Audio Parameters
耳机输出性能(3.5mm,蓝牙解码,LDAC)
Output Power L+R≥45mW+45mW(16Ω,THD+N<1%) Output Impedance ≤0.5Ω
L+R≥30mW+30mW(32Ω,THD+N<1%) Channel Separation ≥76dB
L+R≥3mW+3mW(300Ω,THD+N<1%) Signal-to-Noise Ratio ≥101dB(A-weighted)
*传统振膜通常依赖特定粘合剂将音圈粘合在振膜表面,这不仅增加振膜整体重量,还可能导致动圈运动时的动态失衡。局部重量分布不均会引起振动异常、改变振膜顺性,甚至因音圈擦圈而产生失真,最终影响单元整体表现。 <0.008%(1kHz/-3dB@32Ω) Noise floor ≤8uV(A计权)
Frequency Response 20Hz~20kHz:damping<0.5dB    
20Hz~45kHz:damping<2.3dB
