One end side of the light shielding sheet 70 is led out from the lead-out hole 75 provided on the outer side surface 22 b of the speaker box 22, and is coupled to the coupling member 71 on the back side of the grill net 31.

  As shown in FIG. 22A, the light shielding sheet 70 is always urged into the speaker box 22 by a support spring 73, and the grill net 31 is located at the innermost position of the speaker box 22. Is housed in the speaker box 22. When the grill net 31 is moved to the outside of the outer side surface 22b of the speaker box 22, one end side of the light shielding sheet 70 is pulled by the coupling member 71 as shown in FIG. It is led out from the lead-out hole 75 against the urging force. Thereby, since the light shielding sheet 70 is led out along the back surface of the grill net 31, the back surface side of the grill net 31 can be shielded, and the back surface side of the grill net 31 is transparent when viewed from the front. Can be prevented. Further, since the light shielding sheet 70 has a length corresponding to the moving range of the grill net 31, it is possible to always prevent transmission on the back side regardless of the moving position of the grill net 31.

  Further, the speaker device 1 may use a light shielding plate 80 shown in FIG. 23 instead of the light shielding sheet 70 described above. As shown in FIGS. 24 and 25, the light shielding plate 80 is formed in a substantially U shape, and the upper surface 80a and the lower surface 80b facing each other form a right triangle, and both the oblique sides have a rectangular shape with the upper side and the lower side. It has a side wall 80c. The shielding plate 80 is formed of a thin plate-like material that does not transmit light, such as a sheet metal. On the upper and lower surfaces 80a and 80b of the light shielding plate 80, a pair of upper and lower pivot convex portions 81 and a slide convex portion 82 are erected in the vicinity of one end and the other end of both oblique sides.

  The pivot protrusion 81 is rotatably supported by the grill net 31 and serves as a rotation fulcrum of the light shielding plate 80. The slide convex portion 82 is movably supported by the speaker box 22, and defines a rotation region so that the rear surface of the grill net 31 is always covered by the light shielding plate 80.

  As shown in FIG. 23, in the grill net 31 that supports the pivot protrusion 81, a storage groove 85 that stores the upper and lower surfaces 80a, 80b of the light shielding plate 80 is formed on the outer surface 31a side of the upper and lower side walls 31c, 31d. A pivot recess 86 that supports the pivot projection 81 is provided in the storage groove 85. Therefore, the light shielding plate 80 is rotated around the pivot recess 86.

  In addition, the speaker box 22 that supports the slide protrusion 82 is formed with storage recesses 87 for storing the upper and lower surfaces 80a and 80b of the light shielding plate 80 in the front-rear direction on the upper and lower sides of the outer surface 22b. A slide concave portion 88 that supports the slide convex portion 82 is provided in the 87. The housing recess 87 is a region in which the upper and lower surfaces 80a and 80b of the light shielding plate 80 that rotates with the pivot convex 81 as a fulcrum is stored, and is formed over the rotatable regions of the upper and lower surfaces 80a and 80b. . The slide recess 88 is formed across the speaker box 22 in the front-rear direction, and regulates the sliding direction of the slide protrusion 82 of the light shielding plate 80 to restrict the rotation region of the light shielding plate 80.

  As the grill net 31 moves, the light shielding plate 80 is rotated while the slide convex portion 82 moves back and forth with the pivot convex portion 81 as a fulcrum, so that the rear surface side of the grill net 31 is always placed on the upper and lower surfaces 80a. , 80b and the side wall 80c to prevent transmission on the back side. Specifically, as shown in FIG. 26A, when the grill net 31 is located on the innermost side of the speaker box 22, the light shielding plate 80 has a pivot convex portion 81 in the vicinity of the outer surface 22b of the speaker box 22. Since the slide convex portion 82 is slid to the most back side of the slide concave portion 88, the side wall 80c is made parallel to the side wall of the speaker box 22, and the upper and lower surfaces 80a, 80b are the concave portions for accommodating most of them. 87. Thus, in the speaker device 1, the outer surface 31 a of the grill net 31 and the outer surface 22 b of the speaker box 22 are substantially flush with each other. At this time, the front surface 22a of the speaker box 22 is not covered with the grill net 31 and is exposed to the outside.

  As shown in FIGS. 26B and 26C, when the grill net 31 is slid outward from here, the light shielding plate 80 has the pivot convex portion 81 engaged with the pivot concave portion 86 as the speaker box 22. Accordingly, the slide convex portion 82 is moved forward through the slide concave portion 88. Accordingly, the upper and lower surfaces 80a and 80b of the light shielding plate 80 are slid to the outside from the housing recess 87, and the side wall 80c extends between the outer surface 31a of the grill net 31 and the outer surface 22b of the speaker box 22. It is rotated. As described above, the light shielding plate 80 rotates so as to cover the rear surface of the grill net 31 with the upper and lower surfaces 80a, 80b and the side walls 80c as the grill net 31 moves, and always shields the rear surface of the grill net 31 from light.

  As shown in FIG. 26 (d), when the grill net 31 is moved most outward, the light shielding plate 80 has a part of the upper and lower surfaces 80a and 80b accommodated in the accommodation groove 85 and the slide protrusion 82 is formed. Slide to the front end of the slide recess 88. As a result, the grill net 31 is further restricted from moving outward.

  The light shielding plate 80 has an upper and lower surfaces 80 a and 80 b that are always formed in the grill net 31 even when the grill net 31 is moved to any position between the innermost side and the outermost side of the speaker box 22. 85 or the storage recess 87 of the speaker box 22. Therefore, since the space covered by the upper and lower surfaces 80a, 80b and the side wall 80c is shielded from the outside regardless of the position of the grill net 31, the light shielding plate 80 always has the rear side of the grill net 31 when viewed from the front. It is possible to prevent see-through.

  Further, the speaker device 1 is connected to the speaker box 22 by the upper and lower surfaces 80a and 80b and the side walls 80c of the light shielding plate 80 even when the grill net 31 is moved to the outside of the speaker box 22 from the vertical direction or the back side. The step between the grill nets 31 can be eliminated, and the cavity inside the light shielding plate 80 can be concealed to give a good appearance as if it was designed from the beginning.

  Next, an embodiment in which the speaker box 22 is moved in the width direction of the display device 6 together with the grill net 31 will be described. As shown in FIGS. 27 to 29, the stand 2 of the speaker device 1 has a pair of support plates 90 and 90 that support the speaker unit 3 on both the left and right sides of the player unit 4. The support plates 90 and 90 are provided with the grill net 31 on the front surface 90a side on the same side as the image display surface of the display device 6 and the speaker box 22 on the opposite back surface 90b side. The speaker box 22 is integrally connected via a support plate 90 and is supported so as to be movable in the width direction of the display device 6.

  Thereby, the speaker device 1 to which the present invention is applied slides the speaker box 22 and the grill net 31 in accordance with the width of the display device 6 fastened and supported by the mounting plate 12, thereby providing a uniform appearance design. Is to create. For this reason, the speaker box 22 and the grill net 31 are designed to be slidable in a state where the display device 6 is mounted on the mounting portion 12.

  The support plate 90 is formed on both the left and right sides of the player unit 4 so as to be positioned below the mounting plate 12 formed on the frame 11 and formed in a rectangular shape so that the upper side and the lower side thereof are the player side. The upper side and the lower side of the unit 4 are flush with each other to provide a unified appearance design.

  In addition, guide long holes 91 are formed in the support plate 90 in the vicinity of the upper side and the lower side in the same direction as the width direction of the display device 6. A guide pin 93 protruding from the speaker box 22 and connected to the grill net 31 is inserted into the guide long hole 91, and the guide box 93 is guided to guide the speaker box 22 and the grill net 31 to the support plate 90. It is moved along. In the support plate 90, two guide long holes 91 are formed in parallel in the vicinity of the upper side and the lower side, respectively, and the moving area of the speaker box 22 and the grill net 31 is defined by the length of each guide long hole 91.

  Further, the support plate 90 is formed with an opening 94 between the guide long holes 91 and 91 formed near the upper side and the lower side so that the speaker box 22 faces from the front surface 90a side. The opening 94 is a region opened so as not to block the output from the speaker box 22 supported on the back surface 90 b side of the support plate 90, and is substantially rectangular inward from the outer edge of the support plate 90. Is open. As a result, the support plate 90 allows the speaker arranged in the speaker box 22 to face the front surface 90a side even when the speaker box 22 and the grill net 31 are moved from the innermost position to the outermost position. There is no blocking.

  Further, the support plate 90 is subjected to a surface treatment as an appearance surface on which a front surface 90a that is in the same direction as the image display surface of the display device 6 is visually recognized by the user. Examples of the surface treatment include painting, woodgraining or color film wrapping, embossing, and mirror finishing.

  As shown in FIG. 30, the speaker box 22 and the grill net 31 supported by the support plate 90 are connected by the guide pins 93 protruding from the front surface 22 a of the speaker box 22 engaging the grill net 31. Has been. Further, as described above, the guide pin 93 is inserted through the guide long hole 91 of the support plate 90, so that the speaker box 22 and the grill net 31 are supported on the front surface 90a side and the back surface 90b side via the support plate 90. ing.

  The speaker box 22 and the grill net 31 have their weight transmitted from the guide pin 93 to the support plate 90 and the player unit 4 through the guide long hole 91 when the guide pin 93 is inserted into the guide long hole 91. The player unit 4 is supported by the frame 11 on which the player unit 4 is mounted.

  In the speaker device 1 as described above, as shown in FIGS. 27 and 31A, the speaker box 22 and the grill net 31 are located on the innermost side of the support plate 90, that is, toward the player unit 4 in the width direction of the support plate 90. Even during the movement, a part of the inside of the front surface 90a of the support plate 90 is exposed. Therefore, in the speaker device 1, as shown in FIGS. 28 and 31 (b), the speaker box 22 and the grill net 31 move to the outside of the support plate 90, that is, to the opposite side of the player unit 4 in the width direction of the support plate 90. As a result, the exposed area of the front surface 90a expands outward. Here, as described above, the front surface 90a of the support plate 90 is subjected to surface treatment as an appearance surface visually recognized by the user, and the exposed area expands to the outside as the speaker box 22 and the grill net 31 move. However, since the appearance that was exposed from the beginning has only expanded outward, the appearance design does not give a sense of incongruity, as if the speaker box 22 and the grill net 31 were located outside from the beginning. Can show.

  Therefore, the speaker device 1 moves the speaker box 22 and the grill net 31 in the width direction of the display device 6 even when the width of the display device 6 mounted on the mounting plate 12 is wider than the width of the audio unit 5. As a result, it is possible to create an appearance as a product that is produced according to the width of the display device 6 from the beginning, and to obtain an exterior design with a sense of unity. Therefore, since the speaker device 1 can give a sense of unity regardless of the size of the display device 6, it is possible to select the display device 6 that is owned in advance or the display device 6 that suits the user's preference.

  In the present embodiment, since the speaker box 22 and the grill net 31 move integrally, the phenomenon that the back surface of the grill net 31 does not occur does not occur, and the appearance design is not impaired.

  By the way, in the speaker device 1 in which the speaker box 22 and the grill net 31 are moved together, the speakers 24 to 27 as sound sources move with the movement of the speaker box 22, so that the sound image, the spread of sound, the sound field, and so on. Etc. change. That is, since the speaker unit 3 changes the distance between the left and right speaker boxes 22 as the sound generator by changing the distance between the left and right speaker boxes 22 as the sound generator, the sound image, sound quality, localization, and sound field are left as they are. Etc. will change slightly.

  Therefore, in the speaker device 1, electrical correction is performed using a DSP (Digital Signal Processor) 18. The DSP 18 can correct changes in the sound image, the sound spread, the sound field, and the like accompanying the movement of the speaker box 22. Specifically, a sensor 100 that detects the position of the speaker box 22 as the speaker box 22 moves is provided, and the signal can be corrected to the DSP 18 via the CPU 23 (FIG. 4).

  For example, a detection switch 101 that detects the position of the speaker box 22 can be used as the sensor 100. As shown in FIG. 32, a plurality of detection switches 101 are provided at predetermined positions on the moving area of the speaker box 22, and ON / OFF switching is performed as the speaker box 22 moves. When the thin display device 6 having a specified size is attached, the detection switch 101 is moved when the speaker box 22 moves to each position corresponding to the outer surface of the display device 6 having each specified size. Is placed at a position where it touches and is pressed. These detection switches 101 are monitored for depression by a CPU 23 provided in the player unit 4.

  When the CPU 23 determines the position of the speaker box 22 from the pressed state, the CPU 23 instructs the DSP 18 to perform a correction operation such as a sound image or a sound field according to the determination result. In the correction by the DSP 18, for example, correction data is created in advance so that the sound image, the sound spread, and the sound field are optimized in accordance with the predetermined movement position of the speaker box 22, and automatically based on the correction data. to correct.

  For example, when the display device 6 having a size of 40 inches, 42 inches, or 46 inches is attached, the detection switch 101 is moved when the speaker box 22 is moved to a position (a, b, c) corresponding to each size. The speaker box 22 is disposed so as to be sequentially contacted according to the moving position (a, b, c). Thereby, when the display device 6 having any one of the above sizes is mounted, the speaker box 22 is moved to a position corresponding to the size, and the detection switch 101 is turned ON or OFF depending on the moved position. When the CPU 23 monitors the pressing state of each detection switch 101 and determines the movement position of the speaker box 22, the DSP 18 is instructed to perform correction according to the movement position, and the DSP 18 performs correction based on predetermined correction data. I do.

  The speaker device 1 can also use a rotary encoder 110 as the sensor 100. As shown in FIG. 33, the rotary encoder 110 has a gear 111 attached coaxially. The gear 111 meshes with a rack portion 112 provided in the speaker box 22 and rotates on the rack portion 112 as the speaker box 22 moves. Thereby, the rotary encoder 110 is rotated according to the moving distance of the speaker box 22, and a pulse signal or a pattern signal matching the rotation is output and sent to the CPU 23. The CPU 23 can detect the position of the speaker box 22 based on this signal, and sends audio correction data corresponding to the detected position of the speaker box 22 to the DSP 18. As a result, the DSP 10 can correct the sound field optimally even if the speaker box 22 is at an arbitrary position.

  As mentioned above, although two specific implementation methods of the sensor 100 for detecting the position of the speaker box 22 have been given, there are other methods, and the speaker device 1 to which the present invention is applied adopts other methods. Of course you can.

  In addition to the method of detecting the position of the speaker box 22 using the sensor 100 described above and performing correction by the DSP 18 according to the detected position, the speaker device 1 emits a test signal sound from the speaker, for example. Since the sound is measured by a microphone (not shown) and corrected by the DSP 18 and the moving range of the speaker is limited, correction data (map) is created in advance, and these data are transferred by a manual switch (not shown). A method of selecting and correcting by operating the DSP 18 can also be adopted.

  Further, although the speaker device 1 is provided with the speaker unit 3 at the lower portion of the display device 6, it may be provided at the upper portion of the display device 6 or at the upper and lower portions according to the design. In the speaker device 1, the player unit 4 among the audio units 5 may not be supported by the stand 2, and may be disposed in a separately provided rack or the like. The speaker device 1 is not limited to a disc-shaped recording medium such as a CD or DVD as a sound source, but also music or sound received or downloaded through TV broadcasting, radio broadcasting, the Internet or cable broadcasting, or a personal computer, a digital still camera, a camcorder. Etc. You may make it output the music and audio | voice produced by itself.

  The speaker device 1 may be configured to move only one of the speaker boxes 22 in addition to making the pair of left and right speaker boxes 22 movable.
