A plurality of sound pick-up holes are formed at the left upper part of an excitation plate, a flat plate is embedded at the right upper part of the excitation plate, the excitation plate is connected with a pressure plate through two pull rods, a sound insulation hood is installed inside, a sound insulation layer is mounted between the sound insulation hood and the excitation plate, small holes with the same diameters and the same number as the sound pick-up holes are respectively formed in the position of the sound insulation layer corresponding to the excitation plate, a microphone is installed on a microphone installing rack through a microphone fixing plate, an adjustable padis installed at the bottom of the microphone installing rack, clamping blocks with rubber pads are fixed around one end of the sound insulation hood adjacent to the excitation plate, the clamping blocks are fixed on a panel through a mounting rack, and a pressure release cushion is mounted between the mounting rack and the panel. The utility model shields the environmental noise and has good sound insulation effect; the sound pick-up device with simple structure is adopted for replacing the traditional manual detection device; and both the sound pick-up precision and the sound pick-up efficiency are improved.
Description
Technical field
The utility model relates to audio detection equipment, especially relates to a kind of self-screened exciting pick-up integrated device that is used for audio detection.
Background technology
The audio detection method is a kind of online test method of the workpiece inherent vice being carried out Non-Destructive Testing.And the generation of sound and to pick up be important step in the testing process.At present, the pickup process of domestic workpiece inherent vice audio detection mostly is manually-operated, promptly discerns inherent vice by the sound that knocks the workpiece generation.There is following some shortcoming in the manual detection method: (1) testing staff's working strength is bigger, and automaticity is low, and efficiency of measurement is low; (2) interference from human factor is big, and pickup effect is poor; (3) ambient noise interference is serious.
Summary of the invention
The purpose of this utility model is to provide a kind of self-screened exciting pick-up integrated device that is used for audio detection, adopts totally enclosed structure that sound is produced and picks up, and has replaced the method for manual detection.
The technical scheme that its technical matters that solves the utility model adopts is:
Have a plurality of pickups hole on exciting plate upper left side, the upper right side embeds dull and stereotyped, connect with two pull bars between exciting plate and the pressing plate, in blimp is housed, mount pugging between blimp and the exciting plate, pugging has aperture with pickup hole same diameter and same number at the exciting Board position of correspondence, microphone is installed on the microphone erecting frame by the microphone fixing plate, adjusting pad is equipped with in microphone erecting frame bottom, blimp is near the clamp that is fixed with the band rubber gasket around excitation plate one end, clamp is fixed on the panel by erecting frame, mounts the decompression pad between erecting frame and the panel.
The utility model is compared with background technology, and the useful effect that has is:
1, shielded neighbourhood noise, soundproof effect is good.
2, adopt sound pick up equipment simple in structure to replace traditional manual detection device, improved pickup precision and efficient.
Description of drawings
Fig. 1 is a structural principle synoptic diagram of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1. pressing plate, 2. adjusting pad, 3. microphone erecting frame, 4. microphone fixing plate, 5. pull bar, 6. decompression pad, 7. pugging, 8. microphone, 9. clamp, 10. exciting plate, 11. erecting frames, 12. blimp, 13. pickup holes, 14. panels, 15. flat boards, 16. apertures.
Embodiment
As depicted in figs. 1 and 2, of the present utility modelly have a plurality of pickups hole 13 on exciting plate 10 upper left sides, it is dull and stereotyped 15 that the upper right side embeds, and dull and stereotyped 15 adopt special substances, can change flat board 15 according to workpiece, the noise of eliminating workpiece and dull and stereotyped 15 bump generations helps to obtain more effective excitation sound source.Connect with two pull bars 5 between exciting plate 10 and the pressing plate 1, in blimp 12 is housed, blimp 12 has been realized the isolation fully of sound collection mechanism and external environment, has fit sealing preferably.Mount pugging 7 between blimp 12 and the exciting plate 10, effectively eliminate the noise that external environment causes, eliminate the vibration that exciting plate 10 causes.Pugging 7 has the aperture 16 with pickup hole 13 same diameter and same number in exciting plate 10 positions of correspondence, help voice signal to be sent in the sound collection mechanism.Microphone 8 is installed on the microphone erecting frame 3 by microphone fixing plate 4, and adjusting pad 2 is equipped with in microphone erecting frame 3 bottoms, can regulate microphone 8 height by adjusting pad 2, with the microphone 8 that adapts to different size.Blimp 12 is near the clamp 9 that is fixed with the band rubber gasket around excitation plate 10 1 ends, and clamp 9 is fixed on the panel by erecting frame 11, mounts decompression pad 6 between erecting frame 11 and the panel 14.Decompression pad 6 is eliminated the vibration that panel 14 causes.Can change excitation plate 10 according to the characteristic of detected workpiece.Fastening with the pull bar 5 that rubber blanket is housed, can avoid the accuracy of exciting plate 10 vibration interference sound collection mechanisms.
Described blimp 12 is blimps of a monoblock sound-proof material.
Embodiment of the present utility model is as follows:
Before the experiment beginning, exciting plate 10 is fastening by pull bar 5 and pressing plate 1 that rubber blanket is housed with blimp 12, with clamp 9 blimp 12 and erecting frame 11 is fixed together, and available adjusting pad 2 is adjusted the position of microphone erecting frame 3, to adapt to different microphones.Encourage pick-up integrated device to be fixed on the panel 14 self-shielding type by erecting frame 11.During the experiment beginning, workpiece falls from the self-screened exciting pick-up integrated device top, with exciting plate 10 bumps, the voice signal that bump produces imports in the blimp 12 by pickup hole 13, gathered by microphone 8, reach the purpose of pickup, the voice signal that picks up imports to processing module and handles.
Above-mentioned embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
