Description

Technical Field

[0001] The present invention relates to the field of ear-insert type earphones, and particularly to custom earphones.

Background Art

[0002] Ear-insert type earphones usually incorporate dynamic speakers, and the outside of the speaker is a housing made of plastic or metal, combined with earplugs of different sizes. The initial purpose of such earphone designs was to achieve higher comfort and sealing. However, as the number of people using ear-insert type earphones increases, it has been found that even with earplugs of various sizes, they do not fit well with the size of each individual's ear canal, resulting in a sense of swelling and pain in the ear canal after long-term wearing. Since the earplug does not adhere well to the ear canal, the sound insulation effect is not very significant.

[0003] Therefore, in the prior art, in order to accommodate users with different ear canal sizes, earphones are manufactured using a customized method. For example, the custom wireless earphones disclosed in publication number CN11430394A include a custom housing and a panel assembly provided within the custom housing, and the custom housing is customized to accommodate users with different ear canal sizes. However, since the custom housing completely covers the panel assembly, it has led to a significant increase in cost.

The basic principles defined in the following description can be applied to other embodiments, variations, improvements, equivalent forms, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0022] As shown in FIGS. 1 and 2, the custom earphone A customizable in-ear insertion unit 100, comprising an opposing in-ear insertion inner end face 110 and an in-ear insertion outer end face 120, wherein the in-ear insertion outer end face 120 is adapted to the outer ear, the in-ear insertion unit 100, and A sound-emitting module 200 comprising opposing sound-emitting inner end faces 210 and sound-emitting outer end faces 220, wherein the sound-emitting inner end face 210 and the in-ear insertion inner end face 110 are joined, the sound-emitting module 200, and A sealing structure provided between the in-ear insertion inner end face 210 and the sound-emitting inner end face 110.

[0023] Compared with the use of silicon ear muffs and low-rebound material ear muffs in the prior art, silicon ear muffs may have a sense of swelling when worn for a long time, which may cause fatigue to the ears. Also, the average service life of low-rebound materials is only about 2 to 3 months, and the price is also high. The in-ear insertion outer end face 120 of the in-ear insertion unit 100 is a customizable type adapted to the outer ear, and has an auricle customization part 121 adapted to the auricle and an external auditory canal customization part 122 adapted to the external auditory canal. Thereby, it is adapted to the user's outer ear, bringing advantages such as improving comfort and service life and avoiding a decrease in sound insulation. The sound-emitting module 200 is a conventional component, and a panel assembly may be provided inside it. When the in-ear insertion unit 100 and the sound-emitting module 200 are joined, communication is realized. Only the in-ear insertion unit 100 is a customizable type. Compared with the method of customizing the entire earphone, it effectively reduces costs and avoids prolonging the production time. A sealing structure is provided between the in-ear insertion inner end face 210 and the sound-emitting inner end face 110 to ensure sealing and prevent sound from leaking out.

[0024] As shown in FIGS. 1 and 2, the in-ear insertion unit 100 includes an opposing in-ear insertion inner end face 110 and an in-ear insertion outer end face 120, and an in-ear insertion side face 130 connected between the in-ear insertion inner end face 110 and the in-ear insertion outer end face 120. The sound generating module 200 includes an opposing sound generating inner end face 210 and a sound generating outer end face 220, and a sound generating side face 230 connected between the sound generating inner end face 210 and the sound generating outer end face 220.

[0025] The in-ear insertion inner end face 110, and the sound generating inner end face 210 and the sound generating outer end face 220 are substantially flat, and the in-ear insertion side face 130 and the sound generating side face 230 are uneven surfaces. Since only the in-ear insertion outer end face 120 is adapted to the user's outer ear, only the shapes of the in-ear insertion outer end face 120 and the in-ear insertion side face 130 can be changed and customized according to users with different outer ear sizes, further reducing costs and shortening the customization time.

[0026] As shown in FIG. 1, the in-ear insertion unit 100 has an in-ear insertion recess 140, and the in-ear insertion inner end face 110 surrounds the outer periphery of the in-ear insertion recess 140. The sound generating module 200 has a sound generating protrusion 240, and the sound generating inner end face 210 surrounds the outer periphery of the sound generating protrusion 240. When the in-ear insertion inner end face 110 is joined to the sound generating inner end face 210, the sound generating protrusion 240 is fitted into the in-ear insertion recess 140.

The sound emitting protrusion 240 forms the sound emitting sound guiding tube 250 in a convex shape. When the inner end face 110 of the ear insertion and the inner end face 210 of the sound emitting part are joined, the sound emitting sound guiding tube 250 is fitted inside the ear insertion sound guiding tube 150, and the sound emitting sound guiding tube 250 and the ear insertion sound guiding tube 150 communicate with each other.

[0031] When the sound emitting sound guiding tube 250 and the ear insertion sound guiding tube 150 communicate with each other, communication between the ear insertion unit 100 and the sound emitting module 200 is realized and used for normal use. The sound emitting sound guiding tube 250 is fitted inside the ear insertion sound guiding tube 150 to further improve the sealing performance. The ear insertion sound guiding tube 150 is provided only on the bottom surface of the first side recess 141. The depth of the second side recess 142 is smaller than the depth of the first side recess 141, the weight is reduced, and the cost is reduced. The sound emitting sound guiding tube 250 has three tubes, which are respectively a movable coil sound guiding tube, a movable iron sound guiding tube, and a movable coil exhaust tube, and may be changed according to the configuration of different speakers.

On the sound-emitting inner end face 210, a first positioning member 261 on the sound-emitting side and a second positioning member 262 on the sound-emitting side are provided. The first positioning member 261 on the sound-emitting side and the first positioning member 161 on the ear-insertion side are positioned and connected, and the second positioning member 262 on the sound-emitting side and the second positioning member 162 on the ear-insertion side are connected.

[0033] By providing the above-described positioning members, the assembly accuracy between the ear-insertion unit 100 and the sound-emitting module 200 is ensured, and the assembly becomes easier.

[0034] Preferably, the first positioning member 161 on the ear-insertion side is a female type, the first positioning member 261 on the sound-emitting side is a male type, the second positioning member 162 on the ear-insertion side is a male type, and the second positioning member 262 on the sound-emitting side is a female type. The stability of the connection between the two is further improved.

[0035] As shown in Fig. 1, the first positioning member 161 on the ear-insertion side and the second positioning member 162 on the ear-insertion side are respectively located on the side portions away from the ear-insertion sound guide tube 150, and the first positioning member 261 on the sound-emitting side and the second positioning member 262 on the sound-emitting side are respectively located on the side portions away from the sound-emitting sound guide tube 250. The upper sides of the ear-insertion unit 100 and the sound-emitting module 200 are connected via the sound-emitting sound guide tube 250 and the ear-insertion sound guide tube 150, and the lower sides are connected via the positioning members, and the connection positions are shifted and arranged, which can be seen that the stability of the connection is improved.

[0036] Referring to Fig. 1, the sealing structure includes a sealing ring or an adhesive, which further improves the sealing performance and prevents the sound from leaking out.

[0037] When assembling the custom earphone, a sealing structure is provided on the inner end face 210 of the sound-emitting part or the inner end face 110 of the ear-inserting part. Then, the sound-emitting sound guide tube 250 and the ear-inserting sound guide tube 150 are aligned, and the positioning member is aligned. After that, the inner end face 210 of the sound-emitting part or the inner end face 110 of the ear-inserting part is joined to complete the assembly. At this time, the sealing structure is located between the inner end face 210 of the sound-emitting part and the inner end face 110 of the ear-inserting part. The custom earphone can be either wired or wireless and is suitable for ear-insert type earphones.

[0038] To summarize the above, the ear-inserting unit 100 is customizable. Therefore, it can fit the user's outer ear, bringing advantages such as improving comfort and service life and avoiding a decrease in sound insulation. Furthermore, only the ear-inserting unit 100 is customizable. Compared with the method of customizing the whole, it effectively reduces costs and avoids prolonging the production time. A sealing structure is provided between the inner end face 210 of the ear-inserting part and the inner end face 110 of the sound-emitting part to ensure sealing and prevent sound from leaking out.
