[0119] The yoke 102a can form one side of the speaker unit 102. The yoke 102a can be located at the hole 1011H of the first case 1011. The yoke 102a can have a cup shape that is open in a forward direction.

[0120] The magnet 102b can be disposed inside the yoke 102a. The magnet 102b can have a coin shape. The plate member 102c can be coupled to the magnet 102b and can have a shape corresponding to the magnet 102b.

[0121] The bobbin 102d can be located at an air gap between the plate member 102c and the yoke 102a and can have a hollow cylindrical shape. The coil 102e can be formed or wound around an outer circumferential surface of the bobbin 102d and can be referred to as a voice coil 102e.

[0122] The diaphragm 102g can be coupled in front of the bobbin 102d. The diaphragm 102g can have a flat disc shape. Alternatively, the diaphragm 102g can have a dome or a cone shape. The diaphragm 102g having a cone shape can be referred to as a cone paper 102g. The damper 102h having elasticity can be coupled to the speaker frame 102F and can be coupled to the diaphragm 102g or the bobbin 102d to support the diaphragm 102g.

[0123] The edge 102i can be located between the diaphragm 102g and the speaker frame 102F. The edge 102i can be coupled to an outer side surface of the diaphragm 102g and an inner side surface of the speaker frame 102F. The edge 102i can have elasticity and can support movement of the diaphragm 102g. The edge 102i can be referred to as a speaker edge 102i or a peripheral edge 102i.

[0124] If a magnetic line of force is formed in an air gap between the magnet 102b and the yoke 102a and an electric current flows in the coil 102e, a Lorentz force can be generated. The magnitude of the Lorentz force can be proportional to the magnitude of the magnetic line of force (magnetic flux density), the magnitude of the electric current, and the length of the coil wound, and the direction of the force can be perpendicular to a plane formed by the magnetic flux density and the electric current.

[0125] Thus, the diaphragm 102g can vibrate back and forth. In correspondence with the vibration of the diaphragm 102g, the internal air of the speaker box 101 can resonate to change the internal pressure.

[0126] The speaker frame 102F can include a support portion 102Fa and a recessed portion 102Fb. The support portion 102Fa can be located at the support portion 1012S.

The front surface of the first portion 102ia can be aligned with the front surface of the support portion 102Fa.

[0127] The plate body 104 can be located at the combined portion 1012Ea (refer to Figure 12 ) of the first pressing portion 1012E1, and can cover the front of the speaker unit 102. The plate body 104 can be spaced apart from the recessed portion 1012Eb (refer to Figure 12 ) of the first pressing portion 1012E1. The plate body 104 can include a metal material such as iron (Fe).

The plate body 104 can be attached or bonded to the combined portion 1012Ea. Thus, the plate body 104 can be combined with the box 101.

[0128] The fixing portion 1012D (refer to Figure 13 ) can be located inside the bezel of the plate body 104. The fixing portion 1012D can be formed at the pressing portion 1012E. The front end of the fixing portion 1012D can be coplanar with the front surface of the combined portion 1012Ea. That is, the depth of the front end of the fixing portion 1012D can be the same as the depth of the front surface of the combined portion 1012Ea, or the depth of the front end of the fixing portion 1012D can be smaller than the depth of the front surface of the recessed portion 1012Eb, with respect to the front surface of the second box 1012. Thus, the plate body 104 can be located on the combined portion 1012Ea and the fixing portion 1012D.

[0129] The first fixing portion 1012Da (refer to Figure 13 ) can protrude forward from the recessed portion 1012Eb, and can have a fastening hole for a screw. The second fixing portion 1012Db (refer to Figure 13 ) can protrude forward from the second pressing portion 1012E2, and can have a fastening hole for a screw. The third fixing portion 1012Dc (refer to Figure 13) can protrude forward from the second pressing portion 1012E2, and can have a fastening hole for a screw. The first to third fixing portions 1012Da, 1012Db, 1012Dc can be located at the vertices of a triangle (refer to the dotted line). A plurality of fastening members F1, F2, F3 such as screws can be fastened to the first to third fixing portions 1012Da, 1012Db, 1012Dc by being inserted through the plate body 104. Alternatively, the plate body 104 can be attached to or joined to the first to third fixing portions 1012Da, 1012Db, 1012Dc. Figure 15

[0130] Thus, the plate body 104 can be firmly combined with the case 101, and as a result, the shaking of the plate body 104 can be minimized, thereby improving stability. In addition, the contact between the plate body 104 and the recessed portion 1012Eb can be minimized or prevented.

[0131] The diaphragm 102g of the speaker unit 102 can vibrate back and forth, and output sound toward the plate body 104 side. The plate body 104 can direct the sound of the speaker unit 102 toward the opening 101H side. The opening 101H can be an outlet of a chamber 101P between the speaker unit 102 and the plate body 104, and can be formed between the plate body 104 and the third pressing portion 1012E3. The chamber 101P can be referred to as a space 101P.

[0132] The cushion pad 103 can be located between the speaker frame 102F of the speaker unit 102 and the plate body 104. The cushion pad 103 can be opposite the opening 101H. The cushion pad 103 can extend along the first portion 1012Eba of the recessed portion 1012Eb, and can have an arc shape. The cushion pad 103 can be curved. The cushion pad 103 can have a curvature. The back of the cushion pad 103 can be in contact with the speaker frame 102F. The back of the cushion pad 103 can be adhered to the speaker frame 102F. The back of the cushion pad 103 can be adhered to the support portion 102Fa of the speaker frame 102F and the first portion 102ia of the edge 102i. The front of the cushion pad 103 can be in contact with the plate body 104. The front of the cushion pad 103 can be adhered to the plate body 104. If an external force is applied in the thickness direction of the cushion pad 103, the cushion pad 103 can be compressed in the thickness direction. If the external force is removed, the cushion pad 103 can return to its original state. The original thickness of the cushion pad 103 can be greater than the interval between the speaker frame 102F and the plate body 104. The cushion pad 103 can be pressed by the plate body 104. For example, the cushion pad 103 can include an ethylene-vinyl acetate (EVA) material.

[0133] ​Thus, the cushion 103 can occupy a portion of the cavity 101P between the speaker unit 102 and the board body 104. The cushion 103 can reduce vibration of the board body 104.

[0134] With reference to Figure 16 and Figure 17 , the center line CL can extend along a radial direction of the diaphragm 102g via a center of the diaphragm 102g of the speaker unit 102. The center line CL can intersect with a sound output direction SD of the speaker 100.
