Abstract
Description
Technical Field
[0001] This application belongs to the field of loudspeaker tooling and fixture technology, and relates to tooling and fixtures for loudspeaker wiring, specifically to a general-purpose pneumatic arc tooling for internal and external magnet loudspeakers. Background Technology
[0002] A loudspeaker (or horn) is a transducer that converts electrical signals into sound signals. Loudspeakers produce sound by causing their cones to vibrate and resonate with the surrounding air through electromagnetic, piezoelectric, or electrostatic effects. Loudspeakers can be installed in home televisions, multimedia home audio systems, outdoor audio systems, automobiles, karaoke venues, public address systems, computers, etc., as sound-generating units.
[0003] Most loudspeakers use leads to conduct signals, typically nylon wire. During loudspeaker operation, the vibration of the voice coil causes the nylon wire to vibrate. To avoid issues such as wire kinking (the nylon wire hitting the cone), tooling fixtures are designed during the loudspeaker assembly process to adjust the nylon wire, i.e., to adjust the curvature of the nylon wire to allow for a certain length.
[0004] Currently, the wiring positioning fixtures used in the industry typically employ inserts or plates. The wiring process involves inserting the fixture into the speaker, manually pulling the wire to form an arc, and then soldering the wire to the speaker's terminal block. Because the fixture design takes into account interference between the fixture and the speaker frame, there is usually a large clearance between the fixture and the speaker frame to allow for wiring adjustment. During manual placement and wire pulling, the fixture is prone to misalignment or displacement, leading to incomplete wiring or excessive arc, resulting in poor wiring and making the speaker unable to meet sound quality requirements. Furthermore, this wiring process is primarily manual, resulting in poor consistency and low efficiency. Utility Model Content
[0005] The main technical problem addressed by this application is to provide a universal pneumatic arc tooling for internal and external magnetic loudspeakers, used for adjusting the arc of the loudspeaker's nylon wire, improving the consistency and efficiency of wire adjustment, so as to meet the sound quality performance requirements of the loudspeaker.

[0010] The pneumatic mechanism has a moving part that extends into the body of the fixture and is located below the wire adjustment slot, and the moving part is movable relative to the wire adjustment slot.
[0011] The pair of adjusting posts are located inside the adjusting groove and fixed to the moving part of the pneumatic mechanism. They can adjust their relative positions as the moving part moves to adjust the curvature of the brocade thread.
[0012] In some alternative embodiments, the adjusting groove, the clearance hole, and the adjusting block are arranged sequentially from the front end to the rear end on the upper surface.
[0013] In some alternative embodiments, the center line connecting the adjustment groove, the clearance hole, and the adjustment block is perpendicular to the line connecting the pair of adjustment posts.
[0014] In some alternative embodiments, the pneumatic mechanism includes two cylinders, left and right, and the pair of adjusting pins are respectively connected to the moving parts of the two cylinders.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.
[0029] The terms "first," "second," "third," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.
[0030] The following detailed descriptions will be provided through specific embodiments.
[0031] refer to Figure 1 and Figure 2 This application provides a universal pneumatic curvature fixture for internal and external magnetic loudspeakers, used for adjusting the curvature of the nylon wire in the loudspeaker assembly. Figures 1 to 2 As shown, the tooling of this application includes: a fixture body 10, a pair of adjusting posts 20, a pair of adjusting plates 30, an adjusting block 40, and a pneumatic mechanism 50.
[0032] The fixture body 10 has an upper surface 11 and a wiring groove 12 and a clearance hole 13 formed on the upper surface 11. The upper surface 11 is used to place the speaker assembly, and the clearance hole 13 is used to avoid the voice coil of the speaker assembly. Optionally, the clearance hole 13 is located in the middle of the upper surface 11, and the wiring groove 12 is located at the front end of the upper surface 11 and extends laterally.
[0033] A pair of adjustment plates 20 are adjustablely positioned on the upper surface 11 of the fixture body 10; optionally, the two adjustment plates 20 are arranged on the left and right sides to limit the speaker assembly from the left and right directions.
[0034] Adjustment block 30 is adjustablely disposed on the upper surface 11 of fixture body 10; optionally, adjustment block 30 is located at the rear end of upper surface 11 to limit speaker assembly from the front and rear directions.
[0035] The pneumatic mechanism 40 has a moving part that extends into the body of the fixture 10 and is located below the wire alignment slot 12. The moving part is movable relative to the wire alignment slot 12.
[0036] A pair of adjusting posts 50 are located inside the adjusting groove 12 and fixed on the moving part of the pneumatic mechanism 40. They can adjust their relative positions as the moving part moves. That is, the two adjusting posts 50 can move away from or closer to each other under the drive of the pneumatic mechanism 40, thereby adjusting the curvature of the brocade thread.
[0037] Here, a loudspeaker assembly can refer to a loudspeaker that is not yet fully assembled and does not have a diaphragm. The loudspeaker assembly may include a loudspeaker frame, voice coil, spider (centering support), nylon wire, etc., but may not include a diaphragm (i.e., cone or vibrator).
[0038] In some alternative embodiments, the clearance hole 13 is an elliptical hole to better clear the voice coil. The front-to-back length of the elliptical hole can be greater than its left-to-right width, thereby allowing the speaker assembly to be positioned back-to-back and then locked after being placed on the fixture body 10, ensuring a more precise position of the speaker assembly relative to the pair of tuning posts 50.
[0039] In some alternative embodiments, the adjusting groove 12, the clearance hole 13, and the adjusting block 40 are arranged sequentially from the front end to the rear end on the upper surface 11, and their centers may be located on the same straight line.
[0040] In some alternative embodiments, the center line connecting the adjusting groove 12, the clearance hole 13, and the adjusting block 40 is perpendicular to the line connecting the pair of adjusting posts 50.
[0041] In some alternative embodiments, the upper surface 11 of the fixture body 10 is an inclined surface, and the rear end where the front and rear adjustment blocks 30 are located is lower than the front end where the adjustment groove 12 is located. In this way, when the speaker assembly is placed on the upper surface 11 of the fixture body 10, it will slide towards the rear end and be stopped by the front and rear adjustment blocks 30, thereby achieving a limit in the front-rear direction.
[0042] In some alternative embodiments, the pneumatic mechanism 40 includes two cylinders, left and right, and a pair of adjusting posts 50 connected to the moving parts of the two cylinders, such as the piston rods of the cylinders. When the piston rods of the two cylinders are in an extended or retracted state, they cause the relative distance between the two adjusting posts 50 to change.
[0043] In some alternative implementations, the height of a pair of adjusting posts 50 can be adjusted vertically. Specifically, the adjusting posts 50 can be connected to the piston rod of the cylinder via a threaded connection, and their height can be adjusted by rotation.
[0044] In some alternative embodiments, the fixture body 10 has a cylinder mounting hole for accommodating a cylinder, and the wire adjustment groove 12 communicates with the cylinder mounting hole.
[0045] In some alternative embodiments, it also includes two mounting brackets 60 for fixing the two cylinders to the fixture body 10 respectively.
[0046] In some alternative embodiments, the method further includes: a pair of adjustment plates 20 with V-shaped opposite sides for clamping the speaker assembly. The V-shaped surfaces are suitable for speaker assemblies of different diameters, all of which can achieve good positioning.
[0047] In some alternative embodiments, a pair of pressure plates 70 are also included to help fix a pair of adjustment plates 20 to the fixture body 10, ensuring that the adjustment plates 20 do not loosen, and can also be used to assist in moving the adjustment plates 20.
[0048] In some alternative implementations, a foot switch for controlling the pneumatic mechanism 40 is also included. This allows the operator to control the pneumatic switch using only their foot, freeing up both hands to perform other operations, reducing wasted movement, and further improving work efficiency.
[0049] The working principle of this embodiment is as follows: The speaker assembly is placed on the upper surface 11 of the fixture body 10. The speaker assembly is limited by a pair of adjusting plates 20 and adjusting blocks 30. The operator steps on the foot switch, and compressed air enters the pneumatic mechanism 40. The pneumatic mechanism 40 drives a pair of adjusting posts 50 to move and adjust the curvature of the wire. Then, soldering can be performed to solder the wire to the terminal block of the speaker frame. After the solder solidifies, the operator releases the foot switch, and the pair of adjusting posts 50 reset. At this time, the adjusted speaker assembly can be taken out and put into the next process.
[0050] The tooling in this embodiment locks the distance between a pair of adjusting posts 50 with a cylinder, and the distance between the two adjusting posts 50 can be adjusted to accommodate different radii of the distance. Furthermore, the adjusting posts 50 are fixed to the cylinder by a threaded locking method, and their height can be adjusted vertically to accommodate speakers of different heights. Additionally, the adjusting posts 50 can be driven by the cylinder and controlled by a foot pedal switch. Furthermore, a pair of position-adjustable adjusting plates 20 and adjusting blocks 30 limit the speaker assembly, satisfying various product appearance positioning requirements. Moreover, an elliptical clearance hole is provided in the middle of the fixture body 10 to accommodate various voice coils of different speaker assemblies.
[0051] This application embodiment also provides a loudspeaker wiring method for a universal internal and external magnet loudspeaker pneumatic arc fixture as described above. The method includes the following steps:
[0052] S1. Place the speaker assembly on the upper surface of the fixture body, so that the voice coil of the speaker assembly falls into the clearance hole, and so that the two nylon wires of the speaker assembly are close to a pair of tuning posts respectively.
[0053] S2. Control the operation of the pneumatic mechanism to move a pair of adjusting columns and complete the curvature adjustment of the two brocade threads;
[0054] S3. After the brocade wire is soldered to the terminal block of the speaker assembly, control the pneumatic mechanism to restore a pair of tuning pins to their initial positions.
[0055] The present application provides a general-purpose pneumatic arc fixture for internal and external magnetic loudspeakers, and also proposes a corresponding method. By employing the above features, the technical effects achieved by this application include, but are not limited to:
[0056] 1. Reduced manual work, higher degree of automation, and higher line adjustment efficiency.
[0057] 2. A pair of adjustment columns are precisely controlled by a pneumatic mechanism, which can improve the consistency of the adjustment arc.
[0058] 3. The distance and height of a pair of tuning pins are adjustable. The positions of a pair of adjusting plates 20 and adjusting blocks 30 used for limiting are adjustable. The voice coil clearance hole 13 adopts an elliptical hole, thus making it suitable for a variety of different products and expanding its application range.
[0059] 4. The speaker assembly can be tuned before the diaphragm is installed (i.e., the speaker assembly mentioned above may not include the diaphragm / resonator / cone). Therefore, the tuning area can be visually inspected during the tuning process to ensure higher tuning quality.
[0060] In summary, the tooling of this application is more integrated, the consistency of lead wire curvature adjustment is better, the efficiency is higher than that of traditional processes, the product has a wider range of applications, and the quality is more stable.
[0061] The technical solution of this application has been described in detail above through specific embodiments. In the above embodiments, the descriptions of each embodiment have their own emphasis, and for parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.
[0062] It should be understood that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; however, these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and protection scope of the technical solutions of the embodiments of this application.
