With it is described test baffle compress connect.
Further, the support includes fixed pulley and draught line, and described draught line one end is connected with the ballast part, separately
One end is around being located on the fixed pulley.
Further, the support also 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 also includes rubber hold-down head, the rubber hold-down head located at the lower plate lower end and
It is coupled with the loudspeaker.
Further, the ballast part is gravity code.
Beneficial effects of the present invention：
The invention provides a kind of loudspeaker measurement jig of adjustable pressure, relative to prior art, has advantages below：
The loudspeaker measurement jig of the adjustable pressure includes test baffle, support, compressing member and ballast part, the compression
Part is vertically arranged on the support, and the ballast part compresses with 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
Test baffle and compress connection.The loudspeaker measurement jig of pressure is can adjust 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.
Brief description of the drawings
Fig. 1 is the structural representation for the loudspeaker measurement jig that pressure is can adjust in the embodiment of the present invention；
Embodiment：
Embodiment：Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages of the present invention
It can be easier to be readily appreciated by one skilled in the art with feature, so as to make protection scope of the present invention on apparent clear and definite boundary
It is fixed.
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, support 3, compressing member 4 and ballast part 5, compressing member 4 and lived
Dynamic to be arranged on support 3, ballast part 5 compresses with the activity of compressing member 4, the weight-adjustable of ballast part 5.For the ease of identifying and selecting
Ballast part 5, we are typically using gravity code as ballast part 5.
In concrete structure, compressing member 4 includes upper plate 41, lower plate 42 and connection upper plate 41 and the connecting rod 43 of lower plate 42, is
Balance is kept, connecting rod 43 is arranged in pairs.In order to fully use mechanics principle, the compressing member 4 is vertically arranged, with ballast part 5
During 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 in test process, as a preferred embodiment, the compressing member 4 is also
Including the rubber hold-down head 44 located at the lower end of lower plate 42, during test, rubber hold-down head 44 directly contacts with loudspeaker 1.
Support 3 includes fixed pulley 31 and draught line 32, and the one end of draught line 32 is connected 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 setting fixed pulley 31 in the upper end of support 3 and setting traction
Line 32, ballast part 5 can be lifted or put down by we.Support 3 also includes platform 33, and compressing member 4 is arranged on the platform 33,
Platform 33 is provided with perforation, and perforation coordinates 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 the suppressing action of ballast part 5,
Avoid pushing and too urgent loudspeaker 1 are caused to damage.
During test, first loudspeaker are placed on test baffle 2, we select the ballast of appropriate weight according to loudspeaker size
