[0002] A Bluetooth headset is a headset that uses Bluetooth technology to wirelessly connect to an audio source device (such as a mobile phone, tablet computer, computer, etc.). Bluetooth headsets can eliminate the cables of traditional wired headsets and provide a more convenient user experience. Currently, Bluetooth headsets are roughly divided into two categories. One is an in-ear headset in which the sound element is in the user's ear canal when in use, and the other is an open-ear headset in which the sound element is worn outside the user's ear canal to produce sound. Since the sound element of the open-ear headset is suspended outside the user's ear canal, it is generally necessary to provide an ear hook on the headset body for assisting wearing; the ear hook generally includes a memory steel wire and a rubber bag wrapped around the outside of the memory steel wire.

[0019] Figure 3 It is a three-dimensional schematic diagram of the memory steel wire provided by the embodiment of the utility model. DETAILED DESCRIPTION

[0020] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0021] like Figures 1 to 3 As shown, the utility model provides a specific embodiment of an earphone ear hook.

[0022] A headphone ear hook, reference Figures 1 to 3 The earphone ear hook includes: a connecting component 1, a wire 2, a memory steel wire 3 and a protective cover 4. The connecting component 1 is arranged at one end of the memory steel wire 3 for connecting the earplug, and the protective cover 4 is sleeved on the outside of the memory steel wire 3 and the wire 2; wherein the memory steel wire 3 includes an arc segment 31 and a first straight segment 32, and the memory steel wire 3 is connected to the connecting component 1 through the first straight segment 32.

[0023] Specifically, refer to Figures 1 to 3 The headphone ear hook is used on the Bluetooth headset to fix the earplug on the ear, thereby providing a stable wearing method; the memory wire 3 is usually an alloy with shape memory function, which is used to help the ear hook maintain a specific shape or curvature to ensure that the ear hook can better fit the ear and provide a more stable and comfortable wearing experience; the connecting component 1 is used to connect the earplug, and the headphone ear hook is connected to the earplug through the connecting component 1; the wire 2 is used to power the earplug, one end of the wire 2 is connected to the power supply, and the other end of the wire 2 is connected to the circuit module in the earplug to provide power to the circuit module in the earplug.

[0024] Further, refer to Figures 1 to 3 The protective cover 4 is arranged on the outside of the wire 2 and the memory wire 3. On the one hand, the protective cover 4 can provide a certain friction force, which can increase the friction between the ear hook and the ear, prevent the ear hook from sliding or falling during activities, and provide a more stable wearing; and the protective cover 4 is relatively soft, which can reduce the damage of the ear hook to the ear, and can also reduce the discomfort that may be caused when the ear hook directly contacts the ear, thereby providing a better fit and stability; on the other hand, the protective cover 4 has a certain waterproof performance, which can help prevent sweat or water vapor from entering the inside of the ear hook, thereby extending the service life of the ear hook; the protective cover 4 can also reduce the damage caused by the friction between the ear hook and the external environment, thereby extending the service life of the ear hook.

[0025] Further, refer to Figures 1 to 3 The memory steel wire 3 is not only provided with an arc segment 31 designed to fit the ear, but also has a first straight segment 32. One end of the memory steel wire 3 used to connect the connecting component 1 is set as a straight line. When injection molding is performed to fix the memory steel wire 3 and the connecting component 1, the first straight segment 32 of the memory steel wire 3 can be placed in the mold to be consistent with the mold requirements. Moreover, since the part of the memory steel wire 3 placed in the mold is a straight line, the position after being placed in the mold is more precise, and it is not easy to deform during the injection molding process, which effectively reduces the defective rate of the product, thereby improving product quality and production efficiency.

[0026] In the prior art, 40% to 50% of the ear hook rubber coating leaks, that is, the memory steel wire is not covered or the memory steel wire is almost exposed with a thickness of less than 0.3, resulting in a defective product. This defect is mainly caused by the deformation of the semi-finished product after hard glue injection molding; and the reason for injection molding deformation is generally that the size accuracy of the memory steel wire does not match the mold requirements. The mold injection molding sealing requirement is about 0.03mm on one side to avoid leakage, while the manufacturing accuracy of the memory steel wire is plus or minus 0.08mm, which is a certain distance from the injection molding accuracy requirement of the mold. In addition, the memory steel wire is not clearly positioned on the left and right when it is placed in the mold, which makes the memory steel wire easily compressed in the mold and deformed after demolding, which makes the silicone coating easy to leak.

[0027] In this embodiment, by designing an earphone ear hook, by setting the end of the memory steel wire of the earphone ear hook as a straight segment, when the memory steel wire is placed in the mold for injection molding to be fixed with other components, the placement position between the end of the memory steel wire and the mold is more precise, and it is not easy to deform during the injection molding process, so that the subsequent rubber wrapping of the protective cover is more comprehensive, and the phenomenon of rubber wrapping leaking out is effectively avoided.

[0028] In one embodiment, reference Figure 2 The connecting component 1 includes a rotating shaft 11 for connecting the earplug and a first injection molded part 12 for connecting the rotating shaft 11 and the first straight line segment 32 .

[0029] Specifically, refer to Figure 2 The hinge 11 is a component used to connect the ear hook and the earplug, which allows the ear hook to rotate or tilt in the horizontal and vertical directions so that the ear hook can better fit the ear, thereby adapting to different ear shapes and sizes. The position of the ear hook can be better adjusted by rotating or tilting the ear hook to provide a more comfortable wearing experience; and the hinge 11 can also keep the ear hook stable when the head moves, so that the ear hook rotates naturally with the movement of the head, avoiding the ear hook from falling off or becoming uncomfortable due to head movement; and the design of the hinge 11 can also make the ear hook more adjustable, and the user can adjust the angle and position of the ear hook according to his or her preferences and needs to obtain a different audio experience. The appropriate design of the hinge 11 can also reduce the wear of the ear hook during frequent rotation or tilting, thereby extending the service life of the ear hook.

[0030] The first injection molded part 12 is used to fix the rotating shaft 11 and the memory steel wire 3 to improve the stability of the product.

[0031] In one embodiment, reference Figures 1 to 3 The earphone ear hook also includes a mounting assembly 5 , and the memory steel wire 3 also includes a second straight line segment 33 , and the memory steel wire 3 is connected to the mounting assembly 5 via the second straight line segment 33 .

[0032] Specifically, refer to Figure 1 and Figure 2 The mounting assembly 5 includes a battery mounting part 51 for mounting a battery and a second injection molded part 52 for connecting the battery mounting part 51 and the second straight segment 33. By setting the part of the other end of the memory steel wire 3 used for connecting the battery mounting part 51 as a straight segment, when performing injection molding to fix the memory steel wire 3 and the battery mounting part 51, the first straight segment 32 of the memory steel wire 3 can be placed in the mold to be consistent with the mold requirements. Moreover, since the part of the memory steel wire 3 placed in the mold is a straight line, the position after being placed in the mold is more precise, and it is not easy to deform during the injection molding process, which effectively reduces the defective rate of the product, thereby improving product quality and production efficiency.

[0033] In one embodiment, the earphone ear hook further includes a battery, which is disposed in a battery mounting member 51 and electrically connected to the wire 2 .

[0034] Specifically, the battery is used to provide electrical energy. Since TWS headphones generally have a driving unit, a noise reduction unit, etc., each functional unit requires a stable power supply to operate normally. The battery is used to provide the required power to each functional unit so that the headphones can be used normally.

[0035] In one embodiment, reference Figure 1 and Figure 2 The earphone ear hook also includes an interface 6, one end of the wire 2 passes through the connecting component 1 and is connected to the interface 6; the interface 6 is used to be electrically connected to the earplug, and the battery is electrically connected to the earplug through the wire 2, so as to power the various functional modules in the earplug.

[0036] In one embodiment, reference Figure 1 and Figure 2 A avoidance groove 111 is provided on the rotating shaft 11 , and one end of the wire 2 extends to the outside of the rotating shaft 11 through the avoidance groove 111 and is connected to the interface 6 .

[0037] In one embodiment, the protective cover 4 is a silicone cover; and the silicone cover is a liquid silicone cover.

[0038] The utility model also provides a specific embodiment of a TWS headset.

[0039] A TWS headset, the TWS headset includes the earphone ear hook as described above, and also includes an earplug, and the earplug is connected to a connecting component.
