AI Technical Summary

Technical Problem

Existing digital speaker volume control solutions suffer from reduced sound quality and complex manufacturing processes.

Method used

By receiving volume adjustment commands, the electrical energy signal loaded onto the speaker unit in each quantized audio digital stream is determined. The electrical energy signal includes the electrical energy amplitude or the electrical energy duration. The sound pulse energy output by the speaker unit is adjusted to achieve volume adjustment, avoiding the need for hardware support of digital-to-analog converters and multiple transducer elements.

Benefits of technology

It simplifies the manufacturing process, improves sound quality, and achieves digital volume adjustment by controlling the energy of electrical signals without reducing the signal-to-noise ratio.

Abstract

The application discloses a digital loudspeaker volume control method, device, equipment and medium, relates to the loudspeaker technical field, and is used for solving the problems of quality reduction and complex manufacturing process in the prior art. The method comprises the following steps: receiving a volume adjustment instruction; determining an electric energy signal loaded to a loudspeaker unit in each quantized audio digital stream based on the volume adjustment instruction; the electric energy signal at least comprises an electric energy amplitude signal or an electric energy action time signal; adjusting sound pulse energy output by the loudspeaker unit based on the electric energy amplitude or the electric energy action time, and completing volume adjustment. The scheme realizes volume control of digital sound production based on the electric energy amplitude or the electric energy action time, does not need a digital-analog converter, and does not need multiple transducing element hardware supports. On the basis of not increasing the number of rows of transducing elements, the electric signal energy loaded to the loudspeaker unit is controlled, so that the sound pulse energy output is controlled, and digital volume adjustment is realized.
