Whether you are an audiophile or an ordinary music lover, there will be a stereo in the home, although it is always used, but not everyone understands and understands their own audio. This article, the main thing is to popularize science with you, our cold knowledge of Bluetooth audio, and then Xiaomai will talk to you one by one

First of all,
our audio actually has many kinds of materials, including wood, plastic, glass, metal and other materials

Wood material: we have previously popular wooden audio, wooden cabinet is not equivalent to pure wood, wood panels can be divided into solid wood panels, wood-based panels according to the material classification

Plastic material: It is now used by many Bluetooth speakers, because plastic materials have the characteristics of light weight and strong plasticity. After special design or the use of special plastic materials, and with good process guarantee, better acoustics can be achieved.

Glass material: This kind of sound is not ordinary glass, but a fashionable plexiglass. Unlike glass in the traditional sense, it is not as fragile as we think, and its material has better transparency, chemical stability, mechanical properties and weather resistance.

Metal material: At present, it is actually quite a common material, it can create a more vivid sound, and its texture is also in line with the current people's aesthetic standards, and the small and convenient sound is the most widely used.

Next, let's talk to you about the position of our audio placement at home and pay attention to how to place the most scientific Harbin
speakers

The first method: the three-one-seven ratio method
: divide the length and width of our room into three equal parts (three), then place the speakers at a third (one) in length, and then remember that if there are two speakers, the interval should be 0.7 times the length of the room (seven). The sound should preferably have a slight inward angle, if it can't be inward, it's okay, but the listening position should not be close to the back wall. So what does that do, for a space with a large and uniform proportion of the room, which allows us to get a balanced timbre field.

The second method: the three-three-one proportional method
: divide the length and width of our room into three equal parts (three), and then place the sound on the first equal intersection of length and width, and the same listening position can not be against the back wall, so what effect can this produce, in fact, similar to the three-one-seven method, it can also allow us to get a balance of a timbre field.

The third method: screw hole pendulum method
: put the speaker in the middle of the room, and then try to lean the speaker against the wall, if there are two speakers, the inward projection angle of the speaker must be greater than or equal to 45°. Then the listening position needs to be within 1 meter after the intersection of the projection crosshair, but it cannot be less than 0.5 meters, so that our speaker can reduce the sharpness of the treble, the bass is not enough and other sound effects are disadvantages, so that we have a better sense of hearing.

The fourth method: equilateral triangle method
: the first condition requires that the sound and the back wall are separated by more than one meter, and the side wall is separated by half a meter. The second condition is to form an equilateral triangle between the two speakers and the listening position. The third condition is that the inward projection angle of the two speakers should also be greater than 45°, and the fourth condition is that the regular triangle changes with the size of the room. Doing this can further reduce the interference of wall reflection on sound, so that our hearing has a better sense of positioning and a deeper sound field, which is the most listened and the most detailed way to pose.
