Auxiliary device for English listening training

Abstract

The invention relates to the field of English learning tools, particularly relates to an auxiliary device for English listening training. The auxiliary device comprises an adjusting frame and two earmuffs, a first rack and a second rack which are arranged in parallel are slidably connected into the adjusting frame. The ends, located on the outer side of the adjusting frame, of the first rack and the second rack are fixedly connected with arc-shaped frames respectively, telescopic mechanisms are arranged at the lower ends of the two arc-shaped frames, the two earmuffs correspond to the telescopic mechanisms, adjusting boxes are fixed to the upper ends of the earmuffs, and the lower ends of the telescopic mechanisms are arranged in the corresponding adjusting boxes. The auxiliary device forEnglish listening training is suitable for people with different head circumference sizes; when the two earmuffs move, the shapes of the earmuffs are kept unchanged; the adjustable earmuff is simple and convenient to operate, the angle between the earmuff body and the plane where the ears are located is adjusted through the adjusting box, the earmuff body can be parallel to the plane where the ears are located, the earmuff body can be tightly attached to the ears, external noise transmission is reduced, and the hearing training level can be improved.

Description

technical field [0001] The invention relates to the field of English learning appliances, in particular to an auxiliary device for English listening training. Background technique [0002] During English listening training, earphones are usually used for hearing training. The existing headsets are usually adjustable, but the existing headsets are adjusted because their adjustment frames are arc-shaped, so the size of the head circumference will be adjusted. The arc-shaped movement track of the two earmuffs is widened or narrowed, so that the fit between the earmuffs and the ear is not high, which often causes the ear base to receive a large squeezing force, causing discomfort, and The surface where the earmuffs are located is not parallel to the surface where the ear parts are located, forming a certain angle that leads to a low fit between the earmuffs and the ear beads, which makes it easy to be disturbed by external noise during listening training, which is not conducive ...

[0002] During English listening training, earphones are usually used for hearing training. Existing earphones are usually adjustable. The arc-shaped movement track of the two earmuffs is widened or narrowed, so the fit between the earmuffs and the ear is not high, which often causes the ear base to receive a large squeeze, causing discomfort, and The surface where the earmuffs are located is not parallel to the surface where the ears are located, forming a certain angle, which leads to a low fit between the earmuffs and the earballs, which makes it easy to be disturbed by external noise during hearing training, which is not conducive to the improvement of hearing training. In view of Therefore, we propose an auxiliary device for English listening training
