Alternatively, the radius of the first corner and the radius of the second corner may be reasonably selected by the external dimensions of the housing 100 and the display module 200.

In another alternative embodiment, in the extending direction of the first edge of the first structural member 110, the first structural member 110 may be connected to the display module 200 by a plurality of connecting portions, the plurality of connecting portions are distributed at intervals, and the plurality of first sub slits 101 are located between the connecting portions. When electronic equipment transversely grips, the user palm covers the first sub-gap 101 of the edges and corners of electronic equipment easily, and at this moment, first sub-gap 101 sets up in the extending direction of first edge, and then makes the user palm be difficult to cover first sub-gap 101 to electronic equipment's audio transmission's reliability has been improved.

Further, the first sub slits 101 are arranged at a first edge along the length direction, which is a long edge of the first structural member 110, and the first sub slits 101 are located at a center position of the long edge. At this time, when the electronic apparatus is held in the lateral direction, the palm of the user's hand is less likely to cover the first sub slit 101, further improving the reliability of audio transmission of the electronic apparatus.
