I don't know how the heck these things are supposed to be used. Wondered if anyone on the DCF might be able to throw some light on the puzzle.
A Korean neighbour gave me these speakers just before he left to go back to Korea, and I didn't get a chance to ask him about them.
The label on the back of each speaker says:
2.0Ch USB digital speaker
- and indicates the name of the manufacturer in China.
The back of each speaker has the words "Designed by SAMSUNG"
They are 2 desktop speakers - small, sort of oblong boxes - with a front face that is approx. 3" square and a sloped base that angles them up at about 45°.
Solidly made of black plastic, with no visible screws to open them, they have neoprene rubber on the base (presumably to minimise vibration).
There is a single USB plug that feeds into the back of the RIGHT speaker via a thickish cable, and a thinner cable comes out the back of the RIGHT speaker and goes into the back of the LEFT speaker.
The RIGHT speaker has 3 nearly flush-fitting (only slightly raised) buttons down one side, each one above the other, and a mini-audio socket below the 3rd with "AUX
" written by it.
The three buttons, from the top are marked nearby:* EQ/MUTE
* VOL +
* VOL -
When you plug the USB into the laptop, a little blue light comes on behind the grill on the speaker face of the RIGHT speaker - nothing on the LEFT speaker.
When you play some music and plug the USB into the laptop, nothing in Win7-64 sees it as a new device, and nothing seems to happen - no noise comes out the speakers, despite fiddling with the buttons.
The AUX port doesn't seem to be an audio IN port (I tried that), so is probably (?) an AUX audio OUT.
Leaving the USB plugged in causes the RIGHT speaker to get a bit warm on one side, so I presume that is an amplifier circuit heating up.
I did a search on the net hoping to find a spec and a handbook and drivers, but the only references I could seem to find were in a few Spanish-language sites that sometimes indicated that the speakers were "discontinued". If any site had a photo of the speakers (most didn't), they always showed the RIGHT speaker with a singe very prominent button - so it was a slightly different model to the ones I have.
The speakers seem not to have been used - they still have their adhesive protective plastic covering on (which I peeled back to get the buttons clear and access the AUX socket). So maybe the Korean guy hadn't used them. I think he had an Apple phone, and I supposed he had got the speakers for that, but I'm not sure.
Anyone got any ideas on this?
