Resumen
Tetrahedral lectern to hold electronic devices and their use as advertising support. The present invention is a stable lectern for holding electronic devices, such as mobile phones, tablets or the like, which allows positioning them with a certain inclination. The lectern is formed from a single piece of semirigid material such as cardboard, paper, plastic or the like, which folds and fits easily in a way that takes on a tetrahedral shape. The visible faces of the lectern can contain publicity so the lectern can also be used as an advertising medium. (Machine-translation by Google Translate, not legally binding)
