The embodiment of the invention makes the vibrating diaphragm of voicefrequency circuit produce amplitude by the induction present speed, and obtains corresponding level according to amplitude, by the corresponding relation of level and speed, thereby obtains present speed.
As shown in Figure 1, the method flow diagram for embodiment of the invention measuring speed comprises:
S101, the induction present speed also causes the vibration of Mike's voicefrequency circuit vibrating diaphragm, produces amplitude.
In embodiments of the present invention, when because of wind speed or mobile object motion, the extraneous current rate when Mike's voicefrequency circuit will detect because of wind speed or moving object campaign, and sense wind-force, thereby cause the vibrating diaphragm vibration of Mike's voicefrequency circuit, because the vibration of vibrating diaphragm produces corresponding amplitude.
S103 obtains current level based on described amplitude.
When vibrating diaphragm produces amplitude, the vibrating diaphragm and the distance between the backplane of Mike's voicefrequency circuit will change, owing to form between amplitude and the backplane with backplane and vibrating diaphragm dielectric capacitor as two electrodes, so variation of backplane and vibrating diaphragm distance, changed the electric capacity of capacitor, the change of electric capacity makes the output terminal of capacitor produce corresponding level.
S105 obtains present speed according to the corresponding relation of current level and speed.
In embodiments of the present invention, can detect by Mike's voicefrequency circuit being done different wind speed in the laboratory, obtain corresponding under different wind conditions speed and the corresponding relation of level, then, with corresponding correspondence setting in corresponding velocity measuring device, thereby realize obtaining present speed according to the corresponding relation of current level and speed.
Need to prove, in embodiments of the present invention, present speed can be current wind speed, it also can be the movement velocity of moving object, and, the wind speed of measuring or the movement velocity of moving object can be given user prompt by the mode of literal demonstration or auditory tone cues, thereby make things convenient for the user to know the current wind speed or the movement velocity of moving object.
The embodiment of the invention makes the vibrating diaphragm of voicefrequency circuit produce amplitude by the induction present speed, and obtain corresponding level according to amplitude, by the corresponding relation of level and speed, thereby obtain present speed, make the user can obtain the speed or the wind speed of current moving object easily.
As shown in Figure 2, the device synoptic diagram for embodiment of the invention measuring speed comprises:
Mike's voicefrequency circuit 21, be used to respond to present speed and produce amplitude, wherein, the extraneous current rate when Mike's voicefrequency circuit will detect because of wind speed or moving object campaign, thereby and sense the vibration that wind-force causes Mike's voicefrequency circuit vibrating diaphragm, thereby produce amplitude.
For further understanding the principle of work that Mike's voicefrequency circuit 21 is used for measuring speed, as shown in Figure 3, be the synoptic diagram of embodiment of the invention Mike voicefrequency circuit.Wherein, comprise
