This thing costs $30 from Twin Towers Trading Inc. and apparently amplifies your phone's audio without actually being connected to it in any way. Anyone want to take a shot at how it does this?

using a hollow chamber for resonance.
not unlike an acoustic guitar

iPhone speaker is located on the bottom of the phone, pointed away from the device.

It uses battery power though. Maybe it just uses a microphone directly connected to amplified speakers. Like a megaphone.
>>53364633
I see now it is actually usb or battery powered.
probably NFC, near field pairing
It works by tricking retards into buying industrial waste for $30
>>53364713
Doesn't use any kind of pairing, it says.

>Iphone 5s or below
>NFC
Ayy lmao
>>53364697
BINGO, this anon get it, its juat a megaphone.
>>53364735
I think they mean bluetooth pairing. NFC pairs up just be being near each other. other boxes of similar design use nfc

With a microphone of course jesus christ.

there is no bluetooth pairing according to description

It is something they call near field audio.
Heineken had a promotion a while back in my country (Netherlands) offering these for free, in the form of a beer crate. Works pretty well actually
>>53364787
That is the on button. The microphone is probably under the phone, on the top of the slab.

What the fuck is this chinkphone?
>>53364805
Located on the complete wrong side of the phone to be picking up audio clearly?
>>53364802
this is the correct answer
>>53364802
It's because holland can into everything, literally
>>53364802
Bingo

>never heard of an audio pickup
lol
Is /g/ really this retarded?
I dont think it works with a regular mic+loudspeaker
I think Its more like a pressure zone mic or a magnetic resonance induction mic, because it doesn't amplify your voice if you speak near it, it recognizes the presence of a device even if its not playing sound
I've seen one of these, it works fine and doesn't need any connection, just put something with a speaker on it and the sound will be amplified
oh so the answer near field communication isn't correct
but near field audio is

I believe it uses what is referred to as "blue-tooth"
vibration
>>53364614
It's clearly powered by jet fuel and steel beams.

It's NFC but the website says no pairing at all, which makes it sound like no NFC. But this is clearly a knockoff of other NFC speakers. It is funny to see the /g/tards squabble over how it's obviously just an acoustic amplifier or bluetooth speaker.
I have been to parties where they didn't have a speaker, and the quick solution was a phone in a glass.
This is a cool extension of that.
I've got one of those in OP's picture yet black with my ISP's logo on the lower right corner. Fellow dutchfag as well.
It uses "Interaction" technology, which is fancy talk for a magnet strapped to the top surface that picks up sound from the speakers of your phone lying on top. I've opened up the device due to the micro-usb port being loose inside of it, hence why I got it for free. About 70% of the device is empty, the components there are the I/O board, the two speakers, the magnet sensor and the power-button board.
It adds slightly deeper tones at least.
its not nfc in a standard sense, although I think it falls under the nfc category because it is undoubtedly near field communication
There is an induction pickup in the box that senses em signals used by the phone speaker. I mimics the signal it detects from the phone speaker with its own driver.
It like a megaphone but it uses a magnetic pickup rather than an audio mic.
So I think it correctly states that there is no pairing. if you got two phone speakers close enough to the pickup it would probably try to play both of them.

It's a mic, amp and speaker in a thin plastic box

I own something similar to this and I'm pretty sure there's just a tiny microphone on the end which picks your phones sound, which is why it has to be oriented a certain way to work. Honestly they sound like complete garbage
>>53366946
I was close, it uses induction to pick up the signal a bit like a guitar pickup. Then there's just a mic on the inside which picks it up.
>>53365201

Yes, sounds like a shit party.

What a rip off.
Kmart has them for $10
>>53367302
also, I've opened one up and it has 2 coils on each side for sound input, like a microphone, wired up to a 2w+2w amp.

>near field audio
>"The NFA devices do the same but they are sensing the EM field created by your phone and using that as the signal to be amplified."
that's fucking baller.
