Abstract
Description
Technical Field
[0001] This utility model relates to the field of audio equipment technology, specifically to a composite plug wired headphone. Background Technology
[0002] In the field of audio equipment, with the diversification of smart terminals, users have put forward higher requirements for the compatibility and functionality of headphones. Traditional wired headphones are usually only equipped with a single type of plug (such as a 3.5mm analog plug or a Type-C digital plug).
[0003] In existing technologies, multiple data cables lack a systematic storage and fixing design. Data cables are prone to tangling and knotting due to disordered stacking. This not only significantly reduces the convenience of user operation, but may also cause the internal conductors of the data cable to break or the insulation layer to be damaged due to excessive bending, which in turn leads to faults such as poor contact and abnormal signal transmission, and greatly shortens the actual service life of the product. Utility Model Content
[0004] The purpose of this invention is to provide a composite plug wired earphone to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a composite plug wired earphone, including a controller, with data cables electrically connected to the left and right sides of the controller, a storage mechanism on the controller, and a fixing mechanism on the storage mechanism;
[0006] The storage mechanism includes a partition plate, which is fixedly connected to the top and bottom of the controller. The top and bottom of the controller are respectively hinged to a top cover. The inner sides of the two top covers are provided with elongated slots. A cover plate is hinged to one side of the top of the partition plate. Magnetic plates are fixedly connected to the top and bottom of the controller. Magnetic blocks are fixedly connected to both ends of the top cover near the controller. The magnetic blocks are placed on the magnetic plates. When the top cover is placed on the controller, the magnetic blocks and magnetic plates make magnetic contact, allowing the top cover to be fixedly placed on the controller, thus protecting the data cable during storage.
[0007] Preferably, there are two long slots, and the front, back, and inner sides of the upper and lower long slots are set as openings.
[0008] Preferably, there are two partition plates, with the upper and lower partition plates arranged symmetrically, and the slots on the corresponding data line side of the upper and lower partition plates are in opposite directions.
[0009] Preferably, the fixing mechanism includes a rectangular groove, which is formed inside the partition plate on the side away from the controller. A second trapezoidal plate is fixedly connected to the cover plate on the side near the controller. A spring is fixedly connected to the left side of the partition plate. A telescopic rod is fixedly connected to the left side of the partition plate. A movable plate is fixedly connected to the right side of the telescopic rod and the spring. A first trapezoidal plate is fixedly connected to the right side of the movable plate.
[0010] Preferably, the rectangular groove has openings on the front, rear, and top sides, and the cover plate is disposed inside the rectangular groove.
[0011] Preferably, there are two telescopic rods and two springs, with the springs disposed on the surface of the telescopic rods.
[0012] Preferably, the first trapezoidal plate is disposed behind the second trapezoidal plate. The first and second trapezoidal plates are mirror symmetrical. The inclined surfaces of the first and second trapezoidal plates are inclined towards each other and completely fit together. When the inclined surfaces of the two trapezoidal plates are in contact and constrained, a normal pressure perpendicular to the inclined surface and a frictional force along the inclined surface will be generated, forming a mechanical lock. This can fix the position of the cover plate and prevent the cover plate from moving arbitrarily.
[0013] Compared with the prior art, the present invention provides a wired headphone with a composite plug that has the following advantages:
[0014] 1. This composite plug wired earphone, through a storage mechanism, places the data cable in a slot composed of multiple partition plates. By moving the cover plate at the top of the partition plates, the data cable is positioned between the controller and the cover plate, preventing the data cable from becoming loose. The first trapezoidal plate is located on the back of the second trapezoidal plate. When the inclined surfaces of the two trapezoidal blocks are in contact and constrained, a normal pressure perpendicular to the inclined surface and a frictional force along the inclined surface are generated, forming a mechanical lock that can fix the position of the cover plate and prevent the cover plate from moving arbitrarily.
[0015] 2. This composite plug wired earphone, through a fixing mechanism, allows the top cover to be moved so that when the top cover is placed on the controller, the magnet block and magnet plate make magnetic contact, which can fix the top cover on the controller and protect the data cable when storing it.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0026] This utility model provides the following technical solution:
[0027] Example 1
[0028] Combination Figures 1 to 3 A composite plug wired earphone includes a controller 2, with data cables 1 electrically connected to the left and right sides of the controller 2 respectively, a storage mechanism 3 on the controller 2, and a fixing mechanism 4 on the storage mechanism 3.
[0029] The storage mechanism 3 includes a partition plate 31, which is fixedly connected to the top and bottom of the controller 2. The top and bottom of the controller 2 are respectively hinged to a top cover 32. The inner sides of the two top covers 32 are provided with long slots 33. A cover plate 36 is hinged to one side of the top of the partition plate 31. The top and bottom of the controller 2 are respectively fixedly connected to a magnetic plate 35. The two ends of the top cover 32 near the controller 2 are respectively fixedly connected to magnetic blocks 34. The magnetic blocks 34 are set on the magnetic plate 35.
[0030] There are two long slots 33, with openings on the front, back, and inner sides of the upper and lower long slots 33. There are two partition plates 31, with the upper and lower partition plates 31 arranged symmetrically. The slots on the side of the upper and lower partition plates 31 corresponding to the data line 1 are in opposite directions.
[0031] Furthermore, the data cable 1 is placed in a slot composed of multiple partition plates 31. The cover plate 36 is moved on top of the partition plate 31, so that the data cable 1 is positioned between the controller 2 and the cover plate 36, preventing the data cable 1 from becoming loose. The first trapezoidal plate 45 is positioned on the back of the second trapezoidal plate 46. When the inclined surfaces of the two trapezoidal blocks are in contact and constrained, a normal pressure perpendicular to the inclined surface and a frictional force along the inclined surface will be generated, forming a mechanical lock, which can fix the position of the cover plate 36 and prevent the cover plate 36 from moving at will.
[0032] Example 2
[0033] See Figure 1-5 Furthermore, based on Embodiment 1, the fixing mechanism 4 includes a rectangular groove 41, which is opened inside the partition plate 31 on the side away from the controller 2. A second trapezoidal plate 46 is fixedly connected to the cover plate 36 on the side close to the controller 2. A spring 42 is fixedly connected to the left side of the partition plate 31. A telescopic rod 43 is fixedly connected to the left side of the partition plate 31. A movable plate 44 is fixedly connected to the right side of the telescopic rod 43 and the spring 42. A first trapezoidal plate 45 is fixedly connected to the right side of the movable plate 44.
[0034] The rectangular groove 41 has openings on the front, back, and top sides. The cover plate 36 is located inside the rectangular groove 41. There are two telescopic rods 43 and two springs 42. The springs 42 are located on the surface of the telescopic rods 43. The first trapezoidal plate 45 is located behind the second trapezoidal plate 46. The first trapezoidal plate 45 and the second trapezoidal plate 46 are mirror symmetrical. The inclined surfaces of the first trapezoidal plate 45 and the second trapezoidal plate 46 are inclined towards each other and fit together completely.
[0035] Furthermore, when the top cover 32 is placed on the controller 2, the magnet block 34 and the magnet plate 35 come into magnetic contact, which allows the top cover 32 to be fixedly placed on the controller 2, thus protecting the data cable 1 when it is stored.
[0036] In actual operation, when this device is used, it integrates a 3.5mm three-prong plug ( Figure 6 J1) and Type-C digital plug ( Figure 6 The composite plug module (J2) in the controller 2 contains a total of speaker units ( Figure 6 (SPL / SPR) and microphone ( Figure 6 MIC1); 4.7KΩ current limiting resistor (R1) is set at the 3.5mm plug end; dual-channel signal isolation capacitors (C1 / C2 / C3 / C4 are 10μF capacitors);
[0037] Connect a 4.7KΩ surface mount resistor in series at the MIC input terminal of the 3.5mm plug (to reduce the microphone operating current from 15mA to 3mA);
[0038] Each of the left and right audio channel output terminals of the 3.5mm plug and Type-C interface has a 10μF DC blocking capacitor connected in series (to block digital signal crosstalk);
[0039] It can achieve automatic switching between 3.5mm and Type-C dual modes; the echo cancellation effect is improved; the microphone circuit power consumption is reduced, solving the problems of high call current and echo caused by the simultaneous presence of two plugs. (According to the attached...) Figure 6 The circuit flow described in the text can be implemented;
[0040] The headphones have a 3.5mm analog plug and a Type-C digital plug connected in parallel; a 4.7KΩ current-limiting resistor is connected in series with the MIC line of the 3.5mm plug; and a 10μF signal isolation capacitor is set for each of the left and right channels.
[0041] When the headphones are not in use, they need to be stored. At this time, the left and right data cables 1 can be placed in the slots formed by multiple partitions 31. The right data cable 1 can be placed through the right slot corresponding to the top partition 31, and the left data cable 1 can be placed through the right slot corresponding to the bottom partition 31.
[0042] When the cover plate 36 is moved at the top of the partition plate 31, the data cable 1 is positioned between the controller 2 and the cover plate 36 to prevent the data cable 1 from becoming loose. Under the rebound force of the spring 42, the telescopic rod 43 is stretched until both the spring 42 and the telescopic rod 43 drive the moving plate 44 to move. The moving plate 44 drives the first trapezoidal plate 45 to be positioned on the back of the second trapezoidal plate 46. When the inclined surfaces of the two trapezoidal blocks are in contact and constrained, a normal pressure perpendicular to the inclined surface and a frictional force along the inclined surface will be generated, forming a mechanical lock. This can fix the position of the cover plate 36 and prevent the cover plate 36 from moving arbitrarily.
[0043] When the top cover 32 is moved again and placed on the controller 2, the magnet 34 and the magnet plate 35 come into magnetic contact, which can fix the top cover 32 on the controller 2 and protect the data cable 1 when it is stored.
[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
