N‘Bass™ stands for “enhanced bass“ and is a unique sound enhancing technology for miniaturized speaker systems developed by Knowles. Knowles offers this specific technology for miniaturized speaker systems. N‘Bass™ is a special material which increases the back volume seen by the speaker by up to 100% thus enabling either a better acoustic performance – specifically more bass – or smaller speaker box designs. It also enables the usage of bigger speakers with the same gross application volume. The N‘Bass™ material has no negative influence on antenna performance compared to conventional materials. Please contact us for more details

• N’Bass™ stands for ”enhanced bass”

• A unique sound enhancing technology increasing acoustic performance in small mobile devices (smart phones, tablets, ebooks, etc.)

• N’Bass™ doubles the effective back volume in miniaturized loudspeaker systems

MEMS microphones

Most of the Audio applications using loudspeakers uses also Microphones

and heretoo Seltech is global provider of Knowles SiSonic™ MEMS microphones. Knowles SiSonic™ MEMS microphones are designed with leading MEMS technology for stable acoustic performance under extreme conditions such as high temperature, shock and vibration. Seltech is global provider of these microphones.

Knowles SiSonic™ MEMS microphones are :

Omnidirectionnal

Surface Mount Devices (SMD)

with operating & storage temperature range from -40 °C to +100 °C

with either Analog or Digital output

with different RF immunity levels (standard, enhanced and maximum)

Knowles SiSonic™ MEMS microphones are available with either Top or Bottom sound port:

Top sound port: Bottom sound port:

The MEMS microphones with Bottom sound port (also called Zero Height MicTM) can shrink product thickness by up to 30%! They minimize the distance between PCB and device housing, enabling the very thin, high-density product designs. Knowles SiSonic™ MEMS microphones have integrated RF protection to help prevent RF noise from getting into the acoustic signal. All SiSonic™ MEMS microphones have a grounded Faraday cage integrated into the package. For the enhanced RF microphones, RC filters are built into the base PCB of the microphone. Maximum RF microphones are enhanced RF microphones with soldered metal-can packaging and a RF filtering built into the CMOS IC. Knowles SiSonic™ MEMS microphones are available with different package sizes:

Knowles’ state-of-art MEMS microphones are used in various applications such as cell phones, digital cameras, portable music players, smart phones, laptop computers, sensors, digital and other portable electronic devices.

Boom microphones & sensors

Knowles boom microphones are designed for either flexible or rigid

configurations and offer such performance options as noise rejection and high-frequency crossover of near and far field responses. Collaboration with commercial, governmental and industrial designers is producing new helmet applications for aircraft, military, first responder and high-noise manufacturing environments.

Headset booms allow the microphone to be placed in the near field, where a noise canceling microphone responds the difference in acoustic pressure. The combination of a good close-talking microphone element and close proximity to the mouth provides excellent signal to noise even in extremely noisy conditions. Those boom microphone assemblies are mainly used in :

Lightweight noise-canceling headset for telephony, computer speech recognition, or other indoor use (Security, Police, Fire, Dispatcher etc.)

Helmet or face mask integration

Radio communication (Aviation, Industrial, In-ear, Professional, Military)

And Sensor (Shot detection, Unattended Ground Sensors)

Several series of boom & sensor microphones are available : W, U, I, O, M, R, F and H W, U, I, O, M and R series are boom microphone assembly: W series – smaller footprint, lighter weight offering noise cancellation and IP67 rating I series – noise cancelling with self-powered microphone element M series – noise cancelling, waterproofing to IP68 rating R series – designed for aviation customers looking for TSO/RTCA compatible noise cancelling electret microphone W, O, M and R series are mainly built-in with EK, NR and WP specialty transducer microphones. U series are built-in with FG and DFG specialty transducer microphones. I series are built-in with BJ specialty transducer microphones.

F and H series are sensor microphone assembly: F series – Panel mount design for outdoor applications H series – Designed for use in outdoor sensor arrays for fixed or mobile installations. Detects time of arrival and acoustic signature for source triangulation and identification Both F and H series are built-in with highly sensitive EK or WP specialty transducer microphones.

Accelerometers, Ultrasonic, Dampers and Wax protection

Knowles’ sensors include accelerometers and ultrasonic sensors. Knowles’

accessories are acoustic dampers and wax protection.

Accelerometers are frequently used as contact microphones for radio communications in high noise environments such as firefighting or combat. The accelerometers reproduce voice signals from vibrations at the throat or from bony parts of the head, and are compatible with helmet or headset applications. Ultrasonic sensors are based on Knowles’ MEMS silicon surface mount microphone technology. While Knowles’ industry-leading MEMS silicon surface mount microphone technology, in bottom port configuration offer flat frequency response in the standard audio bandwidth, they are also capable to support even higher frequency bands. Sensor designs are possible across a wide spectrum of applications requiring highly miniaturized solutions for sensing and actuation/signaling. Acoustic dampers are acoustic cloth screens for insertion inside acoustic tubing. These damping elements are used between the receiver outlet and the ear canal to smoothen the frequency response. Wax protection prolongs hearing instrument performance. As the leading designer of hearing aid components, Knowles offers several ways for device manufacturers and end users to effectively address wax buildup. Solutions include WaxBuster and MicroWaxBuster push-piston wax removal systems, and NoWax disposable filter-replacement system.
