摘要：This paper researched relationship between Power of adapter and total harmonic distortion of the open-type earphone. In the power of adapter, even harmonic component is extremeley less and only the odd harmonics component is found. When analysed THD of leaking sound open-type earphone far from 1m, as a result, even harmonic component was 2% and odd harmonic component was 35.5%. THD of the diaphragm was affected by THD of electric signal.
