Problems solved by technology

[0005] The size of the above-mentioned earphones cannot be adjusted according to the wearer's head circumference, so it is not convenient to use and has a small scope of application. In the prior art, there are also some earphones that can be adjusted in size through frictional damping between the support frame and the connecting rod, but after adjustment, Although people with small heads can barely wear it, the bottom of the earphones will be warped and deformed, and the fit between the earmuffs and the ears is poor, making it not comfortable to wear;

Abstract

The invention relates to the technical field of listening training devices, and discloses a listening training device for Russian teaching, which comprises a left side beam and a right side beam, the top of the left side beam is fixedly provided with a first connecting block, and the top of the right side beam is fixedly provided with a second connecting block. The first connecting block and the second connecting block are both movably arranged in the control box, and a control mechanism arranged in the control box drives the first connecting block and the second connecting block to be close to each other or away from each other. A first nut and a second nut can get close to each other or get away from each other by screwing the first knob, when the first nut and the second nut get close to each other, the left side beam and the right side beam can get close to each other through the first connecting block and the second connecting block so as to be suitable for students with small head circumference, and when the first nut and the second nut get away from each other, the left side beam and the right side beam can be far away from each other through the first connecting block and the second connecting block so as to be suitable for students with large girths.
