Haman speaker, do not underestimate the speaker material!

Speaking of speakers, to pay attention to two points, one is the price, one is the sound quality. Needless to say the price, how much money do many things; and this thing sound becomes a bit iffy, involved in something more, such as unit, component, and so on...... But few people to pay attention to the speaker in all aspects of the material problem.

In fact, both the speaker speaker unit or the appearance of the material with the development of audio and constantly changing, and different materials not only affect the appearance of the speaker, but also has great effect on the sound from the speakers!

Multiple unit material

From the sound box structure, most of the multimedia speakers are dual unit two frequency design, a smaller speaker is responsible for the output of the treble, while the other is responsible for the larger subwoofer output. So the two parts of the unit in the design is also very different.

There are several kinds of membrane materials in the top of the soft top, such as silk film, silkworm thread film, rubber film and bulletproof cloth. The treble unit of the soft top of the ball, which has a very good natural expression, is capable of reproducing the music. In recent years, from the perspective of the high unit material, silk film, silk membrane has become a common material in high-end products.

Of course, some manufacturers are also trying to improve the quality of the treble unit material, want to use some different materials to create a better quality. For example, CAV in the top HiFi speakers on the use of ceramic magnesium smelting unit, greatly improving the rigidity of the diaphragm.

HiFi high-end boxes usually have more stress on the unit material

As for the bass unit, choose to pay more attention to some. The past common paper pots, plates cloth, wool making pots and pots and other PP materials, a variety of different materials can also create a different bass effect, the paper basin should be said to be the mainstream in the HiFi speakers, meet the eye everywhere.

Of course, with the needs of the people, there are now a number of aluminum, magnesium metal sound basin. In the basin, mainly the use of metal materials to build, see comparison have iron pots and aluminum pot.

Many speakers using aluminum frame

Relatively low cost of iron pots, aluminum pots cost is much higher. From the technical point of view, the iron basin is a stamping molding, and aluminum frame is to cast aluminum, polished, more cumbersome. The advantage of the iron basin is the small dynamic distortion is relatively small, while the aluminum basin in the large dynamic performance is far stronger than the iron basin, but the small dynamic distortion rate is higher.

But in recent years some manufacturers launched speakers, mostly in the bass unit use aluminum pots, such as a variety of products are used saunterer aluminum pots, this is because in addition to good dynamic effect, anti made of aluminum pots and sensitivity are stronger than iron pots, taking into account the extensive application in the multimedia speaker so now, manufacturers in the bass unit on the use of aluminum pots can also be not at all surprising the basket.

The significance of different box material

In addition to the change of the material, the material is very important for the sound box. We often see the speaker box material, nothing more than two kinds of wood and plastic. Good damping characteristics of wood material, the sound quality is soft, but less rigid, reproducing bass there is always a messy fuzzy sense, many HiFi speakers also hope to solve this problem through various technical means; and easy processing, plastic molding, the first baffle into complex shapes for sound diffusion, but the intensity of not enough, sound-absorbing performance is poor. Two kinds of materials have their own advantages and disadvantages, but all aspects of integration, they are still the most mainstream speaker box material.

Ceramic box is also reflected in the more common

Of course, in addition to these two kinds of materials, speakers and many other materials can be used. Typical examples are stone, glass, ceramics and concrete. The stone material marble, granite, generally have high strength and sound transmission characteristics of the low rate, as the speaker, the sound level sense, telepresence is better, but the processing difficulty is big, and the box itself on the acoustic damping effect is minimal; glass box resonance is very low, the sound quality is clear and transparent, with a mirror pure bass, and the appearance of a lot of extra points, but it is also a difficult processing and acoustic damping characteristic difference; as for the ceramic box, solve a lot of problems and sound processing, shaping easier, mellow sound sweet, in addition to the acoustic damping characteristics in general, weakness is not obvious. Now many Bluetooth speakers are made of ceramic materials to do speaker box.

Concrete box has many advantages, but the weight is very exaggerated

It is likely to become the future concrete material material mainstream, concrete hand, easy processing, damping and sound characteristics can be achieved through work and shaping, and the appearance can be very delicate, but may be the weight will have a problem, but it seems to use the material box is not many.
