In headphones area, there may have a variety of technology parameter, they are all concern with the hearing effect of a speakers. now let's put our eyesight a bit higher, to see the parameter of beats by dre studio, it is the leader in this area. To learn something about the phase distortion in portable headphone amplifier now.
To see the frequency range wholely, the phase distortion have its index, and evey headphones is not the same, some producer said they have the similar index parameter with some famous studio headphones in the market, while we should see the index they said comprehensively. the phase distortion can qualified from the passband at least. The experienced customers may know that there should need at least 5 times fourier changed and harmonic wave is all fine. it can ensure the original waveform is basicly accuracy ony by the status of every harmonic wave combined well. If this problem is talked at the situation of voice frequency portable headphone amplifier the frequency band should up to 200khz. but the problem is that if your element is not choosed well or circuit layout is not very perfect, the 200khz magnitude-frequency characteristic may not well done at last. at this time, it should take use of frequency compensation method. in the frequency condition at hundreds khz, the circuit and elements layout electric capacity and inductance will play role, and it may cause signal delay if the elements layout is not good. will the frequency compensation in phase distortion can solve this problem.
It still cann't layout a place out inside the open-loop amplifier to purpose well, we should take advantage of the detrimental feedback. With detrimental feedback, once the bad place out within of the open-loop circuit (phase qualities of bad), that offered how the shock came. Self-excited using the howling of course, that people all know, the strap can not straight listen to the self-excited, therefore, not be seriously. But truly it reflects the distortion within of the above here. offered how the shock is as well powerful band, the circuit of course, does not work. once the strap is not powerful amount of self-excitation, the circuit can work.
The theory may be as dry as a chip and it may difficult for a ordinary people to understand. so, the best way to choose a nice headset is wear a earphones on ear and feel it. the monster beats dr dre studio headphones we will suggest you to choose, it is rather good which features high definition in listening. feel it you can.
