Abstract
The invention discloses a cellphone motor vibration testing method, and the method comprises the steps: starting a cellphone motor and enabling the motor to start to work; picking up a motor vibration signal through a cellphone microphone, and converting the motor vibration signal into an electric signal; carrying out the spectral analysis of the electric signal collected by the microphone through an FFT algorithm, comparing the information of electric signal with a normal motor spectral information, and judging whether a test motor is working normally or not. Because the microphone of the cellphone is employed as a signal collection tool and the microphone and the vibration motor are disposed in a cavity of the cellphone, the method can pick up the motor vibration signal more effectively, greatly improves the anti-interference capability, carries out the spectral analysis of the data through the FFT algorithm, analyzes and judges the quality of the vibration function of the motor through analyzing and quantifying the specific indexes of the motor vibration: main frequency point, main frequency amplitude and noise amplitude, is more accurate and reliable in testing result, greatly simplifies the needed clamping tool and equipment, and reduces the testing cost.
Description
Technical field
The present invention relates to a kind of improved technology of motor for cell phone method for testing vibration.
Background technology
Traditional handset production line test motor vibrations use manual testing, do not have the index of any quantization, completely
Judge whether non-defective unit by manually.In order to the quantization for realizing motor vibrations is tested, prevent anthropic factor, have on market using logical
The mode for crossing external sensor receives motor vibrations signal, then carries out data analysiss by software, and quantification of targets is judged whether
Non-defective unit.But, because being external sensor, pickoff signals are unstable, easily affected by external environmental interference for the method, and increase
Hardware input cost, detection circuit are also more complicated.
The content of the invention
It is an object of the invention to provide a kind of test accurately and reliably motor for cell phone method for testing vibration.
In order to reach the effect above, the present invention is adopted the following technical scheme that：
A kind of motor for cell phone method for testing vibration, the method include：
Start motor for cell phone, make motor start working；
Motor vibration signal is picked up by mobile phone miaow head, and motor vibration signal is converted to into the signal of telecommunication；
Spectrum analyses are carried out by fft algorithm to the signal of telecommunication that miaow head is gathered, and is contrasted with normal motor spectrum information, sentenced
Whether disconnected institute's test motor is working properly.
Wherein, described spectrum analyses include dominant frequency frequency, dominant frequency amplitude and the noise amplitude of tested motor vibrations
Data.
The present invention as the miaow head using mobile phone itself is used as signals collecting instrument, with vibrating motor all in mobile phone cavity
Portion, can more effectively pick up motor vibrations signal, and anti-interference is greatly enhanced, and carries out spectrum analyses to data by fft algorithm,
By analyzing the specific index such as dominant frequency frequency, dominant frequency amplitude and noise amplitude of motor vibrations, by quantifying index analysis
Judge the quality of motor vibrations function, test result more accurately and reliably, while the hardware such as required clamp tool and equipment is significantly simple
Change, reduce testing cost.
Specific embodiment
The present invention is described in further detail below in conjunction with specific embodiment.
The motor for cell phone method for testing vibration that the present embodiment is disclosed compared with existing method of testing need not be set up other and shake
Dynamic sensor, signals collecting are more accurate, and specifically, the motor for cell phone method for testing vibration includes：
First, start motor for cell phone, make motor start work.After starter motor, if motor does not have normal vibration, then it represents that should
There is exception in motor for cell phone, if normal vibration, carries out next step and further analyzes.
After motor starts vibrations, motor vibration signal is picked up by the miaow head of mobile phone, and motor vibration signal is turned
It is changed to the signal of telecommunication；
Pass through fft algorithm again（The fast algorithm of discrete fourier transform）Spectrum analyses are carried out to the signal of telecommunication of miaow head collection, is analyzed
The specific index such as the dominant frequency frequency of motor vibrations, dominant frequency amplitude and noise amplitude, and carry out with normal motor spectrum information
Contrast, judges whether institute's test motor is working properly.If a certain index is not within the scope of normal motor spectrum information, table
Show the motor exception.
The present invention judges the quality of motor vibrations function by quantifying index analysis, test result more accurately and reliably, while
Clamp tool and equipment are greatly simplified, and reduce testing cost.
In the above-described embodiments, for the technologies such as fft algorithm, Spectrum Analysis Comparison are prior art, therefore not to repeat here.
Above-described embodiment is only the present invention preferably implementation, and indefiniteness is exhaustive, for being familiar with the art
Personnel for any obvious replacement, modifications and variations should all belong within the claims in the present invention protection domain.
