Referring to fig. 6 and 7 together, fig. 6 is a schematic sectional view of a partial structure of another embodiment of the earphone of the present application, and fig. 7 is a schematic structural view of another embodiment of an earphone cap. The structure of the earphone cap in this embodiment omits the description of the structures such as the control circuit board and the wireless induction coil (and the structures are not shown in the drawings), while the structure of the earphone head related to wireless receiving of electric energy is omitted, and the description is only made for the acoustic problem of the earphone cap and the earphone head casing matching. The earphone is improved in the aspect of acoustics in the wearing process, the middle sound adjusting cavity 101 is arranged mainly from the design angle of the acoustic cavity, a small-volume cavity is formed around the loudspeaker 120, and the sound in different frequency bands is effectively enhanced or weakened through adjusting the air damping of the sound adjusting hole 1112.

The wearing comfort of human ears is affected by many aspects, and the acoustic effect is only one of them, for the above-described scheme, the way of forming the sound insulation cavity 202 by arranging the groove (the area formed between the inner ear cap 210 and the outer ear cap 220) at the top of the earphone cap can be improved to some extent in terms of sound effect, but the earphone cap 200 has a smaller size, the processability of the sound insulation cavity 202 at the top is deviated due to the weaker wall thickness of the outer ear cap 220, and the dimensions such as groove depth and groove distance are smaller, which is inferior in uniformity control, and in a complicated use scene, the possibility that the ear canal and the ear wall of a user contact the groove in a friction manner is not eliminated, thereby causing wearing discomfort, and in addition, the problems of difficulty and uniformity of molding processing exist. Therefore, many patents focus on adjusting and controlling acoustics from an acoustic cavity structure, devices such as a microphone and a loudspeaker stack, and the sounding of the acoustics needs to be transmitted out through the earphone cap 200, so that the earphone cap 200 can be conveniently and quickly adjusted and verified without increasing the cost by improving the design, but the size of the earphone cap 200 limits the design of a complex structure, otherwise, the processing and consistency are worse. Therefore, a method is needed, the ear cap is designed, acoustic and wearing comfort requirements are guaranteed, and the ear cap is easy to realize and produce in mass.

In view of this, the length of the outer ear cap 220 in this embodiment ranges from 0.7 cm to 1.5 cm; the length of the outer ear cap 220 is the distance from the end of the outer ear cap 220 connected to the first end of the inner ear cap 210 to the end near the second end of the inner ear cap 210, i.e. the distance between the points X and Y in fig. 6. The size is shorter compared with the length of the outer ear cap in the conventional art (the length of the outer ear cap in the conventional art is generally more than 1.6 cm). Also reduce the shirt rim (outer ear cap) of conventional earphone cap by 0.1-0.8mm height, because the shirt rim height reduces when going into the ear, have bigger space behind the contact duct skin to take place to warp and the action of pasting the ear, so the laminating nature is better, and does not contact casing 110 (for preceding shell 111 in this embodiment) at this in-process, has avoided producing the noise behind the contact earphone shell, thereby produces annex oppression power etc. to the ear canal to produce the resilience force. When the height of the skirt edge is reduced too small, the risk that the outer ear cap 220 contacts the front shell 111 is increased, abnormal sound is generated, the actual experience effect is poor, and when the height of the skirt edge is reduced too large, the gravity center of the outer ear cap 220 can be moved forwards to the top of the earphone cap 200, so that the structure is unstable, the outward turning is easy to generate, and the sealing performance is poor. Optionally, the length of the external ear cap 220 in the embodiment of the present application may be in a range of 0.8-1.4cm, and within this range, the external ear cap 220 may be prevented from contacting the front shell 111, and abnormal sound is avoided; the gravity center of the outer earcap 220 can be prevented from moving forward to the top of the earphone cap 200, so that the problems of unstable structure, easy eversion and poor sealing performance are avoided.

Referring to fig. 8, fig. 8 is a schematic structural view of the earphone cap in another view in the embodiment of fig. 7; normally, the diameter of the auditory canal can accommodate an index finger, which is about 12-15mm, after subtracting the diameter of the earphone head (namely the inner earcap 210) from 6-8mm, a gap of 3-4 mm is arranged on one side, and then the wall thickness of the outer earcap 220 is subtracted from about 0.6mm, so that the maximum gap h between the inner earcap 210 and the outer earcap 220 is 2.4-3.4mm, if the size of the gap h is continuously increased, the interference between the skin of the auditory canal and the elastomer is increased, and the discomfort is increased; however, if the gap h is less than 0, the inner wall of the external ear cap 220 collides with the front case 111 and cyclically collides with the front case by the movement, which causes frictional noise, and it is not preferable to change the tone hole 1112 without any gap. When generally wearing the earphone, external ear cap 220 contacts the ear canal area and occupies 40% -60% of the whole, and is unstable for short, can produce discomfort because of the leakproofness is too strong for the overlength, and conventional technique is generally 70% -90%, and technical scheme in the embodiment of this application reduces the length through external ear cap 220 to be 0.8-1.4cm for the regional suitable amount that contacts the ear canal reduces to 40% -60%, under the condition of not having the influence wearability, can solve abnormal sound and the unstable problem of structure.

According to the earphone provided by the embodiment, the earphone cap structure reduces the design of the outer ear cap (namely the skirt edge of the ear cap) (the length of the outer ear cap is generally more than 1.6cm in the conventional technology), so that when the ear cap is inserted into an ear canal, the wall edge of the outer ear cap is difficult to directly contact with an earphone shell, collision friction noise is reduced, meanwhile, the skirt edge is better in fit with the ear canal, and the wearing comfort is improved; in addition, the wall edge of the outer ear cap can be prevented from blocking the sound adjusting hole, and the acoustic effect of the earphone is further improved.

Further, with reference to fig. 6 to 8, the inner sidewall of the external ear cap 220 in the present embodiment is provided with a plurality of first supporting protrusions 230, and the plurality of first supporting protrusions 230 may be uniformly and symmetrically arranged along the circumference of the inner sidewall of the external ear cap 220.

Alternatively, the first supporting protrusion 230 may be an elongated reinforcing rib, and the long axis direction is along the umbrella-shaped arc direction of the outer ear cap 220, i.e. along the inner ear cap edge toward the first end of the inner ear cap. The first support protrusion 230 is higher near the skirt (the hanging end of the outer ear cap 220, i.e., the rim of the outer ear cap 220) and gradually lower in height toward the top of the outer ear cap 220. This kind of project organization, receive the ear canal extrusion back at outer earcap 220, take place to warp, under the condition of the design of first support protrusion 230 not, it is irregular that outer earcap 220 warp to appear easily, it is good but block up sound adjusting hole 1112 easily to paste the ear sensation, the effect that leads to sound is experienced and is worsened, earcap structural design in this embodiment, when earphone cap 200 injects the ear deformation, first contact casing (the preceding shell 111) be not outer earcap 220, but a lot of evenly distributed's first support protrusion 230, first support protrusion 230 can be for flexible glue or flexible battery material. The first supporting protrusion 230 is deformed and rebounded after being pressed, so that the outer ear cap 220 is prevented from completely clinging to the earphone shell and leaving the corresponding gap 102, the sound of the sound adjusting hole 1112 can be exchanged through the gap 102, and the acoustic effect is improved under the condition of ensuring wearing and jointing. It is noted that in the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically defined otherwise. All directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.

In the earphone cap structure of the present embodiment, the first supporting protrusion 230 is located on the inner wall of the outer ear cap 220, and the function of the outer ear cap 220 that does not block the sound adjusting hole 1112 is preferably implemented. Because the protruding gas leakage of making an uproar falls passively can be caused to the arch of first support arch 230, and outer ear cap 220 is direct and skin contact, and the protruding roughness that can increase reduces and wears the travelling comfort, so this statement's strengthening rib arch is located the earcap inner wall.

In addition, the shapes of the first supporting protrusions 230 include, but are not limited to, patterns of a truncated cone, a trapezoid, a triangle, a rectangle, a diamond, an ellipse, etc. with slowly changing heights, the first supporting protrusions are arranged symmetrically, the number of the first supporting protrusions can be 3-50, the supporting effect is too poor when the number of the first supporting protrusions is too small, and the arrangement is more compact due to the fact that the sizes of the reinforcing ribs need to be reduced when the number of the first supporting protrusions is too large, so that the manufacturability of the reinforcing structure is reduced.

Alternatively, referring to fig. 9 and 10 together, fig. 9 is a schematic structural diagram of a further embodiment of the earphone cap of the present application, fig. 10 is a schematic structural diagram of another perspective of the earphone cap of the embodiment of fig. 9, and the earphone cap 200 of the present embodiment also includes an inner ear cap 210 and an outer ear cap 220 which are integrally formed; the outer ear cap 220 is connected to the periphery of the first end of the inner ear cap 210, and extends toward the second end of the inner ear cap 210, the second end of the inner ear cap 210 is connected to the sound outlet 1111 of the casing 100, and the earphone cap 200 is made of a flexible battery material.

Wherein, the inside wall of outer ear cap 220 is equipped with a plurality of first support protrusions 230, and a plurality of first support protrusions 230 can be along the even symmetry setting of inside wall border ring circumference of outer ear cap 220. For the material and the detailed structural features of the first supporting protrusion 230, refer to the related description of the previous embodiments, and are not repeated here. Unlike the previous embodiments, the inner ear cap 210 in this embodiment is provided with a plurality of second supporting protrusions 240 near the sidewall of the outer ear cap 220. In the earphone cap structure of this embodiment, similar reinforcing structures can be made on the inner ear cap 210 at the same time, so that when the outer ear cap 220 deforms in the ear canal, the first supporting protrusion 230 and the second supporting protrusion 240 are dislocated and interfere with each other, the tuning hole 112 is kept in a non-blocking state, the spatial dimension of the sound insulation cavity 202 is kept, and the acoustic effect is further ensured.

Alternatively, the structure of the second support protrusion 240 may be an integral structure with the inner ear cap 210. It should be noted that the terms "first", "second" and "third" in the embodiments of the present application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
