DESCRIPTION JPH069274
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
dome speaker mounting apparatus for a television receiver.
[0002]
2. Description of the Related Art In recent years, in a television receiver, a root has been provided
on the side of a wooden cabinet, and a dome speaker has been temporarily held and fixed with a
fitting. A sponge was glued between the plate on the front of the wooden cabinet and the dome
speaker to prevent sound leakage and chattering
[0003]
Hereinafter, a conventional dome receiver for a television receiver will be described with
reference to FIG. In FIG. 5, 31 is a dome speaker, 32 is a wooden cabinet, 33 is a screen, 3a is a
root for temporarily holding the dome speaker, and 34 is a sponge. The dome speaker 31 is
inserted into the dome speaker temporary holding root 3a of the wooden cabinet 32, and the
sponge 34 is attached to the gap between the dome speaker opening and the wooden cabinet 32.

The present invention is structured so that the dome speaker can be easily fixed to the root
provided on the side of the wooden cabinet, and vibration of the vibration due to sound leakage
or sound from the gap in the front of the wooden cabinet Will not occur.
[0005]
[Means for Solving the Problems] The root case is attached to the side of the wooden cabinet for
fixing the dome speaker by sandwiching the upper and lower sides of the dome speaker, and the
molded support for the dome speaker is inserted from the front of the wooden cabinet.
[0006]
By inserting the dome speaker support molded product from the front of the wooden cabinet, the
molded product is fitted into the opening window of the cabinet, so the gap with the dome
speaker is eliminated, and the occurrence of sound leakage and chatter can be eliminated.
Further, since the opening of the molded product is expanded, the directivity of sound is also
improved, and the acoustic characteristics are improved.
[0007]
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a dome speaker
mounting apparatus according to an embodiment of the present invention; FIG.
In FIGS. 1 to 4, the corresponding parts are denoted by the same reference numerals, and the
detailed description thereof is omitted.
[0008]
In FIG. 1 and FIG. 2 showing the first embodiment of the present invention, 11 is a dome speaker,
12 is a wooden cabinet, 13 is a screen, 15 is a speaker, 16 is a support for a dome speaker, and
17 is a screw.

The operation of the dome speaker mounting apparatus configured as described above will be
described below with reference to FIGS. 1 and 2.
[0010]
In FIGS. 1 and 2, the dome speaker support molded product 16 is inserted into the opening of the
wooden cabinet 12, and the screw 17 is passed through the screw fixing hole 18 and fixed.
On the other hand, the dome speaker 11 is fixed to the side of the wooden cabinet 12 and
inserted into the fitting portion of the dome speaker support molded product 16 at the same
time.
[0011]
In addition, you may comprise so that the opening part of the support molded article 16 for
dome speakers may expand at an obtuse angle as what was mentioned above.
Alternatively, the dome speaker may be attached to the wooden cabinet first, and then the dome
speaker support molding may be attached.
[0012]
FIG. 2 shows an external view of a dome speaker support molding. Next, in FIGS. 3 and 4 showing
a second embodiment of the present invention, the flat dome speaker 21 having the mounting
portion 28 is disposed on the side surface of the wooden cabinet 22, and the screw 27 is used.
[0013]
As described above, according to the present embodiment, it is possible to insert the dome
speaker support molded product from the front of the wooden cabinet and prevent the

occurrence of sound leakage and chatter without bonding the sponge around it. In addition,
installation of the dome speaker to the wooden cabinet is also facilitated.
[0014]
As described above, according to the dome speaker mounting device of the present invention, the
dome speaker is mounted on the side of the wooden cabinet, and the support for the dome
speaker is prevented so that sound leakage and chattering noise are not generated from the front
of the wooden cabinet. By inserting the molded product, the effect of reducing the number of
steps for attaching the dome speaker and improving the acoustic characteristics can be obtained
without using a sponge for preventing sound leakage and chattering noise.
[0015]
In addition, since the dome speaker mounting portion is provided, mounting to the side of the
wooden cabinet is facilitated.
