Fraunhofer Spin-Off Develops Silicon Micro-Loudspeaker

Facebook X LinkedIn Email
DRESDEN, Germany, April 1, 2020 — The Fraunhofer IPMS spin-off company Arioso Systems GmbH has completed its first round of financing for its sound transducer principle for miniaturized headphones. Known as hearables, the micro-loudspeaker technology made from 100% silicon is based on the patented Nanoscopic Electrostatic Drive (NED) principle from Fraunhofer IPMS. Instead of a conventional membrane, the Arioso sound transducer membrane is installed inside the body of a silicon chip as a series of bending strips. New electrostatic actuators called Nano E-Drives are integrated inside the 20-µm-wide bending strips,...Read full article

    transducer
    A transducer is a device or component that converts one form of energy into another. It is commonly used in various fields, including electronics, acoustics, and instrumentation, to facilitate the measurement, detection, or transmission of information. Transducers are essential in converting signals from one domain to another for processing or interpretation. Key points about transducers include: Energy conversion: Transducers convert energy from one form to another. The input energy...
