Onsia Technology

The Onsia™ Concealed Flat Panel Speaker is genuinely unique from all other forms of
electrical audio sound reproduction (most of which are based on the controlled motion of
a piston-like structure). Onsia utilizes the principle of distributed mode vibrations in a
lightweight rigid body.

Onsia works in much the same way as the majority of acoustic musical instruments —
utilizing the principle of a vibrating sound board or vibrating structural body. The entire
body of an acoustic guitar, for example, is a complex vibrating mass that radiates sound
energy in all directions. The strings of the acoustic guitar through the guitar’s bridge
function to excite or set off those vibrations. By themselves, the vibrations of the strings
contribute little to the acoustic energy radiated from the instrument; hence an electric
guitar does not make a great deal of sound without an amplifier.

In essence, Onsia speaker technology replaces the strings and bridge of an acoustic
musical instrument with a compact electromagnetic coil device, called a transducer. The
transducer is capable of converting electrical signals that carry the full audio frequency
bandwidth, into a small linear motion. The transducer is then used to “excite” a
soundboard. It is the soundboard itself, through a complex distributed mode vibrating
action, which then radiates large amounts of sound energy into the surrounding
environment without any perceived large excursion of a diaphragm.

Onsia vs Conventional Cone Speaker

Conventional speakers use a pair of magnetic fields to cause a membrane, or diaphragm,
to vibrate, thus creating sound. Onsia speakers, by contrast, use electronic impulses to
produce multiple vibrations across a single surface. When you tap a drum, the sound
vibrates across the drumhead, starting at the point at which you tapped. If you tap it
softly, the volume is lower. Tap along the edge, and you get a different tone than if you
tap the center. That’s the basic idea behind Onsia technology, but it goes one step further.
An electronic “exciter” on the back of each speaker sends electronic “taps” along the
surface of the panel. By changing and regulating each electronic tap, the exciter creates
different volumes and frequencies that vibrate through the panel. The resulting vibrations
are heard as sound. Onsia technology operates on a principle of complex vibrations
across an entire panel rather than the piston-like motion of a diaphragm.

NXT Technology

In the early 1990s, the British Defense
Ministry authorized the use of lighter, stiffer materials in the cockpits of fighter jets.
British fighter pilots complained about increased noise in the cockpit. When the
ministry’s scientists investigated, they discovered that the new materials carried the
plane’s own vibrations very efficiently —too efficiently for comfort. A London-based
company called NXT™ took the findings and conducted more research. In late 1997,
NXT began licensing technology for flat panel speakers. While flat speakers have been
around for nearly 50 years, NXT technology is the first to use multiple, chaotic vibrations
instead of a pulsating diaphragm to create sound. The result is an inexpensive,
lightweight and flexible speaker that can reproduce low, mid and high-range frequencies
better than conventional speakers. The first loudspeakers to utilize NXT technology
became available in 2000 marketed under the Benwin™ brand.
