摘　　要：音质,是扬声器的一个非常重要的品质指标。它同扬声器的其他各项参数一样,直接影响着听众对扬声器品质的客观评价。从物理学的角度讲,音调、响度、音色是构成声音的三大基本要素。音调,主要取决于声源振动的频率;响度,则取决于声源的有效振动面积、振幅和人距离声源的距离;音色,主要与发声体的材料、结构、发声方式等因素有关。它们共同决定了扬声器音质的好与坏。不同发声体发出的声音一般是不同的。要想从设计源头上控制好扬声器产品的音质,首先就要了解声音的三大基本要素,还要善于客观地评价扬声器产品的音质,更要深入探讨影响扬声器音质的主要因素。Tone quality is a very important quality index of loudspeakers. It has direct influence on audience＇s objective evaluation of the quality of loudspeakers as other parameters of loudspeakers. From the perspective of physics,pitch,loudness and timbre are the three basic elements of sound. Tone depends mainly on the frequency of the sound source. Loudness depends on the effective area of vibration,amplitude and the distance between audience and sound source. Timbre is mainly relative with material,structure,vibration types and other factors. They determine the sound quality of loudspeakers together. Different sound source have different sound. To control the loudspeaker tone quality,it is necessary to understand the three basic elements of sound,objectively evaluate the sound quality of loudspeakers and further explore the main factors influencing the sound quality of loudspeakers.
