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…
