Description

[Technical Field]

[0001] The present application relates to the technical field of earphones, and more particularly to open-type earphones. [Background technology]

[0002] Open-type earphones are earphones that do not need to be inserted deep into the ear canal, allowing users to enjoy music or calls while maintaining awareness of the surrounding environment. Among open-type earphones, ear-hook and ear-cuff types are two common design forms, with ear-hook types securing the earphone above the ear and supported by a frame that surrounds the ear, providing stability and comfort, while open-type earphones are secured by being clipped onto the auricle.

[0003] As for the open-type earphone, it usually includes two chambers and a connecting bridge connecting the two chambers, and a speaker and a battery are respectively installed in one chamber, so that the open-type earphone usually needs to install wiring to connect the speaker and the battery located in the two chambers.

[0004] In related art, when the wiring passes through the connecting bridge, in-mold injection molding is mainly used, and only two injection moldings are performed to complete the complete coverage of the wiring on the connecting bridge. During injection molding, the shape of the wiring cannot be well controlled, which makes it easy for breakage to occur, resulting in the entire injection molded product being scrapped and resulting in high costs. Summary of the Invention [Problem to be solved by the invention]

[0005] The embodiments of the present application provide open-type earphones that can improve the product yield and reduce production costs. [Means for solving the problem]

[0006] In a first aspect, an open-type earphone according to an embodiment of the present application includes a sound-generating member, a fixing member, a connecting bridge, and an electrical connection member, the sound-generating member including a first housing and a first electrical component installed in the first housing, the fixing member including a second housing and a second electrical component installed in the second housing, both ends of the connecting bridge being connected to the first housing and the second housing, respectively, a wiring passage being installed in the connecting bridge, and the electrical connection member being movably inserted through the wiring passage, one end being inserted into the first housing and electrically connected to the first electrical component, and the other end being inserted into the second housing and electrically connected to the second electrical component.

[0007] In the open-type earphones according to the embodiments of the present application, a wiring passage is provided in the connecting bridge, and the electrical connection member is inserted into the wiring passage, thereby realizing the electrical connection between the first and second electrical components in the two housings. Due to the design of the wiring passage, the electrical connection member passes through the wiring passage in the later stage of the assembly and production process, thereby achieving a hidden arrangement for the electrical connection member. This eliminates the need to assemble the electrical connection member to the connecting bridge using the production method of multiple injection moldings as in the conventional production method. As a result, the electrical connection member is not properly fixed during the injection molding production process, resulting in misalignment. This can avoid damage caused by high temperatures, thereby improving the production yield of open-type earphones and reducing production costs. The advantage of this design is that the electrical connection member of the present application is movably inserted into the wiring passage, so that even if the connection bridge is bent during the process of wearing the open-type earphone, the electrical connection member can be adjusted adaptively within the wiring passage, effectively reducing the risk of the electrical connection member being broken. In the later use process, if the electrical connection member is damaged, it can be easily replaced, and the service life of the open-type earphone can be extended.

[0010] The achievement of the object, functional features and advantages of the present invention will be further explained in combination with examples with reference to the drawings. DETAILED DESCRIPTION OF THE INVENTION

[0011] In order to make the objectives, technical means and advantages of the present application clearer, the embodiments of the present application will be described in more detail below with reference to the drawings.

[0012] In the following description, when referring to the drawings, the same numbers in different drawings refer to the same or similar elements unless otherwise stated. The embodiments described in the following illustrative examples are not representative of all embodiments consistent with the present application. On the contrary, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Those skilled in the art can understand the specific meaning of the above terms in the description of this application according to the specific circumstances.

[0014] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. Terms used herein are for the purpose of describing specific examples only and are not intended to limit the scope of this application. As used herein, the term "and / or" includes any and all combinations of one or more associated items.

[0015] Earphones, as commonly used electronic products, play an important role in people's lives. They receive electrical signals transmitted by a media player or receiver and convert them into visible sound waves through speakers placed close to the ear, allowing users to listen independently without disturbing others and isolating the surrounding environment, making them useful for people who use earphones in noisy environments such as recording studios, DJ sets, traveling, and exercise. When classified by their sound generation mechanism, earphones include air conduction earphones and bone conduction earphones. When classified by wearing method, earphones include headphones, ear-hook earphones, and open earphones.

[0016] Open earphones are earphones that do not need to be inserted into the ear canal, allowing users to enjoy music or calls while maintaining awareness of the surrounding environment. Among open earphones, ear-hook and ear-cuff designs are two common designs, with ear-hook designs securing the earphone above the ear and supported by a frame that surrounds the ear, providing stability and comfort, while open earphones are secured by being clipped onto the auricle.

[0017] As for the open-type earphone, it usually includes two chambers and a connecting bridge connecting the two chambers, and a speaker and a battery are respectively installed in one chamber, so that the open-type earphone usually needs to install wiring to connect the speaker and the battery located in the two chambers.

[0018] In related art, when the wiring passes through the connecting bridge, in-mold injection molding is mainly used, and only two injection moldings are performed to complete the complete coverage of the wiring on the connecting bridge. During injection molding, the shape of the wiring cannot be well controlled, which makes it easy for breakage to occur, resulting in the entire injection molded product being scrapped and resulting in high costs.

[0019] To solve the above problems, embodiments of the present application provide open earphones, which may be communicatively connected to devices such as mobile phones, computers, MP3 players, and wearable audio devices.

[0020] 1 to 3, in the solutions exemplarily shown in Fig. 1 to 3, the open-type earphone 10 is shown as an ear cuff-type earphone as an example. In the embodiment of the present application, the open-type earphone 10 includes a sound-generating member 110, a fixing member 120, a connecting bridge 130, and an electrical connecting member 140, and both ends of the connecting bridge 130 are respectively connected to the sound-generating member 110 and the fixing member 120. The connecting bridge 130 may be curved. For example, if the open-type earphone 10 is an ear cuff-type earphone, the connecting bridge 130 may be C-shaped or U-shaped. In an ear-hook-type earphone, the connecting bridge 130 has an arc-shaped structure curved around the user's ear. The sound-generating member 110, the connecting bridge 130 and the fixing member 120 cooperate to form the wearing space 150, and the connecting bridge 130 provides an elastic clamping force during the process of wearing the earphone. Specifically, the sound-generating member 110 abuts against the front of the user's ear, and the fixing member 120 is located on the back of the user's ear, which is located within the wearing space 150, and the sound-generating member 110 and the fixing member 120 cooperate to clamp the user's ear.

[0021] When the open-type earphone 10 is an ear-hook type earphone, the connecting bridge 130 is generally hook-shaped and extends to the back of the user's ear to be hooked onto the ear; similarly, the sound-generating member 110 is located in front of the ear, and the fixing member 120 is located at the back of the ear. The difference from the ear-cuff type earphone is that the connecting bridge 130 is not primarily for providing clamping force during the wearing process.

[0022] The sound-generating member 110 includes a first housing 111 and a first electrical component (not shown) installed within the first housing 111. The first housing 111 has an ellipsoidal, flat structure, or the like, and may be made of a material such as plastic or silicone. For example, the inner wall may be made of hard plastic, and the outer surface may be covered with a soft material layer such as silicone, to improve the feel. The first housing 111 has a sound output hole 112, and the first electrical component may be a speaker alone. During use, sound emitted by the speaker alone passes through the sound output hole 112 and the user's ear canal opening and enters the user's ear canal. Note that, during wearing, the open-type earphone 10 of the present application has the sound-generating member 110 not entering the ear canal, and the sound output hole 112 faces the user's ear canal opening.

[0023] The fixing member 120 includes a second housing 121 and a second electrical component (not shown) installed in the second housing 121. As can be understood, the open-type earphone 10 further includes a control circuit board and a battery, and the control circuit board may be installed in the first housing 111 together with the speaker alone, or in the second housing 121 together with the battery. Thus, the electrical connection member 140 of the present application may be electrically connected to the battery and the control circuit board, or to the speaker alone and the control circuit board. That is, the first electrical component of the present application may be the control circuit board or the speaker alone, and the second electrical component may be the battery or the control circuit board, and the battery may be in the form of a rechargeable lithium battery, which supplies power to the control circuit board and the speaker alone during operation.

[0024] Regardless of whether the control circuit board is installed in the first housing 111 or the second housing 121, the open-type earphone 10 of the present application needs to be electrically connected to the electronic elements in the first housing 111 and the second housing 121, and thus the electrical connection member 140 needs to pass through the connection bridge 130 to achieve electrical continuity between the first electrical component and the second electrical component. It can be understood that in actual operation, the speaker unit and the battery are both connected to the control circuit board, and the control circuit board provides power and control signals to the speaker unit. Therefore, in one installation mode, 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 is installed in the second housing 121 together with the battery, the electrical connection member 140 is physically connected to the speaker unit and the control circuit board, and transmits power and control signals from the control circuit board to the speaker unit, thereby realizing the normal sound output function of the speaker unit.

[0025] 4, to realize the arrangement of the electrical connection member 140, a wiring passage 134 is further installed in the connecting bridge 130 in the present application. The electrical connection member 140 is movably inserted through the wiring passage 134, with one end inserted into the first housing 111 and electrically connected to the first electrical component, and the other end inserted into the second housing 121 and electrically connected to the second electrical component. Furthermore, in the solution of the present application, the electrical connection member 140 is movable along the length of the wiring passage 134, thereby facilitating wiring operations. Specifically, the electrical connection member 140 is retractable relative to the inner wall of the wiring passage 134.

[0026] In the open-type earphone 10 according to the embodiment of the present application, a wiring passage 134 is provided in the connecting bridge 130, and the electrical connection member 140 is inserted into the wiring passage 134, thereby realizing an electrical connection between the first and second electrical components in the two housings. Due to the design of the wiring passage 134, the electrical connection member 140 passes through the wiring passage 134 in the later stage of the assembly and production process, thereby achieving a hidden arrangement for the electrical connection member 140. This eliminates the need to assemble the electrical connection member 140 to the connecting bridge 130 using the production method of multiple injection moldings as in the conventional production method. This reduces the risk of the electrical connection member 140 not being properly fixed during the injection molding production process. This prevents the open-type earphone 10 from being damaged by slippage or high temperatures, thereby improving the production yield and reducing production costs. Another advantage of this design is that the electrical connection member 140 of the present application is movably inserted into the wiring passage 134. Therefore, even if the connecting bridge 130 is bent during the process of wearing the open-type earphone, the electrical connection member 140 can be adjusted adaptively within the wiring passage 134, which effectively reduces the risk of the electrical connection member 140 being broken. If the electrical connection member 140 is damaged during later use, it can be easily replaced, and the service life of the open-type earphone 10 can be extended.

[0027] In one embodiment, the connecting bridge 130 includes an outer casing 131 and a shape memory metal member 132, the shape memory metal member 132 is housed in the outer casing 131, both ends of the outer casing 131 are connected to the first housing 111 and the second housing 121 respectively, and a wiring passage 134 is installed in the outer casing 131.

[0028] The outer jacket 131 is made of a material having a certain degree of elasticity, such as plastic or silicone. The shape memory metal member 132 may be a titanium wire, which is elongated and extends along the length of the outer jacket 131. The shape memory metal member 132 is covered by the outer jacket 131, thereby allowing the connecting bridge 130 to have excellent deformation recovery ability. During the production process, the shape memory metal member 132 may be fixed integrally with the outer jacket 131 in a pre-embedded form. The wire passage 134 may be molded together with the outer jacket 131 during molding. In one embodiment, a temporary wire is used to be pre-embedded in injection molding together with the outer jacket 131. After injection molding, the temporary wire is removed from the material of the outer jacket 131, and the original position of the temporary wire forms the wire passage 134.

[0029] The shape memory metal member 132 and the wire passage 134 of the present invention extend parallel to each other in the longitudinal direction of the outer jacket 131. The wire passage 134 and the shape memory metal member 132 are spaced apart from each other, and the arc degree of the wire passage 134 is equal to that of the shape memory metal member 132. Thus, during the bending deformation of the entire connecting bridge 130, the electrical connection member 140 can move freely within the wire passage 134, thereby preventing the electrical connection member 140 from being broken.

[0030] As can be understood, in other embodiments, the connecting bridge 130 of the present application may not be provided with the shape memory metal member 132, but may be composed of only the outer shell 131, and the outer shell 131 may be selected from materials having a certain elastic recovery ability, such as plastic, silicone, metal, etc., and the present application is not limited thereto.

[0031] As shown in FIGS. 2 and 3, the outer jacket 131 includes an outer jacket main body 1311 and an outer jacket cover 1312, and the outer jacket cover 1312 is engaged with the outer jacket main body 1311, and a wire passage 134 is formed between the outer jacket main body 1311 and the outer jacket cover 1312.

[0032] The electrical connection member 140 has a plate-like structure portion or a wave-like structure portion within the wiring passage 134, and the shape of the wiring passage 134 is adapted to the shape of the electrical connection member 140. By being installed in this manner, the electrical connection member 140 maintains a stable posture during the wiring process and does not twist, thereby making the wiring process smoother.

[0033] In one installation form, the electrical connection member 140 includes a first bent portion 142, a main body portion 141 and a second bent portion 143 connected in sequence, the main body portion 141 extending into the wiring passage 134, the first bent portion 142 bending and extending into the first housing 111 and electrically connecting to the first electrical component, and the second bent portion 143 bending and extending into the second housing 121 and electrically connecting to the second electrical component.

[0034] During actual use of the open-type earphone 10 of this embodiment, when the connecting bridge 130 is bent, it will further stretch the electrical connecting member 140. The electrical connecting member 140 has a first bent portion 142 and a second bent portion 143, which provide the entire electrical connecting member 140 with more stretching momentum. Thus, during bending of the connecting bridge 130, neither the connecting portion between the electrical connecting member 140 and the first electrical component nor the connecting portion between the electrical connecting member 140 and the second electrical component will be stretched. This effectively ensures conductive contact and improves the overall operational stability of the open-type earphone 10.

[0035] Furthermore, the first bending portion 142 is bent around the first electrical component along a first bending direction, and the second bending portion 143 is bent around the second electrical component along a second bending direction, the first bending direction being different from the second bending direction.

[0036] 2 to 4, the first bent portion 142 bends and extends around the side opposite the connecting bridge 130 of the first electrical component, and the second bent portion 143 bends and extends around the side opposite the connecting bridge 130 of the second electrical component. This arrangement allows for a rational layout of the wires, and allows for the use of relatively short wires, ensuring that the connecting bridge 130 has as much extension momentum as possible during the bending deformation process, thereby effectively reducing the phenomenon of tension being applied to the welded connection portion of the electrical connection member 140 and improving the stability of the connection.

[0037] Furthermore, the main body 141 may have a plate-like structure or a wave-like structure. When the main body 141 has a plate-like structure, the thickness direction of the main body 141 is arranged to coincide with the thickness direction of the connecting bridge 130. As shown in FIG. 2, H in the figure indicates the thickness direction of the connecting bridge 130. This arrangement ensures that the deformation direction of the main body 141 is the same as that of the connecting bridge 130 during the bending deformation process, thereby effectively reducing the risk of damage to the main body 141 due to stress concentration. When the main body 141 has a wave-like structure, a larger amount of kinetic deformation is applied during the entire drawing process of the electrical connection member 140, thereby reducing the risk of damage to the connecting bridge 130 during the bending deformation process of the electrical connection member 140 and the resulting loosening of the electrically welded portions due to tension.

[0038] In one embodiment, the electrical connection member 140 may be in the form of a flexible printed circuit (FPC), thereby achieving power and signal transmission for the first electrical component using a smaller amount of wire. When the flexible printed circuit has a wave-shaped structure, the flexible printed circuit has a greater deformation capacity during the bending deformation of the connection bridge 130, making it less susceptible to damage and breakage, and thus extending its service life. It should be understood that the electrical connection member 140 of the present application may also be in the form of other wires, such as multiple single-core cables, multi-core cables, etc., and the present application is not limited thereto.

[0039] In the present application, the outer casing 131 may have one end detachably connected to the first housing 111 and the other end fixedly connected to the second housing 121. In this case, in order to achieve high wiring efficiency during the production process, the second housing 121 may be installed in a form in which it is joined by a plurality of sub-housings installed separately, one of which is fixedly connected to the outer casing 131. In this way, wiring is performed in an open state of the second housing 121. Naturally, the outer casing 131 may have one end fixedly connected to the first housing 111 and the other end detachably connected to the second housing 121. This type of wiring process is similar to the above content, and therefore, description thereof will be omitted here.

[0040] In addition, in the present application, both ends of the outer jacket 131 may be detachably connected to the first housing 111 and the second housing 121, respectively. By installing in this manner, the electrical connection member 140 passes through the connection bridge 130 before being assembled with the first housing 111 and the second housing 121, thereby achieving modular assembly and thus significantly improving production efficiency. Also, during later maintenance, it is easy to remove the connection bridge 130 and perform wiring operations.

[0041] As shown in FIGS. 5 to 8, in one specific detachable connection form, both ends of the outer jacket 131 may be locked to the first housing 111 and the second housing 121, respectively.

[0042] Specifically, in one installation style, the open-type earphone 10 of the present application has connecting portions 135 installed on both ends of the outer cover 131, the outer cover 131 installed in an arc shape, the two connecting portions 135 connected to both ends of the outer cover 131, the shape memory metal member 132 extending inside the outer cover 131, and both ends of the shape memory metal member 132 inserted into a corresponding connecting portion 135. A snap fitting 137 is installed on the connecting portion 135, and a locking through-groove 113 is installed on both the first housing 111 and the second housing 121, and the snap fitting 137 is locked into the locking through-groove 113.

[0043] In this embodiment, connecting portions 135 are provided on both ends of the outer jacket 131, and the hardness of the connecting portions 135 is greater than that of the outer jacket 131. The two are molded into an integral structure by secondary injection molding, or are fixed together by adhesive, hot melt, etc. In this way, the outer jacket 131 mainly functions to generate a repulsive force through deformation, and the connecting portions 135 perform a connecting function. The connection by the connecting portions 135 having greater hardness makes the connection stronger. The connecting portions 135 and the first and second housings 111, 121 are interlocked, which requires fewer tools during the assembly process and makes attachment and detachment easier.

[0044] Specifically, the connection part 135 includes a base 136, and the snap fit 137 is connected to the base 136 and has a cross section that is approximately shaped like a letter "7". The snap fit 137 protrudes from one side of the base 136. In this way, a position limiting groove is formed between the snap fit 137 and the base 136 in cooperation with each other. During the assembly process, the snap fit 137 passes through the locking through groove 113 and fits the wall of the first housing 111 into the position limiting groove, and the hook part of the snap fit 137 abuts against the inner wall of the first housing 111, thus realizing the relative fixation of the connection part 135 and the first housing 111.

[0045] Furthermore, to improve the convenience and stability of assembly, a positioning protrusion 138 is further provided on the connecting portion 135, and positioning holes 114 are provided on both the first housing 111 and the second housing 121, and the positioning protrusion 138 is inserted into the positioning holes 114. Specifically, the positioning protrusion 138 is fixed to the base 136 and is located on the same side of the base 136 as the snap fitting 137, with a gap between the positioning protrusion 138 and the snap fitting 137, and the snap fitting 137 is located on the side of the connecting portion 135 away from the outer casing 131, with a gap between the positioning protrusion 138 and the snap fitting 137. This engagement type makes it easier to align the connecting bridge 130 with the first housing 111 and the second housing 121, and after connection, the two positional restrictions make the connection stronger and less likely to come off.

[0046] In one embodiment, the first housing 111 and the second housing 121 each have a mounting groove 115 on their outer surfaces, one of the connection parts 135 is correspondingly installed in one of the mounting grooves 115, and the above-mentioned locking through-groove 113 is formed in the groove wall of the mounting groove 115. By installing the mounting groove 115, at least a part of the structure of the connection part 135 is accommodated in the mounting groove 115, which helps to achieve close contact between the outer shell 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 shell 131 and the first housing 111 and the second housing 121 and improving the sealing performance.

[0047] The two connection parts 135 of the present application are each provided with a wire outlet 139, which is connected to the wire passage 134, the first housing 111 is provided with a first wire passage opening, and the second housing 121 is provided with a second wire passage opening, and one end of the electrical connection member 140 passes through the wire outlet 139 and then the first wire passage opening to enter the first housing 111 and be connected to the first electrical component, and the other end passes through the wire outlet 139 and then the second wire passage opening to be electrically connected to the second electrical component. Furthermore, the first wire passage opening and the second wire passage opening may be used in conjunction with the locking through-hole 113 or may be provided separately. In the above, the positioning protrusions 138 installed on the connection portion 135 may be two that are installed at a distance from each other, and the wire outlets 139 of each connection portion 135 may be installed between the two positioning protrusions 138, respectively. When installed in this manner, the positioning protrusions 138 can limit and guide the position of the electrical connection member 140 during the insertion process of the electrical connection member 140.

[0048] Since the connection portion 135 of the present invention is installed on the side of the outer casing 131 facing the mounting space 150, after assembly, the connection portion 135 is substantially hidden within the mounting groove 115, and in this case, the wire outlet 139 is covered by the first housing 111 and not exposed, and the wire outlet 139 is covered by the second housing 121 and not exposed. By installing in this manner, the entire electrical connection member 140 has a hidden design and is more sealed.

[0049] In addition to the above-mentioned examples, in the case where both ends of the connecting bridge 130 or the outer casing 131 are removably connected to the first housing 111 and the second housing 121, the connecting portion 135 may not be installed, that is, the outer casing 131 may be directly connected, and the specific connection form may be, in addition to locking, screwing, insertion, magnetic connection, etc., and the present application does not limit this.

[0050] During the production and assembly process of the open-type earphone of the present application, the wiring operation can be performed separately on the connecting bridge 130. For example, a traction band can be attached to one end of the electrical connection member 140. The traction band can be made of a soft PET (polyethylene terephthalate) sheet. By utilizing the deformation ability and toughness of the traction band, the electrical connection member 140 can be passed through the wiring passage 134 after passing through the two wire outlets 139, thereby realizing a quick wiring operation and ensuring the structural integrity of the electrical connection member 140 as much as possible, thereby improving the product yield.
