FIG. 3 is a view showing a state in which the vibration generator is attached to a lamp housing in a lamp for a vehicle according to a first embodiment of the present disclosure, and FIG. 4 is an enlarged view of the vibration generator in FIG. 3, FIG. 5 is an enlarged view showing a state in which the second module of the vibration generator in FIG. 3 is removed, and FIG. 6 is an enlarged view of the second module in FIG. 3, FIG. 7 is a view showing a state in which the vibration generator is attached to an outer lens in the lamp for a vehicle according to the first embodiment of the present disclosure, and FIG. 8 is an enlarged view showing a state, in which the second module of the vibration generator in FIG. 7 is removed.Referring to FIGS. 1 to 8, a lamp 10 for a vehicle (hereinafter referred to as a "lamp") according to the present disclosure may include a lamp housing 100 having an interior configured to receive a light source and an outer lens 200 coupled to a side of the lamp housing 100 and configured to cover the interior. More specifically, the outer lens 200 may be fixedly coupled to the lamp housing 100. The light emitted from the light source may spread to the outside through the outer lens 200, so that predetermined light distribution patterns and illumination images may be formed.Here, the lamp 10 according to the present disclosure may generate not only predetermined light distribution patterns and illumination images, like the lamp in the related art, but also sound. More specifically, the lamp 10 according to the present disclosure may output sound by vibrating the lamp housing 100 or the outer lens 200.In order to achieve the above object, the lamp 10 according to the present disclosure may include a vibration generator 400 fixed to the lamp housing 100 or the outer lens 200. The vibration generator 400 may be configured to output sound by vibrating the lamp housing 100 or the outer lens 200. FIGS. 3 to 6 show states in which the vibration generator 400 is fixed to the lamp housing 100, and FIGS. 7 and 8 show states in which the vibration generator 400 is fixed to the outer lens 200. The vibration generator 400 may be accommodated in the internal space formed in the lamp housing 100.Here, referring to FIGS. 1 and 2, the vibration generator 400 may have a structure in which a plurality of modules are coupled to each other. More specifically, the vibration generator 400 may include a first module 410 and a second module 420 arranged to face the first module 410. Referring to FIGS. 3 to 8, the first module 410 may be fixed to one side of the lamp housing 100 or the outer lens 200, and the second module 420 may be fixed to the other side of the lamp housing 100 or the outer lens 200. More specifically, as illustrated in FIGS. 3 to 6, when the first module 410 is fixed to the lamp housing 100, the second module 420 may also be fixed to the lamp housing 100. As shown in FIGS. 7 and 8, when the first module 410 is attached to the outer lens 200, the second module 420 may also be attached to the outer lens 200. However, the configuration in which the first module 410 and the second module 420 are fixed to the lamp housing 100 need not be interpreted as a configuration in which a portion of the lamp housing 100 to which the first module 410 is fixed and a portion of the lamp housing 100 to which the second module 420 is fixed are identical. Rather, according to the present disclosure, the region of the lamp housing 100 to which the first module 410 is attached and the region of the lamp housing 100 to which the second module 420 is attached may be different from each other, and as described below, the first module 410 and the second module 420 are spaced apart from each other while facing each other.Referring to FIGS. 1 and 2, the first module 410 may include a first magnet 412. The first magnet 412 may be a permanent magnet. Moreover, the second module 420 may include a second magnet 422 provided to face the first magnet 412. The second magnet 422 may be a permanent magnet. More specifically, the first magnet 412 and the second magnet 422 may be disposed to exert a repulsive force therebetween. Here, the second module 420 may further include a second magnet mounting portion 424 configured to receive the second magnet 422 and a coil member 426 provided on one side of the second magnet 422 and received in the second magnet mounting portion 424. For example, as illustrated in FIGS. 1 and 2, the coil member 426 may be provided so as to surround an outer periphery of the second magnet 422. According to the present disclosure, a constant distance between the first module 410 and the second module 420 is maintained by the repulsive force between the first magnet 412 and the second magnet 422 at normal times. In the case where an electric current is supplied to the coil member 426, a force applied between the first module 410 and the second module 420 is changed with an electromagnetic force over time, so that the first module 410 vibrates. Thus, when the lamp housing 100 or the outer lens 200 to which the first module 410 is mounted vibrates, sound can be output from the lamp 10.Here, as illustrated in FIGS. 3 to 8, the first module 410 may further include a first magnet mounting portion 414 to which the first magnet 412 is mounted. For example, the first magnet fixing portion 414 may have an approximately circular plate shape. In this case, the first magnet fixing portion 414 according to the present disclosure may be bonded to the lamp housing 100 or the outer lens 200. For example, the first magnet fixing portion 414 may be fixedly coupled to the lamp housing 100 or the outer lens 200 by an adhesive or an adhesive tape. A structure in which the second module 420 of the vibration generator 400 is fixed to the lamp housing 100 or the outer lens 200 will be described in detail below.FIG. 8 is an enlarged view showing a state in which the second module of the vibration generator in FIG. 7 is removed, and FIG. 9 is a view showing a state in which the vibration generator is attached to a lamp housing of a lamp for a vehicle according to a second embodiment of the present disclosure.

The frame body 424 amay have the shape of a plate, for example. FIGS. 4, 6, 7, and 8 show states in which the two frame extensions 424 bextend from an outer circumferential surface of the frame body 424 ain a direction perpendicular to a direction in which the frame body 424 aextends after bending. FIGS. 9 to 14 show states in which the two frame extensions 424 bextend in a direction parallel to the direction in which the frame body 424 aextends. However, FIGS. 9 to 11 show states in which the frame extensions 424b extend while forming a stepped portion together with the frame body 424a. FIGS. 12 to 14 show states in which the frame extensions 424b extend on the same plane as the frame extension 424b.In this case, according to the first embodiment of the present disclosure, the two frame extensions 424 bmay be inserted between the two first protrusions 310. A shortest distance between the two first protrusions 310 may be shorter than a shortest distance between the two frame extensions 424 b.More specifically, as illustrated in FIGS. 3 to 8, according to an aspect of the first embodiment of the present disclosure, the two frame extensions 424 bmay extend parallel to the direction in which the first protrusion 310 protrudes from the inner surface of the lamp housing 100 or the outer lens 200. FIGS. 3 to 6 show states in which the first protrusions 310 protrude from the inner surface of the lamp housing 100, and the two frame extensions 424 bare parallel to the direction in which the first protrusions 310 protrude. FIGS. 7 and 8 show states in which the first protrusions 310 protrude from the inner surface of the outer lens 200, and the two frame extensions 424 bare parallel to the direction in which the first protrusions 310 protrude.Here, as shown in FIGS. 3 to 8, according to an aspect of the first embodiment of the present disclosure, the first protrusions 310 may include a first first protrusion 310 athat protrudes from the inner surface of the lamp housing 100 or the outer lens 200, and first second protrusions 310 bthat extend from two opposite sides of the first first protrusion 310 ain a direction in which the first second protrusions 310 bsurround the frame extension 424 b. In this case, the first protrusion 310 including the first first protrusion 310 aand the first second protrusions 310 bmay have an approximately U-shaped cross-sectional structure. The frame extension 424 bmay be surrounded by the first first protrusion 310 aand the first second protrusions 310 b. FIGS. 3 to 6 show the first protrusion 310 including the first first protrusion 310 aand the first second protrusions 310 bin the case that the first protrusion 310 protrudes from the lamp housing 100. FIGS. 7 and 8 show the first protrusion 310 including the first first protrusion 310 aand the first second protrusions 310 bin the case that the first protrusion 310 protrudes from the outer lens 200.With continuing reference to FIGS. 3 to 8, according to an aspect of the first embodiment of the present disclosure, the frame extension 424 band the first protrusion 310 may be provided so as to be in contact with each other. In this case, the frame extension 424 band the first protrusion 310 may be configured to engage with each other. Therefore, the second magnet fixing portion 424 and the first protrusion 310 can be prevented from being decoupled.More specifically, a first concave-convex portion 424 b- 1 having a concave-convex shape may be formed in a region of the frame extension 424 bfacing the first protrusion 310, and a second concave-convex portion 310- 1 engaged with the first concave-convex portion 424 b- 1 may be formed in a region of the first protrusion 310 corresponding to the first concave-convex portion 424 b- 1. That is, the first concave-convex portion 424 b- 1 and the second concave-convex portion 310- 1 may be provided to be interlocked. For example, as shown in FIGS. 3 to 8, the first concave-convex portion 424 b- 1 may have a shape protruding outward from the frame extension 424 b, and the second concave-convex portion 310- 1 may have a hole shape formed by the first protrusion 310. However, instead of the hole shape, the second concave-convex portion 310- 1 may have a shape recessed from an outer surface of the first protrusion 310. FIGS. 3 to 6 show states in which the second concave-convex portion 310- 1 is formed in the first protrusion 310 protruding from the lamp housing 100. FIGS. 7 and 8 show states in which the second concave-convex portion 310- 1 is formed in the first protrusion 310 protruding from the outer lens 200.Referring to the above description, according to an aspect of the first embodiment of the present disclosure, the second module 420 may be fixedly coupled to the lamp housing 100 or the outer lens 200 by moving toward the first module 410. In particular, according to an aspect of the first embodiment of the present disclosure, the first concave-convex portion 424 b- 1 and the second concave-convex portion 310- 1 may be engaged with each other as the second module 420 moves toward the first module 410 such that the second module 420 may be fixedly coupled to the lamp housing 100 or the outer lens 200.In contrast, as shown in FIGS. 9 to 14, the lamp housing 100 or the outer lens 200 according to another aspect of the first embodiment of the present disclosure may include second protrusions in addition to the first protrusions 310.

More specifically, the second protrusion 320 may be bent from an end of the first protrusion 310 in a direction away from the lamp housing 100 or the outer lens 200. FIGS. 9 to 11 show states in which the first protrusion 310 and the second protrusion 320 protrude from the lamp housing 100. FIGS. 12 to 14 show states in which the first protrusion 310 and the second protrusion 320 protrude from the outer lens 200.In this case, according to another aspect of the first embodiment of the present disclosure, the two frame extensions 424 bmay extend in a direction away from the two opposite sides of the frame body 424 aand extend in a direction parallel to a direction in which the second protrusions 320 extend. Moreover, the two frame extensions 424 band the frame body 424 amay be accommodated in a space defined by the first protrusions 310 and the second protrusions 320.As illustrated in FIGS. 9 to 11, according to another aspect of the first embodiment of the present disclosure, in the case that the first protrusions 310 and the second protrusions 320 are provided on the lamp housing 100, the two first protrusions 310 may protrude from a lower portion of the inner surface of the lamp housing 100 that extends in a direction (e.g., a horizontal direction) intersecting an up / down direction, and the second protrusions 320 may be provided as two second protrusions 320 that are respectively bent from the two first protrusions 310 and spaced apart from each other.With continuing reference to FIGS. 9 to 11, in the case that the first protrusions 310 and the second protrusions 320 are provided on the lamp housing 100, the two second protrusions 320 may each include a second first protrusion 321 having a first length, which is a length by which the second first protrusion 321 is bent and extends from the first protrusion 310, and a second second protrusion 322 connected to the second first protrusion and having a second length, which is a length by which the second second protrusion 322 is bent and extends from the first protrusion 310, wherein the second length may be shorter than the first length. In this case, a stepped portion may be formed in a region of the second protrusion 320 where the second first protrusion 321 and the second second protrusion 322 meet. In this case, the frame body 424 amay be provided in a space between the two second protrusions 322. More specifically, the frame body 424 amay be provided to face the stepped portion connecting the second first protrusion 321 and the second second protrusion 322 while being in contact with the stepped portion.
