ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a display, and more particularly, to a device for mounting a speaker on a display.
2. Background of the Related Art
Presently, speaker of built-in or exterior mounting type is provided to a display, to form a multimedia.
FIG. 1
illustrates a perspective view of a related art device for mounting a speaker on a display,
FIG. 2
illustrates a section across line I—I in
FIG. 1
, and
FIG. 3
illustrates a section across line II—II in
FIG. 1
, referring to which the related art device for mounting an exterior speaker on a display will be explained. There are a Braun tube
30
and a cabinet
20
fastened to a front surface of a back cover
10
, and a speaker
40
mounted on a side of the back cover
10
.
This will be explained in detail.
There are bosses
26
on an inside surface of a front portion of a cabinet
20
, and projections, i.e., lugs
32
on outside of the Braun tube
30
for fastening to the bosses
26
with screws
34
. And, there are ribs
22
on inside of sides of the cabinet
20
for fastening the back cover
10
, and a front portion of the back cover
10
has projection, to form a coupling portion
12
to be brought into contact with the ribs
22
. There may be a gap ‘A’ between the cabinet
20
and the back cover
10
caused by a difference of dimensions of the ribs
22
on the cabinet
20
and the coupling portion
12
of the back cover
10
. In the meantime, portions of the coupling portion
12
of the back cover
10
are cut away, to form cut-away portions
14
. A portion of each of the cut away portions
14
exposed through the gap ‘A’ acts as a hole
16
for mounting the speaker
40
. By inserting and fastening holding projections
44
in one side of the speaker
40
to the holes
16
, the speaker
40
can be fastened to the display. The holding projections
44
may be either fabricated separately and fitted to the speaker
40
, or formed as a unit with the speaker
40
.
A process for fastening the speaker
40
to the display will be explained, with reference to FIG.
2
.
First, the holding projections
44
on the speaker
40
are inserted into respective holes
16
in the back cover
10
in a horizontal direction through the gap ‘A’ formed in the coupled portion of the cabinet
20
and the back cover
10
. Then, the holding projections
44
are pushed down so that recesses
46
in the holding projections
44
are caught by the holes
16
, thereby completing mounting of the speaker
40
to the display. However, the aforementioned device for mounting a speaker to a display does not attenuate vibration generated in the speaker
40
, but transmits to the Braun tube
30
directly, to vibrate the Braun tube
30
, seriously. Because the vibration generated during operation of the speaker
40
is transmitted to the back cover
10
through the holding projections
44
on the speaker
40
, and the vibration transmitted to the cabinet
20
is transmitted to the Braun tube
30
through a contact surface between the cabinet
20
and the Braun tube
30
, at last. As explained, since the vibration generated in the speaker
40
is transmitted in succession through a contact surface between solid state bodies, the vibration is transmitted to the Braun tube
30
directly without any attenuation, and the vibration transmitted to the Braun tube
30
resonate with the shadow mask mounted on an inside of the Braun tube
30
, to cause flickering of an image. And, this problem impedes an increase of wattage of the speaker. Particularly, since the flickering of image is the most serious at a frequency below 200 Hz, mounting of a high quality speaker on the display has been very difficult actually because deterioration of sound quality is resulted in as lowering of a low sound band is not possible.
SUMMARY OF THE INVENTION
Accordingly, the present invention is directed to a device for mounting a speaker on a display that substantially obviates one or more of the problems due to limitations and disadvantages of the related art.
An object of the present invention is to provide a device for mounting a speaker on a display, which can prevent an image flickering.
Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims hereof as well as the appended drawings.
To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described, the device for mounting a speaker on a display having a back cover and a cabinet mounted on a front of the back cover includes a plurality of bosses formed on an inside surface of the cabinet, vibration attenuation means coupled to the bosses, and holding projections on the speaker fixed to the vibration attenuation means, thereby, attenuating vibration from the speaker by the vibration attenuation means.
The vibration attenuation means includes a supporting member, and a vibration attenuation member coupled to the supporting member for preventing direct contact of the supporting member to the bosses.
The supporting member has coupling recesses for fixing the holding projections on the speaker after passing through the holes in front portion of the back cover.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
