Problems solved by technology

However, since the elastic band will cause the elastic force to weaken and disappear after long-term use, its fixing power will gradually weaken
Moreover, it is difficult to perform fixed tests on loudspeakers of different thicknesses in the traditional way, which will easily lead to the test being affected, thereby affecting the accuracy of the test results

Abstract

The invention relates to a loudspeaker testing device, which comprises a baffle and a base, and the baffle is arranged on the base. The loudspeaker testing device also includes a receiving plate, a bead, a fixing piece and a positioning piece. The receiving plate includes a body and an edge, and the middle part of the body A positioning slot is provided, a through hole is provided in the middle of the positioning slot, a test hole is provided on the baffle plate, and an installation slot is provided around the test hole, the body is accommodated in the test hole, and the edge is accommodated in the installation slot, The bead is arranged on the baffle, the fixing member can be adjusted to pass through the middle of the bead, and the positioning member is arranged at one end of the bead. The loudspeaker testing device of the present invention can meet the test and fixation of loudspeakers of different sizes, and the positioning of the loudspeaker is convenient and fast, which effectively improves the testing efficiency; in addition, the long-term testing will not lead to weakening of the loudspeaker fixing force, avoiding the instability of the testing device and affecting the loudspeaker test result.

Description

technical field [0001] The invention relates to the technical field of loudspeakers, in particular to a loudspeaker testing device. Background technique [0002] Today, loudspeakers can often be tested with a baffle to detect the frequency and distortion of the loudspeaker. The loudspeaker needs to be fixed on the baffle during testing, and the traditional fixing device uses elastic bands to fix the loudspeaker in the accommodation cavity of the baffle. However, since the elastic band will cause the elastic force to weaken and disappear after long-term use, its fixing power will gradually weaken. Moreover, it is difficult to perform fixed tests on loudspeakers of different thicknesses in the traditional way, which easily leads to the test being affected, thereby affecting the accuracy of the test results. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned technical problems and provide a loudspeaker testing device. [...
