Description

Technical Field

[0001] This utility model relates to the field of electronic device accessory design technology, and in particular to a bending adjustment component and headphones. Background Technology

[0002] Headphones receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers (the headphone body) placed close to the ears. Currently, headphones on the market are generally divided into wired and wireless designs, with wired headphones typically connecting to a media player via a plug.

[0003] Existing wired headphones feature a right-angle connection between the plug and the headphone cable (i.e., the plug axis forms a 90° angle with the headphone cable). Since the headphone cable at the plug location cannot be adjusted for bending angle, this can easily lead to interference with other electronic devices. For example, when both the charging cable and headphone cable plugs are used on a multimedia device, the headphone cable at the plug location can interfere with the charging cable. This forces users to choose between using either the headphones or the charger, causing significant inconvenience.

[0004] Therefore, finding a technical solution that can solve the above-mentioned technical problems has become an important research topic for those skilled in the art. Utility Model Content

Detailed Implementation

[0040] This utility model discloses a bending adjustment component and an earphone, which solves the technical problem that the earphone wire at the plug position of existing earphones cannot be bent and adjusted, thus causing the earphone wire at the plug position to easily interfere with other electronic devices.

[0041] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please see Figures 1 to 4 This utility model provides a bending adjustment component for adjusting the bending angle of an earphone cable 3, wherein the two ends of the earphone cable 3 are respectively connected to an earphone body and a plug 4;

[0043] The bending adjustment assembly includes a connector 1, a fixing structure, and multiple bending units 2;

[0044] The connector 1 is fitted onto the headphone cable 3 and connected to the root 401 of the plug 4. Multiple bending units 2 are arranged sequentially along the extension direction of the headphone cable 3 at a preset distance, and the multiple bending units 2 form a channel for the headphone cable 3 to pass through. The bending unit 2 near the plug 4 is connected to the connector 1. Two adjacent bending units 2 are rotatably connected and fixed to each other by the fixing structure after rotating relative to each other by a preset angle.

[0045] It should be noted that this embodiment does not limit the preset angle mentioned above. Operators can choose a suitable angle according to actual needs, such as 30°, 35°, 40°, etc.

[0046] In this embodiment of the bending adjustment assembly, the connector 1 is connected to the root 401 of the plug 4. Multiple bending units 2 are arranged sequentially along the extension direction of the headphone cable 3 at a predetermined distance, forming a channel for the headphone cable 3 to pass through. The bending unit 2 closest to the plug 4 is connected to the connector 1. Adjacent bending units 2 are rotatably connected and fixed together by a fixing structure after rotating relative to each other by a predetermined angle. In this design, the user can rotate the bending unit 2 to bend the headphone cable 3 at the plug 4 at a predetermined angle. After the headphone cable 3 is bent, the fixing structure secures the adjacent bending units 2, thus fixing the adjustment angle. Through this design, the user can bend and adjust the headphone cable 3 according to actual usage, thereby adjusting the direction of the headphone cable 3 at the plug 4, thus preventing interference between the headphone cable 3 at the plug 4 and other electronic devices during use, making it more convenient for the user.

[0047] It should also be noted that in this embodiment, it is preferred that two adjacent bending units 2 are detachably rotatably connected. With the above design, users can choose different numbers of bending units 2 to use in combination to adapt to different lengths of headphone wires 3 according to actual conditions.

[0048] In addition, in this embodiment, a preset distance is left between two adjacent bending units 2 so that the bending unit 2 can achieve rotational movement.

[0049] Furthermore, the bending unit 2 in this embodiment specifically includes an annular portion 201, a rotating shaft 202, and a first rotating hole 205 that cooperates with the rotating shaft 202;

[0050] The annular portion 201 is provided with a through hole 206, and the through holes 206 of the plurality of bending units 2 are arranged in sequence to form the channel;

[0051] The rotating shaft 202 and the first rotating hole 205 are respectively disposed on opposite sides of the annular portion 201. The rotating shaft 202 of the bending unit 2 is rotatably connected to the first rotating hole 205 of an adjacent bending unit 2 so that two adjacent bending units 2 are rotatably connected.

[0052] It should be noted that the annular portion 201 in this embodiment is specifically a circular or elliptical annular structure, and designers can choose according to the actual situation. Furthermore, in this embodiment, it is preferable that the diameter of the aforementioned through hole 206 matches the diameter of the headphone cable 3 to facilitate bending adjustment.

[0053] Additionally, it should be noted that the number of pivots 202 in the bending assembly can be one or two. When there are two pivots 202, the two pivots 202 are arranged vertically on one side of the annular portion 201. Furthermore, the number of first rotating holes 205 must be the same as the number of pivots 202.

[0054] Furthermore, the fixing structure in this embodiment includes a first engaging portion 203 and a first engaging groove 204;

[0055] The first engaging portion 203 and the first engaging groove 204 are respectively disposed on opposite sides of the annular portion 201;

[0056] After two adjacent bending units 2 rotate relative to each other by a preset angle, the first engaging part 203 and the first engaging groove 204 engage with each other to fix the two adjacent bending units 2 to each other.

[0057] It should be noted that, through the above design, the two bending units 2 can be fixed after rotating relative to each other, thereby achieving the fixation of the adjustment angle.

[0058] In addition, the first engaging part 203 and the first engaging groove 204 mentioned above are only one specific embodiment of the fixing structure. In another specific embodiment, the fixing structure mentioned above can be a magnetic suction part, which is disposed in the annular part 201.

[0059] After two adjacent bending units 2 rotate relative to each other by a preset angle, the magnetic attraction parts of the two adjacent bending units 2 attract each other to fix the two adjacent bending units 2 to each other.

[0060] It should be noted that the angle can also be fixed by using the two magnetic attraction parts to attract each other.

[0061] In addition, it can be simply understood that the magnetic attraction part mentioned above is a magnet. The magnetic pole of the magnet on one of the bending units 2 needs to be opposite to the magnetic pole on the adjacent bending unit 2 in order for the two to be effectively attracted and fixed.

[0062] Furthermore, in this embodiment, the connector 1 can be fixedly connected to the root 401 of the plug 4 using various connection methods.

[0063] In one specific embodiment, the connector 1 can be fixed to the root 401 of the plug 4 by snap-fit. Specifically, the connector 1 includes a connecting part 102 and a pair of clamping plates 101 connected to the connecting part 102 and used to clamp the root 401 of the plug 4.

[0064] A through hole 106 is provided between the pair of clamping plates 101 for the earphone cable 3 to pass through the channel, and a locking protrusion 103 is provided on the inner side wall of the clamping plate 101 to abut against the root 401 of the plug 4.

[0065] It should be noted that in the above design, the bending component can be used as an accessory. When the user needs to use it, it can be assembled with the headphone cable 3 and the plug 4. During assembly, the base 401 of the plug 4 is inserted into the through hole 106, and then the two clamping plates 101 clamp and fix the base 401 of the plug 4 by engaging the protrusions 103.

[0066] In the above specific embodiments, in order to prevent the pair of clamping plates 101 from becoming loose from the root 401 of the plug 4 during the clamping process, the connector 1 also includes a snap-fit ​​structure, which includes a second snap-fit ​​part 104 and a second snap-fit ​​groove 105.

[0067] The second engaging portion 104 is connected to the outer side wall of one of the clamping plates 101, and the second engaging groove 105 is disposed on the outer side wall of the other clamping plate 101 and is disposed opposite to the second engaging portion 104.

[0068] The second engaging portion 104 engages with the second engaging groove 105 to continuously clamp the root 401 of the plug 4 with the pair of clamping plates 101.

[0069] It should be noted that, through the above design, when the root 401 of the plug 4 is clamped by a pair of clamping plates 101, the pair of clamping plates 101 can be locked by the mutual engagement of the second engaging part 104 and the second engaging groove 105, thereby preventing the pair of clamping plates 101 from becoming loose from the root 401 of the plug 4 during the clamping process.

[0070] In addition, in this specific embodiment, a second rotating hole is provided on the side of the connecting part 102 near the bending unit 2;

[0071] The pivot 202 of one of the bending units 2 near the plug 4 is rotatably connected to the second pivot hole.

[0072] It should be noted that in order to fix the adjustment angle after the bending unit 2 rotates relative to the connector 1, the connector 1 should also be designed with a first engaging groove 204 that cooperates with the first engaging part 203.

[0073] In another specific embodiment, the connector 1 in this embodiment is integrally injection molded with the root 401 of the plug 4.

[0074] It should be noted that, by adopting the above method, the bending adjustment component and the root 401 of the plug 4 are integrally formed.

[0075] In this specific embodiment, the connector 1 is provided with a second rotating hole that cooperates with the rotating shaft 202;

[0076] The pivot 202 of one of the bending units 2 near the plug 4 is rotatably connected to the second pivot hole.

[0077] It should be noted that in order to fix the adjustment angle after the bending unit 2 rotates relative to the connector 1, the connector 1 should also be designed with a first engaging groove 204 that cooperates with the first engaging part 203.

[0078] Furthermore, in this embodiment, the bending adjustment component specifically allows the headphone cable 3 at the plug 4 to bend at an angle ranging from 30° to 90°.

[0079] Please see Figures 1 to 4 The present invention provides an earphone, including an earphone cable 3, an earphone body, a plug 4, and the aforementioned bending adjustment component;

[0080] The plug 4 and the earphone body are respectively connected to the opposite ends of the earphone cable 3;

[0081] The end of the plug 4 near the headphone wire 3 is the root 401;

[0082] The bending adjustment assembly includes a connector 1, a fixing structure, and multiple bending units 2;

[0083] The connector 1 is fitted onto the headphone cable 3 and connected to the root 401 of the plug 4. Multiple bending units 2 are arranged sequentially along the extension direction of the headphone cable 3 at a preset distance, and the multiple bending units 2 form a channel for the headphone cable 3 to pass through.

Adjacent bending units 2 are rotatably connected and fixed together by a fixing structure after rotating relative to each other by a predetermined angle. In this design, the user can rotate the bending unit 2 to bend the earphone cable 3 at the plug 4 at a predetermined angle. After the earphone cable 3 is bent and adjusted, the fixing structure fixes adjacent bending units 2, thereby fixing the adjustable angle.
