8 maintenance common sense of mini bluetooth speaker, understand and have a look!

Mini bluetooth speaker is a kind of micro speaker. Many friends also call it "USB speaker". It connects to a computer or USB jack with a USB interface. It is compact, portable, and fashionable.
The mini speaker can be connected to most audio output devices, such as MP3, MP4, MP5, mobile phones, computers, etc. (some devices may require an adapter interface). The appearance is simple and stylish, small and exquisite, with a wide range of varieties. The body’s lithium battery power supply can be carried with you carry. High power output is also suitable for outdoor use. The combined mini speaker is more suitable to be placed at home.

Scientific maintenance of audio equipment is the key to extending its life. Here are some basic common sense for daily maintenance:
1. The normal working temperature of audio equipment should be 18℃～45℃. Too low a temperature will reduce the sensitivity of some machines (such as electronic tube machines); too high a temperature will easily burn out the components or cause the components to age prematurely. Particular attention should be paid to cooling down and maintaining air circulation in summer;
2. Avoid direct sunlight on audio equipment, and avoid close to heat sources, such as heaters;

3. After the audio equipment is used up, the function keys should be reset. If the function key is not reset for a long time, the tension button spring is in a state of stress for a long time, which will easily cause malfunction;

4. Before turning on or off the audio power, turn the volume potentiometer of the power amplifier to the minimum. This is the most effective way to protect the power amplifier and speakers. At this time, the power amplification of the power amplifier is almost zero, and at least it will not cause harm to the speakers during misoperation;
5. Turn on from front to back when turning on, that is, turn on the CD player first, and then turn on the front and rear stages. Turn the volume potentiometer of the power amplifier to the minimum when turning on. When shutting down, turn off the power amplifier first, so that the amplification function of the power amplifier is completely turned off. At this time, when you turn off the front-end equipment, no matter how large the inrush current is generated, it will not affect the power amplifier and speakers. Turn the volume potentiometer of the power amplifier to the minimum when the surface is closed, and it can be connected to the CD player before turning it off or after turning it off;
6. The machine should be used frequently. It can prolong the life of the machine, such as some parts with motors (recording stand, laser player, laser video disc player, etc.). If it does not rotate for a long time, some parts will be deformed;
7. Power on regularly. When it is not used for a long time, especially in humid and high temperature seasons, it is best to power on for half an hour a day. In this way, the heat generated by the internal components of the machine can be used to drive away moisture, and prevent the internal coils, speaker voice coils, transformers, etc. from being damp and moldy;
8. Wipe the surface of the machine with a clean, damp, soft cotton cloth at regular intervals; when not in use, cover the machine with a dust cover or a drape to prevent dust from entering.
