Movie S2
Transparent loudspeaker playing music in front of the screen of a laptop.
Movie S3
Recording of the transparent loudspeaker playing a linear sine sweep from 20 Hz to 20 kHz within 20 s.
Movie S4
Side view recording of the transparent loudspeaker playing a logarithmic sine sweep from 20 Hz to 20 kHz within 100 s. Vibrations of the frame and out-of-plane standing wave patterns of the transparent membrane are visible in the low-frequency range.
