Abstract
The utility model discloses a novel sound velocity tester which belongs to the field of teaching experimental apparatus and comprises a base, wherein the base is provided with a liquid tank; two sides of the base are provided with columnar vertical rods between which a crossbar is arranged; two sides of the crossbar are provided with sleeves matched with the vertical rods; bolts are arranged on the sleeves; a sliding block is arranged on the crossbar; a testing transducer is connected under the sliding block; and the vertical rods are provided with height gauges, and the crossbar is provided with a levelling instrument. Compared with the prior art, the novel sound velocity tester has the advantages of being simple in operation, capable of testing the sound velocity of different mediums effectively, improving the testing result accuracy, and the like.
Description
Technical field
The utility model relates to a kind of teaching and experiment equipment, especially a kind of novel Sound velocity measuring apparatus, and that this analyzer has is time saving and energy saving, be easy to operation under different medium, improve characteristics such as testing precision.
Background technology
At present, the sound velocity determination experimental apparatus that uses in the acoustic experiment mainly comprises testing transducer, testing jig and liquid bath, wherein testing jig and liquid bath separate design, height and level interval all can not be regulated effectively, in the experimentation, when measuring in the liquid velocity of sound, need put liquid bath in the testing jig into earlier, when measuring THE VELOCITY OF SOUND IN AIR, need again liquid bath is taken out, waste time and energy, and when from liquid, take out measuring the airborne velocity of sound, fluid drips drops on desktop, stays the water mark easily.
The utility model content
Technical assignment of the present utility model is to provide a kind of novel Sound velocity measuring apparatus at above-mentioned deficiency of the prior art.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of novel Sound velocity measuring apparatus, comprise base, wherein, on base, be provided with liquid tank, be provided with the column vertical rod in the base both sides, be provided with cross bar between the column vertical rod, the cross bar both sides are provided with the sleeve pipe that is complementary with vertical rod, are provided with bolt on sleeve pipe, on cross bar, be provided with slide block, the slide block below is connected with testing transducer, is provided with height gauge in vertical rod, is provided with surveyor's staff on cross bar.
The beneficial effect that the utlity model has is:
1, simple in structure, easy to operate, can in different medium, measure the velocity of sound effectively.
2, be convenient to regulate height and level interval, time saving and energy saving, the accuracy that improves measurement result.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment
With reference to Figure of description the utility model is done following detailed description the in detail:
As shown in the figure, the utility model comprises base 1, on base 1, be fixed with liquid tank 2, be fixed with column vertical rod 3 in the both sides of base 1, cross bar 4 is housed between column vertical rod 3, be fixed with the sleeve pipe 5 that is complementary with column vertical rod 3 in the both sides of cross bar 4, bolt 6 is housed on sleeve pipe 5, be convenient to the position of fixed transverse rod 4 in column vertical rod 3 effectively, slide block 7 is installed on cross bar 4, and slide block 7 belows are connected with testing transducer 8, and height gauge 9 is arranged in column vertical rod 3, surveyor's staff 10 is arranged on cross bar 4, can improve the accuracy of measurement result effectively.
In the experimentation, when need measuring the airborne velocity of sound, regulate the height of cross bars 4, make testing transducer 8 place air,, measure the airborne velocity of sound then and get final product by the level interval that slide block 7 is regulated testing transducers 8 by bolt 6.
When needing to measure sound's velocity in liquid, regulate bolt 6, cross bar 4 is descended immerse fully in the liquid until testing transducer 8, regulate level interval then, the velocity of sound gets final product in the mensuration liquid.
