[0001] The present invention relates to a loudspeaker stabilizing system. More particularly,
the invention relates to an apparatus, system and a method for stabilizing a loudspeaker.
Background
[0002] In recording studios, loudspeakers are most often placed directly on shelves or on
various types of stands. When the loudspeaker is activated, energy from the loudspeaker
causes the loudspeaker to vibrate, which in turn causes the shelf to resonate, due
to direct acoustic coupling. This causes unwanted resonant frequencies to pollute
the signal and results in forward energy loss, resulting in a reduced transient response.
[0003] Recording studio engineers and audio enthusiasts have been trying to achieve high
quality sound reproduction by seeking out the very best loudspeakers to suit their
musical preferences. In an illustrative case of a studio engineer, once a speaker
has been selected, the engineer will typically bring his speaker to various studios
in effort to provide a "starting point" for consistent and repeatable sound reproduction.
The impact of uncontrollable factors such as room acoustics and speaker placement
may be minimized by using near field monitors. These are generally mounted on top
of a mixing console, within, for example, two meters of the engineer's sitting position
so that the direct sound generated by the loudspeakers dominates over and above any
reflected or ambient sound within the room.
[0004] It is well documented that speakers, when placed on top of a solid surface such as
a desk, shelf, speaker-stand or mixing console, will couple with the mechanical structure,
which imparts a sonic signature to the speakers. For instance, a shelf may resonate
at 100 Hz (100 cycles per second) when a bass note is played by the loudspeaker. As
a consequence of the mechanical coupling between the speaker and the shelf, a 100
Hz peak will also be audible. One solution to this problem has been to isolate a loudspeaker
from the mechanical structure by utilizing a soft urethane foam pad. Others have also
presented options such as placing the loudspeaker on top of sand granules as a means
to decouple the device and/or by suspending the speaker in the air with wires.
[0005] In all these cases, the loudspeaker is "suspended" to prevent the transfer of energy
and therefore to eliminate resonance phenomena. But this in itself creates a new problem.
The speaker is no longer stable, since it is left to "float" or sway. The float or
sway condition causes a movement of the speaker in response to the energy impulse
to be transformed by the loudspeaker and introduced into the sound to be reproduced;
in other terms, there is an impairment of the transient response of the loudspeaker.
This problem may be understood by imagining the recoil generated by a rifle, when
fired. The energy during the explosion forces the bullet out of the barrel while the
rifle itself recoils back reducing the forward energy. If one were to fix the rifle
so that the recoil would be eliminated, it would at once increase the forward energy
but likely destroy the rifle after repeated use.
[0006] A loudspeaker is basically made of an electromagnetic motor that drives a piston.
As the speaker is energized with current, the piston moves to create sound. The sharper
the transient wave, the more quickly and precisely the speaker should react. When
the loudspeaker is suspended or placed on the top of a "movable" or "soft" material,
the forward momentum that would normally produce a distinct transient is softened
(reduced) as the speaker recoils backwards. The result is a less distinct transient.
This affects both low frequencies which produce bass and punch, and high frequencies
which convey spatial information. Accordingly, there is a need for new apparatus,
system and method for stabilizing a loudspeaker.

[0035] Throughout the drawings and the description, the same drawing reference numerals

Detailed description of preferred embodiments
[0036] The following detailed description is provided to assist the reader in gaining a
comprehensive understanding of the apparatuses, methods and/or systems described herein.
Accordingly, various changes, modifications, and equivalents of the apparatuses, systems
and/or methods described herein will be suggested to those of ordinary skill in the
art. Also, descriptions of well-known functions and constructions are omitted to increase
clarity and conciseness.
[0037] Fig. 1 is a diagram illustrating an exemplary speaker stabilizer 100 for stabilizing
a speaker (shown in fig. 3) with respect to a surface. As illustrated in fig. 1, the
speaker stabilizer comprises: an isolation portion 110; a stabilizing platform portion
120; immobilizing means 130, connected to said stabilizing portion; a retaining surface
portion 140; and an impedance or resonance preventing portion 150.
[0038] The isolation portion 110 may act as, for example, a base medium. The isolation portion
110 may be any type of dampening material and may be produced in various shapes to
meet the demands, and angled to direct the speaker (shown in fig. 3) to the optimum
listening position. In the example of fig. 1, the isolation portion 110 mechanically
isolates the speaker (shown in fig. 3) and the stabilizing portion 120 from hard surfaces
which in turn could resonate and introduce artefact into the sound field. In one implementation,
the isolation portion 110 may be produced using a high-density urethane foam but may
also be produced using any type of energy-absorbing substance, such as soft, isolation
or dampening material, spring or other insulating substance such as sand (granular).
The isolation portion 110 may decouple the speaker from the hard surfaces such as
a desk, shelf, or meter bridge to prevent resonance from the speaker transferring
to, for example, the desk, and stops the resonant frequency of the desk from interfering
with a musical playback of the speaker. The isolation portion 110 also acts to provide
vibration damping for the stabilizing platform 120.
[0039] The stabilizing platform portion 120 provides mass to the speaker system to provide
a stabilizing effect. The stabilizing platform portion 120 may be of any heavy rigid
mass or any material whose weight will provide a stabilizing effect to the speaker
system. In one implementation, the stabilizing platform portion 120 may be produced
from steel, lead, concrete, granite, stone, or any other heavy material whose weight
will sufficiently increase the overall mass of the speaker system. For example, heavy
6 mm laser-cut steel may be used to implement the stabilizing platform portion 120.
When the speaker is stationary, the energy transfer to the speaker is forward and
not lost due to the soft underpad. This improves the transient response which in turn
improves the bass performance, sonic detail, and dept of field. As shown in fig. 1,
a flange 122 may be provided to further increase the mass. The flange 122 may increase
the weight while keeping the physical footprint smaller and/or used to control the
ratio in mass of a speaker to speaker stabilizer (100) to a predetermined ratio. In
the example of fig. 1, the stabilizing platform portion 120 is dampened by sandwiching
it between an isolation portion 110 and the retaining surface portion 140 as a means
to reduce and prevent resonance or ringing. In further embodiments, this may be further
augmented by introducing impedance changes in the medium such as changing the mass
in various locations by, for example, cutting holes in the stabilizing platform portion
120, increasing the mass in certain areas and/or by altering the shape of the stabilizing
platform portion 120.
[0040] The immobilizing means 130 is provided to hold and immobilize the speaker in a desired
position with respect to the stabilizing portion. According to a preferred embodiment,
such immobilizing means comprises at least one anchor retainer plate, connected to
the stabilizing portion, provided with attachment devices suitable to hold and immobilize
the speaker in a vice-like and adjustable way.
[0041] According to exemplary embodiment shown in fig. 1, such immobilizing means 130 comprises
two side anchor retainer plates 132, each of which provided with several screw holes
133, where several screws 134 are used to secure a loudspeaker in place by tightening
the screws against the loudspeaker. Loudspeakers of various sized can be secured,
because the screws 134 can be more or less tightened for this purpose. The screws
134 can be adjusted to precisely "aim" a particular loudspeaker to be stabilized and
to allow the loudspeaker to be placed in different positions (e.g., "rotated" with
respect to an axis perpendicular to a base surface).
[0042] According to a particular embodiment, the anchor retainer plates 132 employ an angular
cut to eliminate ringing or self-resonance.
[0043] In a further particular embodiment, some of the screw holes 133 may be used to secure
a safety chain the loudspeaker.
[0044] In accordance with a further embodiment, the immobilizing means may be exploited
to achieve a further advantageous effect, in addition to its main function of holding
and immobilizing the speaker in a desired position: such immobilizing means, in particular
the anchor plates 132, may further increase the mass and weight while keeping the
physical footprint smaller. In fact, once respected the basic specifications of the
anchor plates 132 (necessary to achieve the main function of "immobilizing means"),
there are still degrees of freedom in the size, form, weight of such anchor plates,
to be properly used in the design of the speaker stabilizer to control the ratio in
mass of a speaker to speaker-stabilizer to a predetermined ratio, that is to further
improve the stabilizer performances. In other terms, the selection of a value for
the mass, and/or for the form of the plates allows to "tune" the apparatus design
in order to properly prevent resonance.
[0045] The retaining surface portion 140 may serve to receive the speaker (shown in fig.
3). In one embodiment, the retaining surface portion 140 may provide additional dampening
of the stabilizing platform portion 120. The retaining surface portion 140 may be
any form of applied surfacing material that may dampen the stabilizing platform portion
120 while providing added friction for the speaker. According to an embodiment, the
retaining surface platform can be a no-slip-pad on the upper surface of the apparatus.
The no-slip-pad can be implemented for example as a coating with a thin non-slip neoprene
pad or any other type of treatment that can increase friction. The retaining surface
platform 140 and its thickness may be provided as to provide a cushion for the speaker
to prevent sliding around, while ensuring a positive coupling to the stabilizing platform
portion 120.
[0046] The impedance or resonance preventing portion 150 may be provided to prevent resonance.
In the example of fig. 1, the flange 122 is also cut to an irregular shape to prevent
the chance of the flange 122 vibrating or ringing at a specific frequency, and serves
as the impedance or resonance preventing portion 150. The standing waves or resonance
of the stabilizing portion 120 and the flange 122 is further reduced by providing
an irregular shape or altering the size. In the example of fig. 1, the occurrence
of standing waves or resonance of the stabilizing platform portion 120 is dampened
by the isolation portion 110, by the immobilizing retainer means 140. To further reduce
the opportunity for vibration, the irregularly shaped front flange 122 is provided
which adds an uneven mass to the stabilizing platform portion 120. This makes it difficult
for a standing wave to exist as the inner vibrations cannot reach a stable or predictable
resonating frequency. The front flange 122 is also dampened by the adjacent isolation
portion 110.
[0047] Fig. 2 shows a further embodiment of the invention, including an isolation portion
110, a stabilizing portion 120, immobilizing means 130, and a resonance preventing
portion 150, wherein said elements 110, 120, 130, 150 are the same as described for
fig. 1.
[0048] Fig. 3 shows a further embodiment of the invention, which differs from the ones describes
in fig. 1 and 2 because the isolation portion is shaped in such a way to allow the
stabilizing portion 120 being not parallel to the base surface, i.e., being "angled"
(angle a) with respect to said surface. This can be exploited in cases where the optimum
position of the loudspeaker has to be "angled" e.g., with respect to a floor (and
therefore, with respect to a listening position). This can be realized thanks to the
function performed by the immobilizer means 130, that can properly hold a loudspeaker
also in the mentioned "angled" position. Thanks to this feature, the loudspeaker can
be angled both "up" and "down" with respect to a plane parallel to a floor.
[0049] Fig. 4 shows an exemplary system according to the present invention, comprising a
speaker 200 and a speaker stabilizer 100 according to the embodiment described in
fig. 1.
[0050] Fig. 5 shows a further exemplary speaker stabilizer embodiment according to the present
invention for stabilizing a speaker with respect to a ceiling. The apparatus in fig.
5 comprises:
- a stabilizing portion 120, characterized for example as described in the embodiment
of fig. 1;
- immobilizer means 130, characterized for example as described in the embodiment of
fig. 1;
- wire means 160 for suspending to the ceiling, including wires 161 and hanging points
162; four wires attached via four hanging points to the stabilizing platform body
are shown in the exemplary embodiment of fig. 5. In a further embodiment, the hanging
points 162 are attached to the anchor plates of the immobilizing means 130. In another
embodiment, the number of wires is different from four.
[0051] In accordance with the embodiment shown in fig. 5, the speaker stabilizer (and therefore
the speaker) are suspended through suspending means, for example cables, for example
to the ceiling, at a desired height and angle for optimum placement.
[0052] Fig. 6 shows a further exemplary speaker stabilizer embodiment according to the present
invention for stabilizing a speaker with respect to a ceiling. The apparatus in fig.
6 comprises:
- a stabilizing portion 120, characterized for example as described in the embodiment
of fig. 1;
- immobilizer means 130, characterized for example as described in the embodiment of
fig. 1;
- an isolation portion 110, characterized for example as described in the embodiment
of fig. 1, below the stabilizing portion;
- a supporting plate 170, provided at the base of said isolation portion;
- wire means 160 for suspending to the ceiling, including wires 161 and hanging points
162; four wires attached via four hanging points to the supporting plate 170 are shown
in the exemplary embodiment of fig. 6.
[0053] In accordance with the embodiment shown in fig. 6, the speaker stabilizer (and therefore
the speaker) are suspended through suspending means, for example cables, for example
to the ceiling, at a desired height and angle for optimum placement.
[0054] Fig. 7 shows an exemplary system according to the present invention, comprising a
speaker 200 and a speaker stabilizer 100 according to the embodiment described in
fig. 5.
[0055] While the construction of a speaker stabilizer has been shown to comprise two to
seven components, it will be understood that this is only an illustration of one of
the many embodiments of the present invention. In one implementation, a speaker stabilizer
may comprise three components or layers: an isolation component or layer; a stabilization
platform component or layer; and a retaining surface component or layer. In another
implementation, for example, additional isolation or stabilization may be achieved
by adding additional component(s) or layer(s) to the speaker stabilizer design. For
example, two different steel plates may be provided as a single assembly to form the
stabilizing platform portion, or multiple layers of steel or other stabilizing mass
may be used to introduce a greater degree of "impedance mismatch". Even greater effect
may be achieved by providing each plate, layer, or mass element of different weight
(mass) as the energy will not sympathetically vibrate between them, that is, the vibration
will be out of sync due to different resonant frequency.
[0056] Still yet in another implementation, a speaker stabilizer may comprise the use of
an isolation medium with a stabilizing platform that is in turn coated with a non-slip
surface. In another implementation, a speaker stabilizer may comprise a support and
isolation structure. By increasing the mass of the stabilizing platform support and
isolation structure, the speaker is presented with a stable platform that requires
more energy to set into motion, relative to that of, for example, an isolation portion,
while being isolated by the isolation portion of the structure.
[0057] Yet in another implementation, a predetermined mass relationship of, for example,
a speaker stabilizer, a stabilizing platform portion of the stabilizer, a front flange
of the stabilizer, anchor retainer plates, and the speaker is provided to create an
impedance mismatch or unpredictable set of mass variants that will prevent resonance.
For example, a speaker stabilizer is provided to have a different mass than that of
the speaker so that they will not vibrate in sympathy. As a further example, a speaker
stabilizer may be provided such that a speaker to speaker-stabilizer mass of 4:1 is
achieved, for example, providing a speaker stabilizer with 5 Kg in weight for a loudspeaker
with 20 Kg in weight. Indeed, the higher the mass of the apparatus in comparison to
the loudspeaker, the greater is its effect. According to a particular embodiment,
as a particular advantageous case, it has been found that when one follows a 1 to
4 ratio, whereby the mass of the apparatus is ΒΌ the mass of the loudspeaker, the resulting
effect is very satisfactory.
[0058] Furthermore, while the use of loudspeakers in recording industry is disclosed, it
is understood that the present invention applies to the use of loudspeakers in all
types of listening environments and applications including residential audio systems,
commercial sound, and the like. It is understood that the term loudspeaker or speaker
is used interchangeably and it can refer to individual devices (or drivers), and complete
systems consisting of an enclosure incorporating one or more drivers and additional
electronics. It is also understood that the present invention may be produced in a
variety of ways. As an illustrative embodiment, one or more components or layers of
a speaker stabilizer may be laminated, or integrated in a structure such that, for
example, a portion of the structure isolates a speaker while another portion stabilized
the speaker, while another portion immobilizes the speaker. Moreover, in a speaker
system, a speaker stabilizer of the present invention may be applied to a loudspeaker
itself, for example, introduces as a base of the loudspeaker.
[0059] According to certain embodiments described above, movement caused by the speaker,
and the ensuing counter-effect, i.e., recoil, are significantly reduced. A given medium
may resonate at one or more frequency based in its size, shape, mass and the energy
that may excite it. By controlling the size, shape, mass, and form a speaker stabilizer
and its elements, as described above, the outcome is clearer more distinct audio throughout
the listening range.

portion.

of the apparatus, a hole, a change in mass, a change in size, and/or a change in shape
is provided to prevent resonance.

portion between the speaker and the stabilizing portion to dampen the stabilizing
portion.
[0072] According to a further embodiment, the speaker system comprises a stabilizing portion
requires more energy to set into motion, relative to that of the isolation portion,
to stabilize the speaker.
[0073] According to another embodiment, the speaker stabilizer is provided to a base of
the speaker.
[0074] According to another embodiment, in the speaker system, the mass of the speaker stabilizer
is different than that of the speaker to prevent resonance.
[0075] According to a further embodiment, the ratio of mass of the speaker and speaker-stabilizer
is 4:1.
[0076] In accordance with an embodiment of the present invention, a method of stabilizing
a speaker with respect to a surface, comprises: providing an isolation portion to
isolate the speaker from the surface; and providing a stabilizing portion between
the speaker and the isolation portion to stabilize the speaker.
[0077] According to another method embodiment, said method further comprises providing a
retaining portion between the speaker and the stabilizing portion to dampen the stabilizing
portion.
[0078] In accordance with another method embodiment, the providing of the stabilizing portion
requires more energy to set into motion, relative to that of the isolation portion,

[0079] In accordance with a further method embodiment, the providing of the isolation and
stabilizing portions comprise providing a hole, a change in mass, a change in size,
