Abstract
The utility model relates to a test method of multi-model acoustic devices, which has the following steps: building a alterable test cavity body; providing different lids arranged according to samples which need to be measured of different types; covering the alterable test cavity body with the lid loading the sample which needs to be measured to form sealed space with the sample, the lid and the alterable test cavity body; testing the sample. The alterable test cavity body is provided with a hollow cavity body part, several cavity body rings connected with the cavity body part and a piston which can be inserted in the cavity body part and the cavity body ring. The utility model only needs to replace different lids and change the volume of the alterable test cavity body by selecting the cavity body ring with corresponding volume according to samples which need to be measured of different types to test the performance parameter of multi-model acoustic devices , which not only reduces the production cost but also improves the availability of resources.
Description
[technical field]
The present invention relates to a kind of method of testing, relate in particular to a kind of method of testing of polytypic acoustical device.
[background technology]
The method of testing of relevant acoustical device is that testing sample (acoustical device) is placed in the test cavity, thus every performance index of test testing sample.Described test cavity is the semiclosed body of a hollow, and it has fixing volume and is provided with the cavity hatch of carrying testing sample, when with testing sample as for cavity hatch on the time, testing sample and whole test chamber body form confined space.
Be the performance of test testing sample, the sample of common a kind of model needs the different cavity to be measured of some volumes to satisfy the test needs.The test cavity of correlation technique has fixing volume, and its cavity hatch can only be tested a kind of sample of model.Sample for a kind of model of test then needs a large amount of cavitys like this, and this method of testing certainly will improve production cost of products.And when measuring the sample of different model, because the sample structure difference of each model, test cavity can not get utilizing again the serious waste resources of production in the past.
Therefore, be necessary to provide a kind of new method of testing to overcome above-mentioned shortcoming.
[summary of the invention]
The object of the present invention is to provide a kind of method of testing that reduces cost, effectively utilizes the polytypic acoustical device of the resources of production.
The concrete steps of the method for testing of polytypic acoustical device of the present invention are as follows: set up a variable-metric cavity; Different lid at the testing sample setting of different model is provided; The lid lid that is loaded with testing sample is connected on the variable-metric cavity, makes described testing sample, lid and variable-metric cavity form confined space; Testing sample is measured.Described variable-metric cavity be provided with a hollow cavity portion, connection chamber body some cavity rings and can be inserted in cavity portion and the cavity ring in piston.
Compared with prior art, the present invention has the following advantages: the volume that only need change different lids and change variable-metric cavity at the testing sample of different model, promptly select the cavity ring of corresponding volume, just can measure the performance parameter of the acoustical device of multiple model.Not only reduce production cost, and improved resource utilization.
[description of drawings]
Fig. 1 is for being connected to the variable three-dimensional stereographic map of testing cavity with the present invention with the lid lid.
Fig. 2 on lid shown in Figure 1 lid the is connected to variable three-dimensional test cavity time along the cut-open view of II-II.
[embodiment]
The method of testing of polytypic acoustical device of the present invention may further comprise the steps (described acoustical device claims testing sample again):
A. set up a variable-metric cavity 1;
B., the different lid 2 that is provided with at the testing sample of model (not shown) not is provided;
D. testing sample is measured.
Variable-metric cavity 1 be provided with hollow cavity portion 11, connection chamber body 11 some cavity rings 12 and can be inserted in cavity portion 11 and cavity ring 12 in piston 13.Wherein, the sidewall 15 that extends by diapire 14, from diapire 14 of cavity portion 11 and form from the cavity hatch 16 that sidewall 15 upper limbs extend.For guaranteeing that testing sample, lid 2 and variable-metric cavity 1 form confined space, the overall height of some cavity rings 13 must be less than the maximum height of piston 13 in 11 activities of cavity portion.
Described each lid 2 is provided with and is connected in the supporting part 21 of cavity hatch 16 and the sample placement section 22 of placement testing sample, and wherein, the supporting part 21 of each lid 2 has the profile with cavity hatch 16 couplings; Each placement section 22 also has the profile that is complementary with testing sample.
For obtaining better sealing effectiveness, lid 2 and variable-metric cavity 1 can be with plasticine or rubber seals, but 11 coating lubricating oil of piston 13 and cavity portion.
The method of testing of polytypic acoustical device of the present invention only need be changed different lids and the volume that changes the variable-metric cavity at the testing sample of different model, promptly selects the cavity ring of corresponding volume, just can measure the performance parameter of the acoustical device of multiple model.Not only reduce production cost, and improved resource utilization.
The above only is a better embodiment of the present invention; protection scope of the present invention is not exceeded with above-mentioned embodiment; as long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
