Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

Example 1

A headset for listening to foreign language teaching, as shown in fig. 1, includes an ear mount 1, a headset housing 2, an earpiece 4, and an ear muff 5 (fig. 4). As shown in fig. 4, the earmuffs 5 surround the earpieces 4, cotton pads 3 are arranged on the earmuffs 5, the cotton pads 3 are annular, and the cotton pads 3 are detachably connected with the earmuffs 5.

Example 2

Further improve, ear muff 5 includes fixed part 6 and sets up the clamping part 7 in the fixed part both sides, be provided with cavity 8 on the clamping part 7, the mobilizable setting of fly leaf 9 is in cavity 8, the one end and the spring 10 of fly leaf 9 are fixed, spring 10 fixes in cavity 8, set up stripper plate 15 in the other end of fly leaf 9 and the fly leaf 9 vertically direction, logical groove 12 has been seted up to the side of clamping part 7, logical 12 internal fixation has bracing piece 13, the free end of bracing piece 13 is provided with joint 14, one side of fly leaf 9 is provided with first arch 11, the opposite side sets up second arch 16, first arch 11 uses with the joint 14 cooperation. The first protrusion 11 and the second protrusion 16 are annular. The working mode of the embodiment is as follows: as shown in fig. 4, 5 and 6, when the cotton pad 3 is installed, the clamping portion 7 is in the state shown in fig. 6, that is, the first protrusion 11 is located at the left side of the clamping head 14, the spring 10 is in a free extension state, the supporting rod 13 and the clamping head 14 are in a free state, the cotton pad 3 is inserted between the two movable plates 9, the cotton pad 3 can be conveniently inserted into the movable plates 9 due to the deformable state of the cotton pad 3, and the cotton pad 3 is unfolded; the pressing plate 15 is pressed, under the action of pressure, the first bulge 11 passes over the clamping joint 14, and the second bulge is supported on the wall of the cavity 8 and plays a supporting role; due to the elasticity of the rod body of the support rod 13, the clamping joint 14 is kept in contact with the first protrusion 11, and the position is fixed, as shown in fig. 8. When the cotton pad 3 needs to be replaced, as shown in fig. 10, the clamping joint 14 has a portion exposing the clamping portion 7, the clamping joint 14 is pulled outward by hand to cause the supporting rod 13 to deform, the movable plate 9 is pushed outward under the action of the elastic force of the spring 10, so that the squeezing of the squeezing plate 15 and the cotton pad is released, the cotton pad 3 is released, and the cotton pad 3 is pulled outward by hand.
