Fever dynamic iron flavor electrostatic unit piezoelectric ceramic graphene diaphragm dual-cavity DIY earphone MMCX brushed titanium shell FNFB

Brand: DIY New piezoelectric ceramic flat head unit, stainless steel brushed titanium shell with fever sound quality, moving iron flavor, clear and pleasant to hear!! Stable parsing.. Standard MMCX. Wire piezoelectric unit is alternating voltage driving piezoelectric element with bottom metal substrate vibration sound, so in terms of response speed, piezoelectric unit is incomparable with moving iron and moving ring. The energy conversion steps of moving coil and moving iron are as follows: the current is converted into vibration under the action of magnetic field, and more energy is lost in the process. The Sound of piezoelectric is enough to be compared with the moving iron unit, because using metal sheet to make sound, the rigidity is good, which is the place that moving coil and moving iron can't do, so the definition and frequency are both 28 ohms higher than the unit impedance of moving coil. Bass is better than ordinary flat head, and the quantity is still so much..
