What is a subwoofer USB?
Subwoofer Universal Serial BUS is a peripheral device that can allow laptops and desktop computers to create low -frequency sounds. Some computer speaker systems use the audio connector of assemblies, although others use USB port. One type of USB subwoofer is built into a driven amplifier and has audio outputs for top-of-the-line (TRS) for external speakers. Another type of subwoofer USB is designed specifically for use with laptops. The software is usually used to separate high and medium tones from low tones, so the first can be sent to the built -in notebook speakers, while the second is reproduced by the peripheral USB.
The purpose of the subwoofer is to emit low-frequency sounds in the range of about 20-200 Hertz (Hz). The sounds that fall within this range are usually referred to as bass and the sound system that is unable to produce them may sound hollow or tin. Simple two channel desktop speakers and laptop computer speakers often lack goodBass reaction, so the Subwoofer USB can sometimes be used to improve sound reproduction.
There are two main types of USB subwoofers that can be useful in different situations. One type of USB subwoofer is built into a power amplifier unit, which usually also provides a connection for two or more other sound channels. These systems usually have two or more-circle rings or other audio connectors, each of which can be used to connect the speaker. Other systems have other connectors that can enable other input devices to be connected. These systems use the USB signal to control the subwoofer and regular speakers, so they can be used on desktop and laptops.
Another main type of subwoofer USB is designed specifically for use with laptops. Some of these portable computers have excellent built -in speakers while others lackany bass reaction. The software is used to separate low tones from the source of sound so that they can be sent to the subwoofer of the USB, while the rest of the sound is reproduced by built -in speakers. Because only low tones are directed to the peripheral subwoofer, the total sound quality is still somewhat dependent on the properties of built -in speakers. These subwoofer units are usually smaller and more portable than complete systems that include a driven amplifier and external right and left channel speakers.
