Description

Technical Field

[0001] The utility model belongs to the technical field of earphone accessories, and particularly relates to a silicone ear cap. Background Art

[0002] With the increasing popularity of electronic devices, headphones have become an indispensable auxiliary tool in people's daily life and work. Among the current headphone categories, in-ear headphones have a higher penetration rate. They require an ear cap to be installed on the outside of the headphone shell, and the sound enters the user's ear cavity through the ear cap from the sound outlet of the headphone. The existing ear cap part only uses one layer of material to increase the contact comfort between the headphone and the ear, and the comfort level is not high; some ear caps with multiple layers of compression to improve comfort do not have exhaust and sewage discharge functions, and are often unclean when inserted into the ear. Utility Model Content

[0003] The utility model provides a silicone ear cap to solve the above technical problems.

[0004] The solution adopted by the utility model to achieve its technical effect is:

[0005] A silicone ear cap, comprising a cap post and a cap sleeve; the cap post comprises a connecting part and a compression part; a connecting cavity is arranged in the connecting part; the compression part is arranged at the top of the connecting part; two compression cavities are arranged at intervals on the inner side of the compression part; the two compression cavities are communicated with the connecting cavity; a compression groove is arranged on the outer side of the compression part; the compression groove is located on the outer side of the compression part where the spacing cavity between the two compression cavities is located; a guide exhaust hole is arranged on the compression part between the compression groove and the upper side of the spacing cavity; the cap sleeve is arranged on the top of the compression part, and the cap sleeve is sleeved on the connecting part and the outer side of the compression part; the cap opening at the top of the cap sleeve is communicated with the two compression cavities.

[0006] Preferably, a cavity wall of the connecting cavity is provided with a connecting slot.

[0007] Preferably, a spacing baffle is provided in the spacing cavity; a sound-transmitting hole is provided on the spacing baffle; and the inner opening of the air guide and exhaust hole is located above the spacing baffle.

[0008] Preferably, the inner wall diameters of the two compression chambers are larger than the inner wall diameters of the connecting chamber and the inner wall diameters of the spacing cavity; the inner wall diameters of the spacing cavity are consistent with the inner wall diameters of the connecting chamber and the inner wall diameters of the cap opening.

[0009] Preferably, the inner wall diameters of the two compression chambers are larger than the inner wall diameters of the connecting chamber and the inner wall diameters of the spacing cavity; the inner wall diameter of the spacing cavity is smaller than the inner wall diameters of the connecting chamber and the inner wall diameters of the cap opening; the inner wall diameter of the connecting chamber is consistent with the inner wall diameter of the cap opening.

[0010] Preferably, a pre-turned groove is provided on the inner side of the cap sleeve close to the compression portion.

[0011] The beneficial effects of the utility model are as follows: a compression part is provided, and the compression part is composed of two compression chambers and a compression groove. When the silicone ear cap and the earphone are inserted into the ear, the two compression chambers and the compression groove are gradually elastically compressed and fitted with each other. The elastic force can not only effectively increase the degree of fixation of the earphone inserted into the ear, but also improve the comfort of the contact between the ear and the earphone. A diversion exhaust hole is provided, and the air compressed by the compression part can be discharged from the diversion exhaust hole. The silicone ear cap can be manually compressed and exhausted before being inserted into the ear, thereby improving the safety for the human body; at the same time, the diversion exhaust hole also facilitates the earwax flowing into the inner wall of the compression part to flow out from the diversion exhaust hole, thereby improving the cleanliness after long-term use.

DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model. It should be noted that when an element is referred to as "fixed on" or "set on" another element, it can be directly on the other element or there may be a centering element at the same time. When an element is referred to as "connected to" another element, it can be directly connected to the other element or there may be a centering element at the same time. When an element is referred to as being "fixedly connected to" another element, it can be a common fixed connection method such as welding, bolting or gluing.

[0016] Please refer to Figure 1In a preferred embodiment of the utility model, a silicone ear cap is disclosed, comprising a cap column and a cap sleeve 1; the cap column comprises a connecting portion 2 and a compression portion 3; a connecting cavity 4 is arranged in the connecting portion 2; the compression portion 3 is arranged at the top of the connecting portion 2; two compression cavities 5 are arranged at intervals on the inner side of the compression portion 3; the two compression cavities 5 are communicated with the connecting cavity 4; a compression groove 6 is arranged on the outer side of the compression portion 3; the compression groove 6 is located on the outer side of the compression portion 3 where the spacing cavity 7 between the two compression cavities 5 is located; a guide exhaust hole 8 is arranged on the compression portion 3 at a position between the compression groove 6 and the spacing cavity 7; the cap sleeve 1 is arranged on the top of the compression portion 3, and the cap sleeve 1 is sleeved on the connecting portion 2 and the outer side of the compression portion 3; the cap opening at the top of the cap sleeve 1 is communicated with the two compression cavities 5.

[0017] Specifically, a connection slot 9 is provided on the cavity wall of the connection cavity 4 .

[0018] Specifically, a spacing baffle 11 is disposed in the spacing cavity 7 , a sound-transmitting hole 12 is disposed on the spacing baffle 11 , and an inner opening of the air guide and exhaust hole 8 is located above the spacing baffle 11 .

[0019] Please refer to Figure 1 In one preferred embodiment of the present invention, the inner diameters of the two compression chambers 5 are larger than the inner diameters of the connecting chamber 4 and the inner diameters of the spacing chamber 7; the inner diameter of the spacing chamber 7 is consistent with the inner diameters of the connecting chamber 4 and the inner diameters of the cap opening. When the compression portion 3 is compressed, the overall diameter of the internal space of the cap column is substantially consistent, that is, the diameter of the sound transmission channel of the earphone is substantially consistent, thereby ensuring that the sound is effectively transmitted to the ear without loss.

[0020] Please refer to Figure 2 In another preferred embodiment of the utility model, the inner wall diameter of the two compression chambers 5 is larger than the inner wall diameter of the connecting chamber 4 and the inner wall diameter of the spacing cavity 7; the inner wall diameter of the spacing cavity 7 is smaller than the inner wall diameter of the connecting chamber 4 and the inner wall diameter of the cap opening; the inner wall diameter of the connecting chamber 4 is consistent with the inner wall diameter of the cap opening.
