Abstract
The invention relates to a loudspeaker polarity detection method and device and a storage medium. The loudspeaker polarity detection method comprises the following steps: controlling a to-be-detected loudspeaker to output a target audio, and recording a target waveform corresponding to the target audio; determining a first waveform based on a source file of the target audio; and based on the first waveform and the target waveform, determining a polarity detection result of the to-be-detected loudspeaker. A to-be-detected loudspeaker is controlled to output a target audio, the waveform of the target audio is compared with the waveform in a source file, and whether the polarity of a loudspeaker access circuit is reversely connected or not is judged according to a comparison result. Therefore, automatic and simple operation of loudspeaker polarity detection by a user is realized, and the efficiency of loudspeaker polarity detection is improved.
