Embodiment Construction

[0024] In the embodiment of the present invention, the vibrating membrane of the audio circuit generates an amplitude by sensing the current speed, and obtains the corresponding level according to the amplitude, and obtains the current speed through the corresponding relationship between the level and the speed.

[0025] Such as figure 1 As shown, it is a flow chart of a method for measuring speed in an embodiment of the present invention, including:

[0026] S101, sensing the current speed and causing the diaphragm of the microphone audio circuit to vibrate to generate an amplitude.

[0027] In the embodiment of the present invention, when the wind speed or the movement of the moving object, the microphone audio circuit will detect the external airflow strength due to the wind speed or the movement of the moving object, and sense the wind force, which will cause the diaphragm of the microphone audio circuit to vibrate. The vibration of the diaphragm produces a corresponding ...

Abstract

The embodiment of the present invention relates to a method of measuring speed, a device and a mobile terminal thereof. The method of measuring the speed comprises sensing the current speed and causing the vibration of the vibrating diaphragm of the microphone audio circuit so as to generate amplitude, acquiring the current level based on the amplitude, and acquiring the current speed according to the corresponding relation between the current level and the speed. Simultaneously, the embodiment also provides a device and a mobile terminal, which are used for measuring the speed. The embodiment adopts the amplitude generated by the vibrating diaphragm of the microphone audio circuit to acquire the current speed, so that the user can conveniently acquire the speed or the wind speed of the current moving object. Simultaneously, the embodiment provides a speed measuring function at the mobile terminal, and thus the mobile terminal has a novel function and application, enriching the experience of the user.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and device for measuring speed and a mobile terminal thereof. Background technique [0002] The popularization of mobile terminals and the diversification of electronic products have promoted the diversification of mobile terminal functions. Today, a mobile terminal can integrate communication tools, radio, MP3, camera and other functions into one, which can greatly meet user needs and provide users with different experiences. [0003] In the existing environment, if you need to measure the speed or wind speed of a moving object, you mainly rely on professional equipment such as radar speed measurement or other speed measuring instruments, but for ordinary users, these professional equipment are usually not available. If you want to know the current speed of a moving object Or wind speed, for ordinary users, there are certain difficulties. In general, ordi...
