Problems solved by technology

The existing passive radiator is assembled inside the cavity by glue coating and other processes. When the passive radiator is vibrating, if the low-frequency driving force of the speaker is too large, the passive radiator will hit the shell and generate noise.

Abstract

The invention discloses a sound effect control method which is applied to sound box equipment, a metal plate corresponding to a metal balancing weight of a passive radiator is arranged on the inner side of a shell of the sound box equipment, and the sound effect control method comprises the steps that constant voltage is applied to the metal plate and the metal balancing weight; an audio signal is sent to a loudspeaker, and the passive radiator is driven by using the loudspeaker; a current capacitance value between the metal plate and the metal balancing weight is obtained, and the state of the passive radiator is determined according to the current capacitance value; and if the passive radiator is in the collision critical state, a low-frequency suppression instruction is sent to the loudspeaker, so that the low-frequency output voltage of the loudspeaker is not increased any more. The passive radiator can be prevented from hitting the shell to generate noise, and the audio playing quality of the loudspeaker box is improved. The invention also discloses a sound effect control device, sound box equipment and a storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the technical field of audio processing, in particular to an audio effect control method and device, a speaker device and a storage medium. Background technique [0002] In recent years, smart speaker products have developed rapidly. With the increase of smart home products and the rapid development of 5G communication, smart speakers, as an important human-computer interaction portal of the Internet of Things, have huge development potential and market demand in the future. Compared with traditional speakers, in order to meet various usage scenarios and user experience, smart speakers need to integrate more functional modules in a smaller volume, and the contradictory relationship between cost and acoustic performance is often more prominent than traditional speakers. To obtain optimal acoustic performance in a limited space while reducing costs, many smart speakers use a combination of full-range speakers and passiv...
