Company expands microphone portfolio to enable smaller, more
efficient devices
ITASCA, Ill.--(BUSINESS WIRE)--Jun. 2, 2015--
Knowles Corporation (NYSE: KN), a market leader and global supplier of
advanced micro-acoustic solutions and specialty components, today
announced that it has introduced the most advanced Inter-IC Sound, or
I²S, interface MEMS (Micro-Electro-Mechanical Systems) microphone for
wearables, remote controllers, automotive, and smart home automation and
security.
Knowles’ solution is superior in size and power consumption, with a 25
percent smaller footprint and 40 percent lower current consumption than
competitive products. Using this I²S interface, the bottom port digital
MEMS microphone allows manufacturers to connect directly to application
processors or microcontrollers. The result is a more efficient
architecture due to decreased complexity, increased battery performance,
and lower bill of material cost.
This innovation is especially important for space constrained devices
such as wearables, which have a very small board size that puts a
premium on component space. The new technology easily integrates with
existing mobile device architecture and simplifies system integration
through a direct connection to signal processors.
“Knowles’ is committed to advancing audio solutions and our
customer-focused approach to creating meaningful technologies,” said
Thibault Kassir, Senior Director, Product Management, Mobile Consumer
Electronics. “This innovation is our first step toward providing
intelligent audio solutions and establishes a solid foundation for our
future roadmap.”
"Our expertise in acoustics and audio systems drove the development of
the world’s most advanced I²S MEMS microphone,” said Bertrand Renaud,
Product Management, Mobile Consumer Electronics. “We developed this
intelligent audio solution to support the growing demand for smaller,
more efficient devices and we are enthusiastic to see the solution
already adopted on wearable reference designs and selected by several
consumer electronics customers with shipments beginning in the third
quarter.”
