Knowles engineers and produces customized microphone designs for mobile consumer electronics, hearing aid applications, and emerging IOT devices.
The TO is the thinnest omni-directional microphone offered. Its small size is perfect for all applications, especially where space is an issue. The TO can also be used in directional applications as either a matched omni-directional pair, or in the TP series uni-directional / omni-directional pair. The BTO is an improved version of the TO microphone. It offers enhanced PFA performance, as well as power-on reset and an electrical high pass filter. The BTO is ideal in directional applications as a matched omni-directional pair.
The world's smallest balanced-armature receiver, the FK series is designed for CIC applications where minimum size and maximum fit rate is needed. Only 0.025cc in total volume, the FK receiver can provide over 123dB SPL output for even the tightest fittings and deepest insertions. The wide bandwidth version pushes the boundaries of high-frequency performance. As part of the TWFK receiver, the WBFK offers the widest bandwidth response of any receiver.
Highest performance dual balanced armature receiver, maximizing output per cubic millimeter while minimizing vibration and magnetic radiation. Ideal for mid-high power custom, BTE, and receiver-in-canal hearing instruments.
Form factors include a miniature design that can be immersed in water to a depth of one meter, and a bellows design for depths to 15 meters. The bellows design may be panel mounted, attached for boom applications and is suitable for outdoor use and repeated submersion.
