ISL’s Piezo Ceramic Harsh Environment Speaker Features Extended Frequency Range

High-Efficiency Devices Meet Medical, Military, Portable and Industrial Design Specifications

Syosset, NY, June 25, 2018…Announced today by ISL Products International Ltd., a global leader in value-added manufacturing and engineering services for electronic/electromechanical components, is the PZ-94 harsh environment piezoelectric loudspeaker for broad frequency range applications.  Ultra-thin, small, and lightweight, the piezo ceramic loudspeaker may be driven by lightweight.  The speaker reproduces voice in the frequency response range of 450 HZ to 20 kHZ, and is tested to MIL-STD-810, method 509.1 (salt fog).  The PZ-94 loudspeaker system features a high-strength phenolic cone to provide resistance to humidity, external shock, and vibration, while the low dynamic mass of its drive mechanism enhances transient response.  As a piezo ceramic device does not generate an electromagnetic field, OEMs are further ensured their products meet all applicable EMC requirements and regulations.

Ideally suited for use in MRI suites and Department of Defense (DoD) applications, the speaker’s robust design, small form factor and ability to reliably perform in harsh environments makes the component equally appropriate in a variety of medical devices, transportation modes, portable, and industrial products.  It is commonly specified in outdoor, car audio, instrumentation, portable electronics, public address, and paging applications.  The PZ-94 is also applicable for producing ultrasound in sonarsystems.

In addition to featuring an extended frequency response range and tested towater resistance of coatings under a condition of 100% relative humidity,  the ruggedized PZ-94 offers a nominal power handling capacity of 50 W (EIA RS426) (8Ω system reference).  It has an average sensitivity rating of 82 dB @ 1W/1m, and typically appears as a 1.5 µF capacitor. The speaker measures 94 mm/3.70” in diameter with an approximate thickness of 15 mm/0.590”; weight is 33 g (1.1 oz.)

Delivery is from stock to 16 weeks, depending on quantity.
