The utility model provides an ear cap 100.

In the embodiment of the present invention, as shown in fig. 1 and 2, the ear cap 100 includes: a housing 10, said housing 10 being adapted to fit an ear canal; the protrusions 20 are protruded on the inner wall surface of the housing 10, the number of the protrusions 20 is plural, and the plural protrusions 20 are distributed along the inner wall surface of the housing 10.

The housing 10 is in the shape of a cover with two open ends, and the cross section thereof may be circular or elliptical, which is not limited herein. One end of the housing 10 is covered on the shell of the earphone 200, and the other end is matched with the ear hole, so that the sound outlet of the earphone 200 can be fixed towards the ear hole. The radial dimension of the openings at the two ends of the housing 10 may be uniform, or may be tapered from the end far away from the ear hole to the end near the ear hole, which is not limited herein. The shell 10 may be made of a flexible or resilient material that is squeezed into secure engagement with the ear canal during insertion into the ear canal. The shape and size of the protrusion 20 are not limited, and only need to be protruded from the inner wall surface of the outer cover 10. The distribution density of the protrusions 20 is not limited, and only the distribution in the circumferential direction and the axial direction of the outer cover 10 is satisfied. When the earcap 100 is assembled to the shell of the earphone 200, the end of the protrusion 20 faces the shell of the earphone 200, and the protrusion 20 may abut against the shell of the earphone 200 or form a gap with the shell of the earphone 200, which is not limited herein. When the housing 10 is fitted into the ear hole, the protrusion 20 can abut against the shell of the earphone 200 under the pressure of the ear hole, thereby integrally clamping the earphone 200 at the ear hole. Since the earphone 200 also applies a reaction force to the ear hole through the protrusion 20, the housing 10 can be closely fitted to the ear hole to improve the sealing performance of the wearing of the earphone 200. Because the number of the bulges 20 is a plurality of and is distributed along the inner wall surface of the outer cover 10, the sealing performance of the matching of each part of the outer cover 10 and the ear hole can be comprehensively improved, and the pressure intensity of a single part to the ear hole can be reduced, so that the wearing comfort is improved. The distribution of the protrusions 20 in the earcap 100 requires less raw materials and is less costly than filling with memory material or latex, and thus the overall production cost of the earphone 200 can be effectively reduced.

In an embodiment, the protrusion 20 is provided as a resilient protrusion 20. The protrusion 20 is made of an elastic material or an elastic element, and may be rubber, sponge, air bag or metal spring, which is not limited herein, and only needs to have elasticity. Elastic bulge 20 can take place elastic deformation when being extruded to the internal face of earcap 100 produces elasticity reaction force, and this elasticity reaction force further transmits to people's ear again, thereby not only makes earcap 100 closely cooperate with the earhole, can reduce the actual pressure to the earhole again, in order to improve and wear the comfort level, improves user experience. Specifically, the protrusion 20 is a silica gel protrusion, and the protrusion 20 is made of a silica gel material, which has sufficient elasticity, and the raw materials are more easily obtained and easier to process, so that the production cost of the earcap 100 can be further reduced. The silica gel has more stable chemical property, and is more corrosion-resistant and aging-resistant; and the silicone rubber has higher toughness and is not easily damaged even if being frequently squeezed, so that the service life of the ear cap 100 can be prolonged. In addition, the silica gel has good electrical insulation performance, and can prevent the earphone 200 from leaking electricity towards the ear of a person, so that the safety performance of the earphone 200 is improved. In practical applications, the cover 10 may also be made of silicone, so that the cover 10 also has elasticity, electrical insulation, corrosion resistance, aging resistance, etc., thereby simultaneously prolonging the service life of the cover 10 and the protrusions 20. The protrusion 20 and the housing 10 can be integrally formed to be integrally injection-molded by the same mold, so that the connection strength between the protrusion 20 and the housing 10 can be improved, and the production difficulty and the production cost of the ear cap 100 can be reduced.

In one embodiment, as shown in fig. 1, the protrusion 20 is disposed in a cylindrical shape, which is easier to machine than a square column shape, so as to reduce the difficulty of manufacturing the ear cap 100. The cylinder is better deformed when being extruded, and elastic acting force is easier to generate, so that the ear cap 100 is easier to be matched with the ear hole, and a user can wear the ear cap conveniently. Specifically, the peripheral edge of the end of the protrusion 20 may be rounded to avoid scratching the shell of the earphone 200, thereby improving the protection effect of the earphone 200. In practical applications, the end of the protrusion 20 may be spherically disposed, so as to be more easily abutted against the shell of the earphone 200 and more easily deformed by a force.

In one embodiment, the width of the protrusion 20 is not less than 0.5mm and not more than 2 mm; in connection with the above-described embodiment in which the protrusion 20 is cylindrical, the width of the protrusion 20 is the radial dimension of the protrusion 20. The width of the bulge 20 can affect the volume and the pressure on the ear hole, and if the width of the bulge 20 is less than 0.5mm, the sectional area is too small, and the pressure on the ear hole is too large; if the width of the protrusion 20 is greater than 2mm, the overall size of the protrusion 20 is too large, which is not conducive to deformation, and the earcap 100 cannot be fitted with the earhole; therefore, setting the width of the protrusion 20 to 0.5mm to 2mm can improve both the wearing comfort of the earcap 100 and the wearing stability of the earcap 100.

In one embodiment, the distance between two adjacent protrusions 20 is not less than 0.5mm and not more than 3 mm. The distance between two adjacent protrusions 20 can affect the matching effect of the earcap 100 and the earhole, and if the distance between two adjacent protrusions 20 is less than 0.5mm, in the process that the earcap 100 enters the earhole, because the internal space of the earcap 100 becomes smaller, the adjacent protrusions 20 can be mutually extruded, so that the earcap 100 cannot be normally deformed, and cannot be effectively installed in the earhole; if the distance between two adjacent protrusions 20 is greater than 3mm, the part of the inner wall surface of the outer cover 10 between the two protrusions 20 cannot be effectively close to the ear hole, so that the ear cap 100 is not tightly matched with the ear hole, and the wearing tightness of the ear cap 100 is reduced; therefore, the distance between two adjacent protrusions 20 is set to be 0.5mm to 3mm, which can ensure that the ear cap 100 can be normally installed in the ear hole and can improve the wearing tightness of the ear cap 100.

In one embodiment, as shown in fig. 1, the earcap 100 further comprises an inner cylinder 30 disposed inside the outer cover 10, the protrusion 20 is located between the outer cover 10 and the inner cylinder 30, and the inner cylinder 30 is configured to cooperate with a sound outlet of the shell of the earphone 200. One end of the inner cylinder 30 is connected to the opening edge of the outer cover 10 near the ear hole, and the other end is used for being inserted into the sound outlet of the shell of the earphone 200, so that the ear cap 100 is firmly matched with the shell of the earphone 200; the inner tube 30 is also used to communicate the sound outlet with the opening of the outer cover 10, so as to clearly and completely transmit the sound played by the earphone 200 to the ear hole. The inner cylinder 30 can be integrally injection molded with the outer cover 10 to improve the connection strength and reduce the processing difficulty. Specifically, the outer cover 10 is in a cone shape, and openings are formed at two ends of the outer cover 10, so that the earcap 100 can smoothly enter the earhole, and the process of wearing the earphone by the user is simpler and more convenient

As shown in fig. 2, the present invention further provides an earphone 200, wherein the earphone 200 includes a housing 40 and an ear cap 100, the specific structure of the ear cap 100 refers to the above embodiments, and since the earphone 200 adopts all the technical solutions of all the above embodiments, all the beneficial effects brought by the technical solutions of the above embodiments are at least achieved, and are not repeated herein. Wherein, the outer cover 10 of the ear cap 100 is sleeved on the sound outlet of the casing 40.

Specifically, as shown in fig. 2, a gap is provided between the protrusion 20 of the ear cap 100 and the housing 40. When the ear cap 100 is installed in the ear hole, the protrusion 20 is pressed to abut against the housing 40 and then starts to deform, so that the ear cap 100 and the ear hole have a sufficient matching area, and then the protrusion 20 provides a reaction force to press and fix, thereby enabling the wearing process of the earphone 200 to be simpler and more convenient. In practical application, the distance between the protrusion 20 and the housing 40 may be set to 0.5mm to 3mm, so as to ensure that the housing 10 and the ear hole have a sufficient fitting area, and also ensure that the housing 40 can press and fix the housing 10 to the ear hole through the protrusion 20, thereby improving the wearing stability and the sealing performance of the earphone 200.

The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
