In order to more vividly explain the earphone sleeve of the present application, another aspect of the embodiments of the present application provides an earphone, please refer to fig. 1 to 4, including a housing 1 and an earphone sleeve 2. Specifically, the casing 1 is made of hard glue material, and the earphone sleeve 2 is made of soft glue material.

Taking a bean-type in-ear TWS earphone as an example, the outer surface of the housing 1 includes a main body region 11 and an ear-attached region 12 located at one side of the main body region 11. Specifically, the housing 1 has a hollow shell structure, and the ear region 12 is a region on one side of the outer surface of the housing 1 that contacts the ear in a state where the earphone is worn on the ear. The body region 11 refers to a side region of the outer surface of the casing 1 not in contact with the ear.

The earphone sleeve 2 includes a housing portion 21 formed with a housing cavity 21 a. One side of the sleeve part 21 is formed with a sleeve opening 21b communicated with the sleeve cavity 21a, and the sleeve part 21 is sleeved on the ear region 12 through the sleeve opening 21 b. That is, the engaging portion 21 is a hollow structure having an engaging cavity 21a, and the engaging opening 21b is used for engaging with the ear region 12 of the housing 1.

According to the earphone provided by the embodiment of the application, the sleeve part 21 capable of coating the ear sticking area 12 is arranged on the earphone sleeve 2, so that the ear sticking area 12 on one side of the casing 1 is coated by the sleeve part 21 made of the soft rubber material. On the one hand, when the wearer wears the earphone, the ear contacts the soft texture nesting part 21 instead of the hard glue structure with the hard texture on the outer surface of the casing 1, the soft glue material can not extrude the ear, and the ear is not easy to swell and pain after being worn for a long time, so that the wearing comfort of the wearer is greatly improved. On the other hand, the surface contact area between the earphone sleeve 2 and the casing 1 is increased by the sleeve part 21, so that the earphone sleeve 2 is more firmly attached to the casing 1 and is not easy to fall off.

It should be noted that the earphone sleeve 2 of the present application can be used for a bean-type in-ear TWS earphone, a rod-type in-ear TWS earphone, and other earphones having an ear patch 12 on the housing 1.

The housing 1 includes but is not limited to hard glue materials such AS PS (Polystyrene), ABS (Acrylonitrile Butadiene Styrene), AS (Acrylonitrile Styrene) and PVC (Polyvinyl chloride) plastics.

The earphone sheath 2 includes, but is not limited to, soft rubber materials such as rubber, silicone or TPU (Thermoplastic polyurethanes).

In one embodiment, referring to fig. 1 to 4, the ear region 12 is formed with a sound outlet 12a, and the earphone sleeve 2 includes an earphone portion 22 connected to the other side of the sleeve portion 21. Specifically, the earplug portion 22 is formed with a sound outlet passage 22a, and the sound outlet 12a communicates with the sound outlet passage 22 a. When the earphone sleeve 2 is not sleeved on the casing 1, the sleeve cavity 21a is open at one side communicating with the sound outlet channel 22a, when the ear-fitting region 12 is sleeved in the sleeve cavity 21a, the sound outlet 12a is in butt communication with the sound outlet channel 22a, and the earplug part 22 extends into the ear, so that the sound output from the sound outlet 12a can be smoothly transmitted to the ear through the sound outlet channel 22 a.

For example, in one embodiment, referring to fig. 1-4, the earplug portion 22 includes a sound outlet segment 221 and an ear inlet segment 222. The sound outlet section 221 is formed with a sound outlet channel 22a, one end of the sound outlet section 221 is connected with one end of the nesting portion far away from the sleeve joint 21b, the ear inlet section 222 is an annular structure surrounding the periphery of the sound outlet section 221, and one end of the ear inlet section 222 is connected with one end of the sound outlet section 221 far away from the nesting portion 21. Specifically, the sound outlet section 221 is an annular structure having a sound outlet channel 22a with openings at two sides, and when the ear-adhering region 12 is sleeved in the sleeving cavity 21a, the sound outlet 12a is located at an opening of the sound outlet channel 22a at a side close to the sleeving opening 21 b. One end of the ear-in section 222 is connected to the outer ring surface of the sound-out section 221, which is open at the side away from the socket 21b, and the other end of the ear-in section 222 is a split ring.

The sound outlet section 221 is used for constructing the sound outlet channel 22a, so that sound can be smoothly transmitted to the ear through the sound outlet channel 22a, the ear inlet section 222 is used for attaching to the inner peripheral wall of the ear, when a wearer wears the earphone, the outer annular wall of the ear inlet section 222 is in contact with the inner peripheral wall of the ear and then is elastically deformed, and the elastic restoring force generated by the elastic deformation enables the ear inlet section 222 to abut against the inner peripheral wall of the ear. Therefore, on one hand, the ear-entering section 222 can isolate most external noise after being tightly attached to the inner peripheral wall of the ear, so that the noise reduction effect of the earphone is improved. On the other hand, the friction between the ear insertion section 222 and the inner peripheral wall of the ear can make the wearing more secure and not easy to loosen.

Illustratively, the sleeve portion 21 and the ear plug portion 22 of the earphone sleeve 2 are an integrally formed structure, and the integrally formed structure can make the structure surface of the earphone sleeve 2 seamless, so as to improve the comfort level of the wearer when wearing the earphone sleeve.

In one embodiment, the wall thickness of the engaging portion 21 is smaller than that of the sound emitting section 221. That is to say, the sound output section 221 has a relatively thick wall and a relatively high structural strength, so that the sound output channel 22a in the sound output section 221 can maintain a relatively good contour shape after the wearer wears the earphone, and smooth transmission of sound to the ear can be ensured.

In one embodiment, referring to fig. 1 to 4, the engaging portion 21 is detachably connected to the housing 1. That is, the engaging portion 21 can be engaged with and covered on the ear region 12, or can be detached from the ear region 12. Because the sizes of the outline sizes of the ears of each wearer are different, the wearing requirements of different wearer groups can be met by designing a plurality of earphone sleeves 2 with the same size of the nesting parts 21 and different sizes of the earplug parts 22. Therefore, the sleeve part 21 and the casing 1 are detachable, so that the earphone sleeves 2 of different specifications and sizes of the earphone plug parts 22 can be conveniently replaced to adapt to the contour size of the ears of each wearer.

In an embodiment, referring to fig. 1 to 4, a first clamping portion 21c is formed on an inner peripheral surface of the fitting cavity 21a, the first clamping portion 21c is used for clamping with a second clamping portion 121 of the ear attaching area 12, and the second clamping portion 121 is clamped with the first clamping portion 21 c. The clamping structure is simple in form and firm in connection, a wearer can detach the earphone sleeve 2 without tools, and the earphone sleeve can be conveniently replaced by the wearer when necessary.

Specifically, in an embodiment, referring to fig. 1 to 4, one of the second fastening portion 121 and the first fastening portion 21c is a fastening projection, and the other is a fastening slot, and the fastening projection is embedded in the fastening slot. That is, when the tab portion 12 is formed with a tab protruding outward, the inner peripheral surface of the fitting cavity 21a is formed with a slot matching with the tab; when the lug attaching region 12 is formed with an inward recessed clamping groove, a clamping protrusion matched with the clamping groove is formed on the inner circumferential surface of the sleeve cavity 21a; the clamping convex is embedded in the clamping groove. The clamping groove and the clamping protrusion are matched, so that the connection reliability between the shell 1 and the earphone sleeve 2 can be improved, and the earphone sleeve 2 can be prevented from falling off along the sound outlet 12a when being worn.

In an exemplary embodiment, referring to fig. 1 to 4, the locking protrusions are disposed on the periphery of the sound outlet 12a of the ear-contacting area 12, and the locking grooves are disposed on the inner peripheral wall of the matching cavity 21a and located at the junction of the matching cavity 21a and the sound outlet channel 22 a.

In one embodiment, referring to fig. 1 to 4, the ear region 12 is recessed toward the inside of the housing 1. That is to say, the wall thickness of the ear adhering region 12 of the casing 1 is thinner than the wall thickness of the main body region 11 so as to adapt to the thickness of the engaging portion 21 of the earphone sleeve 2, so that when the engaging portion 21 of the earphone sleeve 2 is engaged with and wrapped on the ear adhering region 12, the outer peripheral wall of the engaging portion 21 does not protrude outwards relative to the main body region 11, and thus the earphone still has a smooth appearance after the earphone sleeve 2 is assembled.

In an embodiment, referring to fig. 1 to 4, the earphone sleeve 2 is an elastic structure, after the inner circumferential surface of the engaging cavity 21a is covered on the ear adhering region 12, the ear adhering region 12 can stretch the inner circumferential surface of the engaging cavity 21a, so that the elastic restoring force of the engaging cavity 21a makes the engaging portion 21 tightly adhere to the ear adhering region 12. That is, after the earphone sleeve 2 is assembled to the casing 1, the elastic restoring force of the earphone sleeve 2 itself can increase the frictional resistance with the casing 1, thereby helping the earphone sleeve 2 to be more firmly attached to the casing 1.

In an exemplary embodiment, the interference between the inner peripheral surface of the registration cavity 21a and the ear region 12 is 0.3mm. Specifically, referring to fig. 1 to 4, the fitting interference D1 is 0.3mm, so as to ensure a moderate frictional resistance between the fitting cavity 21a and the ear region 12.

Illustratively, in one embodiment, the wall thickness of the nesting portion 21 is 0.5mm. Specifically, referring to fig. 1 to 4, the wall thickness D2 of the sheathing part 21 is 0.5mm, so that the earphone sheath 2 is light and thin while ensuring flexibility.

In one embodiment, the inner periphery of the registration cavity 21a and the ear area 12 are mirror surfaces. In particular, the mirror may be a high-gloss mirror; highlight mirror surface can make the inner peripheral surface of registrate chamber 21a and the roughness of sticking to ear district 12 low, the two cooperation precision is high, especially when earphone sleeve 2 is the silica gel material, the silica gel material has certain adhesive force with the surperficial adhesion of highlight mirror surface, the assembly back, the adhesive force between the inner peripheral surface of registrate chamber 21a and the sticking to ear district 12 for registrate chamber 21a and sticking to ear district 12 tightly together, thereby prevent that earphone sleeve 2 from droing.

Illustratively, in one embodiment, the inner peripheral surface of the registration cavity 21a and the ear region 12 each have a surface roughness value of less than 0.05 μm.

In one embodiment, referring to fig. 1 to 4, the housing 1 includes a middle shell 13, a rear shell 14 and a speaker cover 15.
