Description

  The present invention relates to a video display device, and more specifically, a personal computer (hereinafter abbreviated as a personal computer) having a thin display unit such as a liquid crystal display device (LCD) or a plasma display device (PDP), or a television receiver. The present invention relates to a video display device applied to the above.

  In recent years, electronic devices have been reduced in size and thickness due to development of electronic technology and increasing user needs. In order to reduce the thickness of television receivers, liquid crystal televisions using liquid crystals, plasma televisions using plasma emission, and the like have been introduced into the market, from those using cathode ray tubes. A television receiver has a function of outputting an image and sound, and a speaker is generally used for outputting sound.

  Examples of the structure of a speaker portion of a typical conventional television receiver are known as shown in FIGS. 1 and 2 (see, for example, Patent Document 1 below). FIG. 1 (A) is a perspective view of a main part showing an example of a configuration using a speaker box for a speaker mounting portion, and FIG. 1 (B) is a configuration in which a speaker alone is directly attached to a cabinet of a television receiver. It is a principal part perspective block diagram which shows an example.

  In the configuration example of FIG. 1A, a television receiver 101 is roughly configured by a front cabinet 102, a display 103 such as a cathode ray tube, and a rear cover 104. A speaker box 107 to which a speaker 106 is attached is attached to the front cabinet 102 with a screw 109 via a vibration isolating material 108. Sound generated from the speaker 106 is diffused to the front surface of the television receiver 101 through a vent hole (not shown) provided in the front cabinet 102.

  In the configuration example of FIG. 1B, a speaker 106 is attached to the front cabinet 102 of the television receiver 101 with a screw 109 via a vibration isolator 108. The sound generated from the speaker 106 is diffused to the front surface of the television receiver 101 through a vent hole (not shown) provided in the front cabinet 102 as in FIG.

  FIG. 2 is a perspective view of a main part showing another configuration example of a conventional television receiver. According to the configuration of FIG. 2, the bent portion of the speaker box 107 bent in an L shape is arranged between the display 103 and the rear cover 104, so that the television receiver can be made thin and high-quality sound can be obtained. Can be output.

  FIG. 3 is a schematic plan view showing still another configuration example of a conventional television receiver. A pair of middle and high frequency range speakers 111 are provided on the front of the television receiver 110 on the left and right sides. By providing one low-frequency speaker 112 on the back, the sound field expansion effect can be increased (for example, see Patent Document 2 below). In this case, as shown in FIG. 3, the mid-high range sound output from the left and right mid-high range speakers 111 reaches the listener 120 directly via the path D. The low frequency range sound output from the low frequency range speaker 112 is reflected by the rear wall surface 113 and the side walls 114 and 115 along the path R and reaches the listener 120, and the right and left side surfaces 110 a of the television receiver 110 are transmitted along the path T. , 110b reaches the listener 120 as a diffracted sound along the line 110b. Thereby, the sound field can be sufficiently expanded without increasing the width of the television receiver 110.

  FIG. 4 is a diagram showing still another configuration example of a conventional television receiver. The speaker device of the television receiver includes a speaker 138, a sound conduit 137 disposed on the front side of the speaker 138, and a rear surface of the speaker 138. And a woofer box 131 disposed on the side, and a port 140 of the woofer box 131 is formed downward. The television receiver is composed of a CRT 134, a control circuit board 135 and a cabinet 132 for housing the speaker device, and a back cover 133. On the front side of the cabinet 132, a sound emission hole 139 corresponding to the sound conduit 137 is provided. An opening 136 corresponding to the port 140 is provided on the bottom surface side, and sounds are emitted from the bottom surface of the cabinet 132 to enhance the bass (for example, see Patent Document 3 below).

  In a television receiver, a large-diameter speaker is required to reproduce the necessary low-frequency sound, and when a large-diameter speaker is used, two more tweeters are required for medium-high sound range reproduction. On the other hand, in the recent television receiver, the occupied area given to the speaker is very small from the viewpoint of emphasizing the design. For this reason, a small-diameter speaker is used and sacrifices low-frequency reproduction.

In addition, in the conventional television receiver, the thinned television receiver as shown in FIG. 1A cannot accommodate the speaker box, or the speaker box itself is limited in volume because it is limited by the depth of the television receiver. However, there was a problem that the sound quality was lowered. Further, since the television receiver as shown in FIG. 1B does not have a built-in speaker box, there is a problem in that it has a low dynamic range and is difficult to apply to a high-quality television receiver. Further, the television receiver shown in FIG. 4 is a cathode ray tube type television receiver, and the characteristics of the back speaker for the low sound range are not sufficiently exhibited in the case of wall hanging using a liquid crystal television or the like.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 5A and 5B are diagrams illustrating a television receiver according to an embodiment of the present invention. FIG. 5A is a front view, FIG. 5B is a right side view, and FIG. The television receiver 10 includes a display main body 1 using a thin display device 2 such as a liquid crystal display (LCD) or a plasma display device (PDP) as a display unit. A pair of middle and high range speakers 4a and 4b to be reproduced and a low range speaker (woofer) 3 for reproducing a low range disposed between the pair of middle and high range speakers 4a and 4b. is doing.

  The stand 8 includes a stand column 5, a stand bottom body 6, and a handle portion 7, and also serves as a handle by the handle portion 7 provided on the upper portion. The back surface of the stand 8 and the display main body 1 is screwed to the top of the stand 8 with screws 9 so that the stand 8 and the display main body 1 can be attached and detached. Thereby, two types of usage forms of a stand type and a wall hanging type can be selected, and high convenience is provided to the user.

  Next, in the first embodiment shown in FIG. 5, a speaker (woofer) 3 for reproducing a low frequency range will be described in detail with reference to FIGS. 6 is a schematic view of the inside of the display main body 1 of FIG. 5 as viewed from the back side. In FIG. 6, 4a and 4b are loudspeakers for middle and high sounds, 11 is a loudspeaker (woofer) box, and 12 is a duct outlet (sound outlet).

  FIGS. 7 and 8 are diagrams for explaining the internal structure of the speaker box 11 and the duct outlet 12 shown in FIG. 6. FIG. A perspective external view of the speaker box 11 is shown in FIG.

  The low sound range speaker (woofer) box 11 is characterized in that a duct 13 having an elliptical cross section is provided therein. The low sound range speaker box 11 is improved in bass characteristics as the cross section of the duct 13 is increased and the length thereof is increased. However, since it is desired to make the display main body 1 of the television receiver as thin as possible, it is necessary to reduce the size and thickness of the low-frequency speaker box 11 as well. For this purpose, the cross-section of the duct 13 of the speaker box 11 for low-frequency range is made elliptical, and the short axis direction of the ellipse is made to coincide with the thickness direction of the display main body 1 to reduce the thickness of the display main body 1. Yes. Further, when the duct 13 has a quadrangular cross section, sound stagnation occurs.

  Further, in order to improve the bass characteristic by making the length of the duct 13 as long as possible, the duct 13 is installed so as to be inclined in the speaker box 11 for bass. Since the outlet (sound outlet) 12 is disposed so as to face downward of the television receiver, the duct 13 is bent in the vicinity of the outlet 12.

  Further, the end face of the duct tip 12a in the discharge port 12 portion is obliquely (tapered) so that a taper is formed in the radial direction. Moreover, you may make the diameter of the discharge port 12 larger than a duct diameter. With the above configuration, sufficient bass characteristics can be obtained even with a small volume and small diameter unit.

  When the television receiver 10 is installed using the stand 8, the floor material to be installed generally differs depending on the location. For example, sound is easily absorbed when the floor is a carpet, but sound is easily reflected when the floor is a metal. That is, the sound is easily affected by the floor material.

  The television receiver 10 of the present invention is configured such that a discharge port 12 of a duct 13 provided in a speaker box 11 for low sound range is directed downward, and the stand bottom body 6 is located directly below the discharge port 12. It is configured as follows. That is, the stand 8 has a portion facing the discharge port 12 of the duct 13. With such a configuration, since the sound emitted from the discharge port 12 is absorbed and reflected by the stand bottom body 6, a stable sound quality can be obtained without being affected by the material of the floor at the installation location.

  Next, a configuration example of a speaker in the television receiver according to the present invention will be described in detail with reference to FIGS. FIG. 9 is a diagram illustrating an example of an installation unit of three speakers provided in a television receiver. A housing such as a cabinet that incorporates three speakers (low-frequency speakers 3, middle-high speakers 4a, 4b). FIG. 9A shows a partially enlarged view of the speaker installation portion viewed from the outside, and FIG. 9B shows a cross-sectional view taken along the line BB of FIG. 9A.

  Similarly, FIGS. 10 and 11 are views showing other examples of the installation portions of the three speakers provided in the television receiver, respectively. FIG. 10 (A) is a partially enlarged view seen from the outside of the housing such as a cabinet. Each figure (B) shows a BB sectional view of each figure (A).

  The display unit main body 1 of the television receiver 10 provided with the thin display device is provided with one low-frequency speaker 3 and two middle and high-frequency speakers 4a and 4b as described above. Is attached to the inside of the cabinet 20 constituting the casing of the display unit main body 1, and is configured to emit sound from the inside toward the outside of the cabinet 20.

  In each embodiment shown in FIG. 9 to FIG. 11, a plurality of through holes 21 are provided in a cabinet region R1 having a shape substantially corresponding to the diameter of the speaker at the mounting portion of each speaker 3, 4a, 4b of the cabinet 20. ing. That is, the outer diameter of the region R1 is substantially equal to the aperture of the speaker. Further, a plurality of non-through holes (blind holes) 22 are provided in a region R2 around the outside of the region R1 in which the through holes 21 are provided. The non-through hole 22 is formed so as to open to the outside of the cabinet 20 (the side normally viewed by the viewer).

Etc. can be applied as appropriate. The maximum dimension of the formation region R2 of the non-through hole 22 is determined according to the strength of the cabinet 20, the relationship with the thin display device 2, and the like. The size of the formation region R2 of the non-through hole 22 is not affected by the size of the formation region R1 of the through hole 21. That is, even if the diameter of the speaker is large, the outer peripheral dimension of the formation region R2 of the non-through hole 22 may be reduced.

  In the configuration of FIG. 11, the low frequency range speaker 3 has a larger diameter than the mid and high range speakers 4a and 4b, and the outer peripheral shape of the formation region R2 of the non-through hole 22 is the same as that of the mid and high range speakers 4a and 4b. The low-frequency speaker 3 has a different shape. In the example of FIG. 11, the outer peripheral shape of the non-through hole 22 formation region R2 corresponding to the mid-high range speaker 4a, 4b is circular, and the non-through hole 22 formation region R2 corresponding to the low range speaker 3 is The outer peripheral shape is a quadrangle.

  With the above configuration, the bass can be enhanced and the loudspeaker can be made larger, so that a high-class feeling can be obtained. In the example of FIG. 11, as in the examples of FIGS. 9 and 10, the outer periphery of the formation region R <b> 1 of each through-hole 21 has substantially the same shape as the shape of each speaker 3, 4 a, 4 b. As the outer peripheral shape of the formation region R2, a circle, an ellipse, a square, a polygon, or the like can be applied as appropriate. The maximum dimension of the formation region R2 of the non-through hole 22 is determined according to the strength of the cabinet 20, the relationship with the thin display device 2, and the like. The size of the formation region R2 of the non-through hole 22 is not affected by the size of the formation region R1 of the through hole 21. That is, even if the diameter of the speaker is large, the outer peripheral dimension of the formation region R2 of the non-through hole 22 may be reduced.
