Problems solved by technology

[0003] However, in this loudspeaker control method, the power of the loudspeaker output signal has been 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 relates to a loudspeaker control method and device. The loudspeaker control method comprises the steps of acquiring an input digital signal corresponding to an input audio signal; performing segmentation processing on the input digital signal to acquire a plurality of corresponding digital signal blocks; performing buffering processing on the digital signal blocks to acquire corresponding buffer signals; and carrying out gain adjustment on the buffer signals based on preset loudspeaker parameters so as to enable the structural performance parameters of a loudspeaker to be controlled within a preset range, wherein the preset loudspeaker parameters are operating state parameters of the loudspeaker when operating at a preset condition. The quality of audio signals outputted by the loudspeaker can be improved according to the scheme.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a speaker control method and device. Background technique [0002] The speaker is a transducer device that converts electrical signals into acoustic signals. The performance of the speaker has a great influence on the sound quality. Generally, when the power of the input signal is high, the speaker will generate nonlinear distortion or damage the diaphragm. In the prior art, the above situation is generally avoided by reducing the input signal power. [0003] However, in this loudspeaker control method, the power of the loudspeaker output signal has been 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. . Contents of the invention [0004] The technical problem solved by the embodiment of the present invention is ...
