With the fierce competition in the Bluetooth speaker market, various differentiated products also appear, and market refinement is an inevitable trend. According to the direction of non-application, there are three kinds of Bluetooth speakers: portable Bluetooth speakers, outdoor Bluetooth speakers and home Bluetooth speakers.
How to choose a high-quality Bluetooth speaker for such a huge speaker system? In fact, as long as you roughly choose from the following aspects, you can find a Bluetooth speaker that will satisfy you.
First, the sound quality.
Dual-channel speaker unit is superior to mono speaker in audio structure and physical cavity. Good sound quality requires high-quality speakers. Because of the structure of sound cavity, small single-tube speakers generally cannot show good sound quality.
Any speaker needs to listen to its sound effects in person when purchasing. If a speaker can achieve a strong sense of balance in all frequency bands, it will not be exhausted; The high frequency is beautiful and transparent, the middle frequency vocal expression is real and moist, and the low frequency is strong and powerful. Then nine times out of ten, she can interpret any music.
We can also use some data as reference. If the maximum decibel is less than 80, then such a sound effect is not suitable. The greater the signal-to-noise ratio, the stronger the anti-jamming ability and the better the fidelity effect. It is suggested that speakers with signal-to-noise ratio not less than 70dB should be generally selected.
Second, function
The speaker's placement of functions is not as good as possible. If it goes too far, it will usurp the role of the master and lose its original intention. Some functions may even become chicken ribs. For example, some speakers in the market shake the function of changing songs, and the songs are accidentally cut, which not only disappoints but also affects the mood. Some functions are more user-friendly, such as hands-free function, which can not only prevent radiation, but also facilitate answering calls.
Of course, the Bluetooth speaker depends on the Bluetooth version. At present, the common Bluetooth versions on the market are 2.0, 2. 1, 3.0 and 4.0, which are backward compatible. The transmission rate of Bluetooth 2.0 and 2. 1 versions can reach more than 2Mbps. The latest versions 3.0 and 4.0 greatly increase the transmission rate to more than 24Mbps, and the transmission distance can reach 60 meters. The higher the Bluetooth version, the faster the receiving rate, the farther the transmission distance, and the smaller the power consumption of the speaker, so the sound quality fidelity effect of the speaker will be better. So I suggest you buy a high-end version of the Bluetooth speaker. If the version is too low, it is easy to have intermittent music.
Some outdoor Bluetooth speakers have three-proof function, which is also a very good function. In fact, this function can also be applied anywhere. I believe everyone will like the sturdy and durable speakers. Therefore, it is recommended to refer to this item when purchasing.
Third, battery life.
Any electronic product is the same, and the longer the battery life, the better. Under normal use, the endurance of Bluetooth speakers should be at least 8 hours. Pay attention to the battery capacity here. Battery capacity = service time × equipment power ÷ battery voltage, so the larger the capacity, the longer the battery life. Take a two-channel speaker as an example, the power is concentrated between 4-8w ... If you want to achieve the ideal playing time, the battery capacity should be above 1500mAh.
Fourth, portability.
This is for portable Bluetooth speakers and outdoor speakers. The smaller the size, the easier it is to carry. Choosing a portable speaker depends on the adaptability of the speaker, and it needs to be portable in any case. At this point, the circle is stronger than the square.
Verb (abbreviation of verb) materials and materials
A good Bluetooth speaker must have exquisite materials and exquisite workmanship. Now there are many shoddy Bluetooth speakers on the market, which not only fail the quality inspection, but even cause harm to people. For example, many paints contain excessive lead, and these materials will unconsciously affect people's health. Therefore, you should read the quality inspection certificate clearly when purchasing. For the product technology, it is necessary to observe the details of the speaker, such as the regularity of the edge of the key, the fineness of the mold line, the feel of the material and so on. The exquisite workmanship of the products can be seen by careful observation.
The appearance of intransitive verbs
It's difficult to adjust, but I suggest you buy a round Bluetooth speaker, which will not only feel better, but also be safer and easier to carry. Of course, some people like individuality, others like gentleness, and they can buy according to their own preferences. The above suggestions are purely for reference.
