PUI Audio?'s ASE02506MS-LW90-DSM-R is a Dynamic Speaker Management (DSM)-Ready micro speaker that has been pre-characterized for use with Maxim's DSM smart amplifier solution. This DSM-Ready micro speaker comes prepackaged in a compact enclosure enabling easy system integration. This turnkey solution vastly increases the loudness (SPL) and bass response safely and reliably within our strict speaker specifications.

Reliability Testing

High Temperature Test

96 hours at +85 ºC ± 3 ºC followed by three hours in normal room temperature

Low Temperature Test

96 hours at -40 ºC ± 3 ºC followed by three hours in normal room temperature

Humidity Test

96 hours at +40 ºC ± 3 ºC with relative humidity at 90% ~ 95% followed by 6 hours in normal room temperature

Temperature Cycle Test

The part shall be subjected to 12 cycles using the following procedure:
Low temperature: -40 ºC±3 ºC
High temperature:+80 ºC±3 ºC
Cycle: 2 hours at High, 5 minutes High to Low, 2 hours at Low, 5 minutes Low to High

Vibration Test

10-55 to 10 Hz sine sweep, per minute at 1.5 mm amplitude 2 hours in each axis X, Y, and Z.

Drop Test

Mount speaker to 100 g fixture, drop fixture 1.5 meters, twice per side and twice for each corner.

Load Test

White noise is applied at the speakers rated power for 96 hours at room temperature with speaker in 1 cc enclosure.

Note for Reliability Testing

After each test, the speaker's SPL shall be ±3 dB of the original SPL.
