The invention discloses a digital loudspeaker volume control method, device and equipment and a medium, relates to the technical field of loudspeakers, and is used for solving the problems of sound quality reduction and complex manufacturing process in the prior art. Comprising the steps of receiving a volume adjustment instruction; based on the volume adjustment instruction, determining an electric energy signal loaded to a loudspeaker unit in each path of quantized audio digital stream; the electric energy signal at least comprises an electric energy amplitude signal or an electric energy action time signal; and adjusting sound pulse energy output by the loudspeaker unit based on the electric energy amplitude or the electric energy action time to complete volume adjustment. According to the scheme, volume control of digital sounding is achieved based on the electric energy amplitude or the electric energy action time, a digital-to-analog converter is not needed, multiple transduction element hardware support is not needed, on the basis that the line number of transduction elements is not increased, the output sound pulse energy is controlled by controlling the electric signal energy loaded to the loudspeaker unit, and therefore the volume of the digital sounding is controlled. And digital volume adjustment is realized.
Description
technical field [0001] The present invention relates to the technical field of digital speakers, and in particular, to a method, device, device and medium for volume control of digital speakers. Background technique [0002] A 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. The speaker is the weakest component in the audio equipment, and it is the most important component for the sound effect. There are many types of speakers, and they vary widely in price. Audio electrical energy produces sound through electromagnetic, piezoelectric or electrostatic effects that cause its cone or diaphragm to vibrate and resonate (resonate) with the surrounding air. [0003] Digital sound is also sometimes called digital audio. Digital sound is a sound that uses digital technology to record, store, edit, compress, restore or play sound. It has the characteristics of convenie...
