Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of loudspeaker tooling and fixtures, and relates to tooling and fixtures for loudspeaker line adjustment, and specifically to a universal pneumatic arc tooling and method for internal and external magnetic loudspeakers. 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 thread as the lead. When the speaker is working, the vibration of the voice coil will drive the silk thread to vibrate. In order to avoid problems such as wire hitting (the silk thread hits the paper cone), it is necessary to design a tooling fixture to adjust the silk thread during the speaker assembly process, that is, adjust the curvature of the silk thread to reserve a certain length.
[0004] The wire adjustment and positioning tooling jigs currently used in the industry are usually mainly in the form of inserting rods and inserting pieces. The wire adjustment process includes: after inserting the wire adjustment jig into the speaker, manually pulling the wire to form an arc, and then soldering the wire to the terminal board of the speaker. Because the interference between the jig and the speaker basin frame is taken into consideration when designing the jig, there is usually a large gap between the wire adjustment jig and the speaker basin frame before it can be placed in the basin frame for wire adjustment. During the manual placement and wire pulling process, the jig is prone to skew and displacement, which will lead to problems such as inadequate wire adjustment or excessive wire adjustment arc, which will lead to poor wiring and make it difficult for the speaker to meet the sound quality performance requirements. Moreover, the above-mentioned wire adjustment process mainly uses manual work, with poor consistency and low efficiency. Summary of the invention
[0005] The main technical problem solved by the present application is to provide a universal internal and external magnetic loudspeaker pneumatic curvature tooling and method for adjusting the curvature of the loudspeaker's silk thread, improving the consistency of the line adjustment, and improving the efficiency of the line adjustment to meet the sound quality performance requirements of the loudspeaker.

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.
[0034] The following describes the embodiments in detail.
[0035] refer to Figure 1 and Figure 2 The present application provides a universal internal and external magnetic loudspeaker pneumatic curvature tooling, which is used to adjust the curvature of the silk thread in the loudspeaker assembly. Figure 1 to Figure 2 As shown, the tooling of the present application includes: a fixture body 10, a pair of adjustment posts 20, a pair of adjustment plates 30, an adjustment block 40 and a pneumatic mechanism 50.
[0036] The fixture body 10 has an upper surface 11 and a wire adjustment groove 12 and an air avoidance hole 13 opened on the upper surface 11. The upper surface 11 is used to place the speaker assembly, and the air avoidance hole 13 is used to avoid the voice coil of the speaker assembly; optionally, the air avoidance hole 13 is located in the middle of the upper surface 11, and the wire adjustment groove 12 is located at the front end of the upper surface 11 and extends laterally;
[0037] A pair of adjustment plates 20, which are adjustable in position and arranged on the upper surface 11 of the fixture body 10; optionally, the two adjustment plates 20 are arranged one on the left and one on the right, and are used to limit the speaker assembly from the left and right directions;
[0038] An adjustment block 30 is arranged on the upper surface 11 of the fixture body 10 in an adjustable position; optionally, the adjustment block 30 is located at the rear end of the upper surface 11, and is used to limit the speaker assembly from the front and rear directions;
[0039] The pneumatic mechanism 40 has a moving part extending into the interior of the fixture body 10 and located below the wire adjustment groove 12, and the moving part can move relative to the wire adjustment groove 12;
[0040] A pair of line-adjusting posts 50 are located in the line-adjusting groove 12 and fixed on the moving part of the pneumatic mechanism 40. The relative positions can be adjusted as the moving part moves. That is, the two line-adjusting posts 50 can move away from or closer to each other under the drive of the pneumatic mechanism 40, thereby being used to adjust the curvature of the silk thread.
[0041] Here, the speaker assembly may refer to a speaker that has not been fully assembled and is not equipped with a drum paper. The speaker assembly may include a speaker basin frame, a voice coil, a spring (centering support), a silk thread, etc., but may not include a drum paper (i.e., a sound basin or a diaphragm).
[0042] In some optional embodiments, the air-avoiding hole 13 is an elliptical hole to better avoid the voice coil. The front-to-back length of the elliptical hole can be greater than the left-to-right width, so that the speaker assembly can be placed on the fixture body 10 and then adjusted to the front-to-back position before limiting, ensuring that the position of the speaker assembly relative to the pair of adjustment posts 50 is more accurate.
[0043] In some optional embodiments, the line adjustment groove 12, the air avoidance hole 13 and the adjustment block 40 are arranged in sequence from the front end to the rear end on the upper surface 11, and the centers may be located on the same straight line.
[0044] In some optional embodiments, a line connecting the centers of the line-adjusting groove 12 , the air-avoiding hole 13 and the adjusting block 40 is perpendicular to a line connecting a pair of line-adjusting poles 50 .
[0045] In some optional embodiments, the upper surface 11 of the jig body 10 is an inclined surface, and the rear end where the front and rear adjustment block 30 is located is lower than the front end where the adjustment slot 12 is located. In this way, when the speaker assembly is placed on the upper surface 11 of the jig body 10, it will slide to the rear end and be stopped by the front and rear adjustment block 30, thereby achieving position limitation in the front and rear direction.
[0046] In some optional embodiments, the pneumatic mechanism 40 includes two left and right cylinders, and a pair of line adjustment posts 50 are respectively connected to the moving parts of the two cylinders, and the moving parts mentioned here are, for example, piston rods of the cylinders. The piston rods of the two cylinders are opposite to each other, and when the two are in an extended state or a retracted state, the relative distance between the two line adjustment posts 50 is driven to change.
[0047] In some optional embodiments, a pair of line-adjusting posts 50 can be adjusted in height up and down. Specifically, the line-adjusting posts 50 can be connected to the piston rod of the cylinder by threaded connection, and can be adjusted in height by rotation.
[0048] In some optional embodiments, the fixture body 10 has a cylinder mounting hole for accommodating the cylinder, and the line adjustment groove 12 is connected to the cylinder mounting hole.
[0049] In some optional embodiments, the present invention further includes: two mounting brackets 60 for fixing the two cylinders to the fixture body 10 respectively.
[0050] In some optional embodiments, the pair of adjustment plates 20 may have opposite sides that are V-shaped for clamping the speaker assembly. The V-shaped surface may be suitable for speaker assemblies of different diameters and may provide good positioning.
[0051] In some optional embodiments, a pair of pressing plates 70 are further included to assist in fixing the pair of adjustment plates 20 on the fixture body 10 to ensure that the adjustment plates 20 are not loose, and can further be used to assist in moving the adjustment plates 20.
[0052] In some optional embodiments, it further includes: a foot switch for controlling the pneumatic mechanism 40. In this way, the operator only needs to use his feet to control the pneumatic switch, freeing both hands to perform other operations, reducing the waste of actions, and further improving the working efficiency.
[0053] The working principle of the embodiment of the present application is as follows: the speaker assembly is placed on the upper surface 11 of the fixture body 10, and the speaker assembly is limited by a pair of adjustment plates 20 and an adjustment block 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 columns 50 to move the position, and the curvature of the silk wire is adjusted. Then soldering can be performed to weld the silk wire to the terminal board of the speaker basin frame. After the tin liquid solidifies, the operator releases the foot switch, and the pair of adjusting columns 50 are reset. At this time, the adjusted speaker assembly can be taken out and put into the next process.
[0054] The tooling of the embodiment of the present application locks the distance between a pair of line-adjusting posts 50 through a cylinder, and can adjust the distance between the two line-adjusting posts 50, which can be suitable for adjusting the arc at different distances; in addition, the line-adjusting posts 50 are fixed to the cylinder by threaded locking, and the height can be adjusted up and down, which is suitable for speakers of different heights; in addition, the line-adjusting posts 50 can be driven by the cylinder and can be controlled by stepping on a foot switch; in addition, a pair of adjustable adjustment plates 20 and adjustment blocks 30 are used to limit the speaker assembly, which can meet the appearance positioning of various products; in addition, an elliptical air-avoiding hole is set in the middle of the fixture body 10, which can accommodate various different voice coils of various speaker assemblies.
[0055] The present application also provides a speaker line adjustment method for the universal internal and external magnetic speaker pneumatic arc tooling as described above, the method comprising the following steps:
[0056] 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 air avoidance hole and the two silk threads of the speaker assembly are close to a pair of line adjustment posts respectively;
[0057] S2, control the pneumatic mechanism to move a pair of wire adjustment posts to complete the curvature adjustment of the two silk threads;
[0058] S3. After the welding of the Jinsi wire and the terminal board of the speaker assembly is completed, the pneumatic mechanism is controlled to restore a pair of wire adjustment posts to their initial positions.
[0059] As mentioned above, the embodiment of the present application proposes a universal internal and external magnetic loudspeaker pneumatic arc tooling, and also proposes a corresponding method. By adopting the above features, the technical effects achieved by the present application include but are not limited to:
[0060] 1. Reduced manual work, higher degree of automation and higher line adjustment efficiency.
[0061] 2. A pair of line adjustment columns are precisely controlled by a pneumatic mechanism to improve the consistency of the line adjustment arc.
[0062] 3. The distance and height of a pair of adjusting posts are adjustable, the positions of a pair of adjusting plates 20 and adjusting blocks 30 used for limiting are adjustable, and the air avoidance hole 13 of the voice coil is an elliptical hole, so that it can be applied to a variety of different products and has a wider range of applications.
[0063] 4. The speaker assembly can be adjusted before the drum paper is installed (that is, the speaker assembly described above may not include the drum paper / diaphragm / cone). Therefore, the adjustment area can be visually inspected during the adjustment process to ensure higher adjustment quality.
[0064] In summary, the tooling of the present application has stronger integration, better consistency in adjusting the lead curvature, higher efficiency than traditional processes, a wider range of product applications, and more stable quality.
