Description

Technical Field

[0001] This utility model relates to the field of headphone sound outlets, specifically a sound outlet with a detachable filter and shock absorption. Background Technology

[0002] The sound outlet, also known as the sound tube or nozzle, is the channel at the front of the earphone that transmits sound to the ear canal. It is commonly found in in-ear or semi-in-ear earphones. It is usually located at the head of the earbud, in direct contact with the ear canal, and is mostly cylindrical or conical in shape.

[0003] The sound outlet can effectively guide sound waves into the ear canal, reducing sound loss and thus ensuring the quality of the sound entering the ear through the headphones.

[0004] Since the sound outlet is usually located on semi-in-ear and in-ear headphones, it is often necessary to take them out and put them down frequently. Moreover, as the size of semi-in-ear and in-ear headphones in current technology is gradually decreasing, the headphones are more likely to fall off when being taken out and put down. If the headphones fall off, they will be damaged. The sound outlet part is prone to damage due to the large shear stress when it falls because of the neck structure.

[0005] In addition, the sound outlet is also the main channel for foreign objects and dust to enter the headphones, so how to prevent dust from entering without affecting the sound quality of the headphones is an urgent problem to be solved. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing technologies that cannot keep the sound outlet effectively dustproof for a long time. It provides a sound outlet with a detachable filter and shock absorption. The detachable filter accessory on the sound outlet allows the sound outlet to maintain a transparent and dustproof effect for a long time, thereby maintaining dust protection for the headphones without affecting the sound output.

[0007] The objective of this utility model is mainly achieved through the following technical solutions:

[0008] A detachable filter damping sound outlet includes a straight section body, one end of which is fixed with a connecting end for connecting to an earphone, and the other end of which is fixed with a stabilizing section, the stabilizing section having a sound outlet at the end opposite to the straight section body;

[0009] The sound outlet is equipped with a detachable filter accessory that can cover the sound outlet, and the detachable filter accessory is detachably and fixedly connected to the stabilizing section.

[0010] Furthermore, the straight section body is provided with a plurality of annular ribs, which are evenly distributed longitudinally along the axis of the straight section body.

[0011] Each of the annular ribs is fixed with several buffer echo plates, which are distributed circumferentially around the axis of the annular rib.

[0012] Furthermore, the annular rib includes a fixed ring body, which is fixed to the straight section body. A slope is provided below the fixed ring body, the top of the slope is fixed to the fixed ring body, and the bottom of the slope is fixed to the inner wall of the straight section body.

[0013] Furthermore, the buffer echo plate bends and extends from the annular rib toward the sound outlet.

[0014] Furthermore, the detachable filter accessory includes a mounting ring, the mounting ring having a central hole that can completely cover the sound outlet;

[0015] A fixed filter screen is provided inside the central hole, and the fixed filter screen is fixedly connected to the mounting ring.

[0016] The edge of the mounting ring is provided with several embedded connection components, and the side of the stabilizing section is fixed with a connection end that is detachably and fixedly connected to the embedded connection components.

[0017] Furthermore, the connecting end includes a connecting ring, which has a plurality of fixing grooves, each of which has a plurality of longitudinally distributed embedding grooves, and the embedding connecting component is inserted into the fixing groove and fitted into the embedding groove.

[0018] Furthermore, the embedded connection assembly includes a connecting post, one end of which is inserted into the fixing groove, and the other end of which is embedded in the mounting ring and fixed to the mounting ring.

[0019] Furthermore, a plurality of elastic barbs are provided at one end of the connecting post inserted into the fixing groove. The position and number of the elastic barbs correspond to the position and number of the embedding groove: each elastic barb corresponds to one embedding groove, and the elastic barb can be embedded in the embedding groove.

[0020] Furthermore, a plurality of side embedding blocks are fixed at one end of the connecting post that is embedded in the mounting ring. The side embedding blocks are embedded in the mounting ring and extend away from the axis of the connecting post.

[0021] In summary, this utility model has the following advantages compared with the prior art:

[0022] This invention reinforces the connection between the sound outlet and the earphone by combining the end-end design, thereby avoiding the risk of damage to the sound outlet to a certain extent. The straight section of the main body effectively transmits sound waves, transmitting sound into the human ear canal at the sound outlet. The increased wall thickness of the stabilizing section effectively maintains the stability of sound wave transmission by keeping the sound outlet stable.

[0023] Based on this, in order to protect the sound outlet from impurities, a detachable filter is installed at the sound outlet. The detachable filter is detachably fixed to the stabilizing section, which allows the detachable filter to be effectively disassembled and replaced, thereby avoiding the risk of earwax, dust and other foreign objects clogging the detachable filter.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0031] Example:

[0032] like Figures 1-4As shown, this embodiment relates to a filter-detachable shock-absorbing sound outlet, including a straight section body 3. One end of the straight section body 3 is fixed with a connecting end 4, which is used to connect to an earphone. The other end of the straight section body 3 is fixed with a stabilizing section 2. The stabilizing section 2 has a sound outlet 1 at the end facing away from the straight section body 3.

[0033] The sound outlet 1 is provided with a detachable filter accessory 7 that can cover the sound outlet 1, and the detachable filter accessory 7 is detachably and fixedly connected to the stabilizing section 2.

[0034] Currently, in daily use, the sound outlet of headphones needs to extend outward and work with earplugs and other structures to smoothly guide sound waves into the user's ear canal in order to provide a high-quality sound transmission channel. On this basis, due to its extended and relatively independent structure, the sound outlet is at risk of damage due to shear stress when subjected to external forces.

[0035] Furthermore, because it is directly connected to an external source, impurities can easily enter the sound outlet, leading to damage to the headphones.

[0036] In this embodiment, by combining the setting of end 4, the connection position between the sound outlet and the earphone is reinforced at the end, thereby avoiding the risk of damage to the sound outlet to a certain extent. The sound waves are effectively transmitted through the straight section body 3, and the sound is transmitted into the human ear canal at the sound outlet 1. The stabilizing section 2, by increasing the wall thickness, can effectively maintain the stability of sound wave transmission by keeping the sound outlet stable.

[0037] Based on this, in order to protect the mouthpiece from impurities, a detachable filter accessory 7 is provided at the mouthpiece 1. The detachable filter accessory 7 and the stabilizing section 2 are detachably fixedly connected, so that the detachable filter accessory 7 can be effectively disassembled and replaced, thereby avoiding the risk of earwax, dust and other foreign objects clogging the detachable filter accessory 7.

[0038] Furthermore, the straight section body 3 is provided with a plurality of annular ribs 6, which are evenly distributed longitudinally along the axis of the straight section body 3.

[0039] Each of the annular ribs 6 is fixed with a plurality of buffer echo plates 5, which are distributed circumferentially around the axis of the annular rib 6.

[0040] In this embodiment, the annular rib 6 inside the straight section body 3 can effectively limit the reflection of sound waves by protruding part inside the straight section body 3, thereby achieving a certain filtering effect and improving the sound quality at the sound outlet 1. In this embodiment, the setting of the buffer echo arc plate 5 can effectively guide the sound waves, thereby avoiding the problem of sound waves propagating backward after passing through the straight section body 3, and ensuring the sound quality at the sound outlet 1 to a certain extent.

[0041] The buffer echo arc plate 5 can also provide elastic buffering capacity for the sound outlet by being made of elastic material, so as to play a buffering role when the sound outlet is subjected to external force impact, thereby reducing the damage to the sound outlet.

[0042] Furthermore, the annular rib 6 includes a fixed ring body 61, which is fixed to the straight section body 3. A slope 62 is provided below the fixed ring body 61. The top of the slope 62 is fixed to the fixed ring body 61, and the bottom of the slope 62 is fixed to the inner wall of the straight section body 3.

[0043] In this embodiment, the slope 62 on the fixed ring 61 guides the sound waves, thereby further improving the overall quality of the sound transmitted to the sound outlet 1.

[0044] Furthermore, the buffer echo plate 5 bends and extends from the annular rib 6 toward the sound outlet 1.

[0045] The buffer echo arc plate 5, through its own bending and extension, can effectively enhance the guiding performance of sound waves and the echo enhancement capability, thereby further improving the overall sound quality at the sound outlet 1.

[0046] Furthermore, the detachable filter accessory 7 includes a mounting ring 75, the mounting ring 75 having a central hole 73 at its center, the central hole 73 being able to completely cover the sound outlet 1;

[0047] A fixed filter 74 is provided in the central hole 73, and the fixed filter 74 is fixedly connected to the mounting ring 75.

[0048] The edge of the mounting ring 75 is provided with a plurality of embedded connecting components 72, and the side of the stabilizing section 2 is fixed with a connecting end 71 that is detachably and fixedly connected to the embedded connecting components 72.

[0049] In this embodiment, the mounting ring 75 covers the stabilizing section 2 so that the central hole 73 can completely cover the sound outlet 1, thereby effectively increasing the coverage area of ​​the fixed filter 74 and preventing sound from being blocked.

[0050] The edge of the mounting ring 75 is detachably and fixedly connected to the side of the stabilizing segment 2 via several embedded connecting components 72. This allows the fixed filter 74 to be removed by disassembling the mounting ring 75, or the fixed filter 74 to be replaced by replacing the mounting ring 75. Both replacement and cleaning of the fixed filter 74 are very convenient. This improves the ease of replacement of the detachable filter accessory 7 in this embodiment.

[0051] Furthermore, the connecting end 71 includes a connecting ring 711, which has a plurality of fixing grooves 712. Each fixing groove 712 has a plurality of longitudinally distributed embedding grooves 713. The embedding connecting component 72 is inserted into the fixing groove 712 and fits into the embedding groove 713.

[0052] In this embodiment, the connecting ring 711 serves as the base for supporting the detachable filter accessory 7 and the connecting end 71. The fixing groove 712 within the connecting ring 711 is used for insertion with the embedded connecting component 72. Based on this insertion, the embedded connecting component 72 enhances the stability of the connection between the connecting end 71 and the embedded connecting component 72 by engaging with several embedding grooves 713. The portion of the embedded connecting component 72 embedded in the embedding grooves 713 is made of elastic material, thereby enabling the embedded connecting component 72 to be effectively pulled out from the fixing grooves 712 and the embedding grooves 713 under external force.

[0053] Furthermore, the embedded connection component 72 includes a connecting post 721, one end of which is inserted into the fixing groove 712, and the other end is embedded in the mounting ring 75 and fixed to the mounting ring 75.

[0054] In this embodiment, the connecting post 721 is inserted into the fixing groove 712, and a detachable fixed connection is formed between the mounting ring 75 and the connecting end 71 by embedding and fixing the mounting ring 75.

[0055] Furthermore, a plurality of elastic barbs 714 are provided at one end of the connecting post 721 that is inserted into the fixing groove 712. The position and number of the elastic barbs 714 correspond to the position and number of the embedding grooves 713: each elastic barb 714 corresponds to one embedding groove 713, and the elastic barb 714 can be embedded in the embedding groove 713.

[0056] In this embodiment, after the connecting post 721 is inserted into the fixing groove 712, the elastic barb 714 can be embedded in the embedding groove 713 and prevent the connecting post 721 from coming out of the fixing groove 712 through the interlocking relationship. However, if an external force pulls the mounting ring 75 away from the connecting end 71, the connecting post 721 will cause the elastic barb 714 to be pulled out of the fixing groove 712. At this time, the elastic barb 714 deforms under the action of the external force and can come out of the embedding groove 713 under sufficient external force. At the same time, the connecting post 721 can also be effectively pulled out of the fixing groove 712, thereby achieving the purpose of disassembling the mounting ring 75 from the connecting end 71.

[0057] Under the action of the elastic barb 714, the connecting post 721 cannot easily disengage from the fixing groove 712. However, when it is necessary to disassemble the mounting ring 75, the elastic barb 714 can be pulled out of the embedded groove 713 by external force, and the connecting post 721 can be disengaged from the fixing groove 712, thereby separating the mounting ring 75 and the connecting end 71.

[0058] Furthermore, a plurality of side embedding blocks 721 are fixed at one end of the connecting post 721 embedded in the mounting ring 75. The side embedding blocks 721 are embedded in the mounting ring 75 and extend in a direction away from the axis of the connecting post 721.

[0059] If the connecting post 721 and the mounting ring 75 are integrally formed, the stress point of the connecting post 721 and the mounting ring 75 is on the surface of the mounting ring 75, which makes it easy for local damage to occur when the connecting post 721 is inserted or removed.

[0060] In this embodiment, by embedding the connecting post 721 into the mounting ring 75, the connection point is embedded in the mounting ring 75. This ensures that when the connecting post 721 is inserted or removed, the force-bearing point of the connecting post 721 and the mounting ring 75 is located within the mounting ring 75. This allows more force to be distributed across the overall force of the mounting ring 75, reducing the risk of localized damage.

[0061] This embodiment distributes the external force on the connecting post 721 more widely into the mounting ring 75 by setting a side embedding block 721 at the end of the connecting post 721, thereby enhancing the stability of the connection between the mounting ring 75 and the connecting end 71 and further reducing the risk of local damage.

[0062] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
