  FIG. 5 is an explanatory view showing a state in which the dimensions are changed by the first connecting portion, FIG. 6 is an explanatory view showing a state in which the dimensions are changed by the second connecting portion, and FIG. 7 is a view in which the dimensions are changed by the third connecting portion. It is explanatory drawing which shows the state.

As shown in FIG. 1, the display device configured as described above has speaker devices 2 and 2 juxtaposed on the lower side of the display device body 1 and on both sides.
The speaker device 2 includes a main speaker 2a and a sub speaker 2b. The main speaker 2a temporarily fixes the attachment portions 25, 25 of the holding body 23 by bringing them close to the attachment portions 43, 43 of the cover body 42 and inserts the fitting protrusions 25b into the elastic cylinder 43b. By fitting the positioning protrusion 43c into the positioning hole 25c, the mounting position is accurately determined, and then the male screw inserted through the two insertion holes 25a and 25a is tightened into the screw holes 43a and 43a. The speaker 2a is attached.

  A connector 5 is attached to the sub speaker 2b. As for this connection body 5, when the 2nd member 52 is inserted in the 2nd hole 26a, the rolling element 12 engages with the positioning recessed part 52a, and the 2nd member 52 is attached.

  The first member 51 of the coupling body 5 attached to the sub-speaker 2b is inserted into the first hole 23a, and the first member 51 is further inserted while the locking body 11 is moved backward to the non-locking position. The stopping body 11 engages with the locked portion 51a, and the first member 51 can be fixed to the holding body 23. In other words, the connecting body 5 can be fixed. The connecting body 5 allows the sub speaker 2b to be connected to the main speaker 2a. Removal, rotation, and sliding can be connected to each other.

  Thus, the speaker device 2 in which the main speaker 2a and the sub-speaker 2b are connected can change the dimension H between the longitudinal ends by three dimension changing means.

  One dimension changing means is a first connecting portion having a pivot 53 that connects the first member 51 and the second member 52 so as to be capable of relative rotation, and the sub-speaker 2b is moved around the pivot 53 by the arrow in FIG. By rotating by an appropriate angle in the direction, the linear state is changed to the broken line state, and the dimension H can be changed. Accordingly, as shown in FIG. 5A, when the speaker device 2 formed to have a length corresponding to the height of the display device main body 1 is juxtaposed on both sides on the lower side of the display device main body 1. As shown in FIG. 5B, the dimension H of the speaker device 2 can be changed to a dimension corresponding to the horizontal width of the display device body 1.

  The second dimension changing means is a second connecting portion having the rolling element 12 and the positioning recess 52a. The secondary speaker 2b is slid in the direction of contacting and separating from the main speaker 2a, and the rolling element 12 is moved to the positioning recess 52a. By engaging with any one of them, the dimension H can be changed in a linear state. Therefore, as shown in FIG. 6A, when the speaker device 2 formed to have a length corresponding to the horizontal width of the display device body 1 is attached to both lateral sides of the display device body 1, FIG. As shown in (b), the dimension H of the speaker device 2 can be changed to a dimension corresponding to the height of the display device body 1. In FIG. 6 (b), the space between the main speaker 2a and the sub speaker 2b can be blinded by a blinding member.

  The third dimension changing means is a third connecting portion having the locked portion 51a and the locking body 11, and moves the locking body 11 to the non-locking position, and the locked portion 51a of the locking body 11 and The first member 51 can be pulled out from the first hole 23a and the secondary speaker 2b can be removed, the dimension H can be shortened, and the connector 5 can be used to remove the secondary speaker 2b. By connecting, the dimension H can be lengthened.

  Since the dimension H can be changed as described above, even when the two speaker devices 2 and 2 are juxtaposed on the lower side of the display device main body 1, both sides of the display device main body 1 can be used. The speaker device 2 can be changed to a length corresponding to the horizontal width of the display device body 1 or a length corresponding to the height even when the speaker devices 2 and 2 are attached to the display device. The design can be improved. Moreover, since it can respond with one kind of speaker apparatus 2, the speaker apparatus 2 can be shared by several types of display apparatuses, and the versatility of the speaker apparatus 2 can be improved.
