When traveling, I dread listening to music or playing a movie on my netbook, unless I have earbuds/headphones plugged into it.

#3 has a speaker for laptops/netbooks that plugs into a USB port which is available now.


Quite a nice accessory for the road warrior or anyone that travels frequently with a laptop.


Seems they invented the perpetuum mobile :rolleyes:

Any questions? :bigsmile:



Would hardly be an AMPLIFIER if it didn’t AMPLIFY would it?

From chambers online dictionary:

“amplifier noun 1 an electronic device that amplifies the strength of an electrical or radio signal without appreciably altering its characteristics, used in audio equipment, radio and television sets, etc. 2 photog a lens that enlarges the field of vision”.

perpetual adj 1 everlasting; eternal; continuous; permanent • in perpetual bliss. 2 continual; continually recurring • perpetual quarrels. 3 blooming continuously. perpetually adverb.
ETYMOLOGY: 14c: from Latin perpetualis, from perpetuus uninterrupted.

The law of energy conservation still applies.

From chambers online dictionary:
A dictionary is not useful to explain the physics of an amplifier.
