The utility model is used for the oral english teaching is with adjustable ear muff.
Description
The technical field is as follows:
the utility model relates to an english oral language teaching is with headset, concretely relates to english oral language teaching is with adjustable ear muff.
Background art:
at present english teaching in-process all is that the teacher communicates with the student through the headset, and the ear muff on the current headset seat is fixed, because teacher and student's ear size, shape all are inconsistent, consequently can cause some teacher and student's ear to have half to be pushed down by the ear muff and carry out the training of spoken language and hearing, can cause uncomfortable of ear like this for a long time.
The utility model has the following contents:
the utility model aims at solving the problem that the earmuffs on the existing headset seat are fixed, and providing an adjustable earmuff for oral english language teaching, which can be adjusted by the size of the earmuffs.
The above purpose is realized by the following technical scheme:
the utility model provides an oral english teaching is with adjustable ear muff, its constitution includes: the headset seat, headset seat inside from interior to outer concentric arrangement have rubber circle, interior crown plate and ring piece, interior crown plate on be provided with four branch, the one end of branch be fixed with the circular arc piece, the circular arc piece with the outer wall fixed connection of rubber circle, the other end and the stationary blade of branch articulated, the stationary blade fix the outer wall of interior crown plate on and with the outer wall of interior crown plate pass through spring coupling, interior crown plate inner wall be fixed with four slopes, the slope with the stationary blade tip contact.
The oral english teaching of using adjustable ear muff, the ring piece outer wall be fixed with the plectrum, the plectrum be located the recess of headset seat in.
Has the advantages that:
1. the utility model discloses a stir the plectrum and realize the change at slope and fixed plate contact position to realize the position change of branch, through the elastic deformation effect of rubber circle, realize the size change of ear muff, make its mr and the student that is applicable to different ear sizes and shapes.
2. The utility model discloses simple structure does not have any circuit connection form, can not produce any influence to the circuit in the headset seat.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
in the figure: 1. a limiting plate; 2. a headset base; 3. an inner ring plate; 4. a ring piece; 5. arc sheets; 6. a spring; 7. a fixing sheet; 8. a strut; 9. a shifting sheet; 10. a rubber ring; 11. a groove; 12. a ramp.
The specific implementation mode is as follows:
example 1:
the utility model provides an oral english teaching is with adjustable ear muff, its constitution includes: the earphone seat 2 is internally provided with an audio output circuit, the earmuff is a whole consisting of other components except the earphone seat, the inside of the earphone seat is concentrically provided with a rubber ring 10, an inner ring plate 3 and a ring piece 4 from inside to outside, the rubber ring is used for contacting with the periphery of an ear to prevent discomfort for a long time, the inner ring plate is adhered on the earphone seat, the ring piece can rotate inside the earphone seat, the inside of the earphone seat is provided with a ring groove, the outside of the earphone seat is fixed with a ring limiting plate 1, the bottom surface of the limiting plate is also provided with a ring groove, the upper side of the ring piece is positioned in the ring groove of the limiting plate, the lower side of the ring piece is positioned in the ring groove of the earphone seat to ensure that the ring piece can rotate and can be limited in position, the inner ring plate is provided with four supporting rods 8, and the supporting rods pass through the inner ring plate and can slide in the inner ring plate, the one end of branch be fixed with circular arc piece 5, branch and circular arc piece, headset seat and interior crown plate, circular arc piece and rubber circle all are the form that bonds, the circular arc piece with the outer wall fixed connection of rubber circle, the other end of branch articulated with stationary blade 7, the stationary blade fix the outer wall of interior crown plate on and with the outer wall of interior crown plate pass through spring 6 and connect, the stationary blade is rotatable plastic sheet, fix and to rotate on the outer wall of interior crown plate, interior crown plate inner wall be fixed with four slopes 12, the inclination on slope is 35-45 degrees, the slope with stationary blade tip contact, the stationary blade tip is convex, blocks when preventing to contact and ends.
Example 2:
according to embodiment 1 oral english teaching use adjustable ear muff, the ring piece outer wall be fixed with plectrum 9, the plectrum be located the recess 11 of headset seat in, the kinematic position of plectrum is recess one side to the opposite side of recess, the rotation through the ring piece realizes that the stationary blade tip contacts with the different positions on slope, realize the slip of branch, because the rubber circle has elasticity, can realize that the grow of rubber circle diminishes, thereby be applicable to the teacher and the student of different ear sizes, shape, the connection form of rubber circle is lower extreme and interior crown plate bottom bonding, then walk around the circular arc piece, the other end and the limiting plate bonding of rubber circle, wherein still bond with interior crown plate, including can realizing all enclosing each part of ear muff, prevent to expose.
