minus-squaresexy_peach@feddit.orglinkfedilinkEnglisharrow-up10·4 days agoI think it’s a noise in the ultrasound spectrum. Humans can’t hear it
minus-squareChronographs@lemmy.ziplinkfedilinkEnglisharrow-up12·4 days agoNa it made a click, that’s why we call remotes ‘clickers’
minus-squareLovableSidekick@lemmy.worldlinkfedilinkEnglisharrow-up12·edit-24 days agoThe 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.

minus-squareChronographs@lemmy.ziplinkfedilinkEnglisharrow-up8·edit-24 days agoLooks 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

minus-squarePavidus@lemmy.worldlinkfedilinkarrow-up4·4 days agoYou’re both right, the click actuated the ultrasonic noise, like hitting a xylophone.

minus-squareM68040 [they/them]@hexbear.netlinkfedilinkEnglisharrow-up1·4 days agoYup. Entirely passively powered - no batteries at all. Pretty ingenious stuff.
