The invention provides a cabin independent sound area sound field adjusting system and method and a storage medium, the sound field adjusting system comprises a loudspeaker module and a sound field adjusting module, a loudspeaker in the loudspeaker module comprises two vibrating diaphragms, the two vibrating diaphragms are driven by the same sound channel signal, and the phase difference of sound signals output by the two vibrating diaphragms is 180 degrees. Through the design of the loudspeaker module, sound signals of adjacent seats in the same row in the cabin are mutually counteracted, and through the arrangement of the sound field adjustment module, a sound listening model of an independent sound area is established, the sound listening effect of each independent sound area is optimized, and the sound field adjustment of the independent sound area is realized. A sound field adjusting module in the system is provided with a storage medium for storing a computer program, and the program is used for executing the sound field adjusting method of the independent sound area of the cockpit.

    本申请提供一种座舱独立音区声场调节系统、方法和存储介质,声场调节系统中包括扬声器模块和声场调节模块,扬声器模块中的扬声器包含两个振膜,两个振膜由同一个声道信号进行驱动,两个振膜输出的声信号的相位差180°。通过扬声器模块的设计,实现了座舱内同排邻座的声音信号相互抵消,并通过设置声场调节模块,建立了独立音区的听音模型,优化各独立音区的听音效果,实现独立音区声场调节。本系统中的声场调节模块设置有存储计算机程序的存储介质,该程序用于执行座舱独立音区的声场调节方法。
