Description

An adaptive rebound earphone and earphone module Technical Field

[0001] This application relates to the field of headphone technology, and in particular to an adaptive rebound headphone and headphone module. Background Technology

[0002] In today's society, headphones have become an indispensable electronic product in people's daily lives. Among them, headphones are increasingly favored by users due to their unique wearing method and stylish appearance. The most distinctive feature of headphones is their wearing method; the headphone body is worn by fitting snugly against the contours of the earphone through an air bladder.

[0003] The problem with the aforementioned headphones is that the airbag cannot adapt to the dynamic changes in the ear's contour and cannot adjust its shape in time according to these changes. This results in poor stability and fit between the airbag and the ear's contour, thus reducing the headphones' wearing comfort and stability. Summary of the Invention

[0004] To address the aforementioned issues, this application provides an adaptive rebound earphone and earphone module that enables the airbag to rapidly adapt and rebound, thereby ensuring that the airbag can stably conform to the ear contour in various usage scenarios, thus improving the wearing comfort and stability of the earphone.

[0005] In a first aspect, this application provides an adaptive rebound earphone, which includes an earphone body, an airbag, and an adjustment component. The airbag is connected to the earphone body, and the side of the airbag facing away from the earphone body is used to fit the contour of the ear. An airbag cavity is formed on the side of the airbag near the earphone body. The adjustment component includes a main exhaust channel, which is opened on the side of the airbag near the earphone body. The first end of the main exhaust channel is located inside the airbag cavity, and the second end of the main exhaust channel communicates with the outside to connect the airbag cavity with the outside.

[0006] The adaptive rebound earphone provided in this application features a main exhaust channel on the side of the airbag closest to the earphone body. The first end of the main exhaust channel is located inside the airbag cavity, and the second end connects to the outside. When the earphone is worn on the ear contour, and the side of the airbag facing away from the earphone body fits against the ear contour, if the ear contour compresses the airbag due to movement, the gas inside the airbag cavity can be quickly expelled through the main exhaust channel, reducing the internal pressure of the airbag cavity. This allows the airbag to quickly adapt to the deformation of the ear contour. When the pressure on the ear contour is released, external air can enter the airbag cavity through the main exhaust channel in the opposite direction, increasing the internal pressure of the airbag cavity. This allows the airbag to quickly return to its initial state, maintaining a stable fit with the ear. This enables the airbag to achieve rapid adaptive rebound, and the airbag can adjust in real time according to the dynamic changes in the ear contour, ensuring a stable fit in various usage scenarios, thereby improving the wearing comfort and stability of the earphone. Compared to related technologies, where the airbag cannot adapt to the dynamic changes in the ear contour and cannot adjust its shape in time according to these changes, resulting in poor stability and fit between the airbag and the ear contour, thus reducing the wearing comfort and stability of the headphones, this application addresses the technical problem of opening a main exhaust groove on the side of the airbag near the headphone body. This allows the headphone to enable the airbag to quickly adapt and rebound, thus ensuring a stable fit between the airbag and the ear contour in various usage scenarios, thereby improving the wearing comfort and stability of the headphones.

[0007] In one possible implementation provided in this application, the first end of the main exhaust channel is located at the center of the airbag cavity.

[0008] In one possible implementation provided in this application, the projection of the airbag along the connection direction between the airbag and the headphone body is a closed shape, and there are multiple main exhaust channels. The multiple main exhaust channels are evenly distributed along the circumference of the outer contour of the closed shape on the side of the airbag close to the headphone body.

[0009] In one possible implementation provided in this application, the adjustment component further includes a secondary exhaust channel, which is located on the side of the airbag near the main body. The first end of the secondary exhaust channel is connected to the main exhaust channel, and the second end of the secondary exhaust channel is connected to the outside.

[0010] In one possible implementation provided in this application, the projection of the airbag along the connection direction between the airbag and the headphone body is a closed shape. There is one main exhaust groove and multiple secondary exhaust grooves. The first ends of the multiple secondary exhaust grooves are all connected to the main exhaust groove, and the second ends of the multiple secondary exhaust grooves are all connected to the outside. The multiple secondary exhaust grooves are evenly distributed along the circumference of the outer contour of the closed shape on the side of the airbag close to the headphone body. The main exhaust groove is opened between two adjacent secondary exhaust grooves.

[0011] In one possible implementation provided in this application, the circumferential dimensions of the plurality of secondary exhaust channels along the outer contour of the closed shape are all smaller than the circumferential dimensions of the main exhaust channel along the outer contour of the closed shape.

[0012] In one possible implementation provided in this application, the earphone body includes a first part and a second part. The first part has a protrusion extending from the side of the second part near the airbag, and a snap-fit ​​groove is formed on the protrusion. A snap-fit ​​protrusion extends from the side of the airbag near the earphone body along the direction of the airbag cavity. The snap-fit ​​protrusion extends into the snap-fit ​​groove to snap the earphone body and the airbag together. When the earphone body and the airbag are snapped together, at least the side of the snap-fit ​​protrusion away from the airbag cavity and the second part are provided with a communication channel along the connection direction between the earphone body and the airbag. The secondary exhaust groove and the main exhaust groove are connected through the communication channel.

[0013] In one possible implementation provided in this application, the boss or snap-fit ​​protrusion is made of an elastic material.

[0014] In one possible implementation provided in this application, the side of the airbag away from the airbag cavity is recessed along the side away from the headphone body to form an adhesive dispensing part. The adhesive dispensing part is used for dispensing adhesive. When the snap-fit ​​protrusion extends into the snap-fit ​​groove, the headphone body and the airbag are bonded together by the adhesive dispensing part.

[0015] Secondly, this application provides an adaptive rebound headphone module, which includes a headphone case and adaptive rebound headphones provided in any of the first aspects, wherein the adaptive rebound headphones are housed in the headphone case.

[0016] The adaptive rebound earphone module provided in this application, since it includes the adaptive rebound earphone provided in any of the first aspects, has the same technical effect. That is, it enables the airbag to achieve rapid adaptive rebound, so that the airbag can stably fit the ear contour in various usage scenarios, thereby improving the wearing comfort and stability of the earphone.

[0034] Referring to Figures 1 and 2, this application embodiment provides an adaptive rebound earphone, which includes an earphone body 1, an airbag 2, and an adjustment component 3. The airbag 2 is connected to the earphone body 1, and the side of the airbag 2 facing away from the earphone body 1 is used to fit the contour of the ear. An airbag cavity is formed on the side of the airbag 2 near the earphone body 1. The adjustment component 3 includes a main exhaust channel 31, which is opened on the side of the airbag 2 near the earphone body 1. The first end of the main exhaust channel 31 is located inside the airbag cavity, and the second end of the main exhaust channel 31 communicates with the outside to connect the airbag cavity with the outside.

[0035] In this embodiment, the adaptive rebound earphone can be an open-back earphone; it can also be a closed-back earphone; it can also be an ear-hook or clip-on earphone; it can also be a headphone; it can also be a true wireless stereo (TWS) earphone; it can also be an open wearable stereo (OWS) earphone; this embodiment does not limit the specific type of earphone. In one possible implementation provided in this embodiment, the adaptive rebound earphone is a clip-on earphone among open-back wireless earphones.

[0036] In this embodiment, the adaptive rebound earphone includes an earphone body 1 and an airbag 2. The earphone body 1 may include a front-ear component 11, a back-ear component 12, and a connecting component 13. The connecting component 13 is located between the front-ear component 11 and the back-ear component 12 to connect them into a single unit. The airbag 2 is disposed on at least one of the front-ear component 11 and the back-ear component 12. This embodiment does not limit the scope of the embodiment. In one possible implementation, the airbag 2 is disposed on the front-ear component 11. Furthermore, the front-ear component 11 may also contain an earphone speaker, and the back-ear component 12 may contain an earphone battery, an earphone magnet, and an earphone antenna. The connecting component 13 may also include an ear clip wire, and both ends of the connecting component 13 are respectively provided with hard adhesive to connect to the front-ear component 11 and the back-ear component 12.

[0037] In this embodiment, the adaptive rebound earphone includes an earphone body 1 and an airbag 2. Here, the airbag 2 can be made of silicone; of course, the airbag 2 can also be made of other materials, such as rubber, and this embodiment does not limit this. In one possible implementation provided by this embodiment, the airbag 2 is made of silicone, which has advantages such as fit and stability, thereby improving the user's wearing comfort.

[0038] In this embodiment, the airbag 2 is connected to the earphone body 1. The connection between the airbag 2 and the earphone body 1 can be non-removable, for example, by welding or bonding. Alternatively, the connection can be detachable, for example, by threading or snap-fitting. This embodiment does not limit the specific method used. In one possible implementation, the airbag 2 and earphone body 1 are fixed using a combination of adhesive application and snap-fitting, making the connection between the airbag 2 and the earphone body more secure and reliable. Adhesive application provides good bonding strength, while snap-fitting further enhances the stability of the connection from a mechanical perspective. The two work together to effectively prevent the airbag 2 from loosening or falling off during daily use, extending the lifespan of the adaptive rebound earphone.

[0039] In this embodiment, an air bladder cavity is formed on the side of the air bladder 2 near the headphone body 1. Here, the inner contour of the air bladder cavity can be a regular structure, for example, the inner contour of the air bladder cavity is a cylindrical structure; or for example, the inner contour of the air bladder cavity is an elliptical structure; of course, the inner contour of the air bladder cavity can also be an irregular shape; this embodiment does not limit this.

[0040] In this embodiment, the adjustment component 3 includes a main exhaust groove 31, which is located on the side of the airbag 2 near the headphone body 1. The first end of the main exhaust groove 31 is located inside the airbag cavity, and the second end of the main exhaust groove 31 is connected to the outside to connect the airbag cavity with the outside. Here, the first end of the main exhaust groove 31 can be located at the edge of the airbag cavity; the first end of the main exhaust groove 31 can also be located at the center of the airbag cavity. This embodiment does not limit the scope of this application.

[0041] The adaptive rebound headphones provided in this application embodiment have a main exhaust groove 31 on the side of the airbag 2 near the headphone body 1. At this time, the first end of the main exhaust groove 31 is located inside the airbag cavity, and the second end of the main exhaust groove 31 is connected to the outside, so that the airbag cavity is connected to the outside. When the headphones are worn on the ear contour, and the side of the airbag 2 away from the headphone body 1 fits against the ear contour, if the ear contour squeezes the airbag 2 due to movement, the gas in the airbag cavity can be quickly discharged through the main exhaust groove 31, reducing the internal pressure of the airbag cavity, so that the airbag 2 can quickly adapt to the deformation of the ear contour. If the pressure of the ear contour is released, external air can enter the airbag cavity in the opposite direction through the main exhaust groove 31, increasing the internal pressure of the airbag cavity, so that the airbag 2 can quickly return to the initial state and maintain a stable fit with the ear. This allows the airbag 2 to achieve rapid adaptive rebound. The airbag 2 can be adjusted in real time according to the dynamic changes of the ear contour, so that the airbag 2 can stably fit the ear contour in various usage scenarios, thereby improving the wearing comfort and stability of the headphones. Based on this, the adaptive rebound headphones provided in this application are innovative and practical, and can significantly improve the performance and user experience of headphone products. They have obvious advantages in terms of wearing comfort, stability and structural robustness, which helps to improve the market competitiveness of products and bring better economic benefits to enterprises.

[0042] Compared to related technologies, the airbag 2 cannot adapt to the dynamic changes of the ear contour and cannot adjust its shape in time according to the dynamic changes of the ear contour, resulting in poor stable fit between the airbag 2 and the ear contour, thus reducing the wearing comfort and stability of the headphones. In this embodiment, the main exhaust groove 31 is opened on the side of the airbag 2 near the headphone body 1, so that the headphones can enable the airbag 2 to quickly adapt and rebound, so that the airbag 2 can stably fit the ear contour in various usage scenarios, thereby improving the wearing comfort and stability of the headphones.

[0043] Referring to Figures 3 and 4, an embodiment of this application provides an adaptive rebound earphone, wherein the first end of the main exhaust groove 31 is located at the center of the airbag cavity.

[0044] In this embodiment, the first end of the main exhaust groove 31 is located at the center of the airbag cavity. For example, if the inner contour of the airbag cavity is a spherical structure, the first end of the main exhaust groove 31 can be located at the center of the sphere; or if the inner contour of the airbag cavity is a cube structure, the first end of the main exhaust groove 31 can be located at the center of the cube; or if the inner contour of the airbag cavity is an irregular structure, the first end of the main exhaust groove 31 can be located at the center of gravity of the irregular structure. This embodiment does not impose any limitations on these aspects.

[0045] The adaptive rebound earphone provided in this application embodiment, by positioning the first end of the main exhaust groove 31 at the center of the airbag cavity, facilitates the positioning of the first end of the main exhaust groove 31; on the other hand, during exhaust or intake, air is first introduced into the center of the airbag cavity, which is beneficial to the stable deformation of the airbag 2.

[0046] Referring to Figures 5, 6, 7 and 8, this embodiment of the application provides an adaptive rebound earphone. The projection of the airbag 2 along the connection direction between the airbag 2 and the earphone body 1 is a closed shape. There are multiple main exhaust grooves 31, which are evenly distributed circumferentially along the outer contour of the closed shape on the side of the airbag 2 close to the earphone body 1.

[0047] In this embodiment, the projection of the airbag 2 along the connection direction between the airbag 2 and the earphone body 1 is a closed shape. Here, the closed shape can be a regular shape, such as a circle or a square; of course, the closed shape can also be an irregular shape, and this embodiment does not limit this. In one possible implementation provided by this embodiment, the closed shape is a circle, and correspondingly, the circumferential direction of the outer contour of the closed shape should also be the circumferential direction of the circle.

[0048] In this embodiment, there are multiple main exhaust channels 31. These channels are evenly distributed along the circumference of the outer contour of the closed shape on the side of the airbag 2 near the earphone body 1. Alternatively, there may be two main exhaust channels 31, which are evenly distributed along the circumference of the outer contour of the closed shape at 180-degree intervals on the side of the airbag 2 near the earphone body 1. Of course, there may also be four main exhaust channels 31, which are evenly distributed along the circumference of the outer contour of the closed shape at 90-degree intervals on the side of the airbag 2 near the earphone body 1. This embodiment does not limit the scope of the application.

[0049] In this embodiment, the circumferential dimension of the main exhaust groove 31 along the outer contour of the closed shape can be 5 mm, 10 mm, or 15 mm; this embodiment does not impose any limitation on this. In one possible implementation provided by this embodiment, through precise calculation, it is possible to ensure that the gas in the airbag cavity can be quickly discharged when the pressure of the ear contour changes, while preventing excessive gas leakage that could cause the airbag 2 to rebound excessively. There is one main exhaust groove 31, and the circumferential dimension of the main exhaust groove 31 along the outer contour of the closed shape is greater than or equal to 5 mm and less than or equal to 10 mm, to meet the exhaust requirements under different usage scenarios.

[0050] The adaptive rebound headphones provided in this application embodiment are provided with multiple main exhaust channels 31, which are evenly distributed along the circumference of the outer contour of the closed shape on the side of the airbag 2 close to the headphone body 1, so as to accelerate the speed at which the gas in the airbag cavity is discharged to the outside through the main exhaust channels 31 and the speed at which the outside air enters the airbag cavity through the main exhaust channels 31.

[0051] Referring to Figures 5, 6, 7 and 8, this application embodiment provides an adaptive rebound earphone. The adjustment component 3 further includes a secondary exhaust groove 32, which is opened on the side of the airbag 2 near the main body. The first end of the secondary exhaust groove 32 is connected to the main exhaust groove 31, and the second end of the secondary exhaust groove 32 is connected to the outside.

[0052] In this embodiment, the first end of the auxiliary exhaust channel 32 is connected to the main exhaust channel 31. It should be noted that the first end of the auxiliary exhaust channel 32 is only connected to the main exhaust channel 31 and not to the airbag cavity. Furthermore, the first end of the auxiliary exhaust channel 32 is connected to a portion of the main exhaust channel 31 near its first end; the first end of the auxiliary exhaust channel 32 is connected to a portion of the main exhaust channel 31 near its second end; and the first end of the auxiliary exhaust channel 32 is connected to a portion of the main exhaust channel 31 located between its first and second ends. This embodiment does not limit the scope of this embodiment. Alternatively, the first end of the auxiliary exhaust channel 32 can be directly connected to the main exhaust channel 31, meaning the first end of the auxiliary exhaust channel 32 extends into the main exhaust channel 31. Of course, the first end of the auxiliary exhaust channel 32 can also be indirectly connected to the main exhaust channel 31. This embodiment does not limit the scope of this embodiment.

[0053] The adaptive rebound headphones provided in this application embodiment have a secondary exhaust groove 32, with the first end of the secondary exhaust groove 32 connected to the main exhaust groove 31 and the second end of the secondary exhaust groove 32 connected to the outside. When the headphones are worn on the ear contour, if the ear contour squeezes the airbag 2 due to movement, the gas in the airbag cavity is first quickly discharged through the main exhaust groove 31 to reduce the internal pressure of the airbag cavity, so that the airbag 2 can quickly adapt to the deformation of the ear contour. At the same time, the secondary exhaust groove 32 will also discharge some gas simultaneously, further accelerating the exhaust speed and realizing the rapid rebound of the airbag 2. Once the pressure on the ear contour is released, external air enters the airbag cavity in the opposite direction through the main exhaust channel 31 and the secondary exhaust channel 32, causing the airbag 2 to quickly return to its initial state and maintain a stable fit with the ear contour. Through the double-layer design of the main exhaust channel 31 and the secondary exhaust channel 32, the airbag 2 can quickly adapt to the dynamic changes of the ear contour and adjust its shape in a timely manner according to the movement of the ear contour, always maintaining a close fit with the ear contour. This effectively avoids the problem of sound leakage and sound quality degradation caused by changes in fit, improving wearing comfort and stability. Whether during sports, daily activities, or long-term wear, users can enjoy a more comfortable and stable wearing experience.

[0054] Referring to Figures 5, 6, 7, and 8, this embodiment of the application provides an adaptive rebound earphone. The projection of the airbag 2 along the connection direction between the airbag 2 and the earphone body 1 is a closed shape. There is one main exhaust groove 31 and multiple secondary exhaust grooves 32. The first ends of the multiple secondary exhaust grooves 32 are all connected to the main exhaust groove 31, and the second ends of the multiple secondary exhaust grooves 32 are all connected to the outside. The multiple secondary exhaust grooves 32 are evenly distributed along the circumference of the outer contour of the closed shape on the side of the airbag 2 close to the earphone body 1. The main exhaust groove 31 is opened between two adjacent secondary exhaust grooves 32.

[0055] For example, there is one main exhaust groove 31 and four secondary exhaust grooves 32. The four secondary exhaust grooves 32 are evenly distributed at 90-degree intervals along the circumference of the outer contour of the closed shape on the side of the airbag 2 near the headphone body 1. The main exhaust groove 31 is opened between two adjacent secondary exhaust grooves 32. It should be noted that the number and distribution of the secondary exhaust grooves 32 can be optimized according to the size and shape of the airbag 2.

[0056] The adaptive rebound headphones provided in this application embodiment, when the pressure changes of the ear contour are relatively complex, the secondary exhaust groove 32 assists the main exhaust groove 31 in exhausting, accelerating the exhaust speed, thereby realizing the rapid rebound of the airbag 2.

[0057] Referring to Figures 5, 6, 7, and 8, this embodiment of the application provides an adaptive rebound earphone, wherein the circumferential dimensions of the plurality of secondary exhaust slots 32 along the outer contour of the closed shape are all smaller than the circumferential dimensions of the main exhaust slot 31 along the outer contour of the closed shape.

[0058] For example, the circumferential dimension of the main exhaust groove 31 along the outer contour of the closed shape is greater than or equal to 5 mm and less than or equal to 10 mm, and correspondingly, the circumferential dimension of the plurality of auxiliary exhaust grooves 32 along the outer contour of the closed shape is less than 5 mm.

[0059] The adaptive rebound earphone provided in this application embodiment ensures that the circumferential dimensions of the multiple secondary exhaust channels 32 along the outer contour of the closed shape are all smaller than the circumferential dimensions of the main exhaust channel 31 along the outer contour of the closed shape. This prevents the airbag 2 from rebounding excessively due to excessive gas leakage while ensuring that the gas in the airbag cavity can be quickly discharged during the process of pressure change on the ear contour.

[0060] Referring to Figures 1, 2, 3, and 4, this application embodiment provides an adaptive rebound earphone. The earphone body 1 includes a first part 14 and a second part 15. The first part 14 has a protrusion 141 extending from the side of the second part 15 near the airbag 2. The protrusion 141 has a snap-fit ​​groove 1411. The airbag 2 has a snap-fit ​​protrusion 22 extending from the side of the earphone body 1 along the direction of the airbag cavity. The snap-fit ​​protrusion 22 extends into the snap-fit ​​groove 1411 to snap the earphone body 1 and the airbag 2. When the earphone body 1 and the airbag 2 are snapped together, at least the side of the snap-fit ​​protrusion 22 away from the airbag cavity and the second part 15 are provided with a communication channel 4 along the connection direction between the earphone body 1 and the airbag 2. The secondary exhaust groove 32 and the main exhaust groove 31 are connected through the communication channel 4.

[0061] In this embodiment, the earphone body 1 includes a first part 14 and a second part 15. Here, the second part 15 may surround the first part 14; the second part 15 may also be surrounded by the first part 14. This embodiment does not limit the scope of the application. In one possible implementation provided by this embodiment, the second part 15 may surround the first part 14.

[0062] In this embodiment, the first part 14 extends a protrusion 141 relative to the second part 15 along the side close to the airbag 2. Here, the protrusion 141 can have a certain elasticity and toughness, which facilitates the insertion of the snap-fit ​​protrusion 22 into the snap-fit ​​groove 1411 to snap the earphone body 1 and the airbag 2 together. Correspondingly, the protrusion 141 can be made of elastic and tough plastic; the protrusion 141 can also be made of elastic and tough metal; the protrusion 141 can also be made of elastic and tough rubber. This embodiment does not limit the scope of the application.

[0063] In this embodiment, a locking protrusion 22 extends along the direction of the airbag cavity on the side of the airbag 2 near the earphone body 1. Here, the locking protrusion 22 can also have a certain elasticity and toughness, so that the locking protrusion 22 can be inserted into the locking groove 1411 to lock the earphone body 1 and the airbag 2. Correspondingly, the locking protrusion 22 can be made of elastic and tough plastic; the locking protrusion 22 can also be made of elastic and tough metal; the locking protrusion 22 can also be made of elastic and tough plastic; this embodiment does not limit this.

[0064] The adaptive rebound headphones provided in this application embodiment have a snap-fit ​​groove 1411 on the headphone body 1 and a snap-fit ​​protrusion 22 on the side of the airbag 2 near the headphone body 1. The snap-fit ​​protrusion 22 extends into the snap-fit ​​groove 1411 to facilitate snap-fit ​​between the headphone body 1 and the airbag 2, which can ensure the connection strength and make the connection between the airbag 2 and the headphone body 1 more reliable.

[0065] Referring to Figures 1, 2, 3 and 4, an embodiment of this application provides an adaptive rebound earphone, wherein the boss 141 or the snap-fit ​​protrusion 22 is made of an elastic material.

[0066] In this embodiment, the boss 141 or the snap-fit ​​protrusion 22 is made of an elastic material. Here, the elastic material can be made of rubber, plastic, etc.; this embodiment does not limit this.

[0067] The adaptive rebound earphone provided in this application embodiment is made of elastic material for the boss 141 or the snap-fit ​​protrusion 22, so that the snap-fit ​​protrusion 22 can easily extend into the snap-fit ​​groove 1411 of the boss 141.

[0068] Referring to Figures 7 and 8, this embodiment of the application provides an adaptive rebound earphone. On the snap-fit ​​protrusion 22, a dispensing part 23 is formed by recessing the side away from the air bladder cavity along the side away from the earphone body 1. The dispensing part 23 is used for dispensing adhesive. When the snap-fit ​​protrusion 22 extends into the snap-fit ​​groove 1411, the earphone body 1 and the air bladder 2 are bonded together by the adhesive dispensed on the dispensing part 23.

[0069] In this embodiment, the side of the airbag 2 away from the airbag cavity is recessed along the side away from the headphone body 1 to form a dispensing part 23. The dispensing part 23 is used for dispensing adhesive. Here, the dispensing process has the advantage of high precision. The adhesive dispensed on the dispensing part 23 can be selected with high strength and aging resistance. It can adapt to different usage environments and temperature changes while ensuring connection strength, and effectively prevent the airbag 2 from falling off due to long-term use or environmental factors.

[0070] In this embodiment, the location of the adhesive dispensing portion 23 is carefully designed and analyzed, and can be distributed at the edge of the airbag 2 and key stress points to ensure a tight connection between the airbag 2 and the earphone body. In one possible implementation provided in this embodiment, adhesive can be dispensed at the upper and lower ends of the airbag 2 and at the position close to the ear contour contact surface to form a continuous adhesive layer, firmly bonding the airbag 2 to the earphone body.

[0071] In this embodiment, the earphone body 1 and the airbag 2 are connected by a combination of snap fasteners and adhesive application. The positions of the snap fasteners and adhesive application can be coordinated. For example, the snap fasteners can be located on the left and right sides of the airbag 2, while the adhesive application can be located on the top and bottom sides of the airbag 2. Alternatively, the snap fasteners can be located on the top and bottom sides of the airbag 2, while the adhesive application can be located on the left and right sides of the airbag 2. In this way, the combined effect ensures a secure connection while ensuring even force distribution, making the connection between the airbag 2 and the earphone body more robust and reliable.

[0072] In this embodiment, the side of the airbag 2 away from the airbag cavity is recessed along the side away from the headphone body 1 to form a dispensing part 23. The dispensing part 23 is used for dispensing adhesive. It should be noted that the dispensing should not obstruct the exhaust of the main exhaust groove 31 and the secondary exhaust groove 32.
