Embodiment 1

[0018] Embodiment 1: A multifunctional test platform for a speaker, comprising a table board 1, four legs 24 are distributed on the lower surface of the table board 1, and a fixing plate 9 is connected to the left side of the upper surface of the table board 1 through a reinforcement board 12, The structural strength is increased by the reinforcement plate 12, and the fixed plate 9 is vertically arranged with the table top 1, and a retaining ring 30 is arranged in the hole in the middle of the left surface of the fixed plate 9, and the left surface of the retaining ring 30 is connected with a movable ring 10 by a mounting stud. , the middle part of the movable ring 10 is provided with a speaker 11. When the model of the speaker 11 is relatively large, the movable ring 10 is disassembled, and the speaker 11 is directly connected to the retaining ring 30, which is convenient for adapting and installing various types of speakers. The left side of the surface is provided with an au...

Embodiment 2

[0023] The difference between this embodiment and embodiment 1 is:

[0024] In this embodiment, the front surface of the table board 1 is provided with a U-shaped block 18, and a second fastening stud 17 is threaded in the screw hole on the lower surface of the U-shaped block 18, and the end of the second fastening stud 17 is connected to the Table 1 contacts, and the upper surface of U-shaped block 18 is provided with gooseneck 19, and the upper end of gooseneck 19 is connected with microphone 21 through placement block 20, and the output end of microphone 21 is electrically connected with the input end of power amplifier module 13.

[0025] Specifically, the microphone 21 can be used to speak to the power amplifier module 13, adding a test method, and when the gooseneck 19 is twisted, the microphone 21 can be driven to move.

Embodiment 3

[0027] The difference between this embodiment and embodiment 1 is:

[0028] In this embodiment, the sliding structure 29 includes a sliding bar 25, the sliding bar 25 is arranged on the upper surface of the connecting bar 28, the upper surface of the sliding bar 25 is slidably connected with the second slider 26, and the telescopic mechanism 27 includes a sleeve 8, the sleeve 8 is arranged on the upper surface of the second slide block 26, and the middle part of the casing 8 is provided with a movable column 7, and a third fastening stud 22 is threaded in the screw hole on the side surface of the casing 8, and the third fastening stud 22 The end of the contact with the side surface of the movable column 7.

[0029] Specifically, the second slider 26 can slide on the slide bar 25, and the position of the test can be changed. The movable column 7 can move in the sleeve pipe 8, which is convenient for adjusting the height of the wave recorder 6, and can test the sound of differen...

Abstract

The invention discloses a multifunctional test platform of a loudspeaker. The multifunctional test platform comprises a table plate, four supporting legs are distributed on the lower surface of the table plate in an array mode. The left side of the upper surface of the table plate is connected with a fixing plate through a reinforcing plate; a baffle ring is arranged in a hole in the middle of theleft surface of the fixing plate; the left surface of the baffle ring is connected with a movable ring through a mounting stud; the loudspeaker is arranged in the middle of the movable ring, an audioanalyzer is arranged on the left side of the upper surface of the table plate; a power amplifier module is arranged on the upper surface of the audio analyzer; a positioning plate is arranged on theright side of the upper surface of the table plate; a positioning rod is arranged on the positioning plate; the multifunctional test platform of the loudspeaker is diverse in test function, when the types of the loudspeakers are large, the movable ring is detached, the loudspeakers are directly connected with the baffle ring, the loudspeakers of various types can be adapted and installed, the testeffect is good, the sound effects of different distances can be detected, data can be automatically recorded, and whether the loudspeakers are qualified or unqualified can be judged.

Description

technical field [0001] The invention relates to the technical field of horn testing, in particular to a multifunctional testing platform for horns. Background technique [0002] A horn, also called a speaker, is a transducer device that converts an electrical signal into an acoustic signal. The performance of the speaker has a great influence on the sound quality. The loudspeaker is the weakest part in the audio equipment, but it is the most important part for the sound effect. There are many types of speakers, and their prices vary widely. Speakers need to be tested for multiple items before leaving the factory. In the prior art, the speaker testing equipment has fewer functions, fewer test items, and cannot be adapted to various types of speakers. The test effect is not good, and it cannot detect sound effects at different distances, and cannot automatically record data and judge Speaker pass and fail. Contents of the invention [0003] The technical problem to be so...
