Abstract: Disclosed is a method and device for testing wind speed. The method includes, but is not limited to: measuring a static pressure P0 of an inner cavity of a pressure hole of a mobile device (S100), wherein the pressure hole being in communication with the outside; aligning the pressure hole to a wind direction and acquiring a total pressure P of the wind (S101); and acquiring a current wind speed according to a corresponding relational expression between a wind speed v and a dynamic pressure P−P0 (S102). The device includes, but is not limited to, a pressure sensor and a wind speed acquiring unit. The technical solution acquires the current wind speed according to a correspondence between wind speeds and dynamic pressures of wind, may effectively improve the precision of the wind speed testing, and does not cause damage to relevant parts of the mobile device.

Abstract: The present application discloses a method and apparatus for testing vital capacity. The method comprises: measuring a static pressure P0 of a pressure hole inner cavity of a mobile device; wherein the pressure hole is communication with the exterior and is purposely disposed on the mobile device or is an already-designed opening; obtaining an air pressure P(t) at each moment by blowing air towards the pressure hole; obtaining an air flow speed v(t) corresponding to each moment according to a correspondence relation formula between the air flow speed v(t) and a pressure differential P(t)−P0; and obtaining vital capacity Vc of the subject according to a correspondence relationship between a measurement time t and the air flow speed v(t).
