Description

Technical Field

[0001] The present application belongs to the technical field of loudspeaker tooling and fixtures, and relates to a tooling and fixture for loudspeaker line adjustment, and specifically to a gravity-type line adjustment tooling for a loudspeaker. Background Art

[0002] A loudspeaker is a transducer device that converts electrical signals into sound signals. The speaker uses electromagnetic, piezoelectric or electrostatic effects to make its cone vibrate and resonate with the surrounding air to produce sound. The speaker can be installed in home TVs, multimedia home audio, outdoor audio, cars, KTV venues, square broadcasts, computers, etc., as a sound unit.

[0003] Most speakers use leads to transmit signals, and usually use silk wire as the lead. The two ends of the silk wire are connected to the voice coil and terminal board of the speaker respectively. The terminal board is generally fixed on the outside of the speaker's basin frame. During the operation of the speaker, the vibration of the voice coil will drive the silk wire to vibrate. In order to avoid problems such as wire hitting (the silk wire hits the paper basin), it is necessary to design a tooling fixture to adjust the silk wire during the assembly process of the speaker, that is, adjust the curvature of the silk wire to reserve a certain length, and then weld the silk wire to the terminal board after the adjustment is completed.

[0004] At present, the tooling and fixtures used for line adjustment in the industry are usually mainly plug-ins and plug-ins, and the line adjustment operation relies on the experience of the operator. It is often the case that the adjustment is not in place and the line adjustment curvature is inconsistent, resulting in the undesirable situation of inconsistent curvature of the silk wire and abnormal sound of the wire punching, which greatly reduces the yield of the product. Summary of the invention

[0005] The main technical problem solved by the present application is to provide a gravity-type wire adjustment tool for a speaker, which is used to adjust the curvature of the silk wire of the speaker and improve the consistency of the wire adjustment curvature to meet the sound quality performance requirements of the speaker.

[0006] The present application proposes a gravity-type line adjustment tool for a speaker, comprising: a fixture body, including a top surface, a long groove arranged at the front end of the top surface, and a through hole arranged in the middle of the top surface, the top surface is used to carry a speaker assembly, the speaker assembly includes a basin frame, a voice coil and a silk thread, and the through hole is used to avoid the voice coil; two positioning rotating blocks are arranged in the long groove, the positioning rotating blocks are rotatable, and the top of the positioning rotating blocks is convexly provided with a positioning pressure column located on the outside and a curvature adjustment block located on the inside, and the outer side of the positioning rotating block is upwardly tilted in a natural state; when the speaker assembly is placed on the top surface, the positioning hole of the speaker assembly is sleeved on the positioning pressure column and the speaker assembly presses down the outer side of the positioning rotating block, so that the positioning rotating block rotates outward, driving the curvature adjustment block on the positioning rotating block to move, and adjusting the curvature of the silk thread leaning against the outer side of the curvature adjustment block.

[0007] In some optional embodiments, the positioning rotating block is rotatably disposed in the long slot via a combination pin penetrating the long slot.

[0008] In some optional embodiments, the length of the long slot extends in the left-right direction, and the two positioning rotating blocks are symmetrically arranged in the long slot, one on the left and one on the right.

[0009] In some optional embodiments, the fixture body includes a limiting boss disposed at the rear end of the top surface, and the limiting boss is used to block and limit the speaker assembly.

[0010] In some optional embodiments, the limiting boss has two limiting surfaces on one side relative to the through hole, the two limiting surfaces form a V-shaped groove, and the basin frame is inserted into the V-shaped groove and contacts the two limiting surfaces.

[0011] In some optional embodiments, the top surface is an inclined surface with a higher front end and a lower rear end. When the speaker assembly is placed on the top surface, the speaker assembly approaches the limiting boss under the action of gravity.

[0012] In some optional embodiments, the midpoint of the line connecting the centers of the two positioning rotating blocks, the center of the through hole and the vertex of the V-shaped groove are located on the same straight line, and the straight line is perpendicular to the extension direction of the length of the long groove.

[0013] In some optional embodiments, the positioning rotating block has a mounting hole sleeved on the combination pin, and the mounting hole is close to the inner side edge of the positioning rotating block and away from the outer side edge.

[0014] In some optional embodiments, the positioning pressure column is vertically arranged on the upper surface of the positioning rotating block, and the curvature adjustment block is inclined toward the outside on the upper surface of the positioning rotating block.

[0015] In some optional embodiments, when the positioning rotating block is rotated outward to a preset angle, the upper surface of the positioning rotating block is flush with the top surface.

[0016] It can be seen from the above technical solutions that the embodiments of the present application have the following advantages:

[0017] The present application sets a rotatable positioning rotating block with a positioning pressure column and an arc adjustment block in the long groove of the fixture body, so that after the speaker assembly is placed on it, it will be positioned by the positioning pressure column and rely on its own gravity to press down the positioning rotating block to rotate, thereby driving the arc adjustment block to move to a preset position to achieve the arc adjustment of the brocade wire. In this way, the use of gravity-type pressing to adjust the consistency of the brocade wire arc is achieved, and the consistency of the brocade wire arc adjustment is ensured by the consistency of the speaker assembly's own weight, and there will be no excessive line adjustment actions (the operator only needs to place the speaker assembly on the fixture to rely on gravity to complete the line adjustment by itself, and the operator does not need to make more actions). Therefore, while meeting the line adjustment requirements, the consistency and efficiency of the line adjustment are improved, and the sound quality performance requirements of the speaker can be met with high standards, avoiding the occurrence of problems such as brocade wire hitting, and improving the yield and stability of the product.

[0018] There are many types of tooling and jigs for line adjustment in the speaker industry, but none of them rely on gravity for line adjustment. This application proposes a gravity-type line adjustment tooling for speakers, which breaks through the limitations of traditional tooling and jigs that use rods and sheets, meets the line adjustment requirements of speakers, achieves a high consistency in the line adjustment curvature, and improves the efficiency of line adjustment operations.

[0019] This application innovatively proposes a gravity-type line adjustment tooling for loudspeakers. Due to the above advantages, it has a wider range of applications in the loudspeaker industry, stronger versatility, more stable consistency, easier use, and higher efficiency.

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.

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.

[0030] The following describes the embodiments in detail.

[0031] refer to Figures 1 to 6The embodiment of the present application provides a gravity-type wire adjustment tool for a speaker (hereinafter referred to as the wire adjustment tool or tool), which is applied to the wire adjustment process of the speaker's silk thread to adjust the curvature of the silk thread to ensure the consistency of the curvature of the silk thread after the adjustment. The silk thread is neither too short to affect the vibration of the voice coil of the connected speaker, nor too long to cause the problem of hitting the speaker's paper cone when following the vibration of the voice coil.

[0032] like Figures 1 to 6 As shown, the line adjustment tool of this application includes:

[0033] The fixture body 10 includes a top surface 101, a long groove 102 disposed at the front end of the top surface 101, and a through hole 103 disposed in the middle of the top surface 101. The top surface 101 is used to carry a speaker assembly, the speaker assembly includes a basin frame, a voice coil and a silk thread, and the through hole 103 is used to avoid the voice coil;

[0034] Two positioning rotating blocks 20 are arranged in the long slot 102. The positioning rotating blocks 20 are rotatable. The top of the positioning rotating blocks 20 is convexly provided with a positioning pressure column 201 located on the outside and a curvature adjustment block 202 located on the inside. In a natural state, the outer side of the positioning rotating block 20 is upwardly tilted, and the outer positioning pressure column 201 is higher than the curvature adjustment block 202.

[0035] When the speaker assembly is placed on the top surface 101, its basin frame is supported and fixed on the top surface 101, the terminal board on the basin frame faces the front end, the voice coil falls into the through hole 103, the positioning turn block 20 extends into the basin frame from the bottom of the basin frame, and the two silk threads (one positive and one negative) connected to the voice coil are respectively against the outside of the two curvature adjustment blocks 202 (between the curvature adjustment block 202 and the positioning pressure column 201), the positioning hole of the speaker assembly (the positioning hole is located on the basin frame) is sleeved on the positioning pressure column 201 and the speaker assembly presses down the outside of the positioning turn block 20, so that the positioning turn block 20 rotates outward, driving the curvature adjustment block 202 on the positioning turn block 20 to move upward and outward, and adjusting the curvature of the silk thread against the outside of the curvature adjustment block 202.

[0036] Here, the speaker assembly mentioned may be a semi-finished assembly that has completed the assembly of the vibration system (for example, including a voice coil, a paper cone, a spring, etc.) and the basin frame, but has not yet installed the magnetic system (for example, including a magnet, a washer, a U-iron or a T-iron, etc.).

[0037] In some optional embodiments, the positioning rotating block 20 is rotatably arranged in the long slot 102 by means of a combination pin 30 that penetrates the long slot 102. The length of the long slot 102 may extend in the left-right direction, and the two positioning rotating blocks 20 may be symmetrically arranged in the long slot 102, one on the left and one on the right. Two holes may be arranged on the fixture body 10, and the two combination pins 30 are respectively inserted into the two holes and pass through the mounting holes of the two positioning rotating blocks 20, so as to realize the rotatable arrangement of the positioning rotating blocks 20.

[0038] In some optional embodiments, the fixture body 10 further includes a limiting boss 104 disposed at the rear end of the top surface 101. The limiting boss 104 is higher than the top surface 101 and is used to block and limit the speaker assembly (specifically, the basin frame). The limiting boss 104 can be used to limit the speaker assembly in the front and rear directions.

[0039] In some optional embodiments, the limiting boss 104 has two limiting surfaces on one side relative to the through hole 103, and the two limiting surfaces form a V-shaped groove 105. The speaker frame can be inserted into the V-shaped groove 105 and contact the two limiting surfaces. The V-shaped groove 105 of the limiting boss 104 can be used to limit the speaker assembly in the left and right directions.

[0040] In some optional embodiments, such as Figure 5 and Figure 6 The height of the front end of the jig body 10 is greater than the height of the rear end thereof. When the jig body 10 is laid flat, its top surface 101 is an inclined surface with a higher front end and a lower rear end. Thus, after the speaker assembly is placed on the top surface 101, the speaker assembly can slide toward the rear end under the action of gravity, and approach and abut against the limiting boss 104, thereby automatically completing the limitation in the front and rear directions; at the same time, the limiting boss 104 has a V-shaped groove 105, and in the process of the speaker assembly sliding toward the rear end, the V-shaped groove 105 corrects the left and right position, thereby achieving the limitation in the left and right directions.

[0041] In some optional embodiments, reference Figure 2 The midpoint of the line connecting the centers of the two positioning rotating blocks 20 (or the midpoint of the long slot 102 in the length direction, or the midpoint of the line connecting the two combination pins 30), the center point of the through hole 103 and the vertex of the V-shaped groove 105 are located on the same straight line (a straight line in the front-to-back direction), and the straight line is perpendicular to the extension direction of the length of the long slot 102.

[0042] In some optional embodiments, reference Figure 4 The positioning rotating block 20 has a mounting hole sleeved on the combination pin 30, and the mounting hole is close to the inner side edge of the positioning rotating block 20 and away from the outer side edge. Optionally, the inner side edge is a straight line and the outer side edge is an arc shape.

[0043] In some optional embodiments, reference Figure 4 The positioning pressure column 201 is vertically arranged on the upper surface of the positioning rotating block 20, and the curvature adjustment block 202 is inclined toward the outside on the upper surface of the positioning rotating block 20, and the inclination angle is, for example, between 45 degrees and 90 degrees (preferably between 60 degrees and 75 degrees). An angle can be formed between the outer side surface of the curvature adjustment block 202 and the upper surface of the positioning rotating block 20, and the angle is an acute angle between 45 degrees and 90 degrees (preferably between 60 degrees and 75 degrees). The angle can be used to clamp the brocade thread and play a fixing role to prevent the brocade thread from rebounding, shrinking, and moving after the thread is adjusted.

[0044] In some optional embodiments, the distance from the vertex of the arc adjustment block 202 to the upper surface of the positioning rotation block 20 is greater than the distance from the vertex of the positioning pressure column 201 to the upper surface of the positioning rotation block 20 .

[0045] In some optional embodiments, when the positioning rotating block 20 is rotated outward to a preset angle, the upper surface of the positioning rotating block 20 is flush with the top surface 101 of the fixture body 10 , or is parallel but the distance is within a limited range.

[0046] As mentioned above, the line adjustment tooling proposed in the embodiment of the present application is mainly composed of a fixture body 10, a positioning rotating block 20 (with a positioning pressure column 201 and an arc adjustment block 202) and a combination pin 30, and the functions of each component are as follows:

[0047] The fixture body 10: plays the role of overall support and positioning of the product (speaker assembly). The outer diameter of the speaker assembly basin frame determines the limit size of the fixture body 10, and its limit can meet the function of rapid positioning of the product;

[0048] The positioning rotating block 20, whose positioning pressurizing column 201 is used as the object for positioning and pressurizing the basin frame when the speaker assembly is placed, makes the pressurizing column move downward after the basin frame is pressurized, drives the positioning rotating block 20 to rotate, and makes the curvature adjusting block 202 move outward, that is, the two curvature adjusting blocks 202 are adjusted in both directions respectively, and the curvature adjusting blocks 202 play the role of adjusting the curvature of the brocade silk thread, ensuring that the curvature of the brocade silk thread is adjusted in place, meets the curvature requirements of the brocade silk thread, and ensures the consistency of the curvature;

[0049] Combination pin 30: used for connecting and fixing the fixture body 10 and the positioning rotating block 20, serving as a central pivot for connecting the two and as a pivot for the positioning rotating block 20 to rotate.

[0050] The working principle of the line adjustment tool proposed in the embodiment of the present application is as follows:

[0051] The speaker assembly is placed on the fixture body 10, and the speaker assembly is positioned and fixed by the top surface 101 and the limiting boss 104. When the speaker assembly is placed and pressed down by gravity, the basin frame of the speaker assembly presses the positioning pressure column 201 downward, and the synchronous curvature adjustment block 202 moves to both sides, and the curvature of the brocade silk thread is adjusted in both directions in a "butterfly-shaped" process.

[0052] refer to Figure 7 , shows a schematic diagram of the silk thread 41 before and after the curvature adjustment. Figure 7 As shown in (a), one end of the silk wire 41 is connected to the voice coil 42, and the other end passes through the opening (not welded) on the terminal board 43. A certain position in the middle of the silk wire 41 is stuck on the outer side of the arc adjustment block 202. Before adjustment, the silk wire 41 is roughly straight. Figure 7 As shown in (b), during the adjustment process, the arc adjustment block 202 moves outward, causing the middle of the silk thread 41 to shift outward, so that the silk thread 41 forms an arc; and optionally, the silk thread 41 is stuck in the angle between the outer side of the arc adjustment block 202 and the upper surface of the positioning rotating block 20, and is fixed by the angle. Figure 7 As shown in (c), after the wire adjustment is completed, the brocade wire 41 and the terminal board 43 can be welded together through a welding process, and the excess brocade wire 41 can be cut short. At this time, both ends of the brocade wire 41 are fixed, and the curvature formed by the brocade wire 41 is also fixed.

[0053] The line adjustment tooling proposed in the embodiment of the present application uses gravity to press and adjust the curvature of the silk thread to ensure the consistency of the curvature of the silk thread. The mechanism uses a fixture body 10, a positioning turn block 20 and a combination pin 30, wherein the positioning turn block 20 also includes a positioning pressure column 201 and a curvature adjustment block 202. After the speaker assembly is placed on the fixture body 10, the continuous action meets the line adjustment requirements of the speaker silk thread, improves the consistency of the line adjustment, and solves the efficiency problem of silk thread adjustment in the industry. Among them, the inconsistency of the left and right gravity of the positioning turn block 20 is used. In the natural state, the positioning turn block 20 is tightened inward, and the positioning pressure column 201 on the outside thereof is tilted upward. When the speaker assembly is pressed down, the positioning turn block 20 is tightened outward, and the curvature adjustment block 202 on the inside thereof is tilted upward, thereby realizing the curvature adjustment of the silk thread. This application breaks through the difficulties of the silk thread in the speaker industry that the curvature of the silk thread is inconsistent and the adjustment efficiency is slow after the line adjustment is completed. The line adjustment tooling of the present application can be applied to the line adjustment process of speakers of various sizes, and has strong applicability and consistent stability.

[0054] During the production process, the present application breaks through the limitations of traditional wire adjustment tooling and fixtures that use rods and sheets for insertion, meets the requirements of the Jinsi wire curvature process, and utilizes the gravity effect to save unnecessary wire adjustment movements, thereby achieving both the requirements of the process and the efficiency requirements of quickly adjusting the curvature of the Jinsi wire. At the same time, it meets the function of fixing the Jinsi wire in its effective position in the speaker industry, improves the consistency of wire adjustment, and can effectively prevent the problem of Jinsi wire hitting. This helps to solve the problem of wire hitting in the industry and greatly improves the yield and stability of the product.
