Abstract
Description
Technical Field
[0001] This utility model relates to the field of Bluetooth speaker technology, and in particular to a waterproof Bluetooth speaker. Background Technology
[0002] A waterproof Bluetooth speaker is a wireless speaker designed for use in water. It typically connects to smartphones, tablets, or other audio source devices via Bluetooth to play audio. They are particularly suitable for outdoor use, such as at the poolside, on the beach, camping, in the shower, or in humid environments, allowing users to use them with confidence without worrying about damage from splashes or immersion. The waterproof performance of waterproof Bluetooth speakers is usually indicated by IP ratings (international protection standards), such as IPX5, IPX7, and IP68. The higher the number, the higher the protection level. IPX5: Prevents splashes of water but is not suitable for complete immersion; IPX7: Can be submerged for short periods; IP68: Can be submerged at a certain depth for extended periods, offering excellent waterproof performance. Based on these waterproof standards, the casing, buttons, and interfaces of waterproof speakers undergo special sealing treatment to prevent moisture and dust from entering. For example, many waterproof Bluetooth speakers use rubber sealing rings or waterproof coatings to protect internal electronic components. Waterproof speakers use waterproof materials for the speaker units, such as waterproof diaphragms and waterproof mesh covers, which not only resist moisture but also ensure sound quality.
[0003] However, existing waterproof Bluetooth speakers do not provide specific waterproof protection for the internal power supply. Since users do not need to touch the internal battery of the speaker in daily use, and the battery is prone to damage, burning, or even explosion when it comes into contact with water, it is essential to provide specific waterproof protection for the battery. Utility Model Content
[0004] Therefore, it is necessary to provide a waterproof Bluetooth speaker to address the technical problem of insufficient waterproof protection for the internal power supply in existing waterproof Bluetooth speakers.
[0005] A waterproof Bluetooth speaker includes a housing, a speaker unit, a PCB, and a battery. The speaker unit, PCB, and battery are all installed inside the housing. The housing includes a first mounting part and a second mounting part. One end of the first mounting part is correspondingly fastened to the second mounting part to form a complete housing structure. The speaker unit is installed in the first mounting part, and the PCB and battery are installed in the second mounting part.
[0006] The second mounting portion includes a first waterproof structure and a second waterproof structure. The first waterproof structure is disposed on the inner surface of the side wall of the second mounting portion, and the second waterproof structure is disposed on the inner surface of the bottom wall of the second mounting portion. The first waterproof structure extends a predetermined distance along the inner wall of the second mounting portion toward the first mounting portion, so that when the second mounting portion is connected to the first mounting portion, the first waterproof structure abuts against the bottom wall of the first mounting portion, thereby effectively ensuring the waterproofness between the first mounting portion and the second mounting portion. The second waterproof structure can be correspondingly matched with the battery, that is, the battery can be installed inside the second waterproof structure.
[0007] In one embodiment, the second mounting portion described above is configured as a cylindrical structure.
[0008] In one embodiment, the first waterproof structure described above is configured as a ring structure, thereby tightly fitting into the inner wall of the second mounting portion.
[0009] In one embodiment, the first waterproof structure is made of a flexible material. During assembly, the first waterproof structure can be interference-fitted with the first mounting part, thereby improving the connection and density between the first waterproof structure and the first mounting part.
[0010] In one embodiment, the aforementioned second waterproof structure is configured as a box structure to stably house the battery.
[0011] In one embodiment, the first mounting part includes an inner cylinder, an outer cylinder, and a steel mesh. One end of the inner cylinder is connected to the second mounting part, and the other end of the inner cylinder is used to mount the speaker unit. The outer cylinder is sleeved on the outside of the inner cylinder. The steel mesh is installed at the opening of the inner cylinder facing away from the second mounting part.
[0012] In one embodiment, the steel mesh is provided with a third waterproof structure, which is disposed on the side surface of the steel mesh facing the speaker unit, and the third waterproof structure can be connected to the speaker unit to achieve a sealed connection between the steel mesh and the speaker unit.
[0013] In one embodiment, the first mounting part further includes an acoustically waterproof and breathable fabric layer disposed between the steel mesh and the speaker unit, thereby enhancing the waterproof capability of the steel mesh.
[0014] In one embodiment, the acoustic waterproof and breathable fabric layer is provided with a first connecting part, which corresponds to and cooperates with the third waterproof structure, so that the acoustic waterproof and breathable fabric layer is connected to the third waterproof structure through the first connecting part.
[0015] In one embodiment, the edge of the third waterproof structure facing the speaker unit is bent inward to form a double-ring structure, and the end of the third waterproof structure facing away from the speaker unit has an opening, thereby forming an annular first mating groove.
[0016] In one embodiment, the first connecting portion is fitted into the first mating groove, thereby enabling the waterproof layer to be stably connected to the third waterproof structure.
[0017] In one embodiment, the steel mesh is further provided with a fourth waterproof structure, which is located at the edge of the side surface of the steel mesh facing away from the speaker unit, and extends outward to connect to the end face of the outer cylinder, thereby enhancing the waterproof performance between the steel mesh and the outer cylinder.
[0018] In one embodiment, a second connecting portion is provided at the edge of the aforementioned fourth waterproof structure.
[0019] In one embodiment, the outer cylinder end face is provided with a second mating groove, and the second connecting part is correspondingly fitted into the second mating groove.
[0020] In one embodiment, the side wall of the second mounting part is further provided with a plurality of clearance holes, and a plurality of interfaces and dials provided on the PCB can extend to the outside of the second mounting part through the plurality of clearance holes.
[0021] In one embodiment, the first waterproof structure is provided with a plurality of through holes, each of which corresponds to a plurality of clearance holes, so that the plurality of interfaces and dials provided on the PCB can extend to the outside of the second mounting part in sequence through the corresponding through holes and clearance holes.
[0022] In one embodiment, the aforementioned through holes can be interference-fitted with several interfaces and dials on the PCB to ensure the waterproof effectiveness of the first waterproof structure.
[0023] The aforementioned waterproof Bluetooth speaker uses a first waterproof structure and a second waterproof structure to provide waterproof protection for the PCB and battery within the second mounting section. Specifically, the first waterproof structure extends a predetermined distance along the inner wall of the second mounting section towards the first mounting section. Thus, when the second mounting section connects to the first mounting section, the first waterproof structure abuts against the bottom wall of the first mounting section, effectively ensuring the waterproofness between the first and second mounting sections to protect the PCB and battery. The second waterproof structure can be fitted with the battery, meaning the battery can be installed inside the second waterproof structure. This further protects the battery from water damage, burning, or explosion during use, thereby improving the safety of the waterproof Bluetooth speaker in environments with a high risk of water ingress.

[0035] Please see Figures 1 to 5This utility model discloses a waterproof Bluetooth speaker, which includes a housing 100, a speaker unit 200, a PCB 300, and a battery 400. The speaker unit 200, PCB 300, and battery 400 are all installed inside the housing 100. The housing 100 includes a first mounting part 110 and a second mounting part 120. One end of the first mounting part 110 is correspondingly fastened to the second mounting part 120 to form a complete housing 100 structure. The speaker unit 200 is installed in the first mounting part 110, and the PCB 300 and battery 400 are installed in the second mounting part 120, so that the first mounting part 110 forms an independent sound cavity, ensuring the output sound quality of the waterproof Bluetooth speaker. Specifically, the second mounting portion 120 includes a first waterproof structure 121 and a second waterproof structure 122. The first waterproof structure 121 is disposed on the inner surface of the side wall of the second mounting portion 120, and the second waterproof structure 122 is disposed on the inner surface of the bottom wall of the second mounting portion 120. The first waterproof structure 121 extends a predetermined distance along the inner wall of the second mounting portion 120 toward the first mounting portion 110, so that when the second mounting portion 120 is connected to the first mounting portion 110, the first waterproof structure 121 abuts against the bottom wall of the first mounting portion 110, thereby effectively protecting the first waterproof structure 121. The waterproofing between the mounting part 110 and the second mounting part 120 provides waterproof protection for the PCB 300 and the battery 400. The second waterproof structure 122 can cooperate with the battery 400, that is, the battery 400 can be installed inside the second waterproof structure 122. Thus, the second waterproof structure 122 can further waterproof protect the battery 400, thereby ensuring that the battery 400 will not be damaged, burned or exploded by water during use, thereby improving the safety of the waterproof Bluetooth speaker in environments with a high risk of water ingress.
[0036] Furthermore, the second mounting portion 120 is configured as a cylindrical structure, and correspondingly, the first waterproof structure 121 is configured as a ring-shaped structure, thereby tightly fitting onto the inner wall of the second mounting portion 120 to ensure the effectiveness of the waterproof function of the first waterproof structure 121. In one embodiment, the first waterproof structure 121 is made of a flexible material, and during assembly, the first waterproof structure 121 can be interference-fitted with the first mounting portion 110, thereby improving the connection and density between the first waterproof structure 121 and the first mounting portion 110. In another embodiment, the second waterproof structure 122 is configured as a box structure to stably house the battery 400.
[0037] Furthermore, the first mounting part 110 includes an inner cylinder 111, an outer cylinder 112, and a steel mesh 113. One end of the inner cylinder 111 is connected to the second mounting part 120, and the other end of the inner cylinder 111 is used to mount the speaker unit 200. The outer cylinder 112 is sleeved on the outside of the inner cylinder 111. The steel mesh 113 is installed at the opening of the inner cylinder 111 facing away from the second mounting part 120. Specifically, the steel mesh 113 is provided with a third waterproof structure 1131. The third waterproof structure 1131 is provided on the surface of the steel mesh 113 facing the speaker unit 200, and the third waterproof structure 1131 can be connected to the speaker unit 200 to achieve a sealed connection between the steel mesh 113 and the speaker unit 200.
[0038] Furthermore, the first mounting part 110 also includes an acoustically waterproof and breathable fabric layer 114, which is disposed between the steel mesh 113 and the speaker unit 200 to enhance the waterproof capability of the steel mesh 113. Specifically, the acoustically waterproof and breathable fabric layer 114 is provided with a first connecting part 1141, which corresponds to and cooperates with the third waterproof structure 1131. Thus, the acoustically waterproof and breathable fabric layer 114 is connected to the third waterproof structure 1131 through the first connecting part 1141, thereby ensuring the installation stability of the acoustically waterproof and breathable fabric layer 114.
[0039] Furthermore, the edge of the third waterproof structure 1131 facing the speaker unit 200 is bent inward to form a double-ring structure, and the end of the third waterproof structure 1131 facing away from the speaker unit 200 has an opening, thereby forming an annular first mating groove a. Specifically, the first connecting part 1141 is fitted into the first mating groove a, so that the waterproof layer can be stably connected with the third waterproof structure 1131, thereby improving the waterproof performance of the steel mesh 113.
[0040] Furthermore, the steel mesh 113 is also provided with a fourth waterproof structure 1132. The fourth waterproof structure 1132 is located at the edge of the surface of the steel mesh 113 facing away from the speaker unit 200, and extends outward to connect to the end face of the outer cylinder 112, thereby enhancing the waterproof performance between the steel mesh 113 and the outer cylinder 112. Specifically, a second connecting part 1133 is provided at the edge of the fourth waterproof structure 1132, and correspondingly, a second mating groove b is provided on the end face of the outer cylinder 112. The second connecting part 1133 is fitted into the second mating groove b, thereby further improving the waterproof performance between the steel mesh 113 and the outer cylinder 112.
[0041] Furthermore, the sidewall of the second mounting portion 120 is also provided with a plurality of clearance holes c. In one embodiment, a plurality of interfaces and dials provided on the PCB 300 can extend to the outside of the second mounting portion 120 through the clearance holes. Correspondingly, the first waterproof structure 121 is provided with a plurality of through holes d, each corresponding to one of the clearance holes c. Thus, the plurality of interfaces and dials provided on the PCB 300 can extend to the outside of the second mounting portion 120 in sequence through the corresponding through holes d and clearance holes c. More specifically, the plurality of through holes d can be interference-fitted with the plurality of interfaces and dials on the PCB 300 to ensure the waterproof effectiveness of the first waterproof structure 121.
[0042] In summary, the waterproof Bluetooth speaker disclosed in this utility model provides waterproof protection for the PCB and battery within the second mounting portion through a first waterproof structure and a second waterproof structure, respectively. Specifically, the first waterproof structure extends a predetermined distance along the inner wall of the second mounting portion toward the first mounting portion. Thus, when the second mounting portion connects to the first mounting portion, the first waterproof structure abuts against the bottom wall of the first mounting portion, effectively ensuring the waterproofness between the first and second mounting portions to protect the PCB and battery. The second waterproof structure can correspondingly cooperate with the battery, that is, the battery can be installed inside the second waterproof structure. Thus, the second waterproof structure can further protect the battery from water damage, burning, or explosion during use, thereby improving the safety of the waterproof Bluetooth speaker in environments with a high risk of water ingress.
[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
