Transmission Loss of AYN-M80H300 acoustics membrane < 8dB @ 1KHz, and < 25dB in the whole frequency range.
AYN-M80H300
(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.
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 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.
All data above are typical data for the membrane raw material, for reference only, and should not be used as special data for outgoing quality control.
All technical information and advice given here is based on Aynuo’s previous experiences and test results. Aynuo gives this information to the best of its knowledge, but assumes no legal responsibility. Customers are asked to check the suitability and usability in the specific application, since the performance of the product can only be judged when all necessary operating data are available.
