1. An electronic device, comprising:
a housing (100), provided with an opening and a positioning groove (110);
a functional device (200), movably mounted on the housing (100);
a driving mechanism (300), mounted in the housing (100) and comprising a piezoelectric device (310), wherein the piezoelectric device (310) vibrates when being energized; and
a transmission mechanism (400), comprising a cam (410), a connection portion (440) and a positioning portion (450), wherein the functional device is connected to one end of the connection portion (440), and the other end of the connection portion (440) is configured to engage with the cam (410), the positioning portion (450) is hingedly connected to the connection portion (440), the positioning portion (450) comprises a positioning hook (451), the cam (410) is disposed at an inner side of the functional device (200), the cam (410) comprises a wheel body (411) and a protruding portion (412), the protruding portion (412) is disposed at a wheel rim of the wheel body (411), the wheel body (411) is mounted on the piezoelectric device (310), and the piezoelectric device (310) drives the cam (410) to rotate between a first location and a second location;
wherein in a case that the cam (410) is at the first location, the functional device (200) is located in the housing (100), and in a case that the cam (410) is at the second location, the protruding portion (412) drives at least part of the functional device (200) to extend out of the housing (100) from the opening, and the positioning hook (451) is engaged with the positioning groove (110) in a limiting manner to limit the functional device (200) to retract into the housing (100) from the opening.
