Speaker's Daily maintenance knowledge

1. In the boot, shutdown, restart and other operations, the speaker should be turned down to the minimum or the power off to prevent large current on the speakers caused damage.

2. Correctly set the sound card output mode. Generally we all use integrated AC97 sound cards, chassis back panel has 3 interfaces, we commonly use active speakers, so should be inserted line output interface (green), while the red interface is the microphone, the other is the line input (analog input) interface (blue).

3. Pay attention to the display of speakers. The right way to do this is to focus on the display, symmetrical placement, and to ensure that speakers are on the user, subwoofer direction is not strong, the position can be flexible; for the speakers that often use large volume, do not put the speaker directly on the computer table (especially the subwoofer), so as to avoid the resonance caused by the computer table distortion, At the same time, large vibration of high-speed working hard disk, optical drive is also harmful.

4. Do not make the speaker for a long time large volume of work, on the one hand, poor hearing, and also easy to burn the power supply and amplification circuit.

U disk (mp3), Mobile hard drive

With the sharp drop in the price of U disk (mp3), more and more people have them in the student group, which can be said to have replaced the floppy drive (floppy) as the new Removable Storage. Its advantages: small size, large capacity, stable work, easy to keep. and u disk (MP3) The seismic resistance is good, the deficiency is incorrect use method and static electricity easily damage it, especially attention is to exit the U disk program and then pull.

Mobile hard disk is a more capacity removable storage, the internal use of micro-hard disk, for students, the current market price is still high (relative to the hard drive price), the size of the mobile hard disk is smaller (but still larger than the U disk), and it's more seismic than the hard disk, but do not think it is not broken, Especially when it's working, it's best not to move it.
