Review on Outstanding Piezoelectric Ultrasonic Loudspeaker Waterproof by Ashwin Patel

September 21, 2022

Incorrect Specifications

Rated 30 Vp-p, Frequency Range 2.5 to 60 kHz. You can't drive these speakers at 30Vp-p at 60kHz because the "impedance" drops drastically after 12kHz. As a result, the current increases sharply, knocking out the drivers.

Pros

Quality Construction

Cons

Requires Socket
