Paper, metal, silk, polypropylene - neither of which only now do diffusers speakers. But the use of such seemingly "musical" material like wood, was delayed by as much as 20 years. They waited to have, but helped vodka. |

If the problem involved the Eastern Slavs, the issue would be resolved long ago - because we started with a B what the Japanese finished. But first things first.

The main obstacle in making the speaker cones from a tree specialists JVC encountered in the process of molding. Sheet veneer (thin-layer wood) does not want to take the form of a cone - split, cracked. Tried various stamps, varieties of wood - all in vain, until finally someone did not think to soak the rice harvest in the vodka (sake). Drink soaked birch allowed to do with them anything - to cut, punch, gouge, and domed conical parts. The rest was a matter of technique. Why should such avtoakkustika?

And in the name of what, in fact, such worries? Acoustic properties of wood were seen more masters, who made musical instruments - long before it started to make a case speaker home audio systems. The velocity of sound in wood is high, which provides good detail during playback. Furthermore, in this material are sufficiently large so-called internal losses - that is, the vibration in it are absorbed very efficiently, and therefore the sound get a clean, transparent. This combination of qualities not found in other materials: dominant one or the other (for example, the velocity of sound in aluminum is as high as that of the birch, but the damping of vibrations in the metal close to zero).

According to Japanese engineers, wood has another advantage - the speed of sound in its "body" is not the same. Along the fiber sound goes faster than across. Therefore, the work "wood" speakers rarely formed the so-called standing waves and resonance points. Vehicle dynamics. Accessible to all?

The first line of speakers with the details of birch, known as JVC Wood Cone (born - "a wooden cone"), is designed for high-quality home audio system. Among them - dvuhsantimetrovye vysokochastotniki and mid-bass speakers in diameter from 8,0 to 10,5 cm How sound car speakers with a wooden cone in-car information yet. However, we know that the final phase of your home speaker series JVC Wood Cone company sought the assistance of studio engineer. Obviously, careful calculations and require adjustment and car audio. So avtoinstallyatoram in the fight for a high-quality sound easy life is still not in sight.
