Description

Technical Field

[0001] The present application relates to the field of earphone technology, and in particular to an open earphone. Background Technology

[0002] Open-back headphones are headphones that do not need to go deep into the ear canal, so users can maintain awareness of the surrounding environment while enjoying music or calls. Among open-back headphones, ear hooks and ear clips are two common designs. The ear hooks fix the headphones above the ears and are supported by a frame that surrounds the ears to provide stability and comfort. Open-back headphones are fixed by clipping on the auricle.

[0003] Open-type headphones usually include two compartments and a bridge connecting the two compartments. The speaker and the battery are respectively arranged in one compartment. Therefore, open-type headphones usually also need to be provided with wiring to connect the speakers and batteries located in the two compartments.

[0004] In the related art, when the wiring passes through the connecting bridge, in-mold injection molding is mainly used, and two injection moldings are required to complete the complete wrapping of the connecting bridge on the wiring. However, the shape of the wiring is difficult to control during injection molding, and it is easy to break, resulting in the scrapping of the entire injection molding product, which is costly. Contents of utility model

[0005] The embodiment of the present application provides an open-type headphone, which can improve the yield of open-type headphone products and reduce production costs.

[0006] In a first aspect, an embodiment of the present application provides an open-type earphone, comprising a sound-emitting component, a fixing component, a connecting bridge, and an electrical connector; the sound-emitting component comprises a first shell and a first electrical component, the first electrical component being disposed in the first shell; the fixing component comprises a second shell and a second electrical component, the second electrical component being disposed in the second shell; the two ends of the connecting bridge are respectively connected to the first shell and the second shell, a wiring channel is disposed in the connecting bridge; the electrical connector can be movably disposed in the wiring channel, and one end of the electrical connector extends into the first shell and is electrically connected to the first electrical component, and the other end extends into the second shell and is electrically connected to the second electrical component.

[0007] The open earphone based on the embodiment of the present application has a wiring channel provided in the connection bridge, and the electrical connector can pass through the wiring channel to realize the electrical connection between the first electrical component and the second electrical component in the two housings. Through the design of the wiring channel, during the assembly and production process, the electrical connector can be hiddenly arranged by threading it through the wiring channel in the later stage, without the need to assemble the electrical connector to the connection bridge by means of multiple injection molding productions as in the traditional production method. This can effectively avoid the situation where the electrical connector is displaced due to improper fixation or damaged by high temperature during the injection molding production process, thereby improving the production yield of the open earphone and reducing the production cost. Moreover, the advantage of such a design is that since the electrical connector of the present application can be movably passed through the wiring channel, when the open earphone is worn, even if the connection bridge is bent, because the electrical connector can be adaptively adjusted in the wiring channel, the risk of the electrical connector being broken can be effectively reduced. And during the later use process, if the electrical connector is damaged, it is also beneficial to replace the electrical connector, thereby extending the service life of the open earphone.

[0020] To make the purpose, technical solutions and advantages of this application clearer, the following will further describe the embodiments of this application in detail with reference to the accompanying drawings.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs. The terms used in the description of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] As a commonly used electronic product, headphones play an important role in people's lives. They receive the electrical signals sent by a media player or receiver and convert them into audible sound waves using speakers close to the ears. They can be listened to alone without disturbing others; they can also block out the surrounding noise, which is very helpful for people using them in noisy environments such as recording studios, for DJs, during travel, and during exercise. Headphones can be classified into air-conduction headphones, bone-conduction headphones, etc. according to their sound generation mechanism. When classified by wearing method, they include over-ear headphones, ear-hook headphones, open-back headphones, etc.

[0025] Open-back headphones are a type of headphones that do not need to be inserted into the ear canal. Users can enjoy music or make calls while remaining aware of the surrounding environment. Among open-back headphones, ear-hook and ear-clamp are two common design forms. Ear-hook headphones are fixed above the ear and supported by a frame that wraps around the ear, providing stability and comfort, while open-back headphones are fixed by clamping onto the auricle.

[0026] For open-back headphones, they generally include two housing bodies and a connecting bridge connecting the two housing bodies. The speakers and the battery are respectively arranged in one housing body. Therefore, open-back headphones usually also need to be provided with wiring to connect the speakers and the battery located in the two housing bodies.

[0027] In the related art, when the wiring passes through the connecting bridge, in-mold injection molding is mainly used, and two injections are required to completely wrap the connecting bridge around the wiring. However, the shape of the wiring during injection molding is not easy to control, and it is prone to breakage, resulting in the scrapping of the entire injection-molded product and high costs.

[0028] To solve the above problems, an embodiment of this application proposes an open-back headphone that can be communicatively connected to devices such as mobile phones, computers, MP3 players, and wearable audio devices.

[0029] Please refer to Figures 1 to 3 , in Figures 1 to 3In the exemplary solution shown, the open earphone 10 is taken as an example of an ear-clip earphone for expansion. In the embodiments of the present application, the open earphone 10 includes a sound generating component 110, a fixing component 120, a connecting bridge 130, and an electrical connector 140. The two ends of the connecting bridge 130 are respectively connected to the sound generating component 110 and the fixing component 120. The connecting bridge 130 can be bent. For example, when the open earphone 10 is an ear-clip earphone, the connecting bridge 130 can be in a "C" shape or a "U" shape, etc. In an ear-hook earphone, the connecting bridge 130 is in an arc-shaped structure that bends around the user's ear. The sound generating component 110, the connecting bridge 130, and the fixing component 120 cooperate to form a wearing space 150. The connecting bridge 130 gives an elastic clamping force during the wearing process of the earphone. Specifically, the sound generating component 110 abuts against the front of the user's ear, while the fixing component 120 is located on the back of the user's ear. The user's ear can be located within the wearing space 150, and the user's ear is clamped by the cooperation of the sound generating component 110 and the fixing component 120.

[0030] When the open earphone 10 is an ear-hook earphone, the connecting bridge 130 is generally hook-shaped and can extend on the back side of the user's ear to hook on the ear. Similarly, the sound generating component 110 is located on the front of the ear, while the fixing component 120 is located on the back of the ear. The difference from the form of the ear-clip earphone is that the connecting bridge 130 is not mainly used to provide a clamping force during the wearing process.

[0031] The sound generating component 110 includes a first housing 111 and a first electrical component (not shown), and the first electrical component is arranged inside the first housing 111. The first housing 111 can be in an ellipsoidal shape, a flat three-dimensional structure, etc. The first housing 111 can be made of materials such as plastic and silica gel. For example, it can be made of hard plastic as the inner shell wall, and then a flexible material layer, such as a silica gel layer, etc., is coated on the outside to make its touch better. The first housing 111 has a sound outlet hole 112. Among them, the first electrical component can be a speaker unit. During use, the sound emitted by the speaker unit enters the user's ear canal through the sound outlet hole 112 and the user's ear canal opening. It should be noted that during the wearing process of the open earphone 10 of the present application, the sound generating component 110 does not enter the ear canal, and the sound outlet hole 112 faces the user's ear canal opening.

[0032] The fixed component 120 includes a second housing 121 and a second electrical component (not shown). The second electrical component is disposed within the second housing 121. It can be understood that the open earphone 10 further includes a control circuit board and a battery. Among them, the control circuit board can be disposed within the first housing 111 together with the speaker unit, or the control circuit board can also be disposed within the second housing 121 together with the battery. Thus, the electrical connector 140 of the present application can electrically connect the battery and the control circuit board, or can electrically connect the speaker unit and the control circuit board. That is to say, the first electrical component of the present application can be the control circuit board or the speaker unit, and the second electrical component can be the battery or the control circuit board. Among them, the battery can be in the form of a rechargeable lithium battery. During operation, the battery supplies power to the control circuit board and the speaker unit.

[0033] Regardless of whether the control circuit board is disposed within the first housing 111 or the second housing 121, the open earphone 10 of the present application needs to achieve electrical connection of the electronic components within the first housing 111 and the second housing 121. Thus, the electrical connector 140 needs to penetrate the connection bridge 130 to achieve electrical conduction between the first electrical component and the second electrical component. It can be understood that during actual operation, both the speaker unit and the battery are connected to the control circuit board. The control circuit board provides power and control signals to the speaker unit. Therefore, in one setting form, when the first electrical component is the speaker unit and the second electrical component is the control circuit board, that is, when the control circuit board and the battery are disposed within the second housing 121 together, the electrical connector 140 physically connects the speaker unit and the control circuit board, and the electrical connector 140 can transmit the power and control signals of the control circuit board to the speaker unit to achieve the normal sound output function of the speaker unit.

[0034] Please refer to Figure 4 , to implement the arrangement of the electrical connector 140, the present application further provides a wire routing channel 134 within the connection bridge 130; the electrical connector 140 is movably disposed through the wire routing channel 134. One end of the electrical connector 140 extends into the first housing 111 and is electrically connected to the first electrical component, and the other end extends into the second housing 121 and is electrically connected to the second electrical component. Further, in the solution of the present application, the electrical connector 140 is movable along the length direction of the wire routing channel 134, which facilitates the wire threading operation. Specifically, the electrical connector 140 can be pulled relative to the inner wall of the wire routing channel 134.

[0035] Based on the open earphone 10 of the embodiments of the present application, by providing a wire routing channel 134 within the connection bridge 130, the electrical connector 140 can pass through the wire routing channel 134 to achieve electrical connection between the first electrical component and the second electrical component within the two housings. Through the design of the wire routing channel 134, during the assembly and production process, the electrical connector 140 can be passed through the wire routing channel 134 in a later stage by threading, and the electrical connector 140 can be arranged in a concealed manner, without the need to assemble the electrical connector 140 to the connection bridge 130 in the form of multiple injection moldings as in the traditional production method. This can effectively avoid the situation where the electrical connector 140 is displaced or damaged by high temperature due to improper fixation during the injection molding production process, improving the production yield of the open earphone 10 and reducing the production cost. Moreover, the advantage of such a design is that since the electrical connector 140 of the present application is movably passed through the wire routing channel 134, even when the connection bridge 130 is bent during the wearing process of the open earphone, because the electrical connector 140 can be adaptively adjusted within the wire routing channel 134, the risk of the electrical connector 140 being broken can be effectively reduced. During the later use process, if the electrical connector 140 is damaged, it is also beneficial for the replacement of the electrical connector 140, thereby extending the service life of the open earphone 10.

[0036] In one embodiment, the connection bridge 130 includes an outer sheath 131 and a shape memory metal member 132. The shape memory metal member 132 is received within the outer sheath 131. The two ends of the outer sheath 131 are respectively connected to the first housing 111 and the second housing 121, and a wire routing channel 134 is provided within the outer sheath 131.

[0037] Among them, the outer sheath 131 can be made of a material with a certain elasticity, such as plastic, silicone, etc. The shape memory metal member 132 can be a titanium wire. The shape memory metal member 132 is in a long strip shape and extends along the length direction of the outer sheath 131. The shape memory metal member 132 being wrapped by the outer sheath 131 can enable the connection bridge 130 to have better deformation and resilience capabilities. During the production process, the shape memory metal member 132 can be fixed to the outer sheath 131 in a pre-buried manner. The wire routing channel 134 can be formed together with the outer sheath 131 during the molding process. In one implementation form, a dummy wire body can be injection molded with the outer sheath 131 in a pre-buried manner. After the injection molding, the material of the dummy wire body is separated from the outer sheath 131, and the position originally occupied by the dummy wire body forms the wire routing channel 134.

[0038] In the present application, the shape memory metal part 132 and the wire routing channel 134 extend in parallel along the length direction of the outer sheath 131. Among them, the wire routing channel 134 and the shape memory metal part 132 are separated from each other, and the arc along which the wire routing channel 134 extends is equivalent to the arc of the shape memory metal part 132. In this way, during the bending and deformation process of the entire connection bridge 130, since the electrical connector 140 can move freely within the wire routing channel 134, the electrical connector 140 can be prevented from being broken.

[0039] It can be understood that in other embodiments, the connection bridge 130 of the present application may not be provided with the shape memory metal part 132, but only consists of the outer sheath 131, and the outer sheath 131 can be made of materials with certain elastic recovery ability, such as plastics, silica gels, metals and other materials, and the present application does not limit this.

[0040] The electrical connector 140 may have a sheet-like structure part or a wavy structure part within the wire routing channel 134. Among them, the shape of the wire routing channel 134 is adapted to the shape of the electrical connector 140. Such a setting is conducive to maintaining the stable posture of the electrical connector 140 during the wire threading process and preventing torsion, so that the wire threading process is smoother.

[0041] In one setting form, the electrical connector 140 further includes a first bending section 142, a main body section 141, and a second bending section 143 that are connected in sequence; the main body section 141 extends within the wire routing channel 134, the first bending section 142 extends in a zigzag manner within the first housing 111 and is electrically connected to the first electrical component, and the second bending section 143 extends in a zigzag manner within the second housing 121 and is electrically connected to the second electrical component.

[0042] During the actual use of the open earphone 10 in this embodiment, when the connection bridge 130 is bent and deformed, it further causes the pulling of the electrical connector 140. Since the electrical connector 140 is provided with the first bending section 142 and the second bending section 143, the entire electrical connector 140 can be given more stretching movement by the first bending section 142 and the second bending section 143. In this way, during the bending and deformation process of the connection bridge 130, it will not cause the pulling of the connection position between the electrical connector 140 and the first electrical component, nor the pulling of the connection position between the electrical connector 140 and the second electrical component, thereby effectively ensuring the conductive contact and improving the operation stability of the entire open earphone 10.

[0043] Furthermore, the first bending section 142 bends around the first electrical component along the first bending direction, and the second bending section 143 bends around the second electrical component along the second bending direction, where the first bending direction is different from the second bending direction.

[0044] In Figures 2 to 4In one form exemplarily shown, the first bent section 142 extends by bending around the side of the first electrical component facing away from the connection bridge 130; while the second bent section 142 extends by bending around the side of the second electrical component facing the connection bridge 130. By such an arrangement, while achieving a reasonable layout of the circuit, a relatively short wiring can be adopted, and as much stretching movement as possible can be provided during the bending deformation process of the connection bridge 130, so that the phenomenon of the welding and power connection position of the electrical connector 140 being pulled can be effectively reduced, and the stability of power connection can be improved.

[0045] In addition, the main body section 141 can be a sheet-like structure or a wavy structure. In the case where the main body section 141 is a sheet-like structure, the thickness direction of the main body section 141 can be set to be the same as the thickness direction of the connection bridge 130. By such an arrangement, during the bending deformation process of the connection bridge 130, the deformation directions of the main body section 141 are the same, so that the risk of the main body section 141 being damaged due to stress concentration can be effectively reduced. In the case where the main body section 141 is a wavy structure, a greater deformation amount during the pulling process is given to the entire electrical connector 140, and the risk of the electrical connector 140 being damaged itself and the electrical welding position becoming loose due to pulling during the bending deformation process of the connection bridge 130 can also be reduced.

[0046] In one embodiment, the electrical connector 140 can be in the form of a flexible printed circuit board (FPC), so that the power supply and signal transmission of the first electrical component can be realized in the form of a smaller number of wire bodies. In this way, when the flexible printed circuit board has a wavy structure part, during the bending deformation process of the flexible printed circuit board along with the connection bridge 130, it has a greater deformation ability, so that it is not easy to break and crack, and thus has a longer service life. It can be understood that the electrical connector 140 of the present application can also be in other wire body forms, such as multiple single-core cables, multi-core cables, etc., and the present application does not limit this.

[0047] In the present application, one end of the outer sheath 131 can be detachably connected to the first housing 111, and the other end is fixedly connected to the second housing 121. In this case, in order to have a higher wire threading efficiency during the production process, the second housing 121 can be set in the form of a plurality of sub-housings spliced in a split manner, and the outer sheath 131 is fixedly connected to one of the sub-housings, so that wire threading is carried out when the second housing 121 is open. Of course, it can also be that one end of the outer sheath 131 is fixedly connected to the first housing 111, and the other end is detachably connected to the second housing 121. The wire threading process of such a form is similar to the above content and will not be elaborated here.

[0048] In addition, both ends of the outer cover 131 of the present application can be detachably connected to the first housing 111 and the second housing 121 respectively. With such a setting, the electrical connector 140 can be pre-passed through the connection bridge 130 and then assembled with the first housing 111 and the second housing 121, so as to achieve modular assembly, which can greatly improve production efficiency. And it is also convenient to perform wiring operations after detaching the connection bridge 130 during later maintenance.

[0049] Please refer to Figures 5 to 8 , in a specific detachable connection form, both ends of the outer cover 131 are snap-connected to the first housing 111 and the second housing 121 respectively.

[0050] Specifically, in one setting form, the open earphone 10 of the present application can also be provided with connection parts 135 at both ends of the outer cover 131. The outer cover 131 is arc-shaped. The two connection parts 135 are respectively connected to both ends of the outer cover 131. The shape memory metal part 132 extends inside the outer cover 131, and both ends of the shape memory metal part 132 respectively extend into the corresponding connection part 135. Among them, the connection part 135 is provided with a buckle 137, and both the first housing 111 and the second housing 121 are provided with snap-through grooves 113. The buckle 137 is snapped into the snap-through groove 113.

[0051] In this embodiment, connection parts 135 are provided at both ends of the outer cover 131. Among them, the hardness of the connection part 135 is greater than that of the outer cover 131. The two can be formed into an integral structure by secondary injection molding, or fixed into an integral body by bonding, hot melting and other forms. In this way, the outer cover 131 mainly realizes the function of deforming to generate resilience, while the connection part 135 plays a connecting function. In this way, the connection is more firm by using the connection part 135 with greater hardness. The connection part 135 and the first housing 111 and the second housing 121 adopt a snap connection form. During the assembly process, fewer other tools are needed and the disassembly and assembly are more convenient.

[0052] Specifically, the connection part 135 includes a base body 136. The above-mentioned buckle 137 is connected to the base body 136. The cross-section of the buckle 137 is generally in the shape of a "7". The buckle 137 protrudes from one side of the base body 136. In this way, a limiting groove is formed by the cooperation between the buckle 137 and the base body 136. During the assembly process, the buckle 137 passes through the snap-through groove 113, and the wall of the first housing 111 is embedded in the limiting groove, while the hook part of the buckle 137 abuts against the inner wall of the first housing 111, so as to realize the relative fixation of the connection part 135 and the first housing 111.

[0053] Further, in order to improve the convenience and stability of assembly, a positioning protrusion 138 is provided on the connecting portion 135, and positioning holes 114 are provided on both the first housing 111 and the second housing 121. The positioning protrusion 138 is inserted into the positioning hole 114. Specifically, the positioning protrusion 138 is fixed on the base body 136 and is on the same side of the base body 136 as the buckle 137. The positioning protrusion 138 and the buckle 137 are spaced apart, and the buckle 137 is located on the side of the connecting portion 135 away from the outer sheath 131. Through the cooperation form of the spaced positioning protrusion 138 and the buckle 137, on the one hand, the alignment of the connecting bridge 130 with the first housing 111 and the second housing 121 is more convenient, and on the other hand, after connection, with two positions for limiting, the connection is more firm and it is not easy to loosen.

[0054] In one embodiment, mounting grooves 115 are provided on the outer surfaces of both the first housing 111 and the second housing 121, and a connecting portion 135 is correspondingly disposed in one mounting groove 115. The above-mentioned card connection groove 113 is formed on the groove wall of the mounting groove 115. The setting of the mounting groove 115 can accommodate at least part of the structure of the connecting portion 135 therein. Thus, it is beneficial to achieve close contact between the outer sheath 131 of the connecting bridge 130 and the first housing 111 and the second housing 121, thereby reducing the size of the gap between the outer sheath 131 and the first housing 111 and the second housing 121 and improving the sealing performance.

[0055] Two connecting portions 135 of the present application are respectively provided with wire outlet ports 139, and the wire outlet ports 139 communicate with the wire routing channels 134. The first housing 111 is provided with a first wire passing port, and the second housing 121 is provided with a second wire passing port. Then, one end of the electrical connector 140 passes through the wire outlet port 139 and enters the first housing 111 through the first wire passing port and is connected to the first electrical component. The other end of the electrical connector 140 passes through the wire outlet port 139 and is electrically connected to the second electrical component through the second wire passing port. Further, the first wire passing port and the second wire passing port can share the above-mentioned card connection groove 113 or be separately provided. The positioning protrusions 138 provided on the connecting portion 135 can be two spaced apart, and the wire outlet ports 139 on each connecting portion 135 can be respectively provided between the two positioning protrusions 138. With such a setting, during the threading process of the electrical connector 140, the positioning protrusions 138 can also limit and guide the electrical connector 140.

[0056] Since the connecting portion 135 of the present application is provided on the side of the outer sheath 131 facing the wearing space 150, after assembly, the connecting portion 135 is basically hidden in the above-mentioned mounting groove 115. At this time, the wire outlet port 139 is covered by the first housing 111 and is not exposed, and the wire outlet port 139 is covered by the second housing 121 and is not exposed. With such a setting, the entire electrical connector 140 is a hidden design, and the sealing performance is better.

[0057] It should be noted that for the detachable connection forms of both ends of the connection bridge 130 or the outer sheath 131 to the first housing 111 and the second housing 121 respectively, in addition to the forms exemplified above, the above-mentioned connection portion 135 may not be provided, that is, the outer sheath 131 is directly connected. And for the specific connection form, in addition to snap connection, it may also be threaded connection, plug connection, magnetic connection, etc. The present application does not limit this.

[0058] During the production and assembly process of the open earphone of the present application, the threading operation can be performed on the connection bridge 130 alone. For example, a traction belt may be adhered to one end of the electrical connector 140. The traction belt can be made of a soft PET (polyethylene terephthalate) sheet. By utilizing the deformation ability and toughness of the traction belt, after passing through the two wire outlet ports 139, the electrical connector 140 is further passed through the wire routing channel 134. In this way, while realizing a quick threading operation, the structural integrity of the electrical connector 140 can be ensured as much as possible, thereby improving the product yield.
