Let us describe with the manufacturer's XINDAK original words in perfect Chinese English the function principle of this unique sound tuning tool. "It is learned that vibration is arch-enemy affecting acoustic quality. Usually, there are two resolutions. One is absorption; the other is isolation. But, the XINDAK engineers have developed a new device, named as Spherical Cone Base Plate for Vibration Tuning (SCBVT), to solve the damage of acoustic quality because of vibration. Its principle is to convert vertical vibration into horizontal dis-placement. The structure of SCBVT is: Putting a ball in a pit of compact inert material, the base of acoustics put on the ball in form of a point contact. The result is: First it makes play of isolating vibration; secondly, hazardous vibration of acoustics equably spreads inside the whole inert base trough the ball and is absorbed. Meanwhile assortment of the base and the ball material is able to turn hazardous vibration of the former system in frequency point hurtles to acoustic quality. Actual audition has proved adopting bases and balls of different materials gains different effects of acoustic quality and tone color. This fact is used to tune different acoustics by XINDAK damper shackles of different material combinations, covering in this way all the different demands what might occur while tuning various acoustic devices." |
