Technologies

NXT's technologies are unique and based on harnessing the natural modes of vibration in a panel to reproduce sound.  These technologies are derived from a profound understanding of bending wave physics and its applications to sound generation. 

NXT's vast intellectual property portfolio covers the fundamental principles together with numerous techniques for enhancement and optimisation as applied to various applications.

NXT's fundamental technologies are the Distributed Mode Loudspeaker (DML) and the Audio Full Range loudspeaker (AFR).  Common to both technologies is the ability to control and deal with the natural modes of a panel speaker system. DML provides techniques to turn almost any shape/size panel into a loudspeaker, whilst AFR confers specific solutions for circular panels.

In both cases, the loudspeakers exhibit some common features such as a broad frequency range, wide directivity and shallow form-factor. A direct benefit of such powerful features is to take complexity out of audio systems in today’s ever-increasing need for flatter/narrower/smaller loudspeakers.

Quite separately, and as a result of our core knowledge, NXT invented a unique touch screen technology using bending waves.  This technology has been exclusively licensed to 3M and is known commercially as Dispersive Signal Technology (DST).

NXT's latest announced technology again draws on our extensive experience in the field of bending waves.  A proprietary technology for touch screens and touch panels, Bending Wave Haptics delivers tactile feedback for users direct from a device's screen / interface.  Initially, the technology has been licensed exclusively to Nissha Printing Co., Ltd. of Japan for certain small touch screen applications for a period of at least three years.
