Waterproof piezo speaker

Featuring a thickness of only 0,9 mm, Murata has launched an ultra-thin, waterproof piezoelectric speaker. Based on proprietary piezoelectric technology, the speaker is waterproof to IPX5/IPX7. It measures 19,5 by 14,1 by 0,9 mm and its rectangular shape reduces dead-space from designs.
Conventional methods of waterproofing dynamic speakers used waterproof sheets which covered the output sound holes, reducing sound quality. Murata’s approach incorporates a rubber film into the speaker itself, leaving the output sound holes open. The width of the metal frame housing the speaker has been increased to improve the seal between the metal frame and the chassis, preventing water penetration.
The new waterproof speaker – the VSLBG1914E1400-T0 – features average sound pressure level (SPL) of 92,0 ±3,0 dB (1500 Hz/2000 Hz/2500 Hz/3000 Hz average) with a resonant frequency of 1400 Hz ±20%. Since no magnets are used, there is no possibility of malfunctions caused by iron sand, or electromagnetic effects on magnetic sensors.
