2403 260 00071 SPEAKER-1318-2.5-SC-GRAND The 13x18x2.5 mm Grand speaker provides maximum space efficiency and audio performance in small, slim consumer devices, such as mobile handsets or smartphones. The extremely flat speaker has the same space consumption compared to conventional 11x15x3.5 mm speakers but provides an improved acoustic performance resulting in a lower resonance frequency 750Hz and higher power handling capacity 600mW . An advanced triple magnet concept provides optimized acoustic sensitivity. Features: • Extremely slim design with only 2.5mm height • Low resonance frequency 750Hz • 600 mW power handling capacity • Triple magnet technology for improved sensitivity • Very robust spring connectors • 100% in-line measurement of all specified electrical and acoustical parameters Page 1 of 18 2011 Knowles Electronics 2403 260 00071 Contents Mechanical Layout and Main PWB Layout Top View Spring Force on component Part Material Electro-acoustic Frequency response Electro-Acoustic Parameters Power Measurement setup Measured Measurement Environmental Environmental tests Qualification Reliability tests Sample Size, Sequence Period of Shelf-Life Testing Related Documents Additional documents Change History Disclaimer Page 2 of 18 2011 Knowles Electronics 2403 260 00071 Mechanical Layout and Dimensions Main Dimensions Page 3 of 18 2011 Knowles Electronics PWB Layout Top View 2403 260 00071 positive voltage on pin + moves membrane in direction of arrow Page 4 of 18 2011 Knowles Electronics Spring Force 2403 260 00071 Force at Baskte level Force at Start Workingposition uncompressed delivery position Force at PPP level SPRING FORCE TABLE 0 mm 0,5 mm 0,65 +/- 0,15mm -0,2 mm max 1,2 N min 0,5N |
