Description

Technical Field

[0001] This utility model relates to headphones, and more particularly to a type of over-ear headphone and its connecting bracket. Background Technology

[0002] The headphones include a headband and earcups, as well as a connecting bracket that connects the headband and earcups. The connecting bracket has elastic tabs to allow users to adjust the position of the earcups and has shock absorption capabilities, which can make the earcups fit the user's ears stably and maintain a comfortable wearing experience.

[0003] Existing headphone connectors typically consist of two housings and the aforementioned elastic tab. During installation, the elastic tab is first secured to one of the housings using screws, and then the two housings are joined together and covered by screws. However, this method of securing the connector has the following drawbacks:

[0004] 1. One of the housings needs to have screw posts that connect with the elastic sheet and another housing. To ensure the strength of the mold, the two types of screw posts need to be spaced apart, which results in the housings occupying a large space.

[0005] 2. Because multiple screws are needed to fix the elastic sheet to the two shells respectively, the production costs such as parts and processes are increased, and the overall weight of the headphones is also increased. Utility Model Content

[0006] To address the issues of existing connecting brackets requiring a large space for the housing, increasing production costs, and adding to the overall weight of the headphones, the purpose of this invention is to propose a headphone and its connecting bracket that eliminates the need for screws to fix the elastic sheet.

[0007] The connecting bracket for headphones proposed by this utility model to solve the technical problem includes:

[0008] A first housing, which is provided with a first engaging structure;

[0009] An elastic sheet, integrally formed with a second engaging structure, engages with a first engaging structure of the first housing via the second engaging structure, thereby preventing the elastic sheet from moving relative to the first housing; and

[0010] A second housing, which is combined with the first housing and together clamps the elastic sheet.

[0011] The over-ear headphones proposed by this utility model to solve the technical problem include:

[0012] One end;

[0013] The two connecting brackets for the aforementioned over-ear headphones are characterized in that the two connecting brackets are respectively disposed at both ends of the headband; and Two ear cups, each mounted on one of the two connecting brackets.

[0014] This invention, by integrally forming the second engaging structure on the elastic sheet and engaging it with the first engaging structure of the first housing, prevents the first housing and the elastic sheet from moving relative to each other, thus achieving the following benefits:

[0015] 1. The first housing only needs to be provided with screw posts for fixing to the second housing, thereby reducing the space requirement of the first housing and facilitating the miniaturization of the headphone product.

[0016] 2. The first housing engages with the elastic piece without the need for screws, which reduces material costs, helps control production costs, and also reduces weight, making the headphones lighter.

[0017] 3. The elastic sheet does not require holes to be made for screw fixing to the first housing, thus reducing the need for hole design, avoiding weakening the structure of the elastic sheet, and giving the elastic sheet better structural strength.

[0018] 4. During the assembly process, after the first housing and the elastic sheet are assembled, the second housing can be directly combined with the first housing. The elastic sheet does not require screw fastening, which can save time and reduce costs. Attached Figure Description

Detailed Implementation

[0028] The accompanying drawings illustrate the technical solutions of this utility model in more detail. Throughout the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions. The described embodiments are only some, not all, of the embodiments of this utility model. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0029] like Figures 1 to 3 As shown, the preferred embodiment of the present invention provides a headphone connection bracket 80, which includes a first housing 10, an elastic sheet 20, and a second housing 30, as... Figure 4 As shown, the second housing 30 is combined with the first housing 10 and the elastic sheet 20 is sandwiched between the two.

[0030] Among them, such as Figure 2 As shown, the first housing 10 has a first engaging structure, and the elastic piece 20 has a second engaging structure 21. The elastic piece 20 can engage with the first engaging structure of the first housing 10 through the second engaging structure 21, so that the elastic piece 20 cannot move relative to the first housing 10. Thus, the elastic piece 20 and the first housing 10 do not need to be fixed with screws, which helps to optimize the production process and reduce costs.

[0031] The first housing 10 is made of plastic components and can be injection molded to form the required shape and the first engaging structure. The elastic sheet 20 is integrally formed with the second engaging structure 21, that is, the second engaging structure 21 is formed when the elastic sheet 20 is manufactured.

[0032] In a preferred embodiment of the present invention, the elastic sheet 20 is a stamped metal sheet. A mold can be designed according to the shape of the elastic sheet 20 and its second engaging structure 21. Thus, the second engaging structure 21 can be formed at the same time as the elastic sheet 20 is stamped and formed through the mold.

[0033] like Figure 2 As shown, the second housing 30 is provided with two fixing holes 31, each of which allows a screw to pass through. By passing the screw through the fixing hole 31 and locking it to the first housing 10, the first housing 10 and the second housing 30 can be combined. Figure 4 As shown, and as previously described, the elastic sheet 20 is clamped between the second housing 30 and the first housing 10.

[0034] like Figure 5 As shown, in the connection bracket 80 of the headset of this utility model, during assembly, the elastic piece 20 is first combined with the first housing 10, and the second engaging structure 21 engages with the first engaging structure of the first housing 10, so that the elastic piece 20 cannot move relative to the first housing 10, thus preventing the elastic piece 20 from deviating from the installation position.

[0035] Then, by inserting screw 40 through the fixing hole 31 of the second housing 30 and locking it onto the first housing 10, the second housing 30 and the first housing 10 can be joined along a joining direction D, and the elastic piece 20 is clamped between the two, thus completing the assembly of the connecting bracket 80.

[0036] Compared to existing connecting brackets that use screws to connect the elastic sheet and the housing, this utility model integrally forms the second engaging structure 21 on the elastic sheet 20, which engages with the first engaging structure of the first housing 10, preventing the first housing 10 and the elastic sheet 20 from moving relative to each other. The first housing 10 only needs to be provided with screw posts for engaging with the second housing 30, which can reduce the space requirements of the first housing 10 and facilitate the miniaturization of headphone products.

[0037] Furthermore, the first housing 10 and the elastic piece 20 are fastened together without the need for screws, which saves on the material cost of purchasing screws and helps control the overall production cost of the headphones. Reducing the weight of screws also makes the headphones lighter, increasing the incentive for consumers to purchase them. At the same time, the elastic piece 20 does not need to be drilled with holes to be fixed to the first housing 10 with screws. The design of the elastic piece 20 can reduce the number of holes and retain better structural strength.

[0038] During assembly, the second engaging structure 21 is engaged with the first engaging structure of the first housing 10. After the first housing 10 and the elastic piece 20 are assembled, the first housing 10 and the second housing 30 can be directly connected without the need for screw fastening to fix the first housing 10 and the elastic piece 20, which can save time and reduce costs.

[0039] like Figure 2 and Figure 6 As shown, in a preferred embodiment of the present invention, the first engaging structure of the first housing 10 specifically includes two screw posts 12, and the second engaging structure 21 of the elastic sheet 20 includes two limiting holes 22. Each limiting hole 22 is matched and engaged with one of the corresponding screw posts 12. The two screw posts 12 are respectively aligned with the two fixing holes 31 of the second housing 30. After the screw passes through the fixing hole 31, it is locked to the screw post 12.

[0040] By matching and engaging the screw post 12 with the limiting hole 22, and locking the second housing 30 with a screw, the functions of engaging the elastic piece 20 and engaging the second housing 30 can be integrated simultaneously, which is beneficial to the simplified design of the structure. The matching and engaging mentioned above means that the diameter of the limiting hole 22 is approximately the same as the outer diameter of the screw post 12. When engaged, the elastic piece 20 cannot move freely, but a margin can be left to facilitate the engagement of the screw post 12 into the limiting hole 22, avoiding assembly difficulties.

[0041] In other embodiments, a single screw post 12 can be used in conjunction with a single limiting hole 22. The number of screw posts 12 and limiting holes 22 can be determined according to the fixing strength of the first housing 10 and the second housing 30 or other requirements. In the preferred embodiment of this utility model, two sets of screw posts 12 and limiting holes 22 are used, which can have a certain strength, not occupy too much space, and can prevent the limiting holes 22 from rotating around the screw posts 12.

[0042] like Figure 2 and Figure 6 As shown, the first engaging structure of the first housing 10 also includes a positioning protrusion 14 and a positioning notch 17. The positioning notch 17 is formed on the top of the first housing 10, and the positioning protrusion 14 is formed in the middle of the positioning notch 17. The second engaging structure 21 of the elastic piece 20 includes two positioning feet 202. The two positioning feet 202 extend from a body 201 of the elastic piece 20 at intervals, and a positioning recess 24 is formed between the two positioning feet 202 and the body 201.

[0043] like Figure 6As shown, when assembling the first housing 10 and the elastic piece 20, the end of the body 201 of the elastic piece 20 is engaged in the positioning notch 17 of the first housing 10, and the positioning protrusion 14 located in the middle of the positioning notch 17 is engaged in the positioning recess 24 between the two positioning feet 202. The positioning notch 17 and the positioning protrusion 14 hold the elastic piece 20 so that it cannot move relative to the first housing 10.

[0044] like Figure 2 and Figure 4 As shown, the first engaging structure of the first housing 10 further includes two positioning holes 13, and the second engaging structure 21 of the elastic piece 20 includes two positioning inserts 23. The two positioning holes 13 extend along a first direction D1 perpendicular to the engagement direction D. The two positioning inserts 23 are respectively inserted into the two positioning holes 13, which can roughly position the elastic piece 20 and ensure that the elastic piece 20 is indeed clamped between the second housing 30 and the first housing 10 when they are engaged.

[0045] like Figure 5 As shown, the limiting hole 22 is matched with the screw post 12 along the engagement direction D, and the positioning insert 23 is inserted into the positioning hole 13 along the first direction D1. The screw post 12 is located on the side of the positioning hole 13 in the first direction D1. Specifically, during assembly, the positioning insert 23 is first inserted into the positioning hole 13 at an inclined angle, and the positioning insert 23 can move in the positioning hole 13, so that the elastic piece 20 can swing relative to the first housing 10 in the engagement direction D, thereby driving the limiting hole 22 to match and engage with the screw post 12.

[0046] By using the positioning holes 13, which are spaced apart from the screw post 12 and whose assembly directions are staggered, to cooperate with the positioning insert 23, the strength and stability of the assembly can be improved, and the limiting hole 22 can be prevented from deflecting around the screw post 12 after it is matched and engaged with the screw post 12. In addition, after the elastic piece 20 swings in the engagement direction D, the second engaging structure 21 can be engaged in the positioning notch 17 and the positioning protrusion 14 can be engaged between the two positioning feet 202.

[0047] In addition, such as Figure 2 and Figure 4As shown, in a preferred embodiment of the present invention, the first housing 10 is provided with a base 100 at the bottom. When the second housing 30 is combined with the first housing 10 along the combination direction D, the second housing 30 abuts against the base 100 along the first direction D1, which can provide an alignment effect. The two positioning holes 13 are formed on the base 100, and the two positioning inserts 23 are respectively formed by protruding from the two positioning feet 202. After the elastic piece 20 swings in the combination direction D, the two positioning feet 202 abut against the base 100 along the first direction D1, which can cooperate with the first locking structure to restrict the movement of the elastic piece 20.

[0048] like Figure 2 and Figure 6 As shown, the first engaging structure of the first housing 10 also includes two protruding rib structures. The two protruding rib structures are spaced apart on a second direction D2 that intersects both the first direction D1 and the engagement direction D. Each of the protruding rib structures includes a first protruding rib 15 and a second protruding rib 16. The second engaging structure 21 of the elastic piece 20 is engaged between the first protruding ribs 15 of the two protruding rib structures, specifically by the two positioning feet 202. In this way, the movement of the elastic piece 20 can be restricted in the second direction D2.

[0049] like Figure 6 As shown, the first rib 15 and the second rib 16 of each rib structure are spaced apart in the first direction D1. The second engaging structure 21 of the elastic sheet 20 is partially engaged between the first rib 15 and the second rib 16 of each rib structure. Specifically, a portion of each positioning foot 202 is engaged between the first rib 15 and the second rib 16 of one of the rib structures, thereby restricting the movement of the elastic sheet 20 in the first direction D1.

[0050] The second engaging structure 21 also includes two notches 25, which are recessed on opposite sides of the elastic sheet 20 in the second direction D2. The first ribs 15 of the two rib structures extend into the two notches 25. Specifically, the two notches 25 are formed on the two positioning feet 202.

[0051] In other embodiments, the second engaging structure 21 may not have a notch 25 and may extend directly between the first ribs 15 of the two rib structures. Similarly, it can restrict the movement of the elastic piece 20 in the second direction D2. However, in the preferred embodiment of the present invention, the notch 25 is used to cooperate with the first rib 15, which can restrict the movement of the elastic piece 20 in the first direction D1, and the aforementioned second engaging structure 21 can satisfy the structure of partially engaging the first rib 15 and the second rib 16.

[0052] In a preferred embodiment of the present invention, as the aforementioned elastic sheet 20 swings in the engagement direction D, the second engaging structure 21 can also be engaged between the first protruding rib 15 of the two protruding rib structures, and partially engaged between the first protruding rib 15 and the second protruding rib 16; in addition, the engagement direction D, the first direction D1 and the second direction D2 are perpendicular to each other.

[0053] In a preferred embodiment of the present invention, the first engaging structure and the second engaging structure 21 have multiple engaging designs with different engaging methods and directions, which can provide excellent assembly stability. In other embodiments, at least one of the above-mentioned multiple engaging designs can be selected, as long as the elastic piece 20 can be restricted to the first housing 10 during assembly. The actual form of the first engaging structure and the second engaging structure 21 is not limited to the preferred embodiment of the present invention.

[0054] like Figure 7 As shown, a preferred embodiment of the present invention provides a headset, which includes two of the aforementioned connecting brackets 80, a headband 91 and two earcups 92. The two connecting brackets 80 are respectively disposed at both ends of the headband 91, and the two earcups 92 are respectively disposed on the two connecting brackets 80. The two connecting brackets 80 are connected to the headband 91, and can conform to the user's ears by the elastic deformation of the elastic sheet 20.

[0055] Through each of the connecting brackets 80, the elastic sheet 20 is integrally formed with the second engaging structure 21 to cooperate with the first engaging structure of the first housing 10. The headphones can also have the aforementioned benefits of the connecting brackets 80, such as miniaturization, weight reduction, and control of production costs.

[0056] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical solution provided by the present utility model shall still fall within the scope of the technical solution of the present utility model.
