Alternatively, the case (20C''') may have an angular open ring shape in which a portion of the ring is cut off.

[0134]

[0135] Referring to FIGS. 21 and 22, the speaker assembly (20B) can be inserted into the holes (24H, 25H) of the case (20C) of the base (20). The shape of the speaker assembly (20B) can correspond to the shape of the holes (24H, 25H). For example, the holes (24H, 25H, see FIG. 6; 24H'', 25H'', see FIG. 19) can be round (i.e., circular or oval) holes, and the speaker assembly (20B) can have a flat cylindrical shape. For another example, the holes (24H', 25H', see FIG. 18; 24H''', 25H''', see FIG. 20) can be angular holes, and the speaker assembly (20B) can have a flat prism shape. The speaker assembly (20B) may be referred to as an external speaker (20B). The speaker assembly (20B) may include a speaker (20Ba) and a battery (20Bb). The speaker (20Ba) and the battery (20Bb) may be mounted inside the housing (20Bc) of the speaker assembly (20B).

[0136] The speaker (20Ba) can convert an electroacoustic signal into sound waves and output them. The speaker (20Ba) may include a diaphragm that vibrates to generate sound waves. The speaker (20Ba) can wirelessly communicate with a user's terminal or system via Bluetooth or Wi-Fi. For example, the speaker (20Ba) may be located at the front of the speaker assembly (20B).

[0137] The battery (20Bb) can be electrically connected to the speaker (20Ba) and can provide power to the speaker (20Ba). The battery (20Bb) may be a rechargeable secondary battery. For example, the battery (20Bb) may be located at the rear of the speaker assembly (20B).

[0138] The housing (20Bc) can be inserted into the holes (24H, 25H). The height of the housing (20Bc) can correspond to the height of the holes (24H, 25H). The bottom of the housing (20Bc) inserted and coupled to the holes (24H, 25H) can be positioned parallel to the bottom of the bottom case (24).

[0139] For example, the width (diameter) of the housing (20Bc) may be larger than the width (diameter) of the hole (24H, 25H), and the housing (20Bc) may be press-fitted into the hole (24H, 25H) and joined.

[0140] For another example, the supporter (29) may protrude from the bottom case (24) into the hole (24H, 25H) and support the housing (20Bc). The supporter (29) may cover at least a portion of the hole (24H, 25H) from below the hole (24H, 25H). The supporter (29) may be formed as one body with the bottom case (24), or may be detachably connected to the bottom case (24) through a fastening member such as a screw.

[0141] Accordingly, the speaker assembly (20B) can be detachably coupled to the base (20). The speaker hole of the speaker assembly (20B) can be formed on the upper surface of the housing (20Bc) and can face the speaker (20Ba). The speaker (20Ba) of the speaker assembly (20B) coupled to the base (20) can output sound upward. In this case, since the sound of the display device (1) spreads upward from the base (20), the sound quality can be improved.
