Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by a person skilled in the art without any inventive effort, are intended to be within the scope of the present application based on the embodiments herein.

The embodiment of the application provides an earphone. The definition of the front, rear, upper and lower sides of the ear will be described first with reference to the wearing state.

Referring to fig. 1, fig. 1 is a schematic structural view of an ear. Wherein the text in fig. 1 shows part of the physiological position of the ear. The user's ear may include an helix, a navicular, an antitragus, a triangular fossa, a concha, an eardrum, a tragus, an earlobe, wherein the concha may include a concha boat and a concha cavity, and the eardrum may also be referred to as an external auricle or an opening to the external auditory canal. The front and back sides of the ear are defined as follows: the term "front side of an ear" as used herein refers to the concept of the front side of an ear relative to the back side of the ear, the front side of the ear facing away from the head, the back side of the ear facing toward the head, the upper edge of the ear referring to the rim of the ear on the side facing upward, the lower edge of the ear referring to the rim of the ear on the side facing downward, all for the user's ear.

The wearing state is defined as follows: the "wearing state" described herein, that is, a stable wearing state of the earphone after being stably worn on an ear of a human body (as shown in fig. 2 to fig. 4, fig. 2 is a first state diagram of the earphone provided in the embodiment of the present application when being worn on the ear, fig. 3 is a schematic diagram of another view angle of the structure shown in fig. 2, and fig. 4 is a second state diagram of the earphone provided in the embodiment of the present application when being worn on the ear), for example, as shown in fig. 2, the state of the earphone in fig. 2 may be understood as a first wearing state, where the sound emitting portion 12 of the earphone 10 does not cover the earhole area, or where the sound emitting portion 12 of the earphone 10 is not inserted into the earhole, and may also be understood as an open wearing mode of the earphone 10 in the first wearing state. As shown in fig. 4, the state of the earphone 10 in fig. 4 may be understood as a second wearing state, where the sound generating portion 12 of the earphone 10 is located closer to the ear hole than the sound generating portion 12 is located in the first wearing state, where the sound generating portion 12 may at least partially cover the ear hole area, or where the sound generating portion 12 of the earphone 10 may be partially inserted into the ear hole, or may be understood as an in-ear wearing mode of the earphone 10 in the second wearing state. Of course, due to individual differences among users, there may be some differences in the actual wearing state of the earphone 10 as compared to the aforementioned wearing state.

In the ear clip type earphone, the ear clip type earphone comprises a speaker cabin close to an ear canal of a wearer and a balance module arranged at the back of the ear, wherein the speaker cabin and the balance module are connected through an ear clip, and the ear clip provides a clamping force so that the speaker cabin and the balance module can be clamped and attached to the ear of the wearer.

Because the ear clip in the existing ear clip type earphone only provides the connecting force for connecting the loudspeaker cabin and the balance module and provides the clamping force for clamping ears, the ear clip itself cannot or hardly carries out accurate posture adjustment, so that the worn earphone is single relative to the posture of a wearer, such as the existing ear clip type earphone can only provide an open wearing mode, and the ear clip type earphone is used as an open earphone, namely the loudspeaker cabin can only be positioned outside an earhole and can not be used as an in-ear earphone, the wearing posture of the earphone cannot be changed according to the needs of a user to realize different wearing modes, and the experience is poor.

Based on this, the embodiment of the application provides an earphone to solve the problem that the earphone wears the gesture singleness.

Referring to fig. 5 and fig. 6 in combination with fig. 2 to fig. 4, fig. 5 is a first schematic structural diagram of an earphone according to an embodiment of the present application, and fig. 6 is a schematic structural diagram of the earphone in another state shown in fig. 5. It will be appreciated that the adjustment member 14 shown in fig. 5 and 6 is generally embedded within the ear clip portion 13 and is not visible, which is illustrated as being externally visible for ease of description, such as by removing a portion of the material that encases the adjustment member 14.

The earphone 10 may include a balance portion 11, a sound emitting portion 12, an ear clip portion 13, and an adjustment member 14. Wherein the sound generating part 12 is provided with a speaker (not shown), it will be appreciated that in order to facilitate sound generation, the sound generating part 12 may be provided with at least one sound generating hole (not shown), which is acoustically coupled to the speaker, such that when the sound generating part 12 is located at the front side of the ear, sound may be propagated to the ear hole of the ear through the sound generating hole, so that a user can hear corresponding sound information.

One end of the ear clip portion 13 is connected to the sounding portion 12, and the other end of the ear clip portion 13 is bent and extended toward the balance portion 11 and connected to the balance portion 11, wherein the ear clip portion 13 can provide a certain clamping force. It will be appreciated that when the earphone 10 is worn on the ear, the balance portion 11 is located at the rear side of the ear, the sounding portion 12 is located at the front side of the ear, and the ear clip portion 13 extends from the rear side of the ear to the front side of the ear via the helix of the ear, so that the balance portion 11 and the sounding portion 12 can clip the ear under the clamping force of the ear clip portion 13.

An adjusting member 14 is provided in the ear clip portion 13, the adjusting member 14 being for adjusting a bending state of the ear clip portion 13 to enable the earphone 10 to be switched between a first wearing state and a second wearing state. In the first wearing state, the balance portion 11 is located at the rear side of the ear, the sound emitting portion 12 is located at the front side of the ear, and the sound emitting portion 12 is located outside the earhole, and the balance portion 11 and the sound emitting portion 12 clamp the ear by the adjusting member 14 and the ear clamp portion 13, as shown in fig. 2 and 3.

As shown in fig. 4, in the second wearing state, the sound emitting portion 12 is positioned closer to the earhole than the sound emitting portion 12 is positioned in the first wearing state, and the sound emitting portion 12 can cover at least a part of the earhole area. Since there is a difference in ear configuration of different users, there is a difference in adjustment of the ear clip portion 13 by the adjustment member 14 in the second wearing state, but after the adjustment is completed, the sound emitting portion 12 can cover at least a part of the earhole region in the second wearing state.

It can be appreciated that, in the earphone 10 provided by the present application, the adjusting member 14 is disposed on the ear clip portion 13 of the earphone 10, so that the bending state of the ear clip portion 13 can be adjusted, and thus, the relative distance between the balance portion 11 and the sounding portion 12 can be changed, so that the earphone 10 can be switched between the first wearing state and the second wearing state. In the first wearing state, the balance portion 11 is located at the rear side of the ear, the sound emitting portion 12 is located at the front side of the ear, and the sound emitting portion 12 is located outside the earhole, and the ear is clamped by the balance portion 11 and the sound emitting portion 12, so that the earphone 10 can be used as the open earphone 10. In the second wearing state, the sound emitting portion 12 is positioned closer to the earhole than the sound emitting portion 12 is in the first wearing state, such as the sound emitting portion 12 covering at least a part of the earhole area, at which time the earphone 10 can be used as an in-ear earphone 10. In this way, under the action of the adjusting member 14, the earphone 10 can have at least two different wearing postures, so that the wearing posture of the earphone 10 can be effectively changed according to the needs of the user, and the use experience of the user is improved.

It will also be appreciated that the headset 10 may also include a motherboard and a battery. The main board is mainly used for controlling sound production of the speaker or realizing other control functions or information processing functions, and the battery is mainly used for providing electric energy for the main board of the earphone 10 or the speaker or other electronic components in the earphone 10 needing electricity. Of course, the earphone 10 described herein may further include a microphone such as a microphone and a pickup, and may further include communication devices such as bluetooth and NFC (Near Field Communication ), which are electrically connected to the main board and the battery through corresponding conductors, so as to implement corresponding functions.

As an example, a speaker may be mounted on the sound emitting portion 12, and the sound emitting portion 12 can be pressed against the user's ear by a pressing force when the earphone 10 is in a wearing state. Further, when the earphone 10 is in the wearing state, since the sound emitting portion 12 is mainly located at the front side of the ear of the user, in order to enable the earphone 10 to be better clamped to the ear, the balancing portion 11 is used as a component for balancing the weight of the earphone 10, and the balancing portion 11 is located at the rear side of the ear, so that the balancing portion 11 and the sound emitting portion 12 can cooperate together to achieve the effect of balancing the weight. In order to reasonably utilize the space, based on this, one of the main board, the battery and the bluetooth module may be disposed at the sound generating portion 12, and the other two may be disposed at the balance portion 11, or both may be disposed at the sound generating portion 12, and the other one may be disposed at the balance portion 11, or all three may be disposed at the sound generating portion 12, or all three may be disposed at the balance portion 11. For example, a main board may be provided at the sound emitting portion 12, and a battery and a bluetooth module may be provided at the balance portion 11.

Of course, it is easy to know by those skilled in the art that the above-mentioned distribution of electronic components between the sounding part 12 and the balance part 11 is merely an example, and those skilled in the art can change the structural members in the sounding part 12 and the structural members in the balance part 11 according to design requirements, and the adjustment of the structural members at different positions is included in the technical solution of the present application, and the weight ratio is not affected, which is not repeated here. At this time, the weight of the earphone 10 may be distributed at two ends relatively uniformly, so that the earphone 10 at least can not slide down in the non-moving state when in the wearing state.

Of course, it will also be appreciated that the user's ears may bear most of the weight of the headset 10 while wearing the headset 10, which may be prone to discomfort in a long wearing scenario. For this purpose, the balance portion 11, the sound generating portion 12, the ear clip portion 13, and the like may be made of soft materials (such as polycarbonate, polyamide, acrylonitrile-butadiene-styrene copolymer, silica gel, leather, fabric, etc.) so as to improve the comfort of the earphone 10 in wearing.

It will also be appreciated that since the balance portion 11 and the sound emitting portion 12 need to be provided with various electronic components, the balance portion 11 and the sound emitting portion 12 may be made of a material having a relatively hard texture, such as a hard plastic product, and of course, for the comfort of wearing, at least the areas of the balance portion 11 and the sound emitting portion 12 in contact with the skin of the user may be provided with an elastic coating layer such as a material having a relatively soft texture (e.g., polycarbonate, polyamide, acrylonitrile-butadiene-styrene copolymer, silica gel, leather, fabric, etc.), or may be coated with an elastic paint.

Further, in order to improve the structural strength of the earphone 10, a supporting structure (not shown), such as an elastic wire of spring steel, titanium alloy, titanium-nickel alloy, chrome-molybdenum steel, aluminum alloy, copper alloy, or the like, may be provided in the ear clip portion 13. It will be appreciated that the length of the support structure may be at least one fifth of the length of the ear clip portion 13, i.e. the support structure may be provided in a small section of the ear clip portion 13, or the support structure may be provided in the entire section of the ear clip portion 13.

It should be noted that in the description of the present application, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implying a number of technical features which is being indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more features.

It will be appreciated that, for ease of wearing the earphone 10, with continued reference to fig. 5 and 6, the ear clip portion 13 is arc-shaped, and the ear clip portion 13 includes a first connecting section 131 and a second connecting section 132 connected to each other, the first connecting section 131 is connected to the sounding portion 12, and the second connecting section 132 is connected to the balance portion 11. That is, one end of the first connecting section 131 is connected to the sound emitting portion 12, the other end of the first connecting section 131 is connected to the second connecting section 132, and one end of the second connecting section 132 remote from the first connecting section 131 is connected to the balance portion 11.

The connection between the first connection section 131 and the sounding part 12 may be fixed connection or rotational connection, and it may be understood that when the first connection section 131 is rotationally connected with the sounding part 12, the sounding part 12 may be adjusted by a certain angle relative to the first connection section 131, so that the sounding part 12 may be better attached to the ear.

Similarly, it is understood that the connection between the second connecting section 132 and the balance portion 11 may be a fixed connection or a rotational connection, and it is understood that when the second connecting section 132 is rotationally connected to the balance portion 11, the balance portion 11 may be adjusted by a certain angle with respect to the second connecting section 132, so that the balance portion 11 may better fit to the ear.

In the embodiment of the present application, in the first wearing state, the balance portion 11 is located at the rear side of the ear, the sounding portion 12 is located at the front side of the ear and the sounding portion 12 is located outside the earhole, and the balance portion 11 and the sounding portion 12 sandwich the ear. In the second wearing state, the sound emitting portion 12 is positioned closer to the earhole than the sound emitting portion 12 is in the first wearing state, and the sound emitting portion 12 covers at least a part of the earhole area. It will be appreciated that in the first wearing state and in the second wearing state, the bending state of the ear clip portion 13 is different, i.e. the bending state of the ear clip portion 13 needs to be changed to enable the earphone 10 to switch between the first wearing state and the second wearing state. Wherein, in order to facilitate changing the positional relationship between the sound emitting portion 12 with respect to the balance portion 11, an adjusting member 14 may be provided at least at the first connection section 131 for adjusting the bending state of the first connection section 131 so that the earphone 10 can be switched between the first wearing state and the second wearing state.

Wherein, when the first connection section 131 is adjusted by the adjusting member 14, it can take on different bending states, and when the bending states of the first connection section 131 are different, the relative position between the sound emitting portion 12 and the balance portion 11 is also changed, so that the earphone 10 can be switched between the first wearing state and the second wearing state. For example, in the first wearing state, the sound emitting portion 12 is located on the front side of the ear portion and the sound emitting portion 12 is located outside the earhole, and when the bending state of the first connecting section 131 is adjusted by the adjusting member 14, the earphone 10 can be switched from the first wearing state to the second wearing state, and the position of the sound emitting portion 12 can be made closer to the earhole than the position of the sound emitting portion 12 in the first wearing state, at which time the sound emitting portion 12 covers at least a part of the earhole region.

Referring specifically to fig. 2 and 4 in conjunction with fig. 1, in the first wearing state and the second wearing state, the earphone 10 is located approximately in the middle of the ear, or alternatively, the earphone 10 may be located approximately in a position in which the middle of the ear is located upward or in which the middle of the ear is located downward.

It will be appreciated that as shown in fig. 1, the ear includes an upper ear edge and a lower ear edge, and that the middle of the ear may be understood as a portion between the upper ear edge and the lower ear edge approximately in the middle of the ear, such as the portion of the concha cavity.

It will also be appreciated that since in the second wearing state the sound emitting portion 12 needs to be moved to at least partially cover the earhole area, at this time, if the length of the first connecting section 131 after the bending state is changed is insufficient for the sound emitting portion 12 to extend into the earhole area, it is necessary to slightly adjust the position of the balance portion 11, such as the balance portion 11 may be adjusted in the direction of the front side of the ear so that the sound emitting portion 12 can be moved to at least partially cover the earhole area, at which time the balance portion 11 may be at least partially in contact with the helix. Of course, due to the difference of the individual ears, if the length of the first connecting section 131 after the bending state is changed is enough for the sound emitting portion 12 to protrude into the earhole region, it is not necessary to adjust the balance portion 11 toward the front side of the ear, and at this time, the balance portion 11 is still located at the rear side of the ear.

It will also be appreciated that in the first wearing state, the earphone 10 may be held by the holding force such that the balance 11 and the sounding 12 clamp the ear. The clamping force may be provided by the ear clip portion 13 alone, or may be provided by the ear clip portion 13 and the adjustment member 14 together, which is not limited herein.

In the second wearing state, the earphone 10 can be attached to the ear by the clamping force, and the sound emitting portion 12 can be at least partially inserted into the earhole, that is, the earhole can generate a certain supporting force for the sound emitting portion 12, at this time, the earphone 10 can be stably worn on the ear under the combined action of the clamping force and the supporting force.

In order to enable the earphone 10 to be worn on the ear more stably, referring to fig. 1, 2 and 5, the sound generating portion 12 includes a first abutment surface 121 facing to a side of the concha cavity, and in the first wearing state, the first abutment surface 121 is at least partially abutted to the concha cavity.

The sound generating portion 12 may further include an insertion section 122 and a fixing section 123 that are connected to each other, where the fixing section 123 is connected to the ear clip portion 13, such as the fixing section 123 is connected to the first connecting section 131 of the ear clip portion 13, and an end of the insertion section 122 near the ear hole is provided with a sound outlet hole, and in the second wearing state, the insertion section 122 is at least partially inserted into the ear hole.

The sound outlet hole can be arranged on one side of the insertion section 122 facing the ear hole, so that sound can be better conducted into the ear hole, and the sound transmission quality is improved.

In some embodiments, to further improve the wearing stability of the earphone 10, in the first wearing state, the sound emitting portion 12 and the balance portion 11 are clamped to the ear, and the orthographic projections of the sound emitting portion 12 and the balance portion 11 on the ear at least partially overlap. In this way, the sounding part 12 and the balance part 11 can be substantially opposed to each other on the front and rear sides of the ear, thereby making the clamping effect better.

It will be appreciated that in both the first and second worn conditions, the second connecting section 132 is more or less capable of providing a clamping force, and therefore the absolute value of the first average radius of curvature of the first connecting section 131 is greater than the absolute value of the second average radius of curvature of the second connecting section 132. In this way, the second connecting section 132 is bent to a greater extent than the first connecting section 131, and therefore, the second connecting section 132 can provide sufficient clamping force in both wearing states to enable the earphone 10 to be worn more stably.

It will also be appreciated that, as shown in fig. 2 and 4, in the first wearing state, the first connecting section 131 is bent to form a curved first curved shape 131a facing the ear, and the bending degree of the first connecting section 131 may be gradually adjusted to be more gentle or reverse during the process of switching the earphone 10 from the first wearing state to the second wearing state, so that the sounding part 12 can be moved to cover at least a part of the earhole area, such as when being adjusted to the second wearing state, the first connecting section 131 is adjusted to a second curved shape 131b curved opposite to the ear, that is, the opening formed by the first curved shape 131a is oriented opposite to the opening formed by the second curved shape 131 b.

It should be understood that, in the second wearing state, the opening formed by bending the first connecting section 131 may not be opposite to the opening formed by bending the first connecting section 131 in the first wearing state, so long as the sounding part 12 can move to at least cover a part of the earhole region.

Specifically, please refer to fig. 5 and 6, the following definitions are now made for each outer surface of the ear clip portion 13: the surface of the ear clip portion 13 on the side facing the ear of the user is defined as the inner surface. The surface of the ear clip portion 13 on the side facing away from the user's ear is defined as the outer surface. It is understood that the first connecting segment 131 of the ear clip portion 13 includes a first outer surface 1312 facing away from the ear and the second connecting segment 132 includes a second outer surface 1322 facing away from the ear, wherein an absolute value of a first average radius of curvature of the first connecting segment 131 is greater than an absolute value of a second average radius of curvature of the second connecting segment 132. It is understood that an absolute value of the first average radius of curvature of the first outer surface 1312 is greater than an absolute value of the second average radius of curvature of the second outer surface 1322.

It should be noted that, in the direction from the end connected to the second connecting section 132 toward the end connected to the sound generating portion 12, the radius of curvature of each point of the first connecting section 131 may be gradually changed, such as gradually decreased, or gradually increased, then gradually decreased, or first gradually decreased, then gradually increased. Based on this, for ease of understanding, the first average radius of curvature is used in embodiments of the present application to characterize the radius of curvature of the first connecting segment 131.

Similarly, the radius of curvature of each point of the second connecting section 132 may be gradually changed, such as gradually decreased, or gradually increased and then gradually decreased, or gradually decreased and then gradually increased, in a direction from the end connected with the first connecting section 131 toward the end connected with the balance 11. Based on this, for ease of understanding, the second average radius of curvature is used in embodiments of the present application to characterize the radius of curvature of the second connecting section 132.

Illustratively, in the first wearing state, the absolute value of the first average radius of curvature ranges from 10 millimeters to 40 millimeters and the absolute value of the second average radius of curvature ranges from 3 millimeters to 10 millimeters. Specifically, in the first wearing state, the absolute value of the first average radius of curvature of the first outer surface 1312 of the first connecting segment 131 ranges from 10 mm to 40 mm, such as any value between 10 mm and 40 mm, including 10 mm and 40 mm. The absolute value of the second average radius of curvature of the second outer surface 1322 of the second connecting segment 132 ranges from any value between 3 millimeters and 10 millimeters, such as between 3 millimeters and 10 millimeters, including 3 millimeters and 10 millimeters. The application is not limited herein. In this way, the earphone 10 can be stably worn on the ear of the user with the average radius of curvature.

In the second wearing state, the absolute value of the first average curvature radius ranges from 10 mm to 40 mm, and the absolute value of the second average curvature radius ranges from 3 mm to 10 mm. Specifically, in the second wearing state, the absolute value of the first average curvature of the first outer surface 1312 of the first connecting section 131 ranges from 10 mm to 40 mm, such as any value between 10 mm and 40 mm, including 10 mm and 40 mm. The absolute value of the second average radius of curvature of the second outer surface 1322 of the second connecting segment 132 ranges from 3 millimeters to 10 millimeters, such as any number between 3 millimeters and 10 millimeters, including 3 millimeters and 10 millimeters. The application is not limited herein. As described above, with this average radius of curvature, the sound emitting portion 12 of the earphone 10 can be stably inserted into the earhole, and the earphone 10 can be stably worn on the ear of the user.

In the first wearing state, in a direction from the end of the balancing portion 11 near the ear portion to the end far from the ear portion, the thickness of the balancing portion 11 is positively correlated with the absolute value of the second average radius of curvature of the second connecting section 132. That is, in the first wearing state, the greater the thickness of the balance portion 11, the smaller the degree of bending of the second connecting section 132 in the direction in which the end of the balance portion 11 near the ear portion faces away from the ear portion end. Thus, when the earphone 10 is worn on the ear of the user, too much pressure is not applied to the ear, and wearing comfort is improved.

The overall configuration of the earphone 10 is described above, and the specific structure of the adjusting member 14 and the components related thereto will be described below with reference to the drawings.

It is understood that the adjusting member 14 is used as a structural member for adjusting the bending state of the ear clip portion 13, and may be disposed in the ear clip portion 13, for example, the ear clip portion 13 is made of soft material, and the adjusting member 14 is wrapped in the ear clip portion 13 through an injection molding process.

It will also be appreciated that when the earphone 10 is switched between the first wearing state and the second wearing state, the bending state of the ear clip portion 13 as a whole does not need to be adjusted, and the earphone 10 can be switched between the first wearing state and the second wearing state by adjusting only a part of the ear clip portion 13, so the length of the adjusting member 14 may be set to be at least one fifth of the length of the ear clip portion 13, so that the earphone 10 can be switched between the first wearing state and the second wearing state. For example, the length of the adjustment member 14 may be one fifth, one fourth, one third, one half, or the same as the length of the ear clip portion 13. The application is not limited herein.

It is further understood that, as shown in fig. 5 and 6, the ear clip portion 13 includes a first connecting section 131 and a second connecting section 132 connected to each other, the first connecting section 131 being connected to the sound emitting portion 12, and the second connecting section 132 being connected to the balance portion 11. The adjusting member 14 is provided at least at the first connecting section 131 for adjusting a bending state of the first connecting section 131 to enable the earphone 10 to be switched between the first wearing state and the second wearing state.

In some embodiments, referring to fig. 5 and 6, the adjusting member 14 includes at least one hinge set 141, where the hinge set 141 includes at least two hinges 1411, and the at least two hinges 1411 are sequentially hinged along the bending direction of the ear clip portion 13, and when the angle between two adjacent hinges 1411 is adjusted, the bending state of the ear clip portion 13 can be adjusted, and the ear clip portion 13 is maintained in the adjusted bending state. In this way, by adjusting the angle between two adjacent hinges 1411 in the hinge group 141, the bending state of the ear clip portion 13 can be adjusted and the ear clip portion 13 is maintained in the adjusted bending state, so that the earphone 10 can be switched between the first wearing state and the second wearing state according to the need.

It is understood that the adjustment member 14 may comprise only one set of hinges 141, as shown in fig. 5 and 6, and that one set of hinges 141 may be located only in the first connection section 131. Fig. 7 is a schematic diagram of a second structure of the earphone according to the embodiment of the present application, and fig. 8 is a schematic diagram of the earphone shown in fig. 7 in another state. It will be appreciated that the hinge assembly 141 shown in fig. 7 and 8 is generally embedded within the ear clip portion 13 and is not visible, as such, for ease of description, it is shown as being visibly apparent, such as by removing a portion of the material that encases the hinge assembly 141. A set of hinges 141 may also be located at the first connection section 131 and at least a portion of the hinges 1411 extend to the second connection section 132. It will be further appreciated that the specific configuration of the hinge in fig. 7 and 8 is merely illustrative, and the number of hinges 1411 in the hinge in fig. 7 and 8 is three, however, the number of hinges 1411 in fig. 7 and 8 may be two, so long as the hinge 1411 is sufficiently sized to allow at least a portion of the hinge 1411 to extend to the second connecting portion 132.

It is further understood that the adjusting member 14 may also include multiple sets of hinge sets 141, such as two or more sets of hinge sets 141, where all of the hinge sets 141 may be located in the first connecting section 131, some of the hinge sets 141 may be located in the first connecting section 131, and other of the hinge sets 141 may be located in the second connecting section 132, which is not limited herein.

The included angle between two adjacent hinges 1411 in the hinge group 141 can be adjusted from 90 degrees to any value between 270 degrees. As shown in fig. 9, fig. 9 is a schematic view illustrating a rotation state of the hinge assembly according to the embodiment of the present application. The included angle between two adjacent hinges 1411 can be adjusted from the included angle α1 to α2, and it can be appreciated that the dashed line in fig. 9 represents another state of the hinge 1411 after adjusting the corresponding angle.

To facilitate articulation between the hinges 1411, referring to fig. 6, one of the hinges 141, such as the first hinge 1411a, is provided with a first articulation 14111 and the adjacent hinge, such as the second hinge 1411b, is provided with a second articulation 14112, the first articulation 14111 and the second articulation 14112 being articulated by a first pivot 1412.

For example, with continued reference to fig. 6, the hinge 1411 may include two hinges, namely a first hinge 1411a and a second hinge 1411b, the first hinge 1411a being provided with a first hinge portion 14111, the second hinge 1411b being provided with a second hinge portion 14112, the first hinge portion 14111 and the second hinge portion 14112 being hinged by a first pivot 1412.

For example, referring to fig. 7 and 8, the hinge 1411 may include three hinges, namely, a first hinge 1411a, a second hinge 1411b, and a third hinge 1411c, wherein the second hinge 1411b is located between the first hinge 1411a and the second hinge 1411c, and it is understood that one end of the second hinge 1411b is hinged to the first hinge 1411a and the other end of the second hinge 1411b is hinged to the third hinge 1411 c.

Fig. 10 is a schematic diagram of a third structure of the earphone according to the embodiment of the present application, and fig. 11 is a schematic diagram of the structure of the earphone in another state shown in fig. 10. It will be appreciated that the hinge assembly 141 shown in fig. 10 and 11 is generally embedded within the ear clip portion 13 and is not visible, which is illustrated as being externally visible for ease of description, such as by removing a portion of the material that encases the hinge assembly 141. The hinges 1411 may include four hinges 1411 that in turn hinge to form the hinge group 141.

It will be appreciated that the number of hinges 1411 may be set according to the actual situation, and the present application is not limited herein.

In some embodiments, referring to fig. 12, fig. 12 is a schematic view of a first structure of a hinge assembly according to an embodiment of the present application. In order to make the hinge 1411 more stable when rotated, the first hinge portion 14111 of one hinge 1411 includes a first sub-portion 14111a and a second sub-portion 14111b disposed at intervals in an axial direction, and the second hinge portion 14112 of the hinge 1411 adjacent thereto is disposed between the first sub-portion 14111a and the second sub-portion 14111b and hinged by the first shaft 1412.

In some embodiments, a first damping layer may be sandwiched between first shaft 1412 and first hinge 14111. Or a second damping layer may be sandwiched between the first shaft 1412 and the second hinge 14112. Damping layers may be provided between the first shaft 1412 and the first hinge 14111 and between the first shaft 1412 and the second hinge 14112. In this way, it is ensured that the hinge 1411, when rotated, can stay at any angle through which it rotates and that the earphone 10 can remain in an adjusted state. In addition, this arrangement allows for a stepless or continuous adjustment of the angle, i.e., the hinge 1411 can stay anywhere between a minimum angle and a maximum angle within a range of motion, without a predetermined gear, and the rotation of the hinge 1411 is continuous, variable, not jumping, and is an arbitrary relatively smooth adjustment within a range. In this way, the position adjustment precision of the hinge 1411 can be higher, and users with different ear sizes can be better adapted.

In order to enable the hinge 1411 to rotate within a certain rotation range, the hinge group 141 may further include a limiting structure 1413, where the limiting structure 1413 is used to limit a maximum rotation angle between the adjacent hinges 1411.

In some embodiments, referring to fig. 13, fig. 13 is a schematic view of a second structure of a hinge assembly according to an embodiment of the present application. The spacing structure 1413 is disposed between adjacent hinges 1411.

Illustratively, the spacing structure 1413 includes a first spacing tab 14131 and a first spacing slot 14132, the first spacing tab 14131 being disposed in one of the hinges 1411, the first spacing slot 14132 being disposed in the adjacent other hinge 1411, the first spacing tab 14131 cooperating with the first spacing slot 14132 to limit a maximum angle of rotation between the adjacent hinges 1411.

Specifically, the first limiting groove 14132 is disposed on the first hinge portion 14111 of one of the hinges 1411, and the first limiting protrusion 14131 is disposed on the adjacent hinge 1411 and extends into the first limiting groove 14132, and when the hinge 1411 rotates to a certain angle, the first limiting protrusion 14131 can abut against the groove wall of the first limiting groove 14132, so as to limit the rotation angle between the adjacent hinges 1411.

In other embodiments, referring to fig. 14, fig. 14 is a schematic view of a third structure of a hinge assembly according to an embodiment of the present application. The limiting structure 1413 is disposed between the first shaft 1412 and a first hinge 14111 that mates with the first shaft 1412.

Illustratively, the limiting structure 1413 includes a second limiting protrusion 14133 and a second limiting groove 14134, the second limiting protrusion 14133 is disposed on the first shaft 1412, the second limiting groove 14134 is disposed on the first hinge portion 14111 that mates with the first shaft 1412, the second limiting protrusion 14133 extends into the second limiting groove 14134, and the second limiting protrusion 14133 mates with the second limiting groove 14134 to limit the maximum angle of rotation between adjacent hinges 1411. It will be appreciated that when the hinge 1411 is rotated to a certain angle, the second limiting protrusion 14133 may abut against the groove wall of the second limiting groove 14134, so as to limit the rotation angle between the adjacent hinges 1411.

It will be appreciated that because the adjustment member 14 can be wrapped in the ear clip portion 13 by an injection molding process, based on this, in order to make the adjustment member 14 more tightly bondable to the ear clip portion 13, a hole 14113 can be provided on the adjustment member 14, such as a hole 14113 can be provided on the hinge 1411, so that when the hinge 1411 is wrapped in the ear clip portion 13 by an injection molding process, molding material can partially flow into the hole 14113, thereby improving the bonding tightness between the ear clip portion 13 and the hinge 1411. At the same time, the weight of the adjusting member 14 can be reduced, so that the overall weight of the ear clip portion 13 is lighter. The hole 14113 may be a through hole or a blind hole, which is not limited herein.

It should be noted that, the hinge and the ear clip portion 13 have a certain thickness, if the thickness of the hinge is too thick, the thickness of the ear clip portion 13 is too thin, the hinge can deform the appearance of the ear clip portion 13, which affects the appearance of the ear clip portion 13, and if the thickness of the hinge is too thin, the thickness of the ear clip portion 13 is too thick, which can cause the situation that the bending degree of the ear clip portion 13 cannot be adjusted or the adjusting effect is not good through the hinge. Based on this, in some embodiments, the ratio between the maximum thickness of the hinge and the maximum thickness of the ear clip portion 13 may be set between 0.3 and 0.7, such as the maximum thickness of the hinge being the thickness at the axis of rotation, which may range between 1.5 mm and 3 mm, including any value between 1.5 mm and 3 mm and 1.5 mm and 3 mm. The thickness of the ear clip portion 13 can range from about 2.5 mm to about 5 mm, including any number between about 2.5 mm and about 5 mm and between about 2.5 mm and about 5 mm. The thickness of the hinge is smaller than the thickness of the ear clip portion 13, wherein the thickness of the ear clip portion 13 includes the thickness of the wrapping layer of the ear clip portion and the hinge or the like included therein, i.e., the thickness of the whole represents the thickness of the ear clip portion 13. Thus, the arrangement of the thickness does not affect the appearance of the ear clip portion 13 or the effect of adjusting the degree of bending of the ear clip portion 13.

In order to better adjust the bending state of the second connecting section of the ear clip portion, in some embodiments, refer to fig. 15, and fig. 15 is a schematic structural diagram of the deformation element provided in the embodiment of the present application when the deformation element is mounted on the second connecting section. It will be appreciated that the deformation member 142 shown in fig. 15 is generally embedded within the second connecting section 132 and is not visible, and is illustrated as being visibly apparent for ease of description, such as by removing a portion of the material that encases the deformation member 142. The adjusting member 14 may further include a deforming member 142, where the deforming member 142 is disposed on the second connecting section 132, and the deforming member 142 is used to adjust the bending state of the second connecting section 132. The deforming member 142 may be a hinge structure, a spring structure, a metal sheet or a metal wire, etc. capable of deforming, so as to adjust the bending state of the second connecting section 132. In this embodiment, the deformation member 142 adopts a spring structure.

Referring to fig. 16 and 17, fig. 16 is a schematic view of a first state of the deforming member in fig. 15, and fig. 17 is a schematic view of a second state of the deforming member in fig. 15. In the first wearing state, the deforming member 142 is bent to face the ear to form a first curved shape 1421 in an arc shape, and in the second wearing state, the deforming member 142 is bent to face away from the ear to form a second curved shape 1422 in an arc shape, and the direction of an opening formed by the first curved shape 1421 is opposite to the direction of an opening formed by the second curved shape 1422. In this way, the bending state of the second connecting section 132 can be changed by the deforming member 142, so as to better adapt to the adjustment requirement of the user.

It is understood that the first and second curved shapes 1421 and 1422 may be the same or different.

The above-mentioned so-called "the first bent shape and the second bent shape of the deforming member 142 may be the same" may be understood as: the deforming members 142 have the same or symmetrical shape and the same geometric dimensions (e.g., length, width, chord cut angle, average radius of curvature, etc.) although they have different bending directions. Note that the same references mentioned in the embodiments of the present application refer to: identical or substantially identical. For example, referring to fig. 16 and 17, the deforming member 142 is bent in opposite directions to form an arc shape with opposite opening directions. In other words, in the embodiment shown in fig. 16 and 17, the first and second folded shapes are each arc-shaped, and the length, width, chord cut angle, average radius of curvature, etc. thereof are all substantially the same, so that they are substantially the same or symmetrical. However, the first bending shape and the second bending shape are not limited to an arc shape, and the arc shape is only a special curve shape, and may be other geometric curves, free curves, or a combination of curves and straight lines, etc. that can realize at least two identical bending shapes.

The above-mentioned so-called "the first bent shape and the second bent shape of the deforming member 142 may be different" may be understood as: the deformation members 142 may have different or slightly different shapes after bending, or at least one of different or slightly different geometric dimensions (e.g., length, width, chord cut angle, average radius of curvature, etc.). Illustrating several cases where the "first and second folded shapes may be different": both profiles are generally arcuate with different average radii of curvature, or both profiles are significantly different curvilinear shapes with the same or different average radii of curvature. Likewise, the first and second folded shapes herein may be geometric curves, free curves, or a combination of curves and straight lines, etc. that enable at least two different folded shapes.

In practice, the so-called different directions cannot be limited only to the opposite directions, and the plurality of bent shapes cannot be limited only to the first bent shape shown in fig. 16 and the second bent shape shown in fig. 17. In other embodiments, the deforming member 142 may be configured to bend at other angles, thereby being capable of being bent into more bent shapes, further providing more use configurations for the ear clip. Therefore, the deformation member 142 provided in the embodiment of the present application may be a flexible sheet, and can be freely designed to form different shapes after being deformed according to different bending modes or deformation modes, so as to provide more use postures.

Referring to fig. 18, fig. 18 is a projection view of the deformation element on a side projection plane. The surface of the deforming member 142 is configured as an arc surface, the arc surface is projected as an arc line 1423 on the side projection surface, and the chord angle β of the arc line 1423 is 15 degrees to 45 degrees. It is understood that the arc line 1423 includes a first end portion 14231 and a second end portion 14232, the first line portion 1424 connects the first end portion 14231 and the second end portion 14232, the second end portion 14232 is a tangent line 1425 of the arc line 1423, the arc line 1423 is located in an included angle area formed by the first line portion 1424 and the tangent line 1425, and the chord angle β is an included angle formed by the first line portion 1424 and the tangent line 1425. As the chord angle β of the arc changes in magnitude, the degree of curvature of the arc 1423 also changes. It will also be appreciated that the chord cut angle may be the same (or may be substantially the same) or may be different (e.g., slightly different or more different) in the first and second wear states.

The "arc" may be an inner arc formed on the side projection surface of the deformable member 142 or an outer arc formed on the side projection surface of the deformable member 142. In general, the projection of the deformation member 142 on the side projection surface does form an inner arc and an outer arc, but since the deformation member 142 provided in the embodiment of the present application is a sheet, the inner arc and the outer arc have substantially the same chord tangent angle, the inner arc and the outer arc need not be distinguished herein, and are collectively referred to as "arcs" as the two. In other embodiments, however, if the deforming member 142 is not a sheet and is thick enough to cause the chord cut angles of the inner and outer arcs to differ, the chord cut angle β (15 degrees to 45 degrees) of the arc 1423 may be referred to as the chord cut angle of the outer arc.

Specifically, the deforming member 142 is a flexible sheet, and the deforming member 142 includes a first flexible arm 14261, a second flexible arm 14262, a first connecting portion 1427, a second connecting portion 1428, and an opening 1429. First flexible arm 14261 and second flexible arm 14262 are spaced around aperture 1429. When the deforming member 142 is disposed on the second connecting section 132, the length direction of the deforming member 142 and the length direction of the second connecting section 132 are substantially identical, and the width direction of the deforming member 142 and the width direction of the second connecting section 132 are substantially identical. The first flexible arms 14261 and the second flexible arms 14262 of the deforming member 142 are arranged and spaced apart along the width direction of the deforming member 142. The openings 1429 may reduce the weight, and may also disperse the force, so as to prevent the deformation element 142 from being undesirably reversed, for example, to prevent the deformation element 142 from being reversely bent when being touched by a little accident.

The first connection portion 1427 fixedly connects one ends of the first flexible arm 14261 and the second flexible arm 14262. The term "fixed connection" is used with respect to the term "movable connection". The fixed connection in the embodiment of the present application refers to a one-piece structure, for example: the first connection 1427 is a one-piece structure with the first flexible arm 14261 and the second flexible arm 14262, rather than a two-piece structure connected together. In other embodiments, the fixed connection may also be another way of connection, such as by welding.

The second connecting portion 1428 movably connects the other ends of the first flexible arm 14261 and the second flexible arm 14262 by a caulking manner. The area of the first connecting portion 1427 is larger than that of the second connecting portion 1428, so that the deformation element 142 forms a shrinkage shape at the second connecting portion 1428, which is favorable for forming a movable connection at the second connecting portion 1428 and for bending the deformation element 142 near the second connecting portion 1428, thereby obtaining a stable bending state. Because the second connecting portion 1428 is movably connected to the other ends of the first flexible arm 14261 and the second flexible arm 14262 by means of movable riveting, when the bending state of the deformation member 142 changes, the second connecting portion 1428 has a moving space to eliminate the deformation stress generated after the deformation of the deformation member 142, so that the deformation member 142 can be in a stable state after the deformation without resetting, and the stability of the deformation member 142 after the deformation is improved.

In the foregoing embodiments, the descriptions of the embodiments are emphasized, and for parts of one embodiment that are not described in detail, reference may be made to related descriptions of other embodiments.
