On the Protection Circuit of Speaker switch
After the speaker circuit has been used for a long time, there does exist the phenomenon of drift, most of which are caused by the aging of electronic components (such as the leakage current of electrolytic capacitors increases, etc.), which is a normal phenomenon and has nothing to do with the volume potentiometer. When the speaker with a protective circuit is turned on, what you call a “tap” sound.-get someone to fix it! Because of the bad reasons, many people who specialize in repairs may also have worse sound quality than before repairs, so it is best to change professional speakers because professional power amplifiers are generally fully competent and work for a long time and continuously in a high-power state. Therefore, professional speakers are required to have a large margin of power and reliability.-what is the phenomenon that it cannot work properly? No sound? There’s no sound. Maybe the speaker tube is broken. –
Ask for English words about carton machinery and equipment, monochromatic slotting machine, two-color slotting machine, box binding machine, grinding and cutting machine, indentation machine, etc. How do you say these in English?
Monochromatic slotting machine: single color slotter/slotting machine
Two-color slotting machine: double color slotter/slotting machine
Nailing machine: carton stapler/stitcher
Die-cutting machine: die cutting machine/die-cutter
Indentation machine: creasing machine
How to set to turn on the speaker, turn off the speaker, headphones have sound.
Open the control panel-hardware and sound-Realtek HD Audio Manager-speakers-back panel.
If you tick before the “rear horn output”, the sound will be made. If the front panel “headset” is ticked in front of it, the headset will make a sound.
If you take two kinds of ticks, you will make a sound at the same time.
Some problems about the installation of chassis
The position refers to the installation position of the built-in drive inside the chassis, which is divided into two types: 3.5-inch drive position and 5.25-inch drive position. Among them, the 3.5inch space is mainly used to install floppy drives, hard drives and other drives, while the 5.25inch space is mainly used to install various optical disc drives, such as CD-ROM, DVD-ROM, CD-RW, COMBO and DVD burners.
Solid state drives are 2.5 inches. If you buy a chassis or solid state drives, you will send a 2.5-inch to 3.5-inch tray, which can be installed in a 3.5-inch position. 9.5mm and 7mm refer to the thickness of the hard disk. It doesn’t matter. They are all the same on desktops.
AMD’s latest APU and Speed Dragon, the flash dragon series CPU is the FM2 interface, the corresponding chipset is at the beginning of A, and the latest is the A88XJ FM2 + interface which is backward compatible with the FM2 interface.
The CPU of the latest FX series is AM3+ interface, and the corresponding chipset is 990FXMagi 990X.990FX.
This is the end of the introduction about turning off the box machine and the chassis switch. I don’t know if you have found the information you need. If you want to know more about this, remember to collect and follow this site.
