Vibration-sand-based horn text fixture

Abstract

The invention discloses a vibration-sand-based horn text fixture comprising a left substrate, a right substrate, side panels, a horn base, triangular clamp slots, key slots, connecting screws, assembling screw holes, fixed screw holes, and changing stand screw holes. The key slots are formed in the left substrate and the right substrate; and the side panels arranged symmetrically are clamped in the key slots. The side panels and the left substrate and the right substrate are fixed by the connecting screws. The horn base is arranged at the tops of the side panels; a horn position hole and the triangular clamp slots are formed in the horn base; and the assembling screw holes are formed in the periphery of the horn position hole. A plurality of wire holes are formed in the middle of the side panels. A plurality of changing stand screw holes are formed in the left substrate and the right substrate in a circular mode and are fixedly connected with a changing stand of an electrical mechanical vibration machine. The text fixture is made of a high-strength aviation aluminum alloy material; the left substrate and the right substrate are assembled to the changing stand in reciprocating rotation; and vibration performance testing is carried out on the horn by the electrical mechanical vibration machine and the vibration testing effect is good.

Description

technical field [0001] The invention relates to the field of horn testing technical equipment, in particular to a vibrating table horn testing jig. Background technique [0002] With the development of the automobile industry, the production level and technical requirements of automotive speakers are constantly improving, and the industry requires more testing of automotive speakers in order to meet the quality requirements of manufacturers for speaker products. [0003] In the prior art, the mechanical vibration test of the horn is done through a vibrating table. The shortcomings and deficiencies in the prior art are: the vibration test effect is not good, and the high-frequency vibration requires high fixation and stability of the horn, and the jig for assembling the horn Stability, material strength, and long-term vibration cause the deformation of the test piece itself. Because the mechanical vibration test of the horn needs to fix the horn on the vibration table in a ce...

[0003] In the prior art, the mechanical vibration test of the horn is done through a vibrating table. The shortcomings and deficiencies in the prior art are: the vibration test effect is not good, and the high-frequency vibration requires high fixation and stability of the horn, and the jig for assembling the horn Stability, material strength, and long-term vibration cause the deformation of the test piece itself. Because the mechanical vibration test of the horn needs to fix the horn on the vibration table in a certain direction, there is no vibration test on the rotation change during the test, resulting in vibration detection and actual The vibration does not match, resulting in poor test results
