[0002] (Technical Field) This application relates to the technical field of consumer electronics products, particularly to earphones.

Background Art

[0003] With the development of society, the application range of earphones has become increasingly wide, and they are widely used when listening to music or enjoying entertainment in office environments and all places.

[0004] Currently, in the production process of earphones, generally, an inner bracket with an adhesive distribution groove is injection-molded first, then a silica gel layer is injection-molded outside the inner bracket, and an adhesive is distributed into the adhesive distribution groove to bond the upper cover of the earphone and the inner bracket. However, the top surface of the current adhesive distribution groove is generally flush with the top surface of the silica gel layer. In the process of injection-molding the silica gel layer, silicone oil is likely to flow into the adhesive distribution groove, affecting the bonding effect between the adhesive in the adhesive distribution groove and the upper cover of the earphone.

[0005] All current earphones have charging contacts on the earphones themselves, and charge the earphones via the earphone case after they are placed in the case. In order to ensure the appearance of the earphones, conventional technology generally places the charging contacts on the side of the earphone that fits against the skin, increasing the shortest distance between the two charging electrodes to prevent short circuits between the charging electrodes due to sweat, water droplets, dust, etc. For example, paragraph 137 of the utility model patent with publication number CN217159949 U and the name "earphone" states the following: The two charging electrodes may be placed so as not to be visible when worn, for example, both facing the user's skin, thus maintaining the appearance quality of the earphones. However, because both charging electrodes face the user's skin, when the user sweats, the sweat can easily cause short-circuit failures in the earphones.

[0006] Current earphones typically place function buttons such as power switches and volume buttons on the front of the sound-producing unit, facing the user's ear. This design makes these buttons prone to accidental contact, for example, when a user is lying down and resting, which can easily lead to accidental touches and negatively impact the user experience. To overcome this problem, the solution used in the Bluetooth® earphone with publication number CN216795245U, named "Anti-Accidental Touch," involves covering the buttons with protective covers to prevent accidental touches during use. However, this solution has a complex structure and significantly impacts the overall appearance of the earphone.

[0007] Based on the above, existing earphones have problems such as poor assembly rigidity and poor performance. [Overview of the project]

[0045] The achievement of the objectives, functional features, and advantages of this application will be further described with reference to the drawings, along with the examples provided. [Modes for carrying out the invention]

[0046] The following clearly and completely describes the technical concepts in the embodiments of this application, linking them to the drawings of the embodiments. Clearly, the embodiments described are only a subset of the embodiments of this application, not all of them. All other embodiments derived from the embodiments of this application, without requiring any creative effort by a person skilled in the art, are all within the scope of protection of this application.

[0047] First, the definitions of the wearing state, the anterior, posterior, upper, and lower sides of the ear, the sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, horizontal axis, and the X, Y, and Z directions as per this specification will be explained.

[0048] The definition of the wearing state is as follows: Since a simulator including the head and its (left and right) ears (see Figure 1), such as GRASKB0065, can be manufactured in accordance with ANSI: S3.36, S3.25 and IEC: 60318-7 standards, descriptions in this application such as "the user is wearing the earphones" or "the earphones are in the wearing state" may refer to the earphones being attached to the ear parts of the aforementioned simulator. Based on this, the "wearing state" described in this application may refer to the normal wearing state after the earphones have been attached to the ear parts of the aforementioned simulator, and for the convenience of description, the aforementioned normal wearing state may be shown from the front, back, etc. of the ear parts. Of course, since there are individual differences among users, the actual wearing state of the earphones may differ to some extent from the aforementioned normal wearing state.

[0049] The definitions of the anterior, posterior, superior, and inferior parts of the ear are as follows: In this application, "anterior part of the ear" is a concept in contrast to "posterior part of the ear," with the former being the side of the ear away from the head and the latter being the side of the ear toward the head; in this application, the superior part of the ear is the side closer to the upper edge of the ear, with the upper edge being the part of the helix closest to the triangular fossa of the ear; the inferior part of the ear is the side closer to the lower edge of the ear, with the lower edge being the part of the helix closest to the earlobe; all of these refer to the user's ear.

[0050] The definitions of the sagittal plane, coronal plane, horizontal plane, sagittal axis, coronal axis, and horizontal axis of the human body are as follows: As is well known, in fields such as medicine and anatomy, the three basic cross-sections of the human body—the sagittal plane, coronal plane, and horizontal plane—and the three basic axes—the sagittal axis, coronal axis, and vertical axis—can be defined. Here, the sagittal plane is a cross-section perpendicular to the ground, created along the anterior-posterior direction of the body, and it divides the human body into two parts, left and right. The coronal plane is a cross-section perpendicular to the ground, created along the lateral direction of the body, and it divides the human body into two parts, front and back. The horizontal plane is a cross-section parallel to the ground, created along the vertical direction of the body, and it divides the human body into two parts, upper and lower. Accordingly, the sagittal axis is the axis that runs perpendicular to the coronal plane along the anterior-posterior direction of the body, the coronal axis is the axis that runs perpendicular to the sagittal plane along the lateral direction of the body, and the vertical axis is the axis that runs perpendicular to the horizontal plane along the posterior-posterior direction of the body.

[0051] The definitions of the X, Y, and Z directions are as follows: As shown in Figure 2, for the sake of convenience, the X, Y, and Z directions are defined as follows: the X direction is parallel to the sagittal axis and points forward of the human body; the Y direction is parallel to the coronal axis and points to the right side of the human body (pointing outward along the plane of the paper in Figure 2); and the Z direction is parallel to the vertical axis and points upward of the human body.

[0052] The above definitions of directions are merely for convenience of description, and the X, Y, and Z directions may be defined arbitrarily as long as they conform to the principles of this proposed technology, and include, but are not limited to, definitions such as axial symmetry and angular symmetry of the above directions.

[0053] As shown in Figure 3, the first embodiment of the earphone of this application includes an ear hook and a main body 2, the main body 2 being installed at one end of the ear hook.

[0054] When worn, the main body 2 is fitted and installed on the front side of the ear portion. The main body 2 has a circumferential side surface that extends from the front side near the ear portion toward the front side away from the ear portion, and the operating device 30 is installed on the circumferential side surface.

[0055] This embodiment takes into consideration that current earphones generally have the operating device 30 installed on the side of the main unit 2 facing the user's ear, making accidental contact easy. Therefore, this embodiment mainly changes the installation position of the operating device 30, and installs the operating device 30 on the side surface of the main unit 2 that extends from the front side close to the ear towards the front side away from the ear. This not only makes it less likely to come into contact with other parts of the body, but also does not affect the user's activity or rest, prevents accidental contact during activity or rest, and further enhances the user experience.

[0056] In one embodiment, the operating device 30 is installed on the first side surface 5 that extends toward the upper edge of the lug portion of the side surface.

[0057] Referring again to Figures 2-4, in this embodiment, the main body 2 may be set to a substantially tetrahedral structure, the first side surface 5 is the side of the main body 2 toward the upper edge of the ear portion, the second side surface 6 of the main body 2 is the side of the main body closer to the user's ear, i.e., the side where the sound-producing holes are installed, and the third side surface 7 is the side opposite the second side surface 6 and adjacent to the first side surface 5.

[0058] In the current earphones described above, the operating device 30 is generally installed on the side of the main body 2 facing the user's ear, that is, the operating device 30 is installed on the third side surface 7. In this embodiment, accidental contact can be further avoided by installing the operating device 30 on a first side surface that is adjacent to the second side surface 6 and the third side surface 7, extending from the front side closer to the ear towards the front side away from the ear.

[0059] Furthermore, in this embodiment, when worn, the angle α between the first circumferential surface 5 and the horizontal plane of the human body is 30° to 45°. Setting the angle between the first circumferential surface 5 and the horizontal plane to 30° to 45° is ergonomically sound, and by installing the operating device 30 on the first circumferential surface 5 where the angle with the horizontal plane of the human body is 30° to 45°, the operation of the operating device by the user is facilitated, thereby enhancing the user experience.

[0060] In other embodiments, the angle between the first circumferential surface 5 and the horizontal plane of the human body may be set according to the shape of the ear, for example, preferably 32° to 43°, and more preferably 30° to 40°, and this application is not limited to this angle.

[0061] In order to further enhance the user experience and facilitate the user's operation of the operating device 30, in this embodiment, the panel of the operating device 30 protrudes from the first side surface 5.

[0062] Referring to Figure 4, in this embodiment, a power button 4 is installed on the surface of the head or ear area facing the back of the ear hook. This power button 4 is a physical button, and by using a physical button, accidental contact can be further prevented.

[0063] Referring to Figures 5 and 6, the following embodiment may also be a second embodiment of the earphone of this application, based on the first embodiment shown in Figures 3 and 4.

[0064] In this embodiment, the operating device 30 includes a main control chip and a sensor module, the sensor module including a pressure sensor for receiving pressing gestures and a capacitive touch sensor for receiving touch gestures, the touch gestures including normal touch gestures such as touch-and-hold touch and swipe. The main control chip is electrically connected to the pressure sensor and the capacitive touch sensor, respectively.

[0065] This embodiment installs two different types of sensors and receives two types of gestures, pressing and touching, using different sensors, namely a pressure sensor and a capacitive touch sensor. By separating the pressure signal generated by pressing and the touch signal generated by touching, it is possible to prevent erroneous operation and further prevent accidental contact.

[0066] Furthermore, the touch gesture that capacitive touch sensors accept is the swipe gesture. Capacitive touch sensors are used to accept only swipe gestures, thereby shielding them from touch-and-hold gestures, which are similar to press gestures. To achieve a press operation, a certain amount of pressure must be applied to the pressure sensor. Moreover, this better separates the two types of gestures and prevents accidental contact.

[0067] The operating principles of the pressure sensor and capacitive touch sensor in this embodiment will be described below.

[0068] In this embodiment, in order to prevent accidental triggering due to pressing when picking up the earphones, a trigger threshold is set for the pressure sensor based on actual empirical values, and the relevant operation of the earphones is triggered only when the pressing pressure is equal to or greater than the trigger threshold. In one preferred embodiment, the trigger threshold is set to 120g in this embodiment.

[0069] If the pressing pressure is less than 120g, the swipe is triggered; if the pressing pressure is 120g or greater, the swipe is blocked, only the pressing is triggered, the pressure sensor detects deformation, a voltage change occurs, and the main control chip determines whether or not there is pressing in response to the voltage change. In other embodiments, the trigger threshold may be set based on actual empirical values.

[0070] The capacitive touch sensor in this embodiment has a self-calibration function. Due to environmental changes, the capacitance is maintained at a certain value, and after 10 seconds, self-calibration is considered necessary. This maintained sampled value replaces the original reference value as a new reference value (i.e., the actual surface value).

[0071] If the reference value becomes greater than the sampled value due to environmental changes, calibration will be performed immediately, and the existing sampled value will be used as the reference value.

[0072] As shown in Figure 6, in this embodiment, the operating device 30 includes panels for contacting the user's limbs, a capacitive touch sensor, and a pressure sensor, which are stacked sequentially from the outside to the inside.

[0073] To better recognize swipe gestures, at least three capacitive touch sensors are arranged sequentially along the extending direction of the panel, preferably three in this embodiment.

[0074] As shown in Figures 5 and 6, pins Touch1, Touch2, and Touch3 of the main control chip are electrically connected to the three capacitive touch sensors, respectively, and pin Touch_SH of the main control chip is electrically connected to the pressure sensor.

[0075] In this embodiment, three positioning points, i.e., three pads for welding the three capacitive touch sensors, are provided, and each of the three capacitive touch sensors is a three-touch sheet, which is installed in a continuous manner.

[0076] When determining whether or not a gesture is a swipe gesture, the determination may be made by the duration of time elapsed when swiping two adjacent touch sheets. If the duration falls within a threshold range, it is considered a swipe gesture. This threshold may be set based on actual experience, for example, in this embodiment, preferably greater than 50ms and less than 1s.

[0077] Specifically, when the touch sheet of the first capacitive touch sensor is swiped, the change in capacitance is transmitted to the main control chip to obtain a timestamp t1. When the touch sheet of the second capacitive touch sensor is pressed, the change in capacitance is transmitted to the main control chip to obtain a timestamp t2. If the difference between t2 and t1 is greater than 50ms and less than 1s, it may be considered a swipe gesture.

[0078] In this embodiment, a reinforcing metal sheet is laminated between the pressure sensor and the capacitive touch sensor, and the reinforcing metal sheet may preferably be sheet steel.

[0079] The reinforcing metal sheet strengthens the overall strength of the operating device and extends its service life.

[0080] In this embodiment, the reinforcing metal sheet has grooves on the side facing the pressure sensor, and these grooves are installed in line with the extending direction of the panel, thereby reducing the contact area with the pressure sensor and concentrating the pressure in the central part, thereby enabling better transmission of pressure to the pressure sensor. Preferably, in this embodiment, two grooves are installed parallel to each other with a gap between them.

[0081] This application proposes an earphone, and referring to Figures 7 to 9, the first embodiment of the earphone of this application includes a main body 2, a connecting part 1, and a battery part 3, the connecting part 1 connects the main body 2 and the battery part 3, the battery part 3 includes a battery case, a battery (not shown), and a charging structure 40, the battery is installed inside the battery case, and the charging structure 40 is installed inside the battery case.

[0082] When the earphones are worn, the first surface of the battery case contacts the back of the auricle, the second surface of the battery case contacts the scalp near the back of the auricle, and the charging structure 40 is located on the surface of the battery case that does not come into contact with the skin. Because the charging structure 40 does not come into contact with the user's skin when worn, it is possible to prevent the user's sweat from wetting the charging structure 40 and causing a short circuit, and to prevent dirt on the user's skin from contaminating the charging structure 40 and causing charging failure or poor contact during charging, and further extend the lifespan of the earphones.

[0083] Referring to Figures 10 to 12, the charging structure 40 includes a first charging connector 50 and a second charging connector 60 installed at intervals, where one of the charging connectors is a positive-pole charging connector and the other is a negative-pole charging connector. This embodiment does not limit the specific mounting order of the first charging connector 50 and the second charging connector 60.

[0084] As one embodiment, referring to Figures 10 to 12, in order to facilitate removal and maintenance of the charging structure 40, this embodiment installs the charging structure 40 in a removable manner in the battery case. Specifically, the battery case is provided with a locking groove, and the charging structure 40 is provided with a corresponding locking structure 70, and the charging structure 40 is locked into the locking groove via the locking structure 70.

[0085] In another embodiment, to improve the assembly stability of the charging structure 40, the charging structure 40 and the battery case may be integrally molded.

[0086] Based on the first embodiment shown in Figures 7 to 9, we propose a second embodiment of the earphone of this application.

[0087] In this embodiment, the battery case includes a third surface, a fourth surface, and a fifth surface, the third surface being the surface facing the first surface of the battery case, the fourth surface facing the second surface, and the fifth surface being the bottom surface of the battery case, and the charging structure 40 is installed on at least one of the third surface, the fourth surface, and the fifth surface. Any one of the third surface, the fourth surface, and the fifth surface does not come into contact with the user's skin, and by installing the charging structure 40 on at least one of the third surface, the fourth surface, and the fifth surface that does not come into contact with the user's skin, it is possible to prevent the user's sweat from wetting the charging structure 40 and causing a short circuit, as well as to prevent dirt on the user's skin from contaminating the charging structure 40 and causing charging failure or poor contact during charging, further extending the lifespan of the earphones, and also improving the user experience by avoiding pressure on the user from the charging structure 40.

[0088] Referring to Figure 11, a third embodiment of the earphone of this application is proposed based on the first embodiment shown in Figures 7 to 9.

[0089] In this embodiment, a magnetic adsorption structure is installed inside the battery case, and the magnetic adsorption structure is in close proximity to the charging structure 40.

[0090] The magnetic adsorption structure includes at least one magnetic block 80, which is installed between a first charging connector 50 and a second charging connector 60, and the distance between the first charging connector 50 and the second charging connector 60 is greater than the length of the magnetic block 80.

[0091] During charging, the magnetic adsorption structure and the magnets inside the earphone charging box attract each other, firmly connecting the charging contacts 90 of the first charging connector 50 and the second charging connector 60 to the charging head inside the charging box, thus facilitating charging.

[0092] In this embodiment, a metal plating film is provided on the charging contacts 90 of the first charging connector 50 and the second charging connector 60.

[0093] The metal plating film has a conductive function, and during charging, the metal plating film on the first charging connector 50 and the second charging connector 60 comes into contact with the charging head inside the charging box, thereby enabling charging of the earphones.

[0094] In this embodiment, the entire battery unit 3 may be set to one of the following shapes: a tetrahedral structure, a cylindrical structure, or a structure with an elliptical cross-section, or any other shape. The charging structure 40 is installed at the rear end of the battery unit 3, which has a tetrahedral structure, a cylindrical structure, or a structure with an elliptical cross-section, and in a position that does not come into contact with the skin of the user's ear. When the user is wearing the earphones, the charging structure 40 is not visible from the front or the side of the user, and this also prevents sweat from coming into contact with the charger 4 and causing a short circuit failure, while also improving aesthetics.

[0095] Referring to Figure 13, a fourth embodiment of the earphone of this application is proposed based on the first embodiment shown in Figures 7 to 9.

[0096] In this embodiment, the connecting part 1 is an ear hook, and the ear hook includes an ear hook body, with a metal support member 100 installed inside the ear hook body.

[0097] The ear hook is arc-shaped to fit the user's ear, and the connection point between one end of the ear hook and the main body 2 is the support point of the earphone. The gravitational force acting on the ear hook from the position of the support point toward the battery unit 3 gradually increases. The support point of the earphone is the point that receives the main force when the user is wearing the earphone, and the gravitational force acting on the ear hook from the position of the support point toward the battery unit 3 gradually increases. By using gravity to attach the entire earphone to the user's ear, the entire earphone can be perfectly fitted to the user's ear, preventing it from falling out, improving the user's wearing comfort, and enhancing the user experience.

[0098] This embodiment, by using a metal support member 100, not only reinforces the strength of the ear hook and prevents bending due to gravity, but also makes it easier for the user to adjust the position of the earphone's support point according to their actual needs, thereby improving wearing comfort.

[0099] Here, the metal support member 100 may be made of a nickel-titanium alloy or titanium wire, and this embodiment is not limited to these.

[0100] A flexible circuit board is further installed inside the ear hook, and the flexible circuit board is in close proximity to the metal support member 100.

[0101] The flexible circuit board may be installed so as to cover a part of the metal support member 100, or so as to cover the entire metal support member 100, and this embodiment does not limit the specific fitting structure between the flexible circuit board and the metal support member 100.

[0102] This application proposes that by placing the charging structure on a surface of the battery case that does not come into contact with the skin, the charging structure does not come into contact with the user's skin when worn. This prevents the user's sweat from wetting the charging structure and causing a short circuit, and also prevents dirt on the user's skin from contaminating the charging structure, which can cause charging failure or poor contact during charging. Furthermore, it can extend the lifespan of the earphones.

[0103] This application proposes an earphone, and referring to Figures 14 to 17, a first embodiment of the earphone of this application includes a connector 1, a main body 2, and a battery 3, wherein the connector 1 connects the main body 2 and the battery 3, the main body 2 includes a first lower case 201 and a first upper cover 202 bonded to the first lower case 201, the first lower case 201 includes a first inner bracket 203 and a first silica gel coating layer 204 covering the outer circumference of the first inner bracket 203, a first adhesive distribution groove 205 is provided on the top of the first inner bracket 203, a first adhesive seal rib 206 is provided on the outer wall of the first adhesive distribution groove 205, the first adhesive seal rib 206 is formed by silica gel adhesive sealing, and the top surface of the first adhesive seal rib 206 is higher than the top surface of the first silica gel coating layer 204.

[0104] By making the top surface of the first adhesive sealing rib 206 higher than the top surface of the first silica gel coating layer 204, when the first silica gel coating layer 204 is injection molded, the first adhesive sealing rib 206 prevents silicone oil from flowing into the first adhesive distribution groove 205 of the first inner bracket 203, thereby preventing the silicone oil from affecting the adhesion effect between the adhesive in the adhesive distribution groove and the upper cover of the earphone, and thereby increasing the assembly strength between the upper cover of the earphone and the first inner bracket 203.

[0105] A stepped structure is installed on the outer wall of the first adhesive sealing rib 206, and a first projection 207 is installed on the top of the first silica gel coating layer 204, extending toward the stepped structure. The first projection 207 is located on the stepped structure, and the top surface of the first projection 207 is lower than the top surface of the first adhesive sealing rib 206.

[0106] In this embodiment, by installing the stepped structure on the outer wall of the first adhesive seal rib 206 and positioning the first protrusion 207 on the stepped structure, the assembly of the first silica gel coating layer 204 and the first inner bracket 203 can be made stronger and more secure. Furthermore, by making the top surface of the first protrusion 207 lower than the top surface of the first adhesive seal rib 206, it is possible to further avoid silicone oil flowing into the adhesive distribution groove and affecting the adhesion effect between the adhesive and the upper cover of the earphone.

[0107] An engagement groove corresponding to the first adhesive sealing rib 206 is provided at the end of the first upper cover 202. The outer wall of the engagement groove abuts against the top surface of the first projection 207, and the inner wall of the engagement groove protrudes into the first adhesive distribution groove 205 and abuts against the bottom surface of the first adhesive distribution groove 205. This strengthens and secures the bond between the first upper cover 202, the first silica gel coating layer 204, and the first inner bracket 203. It also prevents silicone oil from flowing into the adhesive distribution groove and affecting the adhesion effect between the adhesive and the upper cover of the earphone, and provides a waterproofing effect, preventing water from the outside of the main body 2 from entering the first inner bracket 203, thereby increasing the lifespan of the earphone.

[0108] In one embodiment, the first inner bracket 203 is formed by plastic injection molding, and the first adhesive distribution groove 205 is integrally molded.

[0109] A side mesh bracket 208 is installed on one side of the main body 2, and the side mesh bracket 208 is fitted into the first silica gel coating layer 204. A first horn front case 209 is installed at the bottom of the main body 2.

[0110] Referring to Figures 14, 15, 18, and 19, a second embodiment of the earphone of this application is proposed, in which the battery unit 3 includes a second lower case 301 and a second upper cover 302 bonded to the second lower case 301, a second horn front case 308 is installed at the bottom of the second lower case 301, the second lower case 301 includes a second inner bracket 303 and a second silica gel coating layer 304 covering the outer circumference of the second inner bracket 303, a second adhesive distribution groove 305 is installed at the top of the second inner bracket 303, a second adhesive seal rib 306 is installed on the outer wall of the second adhesive distribution groove 305, the second adhesive seal rib 306 is formed by silica gel adhesive sealing, and the top surface of the second adhesive seal rib 306 is higher than the top surface of the second silica gel coating layer 304.

[0111] By making the top surface of the second adhesive sealing rib 306 higher than the top surface of the second silica gel coating layer 304, when the second silica gel coating layer 304 is injection molded, the second adhesive sealing rib 306 prevents silicone oil from flowing into the second adhesive distribution groove 305 of the second inner bracket 303, thereby preventing the silicone oil from affecting the adhesion effect between the adhesive in the adhesive distribution groove and the upper cover of the earphone, and improving the assembly strength between the upper cover of the earphone and the second inner bracket 303.

[0112] A stepped structure is installed on the outer wall of the second adhesive sealing rib 306, and a second projection 307 is installed on the top of the second silica gel coating layer 304, extending toward the stepped structure. The second projection 307 is located on the stepped structure, and the top surface of the second projection 307 is lower than the top surface of the second adhesive sealing rib 306.

[0113] In this embodiment, by installing the stepped structure on the outer wall of the second adhesive seal rib 306 and positioning the second protrusion 307 on the stepped structure, the assembly of the second silica gel coating layer 304 and the second inner bracket 303 can be made stronger and more secure. Furthermore, by making the top surface of the second protrusion 307 lower than the top surface of the second adhesive seal rib 306, it is possible to further avoid silicone oil flowing into the adhesive distribution groove and affecting the adhesion effect between the adhesive and the upper cover of the earphone.

[0114] An engagement groove corresponding to the second adhesive sealing rib 306 is provided at the end of the second upper cover 302. The outer wall of the engagement groove abuts against the second projection 307, and the inner wall of the engagement groove protrudes into the second adhesive distribution groove 305 and abuts against the bottom of the second adhesive distribution groove 305. This makes the bond between the second upper cover 302, the second silica gel coating layer 304, and the second inner bracket 303 stronger and more secure, preventing silicone oil from flowing into the adhesive distribution groove and affecting the adhesion effect between the adhesive and the upper cover of the earphone. In addition, it provides a waterproofing effect, preventing water from outside the battery unit 3 from entering the second inner bracket 303, and extending the lifespan of the earphone.

[0115] In one embodiment, the width of the second adhesive seal rib 306 is 1.8 mm or less, which increases the internal space volume of the battery section 3 and facilitates the assembly of the battery. Of course, in other embodiments, the width of the second adhesive seal rib 306 may be set according to actual needs, and this embodiment is not limited thereto.

[0116] The beneficial effects of the earphones of this application are as follows: By making the top surface of the first adhesive seal rib higher than the top surface of the first silica gel coating layer, when the first silica gel coating layer is injection molded, the first adhesive seal rib prevents silicone oil from flowing into the first adhesive distribution groove of the first inner bracket, thereby preventing the silicone oil from affecting the adhesion effect between the adhesive in the adhesive distribution groove and the upper cover of the earphone, and increasing the assembly strength between the upper cover of the earphone and the first inner bracket.
