[0001] This invention relates to a system for generating a sound and in particular a system,
mainly designed for dance, for generating sounds correlated with dancing.
[0002] In the world of dance, both classic and modern, it is currently very difficult to
develop shows which differ considerably from others since one works mainly on the
styles of the dance itself and not on other aspects.
[0003] For this reason, the need to develop different and attractive shows in the dance
sector also remains unsatisfied for the dancers themselves.
[0004] In this context, the aim is to develop a system for generating a sound which allows
the performance of shows which are significantly different from prior art shows.
[0005] In particular, the aim of the invention is to provide a system for generating a sound
which allows a real change of perspective in dance shows.
[0006] This aim is achieved by a system for generating a sound comprising the technical
features described in one or more of the accompanying claims. The dependent claims
correspond to possible different embodiments of the invention.
[0007] Further features and advantages of the invention are more apparent in the non-limiting
description which follows of a preferred embodiment of a system for generating a sound.
[0008] The description is set out below with reference to the accompanying drawings which
are provided solely for purposes of illustration without restricting the scope of
the invention and in which:
- Figure 1 illustrates a schematic view partly in blocks of a system for generating
a sound according to the invention;
- Figure 2 illustrates a schematic cross-section view of a detail of a first embodiment
of a system for generating a sound according to the invention;
- Figure 3 illustrates a schematic cross-section view of a detail of a second embodiment
of a system for generating a sound according to the invention.
[0009] With reference to Figure 1, the reference numeral 1 denotes in its entirety a system
for generating a sound.
[0010] The system comprises, in the example illustrated, a mat 2 and a mat 3. The mat 2
and the mat 3 are preferably equal to each other, at least in terms of the architecture.
[0011] The mat 2 comprises an electrically-conductive layer 4 and at least one electrically
insulating layer 5 coupled to each other.
[0012] The mat 3 comprises an electrically-conductive layer 6 and at least one electrically
insulating layer 7 coupled to each other.
[0013] The layers 4 and 6 are coupled, respectively, to the layers 5 and 7, for example
by gluing or the like.
[0014] The layers 4 and 6 of the two mats 2 and 3 are electrically insulated from each other.
[0015] According to a preferred embodiment, the layers 4 and 6 are made of conductive rubber
and comprise, for example, a polymeric matrix 8, preferably elastomeric, charged with
an electrically-conductive material 9, for example graphite.
[0016] The electrically insulating layer 5 and/or the electrically insulating layer 7 are
made, for example, of rubber.
[0017] According to an example, the layer 5 and/or the layer 7 are made of high-density
rubber with a thickness of 5 mm.
[0018] According to an example, the layer 5 and/or the layer 7 comprise a bottom support
made of PVC reinforced with glass fibre.
[0019] According to an example, the layer 5 and/or the layer 7 are made of elastomer with
a thickness of 5 mm.
[0020] According to an example, the layer 5 and/or the layer 7 comprise PVC.
[0021] According to an embodiment illustrated for example in Figure 3, the layer 5 and the
layer 7 are made as a single body to form a platform 10 on which the electrically-conductive
layers 4 and 6 are applied.
[0022] In use, the mats 2 and 3 are positioned in such a way that the electrically insulating
layers 5, 7 rest on a floor or on a supporting surface and the layers 4 and 6 face
upwards. In practice, the layers 5 and 7 form a underlayer of the mats 2 and 3.
[0023] At least in use, the layers 4 and 6 are positioned relative to each other in such
a way that a user U, preferably a dancer, can simultaneously touch the electrically-conductive
layer 4 and the electrically-conductive layer 6 carrying them into electrical contact
and defining an electrical resistance R between the layers 4 and 6. The electrical
resistance R depends on the physical characteristics of the user U and how he/she
rests and/or how he/she moves on the mats 1 and 2, for example with the hands, feet
or body.
[0024] The layers 5 and 7 must isolate the layers 4 and 6 from the surrounding environment
in such a way that the electrical connection between the layers is determined exclusively
by the user U.
[0025] Preferably, the layers 5 and 7 are made of a material whose moisture absorption at
saturation is less than 0.8%, preferably less than 0.5%, that is to say, materials
commonly known as non-hygroscopic materials, so as to minimise the absorption of water
in them and maintain the insulating effect at least between the layers 4 and 6 and
the surrounding environment.
[0026] In general, the mats 2 and 3 must provide a good elastic response to stresses and
protect from injuries and excessive muscle fatigue or anti-traumatic strain the individuals
who intends to use the system 1 and in particular to carry out dance routines. According
to alternative embodiments, the insulating layer may be multilayer, that is to say,
it comprises two or more layers coupled to each other on the basis of the performance
expected from the mats 2 and 3.
[0027] The system 1 comprises an interface 11 having an analogue input, indicated in the
drawing with the polarities "+" and "-", and a digital output 12.
[0028] The analogue inlet comprises a positive pole "+" electrically connected to the layer
4 of the mat 2 and a negative pole "-" electrically connected with the layer 6 of
the belt 3.
[0029] The mat 2, in particular the layer 4, and the mat 3, in particular the layer 6, define
electrodes of the system 1.
[0030] The interface 11 is configured to generate a digital signal S1 corresponding to a
musical note as a function of the electrical resistance R measured, the layer 4 and
the layer 6.
[0031] In practice, the signal S1 depends on how the user U occupies and connects the mats
2 and 3 to each other electrically.
[0032] The system 1 comprises a processing unit 13 in communication with the digital output
12 of the interface 11 for receiving the signal S1, that is, the musical note.
[0033] The signal S1 may be, for example, sent to the processing unit 13 using a USB interface.
The processing unit 13 is configured to associate a sound S2 with the musical note;
the sound S2 may be reproduced, for example, by means of a virtual instrument 14.
[0034] According to the preferred embodiment, the interface 11 is a MIDI interface and the
digital signal S1 is a MIDI signal.
[0035] The MIDI signal S1 may also be used to control stage lights using a processing unit,
for example the same processing unit 13, suitably configured.
[0036] Schematically, the MIDI format comprises the interface and software protocols for
generating music; the interface 11 sends MIDI signals which are read by musical software,
present in the processing unit 13, which reproduces it with any selected sound.
[0037] The musical software, resident in the processing unit 13, can reproduce the notes
by means of virtual instruments, for example with the sound of an oboe or a violin,
by means of a synthesiser or a sampling of a recorded sound which is started by means
of a predetermined note.
[0038] The MIDI standard is a musical transcription standard; a MIDI file or message, referred
to as signal S1, contains a series of information that a computer or an electronic
keyboard or the like, such as the processing unit 13, reads and transforms into a
note which is played, for example, by means of a synthesised or sampled sound, using
the virtual instrument 14. In the system 1, the MIDI signals are generated through
the two electrical contacts, defined by the layers 4 and 6, reading the resistance
R.
[0039] When the contacts 4 and 6 are closed, the resistance value seen by the input of the
interface 11 changes and it generates a note with a different level or different notes
as a function of the resistance R.
[0040] The system 1 is therefore able to transcribe into music the movements of the user
U, in particular of a dancer.
[0041] In effect, the dancer, or the dancers, act as an electric bridge between the mats
2 and 3 imposing on the system the resistance R which varies on the basis of the movements
of the dancer him/herself, thus generating diversified sounds.
[0042] By closing the circuit in any way, the level of electrical resistance R is different
and a note of a different height is generated.
[0043] Increasing or decreasing the surface of the body which comes into contact with the
electrodes, or contact surface, varies the electrical resistance and the note therefore
becomes higher or lower based on the resistance.
[0044] The electrical resistance and the musical note therefore depend on a dynamics of
the user who determines the contact surface between the body and the mats 2 and 3.
[0045] For example, the greater the contact surface, the lower is the electrical resistance
R of the circuit and the greater is the intonation of the note generated.
[0046] For example, if the dancer touches the layers 4 and 6 with the tips of the feet a
low note is generated, if pressed with all the foot the note rises, if the dancer
lies with the body across the mats the note becomes even higher.
[0047] Each electrical resistance corresponds to a single note; once the note generated
is sent to the processing unit, it is possible to decide how to use it.
[0048] For example, filters may be applied to raise or lower it, depending also on which
instrument is selected to play the note. For example, it is possible to raise a low
note which is to be played by a clarion.
[0049] The interface 11 may comprise, for example, schematically, a digital analogue converter
15 which defines the analogue input. The converter 15 is configured for sampling an
analogue voltage signal, as a function of the electrical resistance R between the
layer 4 and the layer 6, and to provide a sample signal SC. The interface 11 comprises
a microprocessor 16, in communication with the converter 15, for receiving as input
the sample signal SC. The microprocessor 16 is configured for generating the digital
signal S1 as a function of the sample signal SC and therefore of the resistance R.
[0050] Preferably, the microprocessor 16 and the converter 15 are integrated in a microcontroller
17.
[0051] The solution as described herein brings important advantages. The system described
allows the dancer to create the music without always being forced to follow one. It
is possible to set up shows which are completely different from prior art shows since
traditional situations can be combined with others diametrically opposite each other.
It completely changes the perspective compared with prior art shows; it is no longer
the music or it is not just the music that guides the dance but it is the dancer who
can compose a symphony with the dance; the dancer creates movement and music.
