2403 260 00132 SPEAKER-1115-3.5-SC-COBRA-WP The mm COBRA-WP is an advanced miniature speaker of rectangular shape, specifically is a high end miniature speaker specifically designed for waterproof applications in portable consumer devices, such as music phones, smartphones or tablet computers where high quality sound is required. It features Knowles’ advanced membrane technologies resulting in a state-of-the-art silicone membrane. This unique Knowles silicone membrane enables ultra-high excursion rates and superior robustness. 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 COBRA 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 • 1000mW maximum power handling capacity even at high ambient temperature • Unique Knowles silicone membrane providing ultra-high excursion for minimum THD, Q-factor and tumbling • Pre-loaded springs for mechanical robustness and easy handling • Multi-magnet system for improved sensitivity • Fully-automated manufacturing • 100% in-line measurement of specified acoustical and electrical parameters Page 1 of 21 2013 Knowles Electronics 2403 260 00132 Contents Theory of Mechanical Layout and Main PWB layout & electric polarity Magnetic polarity Spring force HNO3 test area Part Force on component Material Water/gas tightness Electrical and Acoustical Frequency response Electro-acoustic parameters Power Measured Measurement setup Measurement adapter Environmental Environmental tests Qualification Reliability tests Sample size, Period of Shelf-Life Testing Related Documents Change History Disclaimer Page 2 of 21 2013 Knowles Electronics 2403 260 00132 Theory of operation SPEAKER-1115-3.5-SC-COBRA-WP is an electrodynamic transducer, designed to translate electrical analog signals into acoustic waves.
