DESCRIPTION JPH02312393
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
speaker apparatus for television, and more particularly to an improvement of a speaker box
provided in parallel in a television cabinet. [Prior Art] FIG. 3 and FIG. 4 are plan views of a
conventional speaker apparatus for television, and in FIG. 1 (1) is a television cabinet, and (2g) is
juxtaposed on both left and right side surfaces of this television cabinet. Speaker box, (3a) is a
speaker unit provided in the speaker box for reproducing the entire band, (7) is a back wall of the
television cabinet, (8) is furniture in a room, and the speaker boxes (2a) are Side by side. In the
conventional speaker apparatus for television, as shown in FIG. 3, the speaker box (2a) is
integrally attached to the left and right rear sides of the television cabinet (1). In this case, the
furniture (8) is adjacent The sound field is disturbed due to the influence of the noise, and even
when not adjacent to each other, there is a problem that acoustic characteristics such as sound
image localization deteriorate due to the directivity of each speaker unit depending on the
viewing position. Furthermore, in the case of the side-by-side arrangement shown in FIG. 4, the
speaker box (2a) travels to the left and right of the television cabinet (1) although there is no
effect of adjacent furniture, and there is a problem in space saving. . [Problems to be Solved by
the Invention] Since the conventional speaker apparatus for television is configured as described
above, there is a problem that acoustic characteristics such as sound image localization
deteriorate depending on the installation condition and the viewing position of the television. In
the improved version, the speaker box went from the TV cabinet to the left and right, and there
was a problem in space saving. The present invention has been made to solve the abovementioned problems of the prior art, and the sound performance such as sound image
localization is also deteriorated depending on the viewing position and the installation condition
of the television without the speaker box traveling from the television cabinet It is an object of
the present invention to obtain a television speaker device which has no problem. [Means for

1
Solving the Problems] The speaker apparatus for a television according to the present invention
has a special shape in which the rear portion of a speaker box juxtaposed to a television cabinet
is broadened using a rear narrowing portion of the television cabinet. A bass speaker unit is
provided in the rear enlarged space, a middle to high tone speaker unit is provided in the narrow
front narrowing space, and the above bass speaker is disposed above and below the middle to
high speaker unit. A sound V-tube is attached to pass only the bass emitted from the unit.
[In the speaker apparatus of the present invention, the rear narrowing portion of the television
cabinet is used to form the rear expansion space of the speaker box accommodating the bass
speaker unit, and the front of the narrow speaker box is Only the bass from the bass speaker unit
is radiated from the acoustic tube which is used for the housing space of the high-pitched
speaker unit and further provided on the front side of the television cabinet. An embodiment of
the present invention will be described below. That is, in FIG. 1 and FIG. 2, (1) is a television
cabinet, (2) is a speaker box of the present invention juxtaposed on the left and right sides
thereof, and these speaker boxes (2) A speaker unit (3) with a diameter of 10 cm is attached
within the rear expansion space (A) which is formed wide using the rear narrowing portion (la) of
1), and is more In the front sandwiching space (B) formed narrow inside, an elliptical medium-tohigh-tone speaker unit (4) with a diameter of 4.5 cm x 10 cm is attached The upper and lower
sides of the speaker unit (4) are characterized in that they are each provided with an acoustic
tube (5) narrower than this and passing only the low frequency sound radiated from the low
frequency speaker unit (3). . In the other figures, (6) is a sound absorbing material provided in
the rear enlarged space (A). Specifically, for the front width of the speaker box (2) of the present
invention, the bass speaker unit (3) with a diameter of 10 cm uses the rear narrowing portion
(1a) of the television cabinet (1) As it can be accommodated in the enlarged space (A), it is
determined by the width (diameter) of the medium / high-tone speaker unit (4) to be installed as
a result. That is, in the case of an elliptical speaker unit for medium and high sound with a
diameter of 4.5 am × 10 cm used in this embodiment, the front width of the speaker box (2) is 5
cm and 5 cm. This is a conventional television speaker apparatus, which requires a 10 cm
aperture speaker unit to obtain the same acoustic performance as this embodiment, and the front
width of the speaker box at this time is 11, 5c + 1. A speaker box of 172 or less in slim
appearance will be obtained. The middle and high tones are emitted from the center of the front
of the speaker box and the low tones from the low frequency speaker unit (3) are emitted from
the acoustic tube (5) of the opening 111g4.5cO1 provided on the front of the speaker box. There
is no problem in acoustic performance, and furthermore, stable performance is obtained without
deterioration of sound image localization due to the viewing position as well as deterioration of
sound due to furniture, walls, etc. arranged in parallel.
Furthermore, since the sound from the bass speaker unit passes through the acoustic tube, the
high range is attenuated, and the bypass filter (network circuit) can be omitted. [Effects of the

2
Invention] Since the speaker apparatus for television of the present invention is configured as
described above, stable acoustic performance is obtained without being affected by the viewing
position and the installation conditions of the television, and the appearance is slim. There is an
effect that a television speaker device can be obtained which saves space.
