[0029] This utility model provides a portable speaker 10 based on 3D printing, aiming to improve the utilization of the speaker's internal space while achieving long battery life, and also facilitating quick battery replacement. Figure 1 and Figure 2 As shown, the portable speaker 10 includes: a base 100, a protective shell 200, a speaker (not shown), an integrated controller (not shown), and a power module 300. The integrated controller is installed inside the base 100, the protective shell 200 is disposed on the base 100, and the interior of the protective shell 200 forms a receiving cavity 201, in which the speaker and the power module 300 are housed.

[0030] like Figure 2 and Figure 3 As shown, the power module 300 includes: an end face base 310, a connector base 320, and a lithium battery 330. There are multiple lithium batteries 330, with three lithium batteries forming a group. Adjacent groups of lithium batteries 330 are connected by two connector bases 320. The ends of the first and last groups of lithium batteries 330 are connected to the end face base 310.

[0031] Among them, such as Figure 4 As shown, the connector 320 is provided with a limiting through hole 321, a mating surface 322, and a mounting surface 323. The limiting through hole 321 is connected to the end of the lithium battery 330. When the two connectors 320 are engaged, the two mating surfaces 322 are in contact with each other, and the lithium battery 330 is inserted into the limiting through hole 321 through the mounting surface 323.

[0032] Connector 320 has a triangular structure (e.g.) Figure 4 (As shown). The connector 320 has three sides, one of which has a snap hook 324, and the other two sides have grooves 325 that fit the snap hook 324. When two connectors 320 are engaged, the two mating surfaces 322 fit together, the snap hook 324 of the first connector 320 is inserted into the groove 325 of the second connector 320, and the snap hook 324 of the second connector 320 is inserted into the groove 325 of the first connector 320. Furthermore, after the two connectors are engaged, the grooves 325 on them in the idle state are aligned with each other.

[0033] The multiple connectors 320 have identical structures. When mating is required, only two connectors 320 need to be removed and fitted onto the ends of the two sets of lithium batteries 330. Then, one connector 320 is rotated, and the two connectors 320 are pressed together so that the two mating surfaces 322 are in contact, thus combining the two connectors 320 and achieving the combined connection of the two sets of lithium batteries 330. The specific connection process will be described below. Preferably, both the snap hook 324 and the connector 320 are made of insulated plastic, and the snap hook 324 and the connector 320 are integrally formed.

[0034] The connector 320 and end face seat 310 of this utility model are manufactured using 3D printing technology. 3D printing (3DP), also known as additive manufacturing technology (AM), is a technology that manufactures solid parts by adding materials layer by layer based on three-dimensional CAD data. 3D printing technology overcomes the limitations of traditional manufacturing methods. Traditional manufacturing methods, such as wooden lathes, rolling mills, and molding machines, are limited by their tools and processes, and can only produce products of specific shapes; while 3D printing technology can manufacture complex geometric shapes that are difficult or even impossible to process using traditional methods. At the same time, a major advantage of 3D printing technology is that it eliminates the need for assembly. Traditional production methods rely on assembly lines and production lines to produce various parts, which are then assembled by robots or workers. This multi-step process not only increases time and cost but also lengthens the supply chain, while 3D printing technology can directly mold parts into a single piece. As with the connector 320 and end face seat 310 of this utility model, 3D printing technology can manufacture them at low cost and quickly.

[0035] In this embodiment, to further prevent misalignment or slippage of the two connectors 320, the mating surface 322 of the connectors 320 is provided with a positioning pin 326 and a positioning hole 327 (e.g., Figure 4 (As shown). When the two connectors 320 are engaged, the positioning pin 326 of the first connector 320 is inserted into the positioning hole 327 of the second connector 320, and the positioning pin 326 of the second connector 320 is inserted into the positioning hole 327 of the first connector 320.

[0036] The design principle of the power module 300 will be explained below in conjunction with the above structure:

[0037] Taking three sets of lithium batteries 330 as an example, before assembly, two end face seats 310 and four connecting seats 320 need to be manufactured in advance.

[0038] During assembly, the connector 320 is first fitted onto the end of each lithium battery 330. When fitting each connector 320, the end of the lithium battery 330 is inserted into the limiting through hole 321 through the mounting surface 323. Then, two sets of lithium batteries 330 are combined. Specifically, the two connectors 320 of the two sets of lithium batteries 330 are brought close together, and one connector 320 is rotated so that the two mating surfaces 322 face each other. Then, the two connectors 320 are pressed together so that the two mating surfaces 322 are in contact. At this point, the buckle 324 of the first connector 320 is inserted into the groove 325 of the second connector 320, and the buckle 324 of the second connector 320 is inserted into the groove 325 of the first connector 320. In this way, the two connectors 320 are interlocked and combined into a single unit, thus connecting and assembling the two sets of lithium batteries 330.

[0039] Similarly, the third set of lithium batteries 330 is connected to the first two sets of lithium batteries 330 using the connector 320 again; then the end face bracket 310 is fitted onto the two ends of these three sets of lithium batteries 330, thus completing the combination of the power module 300. These three sets of lithium batteries 330 are connected in series and parallel through the circuits inside the connector 320 and the end face bracket 310, thereby forming a whole DC power supply.

[0040] Compared with existing technologies, this utility model combines multiple lithium batteries 330 together using a connecting base 320 and an end face base 310. The combined power module 300 fits the internal space of the receiving cavity 201, and the power module 300 can combine multiple lithium batteries 330 into a whole without the need for an additional outer shell, which improves the utilization rate of the internal space of the receiving cavity 201. In this way, a long battery life is achieved by utilizing the number of lithium batteries 330. At the same time, the power module 300 is simple and convenient to disassemble. When one or a group of lithium batteries 330 is damaged, the user can easily and quickly remove and replace it. In addition, the number of lithium battery groups in the power module 300 can be adjusted according to the height of the protective shell 200, thereby adapting to the size of different models of portable speakers 10.

[0041] In this embodiment, a positioning groove 311 is provided on the side of the end face seat 310 (e.g., Figure 3 As shown in the figure, the protective housing 200 has a positioning block (not shown) that mates with the positioning groove 311. When the power module 300 is received into the receiving cavity 201, the positioning groove 311 of the end face seat 310 will engage with the positioning block to prevent the power module 300 from being misaligned.

[0042] In this embodiment, if Figure 5As shown, the protective shell 200 has a prismatic structure, with several sound outlets 201 formed on its prismatic surface. A speaker is fitted onto the inner side of the prismatic surface of the protective shell 200 and faces the sound outlets 201. The speaker is electrically connected to the integrated controller inside the base 100, and the power module 300 is also electrically connected to the integrated controller. Preferably, the protective shell 200 also has an LED light strip 210, located between two adjacent prismatic surfaces, and electrically connected to the integrated controller. The LED light strip 210 flashes and illuminates in accordance with the rhythm of the music, thereby increasing the visual appeal.

[0043] It is important to emphasize that the prism structure design of the protective shell 200 allows for speakers to be placed in all directions, ensuring consistent sound from all angles of the portable speaker 10. Furthermore, the LED light strip 210 is positioned between adjacent prisms, ensuring that at least one LED light strip 210 is visible to the user regardless of their position on the portable speaker 10.

[0044] Preferably, the protective shell 200 and the base 100 are integrally formed, such as Figure 2 As shown, the protective housing 200 is provided with a top cover 220, which is detachably installed at the opening of the receiving cavity 201 by screws 221.

[0045] Preferred, such as Figure 5 As shown, the base 100 is equipped with a control switch 110 and a charging port 120, both of which are electrically connected to the integrated controller. The control switch 110 is used to start the portable speaker 10 with one button, and the charging port 120 is used to charge the lithium battery 330.

[0046] Preferably, in order to lower the center of gravity of the portable speaker 10, a counterweight (not shown) is provided at the bottom of the base 100, thereby preventing the portable speaker 10 from easily tipping over due to an excessively high center of gravity. Furthermore, the counterweight can also be made of permanent magnet material, which not only lowers the center of gravity but also provides multiple placement options, such as attaching it to a refrigerator door.

[0047] In summary, the portable speaker 10 based on 3D printing of this utility model can improve the utilization rate of its internal space while achieving long battery life, and at the same time facilitates the quick replacement of the lithium battery 330.

[0048] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
