Loudspeaker are compressed with the test baffle and are connected.
Further, the holder includes fixed pulley and draught line, and described draught line one end is connect with the ballast part, separately
One end is around being located on the fixed pulley.
Further, the holder further includes platform, and the platform includes perforation and the ring above the perforation
Shape part.
Further, the compressing member includes upper plate, lower plate and the connecting rod between the upper plate and lower plate, it is described on
Plate is coupled with the ballast part, and the lower end is coupled with the loudspeaker.
Further, the compressing member further includes rubber hold-down head, the rubber hold-down head be set to the lower plate lower end and
It is coupled with the loudspeaker.
Further, the ballast part is gravity code.
The beneficial effects of the utility model：
The utility model provides a kind of loudspeaker measurement jig of adjustable pressure, compared with the existing technology, has following
Advantage：
The loudspeaker measurement jig of the adjustable pressure includes test baffle, holder, compressing member and ballast part, the compression
Part is vertically arranged on the holder, and the ballast part is compressed with the compressing member activity, the ballast part weight-adjustable, test
When, the ballast part and the compressing member, which compress, to be connected, and the compressing member is compressed with the loudspeaker and connected, the loudspeaker with it is described
It tests baffle and compresses connection.The loudspeaker measurement jig of pressure is adjusted by this, we can select according to the difference of loudspeaker size
Different ballast parts is selected to carry out loudspeaker be pressed on test baffle so that loudspeaker are identical to the pressure for testing baffle, with smoothly,
It is accurately finished the test of loudspeaker acoustical behavior.
Description of the drawings
Fig. 1 is the structural schematic diagram for the loudspeaker measurement jig that pressure is adjusted in the utility model embodiment；
Specific implementation mode：
Embodiment：The preferred embodiment of the utility model is described in detail below in conjunction with the accompanying drawings, so that this practicality is new
The advantages of type and feature can be easier to be readily appreciated by one skilled in the art, to be made more to the scope of protection of the utility model
Explicit defines.
As shown in Figure 1, being a kind of loudspeaker measurement jig 100 of adjustable pressure, the acoustical behavior for loudspeaker 1 is tested.
The loudspeaker measurement jig 100 of the adjustable pressure includes test baffle 2, holder 3, compressing member 4 and ballast part 5, and compressing member 4 is lived
Dynamic to be arranged on holder 3, ballast part 5 is compressed with 4 activity of compressing member, 5 weight-adjustable of ballast part.For the ease of identifying and selecting
Ballast part 5, we generally use gravity code as ballast part 5.
In concrete structure, compressing member 4 includes upper plate 41, lower plate 42 and the connecting rod 43 for connecting upper plate 41 and lower plate 42, is
Balance, connecting rod 43 is kept to be arranged in pairs.In order to fully use mechanics principle, which is vertically arranged, in ballast part 5
When effect, 4 direct suppressing action of compressing member is in loudspeaker 1.Upper plate 41 and lower plate 42 are planar structure, and upper plate 42 and ballast part
5 matings, lower plate 42 are coupled with loudspeaker 1.In order to not destroy loudspeaker 1 during the test, as a preferred embodiment, the compressing member 4 is also
Include the rubber hold-down head 44 set on 42 lower end of lower plate, when test, rubber hold-down head 44 is in direct contact with loudspeaker 1.
Holder 3 includes fixed pulley 31 and draught line 32, and 32 one end of draught line is connect with ballast part 5, and the other end is free end,
Around being located on fixed pulley 31, for operator's hand traction.We are by being arranged fixed pulley 31 in the upper end of holder 3 and traction being arranged
Line 32, ballast part 5 can be lifted or put down by we.Holder 3 further includes platform 33, and compressing member 4 is arranged on the platform 33,
Platform 33 coordinates equipped with perforation, perforation with connecting rod 43, perforates and is additionally provided with annular element 34 over and under, the setting of annular element 34,
Increasing the frictional force between connecting rod 43 and perforation so that compressing member 4 steadily slowly pushes under 5 suppressing action of ballast part,
