Specific embodiment
Technical solution of the present invention is illustrated with embodiment with reference to the accompanying drawing.
As shown in Figure 1, a kind of rotary double-station electromagnetic switch of the present invention, including hollow shell 1 and disc type
Blocking film 2, be transversely provided with actuating strut 3 in the shell 1, offer movement hole 11 on the front bulkhead of shell 1, before actuating strut 3
End is fixedly connected across movement hole 11 and with the blocking film of front side 2, and bar magnet 31 is longitudinally equipped on actuating strut 3;The movement
The two sides of bar 3 are equipped with magnetic coil 4, and polar axis and the actuating strut 3 of magnetic coil 4 are arranged in parallel;The blocking film 2 is equipped with opening and closing
Hole 21, the front end face of blocking film 2 are equipped with sealing bed course 22, and sealing bed course 22 drops the tooth socket 23 that rubs equipped with several;The blocking film 2 with
Loudspeaker contradicts setting, and the opening and closing hole 22 in leak holes and blocking film 2 on loudspeaker is on same Circular test, bar magnet
31 driving part as actuating strut 3, when two magnetic coils 4 are powered and when pole orientation is opposite, bar magnet 31 by
The opposite sex is repelled each other the attracting effect of the same sex and 3 unitary rotation of actuating strut, so make its both ends magnetic pole respectively with two 4 phases of magnetic coil
It inhales, when two magnetic coils 4 are passed through reverse electrical source and generate magnetic pole reverse, bar magnet 31 rotates with it adjustment position of magnetic pole,
To which blocking film 2 rotates with it switching station, opening and closing 22 face of hole thereon or the leak holes far from loudspeaker, sealing bed course 22 are used
In raising blocking film 2 to the sealing effect of leak holes, several friction systems dropping the tooth socket 23 that rubs and can reducing between ground blocking film 2 and loudspeaker
Number, to improve the sensitivity of actuating strut 3, compact overall structure, flexible movements, energy consumption are few, can effectively improve mobile phone communication and
Audio quality.
The blocking film 2 is equipped with several opening and closing holes 21, and any opening and closing hole 21 is only connected to unique tooth socket 23 that rubs that drops, and if
Dry opening and closing hole 21 is opened in respectively on the concentric circles of the different-diameter centered on actuating strut 3;Several opening and closings in the blocking film 2
Hole 21 can control multiple loudspeakers respectively, to improve call and audio quality.
Center bearing bracket 41 is equipped in the shell 1, center bearing bracket 41 is equipped with the pilot hole 42 concentric with movement hole 11, moves
The rear end for making bar 3 is arranged in pilot hole 42;Described two magnetic coils 4 are symmetricly set on the two sides cavity of center bearing bracket 41
It is interior;The center bearing bracket 41 is for assembling actuating strut 3 and magnetic coil 4, so that two magnetic coils 4 be made symmetrically to be fixed on
The two sides of actuating strut 3, actuating strut 3 can generate suction to bar magnet 31 when magnetic coil 4 is powered along 42 fore-aft travel of pilot hole
Gravitation, so that blocking film 2 be made to be detached from loudspeaker to reduce coefficient of friction when rotation.
The front of the shell 1 is equipped with partition 12, and center bearing bracket 41 is fixed between partition 12 and 1 end plate of shell, every
