    NOTE:
    (1) Acoustic Response and IP Grade test part dimension: I.D. 2.0 mm / O.D. 6.0 mm.

    (2) The results are tested using a typical digital output MEMS microphone system and self-designed test device in AYNUO laboratory
    with representative sample size. The design of the device will affect final performance.

    Application

    This series of membranes can be used in waterproof and acoustics membrane for portable and wearable electronic
    devices, such as Smart Phone, Earphone, Smart Watch, and Bluetooth Speaker, Alertor etc.
    The membrane could provide the device with immersed waterproof protection and minimal sound transmission loss,
    keeping the device with the excellent acoustics transmission performance.

    Shelf Life

    Shelf life is 5 years from the date of receipt for this product as long as this product is stored in its original packaging in
    an environment below 80° F (27° C) and 60% RH.

    Note
