Bolt.
Preferably, first spiral cover and the first speaker net are identical specification, and on the first spiral cover and the first speaker net
Lower alignment.
Preferably, the height that the height of first spiral cover is greater than the first spiral cover inner bolt adds the height of sliding shoe.
Preferably, the sliding groove is ring structure, and the diameter of sliding groove is less than the first spiral cover to the first speaker net
Linear distance.
Preferably, first speaker net and the second speaker net are same size, and the first speaker net and another first loudspeaker
The fan-shaped white space formed between net is equal to the size of the first speaker net.
Preferably, the length of the bolt is greater than the thickness of sound chamber upper end.
Compared with prior art, the utility model has the beneficial effects that this facilitates the speaker net dust cover of folding, existing
Speaker net on the basis of, carried out addition the first spiral cover, sliding groove, the first speaker net, the second spiral cover, sliding shoe, the second loudspeaker
The change of net can be used by the first spiral cover of setting, the first speaker net, the second spiral cover and the second speaker net in loudspeaker
When open speaker net, do not influence loudspeaker uses audio, by being used cooperatively for sliding shoe and sliding groove, rotates the first spiral cover
Dust is blocked so that the first speaker net and the second speaker net be made to interlock up and down with the second spiral cover, and that reduces that dust enters sound chamber can
Can, improve the service life of speaker net.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution: a kind of speaker net dust cover facilitating folding, packet
It includes the first spiral cover 1, sliding groove 2, counterbore 3, the first speaker net 4, sliding shoe 5, the second spiral cover 6, the second speaker net 7, sound chamber 8, wear
Hole 9 and bolt 10 offer sliding groove 2 in first spiral cover 1, symmetrically arranged counterbore 3, the first spiral cover 1 are offered on sliding groove 2
It is inside fixedly connected with the first speaker net 4 around setting, sliding shoe 5 is slidably connected in sliding groove 2, the upper end of sliding shoe 5 is solid
Surely it is connected with the second spiral cover 6, the second speaker net 7 around setting, the lower end of the first spiral cover 1 are fixedly connected in the second spiral cover 6
It is fixedly connected with sound chamber 8,8 upper end of sound chamber offers perforation 9, is provided with bolt 10 between perforation 9 and counterbore 3；
Further, the first spiral cover 1 and the first speaker net 4 are identical specification, and the first spiral cover 1 and the first speaker net 4
Consistency from top to bottom, by being used cooperatively for the first spiral cover 1 and the first speaker net 4, convenient for adjusting the folding of speaker net.
Further, the height that the height of the first spiral cover 1 is greater than 1 inner bolt 10 of the first spiral cover adds the height of sliding shoe 5,
Ensure that bolt 10 is lower than sliding shoe 5, and does not influence the normal rotation of sliding shoe 5.
Further, sliding groove 2 is ring structure, and the diameter of sliding groove 2 is less than first the 1 to the first speaker net of spiral cover 4
Linear distance, by be arranged sliding groove 2, convenient for the sliding of sliding shoe 5, so as to adjust the first speaker net 4 and the second speaker net 7
Between distance, block dust or play the better audio of loudspeaker.
Further, the first speaker net 4 and the second speaker net 7 are same size, and the first speaker net 4 and another first loudspeaker
The fan-shaped white space formed between net 4 is equal to the size of the first speaker net 4, it is ensured that in the first speaker net 4 and the second speaker net 7
When down staggeredly, dust can be sheltered from completely, dust is avoided to enter in speaker net；
Further, the length of bolt 10 is greater than the thickness of 8 upper end of sound chamber, by the way that bolt 10 is arranged, enhances sound chamber 8 and the
Stability between one spiral cover 1.
Working principle: it is by counterbore 3 and bolt 10 that first spiral cover 1 and sound chamber 8 is fixed first, when needing loudspeaker to play sound
When frequency, the second spiral cover 6 is rotated, the sliding shoe 5 of 6 lower end of the second spiral cover slides in the sliding groove 2 in the first spiral cover 1 at this time, directly
It is completely coincident to the first speaker net 4 and the second speaker net 7, starts to play audio file, audio is from sound chamber 8 toward 1 end of the first spiral cover
It diverges and, lacked the obstruction of speaker net, result of broadcast is more preferable, after use, when needing to block dust, rotates the again
Two spiral covers 6, sliding shoe 5 slide in sliding groove 2 again, until the second speaker net 7 fills up the first speaker net 4 and another first loudspeaker
Blank parts between net 4 complete the opening and closing movement of speaker net.
Finally it should be noted that the above content is only to illustrate the technical solution of the utility model, rather than it is practical to this
The limitation of novel protected range, those skilled in the art to the technical solution of the utility model carry out it is simple modification or
Person's equivalent replacement, all without departing from the spirit and scope of technical solutions of the utility model.
