The pictures, it's noteworthy to say, make the device look like it has been built into the case of a small flashlight, not a remote control.
** The IR LED is likely stronger than usual and needs to be focused to work at long distance.
But are infra-red controlled speakers really common? I'd expect
bluetooth to be the protocol of choice and not easily duped by such a device. Or is this something else, and the news story has it garbled?
** IR is the only common method of remote control for audio gear.
Bluetooth is mainly used with cameras or smartphones.
FYI:
The news item makes no sense - even if you manage to trigger the "mute"
on a speaker the users will soon put it back in action.
The 'arms race' will continue...
IR is disappearing on consumer gear.
We're seeing a majority of LCD & OLED TVs
now come with an RF (Bluetooth) remote, not IR
So joe/jane doesn't have to point it anywhere
