Embodiment Construction

[0056] The following is attached Figure 1-3 The application is described in further detail.

[0057] The embodiment of the present application discloses a high-temperature protection method for an audio system. The method can be applied in an audio control system. The audio control system can be a system that is applied to open and close audio equipment, adjust the output power of audio equipment, and other related operations indoors or outdoors. An audio control system can include a control center, a decibel meter, and multiple audio devices. Among them, the audio equipment is deployed in different positions in the preset audio work space, and preset sound receiving points are set in the preset audio work space. The preset audio work space can be indoor or outdoor, and the control center is responsible for To control the opening and closing of the audio equipment and the adjustment of the output power, the decibel tester is set at the preset sound receiving point, and the t...

Abstract

The invention relates to a sound equipment high-temperature protection method and system. The method is based on a sound equipment control system. The sound equipment control system comprises a control center and a plurality of sound equipment. The method comprises the steps that the control center periodically obtains feature information after a power amplifier in each sound device is turned on, wherein the feature information comprises the working temperature and the output power of the power amplifier; the method also includes comparing the working temperature of the power amplifier with a preset temperature threshold value; and when the working temperature of a certain power amplifier is not less than a preset temperature threshold, adjusting the output power of the power amplifier according to a preset power attenuation step length. The invention has the technical effect that the use experience of a user is improved.

Description

technical field [0001] The invention relates to the technical field of electronic products, in particular to an audio high temperature protection method and system. Background technique [0002] The power amplifier, referred to as the power amplifier, is one of the most basic components in audio equipment. Its main function is to amplify the weak electrical signal from the signal source to drive the speaker to play the sound. Audio equipment mainly includes audio host, power amplifier, receiving device and speakers, etc., which can play radio and recorded songs for users. [0003] In related technologies, when the audio equipment runs under load for a long time, the temperature of the power amplifier will also rise accordingly. When the built-in temperature sensor of the audio equipment senses that the temperature of the power amplifier has reached a preset temperature threshold, the audio equipment will start The built-in radiator for heat dissipation, and if the temperatu...
