Description
Technical field
The present invention relates to electroacoustic field, particularly relate to a kind of Check up polarity tool and horn magnetic circuit system installation method.
Background technology
As it is shown in figure 1, horn magnetic circuit system includes Magnet 1, washer 2 and yoke 3, loudspeaker unit will be through when OQC
Cross polarity test, it is desirable to same specification, loudspeaker with batch keep consistent in same direction polarity.As in figure 2 it is shown, during test, even
Connecing wire 8 to be connected on polarity tester 7 by loudspeaker unit 6, mike 9 receives the sound of loudspeaker unit 6 and inputs polarity survey
Examination instrument 7, if polarity is consistent, green light 4 is bright, if opposite polarity, red light 5 is bright and reports to the police, in case there being the loudspeaker of opposed polarity to flow out.
In magnetic circuit system assembling process, owing to being that artificial hands takes Magnet or goes to draw Magnet 1 with iron staff, do not identify its polarity
The most consistent, therefore it is easy to anti-loaded, eventually causes the finished product loudspeaker unit polarity after assembling inconsistent, produce defective products.And
And iron staff is directly the most very stiff and demanding with Magnet contacts, has iron filings for a long time and magnetic powder remains, also can be to properties of product and outward appearance
Impact.
Summary of the invention
The technical problem to be solved is: during horn magnetic circuit system assembles, it is impossible to identify the polarity of Magnet.
In order to solve above-mentioned technical problem, the technical solution used in the present invention is: a kind of Check up polarity tool, including first
Magnet, the second Magnet and sticking plaster, described first Magnet and the second Magnet lay respectively at the two ends of described sticking plaster.
Further, described first Magnet and the second Magnet are contained in described sticking plaster, and described first Magnet and
End face indent 0.5-1mm of the second the most described sticking plaster of Magnet.
Further, described first Magnet exposed parts is S pole, and described second Magnet exposed parts is N pole.
Further, described first Magnet, the second Magnet and sticking plaster are cylinder.
A kind of horn magnetic circuit system installation method, comprises the steps:
1) required horn magnetic circuit polarity is determined；
2) go to draw Magnet with one end of Check up polarity tool；
3) Magnet is assembled by polarity.
The beneficial effects of the present invention is: a kind of Check up polarity tool of design, load onto Magnet respectively at the two ends of tool, when
When assembling horn magnetic circuit system, first determine the polarity of required horn magnetic circuit, then go to draw Magnet with Check up polarity tool one end,
Can stop anti-loaded for the polarity of Magnet from source, save follow-up loudspeaker Check up polarity program, product can be greatly improved good
Rate and production efficiency.

Detailed description of the invention
By describing the technology contents of the present invention in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate attached
Figure is explained.
The design of most critical of the present invention is: design a kind of Check up polarity tool detecting magnet polarities, is assembling loudspeaker
During magnetic circuit system, go to draw Magnet with one end of Check up polarity tool, can stop anti-loaded for the polarity of Magnet, also from source
Follow-up loudspeaker Check up polarity program can be saved.
Refer to Fig. 3, a kind of Check up polarity tool, including the first Magnet, the second Magnet and sticking plaster, described first Magnet
With the two ends that the second Magnet lays respectively at described sticking plaster.
Knowable to foregoing description, the beneficial effects of the present invention is: be provided with the first Magnet and second at the two ends of sticking plaster
Magnet, goes to draw Magnet by either end and just can detect the polarity of Magnet.
Further, described first Magnet and the second Magnet are contained in described sticking plaster, and described first Magnet and
End face indent 0.5-1mm of the second the most described sticking plaster of Magnet.
Seen from the above description, magnet surface, relative to sticking plaster sunken end face certain distance, both can ensure that between Magnet
Attract each other, the Magnet that turn avoid tool directly contacts with Magnet to be detected, can effectively prevent between Magnet mutually
Collision produces magnetic powder, effectively protection tool Magnet and detected Magnet.
Further, described first Magnet exposed parts is S pole, and described second Magnet exposed parts is N pole.
Seen from the above description, the first Magnet and the opposite polarity of the second Magnet, the different magnetic poles of Magnet can be drawn.
Further, described first Magnet, the second Magnet and sticking plaster are cylinder.
Seen from the above description, sticking plaster is designed as cylinder, makes to have during manual operation preferable feel.
A kind of horn magnetic circuit system installation method, comprises the steps:
1) required horn magnetic circuit polarity is determined；
2) go to draw Magnet with one end of Check up polarity tool；
3) Magnet is assembled by polarity.
Seen from the above description, when horn magnetic circuit system is installed, described Check up polarity tool is used can to stop from source
By anti-loaded for the polarity of Magnet, it is also possible to save follow-up loudspeaker Check up polarity program.
Refer to Fig. 3, embodiments of the invention one are: a kind of Check up polarity tool, including sticking plaster the 10, first Magnet 11
With the second Magnet 12, described first Magnet 11 and the second Magnet 12 lays respectively at the two ends of described sticking plaster 10, and three is circle
Cylindricality.Wherein, the first Magnet 11 and the second Magnet 12 relative to end face indent 0.5-1mm of sticking plaster 10, the first Magnet 11
Exposed parts is S pole, and the exposed parts of the second Magnet 12 is N pole.
The installation method of horn magnetic circuit system is described below, comprises the steps:
