Claim 0:
1. A display apparatus, comprising:
a display module including a display panel configured to display an image at a front surface;
a structure at a rear surface of the display module; and
a vibration generator at the structure,
wherein:
the structure includes a nonlinear portion to cover a periphery of the rear surface of the display module along a first direction and a sound emission port spaced apart from the rear surface of the display module;
the vibration generator has a surface facing toward the front surface;
the rear surface of the display module faces away from the front surface and faces toward the surface of the vibration generator;
the surface of the vibration generator has a first end and a second end opposite to the first end;
the vibration generator has an area of vibration source for generating vibration;
the surface of the vibration generator between the first end and the second end is flat and overlaps the area of vibration source;
compared to the first end, the second end is closer to one side of the display module;
a first distance is between the first end of the surface of the vibration generator and the rear surface of the display module;
a second distance is between the second end of the surface of the vibration generator and the rear surface of the display module; and
the second distance is greater than the first distance;
wherein the vibration generator comprises:
a module frame in the structure;
a bobbin on the module frame; and
a protection member at an upper portion of the bobbin; and

wherein the surface of the vibration generator is a surface of the protection member.
