Abstract

The invention discloses a sound amplifying mobile phone shell suitable for a public environment and relates to the field of mobile phone peripherals. The mobile phone shell comprises a mobile phone shell body, a sound amplifying plate, a large supporting plate, a u-shaped bolt groove, a bolt and a locking mechanism, wherein the large supporting plate is rotatably connected to the back face of themobile phone shell body through a rotating shaft, and the sound amplifying plate is rotatably connected to a sound amplifying plate rotating center groove in the large supporting plate. The sound amplifying plate and the large supporting plate which can slide in and out are convenient to switch and small in size. When the mobile phone shell is used, the sound amplifying plate slides out, can rebound sound towards the face of a user, enables the user to hear larger sound, and the sound amplifying plate slides in and clings to the back of the mobile phone shell when not in use, and cannot influence the use of a mobile phone.
