Mini audio is a kind of miniature audio, many brothers also called it "usb audio", usb interface to connect the computer or usb plug mini speaker hole, delicate, convenient to carry, novel style. Mini audio can connect to most audio output devices, such as mp3, mp4, mp5, mobile phone, computer, etc. (some devices may need a transfer interface).

Originally, the primary role of mini audio is to improve the auditory environment of a single room, whether it is resting or doing housework can create a good atmosphere. Many men like to get up in the morning to listen to the news, women like to make up while enjoying music. Because of its simple construction, the mini stereo doesn't have too many wires in addition to the power supply, so it can be moved around without interfering with the decoration of the home.

Desktop audio selection method

This kind of small audio generally can be divided into two categories.

(1) Active speaker class.

Advantages: simple, two boxes, power amplification components are inside the box, power switch and volume size knob installed on the surface of the box, low price.

Disadvantages: Relatively speaking, the sound quality is poor. Reason: the sound box is vibration sound, and the audio power amplification component is afraid of vibration and expect quiet, it is a pair of opposable. Two boxes are not very symmetrical (one has amplifier circuit), listen to music expect stereo sound.

(2) Split combination sound.

Advantages: the same grade and active speakers than, better sound quality. Features are two boxes and an amplifier, electrical safety is good.

Disadvantages: High quotation. Reason: The power amplifier component is put into the metal shell alone, which increases the cost.

At present many mini combination stereo with cd player and radio function, the price is higher.

Usually the lowest performance frequency of sound system can be selected above 40hz, of course, this is for each speaker box only one unit. If each speaker can guarantee two units, then the sound effect will be much better.

Sound layout and maintenance strategy

Generally speaking, we advocate that you place the two speakers of the small desktop stereo closest to the listening position, in a certain axis of symmetry in the room. The distance between the two speakers should not be too far away. Otherwise, it is difficult to generate a sound field in a balanced way with the power of the two speakers of the desktop sound system.

increases, also avoid the left and right sound field imbalance caused by the different reflection paths of two vocal channels.

Mobile phone to stay away from the maintenance of the speaker circuit, although your desktop audio can be arbitrarily placed, but 10 million and mobile phone, cordless phone, TV, refrigerator, microwave oven and other items to keep distance, from the computer case is also far away from the best. Different electrical "right and wrong" placement, can best keep each electrical circuit will not cause damage because of interference.

Source is very important No matter how good the sound system is, no good music is useless. Because desktop audio is generally used in bedrooms and kitchens and other small space to create a music background, so we advocate the use of desktop audio consumers can try to use more durable classical music, light music or listen to FM radio, play high quality and large capacity md is also good.
