Speaker mounted liquid crystal display
[0001]
BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a
liquid crystal display device (liquid crystal television etc.) equipped with a speaker.
[0002]
In a liquid crystal television equipped with a speaker, the contact sound (unusual noise) between
the speaker vibrating by sound emission and the cabinet of the liquid crystal television has
become a problem.
As an example of solution to this problem, it is conceivable to interpose a vibration isolation body
as shown in Patent Document 1 between a speaker and a cabinet.

[0004]
However, such an antivibration body is expensive, which leads to an increase in the cost of the
liquid crystal television.
Moreover, the process of interposing such a vibration-proof body between a cabinet and a
speaker is very troublesome.
[0005]
The present invention has been made in view of the above situation. An object of the present
invention is to provide a speaker mounted liquid crystal display device in which the contact noise
between the speaker and the cabinet is prevented by a simple mechanism as well as simplifying
the manufacturing process.
[0006]
The present invention is a speaker mounted liquid crystal display device including a speaker and
a cabinet including a speaker receiving unit that holds the speaker. In the speaker mounted liquid
crystal display device, the speaker includes a gasket, the speaker receiving portion includes a rib
in contact with the gasket, and the rib is on one surface facing the gasket by the rib include.
[0007]
And it is desirable that the raised pieces have a shape that allows line contact with the gasket. For
example, triangular prismatic raised pieces may be mentioned. In addition, the shape of such a
whole protrusion and arrangement | positioning of a protrusion are variously assumed. One such
example is as follows.

[0008]
For example, if the gasket is ring-shaped, the ribs are also ring-shaped, and the ridges are
arranged on one side facing the gasket at the rib.
[0009]
And while each protruding piece is formed into a ring by connecting one triangular prism, it is
preferable that the protruding pieces are arranged concentrically in the protruding piece group
in which a plurality of the protruding pieces are gathered.
[0010]
However, the present invention is not limited to the concentric arrangement. For example, each
of the raised pieces is a single triangular prism, and the raised pieces may be arranged radially in
a plurality of raised pieces including a plurality of raised pieces. .
[0011]
Moreover, as another example, the raised pieces may be in a spiral shape by connecting one
triangular prism.
[0012]
The raised pieces are not limited to triangular prisms.
For example, it is desirable that the protruding pieces have a shape that allows point contact with
the gasket.
One example is a protruding ridge.
And as arrangement | positioning of such a convex-shaped protruding piece, it is desirable for it
to be scattered by the rib in the surface facing a gasket.

According to the present invention, the protruding pieces come into contact with the gasket, and
the degree of fixation between the rib containing the protruding pieces and the gasket is
increased.
Therefore, even if the speaker vibrates, no displacement occurs between the rib and the gasket,
and consequently between the speaker receiving portion and the speaker, and no abnormal noise
is generated due to the displacement.
[0014]
Moreover, due to the high degree of fixation between the rib and the gasket, repeated occurrence
of contact and separation between the gasket and the rib does not occur even if the speaker
vibrates. Therefore, no abnormal noise occurs due to this phenomenon.
[0015]
First Embodiment One embodiment will be described below with reference to the drawings. In
addition, although the code | symbol of a member, hatching, etc. may be abbreviate | omitted for
convenience, in this case, another drawing shall be referred. Also, depending on the drawing,
hatching may be applied for convenience, though it is not a cross-sectional view.
[0016]
The perspective view of FIG. 10 shows a liquid crystal television (liquid crystal display) 49. The
liquid crystal television 49 includes a speaker SP, as shown in FIG. The speaker SP is attached to
the front side (front cabinet FCB) of the cabinet CB in the liquid crystal television 49.
[0017]
Specifically, as shown in FIG. 11 and FIG. 12 showing the inside of the front cabinet FCB, the
12-05-2019
4
speaker SP is fastened to the speaker receiving portion 11. (FIG. 11 shows a state in which the
speaker SP is mounted, and FIG. 12 shows only the front cabinet FCB).
[0018]
The speaker receiving portion 11 includes a rib 12, and the rib 12 is also referred to as a gasket
21 (also referred to as a blind) provided at the edge of the sound emission opening H of the
speaker SP shown in the perspective view of The same shape. This is because the rib 12 and the
gasket 21 come in contact with each other to prevent the sound from the sound emission port H
from leaking in a direction other than the desired direction.
[0019]
Here, the rib 12 will be described in detail with reference to FIGS. 1 to 3. FIG. 1 is a partial
perspective view of the rib 12, and FIG. 2 is a plan view of the rib 12 viewed from the front side
(see the arrow direction in FIG. 12). 3 is a cross-sectional view taken along the line A-A 'of FIG. 2
(however, for convenience, the gasket 21 is also shown).
[0020]
As shown in FIGS. 1 to 3, one surface 12 a (the top surface 12 a; see FIG. 12) facing the gasket
21 at the rib 12 includes a protruding piece BG. It is desirable that the protruding pieces BG have
a shape that allows line contact with the gasket 21. For example, as shown in FIG. 1, a triangular
prismatic raised piece BG can be mentioned. With such a shape, if one side L along the column
direction faces the gasket 21, the gasket 21 is in linear contact with the gasket 21.
[0021]
In addition, the shape of the whole protruding piece BG is assumed variously. For example, as
shown in FIG. 13, in the case where the gasket 21 has a ring shape (Wan shape), the rib 12 also
has a ring shape. Therefore, on the surface 12a facing the gasket 21 by the ribs 12, as shown in
FIG. 2, each raised piece BG is formed into a ring by connecting one triangular prism, and the
ring-shaped raised piece BG It is good to have multiple In particular, when a plurality of raised
12-05-2019
5
pieces BG are taken as a raised piece group, it is preferable that the raised pieces BG be arranged
concentrically in the raised group.
[0022]
In this case, as shown in FIG. 3, the protruding piece BG comes into contact with the gasket 21
and the degree of fixation between the two (between the rib 12 including the protruding piece
BG and the gasket 21) increases. As a result, even if the speaker SP vibrates, no deviation occurs
between the two (no abnormal noise due to this deviation is generated).
[0023]
In particular, in the direction (for example, the in-plane direction V of the ring of the annular
gasket 21) in which the protruding pieces BG cross the direction in which the protruding pieces
BG are stuck, even if the speaker SP vibrates The inside of 21 will be in contact with the side of
raised piece BG. Therefore, the gap between the two in this direction does not occur even more.
[0024]
Moreover, in the liquid crystal television 49, the gasket 21 vibrating due to the vibration of the
speaker SP remains in contact with the rib 12. Therefore, due to the vibration of the gasket 21,
repeated phenomena of contact and separation between the gasket 21 and the rib 12 do not
occur. Then, the noise caused by this phenomenon does not occur either.
[0025]
Moreover, such a liquid crystal television 49 does not have to make the gasket 21 an expensive
and soft cushion. This is because, even if the gasket 21 is relatively inexpensive and hard and
made of paper, if there is the protruding piece BG of the rib 12 in the speaker receiving portion
11, the rib 12 and the gasket 21 and by extension It is because a gap does not occur.
[0026]

Further, such a liquid crystal television 49 may not have a vibration isolation body between the
speaker SP and the front cabinet FCB. Therefore, attachment of the speaker SP to the front
cabinet FCB is facilitated. In addition, the cost of the liquid crystal television 49 can be reduced
because the antivibration body is unnecessary.
[0027]
Note that examples of the shape of the entire bulged piece BG include the examples shown in
FIGS. 4 to 6 (note that FIGS. 4 and 5 are the same expressions as in FIGS. 1 and 2, and FIG. It is a
BB 'arrow sectional view). That is, each raised piece BG is a single triangular prism, and the raised
pieces BG may be radially arranged in the raised piece group in which a plurality of raised pieces
BG gather.
[0028]
Further, although not shown, the raised pieces BG may be in a spiral shape by connecting one
triangular prism.
[0029]
By the way, the protruding pieces BG themselves are not limited to the above-described linecontactable triangular prisms.
For example, as shown in FIGS. 7 to 9, the protruding pieces BG may have a protruding shape
that allows point contact with the gasket 21 (note that FIGS. 7 and 8 are similar to FIGS. 1 and 2).
, And FIG. 9 is a cross-sectional view taken along line CC ′ of FIG.
[0030]
And if it is such protruding convex piece BG, as shown to FIG. 7 and FIG. 8, it is scattered by one
surface 12a of the rib 12 which touches the gasket 21. As shown in FIG. The point is that in the
speaker mounted type liquid crystal television 49, the speaker SP includes the gasket 21 and the
12-05-2019
7
speaker receiving portion 11 includes the rib 12 in contact with the gasket 21. The surface 12a
facing the surface 21 may include, for example, a ridge BG capable of line contact or point
contact.
[0031]
[Other Embodiments] The present invention is not limited to the above-described embodiment,
and various modifications can be made without departing from the spirit of the present
invention.
[0032]
For example, the protruding pieces BG may have a shape other than a triangular prism or a
protrusion.
The point is that any shape may be used so long as it is pierced on one surface of the gasket 21
facing the rib 12. Therefore, the raised pieces BG may be conical (conical, polygonal pyramid,
etc.) or frustum (conical, polygonal pyramid).
[0033]
Moreover, as processing of the rib 12 containing the protruding pieces BG as described above, a
method such as embossing is mentioned.
