Speakers for Computer

"Most computers allow you to hook up external speakers using the sound output jack."

Speakers are popular output devices used with computer systems. They receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most speakers for computer are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound. Speakers usually come in pairs, which allow them to produce stereo sound from two separate audio channels.



Computer Speakers Do Not Work There are many reasons for computer speaker stops working, even you bought best portable speakers 2012, you may have no ideas for it; let’s see what the reasons may cause it. Cause This issue could be caused by any of the below reasons.

Sound card does not work Speakers are not connected properly No power to the speakers Volume on speakers turned down Volume on sound card turned down Bad hardware

Getting Better All the Time Starting in the 1990s, vendors began to offer higher-quality computer speakers. Similar to home theater and stereo systems, many computer speaker systems include a pair of small speakers for the midrange and high (treble) frequencies and a large subwoofer for the low end (bass). The small speakers are placed in a left/right stereo orientation, while the subwoofer can be located anywhere on the floor because bass signals are unidirectional. See sound card and subwoofer. Speakers typically come in pairs, which allow them to produce stereo sound. This means the left and right speakers transmit audio on two completely separate channels. By using two speakers, music sounds much more natural since our ears are used to hearing sounds from the left and right at the same time. Surround systems may include four to seven speakers (plus a subwoofer), which creates an even more realistic experience.

Brief Introduction of Speakers for Computer

Mini Speaker, USB Speaker, Portable Speaker

Computer speakers, or multimedia speakers, are speakers external to a computer that disable the lower fidelity built-in speaker. They often have a low-power internal amplifier. The standard audio connection is a 3.5 mm (approximately 1/8 inch) stereo phone connector often color-coded lime green (following the PC 99 standard) for computer sound cards. A few use an RCA connector for input. There are also usb speakers for laptop which are powered from the 5 volts at 500 milliamps provided by the USB port, allowing about 2.5 watts of output power. Computer speakers range widely in quality and in price. The computer speakers typically packaged with computer systems are small, plastic, and have mediocre sound quality. Some computer speakers have equalization features such as bass and treble controls. The internal amplifiers require an external power source, usually an AC adapter. More sophisticated computer speakers can have a subwoofer unit, to enhance bass output, and these units usually include the power amplifiers both for the bass speaker, and the small satellite speakers. Some computer displays have rather basic speakers built-in. Laptops come with integrated speakers. Restricted space available in laptops means these speakers usually produce low-quality sound.

For some users, a lead connecting computer sound output to an existing stereo system is practical. This normally yields much better results than small low-cost computer speakers. Computer speakers can also serve as an economy amplifier for MP3 player use for those who wish to not use headphones, although some models of computer speakers have headphone jacks of their own.



Common Features of Computer Speaker

Features vary by manufacturer, but may include the following: An LED power indicator. A 3.5 mm headphone jack. Controls for volume, and sometimes bass and treble. A remote volume control.

Cost-Cutting Measures and Technical Compatibility

In order to cut the cost of speakers for computer (unless designed for premium sound performance), speakers designed for computers often lack an AM/FM tuner and other built-in sources of audio. However, the male 3.5 mm plug can be jury rigged with female 3.5 mm TRS phone connector to female stereo RCA adapters to work with stereo system components such as CD/DVD-Audio/SACD players (although computers have CD-ROM drives of their own with audio CD support), audio cassette players, turntables, etc. Despite being designed for computers, computer speakers are electrically compatible with the aforementioned stereo components. There are even models of computer speakers that have stereo RCA in jacks.
