| 摘 要： | 利用控制变量法,研究了声源振幅、频率以及距离对声音接收器激发效果的影响。结果表明,振幅增大会使声音接收器激发效果值升高,但增速逐渐减缓;声源频率升高会使激发效果值先增大后减小,呈现"单峰性";声源和声音接收器间距离增大时激发效果值会逐渐降低。影响声音接收器激发效果的根本原因是声音的性质及声音接收器的结构特点。如果将研究成果合理应用能在"销"和"售"两方面激发市场的活力。

| Abstract: | Controlling variate method was used to study the relationships between sound receiver excitation effect and sound source amplitude,frequency and distance. The experiment results showed that the value of the excitation effect could be higher with the growth of sound source’s amplitude,but the growth gradually became slow. When the frequency got higher,the value of excitation effect increased firstly but then decreased,and appeared the phenomenon of single peak. The value of excitation effect decresed with the growth of distance between sound source and sound receiver. The root caused that determining the excitation effect were sound source characteristic and the structure of sound receiver.If the research results could be reasonably applied to the marketing and sold two aspects to stimulate the vitality of the market. |
