So if the remote still works then wouldn’t that mean there is still a microphone? Or have they gone back to line of sight infrared? Or am I just thinking of the really really old remote tech?
Not fully related, but early TV remotes used sound rather than IR. The buttons made a distinctive “click” noise, from a mechanical mechanism. The different clicks were detected in the TV and used as input.
Plus side, no batteries to deal with.
Down side, about as (un)reliable as you would expect.
Cool, thanks! No problem. I understand it was analog electronics and using an ultrasonic signal makes sense, but what I wondered about was how did the receiving end (the TV) differentiate between the signals for the different buttons and then decide to execute different procedures based on that. Still pretty interesting in any case.
This should be a web site or YT channel. How to remove such bits without bricking the item.
To be fair, OP didn’t claim that the remote wasn’t bricked…
It works! I was fully prepared for it to not work and explain to my wife why we need to order a new one, but no issue at all lmao

…when have remote signals ever used microphones?

That’s wild. How did the TVs identify the distinctive sound? That seems like it would be a pretty interesting engineering trick.
I believe it was old school analogue electronics, but I’m speculating there.
I just looked it up, it was ultrasonic signals. The main one was the Zenith Space Command.
