1. To distinguish the sound quality of speakers
1. The pitch of the sound, that is, the intensity and amplitude of the audio; 2. The pitch of the sound, that is the frequency of the audio or the number of changes per second; 3. The timbre of the sound, that is, the overtone or harmonic components of the audio. To judge the sound quality of an audio product, it is mainly to measure whether the above three aspects of the sound have reached a certain level. To be more popular, it is "three wrongs and three pairs." 1. A sharp voice is wrong; 2. A shrinking voice is wrong; 3. As long as the sound is deadly, it is wrong; 4. As long as the sound is sweet, it is right; 5. As long as the sound is full, it is right; 6. The loose sound is right.
In fact, everyone can simply judge the sound quality, as long as you remember the above points, any speaker will have a basic understanding in front of you.

Second, the version of Bluetooth
First of all, we first understand what Bluetooth is. The so-called Bluetooth technology is actually a short-range radio technology. The use of "Bluetooth" technology can effectively simplify the integration of mobile communication terminal devices such as handheld computers, notebook computers, and mobile phones. Inter-communication can also successfully simplify the communication between these devices and the Internet, so that the data transmission between these modern communication devices and the Internet becomes more rapid and efficient, and broadens the way for wireless communication. So far, Bluetooth has a total of V1.1/1.2/2.0/2.1/3.0/4.0 and other versions. At present, our most common version is V2.1+EDR/3.0/4.0. The three versions are defined as:
Compared to the 2.0 version, the speed is faster, and the theoretical transmission rate of the 2.1+EDR version can reach 2.1Mbps. And joined the "Sniff Subrating" technology. This technology saves power consumption by setting the sending interval of mutual confirmation signals between two devices. For hardware devices that need to continuously transmit data streams, such as keyboards and mice, this technology can extend battery life by up to 5 times.
Compared with the V2.1+EDR version, the theoretical data transmission rate of V3.0 has reached 24Mbps, which can be used for data transmission between high-definition TVs, laptops, tablets and printers. An enhanced power control mechanism is introduced to significantly reduce power consumption when idle.
The most important feature of Bluetooth 4.0 is power saving. The extremely low operating and standby power consumption of 4.0 can make a button battery work continuously for several years, and it has 3 milliseconds low latency, distance of more than 100 meters, AES-128 encryption and many other features. .
So obviously, when we choose Bluetooth speakers, we must choose the higher version of Bluetooth. Everyone should pay attention to this~

Home Bluetooth speakers:
In terms of space, the house is a closed space relative to the outside, which can form echoes. The hearing range of the human ear is 20Hz-20000Hz. The smaller the Hz value of the sound wave, the louder the sound, and the larger the Hz value, the smaller the sound. At this time, the frequency response range of the selected bluetooth speaker is almost 100Hz-20kHz. Such a bluetooth speaker not only satisfies the enjoyment of low sound and light sound, but also satisfies the high-sounding and explosive music.
