An embodiment of the application is an earphone:

Fig. 1 and 2 are schematic structural views of an earphone according to an embodiment of the present application, as shown in fig. 1 and 2, in an embodiment, the earphone may be a bone conduction earphone, including a rear hook 100, an ear hook 200, an electronic control unit 300, and a sound generating unit 400. The rear hook 100 is connected between the two electronic control units 300, and the ear hook 200 is connected between the electronic control unit 300 and the sounding unit 400 on the same side.

Those skilled in the art will appreciate that the rear suspension 100 may be resilient to allow the rear suspension 100 to elastically deform and automatically spring back, which facilitates the headset to form a certain abutment with the user's head and may be more stably worn on the user's body (e.g., near the face of the ear). The ear hook 200 may be configured to fit the ear portion of the user, e.g., the ear hook 200 may be an arcuate structure capable of hanging over the user's ear.

The electronic control unit 300 may include a housing 310, a circuit board, control buttons 320, etc., which enable signal processing and electronic control of the headset. It should be noted that, it is understood that the electronic control unit 300 may further include a power module, where the power module is capable of supplying power to the earphone, and only one electronic control unit 300 may include the power module, or both electronic control units 300 may include the power module, of the two electronic control units 300 at two ends of the rear suspension 100.

The sound generating unit 400 is used for being abutted against the corresponding position of the head of the user, can convert sound into mechanical vibration, and can realize sound transmission through skull, bone labyrinth, inner ear lymph fluid and the like.

Referring to fig. 3 and 4, fig. 3 is a partial enlarged view of a connection portion of the interface plug 500 of the earphone, and fig. 4 is an exploded view of the structure of the earphone body, the interface plug 500 and the locking member 600 of fig. 3. As can be appreciated in conjunction with the drawings, the electronic control unit 300 is provided with a connection port 360, and the connection port 360 may be a charging interface, where the charging interface can be used for inserting a charging wire to charge the power module.

In one embodiment, the connection port 360 forms a recess in the housing 310 into which the head end of the charging cord can be inserted. Referring to fig. 4 (fig. 8 and 9 may be simultaneously referred to), the connection port 360 includes an exposure port 361 provided on the housing 310 of the electronic control unit 300, and further includes a charging terminal 362 provided in the exposure port 361 (the structure of the charging terminal 362 may be referred to fig. 8 and 9). The exposure port 361 is a through hole provided on the housing 310 for exposing the charging terminal 362 provided in the housing 310 such that the charging wire can be inserted into the housing 310 from the corresponding portion of the housing 310 to be connected with the charging terminal 362. The shape of the exposure port 361 may be matched with the contour of the charging terminal 362. Those skilled in the art will appreciate that the charging terminal 362 may be selected from a variety of structural forms, such as a Micro-USB interface, which is characterized by a trapezoidal interface shape, a smaller socket, and a corresponding Micro-USB charging wire to be inserted for charging. And if the Type-C interface is adopted, the Type-C interface is characterized in that the socket is large, the socket is oval in shape, forward and reverse insertion is supported, the charging speed is high, the transmission efficiency is high, more and more devices are adopted, and the Type-C interface is adopted in the illustrated embodiment. Of course, headphones using the Type-C interface require insertion of a correspondingly shaped Type-C charging cord for charging. As another example, a lighting interface, which is an interface unique to apple companies, is used to connect to mobile devices of apples, and multiple functions can be implemented through one interface.

The charging interface into which the charging wire is inserted may form an exposed conductive contact, and after charging is completed or under the condition of no use, liquid, dust, foreign matters and the like may enter the charging interface, which may cause damage to the earphone or affect the normal use of the charging interface. In addition, in some cases, the earphone needs to consider waterproof and dustproof grades. To solve this problem, the earphone further includes an interface plug 500, the interface plug 500 including a plug body 510 and a connector 520, the plug body 510 being for plugging the connection port 360, the connector 520 being connected between the plug body 510 and the earphone body. It will be appreciated that, for the connection port 360 including the exposure port 361 and the charging terminal 362, the plug body 510 may be plugged into the exposure port 361 when the plug body 510 is plugged into the connection port 360, and the plug body 510 may occupy a part of the space in the exposure port 361 or may occupy the whole space of the exposure port 361. In some other embodiments, the plug body 510 may also occupy a part or all of the space of the charging terminal 362, and in addition, the space occupied by the plug body 510 after being plugged into the connection port 360 may be different according to the different structures of the connection port 360. The interface plug 500 may be made of a variety of materials, such as silicone rubber, TPU (Thermoplastic Polyurethanes, thermoplastic polyurethane elastomer rubber), TPE (Thermoplastic Elastomer ), or the like. The material of the interface plug 500 may have elasticity, so that the interface plug can be more tightly attached to the connection port 360 through elastic deformation of the interface plug itself, thereby better playing a protective role.

In one embodiment, plug body 510 is shaped to fit connection port 360 on electronic control unit 300, and plug body 510 is capable of being inserted into connection port 360 and sealingly engaged with connection port 360. In one embodiment, the plug body 510 may include a plug portion 511 for insertion into the connection port 360 and a stopper portion 513 for supporting on the rim of the connection port 360 to limit the insertion depth of the plug body 510. In order to achieve a better sealing effect, two or more sealing protrusions 512 are disposed on the outer circumferential surface of the plugging portion 511, and the sealing protrusions 512 are arranged along the plugging direction of the interface plug 500, similar to two or more sealing rings, so that not only can the sealing requirements be met, but also friction force can be formed to prevent the plug main body 510 from being easily separated from the connection port 360.

It should be noted that, in some other embodiments, the plug body 510 may be replaced by other structures, for example, a columnar structure that completely matches the shape of the inner cavity of the connection port 360, and the outer peripheral surface of the plug body 510 may be a smooth surface, i.e., the sealing protrusion 512 may be omitted.

The connector 520 is used to keep the plug body 510 connected with the earphone body, so as to avoid the interface plug 500 from being lost when being separated from the earphone body. In one embodiment, the connector 520 is connected to one side of the plug body 510 and extends parallel to the insertion and extraction direction of the interface plug 500. When it is desired to pull out the interface plug 500, the user may apply a pull-out force to the plug body 510 that may have an oblique angle with respect to the direction of insertion of the interface plug 500, such as being biased toward the side of the interface plug 500 where the connector 520 is disposed, and the plug body 510 may move in the direction of the connection port 360 and may turn over somewhat, eventually disengaging from the connection port 360. In this process, the connector 520 may hinge by virtue of its elastic deformation and may be stretched to provide a certain amount of elastic elongation to facilitate detachment of the plug body 510 from the connection port 360. The connector 520 and the plug body 510 may be integrally formed, or may be manufactured separately and assembled.

Referring to fig. 4, in one embodiment, the connector 520 includes a cylindrical main body 521 and a limiting protrusion 522, the limiting protrusion 522 protrudes from a side surface of the cylindrical main body 521, and the limiting protrusion 522 forms a limiting structure, and the limiting structure can cooperate with the corresponding locking member 600 to block the connector 520 from moving along the pulling direction of the interface plug 500, that is, the direction of the connection port 360. Since the locking member 600 is disposed at a side of the connection body 520 away from the earphone body, in order for the locking member 600 to form a barrier to the connection body 520, the limit projection 522 is disposed at a side of the column-shaped body 521 close to the locking member 600, i.e., at a side of the column-shaped body 521 away from the earphone body. The limit protrusion 522 may be a square protrusion, and a side of the limit protrusion 522 near the plug body 510 may form a blocking surface, which may be blocked by the locking piece 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.

As can be understood from fig. 3 and fig. 4, the earphone body is provided with a locking piece inserting cavity 330, the locking piece 600 is inserted into the locking piece inserting cavity 330, an included angle is formed between the inserting direction of the locking piece 600 when the locking piece 600 is inserted into the locking piece inserting cavity 330 and the extracting direction of the interface plug 500 when the connection port 360 is extracted, and the locking piece 600 blocks the limiting structure along the extracting direction of the interface plug 500. In some embodiments, the height of the protrusion of the limiting protrusion 522 used to form the above-mentioned limiting structure may be matched with the locking piece 600, and the outer side surface of the limiting protrusion 522 may be on the same plane with the corresponding side surface of the locking piece 600, so that the limiting protrusion 522 may be prevented from colliding with other objects when protruding from the locking piece 600, and the connector 520 may be prevented from being damaged or displaced due to the collision, so that reliability and structural stability are better.

By means of the included angle between the plugging direction of the locking piece 600 and the pulling-out direction of the interface plug 500, the included angle can at least avoid a part of pulling-out force being transmitted to the locking piece 600 along the plugging direction of the locking piece 600, which is beneficial to avoiding the locking piece 600 from being separated from the limiting structure, so that the interface plug 500 can be more reliably connected to the earphone body, the interface plug 500 is reduced or avoided from being separated due to pulling out the interface plug 500, and further the damage to products caused by the separation is avoided.

In one embodiment, the plugging direction is perpendicular to the unplugging direction, so that the unplugging force of the plug body 510 is better prevented from being transmitted to the locking member 600 along the plugging direction of the locking member 600, and the interface plug 500 is better prevented from being separated. It will be appreciated by those skilled in the art that the vertical defined in the embodiments of the present application does not define an angle of 90 ° between the two directions, and may have a deviation of within 10%. In some other embodiments, the angle between the connection direction and the extraction direction may be other angle values.

In a specific embodiment, the earphone body has a connection side 340 to which the connector 520 is connected, the connection side 340 is provided with a mounting groove 341 extending in the pull-out direction, and at least a portion of the connector 520 along the groove depth direction of the mounting groove 341 is embedded in the mounting groove 341. The setting of mounting groove 341 is favorable to reducing the height of connector 520 protrusion earphone main part, and it is more stable to connect to the groove lateral wall of mounting groove 341 can play spacing effect to connector 520, is favorable to avoiding that the limit structure on connector 520 and the connector 520 is crooked to width direction one side of mounting groove 341, and then avoids influencing locking piece 600 and limit structure's cooperation area, and influences locking piece 600 to limit structure's blocking effect. In some embodiments, the connector 520 may be completely embedded in the mounting groove 341, and a side surface of a side of the connector 520 away from the groove bottom wall of the mounting groove 341 and an opening edge of the mounting groove 341 are located on the same plane, so as to avoid that the connector 520 collides with other objects to affect structural stability.

In one embodiment, referring to fig. 4, the locking member 600 includes a blocking portion 610 and an inserting portion 620, the blocking portion 610 blocks the limiting protrusion 522 from moving toward the column-shaped main body 521, the inserting portion 620 is connected to the blocking portion 610, and the inserting portion 620 has an included angle with the blocking portion 610; the locking piece insertion cavity 330 is an insertion groove provided on the connection side 340, in which the insertion portion 620 is inserted. It should be understood that the term "stop" means a portion where the stopper 610 can block or stop the movement of the corresponding member, and can exert a limiting function. The provision of the blocking portion 610 is advantageous in increasing the mating area between the limiting structure on the connector 520 and the locking member 600, and has a better blocking effect.

The mating portion 620 of the locking element 600 may be perpendicular to the stop portion 610, which may facilitate installation of the locking element 600, as well as possibly removal. When the locking member 600 is mounted, the locking member 600 can be assembled to the earphone body by bringing the locking member 600 close to the locking member insertion cavity 330 on the earphone body in a direction perpendicular to the stopper 610. It will be appreciated that, when the locking member 600 is assembled, in order to better avoid the locking member 600 from being separated from the earphone body, an interference fit or a release preventing structure may be adopted between the locking member 600 and the earphone body. For example, the plugging portion 620 of the locking member 600 may be in interference fit with the cavity side wall of the plugging cavity 330 of the locking member, and the interference fit portion may be two side portions of the plugging portion 620 along the plugging direction of the interface plug 500, or may be two side portions of the plugging portion 620 along the width direction of the plugging groove; for another example, an adhesive structure, a clamping structure, a screw structure, etc. may be provided between the locking member 600 and the earphone body as the anti-falling structure; for another example, the plugging portion 620 of the locking element 600 may be inserted into the plugging cavity 330, after the connector 520 is pressed and fixed on the earphone body, an elastic coating is covered on the outer side of the whole earphone, and the elastic coating covers the locking element 600 and the connector 520, so that the locking element is more attractive, and the plugging portion 620 of the locking element 600 is prevented from being separated from the plugging cavity 330, so that the reliability of the electronic device is prevented from being influenced after the plugging portion 620 is separated from the plugging cavity 330. Of course, in some other embodiments, it is also possible to provide only the electronic control unit 300 with an elastic coating, as well as to prevent the locking member 600 from coming out.

With continued reference to fig. 3 and 4, and with additional reference to fig. 5, fig. 5 is an exploded view of the structure of the middle ear camera body and the interface plug 500 in fig. 3, in a specific embodiment, the plugging portion 620 is provided with two plugging portions 511 disposed at opposite ends of the blocking portion 610, and the corresponding two plugging grooves are respectively located at two sides of the mounting groove 341 in the groove width direction. The two plugging portions 620 are arranged, so that both ends of the blocking portion 610 are connected with the earphone body, the stress stability of the blocking portion 610 is better, and the connection with the earphone body is more reliable.

Referring to fig. 3, fig. 4, and fig. 5, it should be understood that in some embodiments, the locking member 600 may be in a sheet shape, and it should be noted that the sheet shape of the locking member 600 does not limit the locking member 600 to a planar structure, but means that the blocking portion 610 and the inserting portion 620 of the locking member 600 are both sheet bodies.

In other embodiments, the plugging portion 620 of the locking member 600 may be provided at only one place, for example, only one plugging portion 620 is provided at one side of the plugging groove in the width direction, and for example, one plugging portion 620 may be provided at one side of the connector 520 away from the plug body 510 on the earphone body.

In one embodiment, the locking element 600 includes an ear 630, the ear 630 being attached to the side of the stop 610 remote from the stop tab 522, the ear 630 covering at least a portion of the cylindrical body 521. The ear 630 provided on the locking member 600 can make the locking member 600 form a larger mating area with the side wall of the mounting groove 341, which is more advantageous for stable assembly of the locking member 600. In one embodiment, the ears 630 may also be omitted.

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, and as can be appreciated from a combination of fig. 6 and 7, the columnar body 521 may have an inner side surface facing the bottom wall of the mounting groove 341, an inner side protrusion 523 is provided on the inner side surface, an insertion groove 342 is provided on the bottom wall of the mounting groove 341, and the inner side protrusion 523 is inserted into the insertion groove 342. By the engagement of the insertion groove 342 with the inner protrusion 523, the insertion groove 342 can act as a stopper for the inner protrusion 523 on the connection body 520, and also can block the protrusion on the connection body 521 from moving in the direction of the columnar body 521, so that the connection body 520 can be more reliably prevented from coming off the earphone body. It should be noted that, the inner protrusion 523 provided on the side of the connector 520 near the earphone body may be a square protrusion as shown in the figure, or may be other shapes, such as a semicircle, a trapezoid, a triangle, a semi-ellipse, etc., where the shape refers to the cross-sectional shape of the inner protrusion 523, and the cross-section is perpendicular to the insertion and extraction direction of the interface plug 500. In addition, in a specific embodiment, the limiting protrusion 522 disposed on a side far from the earphone body may have other shapes, such as a semicircle, a trapezoid, a triangle, a semi-ellipse, etc.

The connection structure of the interface plug 500 and the earphone body may further refer to fig. 8 and 9. Fig. 8 is a schematic view of a section of fig. 3, the section being parallel to the plug direction of the plug 500 and passing through the center of symmetry of the plug 500, and fig. 9 is a schematic view of another section of fig. 3, the section being perpendicular to the plug direction of the plug 500 and passing through the locking member 600. As shown in fig. 8, in addition to the lock insertion cavity 330, the earphone body is further provided with a lock insertion groove 350, i.e., a groove into which the lock 600 is inserted to achieve the installation, and the lock 600 is inserted into the lock insertion groove 350. The provision of the locking piece insertion groove 350 can prevent the locking piece 600 from protruding out of the earphone body, and also can limit the locking piece 600, which is advantageous in reliably holding the locking piece 600 on the earphone body.

In one embodiment, the plug body 510 has a top surface remote from the connection port 360 with an uncapping protrusion 530 provided thereon, the uncapping protrusion 530 being located on a side of the plug body 510 remote from the connection body 520. By providing the lid opening protrusion 530, when a user needs to open the interface plug 500, the user can apply a force to the lid opening protrusion 530 obliquely toward the connection body 520 with a finger, and can operate conveniently.

In a specific embodiment, a recess 514 may be provided on the top surface of the plug body 510, the recess 514 being located on a side of the lid-opening protrusion 530 remote from the connecting body 520, and the projection of the recess 514 and the lid-opening protrusion 530 on the top surface in the pulling-out direction being continuous or partially coincident. It will be appreciated by those skilled in the art that the recess 514 allows the user's finger to extend into, thereby creating a larger area of interaction with the uncapping projections 530, and facilitating the force pulling out the interface plug 500 to tilt toward the side of the interface plug 500 where the connector 520 is located, thereby allowing easier opening of the interface plug 500.

As will be appreciated by those skilled in the art, since the interface plug 500 is inserted into the connection port 360, the greater the force in the direction of withdrawal of the interface plug 500, the more advantageous the smooth withdrawal of the interface plug 500. Accordingly, the uncapping protrusion 530 may be disposed obliquely, and the distance between the top of the uncapping protrusion 530 and the connection body is greater than the distance between the bottom of the uncapping protrusion 530 and the connection body, so that the user's finger can more easily apply a force to the interface plug 500 in the extraction direction of the interface plug 500.

The plugging operation of the interface plug 500 of the above-described earphone is described below.

When charging the headset, the interface plug 500 needs to be opened first. In operation, a user may place a finger on a side of the cap opening protrusion 530 away from the connector 520, and then apply a force to the cap opening protrusion 530, the direction of the force may be toward the connector 520, and a component force in the pull-out direction of the interface plug 500 may be formed as much as possible. Under the operation of a user, the plug body 510 of the interface plug 500 can be inclined and turned over to the side of the interface plug 500 where the connection body 520 is provided, and can be bent to a certain extent, and the connection body 520 can be stretched to a certain extent, and as the force and displacement increase, the plug body 510 finally comes out of the connection port 360, thereby exposing the connection port 360 for the insertion of the charging connector. Because of the limitation of the connector 520, the interface plug 500 is not completely separated from the earphone body, and the loss of the interface plug 500 can be avoided. In the above process, the blocking force direction of the locking member 600 on the connector 520 is perpendicular to the pulling direction of the interface plug 500, so that the interface plug 500 is not easy to separate from the earphone body, which is beneficial to the reliable fixing of the interface plug 500. When the interface plug 500 is inserted, the end of the interface plug 500 is aligned with the connection port 360, and then the connection port is pressed by a force.

In some related art, the connector 520 of the interface plug 500 is fixed to the earphone body by using adhesive after being assembled to the earphone body at a predetermined position, but the adhesion manner is very dependent on the reliability, heat resistance, aging degree, and the like of the adhesive, and is easy to fail in use. In the embodiment of the application, the force applied to the interface plug 500 is changed, and the locking piece 600 is used for fixing the interface plug 500, so that the force applied to the interface plug 500 when the interface plug 500 is opened at least partially avoids the pulling-out direction of the locking piece 600, and the interface plug 500 is difficult to fall off as long as the locking piece 600 is firmly fixed, thereby realizing more reliable fixing of the interface plug 500 by means of a mechanical structure.

Fig. 10 is a schematic structural diagram of an interface plug 500 in another embodiment of an earphone according to the present application, and it can be understood with reference to fig. 10 that the cooperation between the locking member 600 and the limiting structure on the connector 520 can be replaced by other forms. Referring to fig. 10 and 11, in one embodiment, the connector 520 is provided with a socket 710, the limiting structure is formed by the socket 710, the locking member 600 is a locking pin 720, and the locking pin 720 is inserted into the locking member socket 330 and the socket 710 at the same time, and the locking member socket may be a locking pin hole provided on the earphone body. The pins 720 may also be disposed at an angle to the direction of extraction of the plug 500, such as vertically. In this way, when the connector 520 receives a force in the pulling direction, the locking pin 720 only needs to bear a pulling force in the pulling direction, and the pulling force does not cause the locking pin 720 to be pulled out of the locking piece inserting cavity 330, so that the connection reliability of the interface plug 500 can be improved.

In a specific embodiment, the earphone body may be provided with a plugging channel 730, the axis of the plugging channel 730 is parallel to the pulling direction, the connector 520 is plugged into the plugging channel 730, and the sidewall of the plugging channel 730 is provided with a locking pin hole, and the locking pin hole forms the locking element plugging cavity 330. The insertion channel 730 can limit the displacement of the connector 520 along the axial direction of the locking pin 720, so that the locking pin 720 can be more effectively prevented from being separated, and the connection reliability of the interface plug 500 can be more effectively ensured. It will be understood by those skilled in the art that two opposite sidewalls of the insertion channel 730 may be provided with one locking pin hole, respectively, and both ends of the locking pin 720 may be inserted into the two locking pin holes, respectively, while the middle portion of the locking pin 720 is used to fix the connector 520 of the interface plug 500.
