Test fixture and audition test equipment

Abstract

The embodiment of the invention discloses a test fixture and listening test equipment, the test fixture is used for listening test of a loudspeaker monomer, the loudspeaker monomer is provided with a first sound production surface and a second sound production surface which are oppositely arranged, the test fixture comprises a base and a cover plate, and the cover plate is oppositely arranged with the base and can move relative to the base. When the cover plate moves to a first station relative to the base, a cavity capable of accommodating the loudspeaker monomer is formed between the cover plate and the base; the first sound outlet is formed in the lower end of the base, the second sound outlet is formed in the upper end of the cover plate, the first sound outlet corresponds to the first sound production surface, and the second sound outlet corresponds to the second sound production surface. Therefore, during testing, after the loudspeaker monomer is installed in the testing jig, the actual installation effect can be better restored, so that the accuracy of the listening test result of the double-sided sounding loudspeaker monomer can be ensured, and meanwhile, the testing efficiency can also be improved.

Description

technical field [0001] The invention relates to the technical field of loudspeaker testing, in particular to a testing fixture and listening testing equipment. Background technique [0002] Before the speaker unit is installed in the electronic equipment, a listening test is required to ensure the quality of the speaker unit. In order to improve the efficiency of the listening test, a test fixture is used to install the speaker unit to be tested in the related art. The double-sided sounding speaker unit can achieve the effect of two-way sounding by setting two sets of vibration components. Traditional listening test fixtures are mostly designed for single-sided speakers, and double-sided speakers cannot be tested with traditional listening test fixtures; even if they can be used, the degree of adaptation is low. However, it is impossible to accurately restore the sound field after the actual installation of the double-sided sounding speaker, which may easily lead to misjud...

Problems solved by technology

Traditional listening test fixtures are mostly designed for single-sided sounding speaker units, and double-sided sounding speaker units cannot be tested with traditional listening test fixtures; even if they can be used, the degree of adaptation is low. It is impossible to accurately restore the sound field after the actual installation of the double-sided sounding speaker unit, which may easily lead to misjudgment and affect the accuracy of the test results.
