Description

an electronic photo album

technical field

The invention relates to the field of household appliances, and more specifically, relates to an electronic photo album.

Background technique

The pictures that people take with cameras or mobile phones are often developed into photos and placed on photo frames, albums or other places, so that the photos in the photo frame or album are easy to watch and not easy to lose. The pictures in the mobile phone or camera are easy to be deleted, and some pictures that people like are hard to get back once deleted, so people will wash their favorite pictures into photos and put them in the album or on the photo frame, so that they don’t have to worry about the photos. The question will be deleted. However, we know that photos are generally large, and photo albums or photo frames are also large in size, and the photo album or photo frame has limited space for placing photos, so it is not easy to carry, and it is inconvenient to watch pictures anytime and anywhere.

I have designed an electronic photo album for storing pictures, including a display screen for displaying pictures, a casing, a circuit board and a battery fixed in the casing. The circuit board is bonded and fixed on the casing by double-sided adhesive tape, and the circuit board is provided with control keys for controlling the electronic photo album. This program is unpublished. When pressing the control key, because the circuit board is glued on the housing by double-sided adhesive tape, once people press too much, the fixing of the circuit board will be loosened, which is not convenient for the user to control the electronic photo album.
