2004 V-HI-HAT™
Nishi: The newest generation V-Drum kits (starting with the TD-
20S) featured a new star component: the V-Hi-Hat.
Technically, there were two primary factors in the development of
the V-Hi-Hat.
• To accurately send the impact signal to the sound module.
• To send the information of the open/closed condition
between the top and bottom pads to the sound module.
To meet these goals, we set up the motion sensor in the center
of the bottom pad, and we tried many mechanical structures, such
as optical-type sensors or hall elements at the beginning. Finally we
decided to use a spring to push down the sensor for sending the
open/closed information to the sound module.
For the materials of the V-Hi-Hat, we used the same materials as
the V-Cymbals: an internal base with rubber surface.
In order to improve hi-hat’s sensitivity consistency, we used a
crescent shape part for the top pad. In order to distinguish which
area of edge/bow was high, we used a special sensor for detection.
Therefore, we required only two cables to be connected between
the bottom pad and the sound module, while there is one link cable
between the top and bottom hi-hat pads.
The V-Hi-Hat was developed and produced by a team of six R&D
engineers, which included a mechanical designer, hardware designer,
software programmer, and sound engineer.
Today, the V-Drum legacy of innovation continues with the new
TD-12 drum module with Interval Control, the TD-12S V-Drum kit, and
VH-11 oating hi-hat.
