[0046] The application will be described in further detail below with reference to the drawings and embodiments. It is particularly pointed out that the following embodiments are only used to illustrate the application, but do not limit the scope of the application. Similarly, the following embodiments are only part of the embodiments of the application, and all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the application.

[0047] In the embodiments of the application, the interface plug is fixed on the device body by the locking piece, the device body is provided with a locking piece insertion cavity, the insertion direction of the locking piece when inserted into the locking piece insertion cavity has an angle with the pulling-out direction of the interface plug when pulled out of the connecting port, and the angle can at least avoid a part of the pulling-out force from being transmitted to the locking piece along the insertion direction of the locking piece when the interface plug is pulled out of the connecting port on the device body, which is beneficial to avoid the locking piece from being separated from the limiting structure on the interface plug, and the interface plug can be more firmly connected to the device body.

[0048] An embodiment of an earphone in the application:

[0049] Fig. 1 and Fig. 2 are structural schematic diagrams of an embodiment of an earphone in the present application. As shown in Fig. 1 and Fig. 2, in an embodiment, the earphone can be a bone conduction earphone, which comprises a back hanging 100, an ear hanging 200, an electric control unit 300 and a sound generating unit 400. The back hanging 100 is connected between two electric control units 300, and the ear hanging 200 is connected between the electric control unit 300 on the same side and the sound generating unit 400.

[0050] It can be understood by those skilled in the art that the back hanging 100 can be elastic, so that the back hanging 100 can be elastically deformed and automatically rebound, which facilitates the earphone to form a certain close force with the user's head and can be more stably worn on the user's body (for example, at the face near the ear). The ear hanging 200 can be provided in a shape suitable for the user's ear part, for example, the ear hanging 200 can be an arc structure, which can be hung above the user's ear.

[0051] The electric control unit 300 can comprise a shell 310, a circuit board, a control button 320 and the like, which can realize signal processing and electric control of the earphone. It should be noted that it can be understood that the electric control unit 300 can also comprise a power module, which can power the earphone, and among the two electric control units 300 at the two ends of the back hanging 100, only one electric control unit 300 can comprise a power module, or both electric control units 300 can comprise a power module.

[0052] The sound generating unit 400 is used to abut against the corresponding position of the user's head, which can convert sound into mechanical vibration to realize transmission of sound through the skull, bone labyrinth, inner ear lymph and the like.

[0053] Please refer to Fig. 3 and Fig. 4, Fig. 3 is a partial enlarged view of the connection part of the interface plug 500 of the earphone, and Fig. 4 is a structural exploded view of the earphone main body, the interface plug 500 and the locking piece 600 in Fig. 3. It can be understood in combination with the drawings that the electric control unit 300 is provided with a connection port 360, which can be a charging interface, which can be used for inserting a charging line to charge the power module.

[0054] In an embodiment, the connection port 360 forms a recess on the shell 310, which can accommodate the head end of the charging cable. Referring to FIG. 4 (which can be referred to in conjunction with FIGS. 8 and 9), the connection port 360 includes an exposed port 361 disposed on the shell 310 of the electronic control unit 300, and further includes a charging terminal 362 disposed in the exposed port 361 (the structure of the charging terminal 362 can be referred to in FIGS. 8 and 9). The exposed port 361 is a through hole disposed on the shell 310, which is used to expose the charging terminal 362 disposed in the shell 310, so that the charging cable can be inserted into the shell 310 from the corresponding part of the shell 310 to connect with the charging terminal 362. The shape of the exposed port 361 can match the profile of the charging terminal 362. Those skilled in the art can understand that the charging terminal 362 can be selected in various structural forms, such as a Micro-USB interface, which is characterized by a trapezoidal interface shape, a small socket, and the need to insert a corresponding Micro-USB charging cable for charging. For example, the Type-C interface is characterized by a large socket, an oval shape, support for positive and negative insertion, fast charging speed, high transmission efficiency, and is increasingly adopted by devices. The illustrated embodiment uses the Type-C interface. Of course, the earphone using the Type-C interface needs to be inserted into a corresponding Type-C charging cable for charging. For example, the Lightning interface is an interface unique to Apple, which is used to connect Apple mobile devices and can achieve multiple functions through one interface.

[0055] The charging interface for the charging cable insertion forms exposed conductive contacts. Liquid, dust, foreign matter and the like can enter the charging interface after the charging is completed or in the case of non-use, which can cause damage to the earphone or affect the normal use of the charging interface. In addition, in some cases, the earphone needs to consider the waterproof and dustproof level. To solve this problem, the earphone further includes an interface plug 500, which includes a plug main body 510 and a connecting body 520, the plug main body 510 is used to plug into the connecting port 360, and the connecting body 520 is connected between the plug main body 510 and the earphone main body. It can be understood that for the connecting port 360 including the above-mentioned exposed port 361 and the charging terminal 362, when the plug main body 510 is plugged into the connecting port 360, it can actually be plugged into the exposed port 361. The plug main body 510 can occupy part of the space in the exposed port 361, or can occupy all the space in the exposed port 361. In some other embodiments, the plug main body 510 can also occupy part or all of the space of the charging terminal 362, in addition, according to the different structures of the connecting port 360, the space occupied by the plug main body 510 after being plugged into the connecting port 360 can also be different. The interface plug 500 can be made of various materials, such as silicone, rubber, TPU (Thermoplastic Polyurethanes, thermoplastic polyurethane elastomer rubber) or TPE (Thermoplastic Elastomer, thermoplastic elastomer) and the like. The material of the interface plug 500 can have elasticity, which can be more closely attached to the connecting port 360 through the elastic deformation of itself, thereby better playing a protective role.

[0056] In an embodiment, the shape of the plug main body 510 is adapted to the connecting port 360 on the electronic control unit 300, and the plug main body 510 can be inserted into the connecting port 360 and sealingly fit with the connecting port 360. In a specific embodiment, the plug main body 510 can include a plug-in portion 511 and a limiting portion 513, the plug-in portion 511 is used to be inserted into the inside of the connecting port 360, and the limiting portion 513 is used to be supported on the port rim of the connecting port 360 to limit the insertion depth of the plug main body 510. In order to achieve better sealing effect, two or more sealing protrusions 512 are arranged on the outer peripheral surface of the plug-in portion 511, the sealing protrusions 512 are arranged along the plug-in direction of the interface plug 500, which is similar to two or more sealing rings, which can not only meet the sealing requirement, but also form a friction force to avoid the plug main body 510 from being easily pulled out of the connecting port 360.

[0057] It should be noted that in some other embodiments, the plug main body 510 can also be replaced by other structures, for example, a columnar structure completely adapted to the shape of the inner cavity of the connecting port 360, and the outer peripheral surface of the plug main body 510 can also be a smooth surface, that is, the above-mentioned sealing protrusions 512 can be omitted.

[0058] The connector 520 is used to keep the plug body 510 connected with the earphone body, avoiding the interface plug 500 from being separated from the earphone body and lost. In an embodiment, the connector 520 is connected to one side of the plug body 510 and extends in a direction parallel to the insertion and extraction direction of the interface plug 500. When the interface plug 500 needs to be extracted, the user can exert an extraction force on the plug body 510, which can have an inclined angle relative to the insertion and extraction direction of the interface plug 500, for example, deviated to the side of the interface plug 500 where the connector 520 is arranged. The plug body 510 moves towards the connection port 360 and can be flipped to a certain extent, and finally separated from the connection port 360. During the process, the connector 520 can deform elastically to form a hinge, and can be stretched to produce a certain amount of elastic elongation, facilitating the separation of the plug body 510 from the connection port 360. It should be noted that the connector 520 and the plug body 510 described above can be integrally formed or separately manufactured and assembled together.

[0059] Please refer to FIG. 4. In an embodiment, the connector 520 includes a columnar body 521 and a limiting protrusion 522 protruding from the side of the columnar body 521. The limiting protrusion 522 forms a limiting structure which can cooperate with the corresponding locking member 600 to block the movement of the connector 520 in the extraction direction of the interface plug 500, i.e., the direction towards the connection port 360. Since the locking member 600 is arranged on the side of the connector 520 away from the earphone body, in order to enable the locking member 600 to block the connector 520, the limiting protrusion 522 is arranged on the side of the columnar body 521 close to the locking member 600, i.e., on the side of the columnar body 521 away from the earphone body. The limiting protrusion 522 can be a square protrusion. The side of the limiting protrusion 522 close to the plug body 510 can form a blocking surface which can be blocked by the locking member 600 in the extraction direction of the interface plug 500, thereby preventing the interface plug 500 from being separated from the earphone body. The structure of the locking member 600 will be described below.

[0060] As can be understood from FIGS. 3 and 4, the earphone body is provided with a locking member insertion cavity 330, and the locking member 600 is inserted into the locking member insertion cavity 330. The insertion direction of the locking member 600 when inserted into the locking member insertion cavity 330 has an angle with the extraction direction of the interface plug 500 when extracted from the connection port 360, and the locking member 600 blocks the limiting structure in the extraction direction of the interface plug 500. In some embodiments, the protrusion height of the limiting protrusion 522 used to form the limiting structure can be matched with the locking member 600, and the outer side of the limiting protrusion 522 can be on the same plane as the corresponding side of the locking member 600. In this way, it can be avoided that the limiting protrusion 522 protrudes from the locking member 600 and collides with other objects, and it can be avoided that the connector 520 is damaged or displaced due to the collision, so that the reliability and structural stability are better.

[0061] Depending on the included angle between the plug-in direction of the locking member 600 and the pull-out direction of the interface plug 500, the included angle can at least avoid a part of the pull-out force from being transmitted to the locking member 600 along the plug-in direction of the locking member 600, which is beneficial to avoid the locking member 600 from being separated from the limiting structure, so that the interface plug 500 can be more reliably connected to the earphone main body, and the interface plug 500 can be prevented from being separated due to the pull-out of the interface plug 500, thereby avoiding product damage caused thereby.

[0062] In an embodiment, the plug-in direction and the pull-out direction are perpendicular, which can better avoid the pull-out force of the plug main body 510 from being transmitted to the locking member 600 along the plug-in direction of the locking member 600, and better avoid the separation of the interface plug 500. It can be understood by those skilled in the art that the perpendicular defined in the embodiments of the present application does not mean that the included angle between the two directions is absolutely 90°, and can have a deviation of within 10%. In some other embodiments, the included angle between the plug-in direction and the pull-out direction can also be other angle values.

[0063] In a specific embodiment, the earphone main body has a connecting side surface 340 for connecting the connecting body 520, and the connecting side surface 340 is provided with a mounting groove 341 extending along the pull-out direction, and the connecting body 520 is embedded in the mounting groove 341 along at least a part of the groove depth direction of the mounting groove 341. The mounting groove 341 is beneficial to reduce the height of the connecting body 520 protruding from the earphone main body, and the connection is more stable, and the groove side wall of the mounting groove 341 can limit the connecting body 520, which is beneficial to avoid the connecting body 520 and the limiting structure on the connecting body 520 from being skewed to one side of the width direction of the mounting groove 341, thereby avoiding affecting the cooperation area of the locking member 600 and the limiting structure, and affecting the blocking effect of the locking member 600 on the limiting structure. In some embodiments, the connecting body 520 can be completely embedded in the mounting groove 341, and the side surface of the connecting body 520 away from the groove bottom wall of the mounting groove 341 is on the same plane as the mouth of the mounting groove 341, which is beneficial to avoid the structure stability being affected by the collision between the connecting body 520 and other objects.

[0064] In an embodiment, referring to FIG. 4, the locking member 600 includes a blocking portion 610 and a plug-in portion 620, the blocking portion 610 blocks the limiting protrusion 522 from moving in the direction of the columnar main body 521, the plug-in portion 620 is connected to the blocking portion 610, and the plug-in portion 620 and the blocking portion 610 have an included angle; the locking member plug-in cavity 330 is a plug-in groove provided on the connecting side surface 340, and the plug-in portion 620 is plugged into the plug-in groove. It can be understood that the “blocking” means blocking and preventing, and the blocking portion 610 is a part that can block and prevent the movement of the corresponding component, and can play a limiting role. The blocking portion 610 is beneficial to increase the cooperation area between the limiting structure on the connecting body 520 and the above-mentioned locking member 600, and the blocking effect is better.

[0065] The insertion portion 620 of the locking member 600 can be perpendicular to the blocking portion 610, which can facilitate the installation and possible disassembly of the locking member 600. When installing the locking member 600, the locking member 600 can be fitted to the earphone main body by moving the locking member 600 towards the locking member insertion cavity 330 on the earphone main body in a direction perpendicular to the blocking portion 610. It can be understood that, in order to better prevent the locking member 600 from being separated from the earphone main body, an interference fit or a separation-preventing structure can be provided between the locking member 600 and the earphone main body. For example, the insertion portion 620 of the locking member 600 can be interference-fitted with the cavity side wall of the locking member insertion cavity 330, and the interference-fitted portion can be the portion of the insertion portion 620 on both sides in the plug-in direction of the interface plug 500, or the portion of the insertion portion 620 on both sides in the width direction of the insertion groove; for another example, an adhesive structure, a clamping structure, a screw structure, etc. can be provided between the locking member 600 and the earphone main body as a separation-preventing structure; for another example, after the insertion portion 620 of the locking member 600 is inserted into the insertion cavity 330 and the connecting body 520 is pressed and fixed on the earphone main body, an elastic covering layer can be provided on the outside of the entire earphone, which can cover the locking member 600, the connecting body 520, etc. and be more aesthetically pleasing, and can prevent the insertion portion 620 of the locking member 600 from being separated from the insertion cavity 330 and affecting the reliability of the electronic device. Of course, in some other embodiments, an elastic covering layer can also be provided only on the electronic control unit 300, which can also prevent the locking member 600 from being separated.

[0066] Please continue to refer to FIGS. 3 and 4, and additionally refer to FIG. 5, which is a structural exploded view of the earphone main body and the interface plug 500 in FIG. 3. In a specific embodiment, the insertion portion 620 is provided in two places, and the two insertion portions 511 are provided at opposite ends of the blocking portion 610, and the two insertion grooves are respectively located on both sides of the slot width direction of the mounting slot 341. The provision of the two insertion portions 620 can enable both ends of the blocking portion 610 to be connected to the earphone main body, and the stability of the blocking portion 610 under stress can be better, and the connection between the blocking portion 610 and the earphone main body can be more reliable.

[0067] It can be understood from FIGS. 3, 4 and 5 that, in some embodiments, the locking member 600 can be in the form of a sheet. It should be noted that the locking member 600 in the form of a sheet does not mean that the locking member 600 is in the form of a flat surface, but means that the blocking portion 610 and the insertion portion 620 of the locking member 600 are both in the form of a sheet.

[0068] In other embodiments, the insertion portion 620 of the locking member 600 can also be provided in only one place, for example, only one insertion portion 620 can be provided on one side of the insertion groove width direction, or for another example, one insertion portion 620 can be provided on the side of the earphone main body away from the plug main body 510.

[0069] In one embodiment, the locking member 600 comprises an ear 630 connected to the stop portion 610 on the side away from the limiting protrusion 522, and the ear 630 covers at least a portion of the columnar body 521. The ear 630 provided on the locking member 600 can form a larger mating area with the side wall of the mounting groove 341, and is more conducive to the stable assembly of the locking member 600. In a specific embodiment, the ear 630 can also be omitted.

[0070] Fig. 6 is a perspective view of the interface plug 500 of Fig. 3, and Fig. 7 is a front view of the interface plug 500. As can be understood from Figs. 6 and 7, the columnar body 521 can have an inner side surface facing the groove bottom wall of the mounting groove 341, and the inner side surface is provided with an inner side protrusion 523, and the groove bottom wall of the mounting groove 341 is provided with an embedding groove 342, and the inner side protrusion 523 is embedded in the embedding groove 342. Through the cooperation of the embedding groove 342 and the inner side protrusion 523, the embedding groove 342 can block the inner side protrusion 523 on the connecting body 520, and can also block the protruding portion on the connecting body 521 from moving towards the columnar body 521, thereby more reliably avoiding the connecting body 520 from being separated from the earphone main body. It should be noted that the inner side protrusion 523 provided on the side of the connecting body 520 close to the earphone main body can be a square protrusion as shown in the figure, or can be other shapes, such as a semicircle, a trapezoid, a triangle, a semicircle, etc. The above shapes refer to the cross-sectional shape of the inner side protrusion 523, which is perpendicular to the insertion direction of the interface plug 500. In addition, in a specific embodiment, the limiting protrusion 522 provided on the side away from the earphone main body can be other shapes, such as a semicircle, a trapezoid, a triangle, a semicircle, etc.

[0071] The connection structure of the interface plug 500 and the earphone main body can further refer to Figs. 8 and 9. Fig. 8 is a schematic view of one section of Fig. 3, and the sectioning surface is parallel to the insertion direction of the interface plug 500 and passes through the center of symmetry of the interface plug 500. Fig. 9 is a schematic view of another section of Fig. 3, and the sectioning surface is perpendicular to the insertion direction of the interface plug 500 and passes through the locking member 600. As shown in Fig. 8, the earphone main body is provided with a locking member embedding groove 350 in addition to the locking member insertion cavity 330, i.e. a recess for embedding the locking member 600 to achieve mounting, and the locking member 600 is embedded in the locking member embedding groove 350. The provision of the locking member embedding groove 350 can avoid the protrusion of the locking member 600 from the earphone main body, and can also limit the locking member 600, which is conducive to reliably retaining the locking member 600 on the earphone main body.

[0072] In an embodiment, the plug body 510 has a top surface away from the connecting port 360, and the top surface is provided with an unsealing protrusion 530, which is located on the side of the plug body 510 away from the connecting body 520. By arranging the unsealing protrusion 530, when a user needs to unseal the interface plug 500, the user can exert a force on the unsealing protrusion 530 with a finger, which is inclined towards the connecting body 520, so as to facilitate the user to operate.

[0073] In a specific embodiment, the top surface of the plug body 510 can be provided with a recess 514, which is located on the side of the unsealing protrusion 530 away from the connecting body 520, and the projection of the recess 514 and the unsealing protrusion 530 on the top surface along the pulling-out direction is connected or partially coincides. Those skilled in the art can understand that the recess 514 can be used for the user's finger to extend into, so as to form a larger acting area with the unsealing protrusion 530, and it is beneficial to make the force for pulling out the interface plug 500 inclined towards the side of the interface plug 500 provided with the connecting body 520, so as to more easily unseal the interface plug 500.

[0074] Those skilled in the art can understand that, since the interface plug 500 is inserted into the connecting port 360, the greater the force along the pulling-out direction of the interface plug 500, the more beneficial to the smooth pulling-out of the interface plug 500. Therefore, the unsealing protrusion 530 can be arranged to be inclined, and the distance between the top of the unsealing protrusion 530 and the connecting body is greater than the distance between the bottom of the unsealing protrusion 530 and the connecting body, so that the user's finger can more easily exert a force on the interface plug 500 along the pulling-out direction of the interface plug 500.

[0075] The insertion and pulling-out operation of the interface plug 500 of the earphone described above will be introduced below.

[0076] When charging the earphone, the interface plug 500 needs to be opened first. When operating, the user can place a finger on the side of the cover protrusion 530 away from the connecting body 520, and then apply force to the cover protrusion 530. The force direction can be towards the connecting body 520, and the force direction can form a component force towards the pulling direction of the interface plug 500. Under the operation of the user, the plug main body 510 of the interface plug 500 can have a tendency to tilt and flip to the side of the interface plug 500 where the connecting body 520 is provided, and can have a certain bending deformation, and the connecting body 520 can have a certain tensile deformation. With the increase of the force and the displacement, the plug main body 510 is finally pulled out of the connecting port 360, so as to expose the connecting port 360 for the charging connector to be inserted. Due to the limitation of the connecting body 520, the interface plug 500 will not be completely separated from the earphone main body, and the interface plug 500 can be prevented from being lost. In the above process, the blocking force direction of the locking member 600 to the connecting body 520 is perpendicular to the pulling direction of the interface plug 500, so that the interface plug 500 is not easy to be separated from the earphone main body, and the reliable fixation of the interface plug 500 is facilitated. When inserting the interface plug 500, the end of the interface plug 500 is aligned with the connecting port 360, and then the interface plug 500 is pressed.

[0077] In some related technologies, the connecting body 520 of the interface plug 500 is fixed on the earphone main body by adhesion after being assembled to the set position on the earphone main body. However, such adhesion is very dependent on the reliability, heat resistance, aging degree and other factors of the glue, and is easy to fail during use. The embodiment of the present application can change the force direction, fix the interface plug 500 by the locking member 600, and make the force when opening the interface plug 500 at least partially avoid the pulling direction of the locking member 600. As long as the locking member 600 is firmly fixed, the interface plug 500 is difficult to fall off, so that the mechanical structure is used to realize more reliable fixation of the interface plug 500.

[0078] Fig. 10 is a structural schematic view of the interface plug 500 in another embodiment of an earphone in the present application. It can be understood from Figs. 10 and 11 that the cooperation of the locking member 600 and the limiting structure on the connecting body 520 can also be replaced by other forms. In an embodiment, the connecting body 520 is provided with a plug hole 710, the limiting structure is formed by the plug hole 710, and the locking member 600 is a locking pin 720. The locking pin 720 is inserted into the locking member plug cavity 330 and the plug hole 710 at the same time, and the locking member plug cavity can be a locking pin hole provided on the earphone main body. The above-mentioned locking pin 720 also has an included angle with the pulling direction of the interface plug 500, which can be perpendicular. In this way, when the connecting body 520 is subjected to a force in the pulling direction, the locking pin 720 only needs to bear the tensile force in the pulling direction, and the tensile force will not cause the locking pin 720 to fall out of the locking member plug cavity 330, so as to improve the connection reliability of the interface plug 500.

[0079] In a specific embodiment, the earphone body can be provided with a plug channel 730, the axis of the plug channel 730 is parallel to the pulling direction, the connecting body 520 is plugged into the plug channel 730, the side wall of the plug channel 730 is provided with a locking pin hole, and the locking pin hole forms the locking piece insertion cavity 330. The plug channel 730 can limit the displacement of the connecting body 520 along the axis of the locking pin 720, so that the locking pin 720 can be more effectively prevented from being pulled out, thereby more effectively ensuring the connection reliability of the interface plug 500. Those skilled in the art should understand that one locking pin hole can be arranged on each of the two opposite side walls of the plug channel 730, and the two ends of the locking pin 720 can be inserted into the two locking pin holes respectively, and the middle part of the locking pin 720 is used for fixing the connecting body 520 of the interface plug 500.

By means of the angle between the insertion direction of the locking piece 600 when being inserted into the locking piece insertion cavity 330 and the pulling direction of the interface plug 500, at least part of the force acting on the interface plug 500 along the pulling direction will not act on the insertion direction of the locking piece 600, so that the locking piece 600 can be prevented from being disabled, and the interface plug 500 can be prevented from being pulled out.
