Description

Technical Field

[0001] This utility model relates to the field of loudspeakers, and in particular to a loudspeaker structure that is easy to install. Background Technology

[0002] Existing loudspeakers generally include a magnetic circuit assembly and a driving assembly to achieve a predetermined vibration and sound production. The magnetic circuit assembly typically includes a magnetic guide assembly and a magnet assembly. The magnetic guide assembly constrains and guides the magnetic field of the magnet assembly, thereby forming a predetermined magnetic field direction.

[0003] Existing magnetic sheets and magnet assemblies are generally glued together for assembly. With the miniaturization of loudspeakers (e.g., wireless headphones), magnetic sheets are becoming larger, thus taking up a significant amount of thickness in actual assembly. Furthermore, the increase in the number of individual magnetic sheets during the production process (not limited to one or more) results in low production efficiency and long process time (and with the development of automated assembly, the connection of this structure is becoming poor). At the same time, the coaxiality of the assembled magnetic sheets also affects the sound quality of the loudspeaker. Utility Model Content

[0004] The main purpose of this invention is to propose a speaker structure that is easy to install, aiming to improve the existing matching structure of the magnetic sheet and the bracket. It can reduce assembly steps while ensuring the coaxiality of the outer magnetic sheet, thereby improving the sound quality of the speaker.

[0005] To achieve the above objectives, this utility model proposes a speaker structure that is easy to install, comprising:

[0006] The support frame is made of plastic material;

[0007] A magnetic conductive sheet, with a first support arm extending outward from the magnetic conductive sheet, and a bracket integrally injection molded with the magnetic conductive sheet to form a positioning frame.

[0008] Once formed into a positioning frame, the first support arm extends out of the wall of the positioning frame.

[0009] In actual processing, a simple design enabled the automated manufacturing of the positioning frame. The magnetic sheet is placed inside an injection mold, and then the frame is injection molded to enclose the magnetic sheet, thus eliminating assembly steps.

[0010] At the same time, the structural stability and overall thickness of the support structure are reduced, which in turn reduces the thickness of the speaker, thereby miniaturizing the speaker and improving assembly efficiency.

[0011] The extended first support arm is used to realize the integrated movement or transmission of the material strip, thereby enabling rapid injection molding. It can realize automated magnetic sheet feeding, injection molding and unloading, effectively improving production efficiency. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0024] like Figures 1 to 5 As shown, a speaker structure that is easy to install includes:

[0025] Support 1, wherein the support 1 is made of plastic material;

[0026] Magnetic sheet 2, with a first support arm 20 extending outward from it, and bracket 1 integrally injection molded with magnetic sheet 2 to form a positioning frame.

[0027] Once formed into a positioning frame, the first support arm 20 extends out of the wall of the positioning frame.

[0028] In actual processing, a simple design enabled automated machining of the positioning frame. The magnetic sheet 2 is placed inside the injection mold, and then the bracket 1 is injection molded to enclose the magnetic sheet 2, thus eliminating assembly steps.

[0029] At the same time, the structural stability and overall thickness of the support 1 are reduced, thereby reducing the thickness of the speaker and improving assembly efficiency while miniaturizing the speaker.

[0030] The extended first support arm 20 is used to realize the integrated movement or transmission of the material strip, thereby enabling rapid injection molding. It can realize the automated feeding, injection molding and unloading of the magnetic sheet 2, effectively improving production efficiency.

[0031] The bracket 1 and the magnetic sheet 2 partially or completely cover each other. For example, the outer peripheral wall of the outer magnetic sheet is embedded in the bracket 1, and the inner peripheral wall of the outer magnetic sheet is suspended in the bracket 1 (of course, the bracket 1 can also be configured to cover the bottom or top wall of the inner peripheral wall of the outer magnetic sheet, so as to meet the production needs of different speakers).

[0032] After the bracket 1 is integrally formed with the conductive terminal 3 and the magnetic sheet, the first arm and the second arm are cut off, thereby separating the bracket 1 from the first strip and the second strip, thus realizing the installation of the bracket 1.

[0033] Specifically, it also includes a first material strip 21, which is provided with first support arms 20 spaced apart. The end of the first support arm 20 away from the first material strip 21 is provided with the magnetic sheet, thereby realizing automated transmission and making the processing of the magnetic sheet faster.

[0034] In this embodiment of the present invention, conductive terminals 3 are provided on both sides of the first support arm 20. The conductive terminals 3 are integrally injection molded with the bracket 1, wherein the electronic terminals are used for the electrical connection of the voice coil.

[0035] Specifically, the conductive terminal 3 is provided with a second support arm 30 extending out of the bracket 1, wherein the second support arm 30 is used to facilitate placement during injection molding.

[0036] In this embodiment of the utility model, the second support arm 30 is disposed on the second material strip 31. The second material strip 31 and the first material strip 21 are stacked in the Z-axis direction, thereby realizing the integral injection molding of the two, thus realizing the molding of two different materials. The structure is simple and stable, effectively improving production efficiency. In actual injection molding, the first material strip 21 and the second material strip 31 can be fixed to each other before being placed in the injection mold. Of course, in automated production, the cooperation method of the two can be set according to actual needs. In addition, the Z-axis direction misalignment setting can realize the misaligned molding of the magnetic sheet and the conductive terminal 3.

[0037] Specifically, the magnetic sheet is an inner magnetic sheet or an outer magnetic sheet. In actual design, an outer magnetic sheet is preferred. Of course, an inner magnetic sheet can also be integrally injection molded. In the actual design, the bracket 1 will have a bottom wall and a staggered structure needs to be set.

[0038] In this embodiment of the invention, the magnetic conductive sheet is ring-shaped or sheet-shaped, and when it is an inner magnetic ring, most of the structures are circular, rectangular, or elliptical sheets.

[0039] Specifically, the magnetic conductive sheet is a circular magnetic conductive sheet. The circular magnetic conductive sheet has notches 22 extending towards the axis on both sides of the first support arm 20. The cross-section of the bracket 1 is circular, which allows the bracket 1 to achieve a smaller width to integrally injection mold the outer magnetic conductive sheet and the conductive terminal 3, thereby reducing the assembly process and making the structure more compact, avoiding the need for a larger width for the electrical end part to be installed.

[0040] In this embodiment of the utility model, the conductive terminal 3 is made of a non-magnetic material. The design difficulty lies in the fact that the two are not the same metal, so the first strip and the second strip need to be stacked and injection molded, which affects the stability of the molding.

[0041] Specifically, the conductive terminal 3 includes an inner terminal 301 and an outer terminal 302 that bends and extends from the outer end of the inner terminal 301. The second support arm 30 extends outward from the direction of the inner terminal 301, thereby realizing the misaligned design while also achieving integral injection molding.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
