Mini speakers can play wonderful music only by connecting laptops, mobile phones and other devices when there is no power supply. Some speakers are equipped with large-capacity lithium batteries, and the products can play music for 3-5 hours. So, the following is my basic understanding of mini speakers. Welcome to read and browse.
What is a mini speaker?
A mini speaker is a kind of mini stereo, which is also called by many friends? USB stereo? Connect a computer or USB jack with USB interface, which is compact, portable and fashionable. Mini speakers can be connected to most audio output devices, such as MP3, MP4, MP5, mobile phones, computers and so on. (Some devices may require an adapter). The shape design is simple and fashionable, small and exquisite, and there are many varieties. The lithium battery of the fuselage is powered and can be carried around. High power output is also suitable for outdoor use. The assembled mini speaker is more suitable for home.

Especially sports speakers, bicycle stereos, etc!
Common terms in mini-speakers
What are the terms commonly used by audiophiles? The terms commonly used by enthusiasts are abstract, and the commonly used terms are as follows:
1, nerve line: mainly refers to the signal line that transmits low level (millivolt, microvolt level) and small current. Generally used for audio and video, it is the meridian of God. The plugs at both ends of the advanced nerve wire are gold-plated RCA plugs, and the surface of the wire is coated with anti-static protective layer.
2. Heating wire: mainly refers to the speaker signal transmission line with large cross section and multiple strands. High-quality heating wire is made of oxygen-free copper and other materials.
3. Broken machine: The so-called broken machine is similar to the running-in period of mechanical machines, that is, after the audio equipment works for a certain period of time, the temperature inside the machine is the same as the ambient temperature, so that the working state of power amplifiers at all levels reaches the best point, and the reproduced sound is the best at this time.
4. Motorcycle: The so-called motorcycle comes from English Modify, which means to modify and decorate. Enthusiasts replace, transform and upgrade the components or circuits in the audio system, which is called motorcycle.
5. sonic boom: The so-called sonic boom refers to the deafening atmosphere produced when the music enters the climax when the audio equipment is replayed.
6. Gallbladder machine: Gallbladder machine refers to an amplifier made of electron tubes. The warm and transparent sound quality of electron tube power amplifier makes the older generation of enthusiasts unforgettable.
7. Stone machine: The so-called stone machine refers to an amplifier made of transistors.
8. Gallstone machine: that is, audio equipment made by mixing electronic tubes and transistors. Usually, electron tubes are used as preamplifiers and transistors are used as post-amplifiers.
9. Ring cow: The so-called ring cow refers to the ring transformer, which has smaller magnetic leakage than the ordinary transformer.
10, big pond: the big pond refers to the power filter capacitor, generally 10000? Large capacity capacitance above f.
1 1, beautiful sound: the sound quality of audio equipment is very good, which meets the requirements of high fidelity.
12, resolution: refers to the reproduction of audio equipment with certain transparency, giving people the feeling of "crystal clear".
13. Dyeing: The so-called dyeing refers to the sound that is not in the playback sound due to the vibration of other objects or materials caused by the vibration of sound waves. It is harmful to the playback effect.
14, microphone: refers to various microphones.
15, tonic: refers to the high-quality components used in the reconstruction of the sound system.
How to buy mini speakers?
First, whether there is a good listening environment.
As a household appliance with the biggest individual difference, audio needs to be carefully listened and compared, and what kind of sound quality characteristics you like should be considered. And some audio companies only provide a place to show, but they don't give you room to listen, which is no different from selling department stores. Can't a dedicated audition room work? Beautify? Sound quality, it just provides a neutral and undisturbed space for you to carefully compare the characteristics of the system, and its smooth acoustic characteristics can fully reflect the advantages and disadvantages of audio equipment. In addition, a well-designed audition room often reflects whether the business knows acoustic knowledge, the taste and strength of the business. Therefore, in order to let you buy satisfactory audio, it is best to choose a business with an audition room when buying.
Second, whether the seller is knowledgeable.
If the merchant is obsessed with your questions about product performance and use, or tell you? Just right? But you don't know where it is. You should be careful. Because if the merchants don't understand it, of course, they can't recommend good products to you, and even wonder if the products they buy are genuine. The staple food can be sold whatever it wants, and the sound system must be run by knowledgeable people. Qualified audio dealers not only know the products they sell, but also know the characteristics of other goods on the market, and can objectively introduce the characteristics of different audio equipment to you. Can I give you a comparison space based on your full reference, instead of just asking? How much do you want? That's for money, not for your needs.
Third, it is not enough to have genuine copies.
Buying a stereo is different from buying other things. If it's true, it doesn't necessarily sound good. This stereo has its own personality. If they don't match well, they are like a couple. Personality incompatibility? It'll be weird. For example, the sound range of most power amplifiers in Japan is cold and hard, with a strong digital flavor. Only suitable for speakers with softer and warmer timbre. Will it be the same if you use products within 10 thousand yuan? Cold? Speak German and be recognized? Work hard? With JBL, the sound will be unbearable or ugly, so no matter how much you spend, the effect will not be good. However, many businesses, including some agents of brand-name equipment, ignore this factor and often engage in activities to promote their products? Not gregarious? This is very irresponsible. In addition to requiring businesses to be self-disciplined, consumers should also learn collocation knowledge to avoid blindly listening to advertising recommendations. In addition, the same price, due to different brands, its music quality is also different, and it often happens that the products purchased at high prices are not as good as those purchased at low prices. Therefore, understanding the knowledge of listening is a necessary condition for purchasing audio.
Fourth, whether to install and debug at home.
For many people who don't understand sound, when they get home, they are often at a loss about wiring as complicated as equipment, and they don't know how to set up and debug the system at all. So some people have to buy a set of machines at will. In fact, some businesses that really pay attention to reputation provide free door-to-door service. It is undoubtedly very important for merchants to install and debug for customers. They can often give you some suggestions to improve the sound quality according to the acoustic characteristics of your room.
5. Have you considered the need for upgrading?
Many people blindly follow the trend to buy stereos, and soon find that they are out of date and not easy to use. However, because they didn't consider the possibility of upgrading at first, they are now faced with the dilemma of continuing to use them unsatisfied or throwing them all away. At this time, you will find that waste is more expensive than using advanced equipment. Some consumers followed suit and bought a home theater last year, but later found that the sound quality was not good. This year, they gave up their equipment and bought hi-fi again, and more consumers even found that they had made a mistake? Will it? If you go on, you will lose the chance to get along with wonderful music. In the case of limited budget, it is not easy to buy a good sound system, and how to match it reasonably is more important.
How to use the mini speaker?
Because of the mini speakers? Boss? Small and easy to operate, experts point out that mastering the correct use method can not only make the product? Longevity , but also to improve the sound quality and increase their own music enjoyment is also of great benefit.
The first is the use environment. Mini speakers are small in shape, and the shell material is generally plastic or thin metal with strong plasticity. Try not to put them in direct sunlight, and do not put heavy objects on the top of the audio to avoid deformation of the shell. In addition, we should also pay attention to the ambient temperature in the mini speaker. The normal ambient temperature of general audio equipment should be 18℃ ~ 45℃. Too low a temperature will reduce some components? Like an electron tube machine? Sensitivity. If you are in the north, keep the mini speakers away from heat sources such as heaters and heaters. Too high ambient temperature can easily lead to premature aging and failure of components.
Followed by startup and shutdown. Some split mini speakers should follow the rules from front to back when starting, that is, turn on the main audio source such as CD player first, and then turn on the audio unit; Please turn off the audio unit before turning off the main audio source; If the mini-speaker is connected with a simple power amplifier, the power amplifier should be turned off first when it is turned off, so as to prevent the power amplifier from generating excessive surge current and damaging the sound. Turn the volume switch of the power amplifier to the minimum when turning it on, so as not to damage the speaker due to the instantaneous loud volume.
The third is the line connection. For portability, all parts of the mini speaker can be disassembled. For convenience, many people do not turn off the power supply when disassembling, so that the sound system is in working condition. As we all know, it is very dangerous to plug and unplug active equipment with electricity. Even passive devices such as microphones are not encouraged to plug in and out with electricity, because the terminals of the speakers are generally very close and the wires of the speakers are closely parallel. When wiring, the speaker wires are often accidentally short-circuited, which will lead to timbre distortion and even lead to the scrapping of speaker equipment.
The fourth is volume adjustment. When listening to music with mini speakers, it is necessary to avoid turning the volume to the maximum when it is turned on. Because the components of audio did not go through the preheating stage at first, the high volume will make them work at full load instantly, which will lead to the damage of components and make some internal fragile audio components fail for a long time. Every time you use the mini speaker, it is best to preheat it with soft music for more than ten minutes, and the volume is moderate. It is not too late to make full use of it after the machine parts are fully adapted.
