Description of the Related Art As shown in FIG. 13, for example, a speaker system installed in a display device typified by a television receiver is housed on the left and right sides of a display device (CRT 54) of a television receiver 51. As described above, a vertically long speaker system 52 that is long in the vertical direction of the screen may be used. The reason for this is that with the widespread use of wide televisions having a horizontally long screen (aspect ratio 16: 9), the width Wt of the wide television is suppressed to be compact.

In this case, as shown in FIG. 14, a speaker system 52 having a configuration in which a speaker unit 56, which is an oval or elliptical sound output source, is attached to a vertically long speaker cabinet 57, is used as a television system. The main body 51 is provided between the side wall 53 a of the front frame 53 and the cathode ray tube 54. In FIG. 14, reference numeral 57a denotes a baffle, and an opening 61 for attaching the speaker unit 56 is formed in the center of the baffle. Above and below the opening 61, there are provided bass reflex ports 60 for strengthening the bass range of the sound. The speaker cabinet 57 forms a hollow box body, and a pair of side plates 57d and 57e arranged to face each other in the horizontal direction of the screen.
And a top plate 57b and a bottom plate 57c which are arranged to face each other in the vertical direction of the screen and are respectively connected to upper and lower ends of the side plates 57d and 57e in the vertical direction.
And a back plate 58 connected to an end of the frame constituted by the plate 57b and the bottom plate 57c on the opposite side to the side to which the baffle is connected. The projections 59 formed on the top plate 57b and the bottom plate 57c are connected to the television receiver 5
This is a component for attaching the speaker system 52 to the main body of the main body.

The top plate 8b and the bottom plate 8c are arranged to face each other in the vertical direction of the screen, are connected to a pair of side plates 8d and 8e arranged to face each other in the horizontal direction of the screen, and are different from those described above. A frame is formed. And behind this frame (rear side of the television receiver 1)
A back plate 8a is connected to the end. A baffle 7a of the front speaker cabinet 7 is provided at the front end.
Are connected to the other end that is not connected. Like the front speaker cabinet, the rear speaker cabinet 8 is formed longer in the screen horizontal direction than in the screen vertical direction and extends in the depth direction of the display device. Has a rectangular shape.

In the speaker system 2, the speaker unit 6 is previously mounted on the baffle 7a of the cabinet 7 with a plurality of screws, and then the rear cabinet 8 is mounted on the front cabinet 7 with a plurality of screws and assembled. Television 1
After the cathode ray tube 4 is attached to the front frame 3 of the main body casing, a plurality of projections 9 integrally formed on the side plates 7d and 7e of the front cabinet 7 of the pre-assembled speaker system 2
At a predetermined position of the bottom plate 3a of the front frame 3 of the main body housing with a plurality of screws. Then, an electronic circuit board (not shown in FIG. 1) is attached, and the back cover 5 of the main body housing is mounted on the front frame 3 of the main body housing with a plurality of screws and assembled. In FIG. 2, the bass reflex port 11 is provided on the left side (inside as the television 1 receiver) of the baffle 7a, but may be provided on the right side (outside).

A projection 9 provided on the front cabinet 7 of the speaker system 2 for mounting on the main body of the television receiver 1 has a speaker 9 composed of the front cabinet 7, the rear cabinet 8 and the speaker unit 6. -It is provided on the balance point (on the balance line) of the mass in the front-back direction of the power system 2, that is, on the line including the center of gravity of the speaker system 2 (parallel to the horizontal direction of the screen). This makes it difficult for the vibration generated in the speaker system 2 to be transmitted to the cathode ray tube 4 attached to the main body housing of the television 1, so that the shadow mask of the cathode ray tube does not vibrate and color unevenness hardly occurs. is there.

FIG. 3 is a plan view of a cross section orthogonal to the screen vertical direction of the television receiver according to the present invention shown in FIG. However, in order to increase the internal volume of the speaker cabinet, it is necessary to increase the depth of the speaker cabinet. As a result, the dimension Wr of the rear surface of the television 1 becomes large, and the space for installing the television receiver 1 at the four corners of the room is deteriorated.

Therefore, as shown in FIG.
The rear part of the back cover 5 of the main body housing may be 45 degrees so as to increase the inner volume of the rear part 2 and to facilitate installation of the television 1 in the four corners of the room. The rear of the rear cabinet 12
The front frame 3 is shaped so as to form an angle of 45 degrees with the side wall 3. This makes it easier to take up installation space.

The speaker system 2 shown in FIG. 2 has a flat shape structure as a whole. Therefore, the standing wave and the material and shape of the cabinet 7 are changed by the sound pressure radiated to the rear surface of the speaker unit 6. The structure causes an inherent resonance. As a result, a peak, a dip, and a distorted sound are generated on the reproduced sound pressure frequency characteristic. To suppress this, the front cabinet 7 and the rear cabinet 8
It is sufficient to provide one or a plurality of reinforcing bars connecting the top plates 7b, 8b and 7c, 8c each having a large area. This will be described with reference to FIGS.

As shown in the plan sectional view of FIG. 5, one or a plurality of reinforcing bars are connected so that the top plate 7b, the bottom plate 7c of the front cabinet 7 and the top plate 8b and the bottom plate 8c of the rear cabinet are connected to each other. 7f and 8f are integrally formed and provided. In the front cabinet 7 shown in FIG.
The bass reflex port 11 is formed as a square tube by a partition 7g also serving as a reinforcing bar, a top plate 7b, a bottom plate 7c, and a side plate 7d, but may be a circular tube.

The shape of the bass reflex port 10 shown in FIG. 5 is a simple square tube. Similarly, the reinforcing bar 7f is also a simple plate. This is because the molding die of the cabinet 7 has been considered so that it can be constituted by the simplest upper and lower dies (front and rear dies). Similarly, in the structure of the front cabinet 7 having the configuration shown in FIG. 5, the front cabinet 7 has an opening 10 in the baffle 7a and the rear surface of the front cabinet 7 mounts the rear cabinet 8 as shown in FIG. For this reason, the reinforcing bar 7f is easy to configure. If a molding die using a slide core is used, a more complicated configuration can be achieved.

The reinforcing bars 7f of the front cabinet 7 having the configuration shown in FIGS. 5 and 6 may be non-parallel to the reinforcing bars 7f 'and the side plates 7d and 7e as shown in FIG.

Further, the front cabinet 7 and the rear cabinet 8 having the configuration shown in FIGS.
In this structure, the cabinet 7 is strengthened and the vibration of the cabinet is suppressed. However, since the speaker cabinet is flat and the depth dimension Ds is large, a standing wave is generated, and as shown in FIG. Dip and peak are generated on characteristic a. Therefore, as shown in FIGS. 5 and 6, the sound absorbing material 13 is inserted into a position approximately half the depth Ds of the speaker cabinet. By inserting the sound absorbing material 13, a smooth sound pressure frequency characteristic b without dips and peaks can be obtained as shown in FIG. As a result, there is an effect that a clear reproduced sound without distortion can be obtained.

Next, an example of an embodiment of the present invention regarding a cabinet configuration of the speaker system in consideration of attachment of the speaker system to the main body of the television receiver 1 will be described.

FIGS. 9 and 10 are a plan view and a cross-sectional view as viewed from the side, showing the embodiment. Main electronic circuit board 14
Uses a printed circuit board having a relatively large area of about 1 to 1.5 mm in thickness, but three or four sides are supported by a frame 15 to prevent breakage (3 in FIG. 9).
Side). 9 and 10, the main electronic circuit board 14 held around the frame 15 is inserted into the gap between the cathode ray tube 4 and the speaker system 12 '. Television 1
Below the cathode ray tube 4 of the main body of the receiver, there are a remote control receiving section, a main power button, and a manual control panel 16. It is not preferable that the height Hc of the control panel 16 be increased in design.

Since the frame 15 for holding the main electronic circuit board 14 has a thickness of about 10 mm, in order to suppress the height Hc of the control panel 16 in FIG. 10, the cabinet of the speaker system as shown in FIG. Is cut off by the thickness of the frame 15 (the height of the cabinet is reduced).

Since the speaker cabinet shown in FIG. 11 is configured to be mounted on the right side, a symmetrical mold for the left side is required. Therefore, as shown in FIG. 12, if the top plate and the bottom plate are formed in such a shape as to be cut off, and left and right are reversed and attached, the cost of one molding die can be reduced.

In the description of the present embodiment, a television receiver has been described as an example of a display device. However, the present invention is not limited to this, and the present invention is not limited to a personal computer or a workstation such as a workstation. It goes without saying that the present invention is also applied to a display used as a monitor. Further, in the description of the present embodiment, the configuration in which the speaker system 2 is installed below the cathode ray tube 4 has been described as an example, but the speaker system 2 may be installed above the cathode ray tube. Furthermore, although a cathode ray tube has been described as an example of a display device, it goes without saying that the present invention is similarly applied to a display device using another display device such as a PDP or a liquid crystal panel.

[0034]

As described above, according to the present invention, the width of the display device can be reduced. In addition, when the top plate and the bottom plate of the speaker cabinet are connected by a plurality of reinforcing bars, a strong cabinet structure is obtained, vibration of the cabinet is suppressed, and a clear reproduced sound without any abnormal sound is obtained.

Further, a projection for attachment to the display device is provided on a balance point (on a balance line) of the mass in the front-rear direction of the speaker system, that is, on a line including the center of gravity, and the projection is attached to a television main body housing. This makes it difficult for vibration to be transmitted to the cathode ray tube, and does not cause vibration of the shadow mask, which has the effect of eliminating color unevenness.
