Detailed Description

In order to explain the technical content, the objects and the effects of the present invention in detail, the following description is made with reference to the accompanying drawings in combination with the embodiments.

Referring to fig. 1 to 3, a speaker testing fixture includes a base 1, a vertical guide rail 2, a slider 3, a placing table 4 and two buckling detection blocks 5, wherein the vertical guide rail 2 is disposed on the base 1, the slider 3 is slidably disposed on the vertical guide rail 2, the placing table 4 is connected to the slider 3, and the two buckling detection blocks 5 are disposed on the base 1 at intervals to form a slot 6.

The utility model discloses a structural principle brief follows as follows: a clamping groove 6 is formed in the position, needing to be checked, of the checking fixture corresponding to the loudspeaker product 20, when the placing table 4 slides up and down, if the size of the position, needing to be checked, of the loudspeaker product 20 is not beyond the specification, the loudspeaker product 20 can be smoothly installed in the checking fixture; otherwise, if the dimension exceeds the upper limit specification, the speaker product 20 will be tilted because it cannot be installed in the testing tool.

From the above description, the beneficial effects of the present invention are: the user only needs to place the speaker product 20 on the placing table 4 and then slide the placing table 4 to check whether the clipping position of the speaker product 20 exceeds the size standard, and the detection efficiency is extremely high.

Furthermore, a positioning structure is arranged on the placing table 4.

Further, the number of the positioning structures is multiple.

Further, the positioning structure is a positioning column 9.

As is apparent from the above description, the positioning structure on the placement table 4 cooperates with the cooperating positioning structure on the speaker product 20, thereby achieving the positioning of the speaker product 20 on the placement table 4.

Further, a magnet 10 is provided on the placement stage 4.

As can be seen from the above description, the magnet 10 can be magnetically engaged with the magnetic circuit component in the speaker product 20, so that the speaker product 20 can be attached to the placing table 4.
