Description

  The present invention includes a panel-like device body that is provided with a video display unit on the front side and a speaker on the back side, and that can reproduce video and sound recorded on an information recording medium, and that the device body is supported in an upright state. In particular, the video display device includes a stand for displaying the image by guiding the sound of a speaker arranged on the back side of the device body from the back side of the device body to the front side of the device body through a sound path. The acoustic performance of the apparatus is improved.

A stand shown in FIG. 11 is known as a stand for raising a panel such as a photograph. The stand 101 is inclined with respect to the sheet-like substrate 102 via a sheet-like substrate 102 having shape retention and a first bending portion 104 provided along one end edge 103 of the sheet-like substrate 102. An inclined support formed by a holding piece 106 bonded to the back surface 105a of the panel 105 and a second bending portion 107 in a direction orthogonal to the holding piece 106 and inclined at a predetermined angle with respect to the sheet-like substrate 102. Bends according to the inclination of the inclined support leg 108 via the leg 108 and a third bending portion 109 provided on the free end side of the inclined support leg 108 and is bonded to the back surface 105a of the panel 105 to form the inclination A positioning piece 110 for positioning the support leg 108 with respect to the panel 105, and a stand for standing the panel 105 to which a photograph or the like is attached. It has been used Te. (For example, Patent Document 1)
By the way, in recent years, a panel-like video display device generally called a photo stand for reproducing video and sound recorded on an information recording medium such as a memory card has been developed. As shown in FIG. 12, the video display device 201 includes a video display unit 202 on the front side and a speaker 203 on the back side, and plays back video and sound recorded on an information recording medium 204 such as a memory card. Is supposed to do. The speaker 203 is arranged on the rear side of the panel-like video display device 201. If the speaker 203 is arranged on the front side, the width of the frame 205 of the video display unit 202 has to be increased, and that panel-like video display device is more likely to be provided. This is because 201 becomes large or the video display unit 202 is narrowed.

On the other hand, as the stand of the panel-like video display device, for example, a stand 302 of the external storage device 301 as shown in FIG. 13 is used. As shown in FIG. 14, the stand 302 of the external storage device 301 includes a device placement surface 303 on which the external storage device 301 is placed, device sandwiching surfaces 304 and 305 that sandwich the external storage device 301, and leg portions. 306, and a pair of left and right stand components 307, 308 can be moved in the direction of approaching or separating from the pair of device clamping surfaces 303, 304 by means of long groove-shaped screw receiving grooves 309, 310 and screws 311, 312. The external storage device 301 is held between the pair of device holding surfaces 303 and 304 and held in an upright state. (For example, Patent Document 2)
Japanese Utility Model Publication No. 06-000214 Japanese Patent Application Laid-Open No. 05-266643

  By the way, the stand 302 of the external storage device is provided with a video display unit 202 such as a liquid crystal on the front side, a speaker 203 is provided on the back side, and video and sound recorded on an information recording medium 204 such as a memory card are reproduced. When used as a stand of a panel-like video display device 201 that is designed to be used, the panel-like video display device 201 has a speaker 203 provided on the back side. Is propagated exclusively to the back side of the panel-like video display device 201 and hardly propagates to the front side of the panel-like video display device 201. In particular, the high frequency range component with high directivity is impaired, so that there is a problem that the sound becomes so-called.

  The problem can be solved by arranging the speaker 203 in the outer frame 205 of the video display unit 202 on the front side of the panel-like video display device 201. However, the speaker 203 is arranged in the frame 205. For this purpose, the width of the frame 205 must be increased. Since the unit of the speaker 203 has a size of about φ20 mm at the minimum, in order to arrange the unit of the speaker 203 on the frame 205, the width of the frame 205 must be further increased. If the frame 205 is widened, the panel-like image display device 201 becomes large. Further, if the frame 205 is expanded without changing the size of the panel-like video display device 201, the video display unit 202 is probably downsized.
