[0002] The present disclosure relates to a loudspeaker and an assembling method thereof, and in particular to a thin loudspeaker and an assembling method thereof. Background Art

[0003] A loudspeaker is an electroacoustic conversion element that can be installed in a car as part of an in-car multimedia system or as part of a pedestrian warning system for a new energy vehicle. Car speakers often have positioning supports to prevent the voice coil and diaphragm from moving away from the axis of motion, such as horizontal shaking, to reduce the possibility of abnormal noise. In an existing loudspeaker, the positioning support is set below the diaphragm. The positioning support usually has a voice coil hole in the middle. The voice coil skeleton passes through the voice coil hole so that the positioning support is mounted on the voice coil skeleton. The outer edge of the positioning support is bonded to the basin frame. The setting of the positioning support requires a certain amount of space in the height direction, making the overall height of the loudspeaker relatively large and placing high demands on the installation space on the vehicle. In addition, the voice coil needs to pass through the positioning support and be connected to each other, making the assembly process of the loudspeaker relatively complicated. Summary of the Invention

[0045] The preferred embodiments of the present disclosure are described in detail below with reference to the accompanying drawings to make the advantages and features of the present disclosure more easily understood by those skilled in the art. It should be noted that the descriptions of these embodiments are intended to facilitate understanding of the present disclosure and do not constitute a limitation of the present disclosure. In addition, the technical features involved in the various embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.

[0046] In this disclosure, the terms "inside" and "outside" are defined relative to the centerline of the voice coil, with the direction closer to the centerline considered inside and the direction farther away from it considered outside. The directional terms "upper," "lower," and "horizontal" are intended to facilitate understanding of the structure of a speaker system and are not intended to define the position of the speaker after installation. For example, a speaker can be mounted on a horizontal, inclined, or vertical surface within a vehicle.

[0047] Figures 1 to 4 illustrate a speaker according to this embodiment, specifically a car speaker, which can be used, for example, as a mid-bass speaker for an in-vehicle multimedia system. This embodiment also provides a car audio system, including a mid-range speaker or a woofer, wherein the mid-range speaker or woofer employs the speaker shown in Figures 1 to 4 .

[0048] As shown in Figures 1 to 4 , the loudspeaker comprises a frame 1, a diaphragm 2 mounted on the frame 1, a voice coil 3 connected to the diaphragm 2, a magnetic driver 4 for driving the voice coil 3 to vibrate along its centerline O, and a positioning arm 5. As shown in Figure 2 , the voice coil 3 has a centerline O. This reference is used herein to describe the positions of the various components. The centerline O of the voice coil 3 is also the axis of motion of the loudspeaker, specifically, its diaphragm 2.

[0049] The frame 1 is a single, integrally molded component, for example, from plastic injection molding. The frame 1 can be made of, for example, polypropylene (PP). The upper end of the frame 1 is open, while the bottom is recessed to form a cavity. The upper end of the frame 1 has a horizontal upper surface for mounting the positioning support 5 and diaphragm 2.

[0050] The diaphragm 2 primarily consists of two parts: the diaphragm body 21 and the surround 22. These two components can be integrated or fixed together using glue or other methods. The center of the surround 22 is arched upward, and the outer edge of the surround 22 extends horizontally outward to form a horizontal flange 23, which connects to the frame 1. A voice coil mounting hole is defined in the center of the diaphragm body 21. The diaphragm body 21 gradually slopes upward from the voice coil mounting hole to the surround 22 (i.e., from the inside out), resulting in an overall truncated cone or pyramidal shape. Therefore, the voice coil mounting hole is located at the bottom of the diaphragm body 21, while the top of the diaphragm body 21 is connected to the surround 22. The diaphragm body 21 can be made of paper, fabric, or other materials, while the surround 22 can be made of rubber. The diaphragm body 21 has a front and a back surface. The front surface faces outward to radiate sound, and is therefore also called the sound radiating surface. The back surface faces the inside of the speaker and is positioned opposite the magnetic driver 4.

[0051] The voice coil 3 is generally hollow and cylindrical. Its upper portion passes through the voice coil mounting hole of the diaphragm body 21, and its lower portion is movably inserted along the centerline O into the magnetic gap of the magnetic driver 4. The voice coil 3 specifically comprises a cylindrical frame and a coil wound around the lower portion of the frame. The coil can receive a current signal and vibrates up and down under the magnetic field of the magnetic driver 4, thereby driving the diaphragm 2 to vibrate and produce sound.

[0052] The magnetic driver 4 specifically comprises a U-shaped iron 41, a magnet 42, and a front plate 43. The center of the U-shaped iron 41 is recessed downward, with the magnet 42 and front plate 43 stacked on top of the bottom. The U-shaped iron 41 surrounds the magnet 42 and front plate 43, leaving a gap that serves as the magnetic gap for the voice coil 3. The upper end of the U-shaped iron 41 is fixed to the bottom of the frame 1, which has a magnetic circuit mounting slot. The U-shaped iron 41 is inserted into the magnetic circuit mounting slot.

[0053] The positioning support 5 is generally annular, with its circular or geometric center located on the centerline O of the voice coil 3. The positioning support 5 comprises an outer edge 51, an inner edge 53, and a corrugated body 52 located between the outer and inner edges 51, 53. The corrugated body 52 comprises multiple concentrically arranged corrugations, resulting in a plurality of crests and troughs staggered along its diameter. In some embodiments, the outer edge 51 of the positioning support 5 is higher than the corrugated body 52. ​​In other embodiments, the inner edge 53 of the positioning support 5 is higher than the corrugated body 52. ​​In yet other embodiments, both the outer edge 51 and the inner edge 53 of the positioning support 5 are higher than the corrugated body 52. ​​The outer and inner edges 51, 53 can be flush or at different heights. Specifically, in the embodiment shown in FIG2 , both the outer edge 51 and the inner edge 53 of the positioning support 5 are higher than the corrugated body 52, with the outer edge 51 being higher than the inner edge 53.

[0054] It should also be noted that, for example, the troughs and / or crests may be located in the same plane, and the outer edge 51 and inner edge 53 may be bent from the plane where the troughs are located. Specifically, in this embodiment, the crests are located in the same horizontal plane, and the outer edge 51 and inner edge 53 may be bent upward from the horizontal plane where the troughs are located.

[0055] The following describes the connection of the positioning support 5. The outer edge 51 of the positioning support 5 is fixedly connected to the upper end of the basin frame 1 and / or the hanging edge 23 of the diaphragm 2, and the inner edge 53 of the positioning support 5 is fixedly connected to the back of the diaphragm 2.

[0056] The outer edge 51 of the positioning support 5 can be fixed to the overhang 23 of the diaphragm 2; the outer edge 51 of the positioning support 5 can also be fixed to the upper surface of the upper end of the frame 1. Specifically, as shown in Figure 3, in this embodiment, the outer edge 51 of the positioning support 5 is stacked between the upper end of the frame 1 and the overhang 23 and secured with glue. The outer edge 51 of the positioning support 5 is positioned horizontally to better fit the upper end of the frame 1 and the lower surface of the overhang 23 of the diaphragm 2.

[0057] The inner edge 53 of the positioning support 5 can be fixed to the back of the diaphragm body 21, specifically by gluing. As shown in Figure 4 , the inner edge 53 of the positioning support 5 gradually tilts inward from top to bottom to mate with the diaphragm body 21. Furthermore, the corrugated body 52 is connected to the higher side of the inner edge 53. In other words, the inner edge 53 of the positioning support 5 and the diaphragm body 21 are both thin, inclined sheets that fit well together, achieving a superior bonding effect. Furthermore, the inner edge 53 of the positioning support 5 is higher than the midpoint of the diaphragm body 21 in the vertical direction, further helping to reduce the vertical dimensions of the basin frame 1.

[0058] The loudspeaker further comprises a dust cap 6. The dust cap 6 covers the voice coil mounting hole of the diaphragm 2 and seals the top of the voice coil 3. The dust cap 6 is specifically glued to the diaphragm body 21.

[0059] This embodiment also provides a method for assembling the above-mentioned loudspeaker. Referring to FIG5 , the method comprises the following steps:

[0060] (1) Connect the positioning support 5 to the diaphragm 2 to form a pre-assembled component;

[0061] (2) Install the pre-assembled accessories on the basin stand 1.

[0062] In step (1), the outer edge 51 is bonded to the lower surface of the suspension 23, and the inner edge 53 is bonded to the back surface of the diaphragm body 21. Before or after step (1), the voice coil 3 and the dust cap 6 are connected to the diaphragm 2.

[0063] In step (2), the connected hanging edge 23 and the outer edge 51 of the positioning support piece 5 are placed on the upper end of the basin frame 1 and connected, wherein the outer edge 53 of the positioning support piece 5 is located between the hanging edge 23 and the upper end of the basin frame 1.

[0064] Prior to step (2), the magnetic driver 4 has already been pre-fixed to the frame 1. When the pre-assembled body and the frame 1 are fixed, the voice coil 3 is aligned with the magnetic gap of the magnetic driver 4; during the process of connecting the pre-assembled body and the frame 1, the voice coil 3 is inserted into the magnetic gap. At this point, the assembly of the speaker is complete.

[0065] This assembly method eliminates the need for a stepped surface within the frame 1 for bonding the positioning support 5, instead utilizing the upper surface of the upper end of the diaphragm 2. It also eliminates the need for applying glue to the center hole of the positioning support 5 to bond the voice coil 3 frame, reducing the complexity of the process and simplifying the speaker assembly process. Assembly of the positioning support 5 and diaphragm 2 can be completed in advance or performed at an auxiliary station, shortening the speaker assembly line.

[0066] Comparing the embodiment with a conventional cone-shaped speaker, when the sound radiation surface of the diaphragm is the same, the height of the speaker in the embodiment is significantly reduced.

[0067] In the speaker of this embodiment, the outer edge 51 of the positioning support 5 can be connected to the upper end of the chassis 1 and / or the overhang 23 of the diaphragm 2, and the inner edge 53 of the positioning support 5 can be connected to the back surface of the diaphragm body 21. There is no need to reserve additional installation space for the positioning support 5 on the voice coil 3 frame or the chassis, which can effectively reduce the size of the speaker in the direction of the motion axis. Typically, the height can be reduced to obtain a thin speaker, which requires less installation space on the vehicle and is more flexible and convenient to assemble the speaker on the vehicle.

[0068] Figure 6 shows another loudspeaker according to this embodiment. This speaker differs from the loudspeaker shown in Figures 1 to 4 in the shape of the diaphragm body 21 and the shape of the positioning support 5. As shown in Figure 6, in this loudspeaker, the diaphragm body 21 is positioned horizontally as a whole, forming a thin, horizontal sheet. The inner edge 53 of the positioning support 5 is also positioned horizontally, forming a thin, horizontal sheet. The two are in contact with each other. The inner edge 53 of the positioning support 5 is roughly flush with its outer edge 51.

[0069] Comparative Example:

[0070] Referring to Figure 7, the speaker in the comparative example differs from the speaker shown in Figures 1 to 4 in terms of positioning support 5 and bracket 1; otherwise, the speaker is essentially identical. As shown in Figure 7, in the comparative example, positioning support 5 is positioned horizontally, with its outer edge extending horizontally outward from the corrugated main body and its inner edge extending horizontally inward from the corrugated main body. Neither edge bends upward. The inner edge is glued to the frame of voice coil 3. Bracket 1 has a stepped shoulder 10 that forms a stepped surface 101 that mates with positioning support 5. The outer edge of positioning support 5 is glued to this stepped surface 101.

[0071] Comparing the loudspeaker shown in FIG. 1 to FIG. 4 with the loudspeaker of the comparative example, when the sound radiation surface of the diaphragm 2 is equal, the height of the loudspeaker of the comparative example is significantly greater than that of the loudspeaker of Example 1.
