Description

Technical Field

[0001] This application belongs to the technical field of terminals, and particularly relates to a wireless earphone and a control method. Background Art

[0002] Currently, wireless earphones can include Open Wearable Stereo (OWS) earphones and True Wireless Stereo (TWS) earphones.

[0003] When wearing OWS earphones, they are not inserted into the ear canals, solving the problem of discomfort caused by in-ear earphones. Moreover, the fully open design of OWS earphones allows users to hear surrounding environmental sounds at any time during wearing, providing higher travel safety. While TWS earphones can form a good seal, effectively isolating external noises, and wearers can have a purer audio experience.

[0004] Thus, the two types of earphones each have their own advantages in different usage scenarios. How to integrate the advantages of the two types of earphones to improve the adaptability of earphones in various different usage scenarios is an urgent problem to be solved. Summary of the Invention

[0007] In a second aspect, the embodiments of this application provide a control method, which is applied to the wireless earphone in the first aspect. The method includes: controlling the telescopic mechanism in the wireless earphone to switch to the extended state to drive at least part of the ear cap mechanism in the wireless earphone to be arranged in the user's ear canal; or, controlling the telescopic mechanism to switch to the retracted state to drive the ear cap mechanism to be located outside the user's ear canal.

[0008] In an embodiment of the present application, the wireless earphone includes: an earphone body, an ear cap mechanism, a telescopic mechanism, and an ear hook portion; the telescopic mechanism is respectively connected to the ear cap mechanism and the earphone body, the ear hook portion is provided on the earphone body, and is connected to the user's ear through the ear hook portion, and the telescopic mechanism switches between an extended state and a retracted state; wherein, when the telescopic mechanism is in the extended state, at least part of the ear cap mechanism is disposed in the user's ear canal; when the telescopic mechanism is in the retracted state, the ear cap mechanism is located outside the user's ear canal, and the wireless earphone is connected to the user's ear through the ear hook portion. In this solution, by providing a telescopic mechanism connected to the ear cap mechanism and the earphone body, on the one hand, when the telescopic mechanism extends, at least part of the ear cap mechanism can extend into the user's ear canal, so that the earphone has a better physical noise reduction effect, that is, at this time the earphone can be used as a TWS earphone; on the other hand, when the telescopic mechanism retracts, the ear cap mechanism can be located outside the user's ear canal, and the wireless earphone can be fixed to the user's ear through the ear hook portion, thereby improving the wearing comfort and travel safety, that is, at this time the earphone can be used as an OWS earphone. Thus, the earphone provided by the embodiment of the present application can flexibly switch between a TWS earphone and an OWS earphone by switching between the extended state and the retracted state of the telescopic mechanism, thereby improving the scenario applicability of the earphone.

Detailed implementation manners

[0028] The technical solutions in the embodiments of the present application will be clearly described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application belong to the scope of protection of the present application.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects before and after.

[0030] The earphone provided by the embodiment of the present application will be described in detail below in conjunction with the accompanying drawings, through specific embodiments and their application scenarios.

[0031] The embodiment of the present application provides an earphone, as Figure 1 shown. The wireless earphone 10 may include: an earphone main body 11, an ear cap mechanism 12, a telescopic mechanism 13, and an ear hook portion 40. The telescopic mechanism 13 is respectively connected to the ear cap mechanism 12 and the earphone main body 11. The ear hook portion 40 is disposed on the earphone main body 11 and is connected to the user's ear through the ear hook portion 40. The telescopic mechanism 13 switches between the extended state and the retracted state.

[0032] Wherein, when the telescopic mechanism 13 is in the extended state, at least a part of the ear cap mechanism 12 is disposed in the user's ear canal;

[0033] When the telescopic mechanism 13 is in the retracted state, the ear cap mechanism 12 is located outside the user's ear canal, and the wireless earphone 10 is connected to the user's ear through the ear hook portion 40.

[0034] It can be understood that when the telescopic mechanism is in the extended state, the length of the ear cap mechanism is suitable for extending into the ear canal; when the telescopic mechanism is in the retracted state, the length of the ear cap mechanism is suitable for being located outside the ear canal.

[0035] In some embodiments of the present application, since the wireless earphone 10 includes an ear hook provided on the earphone main body 11, the wearing stability of the wireless earphone 10 can be improved through the ear hook. It can be understood that the ear hook portion can fix the wireless earphone to the user's ear, so that regardless of whether the ear cap mechanism extends into the user's ear canal, the wireless earphone can be stably worn through the ear hook portion.

[0036] In some embodiments of the present application, such as Figure 6 , Figure 7 , Figure 10 , Figure 11 shown, the telescopic mechanism 13 can be connected to the earphone main body 11 through the first bracket 28 in the earphone main body 11, and the telescopic mechanism 13 is connected to the ear cap mechanism 12 through the second bracket 44 in the ear cap mechanism 12.

[0037] It can be understood that the telescopic mechanism 13 is connected to the first bracket 28 and the second bracket 44, so as to realize the connection with the earphone main body 11 and the ear cap mechanism 12.

[0038] In some embodiments of the present application, the first bracket 28 is fixed in the inner cavity of the earphone main body 11.

[0039] In some embodiments of the present application, the second bracket 44 is fixed on the inner wall of the ear cap mechanism.

[0040] In some embodiments of the present application, the second bracket 44 can be a cross beam fixed on the inner wall of the ear cap.

[0041] In some embodiments of the present application, such as Figure 1 , 7 to Figure 9A any one of the above, the ear cap mechanism 12 may include a flexible sound guiding pipe 14 and an ear cap portion 41;

[0042] One end of the flexible sound guiding pipe 14 is communicated with the sound outlet hole of the ear cap portion 41, and the other end of the flexible sound guiding pipe 14 is connected to the earphone main body 11;

[0043] Wherein, when the telescopic mechanism 13 is in the extended state, the ear cap portion 41 is far away from the earphone main body 11, and the length of the flexible sound guiding pipe 14 is the first length;

[0044] When the telescopic mechanism 13 is in the retracted state, the ear cap portion 41 is close to the earphone main body 11, and the length of the flexible sound guiding pipe 14 is the second length, wherein the first length is greater than the second length.

[0045] In some embodiments of the present application, the telescopic mechanism can be arranged inside the flexible sound guiding pipe or outside the flexible sound guiding pipe.

[0046] It can be understood that when the telescopic mechanism extends, it drives the flexible sound guiding pipe to extend to the first length, so that the overall length of the ear cap mechanism is suitable for extending into the ear canal; or, when the telescopic mechanism retracts, it drives the flexible sound guiding pipe to shorten to the second length, so that the overall length of the ear cap mechanism is suitable for being located outside the ear canal.

[0047] In the embodiments of the present application, by designing an ear cap mechanism on the earphone that can expand and contract with the telescopic mechanism, the user can independently adjust the length of the ear cap mechanism, so as to realize the switching between the two forms of TWS earphones and OWS earphones of the wireless earphone, meeting the needs of the user in different usage scenarios.

[0048] For example, as Figure 2 shown is a schematic structural diagram of the OWS form of the wireless earphone 10, Figure 3 and

[0049] shown is a schematic structural diagram of the TWS form of the wireless earphone 10. It can be seen that when the wireless earphone 10 is in the TWS form, the length of the flexible sound guiding pipe 14 is greater than the length of the flexible sound guiding pipe 14 when the wireless earphone is in the OWS form.

[0050] It should be noted that the cross-section of the sound guiding channel of the flexible sound guiding pipe can be any shape, such as circular, oval, rectangular, etc., which is not limited in the embodiments of the present application. The above "bellows" and "flexible pipe" are only used to indicate that the flexible sound guiding pipe is a component with a sound guiding channel, rather than limiting the shape of the cross-section of the sound guiding channel. That is to say, the pipe of the bellows can be rectangular, circular or any other shape; similarly, the pipe of the flexible pipe can also be rectangular, circular or any other shape.

[0051] In some embodiments of the present application, sound insulation materials such as sound insulation glue or sound insulation cotton can be provided in the flexible sound guiding pipe to improve the sound insulation effect of the earphone and avoid sound leakage.

[0052] In some embodiments of the present application, the flexible sound guiding pipe can be made of a waterproof and sound insulation material.

[0053] In some embodiments of the present application, as Figure 10 shown, the ear cap part 15 includes an ear cap housing 43 and a sound outlet net 42. The sound outlet net 42 is arranged at the sound outlet hole of the ear cap housing 43. The second bracket 44 is connected to the inner wall of the ear cap housing 43. One end of the ear cap housing 43 facing away from the sound outlet net 42 is connected to the flexible sound guiding pipe 14.

[0054] It can be understood that the telescopic mechanism 13 can be connected to the earcap part 15 and the main body of the earphone 10 respectively. During the extension of the telescopic mechanism 13, the earcap part 15 can be driven to move away from the earphone main body 11, and the flexible sound guiding pipe 14 is stretched, so that the length of the earcap mechanism 12 is extended to the length required by the TWS earphone; during the retraction of the telescopic mechanism 13, the earcap part 15 can be driven to move closer to the earphone main body 11, and the flexible sound guiding pipe 14 is compressed, so that the length of the earcap mechanism 12 is shortened to the length required by the OWS earphone.

[0055] In this way, since the earcap mechanism includes a flexible sound guiding pipe, when the telescopic mechanism extends, the telescopic mechanism can drive the flexible sound guiding pipe to extend to a first length, so that the earcap part moves away from the earphone main body. In this way, the earcap part can extend into the user's ear canal so that the wireless earphone can be used as a TWS earphone; and when the telescopic mechanism retracts, it can drive the flexible sound guiding pipe to shorten to a second length, so that the earcap part moves closer to the earphone main body. In this way, the earcap part can be located outside the user's ear canal so that the wireless earphone can be used as an OWS earphone. That is to say, the flexible sound guiding pipe can extend or retract following the telescopic mechanism, so that the earcap part moves away from or closer to the earphone main body, thereby realizing the switching of the wireless earphone between TWS and OWS, so as to improve the scene applicability of the wireless earphone.

[0056] In some embodiments of the present application, such as Figure 8 , Figure 9A and 9B shown, the above-mentioned telescopic mechanism 13 is a scissor mechanism 16; the scissor mechanism 16 includes a first free end 20 and a second free end 21 facing the earphone main body 11, and a third free end 22 and a fourth free end 23 facing the earcap mechanism 12;

[0057] The first free end 20 is slidably connected to the earphone main body 11, the scissor mechanism 16 is rotatably connected to the earphone main body 11, the third free end 22 of the scissor mechanism 16 is slidably connected to the earcap mechanism 12, and the fourth free end 23 of the scissor mechanism 16 is rotatably connected to the earcap mechanism 12.

[0058] In some embodiments of the present application, the first chute and the second chute are arranged in parallel, and both the first chute and the second chute have an included angle with the telescopic direction of the scissor mechanism. For example, both the first chute and the second chute are perpendicular to the telescopic direction of the scissor structure, that is, the included angle is 90 degrees. Of course, in actual implementation, the included angles between the first chute and the second chute and the telescopic direction can also be less than 90 degrees.

[0059] In some embodiments of the present application, the telescopic direction of the scissor mechanism can be the connecting line direction of the first free end and the third free end, or can be the connecting line direction of the second free end and the fourth free end.

[0060] In some embodiments of the present application, the first chute and the second chute can be used to limit the telescopic stroke of the scissors mechanism.

[0061] In some embodiments of the present application, such as Figure 7 , Figure 8 and Figure 9A As shown, a first chute 45 is provided on the earphone body 11, and there is an included angle between the extending direction of the first chute 45 and the telescopic direction of the telescopic mechanism 13. A first protrusion 201 is provided on the first free end 20, and the first protrusion 201 slides in the first chute 45; a second chute 46 is provided on the earcap mechanism 12, and there is an included angle between the extending direction of the second chute 46 and the telescopic direction of the telescopic mechanism 13. A second protrusion 221 is provided on the third free end 22, and the second protrusion 221 slides in the second chute 46.

[0062] Exemplarily, as Figure 8 and Figure 9A As shown, a first chute 45 is provided on the first bracket 28, and the first protrusion 201 on the first free end 20 of the scissors mechanism 16 is slidably connected to the first chute 45, and the second free end 21 of the scissors mechanism 16 is rotatably connected to the first bracket 28; a second chute 46 is provided on the second bracket 44, and the second protrusion 221 on the third free end 22 of the scissors mechanism 16 is slidably connected to the second chute 46, and the fourth free end 23 of the scissors mechanism 16 is rotatably connected to the second bracket 44. In this way, since the telescopic mechanism can be connected to the earphone body through the first bracket and connected to the earcap mechanism through the second bracket, the connection stability between the telescopic mechanism and the earphone body and the earcap mechanism can be improved.

[0063] In this way, since a first chute for slidably connecting the first free end of the scissors mechanism is provided on the earphone body, and a second chute for slidably connecting the third free end of the scissors mechanism is provided in the earcap mechanism, when the scissors mechanism extends or retracts, the first free end and the third free end can slide in the corresponding chutes, and the second free end and the fourth free end can rotate, so as to realize the adjustment of the distance between the end of the earcap mechanism (such as the earcap part) and the earphone body, and thus realize the reliability of the form switching of the wireless earphone.

[0064] In some embodiments of the present application, such as Figure 9A As shown, the scissors mechanism 16 includes at least two scissors units 17 connected in sequence, and adjacent two scissors units 17 are connected by a first rotating shaft 18;

[0065] One scissors unit 17 includes a first connecting rod 171, a second connecting rod 172 and a second rotating shaft 173. The second rotating shaft 173 passes through the middle of the first connecting rod 171 and the second connecting rod 172, so that the first connecting rod 171 and the second connecting rod 172 can rotate relative to the second rotating shaft 173;

[0066] Wherein, the first free end 20 and the second free end 21 are the free ends of different connecting rods in the scissor unit 17 close to the earphone main body 11 in the scissor mechanism 16 and facing the earphone main body 11, and the third free end 22 and the fourth free end 23 are the free ends of different connecting rods in the scissor unit 17 close to the ear cap mechanism 12 in the scissor mechanism 17 and facing the ear cap mechanism 12.

[0067] In some embodiments of the present application, as Figure 9B shown, the scissor mechanism 16 includes a scissor unit 17. A scissor unit 17 includes a third connecting rod 174, a fourth connecting rod 175 and a third rotating shaft 176. The third rotating shaft 176 is disposed through the middle of the third connecting rod 174 and the fourth connecting rod 175, so that the third connecting rod 174 and the fourth connecting rod 175 can rotate relative to the third rotating shaft 176;

[0068] Wherein, one end of the third connecting rod 174 facing the earphone main body 11 is the first free end 20, one end of the third connecting rod 174 facing the ear cap mechanism 12 is the fourth free end 23, one end of the fourth connecting rod 175 facing the earphone main body 11 is the second free end 21, and one end of the fourth connecting rod 175 facing the ear cap mechanism 12 is the third free end 22.

[0069] In this way, since the elongation and shortening of the flexible sound guiding pipe can be realized through one scissor unit, so as to realize the switching between TWS and OWS earphones of the wireless earphone, the structure of the wireless earphone can be simplified on the basis of expanding the form and application scenarios of the wireless earphone.

[0070] In this way, since the first free end of the scissor mechanism facing the earphone main body is slidably connected to the earphone main body, the second free end of the scissor mechanism facing the earphone main body is rotatably connected to the earphone main body, the third free end of the scissor mechanism facing the ear cap mechanism is slidably connected to the ear cap mechanism, and the fourth free end of the scissor mechanism facing the ear cap mechanism is rotatably connected to the ear cap mechanism. Thus, when the first free end is stressed, it can slide relative to the earphone main body, thereby driving the rotation of the remaining scissor units in the scissor mechanism, and further driving the third free end to slide relative to the ear cap mechanism to realize the extension or retraction of the scissor mechanism. In this way, the ear cap mechanism can be driven to elongate or shorten.

[0071] Furthermore, since the scissor mechanism has two connection points with both the earphone main body and the ear cap mechanism, the support stability for the ear cap mechanism can be improved.

[0072] In some embodiments of the present application, as Figure 3 、 6 、7, 12, 13 and 15 shown, the wireless earphone 10 further includes: a limiting mechanism 24, and the limiting mechanism 24 includes a limiting component 25, a first limiting groove 26 and a second limiting groove 27;

[0073] The limiting component 25 is arranged on the side of the first free end 20 away from the first sliding groove 45. The first limiting groove 26 and the second limiting groove 27 are arranged on the first surface 29 of the earphone body 11 facing the ear cap mechanism 12. The first limiting groove 26 and the second limiting groove 27 are arranged along the sliding direction of the first free end 20, and the first limiting groove 26 is located on the side far from the second free end 21;

[0074] Wherein, when the telescopic mechanism 13 is in the retracted state, the first protrusion 201 is located on the side of the first sliding groove 45 away from the second free end 21, and the limiting component 25 is in limiting cooperation with the first limiting groove 26;

[0075] When the telescopic mechanism 13 is in the extended state, the first protrusion 201 is located on the side of the first sliding groove 45 close to the second free end 21, and the limiting component 25 is in limiting cooperation with the second limiting groove 27.

[0076] In some embodiments of the present application, the limiting component and the first convex block are located on both sides of the first free end.

[0077] It can be understood that through the limiting cooperation between the limiting component 25 and the first limiting groove 26 or the second limiting groove 27, the mechanical position of the telescopic mechanism is locked, so that the wireless earphone 10 can be stably in the TWS form or the OWS form.

[0078] In some embodiments of the present application, the connection line of the first limiting groove and the second limiting groove is parallel to the first sliding groove.

[0079] In some embodiments of the present application, as Figures 1 to 15 shown, the above-mentioned first bracket 28 can be an L-shaped bracket. The first limiting groove 26 and the second limiting groove 27 are arranged on the first surface 29 of the L-shaped bracket, and the first sliding groove 45 is arranged on the second surface 50 of the L-shaped bracket. It can be seen that the first surface 29 and the second surface 50 are two perpendicular surfaces of the L-shaped bracket.

[0080] Thus, since the limiting component is arranged at the first free end of the scissor mechanism, and the first limiting groove and the second limiting groove are arranged on the first surface of the earphone body facing the ear cap mechanism, the telescopic mechanism can be kept in the retracted state through the limiting cooperation between the limiting component and the first limiting groove, and the telescopic mechanism can be kept in the extended state through the limiting cooperation between the limiting component and the second limiting groove. In this way, the wireless earphone can be stably in the TWS form or the OWS form under the cooperation of the telescopic mechanism and the limiting mechanism.

[0081] In some embodiments of the present application, as Figure 10 and Figure 11 shown, the limiting component 25 includes a limiting rod 30 and a limiting housing 31;

[0082] One end of the limiting rod 30 is connected to the side of the first free end 20 facing away from the first chute 45, and the other end of the limiting rod 30 is connected to the limiting housing 31. The limiting housing 31 includes an outer shell 311, a limiting spring 312 and a limiting ball 313. The limiting spring 312 is arranged in the outer shell 311, and one end of the limiting spring 312 is connected to the inner wall of the outer shell 311 facing the first surface 29, and the other end of the limiting spring 312 is connected to the limiting ball 313, and the limiting ball 313 can expand and contract in the outer shell 311 under the drive of the limiting spring 312;

[0083] Wherein, when the limiting assembly 25 is in limiting cooperation with the first limiting groove 26 or the second limiting groove 27, at least part of the limiting ball 313 extends out of the outer shell 311;

[0084] When the limiting assembly 25 is separated from the first limiting groove 26 or the second limiting groove 27, the limiting ball 313 is received in the outer shell 311.

[0085] It can be understood that as Figures 6 to 15 shown, when the limiting assembly 25 moves to the first limiting groove 26 along with the first free end 20 of the scissor mechanism 16, the limiting spring 312 can pop the limiting ball 313 out of the outer shell 311 and make the limiting ball 313 in limiting cooperation with the first limiting groove 26, so as to realize the limitation of the first free end 20 of the scissor mechanism 16, and further make the scissor mechanism 16 stably in a compressed state; similarly, when the limiting assembly 25 moves to the second limiting groove 27 along with the first free end 20 of the scissor mechanism 16, the limiting spring 312 can pop the limiting ball 313 out of the outer shell 311 and make the limiting ball 313 in limiting cooperation with the second limiting groove 27, so as to realize the limitation of the first free end 20 of the scissor mechanism 16, and further make the scissor mechanism 16 stably in an extended state.

[0086] Furthermore, when an external force parallel to the first chute 45 acts on the first free end 20 of the scissor mechanism 16, the limiting ball 313 will be subjected to a force in the same direction, so as to squeeze the limiting ball 313 out of the first limiting groove 26 or the second limiting groove 27, so that the first free end 20 can slide along the first chute 45, and thus the extension and compression of the scissor mechanism 16 can be switched.

[0087] In some embodiments of the present application, as Figure 6 shown, a limiting chute 47 parallel to the first chute 45 is arranged on the first surface 29, and the first limiting groove 26 and the second limiting groove 27 are arranged in the limiting chute 47.

[0088] As Figure 6As shown, the limit spring 312 and the limit ball 313 are accommodated in the shell 31. When the wireless headset 10 is in the OWS form, the limit spring 312 presses the limit ball 313, and the scissors mechanism 16 maintains the OWS form; when the wireless headset 10 is in the process of switching from the OWS form to the TWS form, the limit assembly will move forward along the limit slot 47. When the wireless headset 10 is switched to the TWS form, the limit assembly is located at the position of the second limit slot 27, and the limit spring 312 presses the limit ball 313 again, and the scissors mechanism 16 will maintain the TWS form.

[0089] In this way, since the limit assembly includes a limit rod and a limit shell connected to each other, one end of the limit rod is connected to the side of the first free end away from the first slide groove, and the other end of the limit rod is connected to the limit shell, the limit shell includes a shell, a limit spring and a limit ball, the limit spring is arranged in the shell, and one end of the limit spring is connected to the inner wall of the shell facing the first surface, and the other end of the limit spring is connected to the limit ball, and the limit ball can be retracted and extended in the shell under the drive of the limit spring; so that when the limit assembly is limitedly matched with the first limit groove or the second limit groove, the limit ball at least partially extends out of the shell; when the limit assembly is separated from the first limit groove or the second limit groove, the limit ball is accommodated in the shell, so that the scissor mechanism 16 can be limited, so that the wireless headset 10 can stably maintain the TWS form or the OWS form, so that the stability of the form switching of the wireless headset 10 can be improved.

[0090] Of course, the limiting mechanism 24 can also be a push-type buckle structure, or a magnetic component. For the description of the push-type buckle structure, refer to the relevant description of the push-type buckle structure in the above embodiment.

[0091] In some embodiments of the present application, the magnetic assembly may include a permanent magnet and an electromagnet that are arranged opposite to each other, wherein the permanent magnet may be arranged in the ear cap mechanism, and the electromagnet may be arranged in the earphone body.

[0092] Specifically, the permanent magnet can be arranged on the surface of the second bracket facing the earphone body, and the electromagnet can be arranged on the first surface of the first bracket. In this way, the strength of the magnetic field generated by the electromagnet can be adjusted by adjusting the electrical information applied to the electromagnet, thereby adjusting the force between the electromagnet and the permanent magnet.

[0093] It can be understood that by adjusting the direction and magnitude of the current applied to the electromagnet, the strength and direction of the magnetic field generated by the electromagnet can be adjusted, thereby adjusting the force between the electromagnet and the permanent magnet.

[0094] For example, if the magnetic field direction generated by the electromagnet is the same as that of the permanent magnet, a repulsive force is generated between the electromagnet and the permanent magnet. If the magnetic field direction generated by the electromagnet is opposite to that of the permanent magnet, an attractive force is generated between the electromagnet and the permanent magnet.

[0095] In this way, since the limiting mechanism can limit the telescopic mechanism to be in the extended state or the retracted state, the length of the ear cap mechanism can be stably maintained at the length required for TWS wireless earphones or the length required for OWS wireless earphones. Therefore, the wireless earphones provided by the embodiments of the present application can reliably be in the OWS form or the TWS form.

[0096] In some embodiments of the present application, as Figures 1 to 15 shown, the above-mentioned wireless earphone 10 further includes: a driving mechanism 34, and the driving mechanism 34 includes a first shape memory alloy member 35 and a second shape memory alloy member 36 arranged in parallel;

[0097] The first ends of the first shape memory alloy member 35 and the second shape memory alloy member 36 are respectively connected to the first free end 20, the second end of the first shape memory alloy member 35 is connected to the earphone main body 11, and the second end of the second shape memory alloy member 36 is slidably connected to the earphone main body 11;

[0098] Wherein, the first shape memory alloy member 35 elongates when an electrical signal is applied, so as to drive the scissor mechanism 16 to switch to the extended state;

[0099] Or,

[0100] The second shape memory alloy member 36 shortens when an electrical signal is applied, so as to drive the scissor mechanism 16 to switch to the retracted state.

[0101] In some embodiments of the present application, when an electrical signal is applied to the first shape memory alloy member, the first shape memory alloy member elongates based on Joule heat to drive the scissor mechanism to switch to the extended state; or, when an electrical signal is applied to the second shape memory alloy member, the second shape memory alloy member shortens based on Joule heat to drive the scissor mechanism to switch to the retracted state.

[0102] It should be noted that when an electrical signal is applied to the first shape memory alloy member, no electrical signal is applied to the second shape memory alloy member. Similarly, when an electrical signal is applied to the second shape memory alloy member, no electrical signal is applied to the first shape memory alloy member.

[0103] It can be understood that the first shape memory alloy member is used to drive the scissor mechanism to extend, and the second shape memory alloy member is used to drive the scissor mechanism to contract or fold.

[0104] In some embodiments of the present application, the first shape memory alloy member and the second shape memory alloy member are two-way shape memory alloy members, that is, they return to the shape before heating when the temperature is lower than the transformation temperature. It can be understood that this transformation temperature can also be referred to as the phase change temperature.

[0105] In some embodiments of the present application, as Figure 9A shown, the second end of the first shape memory alloy member 35 is connected to the first bracket 28, such as fixedly connected.

[0106] In some embodiments of the present application, as Figure 8 shown, a third sliding groove 51 can be provided on the second surface 50 of the first bracket 28, and the second end of the second shape memory alloy member 36 is slidably connected to the third sliding groove 51. When the first shape memory alloy member 35 expands and elongates due to heat, pushing the first free end 20 of the scissor mechanism 16 to move towards the second free end 21, that is, when sliding in the first sliding groove 45, the second end of the second shape memory alloy member 36 can slide in the third sliding groove 51, so as to ensure that the second shape memory alloy member 36 does not deform during the elongation process of the first shape memory alloy member 35.

[0107] For other descriptions of the first shape memory alloy member 35 and the third shape memory alloy member 36, refer to the relevant descriptions of the first shape memory alloy member in the above embodiments. To avoid repetition, they will not be elaborated here.

[0108] In some embodiments of the present application, the first shape memory alloy member is made of a heat-expanded type shape memory alloy, and the second shape memory alloy member is made of a heat-shrunk type shape memory alloy.

[0109] In some embodiments of the present application, both the first shape memory alloy member and the second shape memory alloy member are shape memory alloy wires.

[0110] In some embodiments of the present application, as Figure 5 shown, both ends of the first shape memory alloy member 35 are respectively connected to the main circuit of the wireless earphone 10 through two wires 49, and both ends of the second shape memory alloy member 36 are respectively connected to the main circuit of the wireless earphone 10 through another two wires 49; the main circuit board 38 can apply electrical information to both ends of the first shape memory alloy member 35 or the second shape memory alloy member 36.

[0111] In this way, since the telescopic mechanism 13 can be driven by the driving mechanism 34 to switch between the extended state and the retracted state, the wireless earphone 10 is stably and reliably in the OWS form or the TWS form.

[0112] Next, taking the telescopic mechanism as the scissor mechanism and the driving mechanism as the first shape memory alloy member and the second shape memory alloy member as an example, the working process of the wireless earphone provided by the embodiments of the present application will be described.

[0113] In some embodiments of the present application, the user can automatically switch the earphone from the OWS form to the TWS form, and the specific implementation process is as follows:

[0114] As Figures 1 to 15 shown, after the user presses the state switching part, the first shape memory alloy piece heats up and elongates. One end of the SMA wire is fixed on the first bracket 28, and the other end is fixed on the scissor mechanism 16. One end of the lower half of the scissor mechanism 16 is fixed on the first bracket 28, and the other end can move along the first chute 45 of the scissor mechanism. One end of the upper half of the scissor mechanism 16 is fixed on the earcap mechanism 12, and the other end can move along the upper chute of the scissor mechanism. Therefore, in the process of the elongation of the first shape memory alloy piece, it pushes the scissor mechanism 16 forward, causing the scissor mechanism 16 to contract, the telescopic support tube to unfold, and the earcap mechanism 12 to be lifted up.

[0115] One end of the second shape memory alloy piece is fixed on the scissor mechanism 16, and the other end can move in the limit chute 47 of the scissor mechanism bracket, so as to ensure that the second shape memory alloy piece 36 will not deform during the elongation of the first shape memory alloy piece 35.

[0116] When the inspection mechanism contracts to a predetermined position, the infrared receiving hole 52 will be blocked by the scissor mechanism, thereby feeding back a signal to the main board to disconnect the circuit of the first shape memory alloy piece.

[0117] There is a limit mechanism on the other side of the scissor mechanism. The limit spring 13 and the limit ball 14 are embedded in the limit rod 30. When the earphone is in the OWS form, the limit spring 13 presses the limit ball 14 to limit the scissor mechanism 16 at the position of the first limit groove, so that it maintains the OWS form. When the earphone is in the process of switching from the OWS form to the TWS form, the limit rod 30 will move forward along the limit chute 47. When the earphone switches to the TWS form and is completed, the scissor mechanism 16 will be limited at the position of the second limit groove 27, so that it maintains the TWS form.

[0118] When the user needs to switch the earphone from the TWS form to the OWS form, the user can press the mechanical button 37 again, which will trigger the second shape memory alloy piece to be powered on. After the second shape memory alloy piece is heated, it will contract. As Figure 15 shown, since one end of the second shape memory alloy piece has reached the outermost edge of the SMA wire chute and the other end is fixed on the scissor mechanism 16, the contraction of the second shape memory alloy piece will pull the scissor mechanism 16 back, so that the scissor mechanism 16 disengages from the position of the second limit groove. At this time, the first shape memory alloy piece has a restoring force to return to its original length (the shape memory alloy wire is prone to elastic deformation at normal temperature), causing the scissor mechanism 16 to return to the position of the first limit groove, so that the scissor mechanism 16 expands, the flexible sound guiding pipe 14 folds, and the earcap 7 is retracted, making the earphone return to the OWS form.

[0119] Thus, when the user presses the mechanical button, the first shape memory alloy component is energized and heated, causing the first shape memory alloy component to elongate, driving the scissor structure and the flexible sound guide pipe 14 to move upward, so that the ear cap elongates and transforms into the form of a TWS earphone. At this time, the limiting ball 14 is limited at the position of the second limiting groove, maintaining the form of the TWS earphone after power-off; after the user presses the button again, the second shape memory alloy component is energized and heated, causing the second shape memory alloy component to contract, driving the scissor mechanism 16 and the flexible sound guide pipe 14 to move downward, so that the ear cap contracts and transforms into the form of an OWS earphone. At this time, the limiting ball 14 is limited at the position of the first limiting groove, maintaining the form of the OWS earphone after power-off.

[0120] In the wireless earphone provided by the embodiment of the present application, by providing a telescopic mechanism connected to the ear cap mechanism and the earphone body, on the one hand, when the telescopic mechanism extends, at least part of the ear cap mechanism can extend into the user's ear canal, so that the earphone has a better physical noise reduction effect, that is, the earphone can be used as a TWS earphone at this time; on the other hand, when the telescopic mechanism retracts, the ear cap mechanism can be located outside the user's ear canal, and the wireless earphone is fixed to the user's ear through the ear hook part, so that the wearing comfort and travel safety can be improved, that is, the earphone can be used as an OWS earphone at this time. Thus, the earphone provided by the embodiment of the present application can flexibly switch between a TWS earphone and an OWS earphone by switching the extended state and the retracted state of the telescopic mechanism, thereby improving the scene applicability of the earphone.

[0121] The embodiment of the present application provides a control method, which is applied to Figures 1 to 15 the wireless earphone shown in Figure 16 FIG. shows a schematic flowchart of the control method provided by the embodiment of the present application. As Figure 16 shown, the control method may include the following step 1601.

[0122] Step 1601: The wireless earphone controls the telescopic mechanism in the wireless earphone to switch to the extended state, so as to drive at least part of the ear cap mechanism in the wireless earphone to be arranged in the user's ear canal; or, the wireless earphone controls the telescopic mechanism in the wireless earphone to switch to the retracted state, so as to drive the ear cap mechanism in the wireless earphone to be located outside the user's ear canal.

[0123] In some embodiments of the present application, the control method provided by the embodiment of the present application may further include the following step 1602 and step 1603. The above step 1601 may be implemented by the following step 1061A, or the above step 1601 may be implemented by the following step 1061B.

[0124] Step 1603: The earphone detects the state switching information through the state switching part in the earphone.

[0125] Step 1604: The wireless earphone detects the status information of the telescopic mechanism through the status detection unit in the wireless earphone, and this status information is used to indicate whether the telescopic mechanism is in the extended state.

[0126] Among them, the above status switching information is the status switching instruction input by the user. That is to say, detecting the status switching information means that the user needs to switch the status of the wireless earphone.

[0127] In some embodiments of the present application, the wireless earphone can control the telescopic mechanism to switch to the extended state or the retracted state based on the status switching information.

[0128] Step 1601A: When the wireless earphone detects the status switching information and the above status information indicates that the telescopic mechanism is not in the extended state, it controls the telescopic mechanism to switch to the extended state.

[0129] Step 1601B: When the wireless earphone detects the status switching information and the above status information indicates that the telescopic mechanism is in the extended state, it controls the telescopic mechanism to switch to the retracted state.

[0130] In some embodiments of the present application, the wireless earphone can drive the telescopic mechanism to switch to the extended state or the retracted state through the driving mechanism in the earphone.

[0131] In some embodiments of the present application, when the status information indicates that the telescopic mechanism is not in the extended state, the wireless earphone drives the telescopic mechanism to switch to the extended state based on the status switching information through the driving mechanism; or, when the status information indicates that the telescopic mechanism is in the extended state, the wireless earphone drives the telescopic mechanism to switch to the retracted state based on the status switching information through the driving mechanism.

[0132] In some embodiments of the present application, when the status information indicates that the telescopic mechanism is not in the extended state, the wireless earphone driving the telescopic mechanism to switch to the extended state based on the status switching information through the driving mechanism may include:

[0133] When the status information indicates that the telescopic mechanism is not in the extended state, based on the status switching information, electrical information is applied to the first shape memory alloy element in the driving mechanism, so that the first shape memory alloy element elongates based on Joule heat and drives the scissor mechanism to switch to the extended state.

[0134] In some embodiments of the present application, when the status information indicates that the telescopic mechanism is in the extended state, the wireless earphone driving the telescopic mechanism to switch to the retracted state based on the status switching information through the driving mechanism may include:

[0135] When the state information indicates that the telescopic mechanism is in the extended state, based on the state switching information, electrical information is applied to the second shape memory alloy member in the drive mechanism, so that the second shape memory alloy member shortens based on Joule heat, driving the scissors mechanism to switch to the retracted state.

[0136] In some embodiments of the present application, after applying electrical information to the first shape memory alloy member in the drive mechanism of the above wireless earphone, when the state detection unit detects the state information indicating that the telescopic mechanism is in the extended state, the application of electrical information to the first shape memory alloy member is stopped.

[0137] In some embodiments of the present application, after applying electrical information to the second shape memory alloy member in the drive mechanism of the above wireless earphone, when the state detection unit detects the state information indicating that the telescopic mechanism is not in the extended state, the application of electrical information to the second shape memory alloy member is stopped;

[0138] Wherein, after stopping applying electrical information to the second shape memory alloy member, the telescopic mechanism continues to retract under the action of the deformation force of the first shape memory alloy member until it is in the retracted state.

[0139] In this way, since the telescopic mechanism in the earphone can be controlled to extend so that at least part of the earcap mechanism of the wireless earphone extends into the ear canal, the wireless earphone has a better physical noise reduction effect, that is, the wireless earphone can be used as a TWS earphone at this time; on the other hand, the telescopic mechanism can be controlled to retract so that the earcap mechanism is located outside the ear canal, thereby improving the wearing comfort and travel safety, that is, the earphone can be used as an OWS earphone at this time. In this way, the control method provided by the embodiments of the present application can flexibly switch the wireless earphone between the TWS earphone and the OWS earphone by switching the extended state and the retracted state of the telescopic mechanism, thereby improving the scene applicability of the wireless earphone.
