Between interval corresponding to central angle be 40 ° to 10 ° between.
The distance for the length that the length of the single fan plate is less than the single Air Filter accounts for the length of the single fan plate
10% to 20% between.
The edge of the single fan plate is equipped with the fillet for the user that avoids colliding with, and the fillet is along the single fan plate
Edge extending direction extend.
The utility model has the beneficial effects that:
1. the utility model blocks the Air Filter by the way that the dustproof cover is arranged above the Air Filter, from
And avoid dirt accumulation in the dust-proof net surface；
2. the dustproof cover and the fixing seat are rotatablely connected, to facilitate the normal use of earpiece, be conducive to user
Air Filter is quickly blocked or exposed by dustproof cover；
3. being used in combination by fan-shaped fan-shaped dustproof cover and fan-shaped Air Filter, it can effectively be conducive to the space on mobile phone,
So that the earphone structure of mobile phone is more compact, the volume of mobile phone is reduced.
4. can effectively ensure that the normal use of earpiece, i.e., by using the fan-shaped dustproof cover that short fan-shaped Air Filter one is cut
It blocks fan-shaped dustproof cover accidentally not being able to rotate, it is also ensured that the normal use of earpiece, the phenomenon that not will lead to microphonia
Occur.
Detailed description of the invention
Fig. 1 is the top view of the utility model；
