Embodiment 1

[0022] A fixture for loudspeaker vibration testing, including a bottom plate 1, an end plate 5 and a support column 11, the right end of the bottom plate 1 is provided with a reserved groove, the middle part of the reserved groove is provided with a positioning cover 2, and the positioning cover 2 is a semicircular cylinder Shell, the right end of the positioning cover 2 is transitionally connected with the extension cover 3, the middle part of the extension cover 3 is provided with a strip-shaped chute 4, and the left end of the chute 4 runs through to the middle of the bottom surface of the positioning cover 2, and the end plate 5 is fixed on the bottom plate 1 The lower surface of the left end of the end plate 5 and the right side of the end plate 5 are fixed with two horizontal sliding rods 6, the sliding rods 6 pass through the shaft holes corresponding to the lower end of the slider 601, the upper end of the slider 601 is fixed with a positioning seat 7, and the positionin...

Embodiment 2

[0025] The difference between this embodiment and Embodiment 1 is:

[0026] In this embodiment, the positioning seat 7 includes a side block 701 and a support plate 702, the support ring 702 is fixed on the upper surface of the slider 601, the right side of the upper surface of the support plate 702 is transitionally connected with the side block 701, and the support plate 702 is a semicircle shaped plate, and the diameter of the support plate 702 is equal to the diameter of the positioning cover 2, the connector 9 includes a nut 901 and a rotating seat 902, the nut 901 is threaded with the upper end of the guide rod 13, and the upper end of the nut 901 is rotatably connected with a rotating seat 902 , and the rotating seat 902 is hinged with the lower end of the handle 16 .

[0027] Specifically, the positioning seat 7 can move horizontally, cooperate with the positioning cover 2 to stabilize the clamping of the horn, and the connecting piece 9 realizes the rotational connect...

Embodiment 3

[0029] The difference between this embodiment and Embodiment 1 is:

[0030] In this embodiment, it also includes a connecting plate 17 and a slanting plate 18. The two ends of the connecting plate 17 are fixedly connected to the front and rear sides of the reserved groove of the bottom plate 1 respectively. Low right high, also includes cross bar 19 and push plate 20, one end of cross bar 19 is fixed on the outer surface of side block 701, and the other end of cross bar 19 is fixed with push plate 20.

[0031] Specifically, the limiting plate 8 cooperates with the supporting plate 702 to limit the horn during the transfer process, and when clamping and closing, the slant plate 18 and the extension cover 3 are used to limit the position, which can ensure the accuracy of the position.

[0032] When in use: first place the horn to be tested on the support plate 702 of the positioning seat, the lower end of the horn is in the "凵" type limit plate 8, and the left hand pulls the han...

Abstract

The invention discloses a clamp for a horn vibration test. The clamp comprises a bottom plate, end plates and supporting columns, a reserved groove is formed in the right end of the bottom plate; a positioning cover which is a semicircular barrel shell is arranged in the middle of the preformed groove; the right end of the positioning cover is in transition connection with an extending cover; a strip-shaped sliding groove is formed in the middle of the extending cover. The left end of the sliding groove penetrates to the middle of the bottom face of the positioning cover. The end plate is fixed to the lower surface of the left end of the bottom plate. Two sliding rods in the horizontal direction are fixed to the right side face of the end plate. Each sliding rod penetrates through a shafthole corresponding to the lower end of the sliding block; a positioning seat is fixed to the upper end of the sliding block, a limiting plate is fixed to the lower surface of the positioning seat, a mounting plate is fixed to the right end of the sliding rod, and the lower end of the supporting column is fixedly connected with the left end of the upper surface of the bottom plate. The clamp for horn vibration test is simple in structure, rapid in clamping, capable of guaranteeing horn stability and reducing detection errors and good in using effect.

Description

technical field [0001] The invention relates to the technical field of horn processing, in particular to a fixture for horn vibration testing. Background technique [0002] The loudspeaker is a transducer device that converts electrical signals into acoustic signals, and the performance of the loudspeaker 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. Audio electric energy makes its paper cone or diaphragm vibrate and resonate (resonate) with the surrounding air through electromagnetic, piezoelectric or electrostatic effects to produce sound. The loudspeaker needs to be tested in an all-round way before leaving the factory. The loudspeaker is prone to vibration during the testing process, thereby affecting the testing effect. The existing fixture has a simple structure and a poor fixing effect. Co...
