CUI Devices


CUI Devices' Audio Group has announced the addition of several waterproof micro-speaker models which have an Ingress Protection (IP) rating of IP67.

The new parts in the CMS product family are housed in compact, lowprofile packages measuring as little as 15mm x 11mm. These waterproof speakers are ideal for portable and handheld electronic devices exposed to the moisture and contaminants found in industrial and outdoor applications.

These rectangular-frame models can produce a maximum soundpressure level ranging from 90dB to 93dB at a distance of 0.1m from the speaker.

All the new CMS parts offer spring-contact, solder-pad, or wirelead mounting styles. They are made with neodymium magnets and mylar cones for increased durability.
