During, probe contacts are hampered power to after dynamic iron core measurement point instantly, and upper probe overcomes the elastic force of shell fragment to move downward, is
Iron core measurement point provides an active force so that dynamic iron core bottom surface and static iron core are contacted in loudspeaker.
The standing part of described displacement transducer is coupled with column, and slipper is coupled with guide pillar, and guide pillar couples simultaneously
Upper probe and lower probe, by the amount of movement between probe on displacement sensor and lower probe.
Described operation handle makes guide pillar move up and down by rack-and-pinion, thus driving the sliding part of displacement transducer
Point, upper probe and lower probe movement, so that gear is rotated on tooth bar by depression handle, realize the motion of guide pillar, guide pillar
Motion drives slipper, upper probe and the lower probe movement of displacement transducer.
The external electrical of described display is connected with display lamp, public up and down by display interior program setting gap
Whether qualified difference, drive display lamp light to show.
Described loudspeaker fixing mould, guide pillar, upper probe and the assembling of lower probe coaxial line are it is ensured that the effect of measurement.
This utility model compared with prior art, has the advantages that：
A kind of loudspeaker magnetic gap measuring apparatus are provided, can effectively measure the magnetic gap of loudspeaker, be conducive to properties of product
Concordance, improves the quality of product, product process detection data not only improves the data analysiss of product, is conducive to product
The concordance of performance, makes the key characteristic " tone " of electric horn, that is, " fundamental frequency " of GB15742 Standard is effectively controlled
System, meets high-grade car " tone " concordance design requirement, can be widely applied to loudspeaker and produces in detection.

Specific embodiment
With reference to the accompanying drawings and examples this utility model is further described：
Embodiment
As shown in Figure 1-2, loudspeaker magnetic gap measuring apparatus described in the utility model, including base 1, the top of base 1
It is provided with loudspeaker fixing mould 2 and column 3, column 3 is provided with guide pillar 8, the outside connection of guide pillar 8 has operation handle 7, by operation
Handle 7 can make guide pillar 8 move up and down on column 3, and the outside of guide pillar 8 also couples displacement transducer 9, the lower section of guide pillar 8
Be provided with probe 6 and lower probe 4, the lower probe 4 of upper probe 6 connection, displacement transducer 9 be used for measuring probe 6 and lower probe 4 it
Between distance, displacement transducer 9, upper probe 6 and lower probe 4 electrical connection display 10.
