Abstract

The invention discloses a sound box control method and device, relates to the field of electronic technology, and solves the problem that a sound box cannot be fundamentally avoided from damage caused by excessive high power by limiting the power of the sound box in the prior art. The method comprises that the proportion of high-frequency or low-frequency signals in input signals of the sound box within a preset time period is detected; the internal temperature of the sound box within the preset time period is detected; and when the internal temperature of the sound box is greater than a first threshold, and the proportion of the low-frequency signals is lower than a first preset proportion or the proportion of the high-frequency signals is greater than a second preset proportion, the power of the input signals of the sound box is decreased via control. the method and device are used for controlling the power of the sound box.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method and device for controlling a sound box. Background technique [0002] In daily life, many electronic products have built-in speakers. With the development of electronic technology, in order to better meet the needs of users, the volume of built-in speakers is constantly decreasing, such as televisions, laptops and other electronic products. It is becoming thinner and thinner. However, as the volume of the speaker decreases, its internal components are also continuously compressed, which reduces the rated power that the speaker can withstand, while the power requirements of the electronic product for the speaker are not reduced, which makes the electronic product The actual power of the speaker can easily reach the rated power it can withstand, which will cause damage to the speaker. [0003] In the prior art, the speaker is protected by limiting the power of the sp...
