transmits the radio frequency signal, so that the total voltage output by the first power supply device and the second power supply device is constant. The invention further discloses a terminal and a computer readable storage medium. By adoption of the anti-howling method disclosed by the invention, the howling of the terminal is effectively prevented.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a terminal howling prevention method, a terminal and a computer-readable storage medium. Background technique [0002] With the development of science and technology, terminals such as mobile phones and PADs (tablet computers) have been widely used in recent years, and have become necessities in people's daily life and work. At present, in many scenarios, for example, when the user uses the terminal to make a call, the terminal RF power amplifier emits radio frequency signals, causing a voltage drop, which causes the capacitor components on the terminal motherboard to whistle and sound, which is commonly known as the current sound, affecting users. call effect. Therefore, terminal howling is an urgent problem to be solved. Contents of the invention [0003] The main purpose of the present invention is to provide a terminal howling prevention method, a terminal and a...
