Abstract
Description
Technical Field
[0001] This application relates to the field of loudspeaker technology, and in particular to a loudspeaker and electronic device. Background Technology
[0002] When communication terminals such as walkie-talkies and mobile phones are used in harsh environments such as rain or water immersion, liquid often gets inside. Although the devices themselves are IPX8 waterproof, preventing liquid from entering and damaging the equipment, if the speaker's front cavity is filled with liquid and cannot be drained in time, it will seriously affect the speaker's normal operation, causing low volume or almost no sound. It will only be possible to use the speaker normally after a considerable period of time to drain the liquid completely.
[0003] In existing technology, a drain outlet is typically created in the front cavity of the horn to allow the liquid inside to drain slowly under gravity. However, it still takes a considerable amount of time for the horn to completely empty the liquid from the front cavity. In emergency situations, abnormal sound from the equipment can have serious consequences. Utility Model Content

[0029] Please see Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a loudspeaker according to an embodiment of this application; Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the middle loudspeaker along section line I-I'; Figure 3 yes Figure 1 A schematic diagram of the exploded structure of a loudspeaker. The loudspeaker 1 provided in this application embodiment includes a housing 11, a speaker assembly 12, and a drainage assembly 13.
[0030] The speaker assembly 12 is disposed on the housing 11 for emitting audio, and the speaker assembly 12 and the housing 11 form a front cavity 111. The drain assembly 13 includes a first liquid suction member 131, which is disposed in the front cavity 111 for absorbing liquid in the front cavity 111.
[0031] Please continue reading. Figure 4 , Figure 4 This is a schematic diagram of a casing embodiment of the present application. The casing 11 is provided with a drain port 112, and a portion of the first liquid suction member 131 is disposed adjacent to the drain port 112. The drain port 112 is used to drain the liquid in the first liquid suction member 131.
[0032] The first liquid-absorbing element 131 can be made of foam, such as a sponge, which can form a capillary effect to absorb liquid. The first liquid-absorbing element 131 is disposed in the front cavity 111, absorbing and concentrating the liquid in the front cavity 111 into the first liquid-absorbing element 131. Since a portion of the first liquid-absorbing element 131 is adjacent to the drain port 112, the liquid absorbed by the first liquid-absorbing element 131 can be discharged through the drain port 112. This solves the problem in the prior art where the liquid in the front cavity can only be slowly discharged under the action of gravity, resulting in a slow discharge rate and affecting the operation of the equipment. This application improves the discharge rate of the liquid in the front cavity 111 of the speaker 1 by first concentrating the liquid in the front cavity onto the first liquid-absorbing element 131, and then allowing the liquid to be discharged from the drain port 112 under the influence of gravity on the first liquid-absorbing element 131.
[0033] It is understandable that the first liquid-absorbing element 131 can be made of other porous materials that are easy to absorb water and resistant to aging. This application does not limit the specific material selection of the first liquid-absorbing element 131.
[0034] Furthermore, due to the porous structure of the first liquid-absorbing element 131, it can also absorb some high-frequency sound, reduce the reflection of the front cavity 111, which helps to reduce high-frequency noise and improve the sound quality emitted by the speaker assembly 12.
[0035] In reality, the gravity acting on a liquid is equal to the product of its mass and gravitational acceleration. Therefore, when the amount of liquid in the front cavity 111 is small, the dispersed liquid will adhere to the surface of the speaker assembly 12. Since the mass of the dispersed liquid is small, the gravity acting on the liquid will also be small. Furthermore, due to the surface tension of the liquid, the liquid will continue to adhere to the surface of the speaker assembly 12 and cannot be discharged, thus failing to completely drain the liquid from the front cavity. In this embodiment, a first liquid-absorbing element 131 is provided in the front cavity 111 to absorb the liquid in the front cavity 111. The liquid in the front cavity 111 is first concentrated on the first liquid-absorbing element 131. At this time, the mass of the liquid increases, and the gravity on the liquid increases. This can accelerate the discharge of the liquid in the first liquid-absorbing element 131 from the drain port 112 under the action of gravity, thereby increasing the discharge rate of the liquid in the front cavity 111. When the front cavity 111 is immersed in liquid, the liquid in the front cavity 111 can be drained quickly, allowing the speaker 1 to quickly return to normal, improving the practicality of the speaker 1 and enhancing the user's experience with the speaker 1.
[0036] Optionally, the horn assembly 12 includes a horn 121, and a first liquid-absorbing member 131 is located between the horn 121 and the housing 11 and is disposed around the edge region of the horn 121.
[0037] Specifically, such as Figure 3As shown, the first liquid-absorbing member 131 can be annular. The first liquid-absorbing member 131 is located between the speaker 121 and the housing 11, and is arranged around the edge area of the speaker 121 to absorb the liquid that is difficult to drain from the edge area of the speaker 121. This achieves the goal of draining the liquid in the front cavity 111, preventing the speaker 121 from being affected by the attached liquid and thus failing to produce sound normally or producing too little sound or noise. This improves the sound quality of the speaker 1 and enhances the practicality of the speaker 1.
[0038] In another embodiment, the shape of the first liquid-absorbing member 131 may be set according to the shape of the edge region of the horn 121, and this application does not impose any specific limitations on this.
[0039] Optionally, the housing 11 is provided with a first buckle (not shown), and the first liquid-absorbing member 131 is provided with a second buckle (not shown). The housing 11 and the first liquid-absorbing member 131 can then be connected through the engagement of the first and second buckles to fix the first liquid-absorbing member 131. This prevents the first liquid-absorbing member 131 from deforming under the weight of the absorbed liquid and accumulating at the bottom of the front cavity 111, thus hindering its ability to absorb liquid adsorbed on the surface of the speaker assembly 12 and affecting drainage efficiency. Furthermore, the deformation and accumulation of the first liquid-absorbing member 131 may also compress the speaker assembly 12, affecting its sound output.
[0040] This application uses the cooperation of the first and second buckles to fix the first liquid suction member 131 to the housing 11, which can prevent the first liquid suction member 131 from deforming and improve the drainage efficiency of the first liquid suction member 131 for the liquid in the front cavity 111.
[0041] In one embodiment, the housing 11 may have an adhesive layer, and the first absorbent member 131 may be adhered to the housing 11 by the adhesive layer. In other embodiments, the first absorbent member 131 may be connected to the housing 11 by other means, and this application does not limit this.
[0042] Optionally, a groove is provided on the side of the housing 11 near the speaker 121, and the drain port 112 communicates with the groove. The first liquid-absorbing member 131 is disposed in the groove. The groove can thus fix the first liquid-absorbing member 131, preventing deformation of the first liquid-absorbing member 131 under the gravity of the absorbed liquid, which would affect the drainage efficiency. Furthermore, the communication between the groove and the drain port 112 ensures that the first liquid-absorbing member 131 is partially adjacent to the drain port 112, allowing the liquid in the first liquid-absorbing member 131 to be discharged from the drain port 112 under gravity. This improves the drainage efficiency of the drainage assembly 13 in the front cavity 111 and enhances the practicality of the speaker 1.
[0043] Optionally, the drain port 112 can be located at the bottom of the front cavity 111 along the direction of gravity of the speaker 1, so that the liquid in the first liquid suction member 131 can be smoothly discharged from the drain port 112 under the action of gravity, thereby quickly draining the liquid in the front cavity 111 and improving the practicality of the speaker 1.
[0044] Optionally, the drainage assembly 13 further includes a liquid suction mechanism 132, which is disposed on the housing 11 and located outside the front cavity 111. The liquid suction mechanism 132 is connected to the first liquid suction member 131 through the drainage port 112, and is used to suck up the liquid in the first liquid suction member 131. By connecting the liquid suction mechanism 132 to the first liquid suction member 131, the liquid in the first liquid suction member 131 will be sucked up by the liquid suction mechanism 132, that is, the liquid is discharged from the front cavity 111 to the outside of the front cavity 111.
[0045] In one embodiment, the liquid absorption mechanism 132 includes a second liquid absorption member 1321, which can also be foam, and the second liquid absorption member 1321 can be the same type of foam as the first liquid absorption member 131. The second liquid absorption member 1321 is disposed on the housing 11 and located outside the front cavity 111. The first liquid absorption member 131 and the second liquid absorption member 1321 are connected through a drain port 112, and the second liquid absorption member 1321 is used to absorb the liquid in the first liquid absorption member 131.
[0046] Since the second suction member 1321 is connected to the first suction member 131, the liquid in the first suction member 131 will diffuse through the drain port 112 onto the second suction member 1321 under the capillary action of the second suction member 1321. The second suction member 1321 will then absorb the liquid in the first suction member 131, thereby more quickly draining the liquid from the first suction member 131 into the front chamber 111. The liquid in the second suction member 1321 will then be discharged from its lower end under the influence of gravity.
[0047] In one embodiment, a guide groove may be provided on the surface of the housing 11, and the second liquid suction member 1321 is disposed in the guide groove. In this way, the guide groove can guide the discharge of liquid in the second liquid suction member 1321.
[0048] Understandably, during the process of draining the liquid from the front chamber 111, the first suction member 131 first draws the liquid from the front chamber 111 into itself, and then transfers the liquid to the second suction member 1321 through the drain port 112. After the second suction member 1321 draws the liquid from the first suction member 131, the liquid in the second suction member 1321 is discharged from the second suction member 1321 under the action of gravity. In this process, the first suction member 131 continuously draws the liquid from the front chamber 111 and transfers the liquid to the second suction member 1321, and the second suction member 1321 continuously absorbs the liquid from the first suction member 131 and discharges it until the liquid in the front chamber 111 is completely drained, thereby improving the drainage efficiency of the drain assembly 13.
[0049] Optionally, the liquid suction mechanism 132 further includes a pressing member 1322, which is disposed on the side of the second liquid suction member 1321 away from the housing 11. The pressing member 1322 can also be connected to the operating circuit (not shown) of the speaker assembly 12. When the pressing member 1322 is pressed, the pressing member 1322 controls the operating circuit and squeezes the second liquid suction member 1321 to discharge the liquid in the second liquid suction member 1321.
[0050] The pressing member 1322 can be a pressing plate corresponding to the size of the second liquid-absorbing member 1321 and a button connected to the pressing plate. After the second liquid-absorbing member 1321 absorbs the liquid in the first liquid-absorbing member 131, the user can apply force to the pressing member 1322 to squeeze the second liquid-absorbing member 1321. The pressing member 1322 squeezes the second liquid-absorbing member 1321, and the liquid in the second liquid-absorbing member 1321 is discharged from the second liquid-absorbing member 1321 under the squeezing action of the pressing member 1322, thereby increasing the rate at which the second liquid-absorbing member 1321 discharges liquid. Furthermore, the second liquid-absorbing member 1321 can continue to absorb the liquid in the first liquid-absorbing member 131 to increase the rate at which the liquid in the front cavity 111 is discharged.
[0051] Specifically, when there is liquid in the front cavity 111 that needs to be drained, the user can press the pressing member 1322 to drain the liquid in the second liquid suction member 1321, so that the second liquid suction member 1321 continuously absorbs the liquid in the first liquid suction member 131 and drains the liquid until the liquid in the front cavity 111 is drained, thereby further improving the draining rate of the liquid in the front cavity 111, improving the draining efficiency of the draining assembly 13, and enhancing the user's experience of using the speaker 1.
[0052] In practice, after the first suction member 131 has discharged most of the liquid, the remaining liquid in the first suction member 131 has a relatively small mass, meaning the gravity acting on the liquid in the first suction member 131 is relatively small. Therefore, the liquid discharge rate in the first suction member 131 is slow. If the suction mechanism 132 is not provided, it would still take a relatively long time to discharge the remaining liquid in the first suction member 131. Therefore, this embodiment, by providing a second suction member 1321 connected to the first suction member 131 and a pressing member 1322 that presses against the second suction member 1321, can achieve faster discharge of the remaining liquid in the first suction member 131, thus improving the drainage efficiency of the drainage assembly 13.
[0053] Meanwhile, since the pressing element 1322 is connected to the operating circuit of the speaker assembly 12, the operating circuit can be controlled by pressing the pressing element 1322. That is, when the user needs to control the operation of the speaker assembly 12, they can also press the pressing element 1322 to control the operating circuit, thereby controlling the operation of the speaker assembly 12, such as controlling the volume of sound emitted by the speaker assembly 12. At the same time, since the pressing element 1322 is pressed, it will also squeeze the second liquid suction element 1321, accelerating the drainage rate of the second liquid suction element 1321. That is, when the user controls the operation of the speaker assembly 12, the liquid can be drained unconsciously at the same time, further improving the user's experience of using the speaker 1.
[0054] Optionally, the liquid suction mechanism 132 may also include an elastic element (not shown), and the pressing element 1322 is connected to the housing 11 via the elastic element so that the pressing element 1322 can move relative to the housing 11.
[0055] The elastic element can be a spring or other component. The pressing element 1322 is connected to the housing 11 through the elastic element. When the user presses the pressing element 1322, the pressing element 1322 moves closer to the housing 11 and compresses the elastic element. When the user releases the pressing element 1322, the elastic element returns to its original length and pushes the pressing element 1322 away from the housing 11 so that the pressing element 1322 returns to its original position. The user does not need to manually return the pressing element 1322 to its original position, thus improving the user experience.
[0056] Optionally, the speaker assembly 12 also includes a dustproof mesh 122, which is detachably connected to the housing 11. The dustproof mesh 122, the housing 11, and the speaker 121 form a front cavity 111. The dustproof mesh 122 is used to isolate the speaker 121 from the outside world, preventing dust and other external particles from entering the front cavity 111 and adhering to the speaker 121, thus affecting the sound quality emitted by the speaker 121, improving the sound quality emitted by the speaker 1, and enhancing the practicality of the speaker 1.
[0057] In summary, this application improves the rate at which liquid is drained from the front cavity 111 by providing a first liquid-absorbing member 131 in the front cavity 111. Furthermore, by providing a liquid-absorbing mechanism 132 outside the front cavity 111 to absorb the liquid from the first liquid-absorbing member 131, the rate at which liquid is drained from the front cavity 111 is further improved, thereby enhancing the drainage efficiency and practicality of the drainage assembly 13 and improving the user experience of the speaker 1.
[0058] This application also provides an electronic device (not shown), including the speaker 1 as described above. The electronic device can be a walkie-talkie, mobile phone, or other communication terminal device. When the electronic device is exposed to harsh environments such as rain or water immersion, the user can operate the pressing member 1322 of the speaker 1 to expel liquid from the front cavity 111 of the speaker 1, ensuring the normal operation of the speaker 1 on the electronic device.
[0059] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
