Research on the Resonance Frequency of Headphone Speaker under Different Conditions

研究耳机扬声器在不同条件下的共振频率特性。基于理论分析和实验结果,首先讨论自由场中小扬声器自身网布对其f_(0)的影响;其次,分析小扬声器f_(0)在压力场和自由场条件下的差异,并进一步解释了压力场中f_(0)与频率响应的对应关系;最后,研究自由场中网布对大扬声器和小扬声器f_(0)的不同影响。

This paper studies the headphone speaker resonance frequency under different conditions.Based on the theory and experiments,the influence of the small speaker mesh on its free field f0 was analyzed.Besides,this paper studied the difference between the free field f0 and the pressure field f0,and then explained the relationship between the pressure filed f0 and pressure field sound pressure field.Lastly,the different influence of speaker mesh on different size speaker was also researched.
