DESCRIPTION JP2003111179
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker mounting bracket, and more particularly to a speaker mounting bracket which can be
easily attached and detached without damaging the speaker itself.
[0002]
2. Description of the Related Art Conventionally, in audio equipment, various developments have
been made to improve the sound quality. One of the desires for such audio equipment is the
acoustic characteristics of the speaker.
[0003]
For example, in the field of home audio, in order to improve the acoustical properties of the
loudspeakers, improvements have been made to the enclosures usually provided together with
the baffles. The enclosure is used to enclose the sound emitted from the back of the speaker and
to prevent the deterioration of the acoustical properties due to the interference of the sound in
front of and behind the speaker.
[0004]

On the other hand, in the field of car audio, it is relatively difficult to obtain an acoustic
characteristic equivalent to that of home audio using an enclosure from the viewpoint of size and
weight reduction of the automobile itself. Instead, the rear speakers used for car audio are
configured to penetrate the rear of the rear speakers into the trunk room and to act as an
enclosure for the trunk room itself. However, the rear speakers can not always obtain the same
acoustic characteristics because the space volume in the trunk room differs depending on the
amount of luggage stored in the trunk room.
[0005]
In addition, in speakers used for car audio, durability more than required for home audio is also
desired. For example, in summer, the temperature in the passenger compartment may rise to
near 90 ° C. in the hot sun while it may drop to below zero in winter. Further, with the speaker
attached to the door trim, there is a risk that the passenger's shoes wet due to rainfall or the like
may touch the speaker. In order to avoid the malfunction and / or the sound quality deterioration
of the speaker due to these, the car audio speaker needs to have excellent durability such as heat
resistance, moisture resistance, water repellency and the like.
[0006]
Further, in recent years, further weight reduction of the car itself and miniaturization of
accessories for securing a wider room have progressed, and along with this, improvement of the
performance of the speaker is also required. For example, an individual setting for sound
pressure characteristics of each channel of speakers disposed at the front, center, and rear for
slowing the difference in acoustic characteristics caused by the seating position of the passenger
is also important.
[0007]
From such a point of view, in the field of car audio, a speaker completely different from home
audio is uniquely developed. As a result, car audio speakers satisfying these requirements have
excellent durability, but must be relatively expensive.

[0008]
According to acoustic characteristics, a total of two to ten speakers such as tweeters and woofers
are provided on a specific interior part such as an automobile door trim, an instrumental panel
and a rear tray. Each speaker provided at these places is usually fixed by a screw or an adhesive.
However, if such fixing is performed, there is a problem that it takes a long time to desorb and
repair the interior parts due to an accident, resulting in poor operability or damage to the
speaker itself. Moreover, even if it considers recycling of each part after scrapping, much time
will be required for removal, and it can not be fully satisfied.
[0009]

and the object of the present invention is to impair the sound quality characteristics of the
speaker in a specific application such as car audio. SUMMARY OF THE INVENTION An object of
the present invention is to provide a speaker mounting bracket which can be easily attached and
detached without reducing the possibility of the speaker being damaged by the attachment and

[0024]
In the bracket 100 of the present invention shown in FIGS. 1 and 2, the base plate 10 and the
hook 12 are formed as separate members, but the present invention is not limited to this
configuration.
That is, in the bracket of the present invention, the base plate and the hook may be integrally
formed.
[0025]
Furthermore, as shown in FIG. 2, the base plate 10 is provided with an opening 14 designed to be
smaller than the frame portion of the mounted speaker.
The opening 14 passes a speaker cable connecting the speaker and an external audio device, and
plays a role of supporting the speaker (specifically, a part of the speaker frame) from behind as
described later.
For example, when attaching a cone-shaped speaker, the periphery of the opening 14 engages
with the frame portion of the speaker to further stabilize the fixation of the speaker.
[0026]
The bracket of the present invention can be used for any speaker provided with a projection
(edge) such that a part of the outer periphery of the speaker frame can be engaged with the hook
from the rear of the speaker.
Examples of loudspeakers mountable by the bracket of the present invention are cone-shaped
loudspeakers and flat-plate loudspeakers, and are used by attaching to distributed mode sound
radiator panels as described in JP-A-11-512262. A transducer type speaker is mentioned.

Examples of more specific cone-shaped speakers include speakers such as curved-cone, flat-cone,
double-cone, ople-cone and parabolic-cone.
Examples of more specific flat panel loudspeakers include Bratt-Haller, Gamuzon and single
Gamuzon speakers.
[0027]
Although the speaker mounting bracket of the present invention is not particularly limited, it is
made of a synthetic resin, metal, wood, or a composite material thereof.
Examples of synthetic resins include thermoplastic resins such as polypropylene, polyethylene,
polystyrene, ABS, polyethylene terephthalate, polyvinyl chloride; and thermosetting resins such
as phenolic resins. Examples of metals include stainless steel, aluminum and copper. An example
of wood is plywood. The bracket of the present invention is manufactured by injection molding,
vacuum forming, pressure forming, casting, or cutting the above material using means well
known to those skilled in the art.
[0028]
Next, the case where a speaker is attached to a rear tray for a car by using the speaker mounting
bracket of the present invention will be described.
[0029]
FIG. 3 is a perspective view of a rear tray of a car in which the speakers are fixed using the
speaker mounting bracket of the present invention.
The speaker mounting bracket 100 of the present invention is, for example, disposed from the
inside (the back side of the drawing) at the position shown by the broken line in FIG. 3 of the rear
tray 40. The mounting position of the bracket 100 to the rear tray 40 is not particularly limited,
and is placed by a person skilled in the art at a position that most effectively improves the
11-05-2019

acoustic characteristics of the speaker as a car audio.
[0030]
FIG. 4 is a schematic cross-sectional view for explaining the bracket of the present invention,
which is disposed in a rear tray of a car and on which a speaker is attached, taken along the line
B-B 'of FIG. Fig. 4) is a view when a cone type speaker is attached, and Fig. 4 (b) is a view when a
transducer type speaker is attached.
[0031]
As shown in FIG. 4 (a), the hook 12 of the bracket 100 of the present invention is a mounting
base 42 (relatively like polypropylene or kenaf) which constitutes the rear tray 40 from the rear
of the cone-shaped speaker 62. The claws of the hook 12 engage with the edge of the frame of
the cone-shaped speaker 62 through a hole 43 provided in the rigid material).
Further, the open portion 14 provided on the base plate 10 of the bracket 100 engages in the
middle of the frame of the speaker 62. As a result, the cone-shaped speaker 62 is securely fixed
by the bracket 100 of the present invention through the mounting base 42 without using any
means such as an adhesive or a screw.
[0032]
The outer surface of the mounting base 42 may also be covered with a skin 44 made of a
material (for example, a synthetic resin such as polypropylene, a fabric or leather) and a
thickness that is unlikely to adversely affect the acoustic characteristics of the speaker. Good.
When the cone-shaped speaker is fixed, the surface material 44 may have a mesh shape at the
position corresponding to the opening portion 14 of the bracket 100, may be provided with a
multi-hole, or may be provided with a slit. It is also good. In (a) of FIG. 4, although the rear tray
40 is comprised by the laminated body of the attachment base material 42 and the skin material
44, it is not limited to this structure. That is, the rear tray 40 may not be provided with a skin
material, or other members made of a material that does not adversely affect the acoustic
characteristics of the cone-shaped speaker may be stacked.

On the other hand, attachment of the transducer type speaker is performed as follows.
[0034]
As shown in FIG. 4 (b), the hook 12 of the bracket 100 of the present invention is a mounting
base 42 (of polypropylene or kenaf as described above, which constitutes the rear tray 40 from
the rear of the transducer type speaker 64). And the hooks of the hooks 12 engage with the edge
of the frame of the transducer-type speaker 64.
On the other hand, the base plate 10 of the bracket 100 contacts and supports the back of the
speaker 64 (which is part of the speaker frame). As a result, the transducer-type speaker 64 is
securely fixed by the bracket 100 of the present invention via the mounting base 42 without
using any means such as an adhesive or a screw. When a transducer type speaker is used, as
shown in (b) of FIG. 4, a hard plate 46 (polypropylene, ABS, or polyethylene terephthalate or the
like, which serves as a diaphragm in contact with the front of the speaker 64). A synthetic resin; a
metal such as stainless steel or aluminum; or a wood such as plywood; is disposed using means
such as an adhesive or double-sided tape.
[0035]
The outer surface of the mounting base 42 may also be covered with a skin 44, as in the case of
the above-mentioned mounting of the cone-shaped loudspeaker. Alternatively, another member
made of a material that does not adversely affect the acoustic characteristics of the transducer
type speaker may be laminated.
[0036]
In this way, the loudspeaker is easily fixed to the desired mounting base using the bracket of the
invention. Although the vehicle rear tray has been exemplified above as the mounting base, the
present invention is not limited thereto, and the instrument panel, door trim, pillar, seat cushion,
seat back rest and roof of the car; movie theater or gallery A partition installed in a conference
room or the like; a ceiling or wall of an underground street; or any other place where installation
of a speaker is desired.

[0037]
The removal of the speaker attached to the mounting base is performed, for example, as follows.
[0038]
Referring again to FIG. 4A, first, the skin material 44 is peeled off from the rear tray 40.
The hook 12 can then be removed from the edge of the speaker frame by manually spreading the
hook 12 of the bracket 100 of the present invention. Thereafter, the bracket 100 is pulled to
release the hook 12 from the hole 43 of the mounting base 42. Thereby, the cone-shaped
speaker 62 is removed from the rear tray 40 very easily. Furthermore, the transducer type
speaker shown in FIG. 4 (b) is also removed from the rear tray in the same manner as the abovementioned cone type speaker.
[0039]
According to the speaker mounting bracket of the present invention, the speaker can be easily
attached to the mounting base of the rear tray or the like. The speakers are merely engaged and
fixed to the claws in the hooks of the bracket of the present invention, respectively. Therefore,
even in the case of repair or replacement, desorption can be performed in a short time, and the
risk of damaging the speaker itself is also avoided. Furthermore, since the removal of the speaker
is extremely easy, recycling of each part can be easily performed.
