Specific embodiment
Utility model is further described below in conjunction with attached drawing and specific embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of loudspeaker test fixture, including the lid 2 closed in upper and lower covers and bottom
Seat 1, the pedestal 1 are equipped with the first attachment base 401, the second attachment base 402 and limiting slot 6,401 He of the first attachment base
Second attachment base 402 is respectively arranged on the two sides of the limiting slot 6, first attachment base 401 and second link block 402
On be respectively equipped with link slot 7, first attachment base 401 is respectively corresponded in two inner sidewalls that the link slot 7 separates to be equipped with
Accommodating chamber 12 is equipped with spring 13 and steel ball 10 in each accommodating chamber 12, and one end of the spring 13 contradicts connection respectively
In the inner sidewall of the accommodating chamber 12, the other end contradicts respectively is connected to the steel ball 10, the two sides difference of the lid 2
Equipped with link block 5,5 activity of link block of 2 side of lid is riveted on second attachment base 402,2 other side of lid
