Description

Technical Field

[0001] This utility model relates to the field of electronic accessories, specifically to a wireless earphone. Background Technology

[0002] Wireless headphones are audio transmission devices that use wireless transmission methods such as Bluetooth to transmit signals to signal output terminals such as computers and mobile phones.

[0003] Some wireless earphones designed for outdoor sports use a clip-on design, with an ear clip connecting arm attached to one side of the earphone body. This arm clamps onto the wearer's ear, securing the earphone in place. Existing ear clips are generally made of rigid, elastic, or plastic materials. Rigid and elastic clips tend to have a fixed shape or tend to revert to that shape, making it difficult to fit all ear shapes and resulting in poor comfort and stability. Plastic clips, on the other hand, are inconvenient because wearers often have to operate them with only one hand, making it difficult to control deformation under pressure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a wireless earphone, comprising:

[0005] The first compartment is equipped with an acoustic module and a sound transmission port.

[0006] The connector is made of a plastic material and includes a first end and a second end, wherein the first end is connected to the first compartment.

[0007] The connector has a deformation threshold, which enables it to deform under a force higher than the deformation threshold and to maintain its original shape under a force lower than the deformation threshold. The deformation threshold gradually increases from the middle of the connector toward the first end and the second end.

[0008] Preferably, the cross-sectional area of ​​the connector gradually increases from the middle towards the first end and the second end.

[0009] Preferably, it further includes a second compartment, in which a battery is installed, the second compartment is connected to the second end, and a wire harness is provided in the connecting body, the second compartment and the first compartment being electrically connected through the wire harness.

[0010] Preferably, the surface of the connector is provided with a wiring groove for arranging the wire bundle.

[0011] Preferably, the wire harness is an FPC flexible circuit board, and a protective cover is detachably provided on the wiring channel; wherein, when the protective cover is removed, the channel body of the wiring channel is exposed to the outside to facilitate the installation of the FPC flexible circuit board; when the protective cover is installed, the FPC flexible circuit board is located in the space enclosed by the wiring channel and the protective cover.

[0012] Preferably, the material of the connector is shape memory metal. The shape memory metal shell of the connector is connected to the mainboard inside the earphone through the FPC flexible circuit board. The shape memory metal shell of the connector can serve as a signal transceiver element. The mainboard can transmit signals to an external terminal through the FPC flexible circuit board and the connector.

[0013] Preferably, a sealing structure is provided between the connecting body and the first compartment and the second compartment.

[0014] Preferably, the surface of the connector is covered with a first bonding layer, which is made of a flexible material.

[0015] Preferably, the connector has an initial shape, which is a "C" shape.

[0016] Preferably, the connector is provided with an elastic protective member that conforms to the outer contour of the connector, and when the connector is in the initial shape, the elastic force inside the elastic protective member is zero.

[0017] The wireless earphone provided by this utility model includes a first housing and a connector. The first housing is used to install components such as an acoustic module, and the connector is used to fix the wireless earphone to the wearer's ear. The connector is made of a plastic material that can deform under force above the deformation threshold and maintain its original shape under force below the deformation threshold. By applying force to the connector, its first end (first housing) and second end can be clamped in the wearer's auricle. The deformation threshold of the connector gradually increases from the middle to both ends. Therefore, when the wearer puts the first housing of the wireless earphone into the ear canal and applies force to the second end to adjust the shape of the connector, the deformation of the connector mainly occurs in the middle, and the deformation at both ends is small. That is, the two ends of the first and second ends are in a relatively stable state, which makes it easier for the wearer to operate the first end (first housing) and the second end to fix it in the auricle. During the wearing process, the first end and the second end can maintain a stable fit with the auricle, which can improve the wearing comfort and stability. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Figure 1 This is a schematic diagram of the overall structure of a wireless earphone provided in an embodiment of the present invention.

[0024] like Figure 1 As shown, this utility model provides a wireless earphone, including a first housing 1 and a connector 2. The first housing 1 is provided with an acoustic module and a sound transmission port (not shown in the figure) for receiving signals from external terminal devices and converting audio signals into sound waves that are transmitted from the sound transmission port. The connector 2 is made of plastic material and has a first end 21 and a second end 22. The first end 21 is connected to the first housing 1. The connector 2 has a deformation threshold, which allows it to deform under a force higher than the deformation threshold and to maintain its original shape under a force lower than the deformation threshold.

[0025] When the wearer wears the wireless earphone, the first housing 1 is first installed on the outside of the ear canal. Then, force is applied to the connector 2 to cause plastic deformation of the connector 2, and the first end 21 (first housing 1) and the second end 22 of the connector 2 are clamped in the wearer's auricle.

[0026] Furthermore, the deformation threshold gradually increases from the middle of the connector 2 towards both ends. On the one hand, when the connector 2 is subjected to overall force, its main deformation occurs in the middle, while the deformation at both ends is relatively small. That is, the two ends, the first end 21 and the second end 22, are in a relatively stable state, making it easier for the wearer to operate the first end 21 and the second end 22 to fix it to the auricle. Moreover, during long-term wear after adjustment, the first end 21 and the second end 22 can maintain a stable fit with the auricle, which can improve the comfort and stability of wearing. On the other hand, the deformation threshold at the connection between the first end 21 and the first housing 1 is relatively high, which can reduce the deformation amplitude of the connection between the first end 21 and the first housing 1 and enhance the connection stability between the first end 21 and the first housing 1.

[0027] The first chamber 1 contains an acoustic module and a sound transmission port, which are very mature technologies in existing wireless or wired headphones. In practical applications, the specific shape of the first chamber 1 and the specific location of the sound transmission port can be adaptively adjusted according to the specific specifications of the connector 2, which will not be elaborated here.

[0028] In addition, in order to further improve the stability of the connection between the first end 21 and the first compartment 1, a rigid section can be provided at the connection between the first end 21 and the first compartment 1 so that the connection between the first end 21 and the first compartment 1 will not deform.

[0029] Figure 2 This is a schematic diagram of the structure of the connector of a wireless earphone provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the connector of a wireless earphone provided in one embodiment of the present invention from another perspective.

[0030] like Figure 2 and Figure 3 As shown, the cross-sectional area of ​​the connector 2 gradually increases from the middle towards the first end 21 and the second end 22, thereby achieving a gradual increase in the deformation threshold from the middle to both ends of the connector 2. This can be achieved in... Figure 3 The vertical width of the connecting body 2 shown gradually increases from the middle to both ends. Alternatively, the connecting body 2 may be located at... Figure 3 The width of the connector 2 in the direction perpendicular to the paper gradually increases from the middle to both ends. In this way, the deformation threshold of the connector 2 can be gradually increased from the middle to both ends. Alternatively, the deformation threshold of the connector 2 can be gradually increased from the middle to both ends by controlling the difference in material density or material properties between the middle and both ends of the connector 2, or by processing a degaussing hole or degaussing groove in the middle of the connector 2 so that the amount of material in the middle of the connector 2 is less than that at both ends.

[0031] It should be noted that the cross-sectional area mentioned above is the effective area of ​​the connecting body 2 on the cross section, not the area of ​​the outline enclosed by the outer edge of the connecting body 2 on the cross section. For example, when the connecting body 2 is a hollow structure, only the solid area of ​​the annular shape formed by the connecting body 2 on the cross section should be considered, and the cross-sectional area should not be considered to include the area of ​​the hollow part.

[0032] like Figure 1 As shown, in one preferred embodiment, a second compartment 3 connected to the second end 22 is further included. The second compartment 3 may be... Figure 1 The shape shown is exactly the same as the first compartment 1, but it can also be other shapes suitable for clamping the auricle. The second compartment 3 can be used to install auxiliary components such as batteries and signal receivers, which can simplify the electrical structure inside the first compartment 1. A wire harness is provided inside the connector 2, and the second compartment 3 and the first compartment 1 are electrically connected through the wire harness.

[0033] In one preferred embodiment, the outer surfaces of the first cavity 1 and the second cavity 3 are continuously transitioning arc-shaped or spherical surfaces. When the wearer operates the first end 21 and the second end 22 of the connector 2 to adjust the shape of the connector 2, the smooth outer surfaces of the first cavity 1 and the second cavity 3 that fit against the wearer's ear can improve the wearing comfort.

[0034] Furthermore, a second fitting layer can be provided on the first chamber 1 and the second chamber 3. The second fitting layer is located in the parts of the first chamber 1 and the second chamber 3 that are frequently in contact with the wearer's skin. After being held in the ear by the first chamber 1, the connector 2 and the second chamber 3, the wearer will not feel uncomfortable even after wearing it for a long time, thus further improving comfort.

[0035] like Figure 2 and Figure 3 As shown, in one preferred embodiment, a wiring groove 23 is provided on the surface of the connector 2 for the arrangement of the wire harness. By setting the wiring groove 23, when installing the wireless earphone, after the first compartment 1 and the second compartment 3 are electrically connected and installed, the connector 2 can be directly connected between the first compartment 1 and the second compartment 3, and the wire harness can be directly arranged in the wiring groove 23. Compared with the original method of setting the wiring groove inside the ear clip connecting arm and then having to run the wire through the ear clip connecting arm, this simplifies the installation and manufacturing process of the wireless earphone and improves production efficiency.

[0036] Furthermore, based on the above settings, a removable protective cover (not shown in the figure) can also be installed on the wiring channel 23. When the protective cover is not installed, the wiring channel 23 is... Figure 2The groove shown is completely exposed to the outside world. In this way, the wires can also use FPC flexible circuit boards. FPC flexible circuit boards have high signal transmission efficiency, but they are relatively soft. By setting the groove of the wiring groove 23 to be completely exposed to the outside world, the middle structure of the FPC flexible circuit board can be directly arranged in the wiring groove 23. Then, a protective cover is installed on the wiring groove 23, which can play a good role in protecting the FPC flexible circuit board inside. Then, the FPC flexible circuit board can be connected to the first housing 1 and the second housing 3 of the earphone.

[0037] It should also be noted that the protective cover should be made of a similar plastic material to the connector 2 to ensure that the plastic deformation function of the connector 2 can be smoothly realized. The protective cover and the wiring groove 23 can be connected by a snap-fit ​​mechanism or by screws for detachable connection. A sealing gasket is also provided between the protective cover and the wiring groove 23 to improve the protection of the FPC flexible circuit board. In some other embodiments, the protective cover and the wiring groove 23 can be bonded with a pyrolytic adhesive, which has good bonding strength and good sealing performance at room temperature. When it is necessary to remove the protective cover, the pyrolytic adhesive is heated to make it lose its stickiness, so as to facilitate the removal.

[0038] In one preferred embodiment, a sealing structure is provided between the connector 2 and the first chamber 1 and the second chamber 3. This serves two purposes: firstly, it protects the electrical components inside the first chamber 1 and the second chamber 3 from external liquids or dust entering the chambers; secondly, it enhances the connection strength between the connector 2 and the first chamber 1 and the second chamber 3. The sealing structure can be installed between the connector 2 and the chambers using injection molding sealant or injection molding plastic, etc., which will not be elaborated here.

[0039] In one preferred embodiment, the material of the connector 2 is a shape memory metal, specifically a nickel-titanium alloy or an iron-based shape memory alloy. Shape memory metals can undergo reversible deformation under certain external forces, and have good recovery force and comfort, making them particularly suitable for applications in this application where the connector 2 needs to be repeatedly bent and adjusted in shape.

[0040] Furthermore, leveraging the metallic properties of connector 2, it can be extended into a headphone communication antenna. Its metallic body can sense and receive signals from all directions. The shape-memory metal shell of connector 2 is connected to the mainboard inside the headphone via a flexible printed circuit board (FPC), thereby transmitting the received signals to the headphone's mainboard and other corresponding processing modules. This allows the mainboard to transmit signals to external terminals via the FPC and connector 2. This large antenna significantly enhances the headphone's wireless communication capabilities while eliminating the need for internal signal receiving components within the headphone.

[0041] Connector 2 can also be made of other plastic materials according to actual cost control needs, such as aluminum alloys or organic polymer materials with excellent ductility.

[0042] In one preferred embodiment, the surface of the connector 2 is covered with a first adhesive layer, which is made of a flexible material, such as silicone or rubber. By covering the surface of the connector 2 with the first adhesive layer, the comfort of the connector 2 when in contact with the auricle can be improved. In addition, when the cross-sectional area of ​​the connector 2 gradually increases from the middle to the first end 21 and the second end 22, the connector 2 and the first adhesive layer can be made into a uniform shape by covering and filling the first adhesive layer, thereby improving the aesthetics of the wireless earphone.

[0043] In one preferred embodiment, the connector 2 has an initial state in which its shape is "C", that is... Figures 1 to 3 The single-sided opening shape shown allows the connector 2 to form an ear clip shape in its initial state. The first end 21 and the second end 22 can be clamped on both sides of the wearer's ear. When the wearer actually wears and adjusts the connector 2, the amount of deformation of the connector 2 that needs to be adjusted is small, thereby reducing the amount of deformation of the connector 2 when the wireless headphones are in use, as well as the operations that the wearer needs to perform when wearing the headphones.

[0044] In one preferred embodiment, the connector 2 is provided with an elastic protective member. The elastic protective member can conform to the outer contour of the connector 2. When the connector 2 is in the initial shape described above, the elastic force inside the elastic protective member is zero. Therefore, when the shape of the connector 2 is finely adjusted, the elastic resistance generated by the elastic protective member is small, so that the fine adjustment of the connector 2 can be carried out smoothly. When the deformation of the connector 2 is large, the elastic protective member can generate a strong elastic resistance to prevent the connector 2 from undergoing large deformation. When the connector 2 is subjected to accidental situations such as collision, compression or pulling, the resistance of the elastic protective member plays a good protective role for the connector 2.

[0045] The elastic protective element can be a spring or other elastic element fitted on the connector 2, or the first bonding layer mentioned above can be used as the elastic protective element. For example, a rubber material with good compressibility and good elasticity can be used as the first bonding layer, which can serve as an elastic contact between the outer surface of the connector 2 and the wearer's auricle, and can also serve as an elastic protective element to protect the connector 2.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions to the technical solution of this utility model do not depart from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered by the claims of this utility model.
