To enjoy music always and everywhere, you just have to choose and buy a portable speaker system. We will tell you about what portable speakers are, how they work and how much they cost.

How to choose the right portable speakers

If you do not think life without a laptop, MP3 player and run on PSP, then you definitely notice that the music on them is played badly. Do not hang your nose, help is already near. Connect portable speakers to the player, prefix and phone - and the world will be flooded with new sounds.

Of course, portable speakers are not yet created for picky connoisseurs; it is suitable only for those who want to listen to their favorite tunes, without paying attention to the disadvantages, or those who do not have the opportunity to deploy a large full audio system. You will not bring with you a cottage, a campsite or a picnic with shish kebabs, a home-beast machine that rows at low frequencies like a hundred of angry lions, and on the upper ones it breaks glass cups. But do not assume that the portable speakers are just another loudness, designed to pump money from purse lovers to relax in nature and supporters of a healthy lifestyle. The quality of playback, in comparison with stationary aggregates, leaves much to be desired, but not all inquiries like picky music lovers.

To choose and not to miss, to get started, determine why you have portable speakers. If you just boast of one time in front of nothing tumbling in the audio systems of friends - take that first hand to turn around, and do not be tormented: equally throw a device at the table and forget about its existence. If you still intend to use it for the full program, then find out for yourself whether you will connect flash drives and memory cards, and at the same time determine the type of power. For those who want to use portable speakers far from sockets, battery models will work with them: they do not need to worry about battery life. Again, the more powerful the system, the more difficult it is. To listen to music from an iPod in the office or home a cumbersome, powerful system will fit, but for a tourist with a backpack or athlete who runs from a heart attack, something much easier and more compact is needed.

It's worth remembering that the audio inputs for the speakers are also different. There are columns that are designed only for certain models of MP3 players or mobile phones, which have special connectors for quick connection of devices - until now. They are almost always unusual, non-standard and work only with devices declared by the manufacturer as compatible.

Key Features of Portable Speakers

Monophonic speakers of type 1.0, which connect via a 3.5 mm jack, gradually go away in the past. In their place stand stereoscopic, type 2.0 or 2.1 (with a subwoofer). But the "lonely" do not give up; Companies such as Sven and JBL continue to come up with new models for those who appreciate the small size and small weight of devices.

How to choose portable speakers. Number of bands of the AU

To make the sound less distorted, speakers may have several speakers, each of which is responsible for a specific frequency band. There are one-belt, two-belt and three-column speakers. It is easy to guess that single-bands consist of one universal speaker, two-belt - of two: high-frequency and low-frequency. In the three-band speakers, in addition to high-frequency and low-frequency, there is also a medium-frequency speaker.

Any band of AU can be brought into the divine kind, using equalizer-adjusted filters at the level of frequencies.

Each filter amplifies or diminishes the signal in a certain frequency range, adjusting the sound of music of different genres exactly for your taste.

Maximum reproducible frequency

In portable acoustics, the maximum sound frequency is in the range of 10,000 to 55,000 Hz. For accurate, practically natural reproduction it is necessary that the upper limit of frequencies be as high as possible. The wider the frequency band, the more natural the sound.

Subwoofer is a special channel for high quality bass reproduction. It requires a separate column.

The power of the subwoofer is measured in W RMS (Root Mean Square - RMS). RMS shows what power outputs the columns for a long time; usually it ranges from 1 to 150 watts.

Signal / Noise Amplifier Ratio

If you set the volume control to a maximum, not including music, then the speakers will be continuous noise. There is nothing terrible in this: any amplifier will make noise, and the whole question is how much it is. The higher the signal / noise value, the better your portable speaker will sound. Almost all models have a signal / noise ratio of between 45 and 100 dB.

Built-in "native" batteries are less weighed and have a large capacity. The sly manufacturers are sure to complete models with such batteries and chargers.

Typically, portable speakers require two or four batteries. But there are monsters, both willing and eight, and ten. The more batteries, the more difficult the device itself is, of course. But he is working more autonomously for a long time.
