The company's deep experience and rigorous testing delivers consistently dependable and precise products including speakers and microphones for hearing health products, premium music earphones, communications headsets, and industrial acoustic applications. Knowles MEMS (micro-electro-mechanical systems) microphones and micro-speakers are widely used in smartphones, tablets, notebooks, and other portable devices. The Knowles Quality Management System ensures design, integrity, efficient manufacturing and the cost effective on-time delivery of their products.
Knowles SiSonic™ FLEX Evaluation Kit allows for simple and easy evaluation of SiSonic MEMS microphones. This evaluation system can be used to evaluate up to two channels of audio for digital MEMS microphones along with one channel of audio for analog MEMS microphones. One DAC PCB board, three Adapter PCBs, and ten Mic-On-Flex Assemblies are included in the evaluation kit. The power supply (AC Adapter) and headset are offered separately.
Knowles WP Series Waterproof Omnidirectional, Noise Canceling
Microphone can survive immersion in 1m of water. The WP Series’ form
factor is a very small size with low vibration sensitivity. The
excellent noise canceling performance is useful for sensors and
Knowles EK Omnidirectional Microphones provide a unique
combination of size, performance and value. Their high electroacoustic
sensitivity and low noise make them excellent choices for applications
where space allows. These popular microphones are available in many
Knowles FG Series Microphones are among the world's smallest electret
condenser microphones. Their cylindrical shape and compact size
facilitate compact designs. The FG can also be used in directional
applications as a matched omni-directional pair.
Knowles EA Series Microphones were introduced in 1976, and are a time-tested electret condenser
microphone. They are widely used in more cost sensitive applications.
Knowles Piezo Ceramic Microphones BL Series are rugged, stable
and versatile. BL microphones are available in three different package
sizes: standard, thin or 0.5" cylindrical shell and cable assembly. Both
communication and broadband frequency response versions are offered. In
addition, BL microphones have high vibration sensitivity and may be
used as accelerometers.
Knowles SP Series SiSonic MEMS Silicon Microphones are miniature, high-performance, low power, top port silicon digital microphone. Using Knowles' proven high performance SiSonicTM
MEMS technology, these digital microphones consist of an acoustic
sensor, a low noise input buffer, and either a sigma-delta modulator or
output amplifier. These devices are suitable for applications such as
cellphones, smart phones, laptop computers, sensors, digital still
cameras, portable music recorders, and other portable electronic devices
where excellent wideband audio performance and RF immunity are
SiSonic™ Microphone Series, built on Knowles CMOS/MEMS technology platform, is in the fourth generation of development. The series supports high-performance design in cell phones, digital cameras, and other portable devices. New MaxRF models eliminate GSM/TDMA burst noise and provide wide-band RF suppression. The 4th generation SiSonic Microphones from Knowles offer smaller sizes, lower profiles and mounting options, increased output, and new digital noise-eliminating audio options.
Knowles Subminiature Performance Microphones feature magnetic, piezo ceramic and electret condensers with low noise and RF filtering. Ideal for new product ideas that require premium audio and very small form factor solutions.
Knowles Subminiature Speakers feature a balanced armature technology with magnetic technology, high efficiency, stability, and reliability for a variety of high performance audio and communication products. Ideal for premium in-ear designs, as well as component and subassembly solutions.
