Achelous - a USound MEMS speaker for crisp and clear sound reproduction

How high is the power consumption of USound MEMS speakers?

June 4, 2018

First, we should clarify how power consumption is typically measured with electro-dynamic speakers or BAs. Since the impedance of these speakers is roughly constant over frequency (typically 4, 8 or 32Ω), this impedance value is taken as “nominal”. With this, a very simple transformation from a result obtained with a constant voltage into a result with…

Ganymede speakers measure only 4.7 x 6.7 x 1.6 mm.

What are the inherent advantages of USound MEMS speakers?

June 4, 2018

If comparing the USound MEMS speakers to conventional and Balanced Armature speakers a few inherent advantages present themselves: Smaller size; especially the flatness of USound MEMS speakers is unbeatable Practically no heat generation (especially compared to the electrodynamic speakers) Much lower mass; overall less mass and lower moving mass -> lower vibrations No electromagnetic radiation To…
