| 2403 260 00106 RECEIVER-612-2-SC-LEAN-WP The 6x12x2 mm LEAN-WP is an advanced miniature receiver of rectangular shape, specifically designed for waterproof applications in flat phones where wide-band quality sound and hearing-aid compatibility are required. 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 LEAN receiver component available under part number 2403 260 Features: • IPx8 waterproof tested in 1.5m for 30min. • Waterproof compliance 100% tested for each single speaker device • Designed for 3GPP wide band audio • Hearing Aid Compatibility HAC according to ANSI C3.19-2006 • Compound membrane for minimum THD, Q-factor and tumbling, and high power handling capacity • Fully-automated manufacturing • Pre-loaded springs for mechanical robustness and easy handling • 100% in-line measurement of specified acoustical and electrical parameters Page 1 of 20 2013 Knowles Electronics 2403 260 00106 Contents Theory of Mechanical layout and Main dimensions PWB layout & electric polarity Spring force on component Part marking / labeling Material Water/gas tightness Electrical and Acoustical Frequency response Electro-Acoustic Power Measurement setup Measured Measurement adapter Environmental conditions Environmental tests Qualification Reliability tests Test sequence sample size Period of shelf-life Testing Change Disclaimer Page 2 of 20 2013 Knowles Electronics 2403 260 00106 Theory of operation RECEIVER-612-2-SC-LEAN-WP is an electrodynamic transducer, designed to translate electrical analog signals into acoustic waves. The input signal is fed into a coil which is exposed to a permanent magnetic field and where a membrane is attached to. Through the principle of the resulting electromagnetic force, the membrane is moved according to the contents of the input signal and thus emitting sound by the air shifted.
