摘要
主要研究微电声器件的测试耦合腔与受话器前盖上带防尘网胶圈所形成的声阻之间特殊关系,对不同形式声阻尼的表现带来频响曲线的变化,从而得出耦合腔和受话器声阻设计不当或彼此不匹配,引起声压级的降低和音质表现力不足。
The special relationship between on the front cover with dust - proof net ring formed by the acoustic impedance and coupling cavity receiver test is researched. Changes to different forms of acoustic damping performance is brought to the frequency response curve. Thus the conclusion is drawn that the coupled cavity and receiver acoustic resistance of.poor design or do not match each other. A result of compressor to reduce and restrain sound quality performance.
