The 11×15×3.5 mm DONAU-WP is a high-end
miniature speaker of rectangular shape, specifi-
cally designed for waterproof applications in
portable devices, music phones and
smartphones where high quality sound is re-
quired. It delivers pure , uncolored sound re-
production in applications with small space.
Suitable for mono and stereo applications.
All materials used on the top surface of the
speaker are tested to be water resistant.
100% leak measurement guarantees IPx8 wa-
terproof compliance.
In addition to waterproof compliance this com-
ponent provides the same performance as the
standard DONAU speaker device (available
under part number 2403 260 00001).
