Abstract
The invention discloses a sound test device used in the production field. It includes the sampling device, detection device, display, the bar code scanner, the mouse, the keyboard, the sound signal transmission line. The sampling and detection devices are two separately monomers, which are connected with each other by the sound signal transmission line. The sampling device is composed by the screening box, the manual ear and the tested piece installing frame. The detection device is made up of the aural signal analyzer and industrial computer. The invention also provided a test method for the sound test device. The invention can not only test the sound in the production field, but test the every sound index for the production according to the current standard and custom need; also it can avoid the noise influence from production line to assure the test reliable.
Description
Technical field
The present invention relates to the manufacturing production scene of consumer electronics product field tests, be specifically related to the equipment that is applicable to the production scene acoustical testing and the method for testing of audio class electronic product.
Background technology
Though existing testing laboratory method of testing can be measured every sound index, can't use in the production scene more accurately.Current audio class consumer electronics manufacturing enterprise mainly adopts two kinds of technology to the production scene test of sound: the one, and adopt artificial method to judge; Two are to use microphone to carry out the sound test.
More than two kinds of method of testings mainly have following defective:
1. the manual method subjectivity is very big, is unfavorable for production control;
2. having or not of sound can only be measured, the quality height of sound can't be measured;
3. can't be to other indexs of sound, for example the harmonic component size is analyzed;
4. can't eliminate of the influence of production line noise to test.
Summary of the invention
The object of the present invention is to provide a kind of method that is applicable to the acoustic test equipment and the acoustical testing of consumer electronics product production scene.
Technical solution of the present invention is as follows:
The acoustic test equipment that is applicable to the production scene comprises sampling apparatus, pick-up unit, display, barcode scanner, mouse and keyboard, transmission of sound signals line, it is characterized in that: sampling apparatus and pick-up unit are independently monomers of two difference, connect with the transmission of sound signals line between sampling apparatus and the pick-up unit, sampling apparatus is made up of shielded box, artitificial ear, measured piece erecting frame, artitificial ear, measured piece erecting frame are positioned at shielded box, and pick-up unit is made up of audio signal analysis instrument and industrial computer.
The method of above-mentioned acoustical testing is carried out as follows:
A. by mouse and keyboard input instruction, test process begins;
B. use barcode scanner that the sequence number of measured piece is read in the industrial computer in the pick-up unit;
C. measured piece is put on the measured piece erecting frame;
D. the door with shielded box bars up, and prevents the interference of noise of production line;
E. make measured piece work and sound, artitificial ear with the sound signal data that collects by analyzing in the transmission of sound signals line input detection device;
F. the audio signal analysis instrument in the pick-up unit is handled the result and the data transmission of acoustical testing to industrial computer, and test result and data are shown on display;
G. by mouse and keyboard input instruction, finish test or carry out the test of next product.
Utilization the present invention carries out the acoustical testing of production scene, not only can having or not at production scene test products sound, and can carry out the test of every acoustics index to product according to general standard and client's demand, and can also avoid the production line The noise effectively, guarantee the reliability of test.
Description of drawings
Accompanying drawing 1 is applicable to the synoptic diagram of production scene acoustic test equipment for the present invention.
Embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, the acoustic test equipment that is applicable to the production scene comprises sampling apparatus, proving installation 4, display 1, barcode scanner 2, mouse and keyboard 3, transmission of sound signals line 9, sampling apparatus comprises shielded box 5, artitificial ear 6, measured piece erecting frame 8, proving installation 4 is made up of audio signal analysis instrument and industrial computer, artitificial ear 6, measured piece 7 are positioned in 5 li of shielded boxes, sampling apparatus and proving installation are independently monomers of two difference, connect with the transmission of sound signals line between sampling apparatus and the pick-up unit.
The present invention is applicable to that the method for testing of production scene acoustic test equipment carries out as follows:
A. by mouse and keyboard 3 input instructions, test process begins.
B. use barcode scanner 2 that the sequence number of measured piece is read in the industrial computer in the pick-up unit 4.In order effectively to preserve test record and test result to be carried out statistical study, each electronic product all can have a unique sequence number, and this sequence number is attached to the eye-catching position of product with the form of the label of bar code.Before test beginning, production line requires with barcode scanner 2 this sequence number to be read in, and this sequence number part of file as a result of, is beneficial to the tracking to test data.
C. measured piece 7 is put on the measured piece erecting frame 8.
D. the door with shielded box 5 bars up, and prevents the interference of noise of production line.The physical dimension of the shielded box that adopts in the present embodiment is centimetre (height) * 60,80 centimetres of (wide) * 85 centimetre (deeply), thick 8 centimetres of wall, and soundproof effect is fine, can well simulate the quiet environment of similar quiet room.
E. make measured piece 7 work and sound, artitificial ear 6 is gathered voice data and by transmission of sound signals line 9 the audio signal analysis instrument in the data input detection device 4 is analyzed, artitificial ear is according to the ecological principle of human body, the physiological status of anthropomorphic dummy's ear listening is gathered useful voice signal, and have stopping direct current, filtering, enlarging function, to analyze through the data-signal input audio analyzer of conditioning, thereby every acoustics index is measured, that not only can measure sound has or not and size the quality quality of going back energy measurement sound.
F. the audio signal analysis instrument in the pick-up unit 4 handles to the industrial computer in the pick-up unit 4 result and the data transmission of acoustical testing, and test result and data are shown in display 1.
G. by mouse and keyboard 3 input instructions, finish test or carry out the test of next product.
