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

[0003] Some wireless earphones suitable for outdoor sports and other places are fixed by ear clips. An ear clip connecting arm is connected to one side of the earphone body. The ear clip connecting arm can be clamped on the wearer's auricle to fix the wireless earphone. Existing ear clip connecting arms are generally made of rigid, elastic or plastic materials. Rigid and elastic ear clips have a fixed shape or a tendency to reset to a fixed shape. Their fixed shape is difficult to adapt to the ear shape of all users, and the wearing comfort and stability are poor. For plastic ear clips, since the wearer can only operate the ear clip with one hand to apply force to it in most cases, its deformation under force is difficult to control, which is inconvenient to use.

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

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

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

[0016] Preferably, the connector is provided with an elastic protective member that fits 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.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Figure 1 The figure is a schematic diagram of the overall structure of a wireless headset provided by an embodiment of the present invention.

[0025] like Figure 1 As shown, the present invention provides a wireless headset, including a first housing 1 and a connecting body 2. The first housing 1 is provided with an acoustic-electric module and a sound transmitting port (not shown in the figure), which is used to receive signals from an external terminal device and convert the audio signals into sound waves and transmit them from the sound transmitting port. The connecting body 2 is made of a 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 connecting body 2 has a deformation threshold, and can be deformed under a force higher than the deformation threshold, and can maintain its original shape under a force lower than the deformation threshold.

[0026] When the wearer wears the wireless headset, the first housing 1 is first installed outside the ear canal, and then force is applied to the connector 2 to cause the connector 2 to undergo plastic deformation, so that the first end 21 (first housing 1) and the second end 22 of the connector 2 are clamped on the wearer's auricle;

[0027] Moreover, the deformation threshold gradually increases from the middle of the connecting body 2 towards both ends. On the one hand, when the connecting body 2 is subjected to overall force, its main deformation part occurs in the middle, and the deformation amounts at both ends are relatively small. That is, the two end positions of the first end 21 and the second end 22 are in a relatively stable state, which is more convenient for the wearer to operate the first end 21 and the second end 22 to fix them on the auricle. Moreover, during the long-term wearing process after adjustment, the first end 21 and the second end 22 can maintain a stable cooperation state with the auricle, which can improve the wearing comfort and stability. On the other hand, the deformation threshold at the connection between the first end 21 and the first housing 1 is relatively high. Therefore, it can reduce the deformation amplitude of the connection part 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.

[0028] Among them, the first housing 1 is equipped with a sound-electricity module and a sound transmission port, which are very mature technologies in existing wireless earphones or wired earphones. In actual application, the specific shape of the first housing 1 and the specific opening position of the sound transmission port can be adaptively adjusted according to the specific specifications of the connecting body 2, which will not be elaborated here.

[0029] In addition, in order to further improve the connection stability between the first end 21 and the first housing 1, a rigid section can be set at the connection part between the first end 21 and the first housing 1 to prevent the connection part between the first end 21 and the first housing 1 from deforming.

[0030] Figure 2 is a schematic structural diagram of the connecting body of the wireless earphone provided by an embodiment of the present invention; Figure 3 is a schematic structural diagram of another perspective of the connecting body of the wireless earphone provided by an embodiment of the present invention.

[0031] As Figure 2 shown in Figure 3 the cross-sectional area of the connecting body 2 gradually increases from the middle towards the first end 21 and the second end 22, so as to realize that the deformation threshold gradually increases from the middle of the connecting body 2 towards both ends. It can be that the vertical width of the connecting body 2 at the position shown in Figure 3 gradually increases from the middle towards both ends, or the width of the connecting body 2 in the direction perpendicular to the paper surface in Figure 3 gradually increases from the middle towards both ends. In this way, the deformation threshold of the connecting body 2 can be realized to gradually increase from the middle towards both ends. In addition, the effect that the deformation threshold of the connecting body 2 gradually increases from the middle towards both ends can also be achieved by controlling the material density or material property difference between the middle and both ends of the connecting body 2, or by processing a material removal hole or a material removal groove in the middle of the connecting body 2 to make the material amount in the middle of the connecting body 2 less than that at both ends.

[0032] It should be noted that the cross-sectional area mentioned above is the effective area of ​​the connector 2 on the cross-section, rather than the area of ​​the contour enclosed by the outer edge of the connector 2 on the cross-section. For example, when the connector 2 is a hollow structure, only the solid area of ​​the annular shape formed by the connector 2 on the cross-section should be considered, and it should not be considered that the cross-sectional area also includes the area of ​​the hollow part.

[0033] like Figure 1 As shown, in one preferred embodiment, it also includes a second bin body 3 connected to the second end 22, and the second bin body 3 can be Figure 1 The shape shown in the figure is exactly the same as the first housing 1, and can also be other shapes suitable for clamping on the auricle. The second housing 3 can be used to install auxiliary components such as batteries and signal receivers, which can simplify the electrical structure in the first housing 1; a wire harness is provided in the connecting body 2, and the second housing 3 and the first housing 1 are electrically connected through the wire harness.

[0034] In one of the preferred embodiments, the outer surfaces of the first chamber body 1 and the second chamber body 3 are continuously transitioned arc surfaces 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 chamber body 1 and the second chamber body 3 that fit the wearer's ears can improve the wearing comfort.

[0035] Furthermore, a second fitting layer can be provided on the first chamber body 1 and the second chamber body 3. The second fitting layer is provided at the positions of the first chamber body 1 and the second chamber body 3 which are often in contact with the wearer's skin. After being clamped at the ear by the first chamber body 1, the connector 2 and the second chamber body 3, the wearer will not feel uncomfortable even if worn for a long time, thereby further improving the comfort.

[0036] like Figure 2 and Figure 3 As shown, in one of the preferred embodiments, a wiring groove 23 is opened on the surface of the connector 2 for arranging the wire harness. Through the arrangement of the wiring groove 23, when installing the wireless headset, the first compartment 1 and the second compartment 3 can be electrically connected and installed first, and then 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 requiring the wires to be threaded inside the ear clip connecting arm, the installation and preparation process of the wireless headset is simplified, and the production efficiency is improved.

[0037] Further, based on the above configuration, a detachable protective cover (not shown in the figure) may be provided on the wiring groove 23. When the protective cover is not installed, the wiring groove 23 is Figure 2The groove body shown is completely exposed to the outside world. In this way, the wire can also use an FPC flexible circuit board. The FPC flexible circuit board has high signal transmission efficiency, but its texture is relatively soft. By setting the groove body 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, and then a protective cover is installed on the wiring groove 23, which can provide good protection for the FPC flexible circuit board inside it, and then the FPC flexible circuit board can be connected to the first compartment 1 and the second compartment 3 of the headset.

[0038] It should also be noted that the protective cover should be made of a plastic material similar to the connector 2 to ensure that the function of plastic deformation of the connector 2 can be smoothly realized. The protective cover and the wiring groove 23 can be connected in a card slot card block connection, or a detachable connection can be achieved by screws, etc. A sealing gasket is also provided between the protective cover and the wiring groove 23 to enhance the protection effect 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 can have good bonding strength and good sealing at room temperature. When the protective cover needs to be removed, the pyrolytic adhesive is heated to make it lose its viscosity for easy removal.

[0039] In one preferred embodiment, a sealing structure is provided between the connector 2 and the first bin body 1 and the second bin body 3. On the one hand, it can protect the electrical components inside the first bin body 1 and the second bin body 3 to prevent external liquids or dust from entering the bin body, and on the other hand, it can also improve the connection strength between the connector 2 and the first bin body 1 and the second bin body 3. The sealing structure can be installed between the connector 2 and the bin body by injection molding sealant or injection molding plastic, which will not be described in detail here.

[0040] In one of the preferred embodiments, the material of the connector 2 is memory metal, which can specifically be nickel-titanium alloy or iron-based memory alloy, etc. The memory metal can undergo reversible deformation under a certain external force, has good restoring force and comfort, and is particularly suitable for applications in which the connector 2 in the present application needs to be repeatedly bent and adjusted in shape.

[0041] In addition, by utilizing the characteristics of the metal material of the connector 2, it can be expanded into a headset communication antenna, and its metal body can sense and receive signals from all directions. The memory metal shell of the connector 2 is connected to the main board in the headset through the FPC flexible circuit board, thereby transmitting the received signal to the main board of the headset and other corresponding processing modules, so that the main board can transmit signals with external terminals through the FPC flexible circuit board and the connector 2. This large antenna can greatly improve the wireless communication capability of the headset, while saving the structural space for setting up internal signal receiving components in the headset.

[0042] The connector 2 may also be made of other plastic materials according to actual cost control requirements, for example, aluminum alloys or organic polymer materials with excellent ductility may be used.

[0043] In one of the preferred embodiments, the surface of the connector 2 is coated with a first bonding layer, and the first bonding layer is made of a flexible material, such as silicone, rubber, etc. By coating the first bonding layer on the surface of the connector 2, 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 is set to gradually increase from the middle to the first end 21 and the second end 22, the first bonding layer can be coated and filled to make the connector 2 and the first bonding layer as a whole have a uniform shape, thereby improving the aesthetics of the wireless headset.

[0044] In one preferred embodiment, the connector 2 has an initial state, and the connector 2 is in a "C" shape in the initial state, that is, Figures 1 to 3 The shape of the single-sided opening shown in the figure is arranged so that the connector 2 forms the shape of an ear clip in the initial state, and the first end 21 and the second end 22 can be clamped on both sides of the wearer's auricle respectively. When the wearer actually wears and adjusts the connector 2, the deformation of the connector 2 that needs to be adjusted is small, thereby reducing the deformation of the connector 2 when the wireless headset is in use, and the operations that the wearer needs to perform when wearing the headset.

[0045] In one of the preferred embodiments, an elastic protective member is provided on the connector 2, and the elastic protective member can fit the outer contour of the connector 2. When the connector 2 is in the above-mentioned initial shape, the elastic force inside the elastic protective member is zero. Therefore, when the shape of the connector 2 is fine-tuned, the elastic resistance generated by the elastic protective member is small, so that the fine-tuning 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 deforming significantly, so that when the connector 2 is subjected to unexpected situations such as collision, extrusion or pulling, the resistance of the elastic protective member can provide better protection for the connector 2.

[0046] Among them, the elastic protective part can be a spring or other elastic element mounted on the connector 2, or the above-mentioned first bonding layer can be used as the elastic protective part. 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 part between the outer surface of the connector 2 and the wearer's auricle, and can also serve as an elastic protective part to protect the connector 2.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that any modification or equivalent replacement of the technical solutions of the present invention does not depart from the spirit and scope of the technical solutions of the present invention and should be included in the scope of the claims of the present invention.
