Problems solved by technology

[0004] However, in this loudspeaker control method, the power of the loudspeaker output signal is always working below the rated power. Since the rated power is small, and most of the audio signals below the resonance frequency are filtered out, the quality of the audio signal output by the loudspeaker is poor.

Abstract

The invention discloses a loudspeaker control method and device. The method comprises the following steps: acquiring an input digital signal corresponding to an input audio signal; partitioning the input digital signal to obtain a plurality of corresponding digital signal blocks; performing buffer processing on the digital signal block to obtain a corresponding buffer signal; and performing gain adjustment on the buffer signal based on preset loudspeaker parameters, so that the structural performance parameters of the loudspeaker can be controlled within a preset range, and the preset loudspeaker parameters are working state parameters when the loudspeaker works under preset conditions. According to the scheme, the quality of the audio signal output by the loudspeaker can be improved.

Description

[0001] The application date is April 11, 2016, the application number is: 201610221282.7, and the name of the invention is a divisional application of the loudspeaker control method and device. technical field [0002] The invention relates to the field of communication technology, in particular to a speaker control method and device. Background technique [0003] Loudspeaker is a transducer device that converts electrical signals into acoustic signals. The performance of the loudspeaker has a great influence on the sound quality. Generally, when the power of the input signal is high, the speaker will produce nonlinear distortion or damage the diaphragm. In the prior art, the above situation is generally avoided by reducing the input signal power. [0004] However, in this loudspeaker control method, the power of the loudspeaker output signal is always working below the rated power. Since the rated power is small and most of the audio signals below the resonance frequency a...
