The brace rod 83 is the arc, and brace rod 83 perpendicular to earmuff 8's internal perisporium axis, brace rod 83's length are the third to half of gasbag 81 cross-section girth, and this makes brace rod 83 can wrap ring section of thick bamboo 84 towards the half arc surface of front shroud 5, has increased the cavity volume in sound generating unit 4 the place ahead, and great cavity volume is insensitive to the response of air pressure, reduces the impaired possibility of eardrum and also reduces sound generating unit 4 sound membrane because air pressure vibrates unusually, subducts the noise.

The number of the support ribs 83 is plural, and the support ribs 83 are annularly arrayed below the inner side surface of the ring cylinder 84.

Preferably, since the human auricle forms an angle of 15 ° to 25 ° with the side of the head, the spiral angle of the connecting groove 61 is β =65 ° to 75 °, an angle such as 65 °, 68 °, 70 °, 72 °, 75 °, preferably 70 ° to 72 ° may be used, and the angle formed by the perpendicular plane to the axis of the rear shell 6 and the connecting groove 61 is α =15 ° to 25 °, when the sound-emitting portion 3 is connected to the connecting claw 9, because of the rotation angle of the connecting groove 61, the two sound-emitting portions 3 are "eight" shaped and just parallel to the auricle, the sound-emitting portion 3 does not press the auricle too much, and the pressing of the auricle by the small-angle torsion of the sound-emitting portion 3 due to the clamping force of the headband 1 can also be compensated by the air transfer in the air bag 81.

The radian of the elastic plate 91 is greater than the radian of the arc of the rear shell 6, when the elastic plate 91 is connected to the connecting groove 61 through the elastic claw 92, the middle part of the elastic plate 91 presses on the surface of the rear shell 6, the two ends of the elastic plate are tilted upward, so that the joint of the frustum 923 and the pillar 921 is abutted on the top surface of the inner groove 612, and the first tooth 613 is engaged with the second tooth 922, thereby fixing the relative position of the rear shell 6 and the connecting claw 9.

The height of the inner groove 612 is greater than the sum of the heights of the frustum 923 and the second tooth 922, the height of the outer groove 611 is less than the difference between the heights of the support 921 and the second tooth 922, the diameter of the bottom surface of the frustum 923 is greater than the width of the outer groove 611 and less than the width of the inner groove (612), the elastic claw 92 is moved into the connecting groove 61 by pressing the two ends of the elastic plate 91 downwards, because the height of the outer groove 611 is less than the difference between the heights of the column and the second tooth 922, the second tooth 922 is separated from the first tooth 613 when the elastic claw 92 moves inwards, the positions of the elastic claw 92 and the connecting groove 61 are not limited, at this time, the rear shell 6 can be rotated to adjust the advance or retreat of the sound generating part 3 on the telescopic rod 2, so as to adjust the distance between the two sound generating parts 3, control the clamping force, and be comfortable to use.

When the earphone is worn on the head, the openings of the eight shapes of the two sound-emitting parts 3 are backward and buckled on the ears, if the tightness needs to be adjusted, only two ends of the elastic plate 91 need to be pressed, the elastic claw 92 is enabled to move towards the connecting groove 61, because the height of the outer groove 611 is smaller than the difference between the heights of the support 921 and the second tooth 922, therefore, the second tooth 922 is separated from the first tooth 613 along with the inward movement of the elastic claw 92, the positions of the elastic claw 92 and the connecting groove 61 are not limited any more, at this time, the rear shell 6 can be rotated to adjust the advancing or retreating of the sound-emitting parts 3 on the telescopic rod 2, so as to adjust the distance between the two sound-emitting parts 3 and control the tightness.

In the hearing training process, the air outlet 51 arranged on the front cover plate 5 of the earphone can be communicated with the two sides of the front cover plate 5, the air flow pressure generated by vibration at the two sides of the sound film of the sound generating unit 4 is balanced, and the sound film is prevented from generating noise.

The preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various modifications can be made to the technical solution of the present invention within the scope of disclosure without departing from the spirit of the present invention.
