Description

Technical Field

[0001] This utility model relates to the field of protective cover technology, specifically to an audio head protective cover. Background Technology

[0002] An audio connector, also known as an audio plug, is a component in audio equipment primarily used for connecting or transmitting audio signals. Common audio connectors include 3.5mm audio plugs, RCA plugs, and XLR plugs. These audio connectors are widely used for connecting devices such as headphones, speakers, microphones, audio equipment, computers, and televisions.

[0003] Currently, to improve the conductivity of audio connectors, reduce resistance during signal transmission, and ensure the quality of audio signal delivery, a metal plating is usually applied to the surface of the audio connector. However, audio devices are rarely in operation for extended periods in daily life, causing the metal plating on the audio connector to oxidize due to prolonged contact with air. This can lead to poor contact and other connection problems during subsequent use, affecting the normal operation of the audio connector. Utility Model Content

[0004] This utility model proposes an audio head protective cover, which serves to protect the audio head and solves the problem in related technologies where the audio head is prone to oxidation due to prolonged contact with air.

[0005] The technical solution of this utility model is as follows:

[0006] An audio head protective cover includes a cover body for fitting an external audio head. The cover body includes an inner cover body and an outer cover body. The outer cover body has a protective inner cavity and a first connection opening for connecting the protective inner cavity and the outside of the outer cover body. The inner cover body is located in the protective inner cavity, and a second connection opening is provided at one end of the inner cover body close to the first connection opening.

[0007] The sleeve is made of an elastic material.

[0008] Furthermore, the outer sleeve is made of plastic material, and the inner sleeve is made of elastomer material.

[0009] Furthermore, the protective inner cavity includes a fixing part and a mating part. The mating part is located between the fixing part and the first connecting opening. The width of the projection surface of the fixing part on the vertical horizontal plane is greater than the width of the projection surface of the mating part on the vertical horizontal plane. The inner sleeve is slidably connected to the protective inner cavity.

[0010] Furthermore, the inner sleeve has an abutment post at the end away from the second connection opening, and the abutment post is integrally formed with the inner sleeve.

[0011] Furthermore, the longitudinal section of the outer casing is an inverted "U" shape.

[0012] Furthermore, the outer casing is provided with a connecting ring.

[0013] Furthermore, the outer casing is provided with a connecting hole for connecting a connecting ring, the connecting ring being a double stainless steel ring.

[0014] The working principle and beneficial effects of this utility model are as follows:

[0015] The protective sleeve (sleeve body) used to cooperate with the external audio head in this utility model mainly includes an inner sleeve body and an outer sleeve body. The outer sleeve body is provided with a protective inner cavity. In order to allow the external audio head to enter the protective inner cavity, the outer sleeve body is also provided with a first connection opening.

[0016] The inner sleeve is located in the protective cavity, and in order to enable the inner sleeve to also cooperate with the audio head that enters the protective cavity, the inner sleeve is provided with a second connection opening.

[0017] Meanwhile, the sleeve in this utility model is made of elastic material, that is, both the outer sleeve and the inner sleeve are made of elastic material. In this way, even if the opening diameter of the first connecting opening and the second connecting opening is smaller than the diameter of the audio head, the outer sleeve and the inner sleeve can deform during the contact with the audio head, thereby ensuring that the audio head can enter the protective cavity and the interior of the inner sleeve. This makes this utility model not only protect audio heads of a certain size, but also greatly expands the scope of application of this utility model.

[0018] Furthermore, during the engagement of the audio head with the protective sleeve, both the inner and outer sleeves deform sequentially. Due to the elasticity of the material, the inner sleeve exerts a certain reaction force on the audio head, allowing it to be fixed to the audio head through mutual friction and compression. Similarly, the outer sleeve also exerts a certain reaction force on the inner sleeve, thus fixing the inner and outer sleeves to each other. This achieves multiple protections for the audio head located within the sleeve, effectively ensuring the sleeve's protective effect on the audio head and its stable fixation to the audio head without external force intervention. This effectively prevents the audio head from oxidizing due to prolonged contact with outside air. Attached Figure Description

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figure 1 , Figures 5-6 As shown, this embodiment proposes an audio head protective cover, which mainly includes a cover body 1 for cooperating with an external audio head. That is, by adding this embodiment to an audio device that is not in operation, the audio head of the audio device is covered and protected by this embodiment, which prevents the audio head from contacting the outside air and prevents the audio head from oxidizing due to prolonged contact with the air.

[0030] Specifically, such as Figure 2As shown, the sleeve 1 in this embodiment mainly includes an inner sleeve 11 and an outer sleeve 12. The outer sleeve 12 is provided with a protective inner cavity 121 and a first connecting opening 122 for connecting the protective inner cavity 121 and the outside of the outer sleeve 12. That is, the external audio head can enter the protective inner cavity 121 through the first connecting opening 122, so that the outer sleeve 12 can protect the audio head. The inner sleeve 11 is located in the protective inner cavity 121, and the end of the inner sleeve 11 close to the first connecting opening 122 is provided with a second connecting opening 111. That is, the external audio head entering the protective inner cavity 121 can also enter the interior of the inner sleeve 11 through the second connecting opening 111. The inner sleeve 11 and the outer sleeve 12 achieve multiple protection effects for the audio head.

[0031] The sleeve 1 is made of elastic material, that is, both the outer sleeve 12 and the inner sleeve 11 are made of elastic material. In this way, even if the opening diameter of the first connecting opening 122 and the second connecting opening 111 is smaller than the diameter of the audio head, the outer sleeve 12 and the inner sleeve 11 can deform during contact with the audio head, thereby ensuring that the audio head can enter the protective cavity 121 and the inner sleeve 11. This makes this embodiment not only protect audio heads of a certain size, but also greatly expands the scope of application of this embodiment.

[0032] In detail, by utilizing the material properties of the elastic material, the first connecting opening 122 deforms when the audio head is inserted into the outer casing 12, ensuring that the audio head can enter the interior of the outer casing 12; and the inner sleeve 11 located in the outer casing 12 deforms after being inserted by the external audio head, and can abut against the inner wall (protective inner cavity 121) of the outer casing 12, fixing the sleeve 1 to the audio head, thereby preventing the sleeve 1 from shaking or swaying on the audio head, which would affect the stability of the sleeve 1 on the audio head.

[0033] Furthermore, the sleeve 1, which deforms due to the insertion of the audio head, will, under the elastic properties of the elastic material, squeeze the audio head in turn (the outer sleeve 12 squeezes the inner sleeve 11, and the inner sleeve 11 squeezes the audio head), thereby increasing the friction between the audio head and the sleeve 1, thus ensuring the connection stability between the sleeve 1 and the audio head, making it difficult for this embodiment to detach from the audio head, and further ensuring the stability of this embodiment in use.

[0034] Meanwhile, considering that the inner sleeve 11 and the outer sleeve 12 in this embodiment have different working environments, the elastic materials constituting the outer sleeve 12 and the inner sleeve 11 should also be different. Preferably, the outer sleeve 12 is made of elastic materials with good wear resistance and hard texture, such as plastic materials, to avoid wear and tear during daily use; the inner sleeve 11 is made of elastic materials such as silicone, taking advantage of the high elasticity and soft texture of the elastic materials so that the inner sleeve 11 deforms when it comes into contact with the audio head, thereby better adapting to the audio head.

[0035] like Figures 3-4 As shown, the protective cavity 121 in this embodiment includes a fixing part 1211 and a mating part 1212. The mating part 1212 is located between the fixing part 1211 and the first connecting opening 122. The width of the projection surface of the fixing part 1211 on the vertical horizontal plane is greater than the width of the projection surface of the mating part 1212 on the vertical horizontal plane. The inner sleeve 11 is slidably connected in the protective cavity 121 so that the inner sleeve 11 moves into the fixing part 1211 under force during the engagement with the audio head. At this time, since the end of the inner sleeve 11 away from the audio head abuts against the protective cavity 121, it cannot move further back (deeper into the protective cavity 121), thereby allowing the audio head to be gradually inserted into the inner sleeve 11. Since the inner sleeve 11 deforms after engaging with the audio head, when the diameter of the deformed inner sleeve 11 is greater than or equal to the width of the projection surface of the fixing part 1211 on the vertical horizontal plane, the inner sleeve 11 will be stuck on the boundary line between the fixing part 1211 and the engaging part 1212. That is, the protective inner cavity 121 is provided with a limiting step for restricting the inner sleeve 11. By restricting the movement of the inner sleeve 11 in the protective inner cavity 121 (movement along the axial direction of the first connecting opening 122), the inner sleeve 11 is prevented from detaching from the outer sleeve 12 when the operator separates this embodiment from the audio head, thus effectively ensuring the integrity and stability of the overall structure of this embodiment.

[0036] The inner sleeve 11 has an abutment post 112 at the end away from the second connection opening 111. The abutment post 112 is integrally formed with the inner sleeve 11, that is, the abutment post 112 is also made of elastic material. When the abutment post 112 (the end of the inner sleeve 11 away from the audio head) abuts against the protective inner cavity 121, the abutment post 112 will deform and accumulate elastic potential energy. When the inner sleeve 11 loses the force clamping it, the abutment post 112 will begin to reset. This allows the abutment post 112 and the limiting step to cooperate with each other to clamp the inner sleeve 11, further improving the positional stability of the inner sleeve 11 inside the outer sleeve 12.

[0037] The longitudinal section of the outer casing 12 is an inverted "U" shape, meaning that the outer casing 12 can utilize the large moment of inertia of the "U" shaped cross section, making it more robust than traditional flat plate structures when subjected to bending forces. Due to the vertical walls on both sides, the structure can better distribute pressure when subjected to external forces, thereby reducing deformation and enabling the outer casing 12 to better provide protection.

[0038] The outer casing 12 is provided with a connecting ring 2. The presence of the connecting ring 2 allows this embodiment to work with keys that people use in daily life and that people pay attention to at all times, or to be hung directly on a backpack, reducing the probability of this embodiment being lost.

[0039] The outer casing 12 is provided with a connecting hole 123 for connecting the connecting ring 2. The connecting ring 2 is a double ring of stainless steel. Utilizing the deformable characteristics of the double ring of stainless steel, the connection between the connecting ring 2 and the outer casing 12 is detachable, so that users can replace the connecting ring 2 of different diameters according to different needs, thereby improving the flexibility of use of this embodiment.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
