The test source of sound can write every mobile phone to be measured by software program, after foam is mounted, play test source of sound, Settable test source of sound will be automatically stopped broadcasting or loop play after finishing.After test source of sound broadcasting a period of time again Sound-recording function is opened, when mobile terminal sound-recording function identification is less than ambient sound, stops recording, system obtains recording text Part is preserved, and is further analyzed.Preferably, mobile phone can be positioned in closed chest and be recorded, the closed chest is tool Have a preferable soundproof effect, and be that transparent material is constituted, or have the chest of the monitor window being made up of transparent material, then or other Facilitate operating personnel's operating process and result with the closed chest of soundproof effect.The monitor window and transparent material are easy for behaviour Make personal observations' operating process and result, improve operating efficiency.
S202:The corresponding frequency values of primary peak are used as low-frequency resonant point in extracting the recording file of the mobile terminal.
S300:Whether the low-frequency resonant point is judged between value range, if judging that its is qualified, if not conforming to otherwise Lattice.
The corresponding frequency values of first crest are extracted in the recording file, it is as low-frequency resonant point, the low frequency is humorous Shake and a little compare with preset maximum and minimum value, if low-frequency resonant point is between maximum and minimum value, be judged as Certified products, conversely, being defective work, thus avoid defective work and dispatch from the factory.
Further, it is possible to will determine that result is displayed on the mobile terminal screen, display can be optional sign, letter Deng display format not limited to this.
It is described that qualified method is filled based on mobile terminal detection Horn/bubbler toy cotton patch, wherein, step is also included before the S100 S, the step S is specifically included:
S1:Choose with maximum low frequency resonance point first and second refer to machine with reference to machine and with minimum low-frequency resonant point value;
Two batches mobile phone is chosen, the low-frequency resonant point of the loudspeaker of two batches mobile phone is respectively maximum and minimum in the margin of tolerance Value, is respectively by hand mounted onto two batches mobile phone foam by structure expert, and by professional audio equipment, test this two batches mobile phone Loudspeaker performance, choose the hand with low-frequency resonant point maximum and minimum value that performance best suits specification respectively from every batch Each one of machine, respectively first refers to machine with reference to machine and second.
S2:With described first test source of sound is played respectively with reference to machine with reference to machine and described second, it is synchronous to open the first reference Machine and described second refers to machine sound-recording function, and saves as the first recording file and the second recording file respectively;
Two with reference to placing test sources of sound in machines, and will be respectively placed in quiet environment with reference to machine and play out, synchronous to open The sound-recording function of the reference machine, sound recording is got off.Save as the first recording file and the second recording file respectively again.
S3:The corresponding frequency values of primary peak are used as the first low-frequency resonant point in extracting first recording file, and carry The corresponding frequency values of primary peak are used as the second low-frequency resonant point in taking second recording file.
The corresponding frequency values of first crest, i.e. low-frequency resonant point in two parts of recording files are extracted, as subsequent detection loudspeaker Foam attachment whether qualified reference value, wherein, first with reference to machine the corresponding first low-frequency resonant point of the first recording file, The corresponding second low-frequency resonant point of second recording file of the second reference machine.
In sum, detection Horn/bubbler toy cotton patch provided by the present invention fills qualified method and system, and methods described is pre- first If for judge Horn/bubbler toy cotton patch dress whether the maximum and minimum value of qualified mobile terminal low-frequency resonant point;Then by record Sound, and extract the low-frequency resonant point of the primary peak corresponding frequency values acquisition mobile terminal in recording file;Finally judge Whether the low-frequency resonant point is between maximum and minimum value, if judging that its is qualified, if otherwise unqualified.So as to this hair Bright one side can be quick, efficiently filters out the underproof product of attachment, it is to avoid substandard product dispatches from the factory, and improves product entirety Quality, and ensure mobile phone tonequality, be conducive to improving product percent of pass, it is ensured that product quality, another aspect is the present invention detect into This is relatively fewer, and operation is easier to, and detection time is also relatively short, relatively low to operating personnel's professional knowledge, so Being capable of the cost of an asset that less input and time cost.
