1. We should consider the sound environment. Portable speakers are generally small in size. Its shell material is generally made of very malleable plastic or thin metal, so in order to have a better sound quality, we should try not to place it in direct sunlight. Don't put expensive things on it, as it will definitely be deformed, as you can imagine.
2. We should also pay attention to the ambient temperature of the card audio. Generally speaking, the environment temperature of the card audio should be between 18℃~45℃. If the temperature is too low, it will directly affect the performance of some components, such as the electronic tube machine. Sensitivity.
3. Turn on and turn off: For some split-type card speakers, we must follow the front-to-back rules when turning them on. In other words, we should turn on the main audio source such as the CD player before turning on the audio unit. Then when we shut down, we must first turn off the audio unit, and then turn off the main audio source. Some consumers will connect the amplifier during use, and we must turn off the amplifier first when shutting down. It is conceivable that the purpose of this is to fear that the current of the amplifier will impact the sound. Normally, you should turn the volume down to the minimum when you turn on the computer, and slowly turn it up according to your needs after you turn on the computer.
4. Is the line connection. Portable plug-in speakers, in order to make it easier for consumers to carry, parts can usually be separated, many people usually carelessly, do not turn off the power when disassembling, the machine is still powered on. Everyone should have a bit of common sense, and it is very dangerous to unplug active devices with power on. Even if we use passive devices such as microphones, we will turn off the power first, because the distances designed by the manufacturers when producing the plug-in audio terminals are generally very close, and the audio cables are usually tightly joined. Together, people usually short-circuit the speaker line when wiring. This will cause the sound quality of the audio to deteriorate and distortion, and more serious may directly cause your audio to be scrapped.
5. It is the volume adjustment: when listening to music with the card audio, you should not adjust the volume to the maximum as soon as the power is turned on. All parts of the machine just turned on are still in a preheating state. A louder volume will cause the components to work super-nuclearly, and it may not matter once or twice. If it is used for a long time, it will cause great damage to the components. So when we use it, we should listen to it at a low volume for a while, and then enjoy it.
