Haha what do you mean, that's the main feature they are advertising here. I agree that the advent of portable high-output, low-power audio amplifiers is chiefly responsible for the downfall of human society so I, too, hate to see it.
It even comes with a "Personic Speaker". From the website: "Ai Pin’s speaker system uses a Head Related Transfer Function (HRTF) to create a personally optimized bubble of sound, at a fixed distance, regardless of how soft or loud."
Unless physics has changed, I think headphones are the only way to do this.
Directional speakers exist and are very effective actually. Whether this device is using one, I have no idea.
You can't create a "bubble" of sound unless that just a marketing term for quiet and facing only the user.
Well I don't know about a bubble of sound, but there are "sound lasers"
go about 2:14 into that video. also outside of this argument, that is really cool either way. thanks for sending!
When you hear made up phrases like "Personic Speaker" or "Dynamic Island", it's usually a technical problem so glaring they're trying to spin it as a benefit.
