The MIC service qualities detection of mobile phone is that mobile phone flows to one of important step before market, has completed the mobile phone of assembling Last pass of MIC detection in mobile phone production line.The process that this passage product examine is surveyed is at present mostly by being accomplished manually, still Unrealized automation.Artificial detection can bring problems with:1st, the production efficiency of artificial detection influence mobile phone;2nd, artificial detection production Raw False Rate is high;3rd, artificial detection band carrys out higher human cost.
Utility model content
In order to overcome the above not enough, the utility model proposes a kind of mobile phone MIC detection means exported based on flat mouth.This The external voice signal that device gathers mobile phone MIC is believed through A/D conversions and enhanced processing and being exported by flat mouth to PC ends The processing of breath and parameter compare analysis.The utility model solves artificial detection and brings high cost, poor efficiency, high error rate A series of problems, such as with production line is unfavorable for, especially for the serial mobile phones of iphone of flat mouth audio output.
The utility model solves the technical scheme that its technical problem used:The mobile phone MIC detection means of flat mouth output Including sound proof box, audio player, mobile phone MIC, flat mouth audio output receiving terminal, signal A/D modular converter, digital microprocessor And power supply, it is characterised in that:
Tested mobile phone is placed in the sound proof box, the mobile phone MIC is in sound insulation detection environment;
Audio player is also placed with the sound proof box, for providing fixed-audio input to the mobile phone MIC;
The flat mouth audio output is electrically connected with the mobile phone MIC, for by the mobile phone MIC audio players gathered Audio signal is converted into electric signal and exported;
The signal A/D modular converter is electrically connected with the flat mouth audio output, for output analog electrical signal to be turned Turn to data signal;
The digital microprocessor is electrically connected with signal A/D modular converter.
Further, the digital microprocessor includes digital signal processing module and LCD display module;
Further, the signal that digital signal processing module is used to input signal A/D modular converter is handled, and with The mutual com-parison and analysis in built-in audio source of audio player plays, LCD display module exports analysis result, is allowed to more straight See, be easy to workman to detect.
Further, the mobile phone MIC is the microphone apparatus of tested mobile phone.
Further, the power supply is that whole detection means is powered.
Further, the power supply 7 is that whole detection means is powered.
The utility model has the following advantages compared with prior art:
The utility model solve mobile phone dispatch from the factory MIC manually detect inefficient, the high cost brought, it is low precision, unfavorable The problems such as streamlined is produced.And for the mobile phone MIC detections of novel flat mouthful audio output, realize high accuracy, high efficiency, it is low into This mobile phone MIC detections.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made The every other embodiment obtained, belongs to the scope of the utility model protection.
Fig. 1 show the structure chart of the mobile phone MIC detection means exported based on flat mouth.
The mobile phone MIC detection means exported based on flat mouth can be divided into two parts, and a part is played by sound proof box 1, audio Device 2, the signal acquisition part of mobile phone MIC3 compositions;Another part is by flat mouth audio output receiving terminal 4, signal A/D modular converter 5, digital microprocessor 6(Including digital signal processing module 8 and LCD display module 9)The Audio Signal Processing part of composition.
Sound proof box 1 is used for the influence for completely cutting off the audio process that outside noise gathers audio player 2 to mobile phone MIC3 first, Mobile phone is connected using flat mouth audio output line with flat mouth audio output receiving terminal 4;
The audio frequency simulation electric signal that signal A/D modular converter 5 will be fed into carries out programming amplifying, anti-aliasing filter and voltage After lifting, it is allowed to be converted into data signal through over-sampling-quantization-coding etc., the master chip of signal A/D modular converter 5 is used TLC320AD50C chips.TLC320AD50C be one kind 16 of TI companies production, audiorange (sample frequency for 2~ 22.05kHz), the analog interface circuit of frequency overlapped-resistable filter and reconfigurable filter is included, it has can be connected with many DSP same Walk serial communication interface.Also include timer (adjustment sample rate and frame synchronization delay) in TLC320AD50C and controller (is adjusted Reorganize journey gain amplifier, phaselocked loop, master slave mode).
Digital microprocessor 6 will be carried out using digital signal processing module 8 after Digital Signal Processing with built-in audio signal Comparative analysis is gone forward side by side line distortion analysis, and result is shown by LCD display module 9.Digital signal processing module 8 is used Based on the ARM Cortex-M3 processors STM32F103VBT6 of 32 as main control chip, it has very abundant piece domestic-investment Source, such as real-time clock (RTC), timer (TIM), general purpose I/O Interface (GPIO), dma controller, A/D converter, USART Interface, I2C interfaces, SPI interface and CAN interface also include 20 KB on-chip SRAM, 128 KB in-chip FLASH and Full speed USB peripheral device of one support specification of USB 2.0 etc., it is the main control unit of whole system, coordinates other modules complete Into multiple functions such as data acquisition, storage, processing, control, transmission.
