Abstract: An electronic device including a protection layer, a display panel, and a sound broadcasting element is provided. The protection layer has an inner surface and a side surface directly connected to the inner surface. The display panel is disposed on the inner surface of the protection layer and has a back surface and a side surface directly connected to the back surface. The sound broadcasting element is located adjacent to the side surface of the display panel, and the sound broadcasting element includes a piezoelectric component and a connection component.

Abstract: An electronic device has a narrow viewing angle state and a wide viewing angle state, and includes a panel and a light source providing a light passing through the panel. In the narrow viewing angle state, the light has a first relative light intensity and a second relative light intensity. The first relative light intensity is the strongest light intensity, the second relative light intensity is 50% of the strongest light intensity, the first relative light intensity corresponds to an angle of 0°, the second relative light intensity corresponds to a half-value angle, and the half-value angle is between ?15° and 15°. In the narrow angle state, a third relative light intensity at each angle between 20° and 60° or each angle between ?20° and ?60° is lower than 20% of the strongest light intensity.

Abstract: A shower curtain rod contains: multiple coupling posts and multiple rotatable connection assemblies. A respective one rotatable connection assembly includes: a first connector, a second connector, a flexible seat, and a fixing bolt. The first connector has a first locating portion and a first rotatable joining portion. The first rotatable joining portion has a through hole and multiple notches. The second connector has a second locating portion and a second rotatable joining portion. The second rotatable joining portion has two opposite tabs and an accommodation groove. The flexible seat is received in the accommodation groove and includes a sole plate and two side plates. A respective one side plate has a passing aperture, a positioning protrusion, and at least one elastic sheet. The fixing bolt is configured to rotatably connect the first rotatable joining portion in the trench between the two side plates.
