What is a portable speaker and how does it transmit sound?

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

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

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

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

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

• Portability and autonomy. This audio device does not require a connection to an outlet to operate, as it runs on batteries or rechargeable batteries. There is also no need to connect to a smartphone, since the device is equipped with USB ports. You just need to install the flash drive and you can start listening to music;
• Small size. You can easily put the device in a bag or backpack and listen to music anywhere;
• Sound. Built-in speakers provide better sound quality than a smartphone. The volume of sound, its depth and quality is achieved thanks to the large speaker. The product reproduces mid and low frequencies especially well;
• Ability to connect to external devices using Bluetooth wireless network. The radius in which the device will operate is approximately 20 meters;

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

When purchasing a product, you need to pay attention to the presence of noise and signal level. The closer the signal value is to 100 dB, the higher quality the sound reproduced by the device will be.

Many models have a noise reduction 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 storage 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 their small size, the capacity 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 storage devices require much more power and space, so inexpensive products that are small in size do not have these connectors.
