Description

Technical Field

[0001] The present disclosure relates to a loudspeaker, and more particularly to a loudspeaker with batches of paper cones. Background Art

[0002] The sound system in the listening environment usually includes speakers distributed throughout the interior of the vehicle. Premium sound systems often include large subwoofers and dedicated amplifiers. In general, premium sound systems require a large amount of available space in the listening environment and a large number of locations within the available space where the speakers can be positioned. Configuring the sound system involves selecting the speaker locations in the listening environment. For listening environments with limited space (such as car cabins), positioning speakers (especially low-frequency working speakers such as subwoofers) and packaging constraints are a challenge. Generating low frequencies requires a larger cabin volume and transducer size. Therefore, in automotive scenarios, a compromise must be made between the size of the speaker cabinet and the size of the transducer, which usually limits the low-frequency cutoff of the sound system.

[0003] Additionally, smaller listening environments require smaller speakers, which are inherently less efficient than larger speakers at generating midrange and low frequencies. Listeners have expectations for bass performance, but smaller speakers can have a detrimental effect on it. Solutions such as psychoacoustic tuning attempt to compensate for the reduction in bass performance, but this comes at the expense of clarity and high-fidelity performance.

[0004] Another solution is to attempt a more compact speaker design by including passive radiators or using vented enclosures. However, each of these solutions has its own drawbacks. Passive radiators often cause the speaker to move noticeably, creating unwanted noise. Vented enclosures can expose the speaker to harsh environments. Additionally, such speaker designs are still subject to size / positioning constraints associated with the listening environment, requiring their design to be context specific.

[0005] What is needed in a loudspeaker is a transducer assembly that, unlike conventional loudspeakers, has scalable size variations to accommodate a variety of packaging conditions while maintaining performance. Summary of the invention

[0006] A speaker subassembly has at least one active section base section, at least one batch section, and passive end sections. In one or more embodiments, speaker subassemblies with batch cones can be attached to each other via adapter sections to create a dual core speaker with batch cones. In one or more embodiments, speaker subassemblies with batch cones can be assembled in parallel, or in line end-to-end.

[0007] In one or more embodiments, an expandable speaker assembly has: at least one electrically driven base segment having a motor and a voice coil driven by the motor; a passive end segment having a cone driven by the at least one electrically driven base segment; and a plurality of passive batch segments connected between the at least one electrically driven base segment and the passive end segment, each batch segment of the plurality of batch segments being stacked to provide an overall cone area for the expandable speaker assembly. In one or more embodiments, two expandable speaker assemblies can be attached to each other via an adapter segment to create a dual core speaker with batched cones. In one or more embodiments, multiple dual core speakers can be assembled parallel to each other, or assembled end-to-end in a straight line. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Although the reference Figures 1 to 16 Various aspects of the present disclosure have been described, but the present disclosure is not limited to such embodiments, and additional modifications, applications, and embodiments may be implemented without departing from the present disclosure. In the accompanying drawings, the same reference numerals will be used to illustrate the same components. Those skilled in the art will recognize that the various components set forth herein may be modified without departing from the scope of the present disclosure.

[0032] Figure 1 1 is a perspective view of one or more embodiments of an expandable speaker assembly 100 with batched cones. The expandable speaker assembly 100 with batched cones has at least one base section 200, one or more batch sections 300, and an end section 400. Each speaker assembly 100 with batched cones is expandable by the number and combination of base sections, batch sections, and end sections used in the assembly. Figure 1 In the illustrated embodiment, two expandable speaker assemblies 102 and 104 with batched cones may be attached to one another via an optional adapter segment 800 .

[0033] In-vehicle applications typically have packaging requirements that require the assembly to be as small as possible, but the audience's expectations for bass performance remain high. The expandable speaker assembly 100 with batched cones of the subject of the present invention presents more options for integrating the speaker 100 into the vehicle cabin, using very little packaging space while maintaining bass performance that meets or exceeds the audience's expectations. For example, one or more expandable speaker assemblies 100 with batched cones can be placed under the rear seats of the vehicle cabin, where they use the cavity under the rear seats as the working volume. Due to the size of the subwoofer, it is almost impossible to use a subwoofer with a traditional speaker in this location. However, the expandable speaker assembly with batched cones can accommodate multiple batch sections to provide more cone area. By stacking the radiating areas of multiple cones on top of each other, the assembly maintains the overall effective cone surface of the compact assembly, thereby enabling it to be packaged into a smaller space without limiting sensitivity or efficiency. In addition, the scalability of the batch sections allows for custom designs in different applications, limited only by the size of the location where the speaker assembly with batched cones will be installed.

[0034] Figure 1 One or more embodiments of an expandable speaker assembly 100 with a batch of cones are shown in FIG. The assembly 100 has at least one of a first subassembly and a second subassembly, namely, an expandable speaker 102, 104. Figure 1In the example arrangement shown in , two subassemblies 102, 104 with batch cones are arranged facing each other. Each speaker subassembly 102, 104 has an active end 102a, 104a with at least one active section located at a base section 200, at least one batch section 300, and a passive end 102b, 104b located at an end section 400. In one or more embodiments, the first expandable speaker 102 with batch cones is connected to the passive end 104b of the second expandable speaker 102 with batch cones at the passive end 102b through an optional adapter section 800 to configure the speaker as a dual-core speaker assembly 100 with batch cones. However, it should be noted that the expandable speakers 102, 104 with batch cones are not required to be connected as shown, and one of the first expandable speaker 102 with batch cones or the second expandable speaker 104 with batch cones can be a separate unit. It should be noted that the loudspeaker 102 , 104 units with batched cones may have fewer or more batch sections than shown in FIG. 2 .

[0035] It should be noted that the assembly 100 may include several expandable speakers 102 and 104 with batched cones arranged in a row within the same housing. It should also be noted that the assembly 100 may include more active elements (base sections 200) stacked on top of each other so that the motor forces of each base section 200 are summed.

[0036] Reference now Figure 2A and Figure 2B , a base section 200 is described. The base section 200 is an active unit, which means that it is electrically driven by a motor 204. The motor has magnets 207, which can be permanent block or ring neodymium magnets, or electromagnets. Figure 2A A perspective view of the base section 200 is shown in FIG. Figure 2B 2 shows a cross-sectional view of the base segment 200. Each base segment 200 has a base housing 202, which houses a motor assembly 204, a voice coil 205, a carrier tube 206 or a push rod (hereinafter referred to as a carrier tube), a paper cone 208, and a centering support 210 (or a suspension edge). The carrier tube 206 passes through the paper cone 208 and the centering support 210 from the voice coil 205 and provides support for the paper cone 208. The top end 212 of the carrier tube 206 has a flange 214 for connecting the base segment 200 to the batch segment ( Figure 2A or Figure 2B 206 has a predetermined length l such that the top end (or second end) 212 extends beyond the paper cone 208 and the top side 216 of the base housing 202. The carrier tube 206 may have a flange 214 for connecting to a carrier tube of an adjacent segment (not shown). In addition, the carrier tube 206 may be more than one component, such as Figure 2B shown.

[0037] exist Figure 2A and Figure 2B In the example shown in , the first side 222 of the cone 208 is coupled to a first resonator, such as a ventilated resonator of an adjacent housing (i.e., a batch section or an end section to be described below). The second side 218 of the cone 208 is coupled to a second resonator different from the first resonator, such as a resonator of the base housing 202. The second side 218 of the cone 208 is coupled to the second resonator through an opening 220 in the housing 202. For example, the opening 220 can lead to the vehicle cabin. Coupling the front radiated signal and the rear radiated signal to different resonators (the first resonator and the second resonator) prevents acoustic shorting.

[0038] Each batch section 300 is a passive unit of the loudspeaker assembly 100 with batch cones. Figure 3A A perspective view of the batch section 300 is shown. Figure 3B 300 has a batch section housing 302 that houses a carrier tube 306, a cone 308, and a suspension element 310 (such as a centering tab or hanging edge). The carrier tube 306 passes through the cone 308 and the suspension element 310 and provides support during deflection of the cone 308. The top end 312 of the carrier tube 306 has a flange 314 for connecting to another carrier tube or end section ( Figure 3A The bottom end 313 of the carrier tube 306 is configured to be attached to the base section ( Figure 3A or Figure 3B ) or another batch section 300 ( Figure 3A or Figure 3B The carrier tube 306 has a predetermined length l, so that the top end portion 312 with the flange 314 extends beyond the top side 316 of the batch section housing 302.

[0039] The first side 322 of the cone 308 in the batch section 300 is coupled to the first resonant body through the housing of an adjacent batch section or end section (not shown). The batch housing 302 has an opening 320 that couples the second side 318 of the cone 308 of the batch section to a second resonant body different from the first resonant body, such as a car body. The housing 302 attached to the adjacent batch section or end section (not shown) has an opening 326. In one example, the opening 326 provides exposure of the first surface 222 of the cone 208 in the base section 200 to the second resonant body.

[0040] The batch section 300 is a passive section. It is mechanically driven by a carrier tube 306, which is connected to support and / or center the voice coil 208 of the active base section 200, which is electrically driven by a magnet and voice coil, as described above with reference to Figure 2Bdescribed.

[0041] Figure 4A A perspective view of the end section 400 is shown. Figure 4B 4 shows a cross-sectional view of an end section 400. The end section 400 has an end section housing 402 that houses a carrier tube 406, a paper cone 408, and a centering support 410 (or overhang). The carrier tube 406 passes through the paper cone 408 and the centering support 410 and provides support for the paper cone 408. The bottom end 413 of the carrier tube 406 has a flange 414 for connecting to the batch section 300 ( Figure 4A and Figure 4B 4. The carrier tube 406 is provided with a carrier tube (not shown in FIG. 4). The top end portion 412 of the carrier tube 406 has a dust cover 424. The carrier tube 406 has a predetermined length l so that the top end portion 412 with the dust cover 424 extends beyond the top side 416 of the end section housing 402. The first side 422 of the cone 408 in the end section 400 is exposed to the resonant body through, for example, an adjacent housing (not shown). The batch housing 402 has an opening 420, which couples the second side 418 of the cone 408 to the second resonant body. The opening 426 couples the resonant bodies of the first sides 222, 322 of the cone 208, 308 of the adjacent section (the base section 200 or the batch section 300).

[0042] As described above, there is no motor assembly in one or more batch sections 300 or in the end sections 400. Instead, the batch sections 300 and the end sections 400 are mechanically driven by their connection to the base section and / or to each other. For example, the carrier tubes 306 of the batch sections 300 can be connected to each other and to the carrier tubes 406 in the end sections 400. Finally, the passive sections 300, 400 are mechanically driven by using carrier tubes and / or push rods between each passive section 300, 400 and the electrically driven active section 200. This can be achieved by connecting the cones 308, 408 of each batch section and the end section to the carrier tubes 306, 406.

[0043] Alternatively, the cones 308, 408 of the batch section 300 and end section 400 may not be connected to the carrier tubes 306, 406. In this example, the sections 300 and 400 act as passive radiators whose resonant frequencies can be tuned by the suspension forces and weight to extend the low frequencies.

[0044] The housings 202, 302 and 402 may be mechanically fastened to one another. The openings should be aligned. For example, the opening 220 in the base segment housing 202 should be aligned with the opening 320 in each batch segment housing 302 and the opening 420 in the end segment housing 402.

[0045] In one or more embodiments, a speaker assembly 500 with batch cones may include at least one base section 200 and at least one end section 400. One or more batch sections 300 may be connected between the base unit 200 and the section 400. For example, Figure 5 A cross-sectional view of a speaker assembly 500 with batch cones is shown, the speaker assembly having a base section 200, first and second batch sections 300a, 300b attached thereto, and an end section 400 attached to one of the batch sections 300b. The first batch section 300a is attached to the base section 200, the second batch section 300b is attached to the first batch section 300a, and the end unit batch section 400a is attached to the second batch section 300b. The number n of batch sections 300 can extend 300a-300n and can vary depending on packaging constraints, performance considerations, etc. It should be noted that the speaker assembly with batch cones can also have only one base section 200 and one end unit 400 without the intermediate batch section 300.

[0046] exist Figure 5 In one or more embodiments shown, the speaker assembly 500 with batched cones has an integral carrier tube 206. It should be noted that this is shown for exemplary purposes only, and as described above, the carrier tube can be multiple components. In yet another example, the carrier tube can be one or more push rods. The design of the speaker assembly with batched cones with one or more push rods or the carrier tube of one or more components can depend on its specific use in the environment and the packaging location of the assembly.

[0047] The speaker assembly with batched cones 500 may be self-contained. In one or more embodiments of a self-contained speaker assembly with batched cones, a cover section 600 may be attached to the passive end. Fig. 6A A perspective view of the cover segment 600 is shown. Figure 6B A cross-section of a cover segment 600 is shown. The cover segment 600 has a cover housing 602 with an opening 626 that couples to a corresponding resonator, e.g., a first resonator of a first side of a cone of an adjacent segment, e.g., the batch segment 300 or the end segment 400.

[0048] Fig. 7A is a perspective view of one or more embodiments of a loudspeaker 700 with batch cones, showing a base section 200 , two batch sections 300 a , 300 b , an end section 400 , and a cover section 600 . Figure 7B 7 is a cross-sectional view. The first batch of segments 300a is attached to the base segment 200 and the second batch of segments 300b is attached to the first batch of segments 300a. The end segment 400 is attached to the second batch of segments 300b. In the example shown in FIG. 7 , the cover segment 600 is attached to the end segment 400.

[0049] As discussed previously herein, in one or more embodiments, speakers 700 with batched cones may be attached to one another via adapter segments 800 to create a dual core speaker with batched cones. Fig. 8A is a perspective view of adapter segment 800. Figure 8B 8 is a cross-sectional view of an adapter section 800. The adapter section 800 is a housing 802 configured to fasten the end sections of each loudspeaker 700 with batch cones to each other. The adapter 800 has an opening 820 coupled toward the resonator and an opening 826 coupled toward the corresponding resonator (the first resonator or the second resonator) to avoid acoustic short circuits.

[0050] Fig. 9 is a perspective view of one or more embodiments showing two speaker assemblies 500a and 500b with batched cones joined by an adapter segment 800 to create a dual core speaker assembly 900 with batched cones. Fig. 9 800 is a cross-sectional view of a dual-core speaker with a batch of paper cones 900. The passive end 502b of the first speaker with a batch of paper cones 500a is joined to the passive end 504b of the second speaker with a batch of paper cones 500b at the adapter section 800.

[0051] Fig.10 1 is a cross-sectional view of one or more embodiments of a base section 1000 having a carrier tube 1002, the diameter of which may ideally, but not limited to, be less than or equal to the diameter 1006 of the voice coil 1003 driving the active unit. For example, the first end 1004 of the carrier tube 1002 has a first diameter 1006, which is about as large as the diameter 1006 of the voice coil 1003 to ensure high performance of the motor. The second end 1008 of the carrier tube 1002 has a second diameter 1010, which may be smaller than the first diameter 1006 to allow for a larger cone surface, thereby contributing to the effective overall cone area of ​​the entire assembly.

[0052] Fig.11 is a cross-sectional view of one or more embodiments of a speaker 1100a with a batch of cones having a Fig.10 1104 at the base section 1104 discussed in . Each batch section 1106, 1108 has a carrier tube 1110 whose diameter matches the reduced diameter of the carrier tube 1102 of the base section. The end unit 1112 has a carrier tube 1114 whose diameter matches the diameter of the carrier tube 1110 of the batch sections 1106, 1108. An inner flange 1116 may be added to the carrier tube of the batch section 1106 to provide more overall effective cone surface.

[0053] In one or more embodiments, the loudspeaker with batch cones has no additional push rods or tube carrying elements. See, e.g. Figure 7B 200 to which additional batch cones, surrounds or centering pads can be directly attached. It should be noted that a combination in which a single push rod or carrier tube extends from the voice coil in the base section 200 through additional sections, batch cones, surrounds or centering pads is also possible.

[0054] For one or more embodiments having a carrier tube with multiple components, there are several alternatives for connecting the carrier tube components. For example, Fig.12 A cross-sectional exploded view of one or more embodiments of an arrangement 1200 for connecting carrier tubes 1202a, 1202b between various segments is shown. The mating end 1204a of the first carrier tube 1202a has a flange 1206a extending perpendicularly to the carrier tube around the circumference of the carrier tube 1202a. The mating end 1204b of the second carrier tube 1202b has a flange 1206b extending perpendicularly to the second carrier tube 1202b around the circumference of the second carrier tube 126b, such that the mating ends 1204a, 1204b of the carrier tubes 1202a, 1202b abut against each other when assembled and meet circumferentially at the flanges 1206a, 1206b. The mating ends may be bonded at the flanges 1206a, 1206b.

[0055] Fig.13 A cross-sectional exploded view of one or more embodiments of an arrangement 1300 for connecting carrier tubes 1302a, 1302b between various segments is shown. The mating end 1304a of the carrier tube 1302a has a circumferential collar 1306. The inner diameter of the collar 1306 can receive the outer diameter of the mating end 1304b of the carrier tube 1302b. The connection can be strengthened by bonding the carrier tubes 1302a, 1302b at the connection.

[0056] Fig.14 A cross-sectional exploded view of one or more embodiments of an arrangement 1400 for connecting carrier tubes 1402a, 1402b between various segments at mating ends 1404a and 1404b of the carrier tubes 1402a, 1402b is shown. The mating ends 1404 of each carrier tube 1402a, 1402b abut one another coaxially and may be bonded together. A support ring 1406 is externally coupled to the outer diameter of each carrier tube 1402a, 1402b. The support ring 1406 may be bonded to the outer periphery of the carrier tubes at their respective mating ends 1404a, 1404b.

[0057] It should be noted that the batch section may have centering tabs instead of overhangs, such as Fig.15 shown. Fig.15A cross-sectional view of a portion of a base section 1502 and a batch section 1504 of a loudspeaker assembly 1500 with a batch cone is shown. The batch section 1504 has a centering spider 1506 that is centered by a carrier tube and is attached to the batch section housing 1506. A flange 1508 is located at the top of the batch section housing.

[0058] Fig.16 A cross-sectional view of a base section 1602 and a batch section 1604 of a speaker assembly 1600 with a batch cone is shown. The batch section 1604 has a flange 1606 attached to the bottom of the housing and a flange 1608 attached to the top of the housing. Fig.16 In the embodiment shown in , the flange 1606 is in the opposite direction to the flange 1608. It should be noted that the flange 1606 and the flange 1608 can have the same direction. The flange geometry is used to separate the back and front sides of the radiating area to avoid acoustic shorting and vent noise. The flange can also serve as an additional guiding feature to control the direction of the carrier tube / push rod. The flange geometry described herein is for example purposes only, and it should be noted that other elements can also achieve sound separation. For example, a foam surround.

[0059] The loudspeaker assembly with batched cones that is the subject of the present invention can be very easily scaled based on performance requirements, packaging requirements, while maintaining a small package.
