Speakers and microphones

Our focus in this area is on sound sensors, loudspeakers and microphones in acoustics, with technologies for different purposes and environments. Flexibility in design and implementation provides a wide range of solutions that can have standard or custom sound characteristics.



Mini speakers can be customised for music or speech, for example, and are used in headsets, headphones, hands-free units, Bluetooth headsets, digital cameras and recording equipment. The most common are dynamic speaker elements in which a coil attached to a diaphragm moves in an air gap with a concentrated magnetic field.



A microphone is a sensor or transducer which converts sound to electric signals. There are many types of microphones, but nowadays microphones are mainly divided into two categories: dynamic microphones and condenser microphones. Both types generate signals from changes in the air pressure.
