Mini Sound Transducers Target Wireless Apps

The small, 9-mm diameter of the KST-911/-931/-951 ultra miniature sound transducers allows the devices to be used in a wide range of applications, including wireless communications, test equipment, and computers. The transducers come in either top or side port aperture styles and in two frequency ranges. And their operating voltage spans a 1V-2V to 4V-6V range at 70 mA.
