With continued reference to fig. 2, the entirety of the second noise reduction section 222 may extend in only one direction, i.e., the second noise reduction section 222 is of a one-piece structure; of course, as shown in fig. 3, the second noise reduction section 222 may also be composed of a plurality of sections connected to each other, and the extension direction of each section may be different. With continued reference to fig. 2 and 3, in an embodiment of the present application, an end of the noise reducer 22 away from the sound outlet channel 212 extends out of the accommodating cavity 211, and an end of the cap body 21 away from the sound outlet channel 212 abuts against an outer side wall of the noise reducer 22. The noise reduction piece 22 can be supported by the end of the ear cap body 21 far away from the sound outlet channel 212, so that the noise reduction piece 22 is not easy to deform, meanwhile, the end of the ear cap body 21 far away from the sound outlet channel 212 is tightly contacted with the outer side wall of the noise reduction piece 22, the sealing performance of the noise reduction cavity 30 is ensured, and the noise reduction piece 22 is convenient to assemble and disassemble when the noise reduction piece 22 is detachable; the length of the end of the noise reducing member 22 away from the sound outlet channel 212 extending out of the accommodating cavity 211 can be selected according to actual requirements.

As shown in fig. 4, the noise reducing member 22 may also be located in the accommodating cavity 211, and one end of the noise reducing member 22 away from the sound outlet channel 212 abuts against an inner side wall of the earcap main body 21, so as to prevent the edge of the noise reducing member 22 from tilting to cause sealing failure of the noise reducing cavity 30 in the use process of the earphone body 10.

It should be noted that fig. 2 to 4 only illustrate the case where the connection between the contact portion 213 and the sound emitting portion 214 protrudes outward, and as shown in fig. 5, the connection between the contact portion 213 and the sound emitting portion 214 may be designed as a throat.

Specifically, as shown in fig. 5, the connection between the contact portion 213 and the sound emitting portion 214 is recessed inward; it should be noted that, referring to fig. 5, when the sound outlet tube 11 with the ear cap assembly 20 mounted thereon is inserted into the ear canal, the sound outlet portion 214 is located at the front end of the ear cap assembly 20, and therefore, the sound outlet portion 214 is located at a deeper position in the ear canal, in the present application, the contact portion 213 is used to ensure the sealing property when the sound outlet tube 11 is inserted into the ear canal, and on the premise of not affecting the normal use of the ear cap assembly 20, the connection portion between the contact portion 213 and the sound outlet portion 214 is designed to be a reduced mouth, so as to form a structure similar to a nipple shape, which can reduce the contact area and the extrusion amount between the sound outlet portion 214 and the ear canal, reduce the invasion feeling of the ear cap assembly 20 to the ear canal, and improve the comfort of entering the ear.

It should be noted that, referring to fig. 5, the curvature of the outer contour of the longitudinal section of the contact portion 213 is greater than the curvature of the outer contour of the longitudinal section of the sound emitting portion 214, that is, the outer side surface of the sound emitting portion 214 is curved to a greater extent in the sound emitting direction than the outer side surface of the sound emitting portion 214, so that the outer diameter of the contact portion 213 is reduced to a greater extent in the sound emitting direction than the outer diameter of the sound emitting portion 214, and an inwardly concave structure can be formed at the connection between the contact portion 213 and the sound emitting portion 214.

Specifically, the outer diameter of the sound emitting portion 214 is arranged to decrease in the direction from the contact portion 213 to the sound emitting portion 214, and it can be understood that the smaller the outer diameter of the region of the sound emitting portion 214 that is farther from the contact portion 213, the smaller the outer diameter of the connection portion between the sound emitting portion 214 and the contact portion 213 is, the maximum outer diameter of the sound emitting portion 214, so that when the sound emitting tube 11 with the earcap assembly 20 mounted thereon is inserted into the ear canal, the smaller the outer diameter of the sound emitting portion 214 that is inserted deeper into the ear canal is, which can further reduce the intrusion feeling of the earcap assembly 20 into the ear canal and improve the comfort of the ear.

It should be noted that the outer side surface of the sound emitting portion 214 may be a curved surface or an inclined plane, when the outer side surface of the sound emitting portion 214 is an inclined plane, an included angle formed between the outer side surface of the sound emitting portion 214 and the sound emitting direction of the ear cap assembly 20 may be 15 degrees to 20 degrees, and an included angle formed between the outer side surface of the sound emitting portion 214 and the sound emitting direction of the ear cap assembly 20 may be 15 degrees, 17 degrees, 18 degrees, 20 degrees, or the like; when the included angle formed by the outer side surface of the sound outlet part 214 and the sound outlet direction of the ear cap assembly 20 is too small, the maximum outer diameter of the sound outlet part 214 is large, so that the ear canal is strongly extruded; when the angle formed by the outer side surface of the sound outlet 214 and the sound outlet direction of the ear cap assembly 20 is too large, the maximum outer diameter of the sound outlet 214 is too small, which may result in the size of the sound outlet 212 becoming small, and the sound outlet 212 may be easily closed when the sound outlet 214 is squeezed.

In an embodiment of the present application, the outer diameter of the contact portion 213 decreases along the direction from the contact portion 213 to the sound emitting portion 214, that is, the outer diameter of the region of the contact portion 213 closer to the sound emitting portion 214 is smaller, so as to reduce the contact area and the amount of squeezing between the contact portion 213 and the ear canal, reduce the intrusion feeling of the earcap assembly 20 to the ear canal, and improve the comfort in the ear, at this time, the outer diameter of the connection portion of the contact portion 213 and the sound emitting portion 214 is the minimum outer diameter of the contact portion 213, and the outer side surface of the contact portion 213 may be a curved surface or an inclined plane.

Of course, the outer diameters of the contact portions 213 may all be the same along the direction of the contact portions 213 toward the sound emitting portion 214 to improve the sealing performance of the ear cap assembly 20 in the ear canal.

With continued reference to fig. 5, in some embodiments of the present application, the outer diameter of the connection between the contact portion 213 and the sound emitting portion 214 is d1, and d1 is 6 mm to 7 mm. d1 may be 6 mm, 6.5 mm, 7 mm, or the like. d1 is too large, so that the auditory meatus is strongly extruded, and discomfort of a user is caused; on the other hand, if d1 is too small, the size of the sound outlet 212 becomes small, and the sound outlet 212 is easily closed when the sound outlet 214 is pressed.

With continued reference to fig. 5, in some embodiments of the present application, contact portion 213 is in smooth-transition connection with sound emitting portion 214.

The present invention is not intended to be limited to the particular embodiments shown and described, but is to be accorded the widest scope consistent with the principles and novel features herein disclosed.
