What kind of column with a flash drive, as it is called and works

Gone are the days when music lovers walked around the streets, carrying huge tape recorders on their shoulders. Now there are many compact and lightweight audio devices that allow you to enjoy your favorite songs anywhere. For example, such a device is a column with a flash drive.

What is a column with a flash drive

A flash drive column is a portable audio device powered by batteries or rechargeable batteries. Thanks to this, it is very mobile, which allows you to take the device with you and listen to music anywhere.

What is a portable speaker and how does it transmit sound

A flash drive column is a compact audio device that, in its appearance, is very similar to a regular radio. Despite its small size, it is able to provide a fairly loud sound. Of course, her sound quality will be lower than that of stationary acoustics, but much higher than that of a smartphone. The sound itself depends on some parameters.

The most common are models of format 1.0. They operate in the frequency range from 50 to 20,000 Hz and have a power of 2.5 watts. Such devices cannot provide high-quality sound and rich bass.

There is also an option consisting of two columns that have a total power of 6 watts. The sound they emit will be significantly better than the 1.0 system.

Fans of juicy bass should pay attention to models equipped with a subwoofer. The power of such a system can reach 15 watts.

A column with a flash drive has a number of undeniable advantages. These include:

• Portability and autonomy. For the operation of this audio device does not require a connection to an outlet, as it works on batteries or rechargeable batteries. Also, a connection to a smartphone is not required, since the device is equipped with USB ports. You just need to install a USB flash drive and you can start listening to music;
• Small size. The device can easily be put in a bag or backpack and listen to music anywhere;
• Sound. Built-in speakers provide better sound quality than a smartphone. The sound volume, its depth and quality is achieved thanks to the dynamics of a large size. Particularly well, the product reproduces medium and low frequencies;
• Ability to connect to external devices using a Bluetooth wireless network. The radius in which the device will work is approximately 20 meters;
• Universality. The gadget can be a complete replacement for the headset. Even the most inexpensive devices have the function of receiving an incoming call. The call will be displayed on the speakerphone, so you do not need to get the phone;
• The product also has a Powerbank function. It allows the gadget to act as an external charger.
  

Depending on the manufacturer and model, the portable device may have a number of other additional functions.

When buying a product, you need to pay attention to the presence of noise and signal strength. The closer the signal value to 100 dB, the better the sound reproduced by the device will be.

Many models have a noise protection function. It allows you to listen to music files even if there are smartphones and other devices nearby that can receive the signal.

What flash drives are used in such models

The most common external media option is microSD. Almost all existing models are equipped with such ports. These memory cards are small in size and consume very little power. Therefore, they are used even in the most inexpensive devices. Despite the small size, the volume of such cards can be large, which allows you to store a sufficient number of audio files on them.

Speakers with built-in high-capacity batteries are equipped with USB sockets. USB media requires much more power and space, so inexpensive products that are small in size do not have these connectors.

The maximum amount of memory that a specific device model supports is indicated in the attached instructions!

A large number of portable audio devices are on the market. This allows you to easily choose the best option and enjoy your favorite music anywhere.
