Description

[Technical Field]

[0001] The present invention relates to the field of wearable devices, and is particularly directed to an earpiece adapted for earphones. [Background technology]

[0002] The earpiece is a soft rubber-based member attached to the sound outlet of the earphone body in the earphone, which can form a seal to reduce interference from external noise and provide better sound insulation, while also improving the firmness of the earphone when worn, providing a flexible wearing experience and reducing the tightness and discomfort felt when wearing the earphone for a long period of time.

[0003] However, because conventional earpieces are made of soft rubber, there are areas that are acoustically undesirable for the sound emitted from the speaker in the earphone body. This is because the earpiece is supported by a soft material such as silicone rubber, which makes it difficult for it to resonate with the frequency of the sound emitted from the speaker, making it difficult for clear sound to be transmitted to the ear. Summary of the Invention [Problem to be solved by the invention]

[0004] Based on this, there is a need to provide an earpiece and an earphone having an earpiece that improves the acoustic effect in response to the problems of the prior art. [Means for solving the problem]

[0017] As shown in Figure 1, an earphone 100 according to one embodiment of the present invention includes an earphone body 90 and an earpiece 10 attached to the earphone body 90. A speaker is attached inside the earphone body 90, and sound is emitted to the outside through a sound outlet (not shown). The earpiece 10 is attached to the sound outlet of the earphone body 90, and when worn by a user, a portion of the earpiece 10 is pressed into the ear canal, improving the firmness of the earphone.

[0018] 2 to 9, the earpiece 10 includes an earpiece body 20 and a metal ring 30 attached inside the earpiece body 20. The earpiece body 20 is made of a soft rubber material. In this embodiment, the earpiece body 20 is integrally injection molded from soft silica gel.

[0019] 4 and 5, the earpiece body 20 includes a housing 21 and an inner tube 22 connected to the housing 21. The housing 21 is installed as a bowl-shaped enclosure with both ends open. Specifically, the housing 21 includes a front end 215 and a rear end 216, and the diameter of the front end 215 is smaller than the diameter of the rear end 216. That is, the housing 21 gradually increases in diameter from the front end 215 to the rear end 216. An annular pattern 210 (shown in FIG. 2) is provided on the outer surface of the housing 21, thereby improving the breathability of the earpiece 10.

[0020] The inner cylinder 22 has a cylindrical shape and includes a connecting end 225 and an extending end 226 connected to the front end 215 of the housing 21. The outer diameter of the inner cylinder 22 is approximately the same, i.e., the connecting end 225 and the extending end 226 are approximately the same. The inner cylinder 22 is injection molded integrally with the housing 21. The exterior of the connecting end 225 is integrally molded with the interior of the front end 215, and the extending end 226 is located within the housing 21, with the outer wall of the extending end 226 spaced apart from the inner wall of the rear end 216 of the housing 21. Because the longitudinal length of the inner cylinder 22 is shorter than the longitudinal length of the housing 21, the rear end 216 extends beyond the extending end 226 in the longitudinal direction, i.e., the extending end 226 is located inward of the rear end 216. An accommodating passage 220 is provided in the center of the inner tube 22, and a through-hole 227 is provided in the extended end 226. The diameter of the through-hole 227 is smaller than the diameter of the accommodating passage 220, thereby forming a step 228 on the inner wall at the connection point between the extended end 226 and the center of the inner tube 22. This step 228, combined with the elasticity of the soft rubber of the inner tube 22 itself, is used to lock the convex ring on the sound outlet, thereby achieving a strong connection between the earpiece 10 and the earphone body 90.

[0021] The inner wall of the connecting end 225 of the inner tube 22 is provided with a plurality of spaced annular grooves 2250, which allow the metal ring 30 to be fitted and secured. In this embodiment, the metal ring 30 and the earpiece body 20 are integrally injection molded, specifically, by placing the metal ring 30 in a mold, injecting molten silica gel into it, and then cooling it.

[0022] 6 and 7, the metal ring 30 is made of a metal material. In this embodiment, the metal ring 30 is made of a stainless steel material. The metal ring 30 is attached to the inside of the connecting end 225 of the inner tube 22 and is used to collect sound emitted from the sound outlet of the earphone body 90 and then transmit it to the user's ear. Compared to the all-silica gel earpieces of the prior art, the earpiece 10 of the present invention adds a metal ring 30 at the sound outlet, which can significantly improve sound quality through resonance.

[0023] 8 and 9, the outer circumferential surface of the metal ring 30 has a plurality of annular protrusions 39 spaced apart, which fit into the annular groove 2250 of the inner tube 22. The metal ring 30 is hollow and has a sound-passing cavity 38 extending vertically therethrough. The sound-passing cavity 38 includes a sound-input segment 31, a sound-collecting segment 32, a middle segment 33, and a sound-output segment 34, which extend in this order from the extending end 226 toward the connecting end 225. The sound-input segment 31 and the middle segment 33 are both cylindrical, and the diameter of the middle segment 33 is smaller than the diameter of the sound-input segment 31. The sound pickup segment 32 contracts in an inverted cone shape from the sound input segment 31 toward the middle segment 33, and the sound pickup segment corresponding to the inner wall of the metal ring 30 is a first annular arch-shaped protrusion 320 with increasing vertical diameter from the sound input segment 31 to the middle segment 33. Accordingly, the sound output segment 34 expands outward from the middle segment 33 in a trumpet shape, and the sound output segment 34 corresponding to the inner wall of the metal ring 30 is a second annular arch-shaped protrusion 340 with decreasing vertical diameter from the middle segment 33. In other words, the sound input segment 31 and the sound pickup segment 32 collect and enhance the sound transmitted from the sound output port, and the middle segment 33 resonates the sound and finally amplifies it into the user's ear through the trumpet-shaped sound output segment 34, greatly enhancing the sound quality.
