Electronic device with wind speed detection function and wind speed detection method

A wind speed detection method for an electronic device includes detection of a first air pressure value in outside environment around the electronic device when an air hole of the electronic device is blocked. The electronic device can be aligned directly against a wind and a second air pressure value is detected in outside environment. A wind pressure value in the outside environment can be acquired according to a difference value between the first air pressure value and the second air pressure value. Value of wind speed in the outside environment can be established according to the wind pressure value and a relationship between the wind pressure value and the wind speed value.
