1 DD + 4BA configuration •Hybrid three frequency division The physical band-pass and low-pass filtering of the sound duct structure relying on 3D printing to form a hybrid three-frequency structure, which is divided by the RC power frequency division. Dual Knowles’ SWFK high-frequency balanced armature unit is responsible for high-frequency. A pair of exclusive custom IF units are for mid-frequency (to achieve VDSF Target Frequency. Response) A 10mm dynamic coil unit of a paper cone composite diaphragm is for low-frequency. All for the transparent sounds with deep bass, middle pitch, and sweet treble.
Scientifically effective and unpretentious configuration The configuration of 1 DD and 4BA efficiently utilizes the acoustic characteristics of dynamic and armature hybrid. Unlike the blind stacking together, Blessing2's configuration is simple, reasonable, and efficient. A custom full-frequency composite balanced armature is responsible for the mid-frequency, and it is used in the 500Hz-80004 frequency band that meets the VDSF Target Response in conjunction with the circuit and filtering conditions, which guarantees the quality and dynamic density. For the high-frequency, this earphone adopts the American Knowles SWFK with low distortion and excellent high-frequency bandwidth to match the mid-frequency sensitivity. With excellent low frequency response, quality index and hearing sense, 10mm diameter paper cone diaphragm dynamic coil unit is used for low-frequency, and its use efficiency at low frequency is much higher than any of them.
