Abstract

The invention discloses a loudspeaker and a method for playing a sound source, wherein, the loudspeaker comprises an encoding and decoding module, a power amplifier module, a loudspeaker module and a temperature detecting and processing module. The encoding and decoding module is used for transforming audio frequency data into a analog electronic signal to be gained; the power amplifier module is used for amplifying the analog electronic signal; the loudspeaker module is used for transforming the amplified analog electronic signal into a voice signal; and the temperature detecting and processing module is used for detecting the current operating temperature of the loudspeaker module and adjusting gain of the analog electronic signal according to the operating temperature. The loudspeaker and the method of the invention solve the problem that the loudspeaker for sound source output is easily burned out owing to high temperature, thus protecting the loudspeaker.

Description

technical field [0001] The invention relates to the communication field, in particular to a loudspeaker and a method for playing a sound source. Background technique [0002] At present, during the use of the multimedia terminal, it is often encountered that the speaker is burnt out, resulting in no sound during calls or playing audio sources. This problem is usually caused by the high power output of the speaker for a long time and the temperature is too high. [0003] Usually, the power amplifier will be calibrated before the terminal leaves the factory, and the phenomenon of long-term high-power output is not allowed. Therefore, the main reason for this problem is the problem of the sound source. [0004] The current audio sources are rich in formats and have various encoding and compression techniques. Even for audio sources of the same format, different files will have different built-in gains of the audio source. Therefore, this will result in the same volume level,...
