Description

Technical Field

[0001] The present application relates to the technical field of loudspeaker fixtures, and in particular to a V-shaped insert-type line adjustment fixture. Background Art

[0002] The voice coil of the speaker needs to be connected to the external electrical signal through a wire. As the voice coil vibrates, the end of the wire connected to the voice coil will also vibrate along with the voice coil, while the other end of the wire is usually fixed to a terminal board set on the speaker bracket. This requires that the wire must have a certain vibration length. Therefore, before welding the wire to the terminal board, it is necessary to adjust the wire so that the wire maintains an arc, so that the wire has a certain margin in length to follow the vibration of the voice coil, while not hitting the drum paper (i.e., paper cone) of the speaker due to being too long. Summary of the invention

[0003] The main technical problem solved by the present application is to provide a V-shaped plug-in wire adjustment fixture for adjusting the curvature of the speaker's silk cable and ensuring that the silk cable will not rebound or fall off after adjustment, thereby meeting the speaker's wire adjustment requirements and the speaker's sound quality performance requirements.

[0004] A V-shaped insert-type wire adjusting fixture proposed in an embodiment of the present application includes: a V-shaped fixture body provided with a V-shaped groove, a movable rod rotatably connected to the V-shaped fixture body through a combination pin, and an opening spring connected between the V-shaped fixture body and the movable rod; wherein the V-shaped groove is opened along the length direction of the V-shaped fixture body; wherein the movable rod is used to clamp and fix the lead passing through the V-shaped groove when it is in an initial position, and release the lead when it leaves the initial position; wherein the opening spring is used to provide a restoring force that urges the movable rod to return to the initial position when the movable rod rotates away from the initial position.

[0005] In some optional embodiments, the V-shaped fixture body is a long strip structure, and the V-shaped groove includes a V-shaped opening and a long groove connected thereto.

[0006] In some optional embodiments, the length of the V-shaped groove is greater than 1 / 2 of the length of the V-shaped fixture body and less than 4 / 5 of the length of the V-shaped fixture body.

[0007] In some optional embodiments, the movable rod is parallel to the long slot and at least partially covers the long slot in an initial position.

[0008] In some optional embodiments, the combination pin is located on an extension line of the long slot.

[0009] In some optional embodiments, the center of the combination pin deviates from the center line of the long slot.

[0010] In some optional embodiments, a U-shaped opening is provided on the other end of the V-shaped fixture body opposite to the V-shaped groove.

[0011] In some optional embodiments, the movable rod includes a functional segment located on one side of the combination pin and a handle segment located on the other side of the combination pin, the width of the handle segment is greater than the width of the functional segment, the functional segment is used to cooperate with the V-groove to clamp and fix the lead, and the handle segment is used for an operator to operate.

[0012] In some optional embodiments, the opening spring includes a first spring sheet connected to the V-shaped fixture body and a second spring sheet connected to the movable rod. When the movable rod is forced to rotate away from the initial position, the second spring sheet is forced to approach the first spring sheet, thereby generating an elastic restoring force that forces the movable rod to return to the initial position.

[0013] In some optional embodiments, the V-shaped plug-in wire adjustment fixture is used for speaker wire adjustment, and the V-shaped fixture body is inserted between the speaker bracket and the terminal board, so that the speaker lead passes through the V-shaped groove.

[0014] It can be seen from the above technical solutions that the embodiments of the present application have the following advantages:

[0015] The present application proposes a V-shaped plug-in wire adjustment fixture, which can be used to adjust the curvature of the speaker lead wire (i.e., brocade wire). The present application sets a V-shaped fixture body, a movable rod, and an opening spring to cooperate with each other, and can use the V-shaped fixture body to adjust the curvature of the speaker's brocade wire, and can use the movable rod to clamp and fix the brocade wire that has completed the curvature adjustment, thereby meeting the demand for adjusting the curvature of the speaker's brocade wire, improving the common wire adjustment problems in the speaker industry, and ensuring that the brocade wire will not rebound or even fall off after the wire adjustment, thereby meeting the sound quality performance requirements of the speaker, reducing the poor sound quality caused by brocade wire problems, and improving product quality and yield.

[0016] The general plug-in wire adjustment jig often fails to accurately insert the silk thread into place during use, and the silk thread often rebounds or falls off after the wire adjustment is completed during the production process. As a result, the reserved silk thread curvature is too long, and the silk thread hits the drum paper (i.e., paper cone) during the test after the product is completed, resulting in poor wire bonding, which leads to low efficiency and yield, and the inability to ensure the consistency and stability of the curvature of the silk thread. The present application can clamp and fix the silk thread by adding a movable rod, which can prevent the silk thread from rebounding and falling off, ensure that the curvature of the silk thread meets the requirements, eliminate poor wire bonding of the silk thread, ensure the consistency and stability of the curvature of the silk thread, and improve the product yield and efficiency.

[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only embodiments of a part of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0022] The terms "first", "second", "third", etc. in the specification and claims of this application and the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0023] The following describes the embodiments in detail.

[0024] refer to Figures 1 to 3, an embodiment of the present application proposes a V-shaped plug-in wire adjustment fixture. The fixture can be used to adjust the lead wire of the speaker voice coil, so that the lead wire maintains an arc when welded to the terminal board of the speaker, so that there is a certain margin in length to follow the vibration of the voice coil, and at the same time it will not hit the drum paper (i.e., paper cone) of the speaker due to being too long. The lead wire mentioned here can be a brocade wire, which is generally used as the lead wire of the voice coil in the industry. Exemplarily, the brocade wire can include conductive wires (such as copper, silver, etc.) and textile wires (such as cotton wire, Nomex, etc.), and the wire body can be processed (such as waxing, heat shrink tubing, silicone coating, etc.).

[0025] like Figures 1 to 3 As shown, the V-shaped insert-type line adjusting jig of the embodiment of the present application may include: a V-shaped jig body 10, a movable rod 20, a combination pin 30 and an opening spring 40, wherein the V-shaped jig body 10 is provided with a V-shaped groove 11, the movable rod 20 is rotatably connected to the V-shaped jig body 10 through the combination pin 30, and the opening spring 40 is connected between the V-shaped jig body 10 and the movable rod 20.

[0026] The V-shaped fixture body 10 may be a long strip structure, the V-shaped groove 11 is opened along the length direction of the V-shaped fixture body 10, and the movable rod 20 is substantially parallel or nearly parallel to the length direction of the V-shaped fixture body 10 when located at the initial position.

[0027] Among them, the V-shaped jig body 10 can be inserted between the speaker bracket (i.e., the basin frame) and the terminal board, the voice coil of the speaker is located inside the bracket, and the lead wire of the voice coil (such as a silk thread) can pass through the V-shaped groove 11 of the V-shaped jig body 10 and then be inserted into the terminal board to complete the welding with the terminal board. Here, the function of the V-shaped jig body 10 and its V-shaped groove 11 is to form an arc for the lead wire of the voice coil and maintain the arc during welding. Here, the V-shaped jig body 10 can also play a blocking and protective role to prevent the solder from splashing into the bracket during welding and damaging the voice coil, drum paper, etc. Here, the V-shaped jig body 10 is the main part of the entire jig, which supports other parts. The height and other dimensions of the V-shaped jig body 10 can be determined according to the size of the applicable speaker bracket (i.e., the basin frame).

[0028] Among them, the movable rod 20 is used to clamp and fix the lead passing through the V-shaped groove 11 when it is in the initial position, so as to fix the lead forming an arc and prevent the lead from rebounding or even falling, thereby meeting the consistency requirement; the movable rod 20 is also used to release the lead when leaving the initial position, at which time the lead can be taken out of the V-shaped groove 11, or the lead can be placed in the V-shaped groove 11.

[0029] The opening spring 40 is used to provide a restoring force to urge the movable rod 20 to return to the initial position when the movable rod 20 rotates away from the initial position, so that the operator only needs to release the movable rod 20 after inserting the lead into the V-shaped groove 11 and adjusting the curvature, and the movable rod 20 will return to the initial position under the action of the opening spring 40 to clamp and fix the lead. Here, the opening spring 40 is used to bear the force of the V-shaped fixture body 10 and the movable rod 20, bear the series connection between the two, and play the role of elastic force and force expansion.

[0030] The combination pin 30 is used to fix the movable rod and the fixture body, so that the movable rod 20 can move on the V-shaped fixture body 10 in a rotational manner.

[0031] In some optional embodiments, the V-shaped fixture body 10 is, for example, a long strip-shaped structure extending laterally, and the V-shaped groove 11 may include a V-shaped opening 111 and a long groove 112 connected to the V-shaped opening 111. The V-shaped opening 111 is the largest at the edge of the V-shaped fixture body 10 (for example, the left edge), and the width becomes narrower as it moves toward the inside of the V-shaped fixture body 10 (for example, to the right), until the width is reduced to the same width as the long groove 112 and connected, and the long groove 112 continues to extend to the right. Here, the V-shaped opening 111 can satisfy the function of quickly inserting the brocade thread into the groove (i.e., inserting it into the long groove 112).

[0032] In some optional embodiments, the length of the V-shaped groove 11 can be greater than 1 / 2 of the length of the V-shaped fixture body 10, and can be less than 4 / 5 (or 3 / 4) of the length of the V-shaped fixture body 10 regardless of passing through the V-shaped fixture body 10. In this way, when the V-shaped fixture body 10 is inserted into the speaker, the terminal board can be located at or close to the center of the V-shaped fixture body 10.

[0033] In some optional embodiments, the movable rod 20 is, for example, a long rod extending laterally, which is parallel to the long slot 112 and at least partially covers the long slot 112 or completely covers the long slot 112 in the initial position, that is, the movable rod 20 can fully or partially block the long slot 112 in the initial position, thereby clamping the lead wire.

[0034] In some optional embodiments, the combination pin 30 is located on the extension line of the long slot 112 , and the V-shaped opening 111 , the long slot 112 and the combination pin 30 are arranged from left to right, wherein the combination pin 30 and the long slot 112 are spaced apart.

[0035] In some optional embodiments, the center of the combination pin 30 deviates from the center line of the long slot 112, for example, deviates downward, for example, is located between the center line and the lower edge line of the long slot 112. In this way, after the movable rod 20 is installed, the center line of the movable rod 20 will also deviate from the center line of the long slot 112, so that it can play the role of clamping and fixing the lead wire, but will not be clamped too tightly to damage the lead wire.

[0036] In some optional embodiments, a U-shaped opening 12 is provided at the other end of the V-shaped fixture body 10 opposite to the V-shaped groove 11. The U-shaped opening 12 can facilitate the setting of the opening spring 40 and facilitate operation.

[0037] In some optional embodiments, the movable rod 20 includes a functional segment 21 located on one side of the combination pin 30 and a handle segment 22 located on the other side of the combination pin 30. The width of the handle segment 22 is greater than the width of the functional segment 21. The functional segment 21 can be used to cooperate with the V-groove 11 to clamp and fix the lead, and the handle segment 22 can be used for operation by an operator.

[0038] In some optional embodiments, the opening spring 40 includes a first spring piece 41 connected to the V-shaped fixture body 10 and a second spring piece 42 connected to the movable rod 20. When the movable rod 20 is forced to rotate away from the initial position, the second spring piece 42 is forced to approach the first spring piece 41, thereby generating an elastic restoring force (i.e., rebound force) that causes the movable rod 20 to return to the initial position.

[0039] As described above, the embodiment of the present application proposes a V-shaped insert-type wire adjustment jig, which has a V-shaped jig body 10 as the main part. The V-shaped jig body 10 can be used to adjust the curvature of the voice coil lead (i.e., the silk thread) of the speaker, and the opening of the V-shaped jig body 10 is improved to a V-shaped opening 111 to facilitate the insertion and passage of the silk thread; in addition, components such as a movable rod 20, a combination pin 30 and an opening spring 40 are added to form a V-shaped insert-type wire adjustment jig; the wire adjustment requirements of the speaker can be met, and the silk thread can be fixed after the curvature adjustment of the silk thread is completed, which solves the problem of rebound and falling of the silk thread after the wire adjustment is completed in the industry; the jig of the present application has a wider application range, stronger versatility, more stable consistency, easier use and higher efficiency; the jig of the present application can be applied to the wire adjustment of speakers of various sizes.

[0040] The working principle of the present application is that the V-shaped fixture body 10 is inserted into a fixed position inside the brocade wire, and the movable rod 20 prevents the position of the brocade wire from changing. The operation steps are to press and open the movable rod 20, and insert the V-shaped fixture body 10 into the brocade wire through the V-shaped opening 111. After being inserted, release the pressure and use the rebound force of the opening spring 40 to clamp the movable rod 20 to the brocade wire. Then the soldering operation can be carried out. The fixture of the present application meets the function of fixing the brocade wire, so that the brocade wire is fixed in its effective position, so that the brocade wire will not rebound or fall off during soldering, which solves the problem of frequent wire hitting in the speaker industry, and has strong stability and practicality, which can greatly improve the yield and stability of the product.
