Preferably, the material of the flexible covers is non-woven fabrics or sheepskin.
Implement a kind of moving-coil type cone loudspeaker monomer of low distortion of the utility model, there is technology effect beneficial below
Fruit:
A kind of moving-coil type cone loudspeaker monomer of low distortion of the utility model takes the top drilling in dust cap, then
Hole is covered with flexible material, when sound wave and energy transmission are at the flexible material of dust cap aperture, since flexible material transmits
Speed is slow, greatly reduced sound wave and energy transmission, so that the sound wave at the top of dust cap intersects disorder and energy intersects wadding
It disorderly reduces, therefore the moving-coil type cone loudspeaker distortion factor decreases.
