[0006] In one embodiment, both clamping surfaces are non-slip surfaces.

[0007] In one embodiment, the anti-slip surface is a serrated surface.

[0008] In one embodiment, the clamping member includes a first clamping member, a second clamping member, and an elastic member. The first clamping member is fixed to the adapter, and the second clamping member is rotatably mounted on the first clamping member.

[0010] In one embodiment, the limiting member forms a limiting groove, one end of the second clamping member having a clamping surface is located in the limiting groove, and the one end of the second clamping member having a clamping surface opens and closes relative to the first clamping member in the limiting groove.

[0011] In one embodiment, the first adapter and the second adapter are in line contact.

[0012] In one embodiment, one of the first adapter and the second adapter is provided with a socket, and the other is provided with a pin. The end of the pin is spherical or arc-shaped.

At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0037] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0038] Please refer to Figure 1 In one embodiment, a testing device is provided. This testing device is used to test the electrical signal transmission performance inside the earphone, mainly to test the internal cable transmission performance of the wireless Bluetooth earphone, so as to ensure the accuracy and stability of electrical signal transmission between the internal circuit board of the earphone and functional components such as microphones and speakers, so as to ensure the performance of the wireless Bluetooth earphone.

[0039] The testing equipment mainly includes a test host 100 and a test adapter 200. The test host 100 is the main component of the test and includes necessary modules such as a processing module, a control module, and a display module. The test adapter 200 is mainly used to fix the test headset and as a transitional electrical connection device to establish an electrical connection between the test host 100 and the test headset, so that the test host 100 can send test signals to the test headset and receive signals from the test headset, in order to ultimately measure whether the cable performance of the test headset is qualified.

[0040] The test adapter 200 includes the test adapter in any of the following embodiments. After the test earphone is installed, the test adapter 200 forms good fixed stability and electrical connection stability with the cable of the test earphone. During long-term testing, it can ensure the stability of the electrical connection between the test adapter 200 and the cable of the earphone under test, thereby ensuring that the test host 100 can accurately measure whether the cable performance of the test earphone is qualified.

[0041] This testing equipment is mainly used to test the transmission performance of headphone cables. When the test adapter 200 is equipped with other detachable fixed modules, this testing equipment can also test the transmission performance of cables of other electronic products, such as wired headphones or data cables.

[0042] Please refer to Figure 2 In one embodiment, the testing equipment further includes a test chamber 300, which has an openable and closable door. A closed testing space can be formed inside the test chamber 300. The test adapter 200 can be detachably installed entirely or partially inside the test chamber 300. The detachable parts of the test adapter 200 and the test chamber 300 can be removed and inserted through the door of the test chamber 300. Part or all of the test host 100 can be installed in the test chamber 300, or the test host 100 can be separately installed from the test chamber 300, with the test host 100 located outside the test chamber 300. The test chamber 300 has corresponding cable avoidance positions so that the test host 100 can be electrically connected to the test adapter 200 via cables.

[0043] The test chamber 300 is designed so that during the test, the test adapter 200 and the fixed test headphones are located inside the test chamber 300. The test chamber 300 provides closed protection for the test headphones, avoiding external electromagnetic interference and other influences during the test, thus ensuring the accuracy of the test.

[0044] Please refer to Figure 3 In one embodiment, the test adapter 200 is part of the test equipment in the above embodiments. The test adapter 200 is mainly used to install and fix the test headphones and their cables to serve as a converter circuit and realize the electrical connection between the test host 100 and the test headphones' cables.

[0045] The test adapter 200 mainly includes a mounting base 1, an adapter base 2, and a support base 3. The mounting base 1 is mainly used to fix the test earphone, the adapter base 2 is mainly used to clamp the cable of the test earphone and to play the role of circuit conversion, and the support base 3 is the supporting component of the entire test adapter 200, mainly playing the role of support and fixation.

[0046] Mounting base 1, adapter base 2, and support base 3 can be arranged sequentially from top to bottom, with mounting base 1 mounted on top of adapter base 2, and adapter base 2 mounted on top of support base 3. This arrangement places the test earphone at the top, facilitating the installation and removal of the test earphone, as well as the mounting base 1 and adapter base 2. In other embodiments, mounting base 1 and adapter base 2 can also be mounted side-by-side or front-back on support base 3, with adapter base 2 also serving as a circuit adapter.

[0047] Please refer to Figure 4 In this embodiment, the mounting base 1 is provided with an earphone fixing position 11, which can be a groove structure adapted to the shape of the test earphone. For example, if the test earphone has a C-shaped structure, the earphone fixing position 11 is set as a corresponding C-shaped groove structure, so that the earphone under test is placed inside the groove of the earphone fixing position 11. The shape of the groove structure itself can directly limit the test earphone, without the need to set other auxiliary structures for positioning and fixing. This setting simplifies the structure of the mounting base 1, and the test earphone can also be disassembled and assembled in one step, improving the disassembly and assembly efficiency of the test earphone.

[0048] In other embodiments, the headphone fixing position 11 can also have other structures. For example, the headphone fixing position 11 may have a placement space such as a placement slot, and a movable limiting structure is provided in the placement space. The placement space has a large initial space so that multiple headphones of different sizes and structures can be placed in it. After the headphone to be tested is placed in the placement space of the headphone fixing position 11, the movable limiting structure fixes the test headphone in the placement space of the headphone fixing position 11, which can also realize the disassembly and fixing of the test headphone, as well as the fixing of different headphones. The movable limiting structure includes a clamping part connected with a spring, etc.

[0049] Please refer to Figure 4 In this embodiment, the mounting base 1 is further provided with a lead wire portion 12. An opening is provided on the side of the groove structure of the earphone fixing position 11, and the lead wire portion 12 is provided at this opening. The lead wire portion 12 has a slot or similar structure and is used to fix the test earphone cable by snapping it in place. The lead wire portion 12 is also used to change the arrangement direction of the test earphone cable so that the test earphone cable can extend to the corresponding clamping position of the adapter 2, thereby ensuring the stability and accuracy of the electrical connection of the test earphone cable.

[0050] The mounting base 1 can be an integrated structure. The headphone fixing position 11 and the lead wire part 12 of the mounting base 1 can be integrally formed by injection molding or other methods. The integrated structure of the mounting base 1 has higher structural stability and can eliminate the installation connection structure such as screws, which is conducive to the miniaturization and simplification of the mounting base 1.

[0051] In other embodiments, when the opening on the side of the groove structure of the earphone fixing position 11 is close to and aligned with the clamping position corresponding to the adapter 2, the mounting base 1 may not be provided with the lead wire part 12. The cable of the test earphone installed in the earphone fixing position 11 can be led out from the side opening of the earphone fixing position 11 and directly connected to the clamping structure corresponding to the adapter 2.

[0052] Please refer to Figure 5 and Figure 6 In this embodiment, the adapter 2 is provided with a clamping member 21 and a first adapter member 22. The clamping member 21 is installed at the upper end of the adapter 2. For example, the clamping member 21 is located at the upper side of the adapter 2. This arrangement makes the clamping member 21 closer to the mounting base 1 at the upper end, and allows the clamping member 21 to be closer to the test earphone. Within the length extension range of the test earphone cable, the clamping member 21 can clamp the test earphone cable.

[0053] Please refer to Figure 10 The support base 3 is provided with a second adapter 31, and the first adapter 22 can be installed at the lower end of the adapter base 2. For example, the first adapter 22 can be installed on the bottom plate of the adapter base 2 so that the first adapter 22 is closer to the second adapter 31 of the lower support base 3, allowing the first adapter 22 and the second adapter 31 to form an electrical connection through direct contact. The clamping member 21 and the first adapter 22 can be electrically connected through a first electrical connection line (not shown in the figure) such as a cable or a flexible flat cable. The first electrical connection line has the characteristics of flexible bending and routing, which allows the clamping member 21 and the first adapter 22 to be set in different positions and orientations, improving the freedom of installation of the clamping member 21 and the first adapter 22. For example, the clamping member 21 can be set at the upper side of the adapter base 2. In some embodiments, the first adapter 22 can be set at the lower middle part of the adapter base 2.

[0054] The adapter 2 may have a through hole on its side plate, and the clamping member 21 has a connecting part. The connecting part of the clamping member 21 passes through the through hole of the adapter 2 and is electrically connected to the first electrical connection line. In some embodiments, the first electrical connection line may also pass through the through hole of the adapter 2 and be electrically connected to the connecting part of the clamping member 21. The clamping member 21 is a clamp structure made of conductive metal, or the clamping part of the clamping structure of the clamping member 21 is made of conductive metal. The clamping member 21 is used to clamp the cable of the test earphone. The clamped part of the test earphone cable is the stripped metal wire part. After the clamping member 21 clamps the test earphone cable, it fixes the test earphone cable, and the clamping member 21 and the test earphone cable form an electrical connection. The clamping member 21 simultaneously achieves physical clamping and contact electrical connection.

[0055] The first adapter 22 and the second adapter 31 can be plug-in terminals made of conductive metal. After the first adapter 22 and the second adapter 31 are mated or plugged into each other, a contact-type electrical connection can be formed. The second adapter 31 can be electrically connected to the test host 100 through a second electrical connection wire (not shown in the figure).

[0056] In this embodiment, after the test earphone is installed, the cable of the test earphone is electrically connected to the test host 100 in sequence through the clamp 21, the first electrical connection line, the first adapter 22, the second adapter 31, and the second electrical connection line. The test host 100 and the cable of the test earphone form a test circuit, enabling the test host 100 to perform performance testing on the cable of the test earphone.

[0057] The clamping member 21 may include multiple independent clamping structures or multiple linked clamping structures, so that the clamping member 21 can simultaneously clamp multiple cables of the test headphone to test multiple headphone cables at the same time. For example, the clamping member 21 includes two independent clamping structures, which can be identical or structurally different. The two independent clamping structures can open and close synchronously or asynchronously to clamp two cables. Correspondingly, multiple first adapters 22 and second adapters 31 are provided, so that one clamping structure of the clamping member 21 can correspond to one first adapter 22 and one second adapter 31 to form multiple conductive circuits.

[0058] The adapter 2 and the support 3 can be assembled from multiple plate structures and other components, and some or all of the adapter 2 and the support 3 can also be an integrated structure.

[0059] Please refer to Figure 8 and Figure 9 In one embodiment, the clamping member 21 is provided with an anti-slip structure so that the clamping member 21 can stably clamp the cable of the test earphone for a long time, ensuring the stability of the electrical connection between the cable of the test earphone and the test host 100.

[0060] The clamping structure of the clamping member 21 includes a first clamping member 211, a second clamping member 212, and an elastic member 213. The first clamping member 211 can be fixedly installed on the adapter 2 by means of screw connection or other means. The second clamping member 212 can be rotatably installed on the first clamping member 211 via a rotating shaft. The elastic member 213 can be an elastic structure such as a torsion spring. The elastic member 213 can be installed on the rotating shaft between the first clamping member 211 and the second clamping member 212, and the elastic member 213 is connected to the first clamping member 211 and the second clamping member 212 respectively.

[0061] The clamping member 21 has two clamping surfaces 21a arranged face to face. The first clamping member 211 and the second clamping member 212 each have a clamping surface 21a. The clamping surfaces 21a of the first clamping member 211 and the clamping surfaces 21a of the second clamping member 212 are used to clamp the cable of the test earphone.

[0062] The elastic member 213 is used to apply elastic force to close the clamping surfaces 21a of the first clamping member 211 and the second clamping member 212 to clamp the cable of the test earphone.

[0063] At least one of the clamping surfaces 21a of the first clamping member 211 and the second clamping member 212 is a non-smooth, anti-slip surface. Preferably, both the clamping surfaces 21a of the first clamping member 211 and the second clamping surface 21a of the second clamping member 212 are non-smooth, anti-slip surfaces, which provides better anti-slip effect and can better hold the test headphone cable. Alternatively, if the clamping surface 21a of the first clamping member 211 or the clamping surface 21a of the second clamping member 212 is a non-smooth, anti-slip surface, it can also prevent the test headphone cable from coming loose during the clamping process.

[0064] The anti-slip surface can be a serrated surface, a wavy surface, or other surfaces that form a toothed structure. When both the clamping surface 21a of the first clamping member 211 and the clamping surface 21a of the second clamping member 212 are anti-slip surfaces, the clamping surfaces 21a of the first clamping member 211 and the clamping surfaces 21a of the second clamping member 212 can be anti-slip surfaces with the same structure or anti-slip surfaces with different structures.

[0065] Under the elastic force of the elastic member 213, when the clamping surface 21a of the first clamping member 211 clamps the cable of the test earphone, the cable of the test earphone deforms under the anti-slip compression of the toothed structure. The clamping member 21 can clamp the cable of the test earphone more firmly, and the clamped cable is not easy to fall off.

[0066] Please refer to Figure 6 In one embodiment, the adapter 2 is further provided with a limiting member 214, which is located on both sides of the second clamping member 212. Specifically, the limiting member 214 is distributed on both sides of the second clamping member 212 along the axial direction of the rotation axis of the second clamping member 212. The limiting member 214 is used to limit the axial displacement of the second clamping member 212 along the rotation axis of the second clamping member 212 during the opening and closing process, so as to ensure the stability of the cable of the test earphone held by the first clamping member 211 and the second clamping member 212.

[0067] Specifically, the limiting member 214 forms a limiting groove 214a. The limiting member 214 is a partition structure with spaced intervals. The limiting groove 214a is formed in the middle of the partition structure. One end of the second clamping member 212 with a clamping surface 21a is located in the limiting groove 214a, and the limiting groove 214a has a certain depth, so that the end of the second clamping member 212 with a clamping surface 21a can always be located in the limiting groove 214a during the opening and closing process, so as to ensure that the second clamping member 212 will not deviate along the axial direction of the rotation axis of the second clamping member 212 during the opening and closing process.

[0068] The limiting member 214 can be installed on the side plate of the adapter 2, or it can be installed on both sides of the first clamping member 211; or the limiting member 214 can be integrated with the adapter 2 or the first clamping member 211, all of which can limit the axial offset of the second clamping member 212 along the rotation axis of the second clamping member 212.

[0069] The multiple second clamping members 212 are each provided with a limiting member 214 so that none of the second clamping members 212 will deviate along the axial direction of the rotation axis of the second clamping member 212 during the clamping process.

[0070] Please refer to Figure 10 and Figure 11 In one embodiment, the first adapter 22 and the second adapter 31 are rod-shaped or tubular electrical connection structures. One of the first adapter 22 and the second adapter 31 has a socket, and the other has a pin. The pin is inserted into the socket to achieve electrical connection between the first adapter 22 and the second adapter 31. For example, the lower end of the first adapter 22 has a socket, and the upper end of the second adapter 31 has a pin.

[0071] The lower part of the adapter 2 is provided with a mounting hole that penetrates the bottom plate of the adapter 2. The first adapter 22 is inserted into the mounting hole at the lower end of the adapter 2. The upper end of the first adapter 22 is electrically connected to the clamping member 21 through the first electrical connection line. The lower end of the first adapter 22 is electrically connected to the second adapter 31.

[0072] The first adapter 22 and the second adapter 31 are configured as a connection structure between the jack and the pin. The first adapter 22 and the second adapter 31 can be separated, so that the adapter 2 can be separated from the support 3. The adapter 2 can be removed from the support 3, and then the test earphone can be fixed and the test earphone cable can be clamped, which greatly facilitates the disassembly and assembly of the test earphone.

[0073] In other embodiments, the adapter 2 and the support 3 can also be configured as a fixed installation structure or an integrated structure. In this case, the first adapter 22 and the second adapter 31 can be simplified into a single conductive structure, or the first adapter 22 and the second adapter 31 can be configured as a threaded fixed connection structure.

[0074] Please refer to Figure 11 In one embodiment, the upper end of the first adapter 22 has a radially cut portion, which exposes the sidewall cut surface of the first adapter 22, forming a larger exposed area of ​​the first adapter 22, which can improve the stability of the plug-in or welded conductive connection between the first adapter 22 and the first electrical connection wire. For example, in the plug-in scheme, the upper end of the first adapter 22 forms a pointed structure, which can be used to insert into the connection terminal at the end of the first electrical connection wire, facilitating the insertion of the first adapter 22 and the first electrical connection wire; as another example, in the welding scheme, the upper end of the first adapter 22 forms a pointed structure, and when the first electrical connection wire is welded to the upper end of the first adapter 22, the first electrical connection wire can contact and weld together with the exposed sidewall cut surface of the upper end of the first adapter 22, which can effectively improve the stability of the welding between the first electrical connection wire and the first adapter 22. In one embodiment, the first adapter 22 and the second adapter 31 are in line contact. While ensuring good performance, the line contact can also reduce the friction between the two, making it easier to insert and separate the first adapter 22 and the second adapter 31. In other words, the line contact has both electrical stability and ease of insertion and removal.

[0075] Specifically, the ends of the ejector pins in the first adapter 22 and the second adapter 31 are set as spherical or arc-shaped surfaces. When the top of the ejector pin with a spherical or arc-shaped surface is inserted into the socket, the spherical or arc-shaped surface of the ejector pin forms an annular line contact with the inner wall of the socket, and there is a small frictional force. This ensures good electrical connection between the first adapter 22 and the second adapter 31, while facilitating the insertion, removal and disassembly of the first adapter 22 and the second adapter 31.

[0076] In one embodiment, the end faces of the insertion holes in the first adapter 22 and the second adapter 31 are inclined guide surfaces. During the insertion process of the first adapter 22 and the second adapter 31, the guide surfaces can guide the end of the pin to be inserted into the insertion hole, reducing the difficulty of forming an electrical connection when the adapter 2 and the support 3 are installed.

[0077] In one embodiment, the end of the second adapter 31 with a spherical or arcuate surface is floating relative to the main body, and a spring is provided between the end with the spherical or arcuate surface and the main body. The spring provides an upward elastic force to the end with the spherical or arcuate surface, so that after the first adapter 22 and the second adapter 31 are connected, the spring can drive the second adapter 31 to move toward the first adapter 22, thereby improving the stability of the electrical connection between the two.

[0078] In one embodiment, the mounting base 1 and the adapter base 2 are detachably connected, and the mounting base 1 and the adapter base 2 are separately configured. The mounting base 1 can be set as a dedicated component, with different mounting bases 11 corresponding to different headphones. The adapter base 2 is set as a universal component, and one adapter base 2 can be adapted to install multiple mounting bases 1 for installing different headphones. This configuration can meet the needs of fixing and testing different headphones, and also reduce costs.

[0079] Mounting base 1 and adapter base 2 can be detachably connected by snap-fit, magnetism, or other means. The snap-fit ​​and magnetism structures are used for positioning, enabling quick and accurate installation of mounting base 1 and adapter base 2.

[0080] A foolproof structure may also be provided between the mounting base 1 and the adapter 2 to limit the installation orientation of the mounting base 1 relative to the adapter 2, so that the headphone fixing position 11 of the mounting base 1 is aligned with the orientation of the clamping member 21 of the adapter 2.

[0081] In other embodiments, the mounting base 1 and the adapter base 2 can also be fixedly connected by screws or other means to enable testing of a specific type of headphone. Alternatively, the headphone fixing position 11 of the mounting base 1 can be configured as an adjustable structure to accommodate different headphones and meet the testing needs of various headphones.

[0082] In one embodiment, the adapter 2 and the support 3 can also be detachable. This configuration allows the mounting base 1 and the adapter 2 to be disassembled away from the support 3, and the test headphones can be installed and removed from a position away from the support 3. In particular, when the support 3 is fixedly installed in the test chamber 300, the test headphones can be removed from outside the test chamber 300, which greatly facilitates the installation and removal of the test headphones and improves testing efficiency.

[0083] Please refer to Figure 10 In one embodiment, a positioning structure is provided between the adapter 2 and the support 3 so that the first adapter 22 and the second adapter 31 can be aligned and connected during the assembly process of the adapter 2 and the support 3.

[0084] The bottom surface of the adapter 2 is provided with at least one first positioning part 23, and the top surface of the support 3 is provided with at least one second positioning part 32. The first positioning part 23 and the second positioning part 32 correspond one-to-one. Specifically, the number of first positioning parts 23 and the second positioning part 32 are the same, their positions correspond, and their structures are complementary. For example, the first positioning part 23 and the second positioning part 32 are a combination of a socket and a pin, or a combination of a protrusion and a groove. The socket and pin, or the protrusion and groove, can be set as irregular structures so that the socket and pin, or the protrusion and groove, not only have a positioning function, but also a foolproof function. For example, a semi-circular protrusion is provided on one side of the lower end of the adapter 2, and correspondingly, a semi-circular groove is provided on one side of the upper surface of the support 3. In this way, the semi-circular protrusion and groove can play a positioning and foolproof role, preventing the adapter 2 from being installed in the wrong direction.

[0085] In one embodiment, the first positioning part 23 and the second positioning part 32 can also be magnetically attracted to each other. For example, the first positioning part 23 and the second positioning part 32 can be magnetic blocks with opposite magnetic properties, or one of the first positioning part 23 and the second positioning part 32 can be a magnetic block and the other can be a magnetically attracted metal block, and the face-to-face connection surfaces of the adapter 2 and the support 3 are made of non-magnetic material. With this configuration, the magnetic attraction of the first positioning part 23 and the second positioning part 32 can also be used to position and assemble the adapter 2 and the support 3; the magnetic attraction can also play a guiding role. When the worker places the adapter 2 at a position approximately above the support 3, the magnetic attraction between the first positioning part 23 and the second positioning part 32 can guide the adapter 2 to the corresponding position on the support 3, greatly improving the accuracy and efficiency of the assembly of the adapter 2 and the support 3.

[0086] In one embodiment, the first positioning part 23 and the second positioning part 32 may further include one or more of the following: a combination of a socket and a pin, a combination of a protrusion and a groove, and a magnetic combination. By cooperating with various different positioning components, the stability of the assembly of the adapter 2 and the support 3 can be improved.

[0087] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art can make various simple deductions, modifications, or substitutions based on the concept of this invention.
