Lug boss stirs middle level mechanism, it is slided or is rotated between interior loop mechanism and outer ring structure.
The media layer damage subcylindrical, about 200-300 ° of its circumference are sheet metal entity, and 60-160 ° is hollow-out parts
Point, the openwork part can be lattice-shaped either poroid sheet metal or the 60-160 ° of openwork part for basic missing or
Person lacks completely.When outer ring structure carries out circle rotation in inner ring structure outer surface, when outer ring structure and inner ring structure
When openwork part essentially coincides, entity part essentially coincides, external voice input can be now received, it is defeated according to the sound of user
Enter direction, stir media layer damage, make openwork part against user's input position.
There is the above to understand that media layer damage of the invention can effectively stop the noise in other directions.
Meanwhile outer ring structure can be rotated when microphone need not be used so that sound can not input, and be made an uproar so as to stop
Sound.
Selected as one kind, the outer surface of the inner ring structure sets raised block, and the block can stop that outer ring is tied
Structure, it is easy to be defined the rotation direction of outer ring structure.Block can be for 2 and more than 2 it is multiple.In certain design,
When (or counterclockwise) rotates to certain position and stopped by block outer ring structure clockwise, now outer ring structure and inner ring structure are engraved
Empty part essentially coincides, entity part essentially coincides, and when outer ring structure, (or clockwise) rotates to certain position by block counterclockwise
During stop, the entity part of outer ring structure blocks the openwork part of inner ring structure completely.
By way of above-mentioned block, it is easy to user to be easy to, sensitive finds rotation position.
Embodiment five
The present embodiment is carried out on the basis of previous embodiment 1 or 2 or 3 or 4, or above-described embodiment any combination
, mainly introduce a kind of wireless communications method of the audio adaptation apparatus using above-mentioned radio station.
The wireless communications method of a kind of audio adaptation apparatus using above-mentioned radio station, by the audio of aforementioned radio platform
Adaptive device is used for the successive radio communication of wireless locomotive.The wireless locomotive is multiple, is followed successively by a car, the second car, the 3rd
Car ... car third from the bottom, car second from the bottom, trailer.Communication is used between each locomotive.
Audio adaptation apparatus is set on head car.Head car sends director data and is transmitted to the 3rd car to the second car, the second car, according to
It is secondary to be transferred to trailer.When trailer sends reply data, data itself is sent to car second from the bottom by trailer, and car second from the bottom will
Trailer data and this car data are sent to car third from the bottom, car third from the bottom by trailer data, car data second from the bottom and itself
Data are sent to fourth from the last car, in this way all data transfers to head car.
In order to obtain the status data of each locomotive (or other desired data), the gathered data by the way of inspection, tool
The acquisition mode of body is：
1st, polling period is set as t；The setting up procedure is set by control centre, or is set by head car.
2nd, when inspection starts, from the beginning car starts for time starting, and from the beginning car sends time of instruction and is designated as " zero moment ", anticipates
Taste inspection and started.
3rd, each locomotive record receives the time ts of instruction or data, and also record sends the time tf of instruction or data.Often
The processing time of one locomotive is tc=tf-ts.
4th, the time-consuming tt of each inspection is calculated.When n locomotive be present, inspection, which takes, is：
5th, inspection is calculated to terminate to time tx, the tx=t-tt of inspection next time, i.e. inspection to open after terminating the rear tx times
Open second of inspection.
6th, inspection time lag rate v is calculated.Using such as preceding step 1-5 method, inspection Startup time should be 0, t in theory,
2t, 3t, 4t ..., it is tq at the time of actual0、tq1、tq2、tq3、tq4…
Then first time inspection time lag rateSecond of inspection time lag rateIt is tired
Count inspection time lag
