    Electrostatic Tweeter Thin Flat Electrets Flexible Loudspeaker EFL1014 ~ 2 Pcs with transformers
    Description
    EFL speakers are designed by 3-O LAB. The technology comes from Taiwan's ITRI original patent, providing ultra-clean, ultra-thin and ultra-high frequency output. The EFL's dual push-pull electret diaphragm design enhances the electric field strength between the stator and the spacer, resulting in high efficiency output, wide frequency range and no external bias.
    Principle of EFL
    •
    EFL
    is similar to an electrostatic loudspeaker, but uses “electrets” as its diaphragm.
    •
    Electrets has quasi-permanent electrical charges, needn’t add extra high voltage bias.
    •
    High voltage music signal connect to both side electrodes making electric field push-pull the diaphragm to generate sound, so it has bi-direction sound.
