Na it made a click, that’s why we call remotes ‘clickers’
The click was the release of a spring-loaded plunger that pushed air through an ultrasonic whistle. The whistle was what controlled the TV or stereo.
Weird I think I saw a YT video explaing it and this is the info I remembered
Looks like it’s a bit of both: while they did work by emitting an ultrasonic frequency, they also made an audible click. https://www.theverge.com/23810061/zenith-space-command-remote-control-button-of-the-month
I feel like there’s a technology connections video on the topic but I could be hallucinating
Yeah me too
You're both right, the click actuated the ultrasonic noise, like hitting a xylophone.
