In the last couple of years the popularity of the analog audio started to increase once again and this can clearly be seen by the number of vinyl record sales. There are many classical albums which are being reproduced and then sold as new, and they prove to be very successful. Most of the people agree that the digital audio media has more benefits than the analog audio media, but the same people agree that the analog audio has a more rich and natural tone. In what follows I am going to present you some information about each of these two types of sounds, as my article is focused on analog vs. digital audio.

The analog sound is a concussion pulsation of physical matter. The human ear is able to perceive this sound only when its frequency is between 1 hertz and 20k hertz which is 20,000 hertz. Thomas Edison, the famous American inventor was the first one to invent a device which is able to record the sound. What is fascinating about this is the fact that he was nearly deaf when he invented the first phonograph, the device which set the start for the recorded analog sound.

The phonograph worked this way: the lead cylinder rotated while the speaker talked in the cone, which could also be doubled as a speaker. Of course in time the technology evolved, things got better and better, the sound was clearer, and the recordings could be made for longer and longer periods of time.

The main characteristics of the analog machines is the fact that they record sound as wave forms, which is the natural form, just like the sound is present in the nature. On the other hand the digital machines take the samples of the signal and store them as pieces of data. The digital machines are able to provide higher signal-to-noise ratio, the noise being represented by the background sounds. This is the reason why you can hear background sound when listening to an audio cassette and you can’t hear it while listening to a CD.

The quality of the analog sound will deteriorate when it is copied and this is why in most of the cases the original cassette will sound better than the recorded one. This does not happen in the case of the digital data because it is just like you would copy bits of data from one computer to another. The recordings of the digital sounds are easier to perform as well because you can cut pieces out or select certain parts of the music, and so on. Some say that the analog sound is better because it doesn't simulate an "S" wave, but it captures it. This was my info on analog vs. digital audio.

Lenovo is a big Chinese multinational company that is producing all sorts of electronic devices such as: computers, notebooks, servers, netbooks, peripherals, printers, TV-s, scanners, storage devices and others.  It has the headquarters in Beijing China, but since it is a multinational company it has other subsidiaries all over the world. The company was founded in 1984 and since then it continued to develop more and more.

Lenovo is the largest seller of  PC-s in China, and the fourth largest producer of computers in the world. In 2009 it had a great revenue of 14.901 billion dollars.

Besides all the products we mentioned before, Lenovo is also producing some computer speakers, and this is what we are going to discuss about today. We’ll first discuss about the Lenovo ThinkVision USB Soundbar PC multimedia speakers. It is quite a cool looking sound bar that has 2 speakers in each end, each one with 1 watt RMS of power. So you might wonder why it looks like this, and not like a normal set of stereo speakers.

Well, the answer is because this is a special soundbar made to be attached on your monitor. So this means that it will stay there and it won’t take any space at all on your desk. Even though the power is not so big, so it won’t offer a very powerful audio experience, this device is a great alternative for the classic small stereo speakers. You will get pretty much the same power and sound quality, only that you won’t have any speakers on your desk.

Another advantage is that it has just a single cable. Most of the stereo speakers have two wires, one which is for the audio signal and connects with the computer and the other that is for power and connects to an AC adapter. But this speaker has just one, which is both for audio and power and which connects into the USB port. So we can place this soundbar into the “USB portable speakers” category.

So if you want you can take it with you when traveling and connect it to your laptop. It has quite an accessible price of 32 dollars but in some places you can find it even cheaper, so that’s why it is always best to search for the best deal before buying something.

Now let’s discuss about another speaker produced by Lenovo, and we’ll choose the M 220 mini speakers. As the name says, these are really small speakers. They are also from the USB category  of speakers, so it means that they are highly portable, and can be used anywhere with your laptop or computer. There is not much to say about these speakers, except that they have a price varying from 15-30 dollars, a small and pretty cool design and an acceptable sound quality, specific to most of the small stereo speakers.

There are probably some others speakers produced by Lenovo, but if you are looking for a really good audio experience we don’t recommend buying some speakers from this company, because speakers are not its strong area. What you can do is buy some speakers from a professional audio producer (such as Harman Kardon, Altec Lansing, JBL, Bose, Boston Acoustics etc.) and combine these speakers with Lenovo computers or notebooks.
