Audio harmonic distortion (TMD%)

There are a variety of speaker distortion, a common harmonic distortion (caused by the multi-speaker distortion field inhomogeneity and vibration system, often produced at low frequencies),Multimedia Speaker intermodulation distortion (due to the two signals of different frequencies while adding speakers, sound quality deterioration caused by mutual modulation) and transient distortion (due to the inertia of the vibration system can not keep up with changes in the signal changes, causing signal distortion) and so on. Multimedia Speaker When harmonic distortion is reproduced in harmonic components of the original signal not. Harmonic distortion of the speaker from the uniform magnetic field, the characteristics of the diaphragm, displacement of the coil of nonlinear distortion. Currently, the preferred harmonic distortion index of not more than 5% of speakers.
