Technical Field
[0001] This invention is related to a new bridge and production method thereof providing
that sounds with high quality of tone and sound characteristics are obtained as a
result of producing the bridge(threshold) from ram horn and buffalo horn, used in
the violin family which belongs to the stringed instruments. The ram and buffalo horn
bridge increases characteristics and beauty of timbre, an archaized sound quality
is obtained when it is used on the violin, viola, cello and contrabass.
Prior Art
[0002] The main function of the bridge is to transmit the vibration to the sound box, to
resist pressure and tensile force coming from strings. The bridge performs the functions
of strengthening sound, tone, resonance and resisting the force generated by string.
The shape, form and cut of the bridge change according to the nature, properties of
rigidity and flexibility of the wood used and environment where it grows up. The most
important factors affecting the sound vibration are the model of the bridge, space
between feet of the bridge, thinness of its feet and well running of its feet. The
form and processing of the bridge and good materials used are very effective in transmission
of vibration to the sound box. The bridge is made with different sizes in each of
stringed instruments. Depths of the string slots, angle that the bridge feet make
with the sound box are important factors in well sounding. In some countries, bridge
is also called as threshold.
[0003] There are various bridges in the existing technology. Said bridges are made of maple,
which is a wooden material and which is also known as butterfly tree generally in
our country (TR), in certain forms and suitable sizes with stringed instruments. Bridges
are designed on the purpose of increasing the ideal sound and tone quality for violin,
viola, cello and contrabass which are all members of the violin family and providing
the archaized sound quality for instruments. Here, the main point is increasing of
the sound value and financial value of an instrument which is in the violin family
in parallel with increasing of its age.
[0004] Wood is preferred as raw material in the bridges at the state of the art on the purpose
of strengthening sound, tone and resonance. However, this situation sometimes causes
problems like bending, deflection and deforming because of the pressure that strings
apply. Deformation is seen in the bridges produced for violin, viola, cello and contrabass
because of the string pressure that each stringed instrument has in itself. In addition
to deformation, problems like chink sound, wolf also may be met in time. Because this
deformation decreases sound quality in time, operations like changing bridge, reconditioning
or applying heat treatment to the bridge are inevitable. This situation causes difficulties
for people who play stringed instruments and negative conditions like financial problems
and work interruption and most importantly, affects the sound quality of the stringed
instrument negatively.
[0005] There are two types of bridge models used commonly in the world. These bridges known
as French and Belgian models are produced in many countries by fabrication. While
the bridge feet are longer in Belgian model, the feet are shorter in French model.
While they only consists of two different types, sound difference does not exist.
Instrument producers (luthiers) can work with their own style on bridges by making
changes on these two models as they desire. But the main form of bridge remains the
same in any case except of little changes.
[0006] In the German patent (utility model) with the number of
DE20318308U1, a curved top bridge designed symmetrically for supporting string resonance of the
stringed instruments is mentioned. Two feet completely treading on the surface of
sound box at equal distance to both sides of the central line are present to support
the top of the body. A wood bridge is designed such as it has two kidney shaped holes
positioned symmetrically on feet, string slots formed symmetrically for both of two
strings on the top and an opening in the form of isosceles triangle on feet and concave
side edges of the opening such that they hold the feet. In other words, sound problems
are solved by changing design of the bridge of viola, cello and contrabass which are
existing stringed instruments with a deformation preventive design. However, this
design causes difficulty in playing the instrument for the performer because of the
symmetric change made in the stringed slots. Because there is a usual ongoing playing
method.
[0007] Also, an acoustic vibration decreasing system which separates the sound vibrations
of the electric instruments (cello and guitar) is constituted in the European Patent
Office document with the number of
EP1471498A2. According to this system, electrical signals are taken from the sound and vibration
obtained when the instrument is played via a mechanical-electrical converter positioned
just under the feet of the bridge in the box. Here; the main purpose of the bridge,
shortly said invention, is about the solution of the problems like resonance, tone
etc. of the known bridge. In addition, this mechanism can be used also for French
model bridges. However, this type needs to be treated because the electronic mechanisms
may have problems in time. Additionally; the sound obtained is artificial, it spoils
the sound character. The sound obtained is not natural. In the cello and guitar; when
the difference of sound, tone, volume obtained from both of two independent instruments
is considered, usage of the same type bridge and the same mechanism may cause negative
situations. Also, the operation cost will be high because it has a grift design.
[0008] In
WO2010/053810 A1, a bridge made of any suitable comparatively lightweight, acoustically resonant material
including wood, fiberglass carbon fiber, graphite, aluminum, bone, plastic, ivory,
polyborontrinitrate, corian, micarta, phenolic, and their combinations are disclosed.
(page 24, line 16-19) Furthermore,
WO2010/053810 discloses a bridge which allows an electric guitar to deliver authentic acoustic
tone without any pre-amplification or signal conditioning.
[0009] The article in the name of "Instruments used by Aa-Yang ensemble" by Jigme d, mentions
from a buffalo horn which is used to make the two stringed fiddle.
[0010] The document of
FR 2 616 257 A1, discloses bridges for instruments. This bridge consists of the following materials:
polycarbonates, such plexiglass, plexi / crystal, tinted or transparencies, altuglass,
plastic compounds scales of various colors, ultramides, precious metals, and stainless
such as gold, white gold, with platinum, and alloys wave bronzes, brass, ivory and
cleaned bones, plastic materials, shells, scales, stainless, cerasiques, fiber glass
and carbon. The bridges in this document uses a structure which is composed of a lot
of material (described above) wherein the usage amounts and percentages of these materials
is unknown.
The Aim of the Invention
[0011] The aim of this invention is to provide archaizing (tone and character of old instruments)
and increasing of the sound quality of violin, viola, cello and contrabass which are
in the violin family as a result of usage of ram horn and buffalo horn as raw material.
[0012] As a result of the usage of ram horn and buffalo horn as raw material, another aim
of this invention is to remove deformation conditions like deflection, bending because
of the string pressure observed in the bridges in time and situations relating to
this like spoiling sound quality.
[0013] Another aim of the invention is to increase the deformation resistance of the bridge
by performing chemical hardening process to the bridge made of ram horn and buffalo
horn with water and sodium sulfate mixture.
[0014] Another aim of the invention is to provide that the sound in the bridge is more characteristic/qualified
as a result of preferring ram horn and buffalo horn rather than other raw materials
used. The possibility of tang, wolf which is present in wooden bridges is not in question
in the bridges made of ram horn and buffalo horn.
[0015] Another aim of the invention is that mutes (Sordino) used for either orchestra or
individual performance can be used easily in the bridges made of ram horn and buffalo
horn as well as in wooden bridges.
[0016] Another aim of the invention is that the wolf sound problem which may occur in the
violin family (violin, viola, cello, contrabass) especially in the c sharp and f sharp
sounds is exactly not present in the bridges made of ram horn and buffalo horn.
[0017] Another aim of the invention is that when ram horn and buffalo horn is provided in
the sizes suitable for the production of the bridge, either cutting of this raw material
with manual labor or its production by cutting in CNC machines is quite easy and simple.
Therefore, there are not any high costs in its production and processing of the product.
Another aim of the invention is to provide obtaining a much higher qualified sound
than the factory made bridges. These aims are achieved by the appended set of claims.
This invention can be used in all solo instruments and violin family orchestra (violin,
viola, cello, contrabass) instruments. Regardless of the age of instrument, an archaized
sound can be obtained like an old instrument when the bridge made of ram horn and
buffalo horn is used. Therefore; waiting for years is not needed, finding an instrument
which has been used for years and paying high costs are not in question in order to
obtain this archaized sound desired from the instrument.
