中文摘要:
      野战数字音响系统主要用于在各种复杂条件下的户外使用。该产品主要运用了D类功率放大技术、智能控制技术、触摸操控技术等。经过实验发现,在使用D类功率放大和经数字化处理后的声音在听感上存在生硬的感觉,为改善系统的听感,从产品研制的实际出发,对音频驱动器IRS2092增加了音色补偿电路,结合扬声器选用、滚塑音箱号角曲线设计与声相位的调试来综合提升野战数字音响系统的音质,使其能与传统场馆系统的音质媲美。
英文摘要:
      The field digital audio system is mainly used in various complicated conditions. This product integrates some advanced techniques such as D-class power amplifier, intelligent control and touch control. Experiments found that the sound has a stiff sense of hearing via D-class amplifier and digital processing. Starting from the actual situation of product development, a timbre compensation circuit is added in audio driver ISR2092, and by combining it with loudspeaker selection, horn curve design of rotational molding sound box and acoustic phase debugging, the sound quality of the field digital audio system is overall improved, so that the proposed digital audio system can match the sound-reinforcement system of traditional stadiums in sound quality.
