NBass™ Virtual Back Volume Technology Doubles the Effective Air Volume in Miniaturized Loudspeaker Systems

Vienna, Austria, February 21, 2012 – Knowles Sound Solutions has launched a sound enhancing technology to increase the acoustic performance in consumer devices with small form factors. N‘Bass™ stands for “enhanced bass“ and enables the smallest possible acoustic designs in smart phones, tablets and other portable media devices.

The patent pending N‘Bass™ Virtual Back Volume technology is a custom-developed material which increases the back volume seen by the loudspeaker by up to 100 %. It provides either better acoustic performance – specifically more bass – or smaller loudspeaker box designs while keeping the same performance. N‘Bass™ also facilitates the usage of bigger loudspeakers, thus providing superior sound performance within the same gross application volume.

“Consumers are demanding better sound performance for the multiple music, video, gaming, and telephone applications provided by the latest generation of smart portable devices,” said Ernst Müllner, President, Knowles Sound Solutions. "Due to the space gained by using N’Bass™, mobile phone and computing manufacturers have more flexibility to design solutions with superior sound and optimized space efficiency.”

Similar to a sponge, the N’Bass™ material adsorbs the air in the loudspeaker box. In this way, it virtually increases the available back volume for the loudspeaker. In addition, the material is non-conductive and has no negative influence on antenna performance.

The first smartphones to incorporate the technology have recently been launched by tier-1 handset OEMs and are currently in mass production. Knowles is the only supplier who offers this specific technology for miniaturized loudspeaker systems.
