Abstract
Description
Technical Field
[0001] This application relates to the technical field of speaker fixtures, and particularly to a V-shaped insert type wire adjustment fixture. Background Art
[0002] The voice coil of a speaker needs to be connected to an external electrical signal through a brocade wire. Due to the vibration of the voice coil, one end of the brocade wire connected to the voice coil will also vibrate with the voice coil, while the other end of the brocade wire is usually fixed on a terminal board provided on the speaker bracket. This requires that the brocade wire must have a certain vibration length. Therefore, before welding the brocade wire to the terminal board, wire adjustment is required to make the brocade wire maintain an arc, so that the brocade wire can have a certain margin in length to follow the vibration of the voice coil, and at the same time will not touch and hit the speaker's diaphragm (i.e., the paper cone) because it is too long. Utility Model Content
[0003] The main technical problem to be solved by this application is to provide a V-shaped insert type wire adjustment fixture, which is used to adjust the arc of the brocade wire of the speaker and ensure that the brocade wire will not rebound or fall off after wire adjustment, so as to meet the wire adjustment requirements of the speaker and the sound quality performance requirements of the speaker.
[0004] A V-shaped insert type wire adjustment fixture proposed in an embodiment of this application includes: a V-shaped fixture main body provided with a V-shaped groove, a movable rod rotatably connected to the V-shaped fixture main body through a combination pin, and an open spring connected between the V-shaped fixture main body and the movable rod; wherein, the movable rod is used to clamp and fix the lead wire passing through the V-shaped groove when in the initial position, and release the lead wire when leaving the initial position; wherein, the open 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 main 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 main body and less than 4 / 5 of the length of the V-shaped fixture main body.
[0007] In some optional embodiments, the movable rod is parallel to the long groove and at least partially covers the long groove when in the initial position.
[0008] In some optional embodiments, the combination pin is located on the extension line of the long groove.
[0009] In some optional embodiments, the center of the combination pin deviates from the center line of the long groove.
[0010] In some alternative embodiments, a U-shaped opening is provided at the other end of the V-shaped fixture body opposite to the V-shaped groove.
[0011] In some alternative embodiments, the movable rod includes a functional section on one side of the combination pin and a handle section on the other side of the combination pin. The width of the handle section is greater than that of the functional section. The functional section is used to cooperate with the V-shaped groove to clamp and fix the lead wire, and the handle section is used for an operator to operate.
[0012] In some alternative embodiments, the opening spring includes a first elastic sheet connected to the V-shaped fixture body and a second elastic sheet connected to the movable rod. When the movable rod is forced to rotate away from the initial position, the second elastic sheet is forced to approach the first elastic sheet, thereby generating an elastic restoring force that urges the movable rod to return to the initial position.
[0013] In some alternative embodiments, the V-shaped insert type wire adjustment fixture is used for adjusting the wires of a speaker. The V-shaped fixture body is inserted between the bracket and the terminal board of the speaker, and the lead wire of the speaker 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 insert type wire adjustment fixture, which can be used to adjust the arc of the lead wire (i.e., brocade silk wire) of a speaker. By arranging the V-shaped fixture body, the movable rod and the opening spring to cooperate with each other, the present application can adjust the arc of the brocade silk wire of the speaker by using the V-shaped fixture body, and can clamp and fix the brocade silk wire with the arc adjusted by using the movable rod, so as to meet the requirement of adjusting the arc of the brocade silk wire of the speaker, improve the common problem of wire adjustment in the speaker industry, ensure that the brocade silk wire will not rebound or even fall off after wire adjustment, thereby meeting the sound quality performance requirements of the speaker, reducing the sound quality problems caused by the brocade silk wire, and improving the product quality and yield.
[0016] For a general insert type wire adjustment fixture, during use, it often occurs that the wire adjustment fixture cannot accurately align and insert the brocade silk wire in place, and during the production process, the brocade silk wire often rebounds and falls off after wire adjustment. Therefore, the reserved arc of the brocade silk wire is too long, and during the test process after the product is completed, the brocade silk wire hits the drum paper (i.e., the paper cone), resulting in poor wire connection, low efficiency and low yield, and the consistency and stability of the arc of the brocade silk wire cannot be guaranteed. By adding a movable rod, the present application can clamp and fix the brocade silk wire, avoid the rebound and fall of the brocade silk wire, ensure that the arc of the brocade silk wire meets the requirements, eliminate the poor wire connection of the brocade silk wire, ensure the consistency and stability of the arc of the brocade silk wire, and improve the product yield and efficiency.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.
[0022] The terms "first", "second", "third", etc. in the specification, claims and drawings of the present application are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion. 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 further includes steps or units not listed, or optionally further includes other steps or units inherent to these processes, methods, products or devices.
[0023] The following will be described in detail through specific embodiments respectively.
[0024] Reference Figures 1 to 3, an embodiment of the present application provides a V-shaped insert type wire adjustment jig. This jig can be used to adjust the wires of the lead wires of the speaker voice coil, so that the lead wires maintain 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 speaker drum paper (i.e., the paper cone) because it is too long. The lead wires mentioned here can be brocade silk wires, and brocade silk wires are usually used as the lead wires of the voice coil in the industry. Exemplarily, the brocade silk wire can include a wire (such as copper, silver, etc.) and a textile wire (such as cotton thread, Nomex, etc.), and the wire body can be processed (such as waxing, heat shrinkable tube, silicone coating, etc.).
[0025] As Figures 1 to 3 shown, the V-shaped insert type wire adjustment 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. Among them, the V-shaped jig body 10 is provided with a V-shaped groove 11, and 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] Among them, the V-shaped jig body 10 may be a long strip structure, the V-shaped groove 11 may be opened along the length direction of the V-shaped jig body 10, and the movable rod 20 may be substantially parallel or nearly parallel to the length direction of the V-shaped jig body 10 when in the initial position.
[0027] Among them, the V-shaped jig body 10 can be inserted between the bracket (i.e., the chassis) of the speaker and the terminal board. The voice coil of the speaker is located inside the bracket, and the lead wires (such as brocade silk wires) of the voice coil 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 make the lead wires of the voice coil form an arc and maintain this arc during welding. Here, the V-shaped jig body 10 can also play a role of blocking and protecting, preventing the solder during welding from splashing into the bracket and damaging the voice coil, drum paper, etc. Here, the V-shaped jig body 10 is the main body part of the entire jig and plays a supporting role for 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 chassis).
[0028] Among them, the movable rod 20 is used to clamp and fix the lead wire passing through the V-shaped groove 11 when in the initial position, so as to fix the lead wire forming an arc, prevent the lead wire from rebounding or even falling off, and meet the consistency requirements; the movable rod 20 is also used to release the lead wire when leaving the initial position. At this time, the lead wire can be taken out of the V-shaped groove 11, or the lead wire can be put into the V-shaped groove 11.
[0029] Among them, the opening spring 40 is used to provide a restoring force that urges the movable rod 20 to return to the initial position when the movable rod 20 rotates away from the initial position. In this way, after the operator inserts the lead wire into the V-shaped groove 11 and adjusts the arc, the operator only needs to release the movable rod 20, 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 wire. Here, the opening spring 40 is used for the V-shaped fixture main body 10 and the movable rod 20 to bear the force, carry the series connection between the two, and play the role of elastic force and telescopic force.
[0030] Among them, the combination pin 30 is used to fix the movable rod and the fixture main body, so that the movable rod 20 can move on the V-shaped fixture main body 10 in a rotational manner.
[0031] In some alternative embodiments, the V-shaped fixture main body 10 is, for example, a long strip structure extending horizontally. 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 has the largest opening at the edge of the V-shaped fixture main body 10 (for example, the left edge), and the width becomes narrower as it goes deeper into the V-shaped fixture main body 10 (for example, to the right), until the width is reduced to the same as the width of the long groove 112 and they are connected. The long groove 112 continues to extend to the right. Here, the V-shaped opening 111 can serve to quickly insert the brocade silk thread into the groove (that is, snap into the long groove 112).
[0032] In some alternative embodiments, the length of the V-shaped groove 11 can be greater than 1 / 2 of the length of the V-shaped fixture main body 10, and regardless of passing through the V-shaped fixture main body 10, for example, less than 4 / 5 (or 3 / 4) of the length of the V-shaped fixture main body 10. In this way, when the V-shaped fixture main body 10 is inserted into the speaker, the terminal board can be located at or near the center of the V-shaped fixture main body 10.
[0033] In some alternative embodiments, the movable rod 20 is, for example, a long rod extending horizontally. In the initial position, it is parallel to the long groove 112 and at least partially covers the long groove 112 or completely covers the long groove 112. That is, the movable rod 20 can completely or partially block the long groove 112 in the initial position, thereby clamping and fixing the lead wire.
[0034] In some alternative embodiments, the combination pin 30 is located on the extension line of the long groove 112. The V-shaped opening 111, the long groove 112, and the combination pin 30 are arranged from left to right in this order. Among them, the combination pin 30 and the long groove 112 are spaced apart.
[0035] In some alternative embodiments, the center of the combination pin 30 deviates from the center line of the long groove 112, for example, downward, for example, located between the center line of the long groove 112 and the lower edge line. 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 groove 112. Thus, it can both play the role of clamping and fixing the lead wire and not clamp too tightly to damage the lead wire.
[0036] In some alternative embodiments, at the other end of the V-shaped jig body 10 opposite to the V-shaped groove 11, there is a U-shaped opening 12. The U-shaped opening 12 can facilitate the setting of the opening spring 40 and facilitate operation, etc.
[0037] In some alternative embodiments, the movable rod 20 includes a functional section 21 on one side of the combination pin 30 and a handle section 22 on the other side of the combination pin 30. The width of the handle section 22 is greater than the width of the functional section 21. The functional section 21 can be used to cooperate with the V-shaped groove 11 to clamp and fix the lead wire, and the handle section 22 can be used for the operator to operate.
[0038] In some alternative embodiments, the opening spring 40 includes a first elastic piece 41 connected to the V-shaped jig body 10 and a second elastic piece 42 connected to the movable rod 20. When the movable rod 20 is forced to rotate away from the initial position, the second elastic piece 42 is forced to approach the first elastic piece 41, thereby generating an elastic restoring force (i.e., a resilience force) that urges the movable rod 20 to return to the initial position.
[0039] As mentioned above, the embodiment of the present application proposes a V-shaped insert type wire adjusting jig. The jig takes the V-shaped jig body 10 as the main part. The V-shaped jig body 10 can be used to adjust the arc of the voice coil lead wire (i.e., the brocade silk thread) of the speaker, and the opening of the V-shaped jig body 10 is improved to be a V-shaped opening 111 to facilitate the insertion and passing of the brocade silk thread; in addition, components such as a movable rod 20, a combination pin 30, and an opening spring 40 are added to jointly form a V-shaped insert type wire adjusting jig; it can meet the wire adjusting requirements of the speaker, can fix the brocade silk thread after the arc adjustment of the brocade silk thread is completed, and solves the problems of the rebound and dropping of the brocade silk thread in the industry after the wire adjustment is completed; the jig of the present application has a wider application range, stronger versatility, more stable consistency, is easier to use, and has higher efficiency; the jig of the present application can be applied to the wire adjustment of various sizes of speakers.
[0040] The working principle of the present application is that the V-shaped jig body 10 is inserted into the brocade silk thread to fix the position. The movable rod 20 keeps the position of the brocade silk thread unchanged. The operation steps are to press and open the movable rod 20, and through the V-shaped opening 111, the V-shaped jig body 10 is clamped into the brocade silk thread. After clamping, release the pressing, and use the resilience force of the opening spring 40 to make the movable rod 20 clamp the brocade silk thread tightly, and then the soldering operation can be carried out. The jig of the present application satisfies the function of fixing the brocade silk thread, fixes the brocade silk thread in its effective position, and prevents the brocade silk thread from rebounding and falling during soldering, solves the problem of frequent wire tying of the brocade silk thread in the speaker industry, and has strong stability and practicability, and can greatly improve the yield and stability of the product.

In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not described in detail in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.
