Murata says it has commenced mass production of its smallest waterproof piezoelectric speaker.
With a thickness of just 0.9 mm it is believed to be the world’s thinnest IPX7 speaker, said the supplier.
A feature of the design is that the speaker, designated VSLBG2216E, does not require any additional waterproof membrane to be applied during end-product manufacture.
"By using a piezoelectric element, without any magnet, ensures that the speaker is free of the ingress of metallic particles and has no electromagnetic noise that might affect other magnetic sensors that are incorporated into the product," said Murata.
Typical applications include mobile phones, tablet computers, e-book readers, digital cameras and portable music players.
