Portable speakers with radio and USB flash drive: description, characteristics

One of the main criteria for choosing an amateur system at an amateur level is still the size. Massive speakers will certainly fill a large room with sound, withstanding frequency-amplitude transitions across the entire spectrum. However, such equipment can not be taken with you for a walk, a trip or a summer residence. The concept of mobile analogs of music systems has existed for several years, but recently this segment has gained unprecedented popularity.

At the same time, users are looking for not just a column, but models with a wide functional content. A fairly common option today is a portable acoustics with a radio and a USB flash drive, supplemented by a decent power. Similar systems are present in the lines of many manufacturers, but first it is worth considering the features and operational capabilities of portable devices.

Features of portable acoustics

Musical equipment of this type is created with an emphasis on two distinctive differences. First of all, this is the possibility of autonomous work. Such models are calculated not just for use in another room, but for listening to music without connecting to an outlet. Accordingly, portable speakers with a radio and USB flash drive works either from batteries or from batteries. The presence of USB will be beneficial not only the ability to connect the USB flash drive, but also power from the computer. Also there are devices that combine both ways of power supply.

The second characteristic difference is due to the fact that mobile systems have small dimensions in comparison with stationary columns. Of course, this also affects the sound quality. There is no question of transferring the possibilities of classical acoustics beyond the home. However, against the background of conventional headphones and compact MP3 players, portable speakers are prominently displayed for the better. As for the other parameters and characteristics, they differ little from traditional models.

Main characteristics

The spectrum of reproduced frequencies will in many respects determine the basic capabilities of acoustics. The upper limit can vary from 10 to 55 kHz. Accurate and as close to natural sound processing of the signal requires that this figure be as high as possible. The quality of playback on this site also depends on the number of bands - the best choice is to have three speakers. The lower frequency level is responsible for the bass.

In the case of portable models, the speakers can reproduce between 20 and 500 Hz. Than this indicator is lower, the more rich the sound will be. Among the paramount characteristics of any music system is the power. Already in the basic configuration, portable speakers with a radio and USB flash drive can contain a subwoofer - this channel and the reproduction of bass. To determine the power, you should take into account the RMS, that is, the rms value. The range varies from 1 to 150 watts.

Specialists pay attention to the ratio of signal and noise. If you turn the volume setting to maximum, but without sound, you can hear a noise background. It should increase as the signal strength increases. This value varies from 50 to 100 dB, and the more it is, the better the sound.

Radio and USB flash drive support

In this case, the presence of a radio tuner and the support of a flash drive are mandatory, although not all manufacturers supply acoustics with such functionality. It should be noted that the radio in mobile systems is limited only by the work in the FM-band. If a wider playback format is required, then you should consider the possibility of synchronizing the equipment with another device that supports the required range.

Now you need to go to other devices with which this kind of speaker system can work. So, portable speakers with a USB flash drive provide the ability to play files directly from a removable drive. Actually, this capability turns equipment into almost a musical center. In addition to the flash drive, a hard disk can be connected to the system, and in some models there is also a slot for the SD memory card.

Additional Functionality

To communicate with other devices, Bluetooth is usually used. The module is easy to manage and convenient, if you need to connect the device without the use of wires. The only thing to consider when buying models with this technology is the number of supported labels. This number determines how many devices can be associated with acoustics and quickly switch from one to another during operation. To facilitate synchronization, acoustics with Bluetooth are also equipped with NFC-type modules, through which the pairing is realized by placing the device on a special label.

Similar functions are performed by the Wi-Fi channel, along with this, opening and access to the Internet. With this option, the user can directly broadcast music from the smartphone through the speaker system. Or you can set up a radio broadcast using a web service. Especially for fans of Apple gadgets, some manufacturers offer the technology AirPlay, which increases the convenience of organizing the interaction of two devices.

What else to consider when choosing?

It would seem that the usual parameters of choice during the operation can present surprises. For example, many do not correlate the weight of the columns with the character of further exploitation. If you need a model for use in the office or at the cottage, then do not discount on the mass - the large speakers will provide a better sound. If you plan to use the system in nature or during walks, then Sven compact speakers with small dimensions and weight will do. For comfortable listening it is necessary to provide in advance and protection from noise, which is supplied with modern models - such an addition will not spoil the impression of listening to your favorite tracks, even if nearby work cell phones and other signal receivers.

It is not superfluous to envisage the possibility of passive work - that is, without its own power source. Already noted the possibility of charging from the USB interface when connected to a computer. In addition, portable speakers with a USB flash drive are able to perform their function when connected to mobile devices.

Model from Sven

Producer Sven realized the idea of a compact and easy-to-use physical acoustics in the Boogie Ball model. In shape, the system resembles a flattened multi-colored ball, which is small in size and lightweight - by the way, its mass is 600 g. The spectrum of reproduced frequencies varies from 100 to 20 000 Hz, and the power of single-band equipment is 2.4 W. In terms of functionality, Sven acoustics is endowed with almost all the features typical of the modern model. But there is another advantage in this version of the mobile speaker - it's a price tag. The manufacturer realizes this acoustics for only 400 rubles. Obviously, you can not find a high-quality system for such a price, so you should prepare for work with a flimsy cable and a weak plastic case. In the rest, the device represents the optimal entry-level solution with USB support for the USB flash drive.

Offer from Supra

A more serious version is offered by Supra company in the performance of Pas-6255. Although outwardly a single-band device resembles car acoustics, it can also be used as a universal system. The list of options contains: USB with the ability to connect a flash drive, FM tuner, a slot for CD-cards, as well as an alarm clock and a voice recorder. With regard to performance parameters, the model is a 5W stereo system with battery, battery or the same USB interface.

It is also possible to work with headphones through the standard mini-jack Supra. Acoustics in this version is estimated at 1200 rubles. On the aggregate of data, this is not bad, but it is also necessary to prepare for a number of shortcomings. For example, there is a sun-blown display and uncomfortable navigation through the menu. Compensates for these flaws worthy of sound, in particular, you can hear bright and clear bass.

Model from JBL

Once the company offered very decent portable acoustics Charge. With a balanced functionality and tolerable sound, the model was inexpensive, which ensured its success in the market. Today, the portable acoustics of JBL are represented by the Pulse version, which continues the concept of Charge. The peculiarities of this system include dynamic illumination, in which many colors are involved. There are plenty of such options on the market, however, Pulse feels responsible approach to the implementation of the backlighting modes, and to the characteristics of the light supply itself, which does not tire the eye.

To the pluses of the device users also refer to the overall quality of production, optimal sound settings and 5-hour battery life. Unfortunately, the portable acoustics of JBL in the Pulse series does not apply to cheap offers. Its price tag is 8,000 rubles, but models with original design and exceptionally competent illuminations are always in demand.

Speakers from Sony

The brand Sony offers portable speakers in the modification of SRS-X5, which have an impressive arsenal of features. The device weighs more than a kilogram, but at the same time it is compact in size. At once it is necessary to note the qualitative materials from which this portable acoustics is made. The reviews point out that the attractive appearance of the system and the marquess of the enclosure surfaces make it necessary to handle the equipment with care. Inside there are 3 speakers with a total power of 20 watts. Actually, the high-quality sound is the main advantage of this system, not counting the possibilities of connecting to a computer, playing audio-CDs and radio, and also synchronizing with mobile devices.

Acoustics from Yamaha

The Japanese manufacturer has considerable experience in the development of music projectors, so the speakers with a USB flash drive in the performance of NX-P100 have successfully balanced characteristics. The model has a compact multi-colored body weighing 1.5 kg, which contains two broadband speakers. Acoustics provides the ability to use the USB interface for a variety of purposes, has wireless modules and NFC technology.

It should be noted that this is one of the few options that, in addition to functional and sound qualities, offers good protection against external influences. This is a column with a flash drive, which have insulation from the water from different sides, that is, you can safely use the acoustics on the beach.

Version from Philips

Philips is also known for portable devices, including the base model P9. On its platform, more recently, the continuation of the line in the form of acoustics Fidelio P9X. In comparison with the previous version, the novelty got rid of the stand, which made the case laconic and generally more attractive. In terms of sound quality, the model should be regarded as one of the best in the class. The fact is that this is not just a portable acoustics with a radio and a USB flash drive, but a music system with two broadband speakers and a pair of tweeters. Of course, there is a downside to this configuration - size and weight. This representative of the Fidelio line can not be taken with you for an easy walk, although outdoor recreation can be optimally suited for using this model.

Conclusion

As you can see, the segment of mobile speakers is quite diverse. Almost all modern models support work with USB-interface, have FM-receivers and a lot of other useful additions. But the best portable acoustics also combines optimal sound performance and practicality in operation. The presence of powerful multi-loudspeakers will provide a decent background music, and reliable and resistant to damage finishing materials will protect the technical stuffing from external influences. Unfortunately, these and other small things are not always realized by manufacturers in the same model, but a certain balance can still be found.
