SYDNEY, March 2, 2015 /PRNewswire/ -- Audio Pixels
Holdings Limited, the world-leader in MEMS based digital speaker
technologies, was pleased to announce today preliminary results
obtained from its extensive third phase measurement program. These
results not only substantiated the technology's advantages over
comparable analog speaker technologies, but exceeded the company's
own performance objectives. The results demonstrated sound pressure
levels (SPL) within the low frequency spectrum that were previously
believed by experts to be unattainable within a micro form factor;
measuring 80dB (decibels) at 250Hz[1] for a standalone chip.
The performance advantage delivers a 2-octave gain when compared
to micro speakers of similar size; comparable to music produced by
a piano missing 24 of its keys, the two-octave achievement restores
the body and depth of those missing keys. Additionally and unlike
traditional micro speaker technologies, Audio Pixels chips can be
cascaded in order to achieve virtually any desired performance
levels. By increasing the number of chips used it becomes possible
to cover virtually any application, from the smallest of mobile
devices to home theater applications and beyond. The chips do not
require any type of acoustic resonator or back chamber; in fact the
measurements were attained using wafer level chips. These
measurements validate just some of the advantages of Audio Pixels'
high performance digital speaker chips, such as low power
consumption, solder reflow compliant packaging, and innovative
digital drive algorithms.
Following his recent "standing room only" lecture on digital
speakers at the ALMA (Association of Loudspeaker Manufacturing and
Acoustic) International Symposium, the company invited Michael
Klasco, President of Menlo
Scientific, one of the worlds foremost experts in
loudspeakers, having his footprint
on many dozens of brand name speaker and acoustic products, to
review and validate the company's technologies, methodologies and
results. Mike summarized his visit as follows:
"This week I had the unique
opportunity to visit a MEMs semiconductor lab where the Audio
Pixels' team spends their time. Having the privilege to stick my
nose everywhere into this ambitious initiative, I can say that this
is one committed, passionate, and competent group of individuals.
This is the same sort of inspired approach and focused purpose that
eventually led MEMS microphone efforts to move from an industry
joke to total domination of the consumer electronics industry. The
Audio Pixels sound generation technique called Digital Sound
Reconstruction, differs significantly from conventional speakers in
that it appears able to deliver not only higher sound levels from
smaller size speaker devices, but also more extended low
frequencies (down to 250 Hz for a single chip) which is crucial for
wideband voice sound reproduction, an upcoming standard for phones.
This is exciting and game changing stuff."
In light of the results, the
company has already begun preparations for the launch of the fourth
and final phase of its productization plan. "This is a major
milestone for the company. We have exceeded our own targets set a
few years ago," says
Fred Bart, Chairman of Audio Pixels.
Yuval Cohen, the company's Chief Technology Officer
added, "The effort and success of this development phase has
afforded us extraordinary insight into the possibilities of digital
sound reconstruction, when combined with our unique micro scale
transducers. We now enter the final phase of product development
with the expectation of achieving even better performance
specifications."
