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 the two poles of the earth double-station electromagnetic switch of the present invention, including shell 1 and blocking film 2, the shell
Actuating strut 3 and bar magnet 31 are equipped in body 1, the upper end of actuating strut 3 is rotatably penetrated and arranged on the upper end cover of shell 1, and dynamic
The upper end for making bar 3 is fixedly connected with blocking film 2, and the upper surface of blocking film 2, which is equipped with, seals bed course 21, in blocking film 2 and sealing bed course 21
Equipped with corresponding opening and closing hole 22；The bar magnet 31 is secured transverse to the lower end of actuating strut 3, in the shell 1 of 3 two sides of actuating strut
Magnetic coil 4 is respectively equipped in chamber, and the two poles of the earth of the magnetic pole of two magnetic coils 4 respectively with bar magnet 31 are correspondingly arranged；Institute
It states blocking film 2 and loudspeaker contradicts, the opening and closing hole 22 in the leak holes and blocking film 2 of loudspeaker is in centered on actuating strut 3
Circular test on, the bar magnet 31 of 3 lower end of actuating strut on the other side setting is as driving and alternative pack, in two magnetism
When the energization of coil 4 generates opposite magnetic pole, bar magnet 31 is by anisotropic 3 one turn of the attracting effect of the same sex and actuating strut of repelling each other
It is dynamic, and then keep its both ends magnetic pole attracting with two magnetic coils 4 respectively, it is inverse to be passed through reverse electrical source generation magnetic pole in magnetic coil 4
When turning, bar magnet 31 rotates with it adjustment position of magnetic pole, so that blocking film 2 rotates with it switching station, opening and closing hole 22 thereon
The leak holes of face or separate loudspeaker, compact overall structure, flexible movements, energy consumption are few, can effectively improve mobile phone communication and sound
Frequency quality.
It is installed with center bearing bracket 41 in the shell 1, is equipped with central through hole 42 vertically on center bearing bracket 41, actuating strut 3 is worn
In central through hole 42, two magnetic coils 4 symmetrically are fixed on the two sides of center bearing bracket 41, and magnetic coil 4
The polar axis of polar axis and bar magnet 31 is vertically arranged；The center bearing bracket 41 is that insulating materials is prepared and by being isolated at coating
Two magnetic coils 4 are symmetrically fixed on 3 two sides of actuating strut, make the magnetic pole and item of two magnetic coils 4 by reason, center bearing bracket 41
31 both ends pole pair of shape magnet is answered, and when the magnetic pole between the energization of magnetic coil 4 and opposite end is opposite, attracts or exclude bar shaped magnetic
Iron 31 makes its rotation to realize the purpose of opening and closing 22 Switch of working position of hole.
To be arranged in series between described two magnetic coils 4, and then make two magnetic coils 4 in the magnetic pole side of same time point
To on the contrary, the polar axis of two magnetic coils 4 is parallel to each other, by series connection make that two magnetic coils 4 can be made to locate at any time
Oppositely arranged in magnetic pole, the synchronous selection of double magnetic coils 4 can make 31 quick response of bar magnet and turn to corresponding angle, letter
Change topology layout, reduces the electricity consumption energy consumption of magnetic coil 4.
Support spring 32 is equipped between 1 bottom plate of lower end and shell of the actuating strut 3, the bottom plate of shell 1, which is equipped with, to be fixed
Terminal 11, the lower end of support spring 32 are sheathed in fixing terminal 11, and the upper end of support spring 32 is contradicted with 3 lower end of actuating strut to be set
It sets, the support spring 32 for keeping the contact condition between blocking film 2 and speaker aperture face, makes to seal bed course under normal conditions
It is close to contradict in leak holes；When magnetic coil 4 is powered switching station, the magnetic of magnetic coil 4 and 31 opposite end of bar magnet
Extremely necessarily on the contrary, bar magnet 31 will drive the movement that the generation of actuating strut 3 deviates from center bearing bracket 41, compression support bullet first at this time
Spring 32 makes blocking film 2 and sealing bed course 21 be detached from loudspeaker contact surface, to make actuating strut 3 and blocking film 2, bar magnet 31 can be certainly
By 180 ° of rotation, the then power-off of magnetic coil 4 blocking film 2 under the promotion of support spring 32 continues closely to connect with loudspeaker holding
Touching, therefore support spring 32 constitutes clutch structure of the invention, can effectively improve whole sensitivity, reduces magnetic coil 4
Energy consumption.
The above description is only a preferred embodiment of the present invention, thus it is all according to the configuration described in the scope of the patent application of the present invention,
The equivalent change or modification that feature and principle are done, is included in the scope of the patent application of the present invention.
