Tiny speakers can be inexpensively and quickly printed thanks to a combination of inkjet and laser technology, according to German scientists.
A demo component has been manufactured in a joint
project that brings together the Fraunhofer Institute for Laser
Technology ILT, the Institute for Materials in Electrical Engineering 2
(IWE2) at RWTH Aachen University and the Fraunhofer Institute
for Silicon Technology ISIT.
The tiny, hexagonal loudspeaker is cheap
to produce and the manufacturing method is digitally controllable
meaning instantaneous changes can be made to the design. This
lends the method to small batch production and could
allow a wider of range of companies to viably create loudspeakers.
