Flexure size : 0.167*0.531 inch
Description of speaker:
The speaker is make up of two piezo and one piece of stainless steel,
and we will use epoxy to joining them together.
Application :
The speaker systems represent a breakthrough in audio technology
that delivers unparalleled audio performance from a zero footprint package.
With the unique ability to create a fullytransparent speaker
that offers amazing sonic performance,
it has developed Edge Motion audio systems for display-based applications.
These speaker systems transform the screen of a flat panel display product
from TVs and computer monitors to laptops and DVD players into a fully-integrated,
high fidelity stereo loudspeaker.
This highly innovative hardware architecture requires a negligible amount
of additional space and removes the need for compromised internal speakers
or bulky traditional external systems.
In addition to improving the audio fidelity and user experience,
the audio systems reduce component cost,
size and weight while providing increased design freedom
The benefits of this audio systems become clear when you first experience high-quality audio coming directly from the video display.
This unified multimedia experience is delivered by a smaller package,
with less hardware to take up space, and no additional wires to add clutter.
Although flat panel displays have helped with the downsizing of monitors,
TVs and other consumer electronics,
the sound quality of speakers systems built into these smaller packages has suffered greatly.
This is not the case with embedded audio systems,
where big sound actually comes from a smaller package.
