A sound receiver 207 is arranged on the top of the protection box 1, and two loudspeakers 102 are symmetrically fixedly embedded on the outer surface of the protection cover 101, two female buckles 103 are symmetrically fixedly installed on one side of the protection box 1, and two sub-buckles 104 are symmetrically fixedly installed on one side of the protection cover 101, a handle 106 is fixedly installed on one side of the protection box 1, and an elastic sponge pad 105 is fixedly installed on the bottom of the inner wall of the protection box 1.

[0028] In this embodiment, the protective cover 101 is pulled upward so that it rotates with the cooperation of the hinge, and the movable rod 2 is rotated around the fixed rod 213 and the movable rod 201 is rotated around the fixed rod 214 simultaneously, so that the angle between the movable rod 2 and the movable rod 2 is gradually increased. When the movable rod 2 and the movable rod 2 are on the same horizontal line, the protective cover 101 is unfolded to the maximum extent, and the unfolding angle of the protective cover 101 is greater than 90 degrees. Under the action of gravity, the protective cover 101 can apply a pulling force to the movable rod 2 and the movable rod 201, so that the protective box 1 and the protective cover 101 are kept in a relatively fixed state. With the cooperation of the mother buckle 103 and the child buckle 104, the protective box 1 and the protective cover 101 can be combined together, and then the elastic sponge pad 105 is provided to play a certain protective role to prevent the microphone 207 from being damaged by collision.

[0029] Embodiment 2, as Figure 1-5 As shown, the outer surface of the round rod 202 is movably sleeved with a sleeve rod 203, and the outer surface of the sleeve rod 203 is fixedly sleeved with two hollow rods 204, and the interiors of the two hollow rods 204 are slidably connected with slide rods 205, and one side of the two slide rods 205 is fixedly installed with a connecting plate 206, and one side of the connecting plate 206 is fixedly installed at one end of the receiver 207, and one side of the two slide rods 205 is equidistantly opened with a plurality of adjustment holes 209, and the two hollow rods 204 are threadedly embedded with screws on the side away from the sleeve rod 203. 208, one end of the two screw rods 208 is movably embedded in the inside of two of the adjustment holes 209, and both ends of the sleeve rod 203 are fixedly installed with multiple elastic sheets 212 in a circular array, and the multiple elastic sheets 212 are evenly divided into two groups. The outer surface of the round rod 202 is symmetrically threaded with two locking rods 210, and one end of the inner wall of the two locking rods 210 is movably sleeved on the outer surface of the two groups of elastic sheets 212, and the ends of the two locking rods 210 away from the sleeve rod 203 are fixedly sleeved with knobs 211.

[0030] In this embodiment, the sleeve rod 203 is manually rotated to adjust the microphone 207 to a suitable tilt angle, and then the knob 211 is manually rotated to drive the locking rod 210 to rotate. Then, under the action of the threaded cooperation between the locking rod 210 and the round rod 202, the locking rod 210 can be moved to one side and the elastic sheet 212 can be squeezed to make the elastic sheet 212 fit tightly with the outer surface of the round rod 202, so that the sleeve rod 203 and the round rod 202 can be kept in a relatively fixed state, and then the screw rod 208 is manually rotated to make it move from one of the adjustment holes 209 to the other side.

Under the action of gravity, the protective cover 101 1 can apply a pulling force to the movable rod 1 2 and the movable rod 201, so that the protection box 1 and the protection cover 101 are kept in a relatively fixed state. At this time, according to the use requirements, the sleeve rod 203 is rotated to adjust the sound receiver 207 to a suitable tilt angle, and then the knob 211 is manually rotated to drive the locking rod 210 to rotate. Then, under the action of the threaded cooperation between the locking rod 210 and the round rod 202, the locking rod 210 can be moved to one side and the elastic sheet 212 can be squeezed to make the elastic sheet 212 and the round rod 202 rotate. The outer surface of the round rod 202 fits tightly, so that the sleeve rod 203 and the round rod 202 can be kept in a relatively fixed state, and then the screw rod 208 is manually rotated to disengage it from the inside of one of the adjustment holes 209, thereby releasing the limit on the slide rod 205. At this time, the slide rod 205 can be slid outward along the inside of the hollow rod 204, so that the distance between the sound receiver 207 and the teacher can be adjusted, which is convenient for the sound receiver 207 to receive sound, and then the screw rod 208 is rotated in the opposite direction to insert it into the inside of the other adjustment hole 209, so as to limit the slide rod 205, so that the sound receiver 207 is kept in a suitable position, so that the height and angle of the sound receiver 207 can be properly adjusted, so as to facilitate the sound receiver 207 to receive sound, thereby improving the teaching effect of the teacher, and with the cooperation of the mother buckle 103 and the child buckle 104, the protective box 1 and the protective cover 101 can be combined together, and then the elastic sponge pad 105 is set to play a certain protective role to prevent the sound receiver 207 from being damaged by collision.
