In one of the embodiments of the present application, referring to FIGS. 1 and 3, the side of the first hemispherical shell 11 away from the second hemispherical shell 12 is a flat surface, eliminating the arc structure on the side of the first hemispherical shell 11. The imaging hole 116, the speaker hole 117, the infrared hole 1110 and the light sensing hole 1120 are all provided on the flat surface. The internal space of the above-mentioned arc structure cannot be used, and the direct processing into a flat surface can further reduce the volume of the camera.

Optionally, referring to FIG. 9, the surface of the flat surface is covered with an infrared transparent filter 7, and the infrared transparent filter 7 is black to shield the infrared lampshade 113 to make the appearance of the camera more beautiful. Moreover, the infrared transparent filter 7 is provided with a first through hole 71 directly opposite to the infrared hole 1110, a second through hole 72 directly opposite to the light sensing hole 1120 is opened, and a second through hole 72 directly opposite to the camera 3 is opened. Three-through hole 73. The infrared-transmitting filter 7 is provided with a positioning pillar 74 protruding from the side facing the flat surface, and positioning holes are opened on the flat surface. The positioning pillars 74 cooperate with the positioning holes to facilitate the installation and positioning of the infrared-transmitting filter 7.

The above descriptions are only the preferred embodiments of this application and are not intended to limit this application. Any modification, equivalent replacement and improvement made within the spirit and principle of this application shall be included in the protection of this application. Within range.
