Biological characteristic information detection device and electronic device

An electronic device, comprising:

• a shell;
• a biological characteristic information detection device, the biological characteristic information detection device being at least partially arranged in the shell;
• and
• a main board arranged in the shell and electrically connected to the biological characteristic information detection device;
• wherein the detection device comprises:
• a pressure detection module comprising a cantilever beam and a pressure sensor, wherein the pressure sensor is fixed on a surface of the cantilever beam, the cantilever beam comprises an elastic arm and a fixed base, the fixed base is fixed in the electronic device, and the elastic arm is suspended in the air;
• and
• a photoplethysmography (PPG) detection module arranged on the elastic arm and configured to detect a PPG signal of a user when the user presses the electronic device,
• wherein when the user presses the electronic device, a pressure signal applied to the electronic device by the user is transmitted to the cantilever beam through the PPG detection module, so that the pressure sensor detects the pressure signal, and the pressure signal and the PPG signal are used to detect biological characteristic information of the user.
