2403 260 00098 SPEAKER-1115-4-SC-COBRA SF The 11x15x4 mm COBRA SF is high-end miniature speaker of rectangular shape with lateral sound outlets. Specifically designed for sidefiring applications, this speaker version enables a reduced application height in small, slim consumer devices, such as music phones, smartphones or tablet computers where high quality sound and maximum space efficiency are required. In addition, COBRA SF features Knowles’ advanced membrane technologies resulting in a state-of-the-art silicone membrane. This unique silicone membrane enables ultra-high excursion rates and superior robustness. Features: • Lateral sound outlet integrated in cover of speaker • Significant height reduction for side-firing applications • 100% in-line measurement of all specified acoustical and electrical parameters • Pre-tested and integrated side-porting acoustics • Manufactured to the highest standards • High power handling capacity of 1000mW This document contains information which is confidential and/or proprietary to Knowles Electronics, LLC or its affiliates.
