| 2403 260 00091 SPEAKER-1115-3.5-SC-COBRA The 11x15x3.5 mm rectangular COBRA speaker is a high end miniature speaker specifically designed for 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-theart silicone membrane. This unique Knowles silicone membrane enables ultra-high excursion rates and superior robustness. Features: • Maximum power handling capacity 1000mW • Unique Knowles silicone membrane providing ultra-high excursion for minimum THD, Q-factor and tumbling • Manufactured to the highest standards • 100% in-line measurement of all specified acoustical and electrical parameters Page 1 of 20 2011 Knowles Electronics 2403 260 00091 Contents Theory of Mechanical Layout and Main PWB Layout Spring Part Material Force on component Electrical and Acoustical Frequency response Electro-Acoustic Parameters Power Handling Measured Measurement setup Measurement adapter Environmental Environmental tests Qualification Reliability tests Sample Size, Sequence Period of Shelf-Life Testing Related Documents Change History Disclaimer Page 2 of 20 2011 Knowles Electronics 2403 260 00091 Theory of operation Cobra 11x15x3,5mm is an electrodynamic transducer, designed to translate electrical analog signals into sound. The input signal is fed into a coil in a magnetic field, which is attached to a membrane. Through the principle of the electromagnetic force, the membrane is moved according to the contents of the input signal.
