2403 260 00107 SPEAKER-1115-3.5-DONAU-WP The mm DONAU-WP is a high-end miniature speaker of rectangular shape, specifically designed for waterproof applications in portable devices, music phones and smartphones where high quality sound is required. It delivers pure , uncolored sound reproduction 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 waterproof compliance. In addition to waterproof compliance this component provides the same performance as the standard DONAU speaker device available under part number 2403 260 Features: • IPx8 waterproof tested in 1.5m for 30min. • Waterproof compliance 100% tested for each single speaker device • Excellent performance/price ratio • Flat, wide frequency response • Low resonance frequency 800Hz in closed back cavity • • Compound membrane for minimum THD, Q-factor and tumbling • Extremely robust spring connector • Fully-automated manufacturing Page 1 of 22 2013 Knowles Electronics 2403 260 00107 Contents Theory of Mechanical Layout and Main dimensions Pad layout & electric Magnetic polarity Spring force Part marking Force on component Material Water/gas tightness Electrical and Acoustical Frequency response Electro-acoustic parameters Power Measurement setup Measured Measurement adapter Environmental tests Qualification Reliability tests Sample size, Period of shelf-life Testing Related Documents Change History Disclaimer Page 2 of 22 2013 Knowles Electronics 2403 260 00107 Theory of operation SPEAKER-1115-3.5-DONAU-WP is an electrodynamic transducer, designed to translate electrical analog signals into acoustic waves.
