SYDNEY, March 3, 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 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."
