[0002] Audio equipment is short for audio system, referring to a complete set of devices that can reproduce and play audio signals.

[0003] In existing technology, an audio system includes a cabinet, a back panel, and a front panel. A mounting plate is provided inside the cabinet to secure the various functional components of the audio system. The front panel is mainly covered with acoustically transparent cloth, through which the sound emitted by the audio system is transmitted. The speaker's sound propagation direction is towards the front panel, and the speaker's wiring direction is towards the back panel. A waterproof groove is provided at the mounting positions of the back panel and the cabinet. The waterproof groove is located along the edge of the cabinet and is ring-shaped. Waterproof material is placed inside the waterproof groove, and the waterproof material matches the shape of the groove, forming a ring structure. The mounting part of the back panel is embedded into the waterproof groove of the cabinet, and the waterproof material is located in the space between the mounting part of the back panel and the waterproof groove of the cabinet, thereby achieving a waterproof effect.

[0004] In existing technologies, in order to achieve a waterproof effect, the ring structure of waterproof materials often needs to be cut directly from a whole sheet of waterproof material to obtain a complete ring structure, resulting in a large amount of material waste. At the same time, because the shape of the waterproof material ring obtained directly from a whole sheet of waterproof material is difficult to match precisely with the waterproof groove, the waterproof performance at the joint between the back panel and the box body is poor. Summary of the Invention

Where there is no conflict, the various features in the embodiments and examples of this invention can be combined with each other, all of which are within the scope of protection of this invention.

[0047] Example 1:

[0048] like Figure 1 and Figure 2 As shown, Embodiment 1 of the present invention discloses a waterproof speaker, including a cabinet 1 and a back panel 2;

[0049] The housing 1 is provided with a waterproof groove 101, which is located at the corresponding installation position of the housing 1 and the back plate 2, and at least a portion of the back plate 2 is embedded in the waterproof groove 101;

[0050] It also includes sealant 3, which fills the waterproof groove 101;

[0051] When the back plate 2 is installed on the housing 1, the sealant 101 forms a seal at the gap where the housing 1 and the back plate 2 meet.

[0052] Specifically, the speaker enclosure 1 and back panel 2 are detachable components. Water can enter the speaker through the gaps after assembly, causing internal damage. Therefore, a waterproof structure is provided at the connection point between the enclosure 1 and the back panel 2. Figure 2The waterproof groove 101 shown is set along the wall of the box body 1 and is a through groove. Before the box body 1 and the back panel 2 are assembled, sealant 3 is injected into the waterproof groove 3. Then the box body 1 and the back panel 2 are assembled. The mounting part 21 of the back panel 2 is embedded in the waterproof groove 101. The sealant 3 in the waterproof groove 101 fills the remaining space of the mounting part 21 and the waterproof groove 101 to achieve a sealing effect.

[0053] In one embodiment:

[0054] Preferably, such as Figure 2 As shown, the back panel 2 includes a mounting part 21, which is provided with a mounting clip 211, and the width of the mounting clip 211 matches that of the waterproof groove 101.

[0055] Preferably, when the back plate 2 and the box 1 are assembled, the mounting clip 211 is embedded in the waterproof groove 101.

[0056] Specifically, when the mounting part 21 of the back panel 2 is installed into the waterproof groove 101 of the housing 1, the mounting clip 211 of the mounting part 21 is embedded in the waterproof groove, and the top surface of the first side wall 1011 of the waterproof groove abuts against the bottom surface of the back panel 2, thus completing the assembly.

[0057] In another embodiment:

[0058] Preferably, such as Figure 2 As shown, the mounting clip 211 has an extension 212 in the direction of the bottom of the waterproof groove 101, and the extension 212 is used for the installation guide of the back plate 2 and the box body 1.

[0059] Preferably, such as Figure 2 As shown, the extension 212 is provided with a shaping structure 213 in the direction toward the center of the waterproof groove 101, and the shaping structure 213 is arc-shaped.

[0060] Specifically, to facilitate the assembly of the back panel 2 and the housing 1 and reduce collisions, an installation guide structure, namely an extension 212 located at the front end of the mounting clip 211, is provided on the mounting part 21. Furthermore, to prevent the sealant 3 from detaching from its contact surfaces (the contact points between the sealant 3 and the back panel 2, and between the sealant 3 and the waterproof groove 101 of the housing 1) after the housing 1 and back panel 2 are installed, the bottom of the waterproof groove 101 has an arc-shaped structure. Simultaneously, a shaping structure 213 is provided at a position corresponding to the arc-shaped structure of the waterproof groove 101 on the extension 212, and the shape of this shaping structure 213 matches the arc-shaped structure of the waterproof groove 101. Preferably, the shaping structure 213 and the arc-shaped structure of the waterproof groove 101 form a ring, thus the shaping structure 213 preferably has an arc-shaped structure that matches the bottom arc shape of the waterproof groove 101. This improves the sealing effect.

[0061] The waterproof speaker using Embodiment 1 is assembled by injecting sealant 3 into the waterproof groove 101, and then assembling the back panel 2 with the cabinet 1 via the mounting part 21. The mounting clip 211 of the mounting part 21 is embedded into the waterproof groove 101 of the cabinet 1. The sealant 3 in the waterproof groove 101 seals the gap between the mounting part 21 and the waterproof groove 101, resulting in a good sealing effect and less waste of sealing materials.

[0062] Example 2:

[0063] The waterproof speaker of Embodiment 2 of the present invention is an improvement on Embodiment 1, such as... Figure 3 and Figure 4 As shown:

[0064] Preferably, the waterproof groove 101 includes a first sidewall 1011 and a second sidewall 1012. The distance from the second sidewall 1012 to the outer wall of the box 1 on the same side is less than the distance from the first sidewall 1011 to the outer wall of the box 1 on the same side. The second sidewall 1012 is provided with a drainage inlet 1013, and the drainage inlets 1013 are arranged at preset intervals along the length direction of the waterproof groove 101. The drainage inlets 1013 are above the waterproof groove 101, and the distance from the drainage inlet 1013 to the bottom of the waterproof groove 101 is greater than the distance from the front end of the mounting part 21 to the waterproof groove 101. The drainage outlet 1014 is located in the direction from the drainage inlet 1013 to the bottom of the waterproof groove 101. The outer wall of the box 1 is provided with a drainage outlet 1014 at a corresponding position of the drainage inlet 1013. The drainage inlet 1013 and the drainage outlet 1014 are connected by a drainage groove 1015.

[0065] Specifically, in the presence of water, to better waterproof the speaker, a drainage channel 1015 is provided at the assembly position of the back panel 2 and the cabinet 1. When water enters through the gap, it can be guided to the outside of the speaker cabinet 1 through the drainage channel 1015. To reduce water retention in the waterproof groove and / or at the contact point between the cabinet 1 and the back panel 2, the drainage inlet 1013 of the drainage channel 1015 is located on the side wall of the waterproof groove 101 near the outer wall of the cabinet 1, and is arranged at preset intervals along the length of the waterproof groove 101 (i.e., combined with...). Figure 1 As shown, a ring of drainage inlets is provided at preset intervals on the second side wall 1012 of the waterproof groove 101, that is, the drainage inlets 1013 are set on the second side wall 1012, and the location of the drainage inlets 1013 corresponds to the middle area of ​​the mounting part 21 of the back plate 2; in order to facilitate rapid drainage, the drainage outlet 1014 provided on the outer wall of the enclosure 1 is set in the direction of the drainage inlet 1013 toward the bottom of the waterproof groove 101 (that is, the drainage inlet 1013 and the drainage outlet 1014 have a certain slope in the depth direction of the waterproof groove 101), which speeds up the water flow; in order to remove the water that has entered the speaker as quickly as possible, the drainage outlet 1014 is set on the outer wall of the enclosure 1 corresponding to the drainage inlet 1013 (that is, the direction from the drainage outlet 1014 to the drainage inlet 1013 is parallel to the width direction of the waterproof groove), which can reduce the length of the drainage groove 1015, so that the water is discharged with the shortest distance.

[0066] In yet another embodiment:

[0067] Preferably, such as Figure 4 and Figure 5 As shown, on the mounting portion 21 of the back plate 2, a submerged structure 214 is provided at a position corresponding to the drainage inlet 1013. The width of the submerged structure 214 matches the size of the drainage inlet 1013. The submerged structure 214 is arranged along the length direction of the waterproof groove 101. A diversion inlet 217 is provided on the contact surface between the mounting portion 21 and the second side wall 1012. The diversion inlets 217 are arranged at preset intervals along the length direction of the waterproof groove 101. A diversion outlet 215 is provided in the submerged structure 214. The diversion inlet 217 and the diversion outlet 215 are connected through the diversion groove 216. The distance from the diversion inlet 217 to the bottom of the waterproof groove 101 is greater than the distance from the submerged structure 214 to the bottom of the waterproof groove.

[0068] Preferably, such as Figure 6 As shown, the diversion channel 216 and the diversion channel 1015 are alternately arranged along the length direction of the waterproof groove 101.

[0069] Specifically, to improve the waterproof performance of the speaker and to increase the drainage range of the drainage channel 1015 on the outer shell of the enclosure 1, a submersible structure 214 is provided on the mounting portion 21 of the back panel 2 at a position corresponding to the drainage inlet 1013 of the drainage channel 1015. This submersible structure 214 is arranged along the length of the waterproof groove 101. Figure 1 The waterproof groove 101 is an annular groove, so the submersible structure 214 is also an annular structure. The submersible groove 214 can collect water in the area between two adjacent drainage inlets 1013 and then discharge it out of the speaker through the drainage inlets. In order to accelerate the flow of water between the two adjacent drainage inlets 1013 into the submersible structure 214 as soon as possible, a diversion channel 216 is provided above the submersible structure 214 (i.e., away from the waterproof groove 101). The diversion channel 216 and the drainage channel 1014 are alternately arranged to ensure that the water entering the mounting part 21 of the cabinet 1 and the back panel 2 can be completely discharged through the drainage channel, thereby improving the waterproof effect of the speaker.

[0070] In yet another embodiment:

[0071] Preferably, such as Figure 7 As shown, the outer side of the box 1 is provided with a guide groove 1017 at the corresponding position of the drain outlet 1014, and the direction of the guide groove 1017 is away from the direction of the back plate 2.

[0072] Specifically, the outer shell of the housing 1 has a flow inlet 1016 at the location of the flow outlet 1014, and the housing 1 has a flow outlet 1018 at the depth direction of the waterproof groove 101 and away from the edge of the back plate 2. The flow inlet 1016 and the flow outlet 1018 are connected by a flow channel 1017, thereby draining the water from the flow outlet 1014 and preventing the water from the flow outlet 1014 from flowing irregularly.

[0073] The waterproof speaker using Embodiment 2 can quickly drain water that has entered the speaker through the drainage channel 1015, and at the same time, the water can be guided out in a predetermined manner through the guide channel 1017, thereby improving the drainage effect.

[0074] By setting up a submersible structure 214, water in the area between two adjacent drainage channels 1014 can be collected and then discharged by the drainage channel 1014. By alternately setting up drainage channels 1014 and diversion channels 216, it can be ensured that water in the gap between the speaker cabinet 1 and the back panel 2 is completely discharged.

[0075] Meanwhile, by setting up the diversion channel 1014, the submersible structure 214 and the diversion channel 216, the water entering the speaker is removed in three stages, which improves the efficiency and reliability of drainage.

[0076] The remaining structure and working principle of Example 2 are the same as those of Example 1.

[0077] Example 3:

[0078] The waterproof speaker of Embodiment 3 of the present invention is an improvement on Embodiment 1, such as... Figure 7 , Figure 8 and Figure 9 As shown:

[0079] Preferably, the speaker also includes a plurality of foot pads 5 disposed at the bottom of the enclosure 1.

[0080] Preferably, the foot pad 5 is an air spring foot pad, and the air spring foot pad has a receiving cavity 503 inside, the receiving cavity 503 is filled with gas, and the air spring foot pad is used to buffer the vibration generated by the speaker.

[0081] Specifically, the foot pad 5 includes a mounting surface 501 and a contact surface 502, the mounting surface 501 and the contact surface 502 forming a cavity 503 for accommodating elastic gas; the contact surface 502 abuts against the ground, the mounting surface 501 is mounted on the bottom surface of the speaker enclosure 1, and the cavity 503 is filled with air or inert gas.

[0082] In use, the receiving cavity 503 is a sealed cavity (it can be a sealed cavity directly formed between the mounting surface 501 and the contact surface 502, or it can be an open cavity directly formed between the mounting surface 501 and the contact surface 502. In use, the mounting surface 501 and the bottom surface of the speaker enclosure 1 are sealed, thus sealing the open cavity into a sealed cavity). When the speaker vibrates, a pressure is transmitted to the mounting surface 501 through the bottom surface of the enclosure 1. The contact surface 502 will be subjected to a reaction force generated by the ground or other bearing surface. Under the combined action of this pressure and reaction force, the volume of the receiving cavity 503 decreases, thus increasing the pressure inside the receiving cavity 503. The gas inside the receiving cavity 503 generates an opposite force to restore the volume of the receiving cavity 503 and restore the original cavity pressure, thereby weakening the force transmitted by the device.

[0083] In one embodiment:

[0084] Preferably, such as Figure 8 and Figure 10 As shown, the mounting surface 501 is provided with a through hole 504, the bottom surface of the speaker enclosure 1 abuts against the mounting surface 501, and the receiving cavity 503 forms a sealed cavity.

[0085] Specifically, when the receiving cavity 503 of the foot pad 5 is an open cavity, when the foot pad 5 is installed on the equipment through the mounting surface 501, the through hole 504 is sealed by the mounting part of the equipment, so that the receiving cavity 503 becomes a sealed cavity to prevent gas leakage.

[0086] In yet another embodiment:

[0087] Preferably, such as Figure 9 As shown, the mounting surface 501 is a plane, and the contact surface 502 is an arc surface, combined with... Figure 8 As shown, the mounting surface 501 and the contact surface 502 form a hemispherical structure.

[0088] Specifically, the foot pad 5 is designed as a hemispherical structure, and the mounting surface 501 of the planar structure can increase the load-bearing area of ​​the bottom surface of the speaker enclosure 1.

[0089] In yet another embodiment:

[0090] Preferably, the foot pad 5 further includes a shaping portion 105, which is disposed along the edge of the contact surface 502.

[0091] Preferably, the shaping part 105 has a ring-shaped structure.

[0092] Preferably, the mounting surface 501, the contact surface 502, and the shaping part 105 are integrally molded structures.

[0093] Specifically, such as Figure 8 and Figure 10 As shown, a shaping part 105 is provided between the edges of the mounting surface 501 and the contact surface 502. The foot pad 5 is integrally molded, which can ensure the stability of the structure and improve the service life.

[0094] The foot pad 5 of Embodiment 1 not only supports the speaker but also cushions the impact force generated by the speaker placement, preventing equipment damage and extending the equipment's service life. In addition, vibrations generated during equipment use are eliminated when transmitted to the foot pad 5, preventing the equipment from moving and collapsing, thus improving the safety of equipment use.

[0095] The waterproof speaker using Example 3 can buffer speaker vibration, buffer the impact force when the speaker is moved or placed, improve the speaker's service life, and enhance the speaker's safety during use.

[0096] The remaining structure and working principle of Example 3 are the same as those of Example 1.

[0097] Example 4:

[0098] Embodiment 4 of the present invention discloses a waterproofing process, such as... Figure 11 As shown, the following operation steps are included:

[0099] S1: A waterproof groove is formed on the box using an integrated molding process;

[0100] S2: A structure is formed on the back plate at a position corresponding to the waterproof groove, which is embedded in the waterproof groove;

[0101] Specifically, a waterproof groove 101 is provided at the contact position between the housing 1 and the back panel 2. The waterproof groove 101 is integrally formed with the housing 1. An installation part 21 is provided on the back panel 2 at the position corresponding to the waterproof groove 101. The installation part 21 is integrally formed with the back panel 2.

[0102] S3: Fill the waterproof groove with sealant;

[0103] Specifically, after the housing 1 and back panel 2 are assembled, the mounting part 21 is positioned in the waterproof groove 101, and an appropriate amount of sealant 3 is injected into the waterproof groove 101 to ensure that there is no problem of excessive or insufficient sealant 3 after the housing 1 and back panel 2 are installed.

[0104] S4: Install the back panel onto the housing, with the mounting portion embedded in the waterproof groove;

[0105] Specifically, the back plate 2 is installed onto the housing 1 under the guidance of the extension 212 on the mounting part 21. The mounting clip 211 of the mounting part 21 is embedded in the waterproof groove, so that the back plate 2 and the housing 1 form a closed structure. The molding structure 213 on the extension of the mounting clip 211, together with the waterproof groove 101, forms a prototype sealing structure, which can improve the sealing effect of the sealant 3.

[0106] S5: The sealant fills the gap between the mounting part and the waterproof groove.

[0107] The waterproofing process described in Example 4 has good waterproofing performance, and by injecting sealant 3, a sealed structure is formed after the box body 1 and the back panel 2 are assembled, which can save on sealing materials.

[0108] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
