The substrate 32 can be coupled to the front surface of the frame 60. The substrate 32 can have a plate shape, or can include a plurality of straps spaced apart from each other in the vertical direction. The substrate 32 can be formed of at least one of polyethylene terephthalate (PET), glass, polycarbonate (PC), or silicon. The substrate 32 can be a printed circuit board (PCB).

Accordingly, the timing controller board P2 can provide digital video data and a timing control signal to the display panel 10 through the source PCB 12.

Speakers 100 can be coupled to the frame 60. The speakers 100 can be located between the frame 60 and the back cover 70, and can be coupled to the rear surface of the frame 60. The speakers 100 can be adjacent to one side of the frame 60. The speakers 100 can be adjacent to the lower side of the frame 60, and can provide sound to the front lower part of the display device 1. For example, a plurality of speakers 100A and 100B can be coupled to the frame 60.

A sound device can include the speakers 100, a frame 60, components (holders described later) which couple the speakers 100 to the frame 60. The frame 60 can be the frame 60 of the above-described display device. Alternatively, the frame 60 can be a frame of an audio device.

Referring to FIG. 6, a speaker frame 101 can support components of a speaker unit 100U of the speaker 100. The speaker frame 101 can be installed in a speaker box 101H of the speaker 100, which will be described later. The speaker 100 can be referred to as a speaker assembly 100 or a speaker module 100.

A first plate 102 can form one side of the speaker unit 100U. A pole piece 102a can protrude from the central portion of the first plate 102, and can have the shape of a hollow cylinder or a solid cylinder. A second plate 103 can be spaced apart from the first plate 102, and can have a ring shape. A portion of the pole piece 102a can penetrate the second plate 103, and an air gap can be formed between the second plate 103 and the pole piece 102a.

A magnet 104 can be disposed between the first plate 102 and the second plate 103, and can have a ring shape. A portion of the pole piece 102a can pass through the magnet 104. A bobbin 105 can be located in the air gap between the pole piece 102a and the second plate 103 and an air gap between the pole piece 102a and the magnet 104, and can have the shape of a hollow cylinder extending in the length direction of the pole piece 102a. A coil 106 can be formed or wound on the outer circumferential surface of the bobbin 105, and can be referred to as a voice coil. A terminal 107c and a tinsel wire 107d can transmit electrical energy output from an amplifier to the coil 106.

A spider 108 can have elasticity. The spider 108 can be located between the bobbin 105 and the speaker frame 101, and can be coupled to the bobbin 105 and the speaker frame 101. The spider 108 can support the bobbin 105, and can be referred to as a damper 108.

One side of a diaphragm 107 can be coupled or attached to the bobbin 105, and the other side of the diaphragm 107 can be supported by an edge 107a having elasticity. For example, the diaphragm 107 can have a cone or dome shape. A gasket 107b can be provided on the side surface of the edge 107a, and can prevent interference of the vibrating diaphragm 107 with surrounding devices. For example, a dust cap 109 can cover the central portion of the diaphragm 107, and can prevent dust or the like from flowing into a magnetic circuit.

When lines of magnetic force are generated in the air gap by the magnet 104 and current flows along the coil 106, Lorentz force can be generated. The magnitude of the Lorentz force can be proportional to the size of the lines of magnetic force (a magnetic flux density), the amount of current, and the length of the wound coil 106, and the direction of the Lorentz force can be at a right angle to a plane formed by the magnetic flux density and current.

Accordingly, the diaphragm 107 can vibrate in the length direction of the pole piece 102a. Based on FIG. 6, when the diaphragm 107 moves upward, positive (+) sound pressure can be generated, when the diaphragm 107 moves downward, negative (−) sound pressure can be generated, and the speaker unit 100U can provide sound upward. Depending on such vibration of the diaphragm 107, air in the speaker box 101H can also resonate, and the pressure in the speaker box 101H can be changed.

Referring to FIG. 7, a hole 13H can be formed in the side frame 13 adjacent to the speakers 100 (see FIG. 5). For example, the speakers 100 can be adjacent to the second long side LS2, i.e., the lower side of the display device 1, and the hole 13H can be formed in a portion of the side frame 13 which defines the second long side LS2. Sound output from the speakers 100 can be provided to the outside through the hole 13H. The hole 13H can be formed as holes spaced apart from each other. A plurality of holes 13H can face a plurality of speakers 100.

Referring to FIG. 8, fixing parts 61 can be formed, for example, by pressing the frame 60 from the front to the rear. The fixing parts 61 can be referred to as forming parts 61. A fixing hole 61b can be formed to penetrate the fixing part 61. For example, a plurality of fixing parts 611 and 612 can be spaced apart from each other.

Referring to FIGS. 9 and 10, the components of the speaker unit 100U descried above with reference to FIG. 6 can be mounted in and on the speaker box 101H of the speaker 100.

Accordingly, the speakers 100 can be mounted on the rear part of the frame 60.

Hooks 101K can protrude from one side of the speaker box 101H. A first hook 101Ka and a second hook 101Kb can protrude from the upper side of the speaker box 101H, and can be spaced apart from each other in the thickness direction of the speaker box 101H. As an example, the first hook 101Ka and the second hook 101Kb can face each other, and can be spaced apart from a vertical line L passing through the center of the speaker box 101H by a designated distance. As another example, the first hook 101Ka and the second hook 101Kb can be disposed alternately.

A first insertion hole 61Ha can be formed in the frame 60 adjacent to the left side 60L of the frame 60, and the first hook 101Ka can be hooked to the first insertion hole 61Ha. A second insertion hole can be formed in the frame 60 adjacent to the right side 60R of the frame 60, and the second hook 101Kb can be hooked to the second insertion hole.

Here, as the first and second hooks 101Ka and 101Kb are arranged eccentrically from the vertical line passing through the center of the speaker box 101H or alternately, incorrect insertion of the first and second hooks 101Ka and 101Kb into the first and second insertion holes 60Ha can be prevented. Meanwhile, the hooks 101K can be omitted, and in this instance, the speakers 100 can be mounted on the frame 60 only through the holders 120.

Accordingly, transmission of vibration of the speaker 100, coupled to the frame 60, to the frame 60 can be suppressed by the holder 120.

The body 120c can have a ring shape. The diameter of the body 120c can be smaller than the diameter of the base 110a. A plurality of legs 120c1 and 120c2 can protrude from one surface of the body 120c facing the base 110a toward the plurality of holes 110b1 and 110b2.

The head 120b can be opposite the body 120c with respect to the neck 120a. The head 120b can protrude from one end of the neck 120a in the radial direction of the neck 120a, and can extend in the circumferential direction of the neck 120a. The diameter of the head 120b can be greater than the diameter of the neck 120a. That is, a step can be formed between the head 120b and the neck 120a.

A first holder 121 can be aligned with the first protrusion 110c1, and can be seated on the base 110a.

First and second projections 120b1 and 120b2 can protrude from the inner circumferential surface of the head 120b toward the first protrusion 110c1, and can be adjacent to the outer circumferential surface of the first protrusion 110c1. The first and second projections 120b1 and 120b2 can be disposed alternately with the first and second stoppers 110d1 and 110d2.

Accordingly, the first holder 121 can be detachably coupled to the first protrusion 110c1. The first holder 121 can be caught by the bridge 110b and the stoppers 110d1 and 110d2 to be fixed to the coupling part 110.

Referring to FIG. 13 together with FIGS. 9 and 10, the plurality of holders 121, 122, 123, and 124 can have the same shape. The coupling structure between the first holder 121 and the first protrusion 110c1 described above with reference to FIGS. 11 and 12 can be identically applied as coupling structures between the remaining holders 122, 123, and 124 and the remaining protrusions 110c2, 110c3, and 110c4.

The coupling parts 110 can include a plurality of coupling parts 111 and 112. Each of the plurality of coupling parts 111 and 112 can include the above-described base 110a, bridge 110b, protrusions 110c, and stoppers 110d.

The first coupling part 111 can be formed on one side of the speaker box 101H. The first coupling part 111 can be located on or adjacent to one side 101HR of the speaker box 101H. The first holder 121 can be detachably coupled to the first protrusion 110c1 of the first coupling part 111. The second holder 122 can be detachably coupled to the second protrusion 110c2 of the first coupling part 111. The first and second holders 121 and 122 can be symmetrical to each other with respect to the base 110a of the first coupling part 111. The first and second holders 121 and 122 can be disposed before and after the base 110a.

A second coupling part 112 can be formed on the other side of the speaker box 101H. The second coupling part 112 can be located on or adjacent to another side 101HL of the speaker box 101H. A third holder 123 can be detachably coupled to the first protrusion 110c1 of the second coupling part 112. A fourth holder 124 can be detachably coupled to the second protrusion 110c2 of the second coupling part 112. The third and fourth holders 123 and 124 can be symmetrical to each other with respect to the base 110a of the second coupling part 112. The third and fourth holders 123 and 124 can be disposed before and after the base 110a.

The first and third holders 121 and 123 can be located on a first surface 1011 of the speaker box 101H. The first surface 1011 can be the front surface of the speaker box 101H. A first groove 101H1 can be formed by depressing the first surface 1011 toward the base 110a of the first coupling part 111. The first holder 121 can be located in the first groove 101H1, and the first groove 101H1 can be formed along the side surface of the first holder 121. A third groove 101H3 can be formed by depressing the first surface 1011 toward the base 110a of the second coupling part 112. The third holder 123 can be located in the third groove 101H3, and the third groove 101H3 can be formed along the side surface of the third holder 123.

The second and fourth holders 122 and 124 can be located on a second surface 1012 of the speaker box 101H. The second surface 1012 can be the rear surface of the speaker box 101H. A second groove 101H2 can be formed by depressing the second surface 1012 toward the base 110a of the first coupling part 111. The second holder 122 can be located in the second groove 101H2, and the second groove 101H2 can be formed along the side surface of the second holder 122. A fourth groove 101H4 can be formed by depressing the second surface 1012 toward the base 110a of the second coupling part 112. The fourth holder 124 can be located in the fourth groove 101H4, and the fourth groove 101H4 can be formed along the side surface of the fourth holder 124.

Accordingly, the holders 121, 122, 123, and 124 can be mounted on the front and rear surfaces of the speaker box 101H. The holders 120 can be coupled to the fixing parts 61 of the frame 60. A distance between these holders 121, 122, 123, and 124 can be constant regardless of the size of the speaker box 101H. That is, the holders 121, 122, 123, ad 124 can be fixed to specific positions of speaker boxes 101H of various sizes, and correspondingly, the fixing parts 61 of the frame 60 can be constant. That is to say, speaker boxes 101H of various sizes can be mounted on the fixing parts 61 formed at specific positions of the frame 60, and thereby, the fixing parts 61 can be applied in common to the speaker boxes 101H of various sizes.

The fixing part 61 can include a fixing body 61a and the fixing hole 61b. the fixing part 61 can have an overall truncated conical shape. The fixing body 61a can include an inclined portion 61aa, a horizontal portion 61ab, and a vertical portion 61ac. The inclined portion 61aa can protrude rearward from the rear surface of the frame 60, and the diameter of the inclined portion 61aa can become smaller as the inclined portion 61aa is away from the rear surface. The horizontal portion 61ab can be bent from the end of the inclined portion 61aa to the inside of the inclined portion 61aa, and can have a ring shape parallel to the rear surface of the frame 60. The vertical portion 61ac can be bent from the end of the horizontal portion 61ab to the rear surface of the frame 60. The horizontal portion 61ab and the vertical portion 61ac can define the boundary of the fixing hole 61b.

A diameter Da of the neck 120a of the holder 120 can be equal to or smaller than a diameter Dh of the fixing hole 61b. A diameter Db of the head 120b of the holder can be greater than the diameter Dh of the fixing hole 61b. A diameter Dc of the body 120c of the holder 120 can be greater than the diameter Dh of the fixing hole 61b. A distance D20 between the body 120c and the head 120b as the length of the neck 120a can be equal to or greater than a length Lac of the vertical portion 61ac. When the neck 120a and the head 120b are inserted into the fixing part 61 through the fixing hole 61b, the neck 120a can be located in the fixing hole 61b, the body 120c can be caught by the horizontal portion 61ab, and the head 120b can be caught by the vertical portion 61ac. That is, the holder 120 can be detachably coupled to the fixing part 61.

As an example, the first surface 1011 of the speaker box 101H can face the rear surface of the frame 60 (see FIG. 8). In this case, the first holder 121 can be coupled to a first fixing part 611, and the third holder 123 can be coupled to a second fixing part 612. Thereby, the speaker 100 can be mounted on the frame.

As another example, the second surface 1012 of the speaker box 101H can face the rear surface of the frame 60 (see FIG. 8). In this case, the second holder 122 can be coupled to the second fixing part 612, and the fourth holder 124 can be coupled to the first fixing part 611. Thereby, the speaker 100 can be mounted on the frame.

Referring to FIG. 14, unlike the above-described holder 120, first and second projections 120b1′ and 120b2′ of a holder 120′ can be formed in an arc shape along the outer circumferential surface of the protrusion 110c, and can be adjacent to the outer circumferential surface of the protrusion 110c. In addition, serration-shaped projections 120P can be formed on the side surface of the neck 120a, and thereby, the neck 120a of the holder 120′ can be in close contact with the vertical portion 61ac (see FIG. 13). Further, serration-shaped projections 120Q can be formed on the side surface of the head 120b, and thereby, the head 120b of the holder 120′ can smoothly pass through the fixing hole 61b (see FIG. 13).

Referring to FIGS. 15 and 16, the speakers 100 can be located behind the frame 60. The first speaker 100A can be adjacent to the lower side 60D and the left side 60L of the frame 60. The first surface 1011 of the first speaker 100A can face the rear surface of the frame 60, and the second surface 1012 of the first speaker 100A can form the rear surface of the first speaker 100A.

The second speaker 100B can be adjacent to the lower side 60D and the right side 60R of the frame 60. The second surface 1012 of the second speaker 100B can face the rear surface of the frame 60, and the first surface 1011 of the second speaker 100B can form the rear surface of the second speaker 100B.

The first and second speakers 100A and 100B can be inverted (or rotated or flipped) 180 degrees from each other with respect to a straight line V-V′ between the first and second speakers 100A and 100B. For example, the straight line V-V′ can be parallel to a vertical line passing through the center of the frame 60.

The first holder 121 of the first speaker 100A can be coupled to the first fixing part 611 (see FIG. 8), and the third holder 123 of the first speaker 100A can be coupled to the second fixing part 612 (see in FIG. 8). At this time, the second holder 122 and the fourth holder 124 can be coupled to or separated from the first speaker 100A.

The second holder 122 of the second speaker 100B can be coupled to a fourth fixing part 614, and the fourth holder 124 of the second speaker 100B can be coupled to a third fixing part 613. At this time, the first holder 121 and the third holder 123 can be coupled to or separated from the second speaker 100B. Here, the third and fourth fixing parts 613 and 614 can have the same shape as the first and second fixing parts 611 and 612 (see FIG. 8), and can be adjacent to the right side 60R of the frame 60. A distance between the third and fourth fixing parts 613 and 614 can be the same as a distance between the first and second fixing parts 611 and 612.

Accordingly, the first and second speakers 100A and 100B can be mounted on the frame 60, and the first and second speakers 100A and 100B can be the same type of speakers having different arrangement relationships with respect to the frame 60.

A groove 101U can be formed on the upper side of the speaker box 101H. The groove 101U can include a horizontal surface 101Ua and a vertical surface 101Ub. A cable connector 100C can be mounted in the groove 101U. The groove 101U of the first speaker 100A can be formed on the right side of the speaker box 101H. The groove 101U of the second speaker 100B provided in the shape of the first speaker 100A inverted 180 degrees can be formed on the left side of the speaker box 101H.

A first cable connector 100Ca can be mounted on the horizontal surface 101Ua (see FIG. 15) or the vertical surface 101Ub (see FIG. 16) of the groove 101U of the first speaker 100A. One end of a first cable Ca can be coupled to the first cable connector 100Ca on the right (see FIG. 15) or above (see FIG. 16) of the first cable connector 100Ca, and the first cable Ca can be electrically connected to the first speaker 100A through the first cable connector 100Ca. The other end of the first cable Ca can be electrically connected to the amplifier. The amplifier can be provided on the main board P3 (see FIG. 5).

A second cable connector 100Cb can be mounted on the horizontal surface 101Ua (see FIG. 15) or the vertical surface 101Ub (see FIG. 16) of the groove 101U of the second speaker 100B. One end of a second cable Cb can be coupled to the second cable connector 100Cb on the left (see FIG. 15) or above (see FIG. 16) of the second cable connector 100Cb, and the second cable Cb can be electrically connected to the second speaker 100B through the second cable connector 100Cb. The other end of the second cable Cb can be electrically connected to the amplifier. The amplifier can be provided on the main board P3 (see FIG. 5).

That is, the first cable connector 100Ca and the second cable connector 100Cb can be aligned with each other in the leftward and rightward directions, and can face the same or opposite directions. Accordingly, the length of the first and second cables Ca and Cb can be minimized, and the need for cable holders for organizing the first and second cables Ca and Cb can be reduced.

Referring to FIG. 15, for example, the speaker unit 100U can be mounted on the lower side of the speaker box 101H, and the diaphragm 107 of the speaker unit 100U can output sound downward. For example, the speaker unit 100U can be a full range speaker unit. Air within the speaker unit 101H can vibrate in response to operation of the speaker unit 100U. A duct 100D can be installed in the speaker box 101H, and can provide a flow path through the air within the speaker box 101H passes. An outlet 100De of the duct 100D can be formed at the lower side of the speaker box 101H, and can be spaced apart from the speaker unit 100U. The duct 100D can provide a low-frequency sound downward. That is, the sound from the duct 100D, which has weak sound directivity, can be less influenced by arrangement of the duct 100D. The speaker unit 100U, which outputs a relatively high-frequency sound, can be located relatively outside compared to the duct 100D.

A distance D1a between the speaker unit 100U of the first speaker 100A and the straight line V-V′ can be greater than a distance D1b between the outlet 100De of the duct 100D of the first speaker 100A and the straight line V-V′. A distance D2a between the speaker unit 100U of the second speaker 100B and the straight line V-V′ can be greater than a distance D2b between the outlet 100De of the duct 100D of the second speaker 100B and the straight line V-V′. For example, the distances D1a and D2a can be equal to each other and the distances D1b and D2b can also be equal to each other, and in this case, sounds provided by the first and second speakers 100A and 100B can be symmetrical. Further, as the speaker units 100U of the first and second speakers 100A and 100B are disposed relatively far apart, the sense of stereo separation of sounds can be improved.

Referring to FIG. 16, for example, a first speaker unit 100Ua can be mounted on the lower side of the speaker box 101H, and the diaphragm 107 of the first speaker unit 100Ua can provide sound downward. For example, the first speaker unit 100Ua can be a full range speaker unit. A second speaker unit 100Ub can be mounted in the speaker box 101H, and can provide sound forward (or rearward). For example, the second speaker unit 100Ub can be a woofer. Air within the speaker unit 101H can vibrate in response to operation of the first speaker unit 100Ua and/or the second speaker unit 100Ub. A duct 100E can be installed in the speaker box 101H, and can provide a flow path through the air within the speaker box 101H passes. An outlet 100Ee of the duct 100E can be formed at the lower side of the speaker box 101H, and can be opposite an outlet 100Ue of the second speaker unit 100Ub with respect to the first speaker unit 100Ua. The duct 100E can provide a low-frequency sound downward. That is, the sounds from the duct 100E, which has weak sound directivity, and the second speaker unit 100Ub can be less influenced by arrangement of the duct 100E and the second speaker unit 100Ub. The first speaker unit 100Ua, which outputs a relatively high-frequency sound, can be located relatively outside compared to the second speaker unit 100Ub.

A distance D3c between the outlet 100Ee of the duct 100E of the first speaker 100A and the straight line V-V′ can be greater than a distance D3a between the first speaker unit 100Ua of the first speaker 100A and the straight line V-V′. The distance D3a can be greater than a distance D3b between the outlet 100Ue of the second speaker unit 100Ub and the straight line V-V′. A distance D4c between the outlet 100Ee of the duct 100E of the second speaker 100B and the straight line V-V′ can be greater than a distance D4a between the first speaker unit 100Ua of the second speaker 100B and the straight line V-V′. The distance D4a can be greater than a distance D4b between the outlet 100Ue of the second speaker unit 100Ub of the second speaker 100B and the straight line V-V′. For example, the distances D3a and D4a can be equal to each other, the distances D3b and D4b can also be equal to each other, and the distances D3c and D4c can also be equal to each other. As the first speaker units 100Ua of the first and second speakers 100A and 100B are disposed relatively far apart, the sense of stereo separation of sounds can be improved.

Referring to FIGS. 16 and 17, the diaphragm 107 of the second speaker unit 100Ub, which vibrates back and forth, can be disposed closer to the first surface 1011 than the second surface 1012 of the speaker box 101H. That is, the second speaker unit 100Ub of the first speaker 100A can be disposed closer to the front surface than the rear surface of the speaker box 101H, and the second speaker unit 100Ub of the second speaker 100B can be disposed closer to the rear surface than the front surface of the speaker box 101H.

A guide plate 101P can cover the diaphragm 107 of the second speaker unit 100Ub while being spaced apart from the diaphragm 107. The guide plate 101P can form a portion of the first surface 1011 of the speaker box 101H. The guide plate 101P can be a plate formed of a metal, such as iron (Fe). A space 101S between the diaphragm 107 and the guide plate 101P can be opened downward. Partition walls 101W can include a mount wall 101Wa equipped with the diaphragm 107 mounted thereon and facing the guide plate 101P, and a side wall 101Wb forming the boundary of the space 101S between the mount wall 101Wa and the guide plate 101P.

The mount wall 101Wa can include a first part 101Waa and a second part 101Wab. The first part 101Waa is a portion of the mount wall 101Wa on which the diaphragm 107 is mounted, and can be disposed parallel to the guide plate 101P. The second part 101Wab can extend from the lower side of the first part 101Waa toward the second surface 1012 of the speaker box 101H to be inclined. A gap Gb between the second part 101Wab and the guide plate 101P can be greater than a gap Ga between the first part 101Waa and the guide plate 101P, and can increase as the second part 101Wab becomes closer to the lower side of the speaker box 101H. An outlet of the space 101S, i.e., the outlet 101Ue of the second speaker unit 100Ub, can be formed between the lower side of the guide plate 101P and the lower side of the second part 101Wab. Accordingly, the guide plate 101P and the partition walls 101W can guide sound from the diaphragm 107 of the second speaker unit 100Ub downward.

Referring to FIGS. 18 and 1, a stand 200 of the display device 1 can be coupled to the lower side of the side frame 13, and can support the remaining components of the display device 1. One stand 200 or two or more stands 200 can be provided. Stands 200A and 200B can be spaced apart from each other along the lower side, i.e., the second long side LS2, of the side frame 13. A first stand 200A can be adjacent to the left side, i.e., the first short side SS1, of the side frame 13, and a second stand 200B can be adjacent to the right side, i.e., the second short side SS2, of the side frame 13.

The stand 200 can include a support 201, a coupling part 202, and legs 203. The support 201 can be located under the lower side of the side frame 13. The coupling part 202 can extend upward from the support 201, and can be coupled to the rear surface of the back cover 70. The legs 203 can extend downward from the support 201 to be inclined, and can be separated from each other by a certain angle. A first leg 203a can extend forward from the support 201 to be inclined, and a second leg 203b can extend rearward from the support 201 to be inclined. Accordingly, the stand 200 coupled to the back cover 70 can be placed on the ground to support the components of the display deice 1 excluding the stand 200.

The lower side of the side frame 13 can be located on or adjacent to the upper surface, i.e., a support surface 201S, of the support 201. The width of the support surface 201S in the forward and rearward directions can be smaller than the width of the lower side of the side frame 130. That is, the support surface 201S can cover a portion of the lower side of the side frame 13.

Sound output from the first speaker 100A (see FIG. 16) can be provided to the outside through a first hole 13Ha (see FIG. 7). The first hole 13Ha can include a first outer hole 13Haa facing the diaphragm 107 of the first speaker unit 100Ua (see FIG. 16), and a first inner hole 13Hab facing the outlet 100Ue of the second speaker unit 100Ub (see FIGS. 16 and 17).

Sound output from the second speaker 100B (see FIG. 16) can be provided to the outside through a second hole 13Hb (see FIG. 7). The second hole 13Hb can include a second outer hole 13Hba facing the diaphragm 107 of the first speaker unit 100Ua (see FIG. 16), and a second inner hole 13Hbb facing the outlet 100Ue of the second speaker unit 100Ub (see FIGS. 16 and 17).

The support surface 201S of the first stand 200A can cover some of the first inner hole 13Hab. The first inner hole 13Hab can include a closed hole 13H1, which are covered by the support surface 201S, and an open hole 13H2, which are not covered by the support surface 201S. A space (with reference to the gap Ga in FIG. 17) between the first part 101Waa of the mount wall 101Wa and the guide plate 101P can face the open hole 13H2. The outlet 200Ue of the second speaker unit 100Ub (in FIGS. 16 and 17) can face not only the open hole 13H2 but also the closed hole 13H1. Accordingly, the second speaker unit 100Ub of the first speaker 100A can provide sound to the outside through the first inner hole 13Hab.

The support surface 201S of the second stand 200B can cover some of the second inner hole 13Hbb. The second inner hole 13Hbb can include a closed hole 13H1, which are covered by the support surface 201S, and an open hole 13H2, which are not covered by the support surface 201S. A space (with reference to the gap Ga in FIG. 17) between the first part 101Waa of the mount wall 101Wa and the guide plate 101P can face the closed hole 13H1 and the support surface 201S. A portion of the outlet 200Ue (in FIGS. 16 and 17) of the second speaker unit 100Ub can face the closed hole 13H1 and the support surface 201S, and the remaining portion can face the open hole 13H2.

Accordingly, the second speaker unit 100Ub of the second speaker 100B provided in the shape of the first speaker 100A inverted 180 degrees with respect to the straight line V-V′, can provide sound to the outside through the second inner hole 13Hbb.

The second speaker units 100Ub can be woofers, and can output sound of a low-frequency range (Hz). In this case, there can be little difference in characteristics between the sound from the second speaker unit 100Ub of the first speaker 100A, which is output through the first inner hole 13Hab, and the sound from the second speaker unit 100Ub of the second speaker 100B, which is output through the second inner hole 13Hbb.

Referring to FIGS. 19 to 21, back cover fixing parts 62 can be formed on the rear surface of the frame 60. First to fourth back cover fixing parts 62a, 62b, 62c, and 62d can be located at the vertices of a square. The back cover 70 (see FIGS. 2 and 3) can be coupled to the back cover fixing parts 62. Video electronics standards association (VESA) holes can be formed in the back cover fixing parts 62.

Referring FIGS. 19 and 20, the frame 60 can have a first diagonal length S1 or a second diagonal length S2. The second diagonal length S2 can be greater than the first diagonal length S1. A first hole 101Ha can be formed in the speaker box 101H of the first speaker 100A, and the first back cover fixing part 62a can be located in the first hole 101Ha. A second hole 101Hb can be formed in the speaker box 101H of the second speaker 100B, and the second back cover fixing part 62b can be located in the second hole 101Hb.

Referring to FIG. 21, the frame 60 can have a third diagonal length S3. The third diagonal length S3 can be greater than the second diagonal length S2. The speaker box 101H of the first speaker 100A can be located on the left of the first back cover fixing part 62a. The speaker box 101H of the second speaker 100B can be located on the right of the second back cover fixing part 62b. Accordingly, the first and second speakers 100A and 100B can be mounted on the rear surface of the frame 60 while avoiding the back cover fixing parts 62.

Referring to FIGS. 1 to 21, a sound device can include a frame, a first speaker adjacent to the frame, a second speaker spaced apart from the first speaker, a first holder located between the frame and the first speaker and coupled to the frame and the first speaker, and a second holder located between the frame and the second speaker and coupled to the frame and the second speaker, and the second speaker can have the same shape as the first speaker inverted 180 degrees.

The first speaker can include a speaker box and a speaker unit coupled to the speaker box, and the speaker box can include a first part which faces the frame and to which the first holder is coupled, and a second part which is opposite to the first part to which the second holder is coupled. The first holder and the second holder can be detachably coupled to the first part and the second part, respectively. The speaker box can further include a base formed at one side of the speaker box, a first protrusion protruding from the base toward the frame, and a second protrusion protruding from the base in an opposite direction to the first protrusion, the first holder can be coupled to the first protrusion, and the second holder can be coupled to the second protrusion.

The first protrusion and the second protrusion can be symmetrical to each other with respect to the base, and the first holder and the second holder can be symmetrical to each other with respect to the base.
