[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker device of a television receiver.
[0002]
2. Description of the Related Art In recent years, in a speaker device of a television receiver, a
speaker is attached by a screw to a cone-shaped speaker aperture boss portion provided in a
cabinet.
[0003]
A conventional speaker device will be described below with reference to FIG. 5 (a).
51 is a cabinet main body for attaching a speaker, 52 is a cone type speaker, 53 is a speaker
panel. The television receiver speaker apparatus configured as described above will be described.
[0004]

However, in the configuration as described above, since the cone-shaped speaker 52 is directly
attached to the cabinet body 51, the diaphragm of the cone-shaped speaker 52 is in contact with
the front surface of the cabinet body, Moreover, since the cone-shaped speaker aperture is large
and the reinforcing rib is provided on the cabinet body, good sound reproduction can not be
obtained.
SUMMARY OF THE INVENTION In view of the above problems, the present invention provides a
television receiver and speaker apparatus which can reproduce good sound while saving a space
in a cone-shaped speaker opening.
[0006]
SUMMARY OF THE INVENTION In order to solve the above problems, the speaker device of the
television receiver according to the present invention is provided with a dome-shaped molded
article having a cone-shaped speaker mounted on the bottom of the cabinet body. . In addition, a
chassis rail integrated dome-shaped molded product is attached to the bottom of the cabinet
body.
[0007]
With the above-described configuration, the present invention enables space saving of the
speaker attaching device portion on the front surface of the cabinet body, and the cabinet
opening ratio of the speaker becomes larger than that of the prior art by the reinforcing rib and
good sound without distortion. It is possible to realize the regeneration and to improve it
significantly. Further, the chassis rail integral type can reduce the number of mounting steps.
[0008]
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A loudspeaker apparatus of a
television receiver according to an embodiment of the present invention will be described with
reference to the drawings.

[0009]
In FIG. 1 showing the first embodiment, 11 is a cabinet body, 12 is a cone-shaped speaker, 14 is
a dome-shaped molded article, and 15 is a sound absorbing material.
[0010]
The operation of the television receiver speaker apparatus configured as described above will be
described below.
[0011]
By attaching the cone-shaped speaker 12 and the sound absorbing material 15 to the inside of
the dome-shaped molded product 14 and fixing them to the ribs of the cabinet main body 11, the
front of the cabinet becomes compact, so the reinforcing rib of the speaker opening is
unnecessary It is possible to obtain excellent acoustic characteristics without distortion.
[0012]
Next, a second embodiment will be described with reference to FIG.
In FIG. 2, a dome-shaped wall 24 is provided so that the cone-shaped speaker 22 can be attached
to the bottom of the cabinet body 21, and the cone-shaped speaker 22 is fixed thereto.
The lid 27 is slid along the groove on the bottom side of the dome-shaped wall 24 of the cabinet
body 21 and fixed with screws.
Since the speaker panel 23 is inserted into the front of the cabinet body 21 and the front of the
cabinet becomes compact, excellent acoustic characteristics without distortion can be obtained.
[0013]
Next, a third embodiment will be described with reference to FIG.

In FIG. 3, a dome-shaped speaker attachment molded product 34 is provided on the back cover
main body 39, and a cone-shaped speaker 32 is attached to the attachment cover 38 here. There
is a hole in the cabinet 31 into which the dome-shaped speaker attachment molded part 34 is
inserted, and the hole is fitted into this hole.
[0014]
A fourth embodiment will now be described with reference to FIG. In FIG. 4, the dome-shaped
speaker attachment molded product 44 integrally formed with the chassis rail 40 so as to be
attached to the cabinet main body 41 is provided, and when the chassis rail 40 is inserted into
the cabinet main body 41 It is a thing.
[0015]
As described above, according to the speaker device of the television receiver of the present
invention, the cone-shaped speaker and the sound absorbing material are attached to the domeshaped molded product and fixed to the speaker portion at the bottom of the cabinet body. It is
possible to obtain reproduced sound with good sound quality without distortion. Further,
according to the present invention, it is possible to save space in the height direction of the
speaker attaching device portion on the front surface of the cabinet body, and a compact
television receiver set can be obtained.
