Obviously, the embodiments described below 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 skilled in the art without creative effort are within the scope of protection of this utility model.
[0035] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.
[0036] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.
[0037] The following is in conjunction with the appendix Figure 1-7 The technical solution of this utility model will be further illustrated through specific implementation methods.
[0038] Example 1:
[0039] Please refer to Figure 1 and Figure 2 This utility model embodiment provides a headphone functional unit, which is applied in an ear clip-on headphone. Specifically, it includes a housing 1 and a main board 2. The housing 1 has an internal accommodating cavity, and the main board 2 is located in the accommodating cavity and installed inside the housing 1. The main board 2 is a PCB board, which provides mounting positions for various electronic components. The types of electronic components include, but are not limited to, an in-ear detection element 4, a battery 3, an antenna 5, etc. Different electronic components are mounted on the main board 2 and interconnected through the main board 2. At the same time, a main control chip 14 (in conjunction with) is also provided on the main board 2. Figure 4 The main control chip 14 can control and coordinate the operation of various electronic components, while the outer casing 1 is used to provide protection for the motherboard 2 and various electronic components.
[0040] When multiple electronic components are set, the structure of the headphone functional part may be too long, resulting in insufficient compactness. In order to solve the problem of insufficient compactness of the headphone functional part, this embodiment sets different electronic components on opposite sides of the motherboard 2.
[0041] Specifically, refer to Figure 2 and Figure 3On one side of the motherboard 2, a battery 3 and an in-ear detection element 4 are stacked along the thickness direction. The thickness direction of the motherboard 2 can be understood as a straight line perpendicular to the plane of the motherboard. At the same time, on the other side of the motherboard 2, an antenna 5 is stacked along the thickness direction. At this time, the motherboard 2 is connected to the battery 3, the in-ear detection element 4, and the antenna 5 respectively. Specifically, the motherboard 2 is electrically connected to the electronic components such as the battery 3, the in-ear detection element 4, and the antenna 5. By setting different electronic components on opposite sides of the motherboard 2 and connecting the electronic components to each other through the motherboard 2, the vertical space of the motherboard 2 can be effectively utilized, thereby avoiding the need to arrange multiple electronic components side by side on the motherboard 2 along the width or length direction, shortening the structural width and effectively utilizing the structural space.
[0042] At the same time, refer to Figure 4 Based on stacking components such as battery 3, in-ear detection element 4, and antenna 5 on both sides of motherboard 2, the outer edge size of motherboard 2 can be further reduced. Here, the width of motherboard 2 is set to 12mm-14mm, and the length is set to 12mm-14mm. For ease of description, the width of motherboard 2 is defined as d1, and the length of motherboard 2 is defined as d2. When the length and width of motherboard 2 are less than 12mm, the size of motherboard 2 may be too small, resulting in insufficient installation space for various electronic components. When the width and length of motherboard 2 are greater than 14mm, the size of motherboard 2 may be too large, which means that the size of the outer casing 1 needs to be increased accordingly, resulting in an excessively large overall width or length of the functional part. Therefore, when the width and length of motherboard 2 are between 12mm and 14mm, the requirements for compact design and electronic component placement can be met simultaneously.
[0043] For example, the width and length of the motherboard 2 can be 12mm, 12.5mm, 12.65mm, 13mm, 13.5mm or 14mm. In another embodiment, the length and width of the motherboard 2 can also be set within the range of the above parameter values, and no specific limitation is made here.
[0044] In this embodiment, by adopting the above-mentioned scheme, the battery 3, the in-ear detection element 4, and the antenna 5 are first stacked on opposite sides of the motherboard 2. This can compress the assembly space between different components as much as possible, resulting in a reasonable layout. On this basis, by limiting the width and length of the motherboard 2 to 12mm-14mm, sufficient component placement area can be obtained while meeting the basic connection requirements between the components. In addition, the overall width of the internal stacked structure of the functional part can be effectively shortened, thereby shortening the overall width of the functional part. The structural compactness is optimized and improved, and the problem of insufficient compactness of the functional part is solved.
[0045] Furthermore, continue to refer to Figure 4 To accommodate more functional components within a limited workpiece area, this embodiment includes a connecting line 6 within the ear beam 1001 and a main board 2 within the functional section. The main board 2 has a connector 7, preferably a BTB connector 7. A BTB (Board-to-Board) connector 7 refers to a connector 7 used to connect two or more circuit boards (PCBs). Furthermore, an FPC line 8 is provided between the connector 7 and the connecting line 6. FPC stands for Flexible Printed Circuit. Specifically, multiple solder points can be added to the FPC to connect the connecting line 6 in the ear beam 1001 to the solder points on the FPC line 8. Then, the FPC line 8 is stacked on top of the main board 2. This increases the vertical space utilization of the main board 2, freeing up more space for additional components. This improves the structural compactness, optimizes the component layout, and reduces the overall size of the functional section.
[0046] Furthermore, referring to Figure 3 The motherboard 2 has a contact piece 9 that abuts against the antenna 5. The contact piece 9 is mounted on the motherboard 2 and electrically connected to it. At the same time, the contact piece 9 has an outwardly protruding elastic abutment. The contact piece 9 abuts against one side surface of the antenna 5 through the elastic abutment, thus achieving conduction with the antenna 5. In this case, the conventional antenna 5 usually needs to be connected to the motherboard 2 by wires during installation. In this embodiment, the wire structure in the conventional solution is omitted by contact conduction, making the structure more compact. In addition, when installing the antenna 5, it is only necessary to press the antenna 5 into contact with the contact piece 9, which also simplifies the assembly difficulty between the antenna 5 and the motherboard 2.
[0047] Furthermore, referring to Figure 3 A spacer 10 is stacked between the battery 3 and the motherboard 2. Optionally, the spacer 10 is insulating, and the insulating material can be selected according to actual needs. For example, in this embodiment, the spacer 10 is made of EVA pad material. EVA refers to ethylene-vinyl acetate copolymer, which is a general-purpose polymer with insulating function. It is understood that in actual use, the spacer 10 can also be replaced with PC, PP, or insulating foam, etc. There are no specific restrictions here. Here, by stacking the spacer 10 between the battery 3 and the motherboard 2, the opposite sides of the spacer 10 abut against the battery 3 and the motherboard 2 respectively. When the battery 3 is connected to the motherboard 2, the spacer 10 is used to separate the battery 3 and the motherboard 2, so as to achieve insulation protection for the battery 3 and the motherboard 2. At the same time, the spacer 10 has a relatively thin and light structural size, which can well meet the requirements of structural compactness. While meeting the requirements of structural compactness, it can also prevent the motherboard 2 from short-circuiting due to accidental contact with the battery 3, making the structure safer and more reliable.
[0048] Furthermore, the outer casing 1 of the functional unit typically has shape requirements, such as needing the motherboard 2 to be curved. In this case, the corners of the motherboard 2 may affect the overall dimensions of the outer casing 1, resulting in a less compact structure. Based on this, continue referring to... Figure 3 The side edges of motherboard 2 in the width direction and the side edges in the length direction are chamfered for a smooth transition. It is understood that the chamfering filtering method of motherboard 2 includes at least two types: straight transition and curved transition. The specific transition contour of the chamfer can be set according to actual needs, and no specific restrictions are made here.
[0049] Based on the above structural design, the chamfered transition method can further reduce the corner size of the motherboard 2, reduce the empty area, and also match the outer shell 1 to form a curved shape, thereby optimizing and improving the space utilization of the motherboard 2.
[0050] Furthermore, battery 3 is connected to motherboard 2 via wires, and the width of motherboard 2 is no greater than the width of battery 3. Based on the above configuration, in the stacked structure, battery 3 is usually a button battery. In order to improve the battery life of the headphones, battery 3 usually occupies a large structural space inside the shell. On this basis, by setting the width of motherboard 2 to be smaller than the structural width of battery 3, the final width of the functional part can be close to the width of battery 3, which is equivalent to compressing the structural width of the functional part as much as possible. In this way, the size layout of the structure can be optimized while meeting the requirements of long battery life.
[0051] Reference Figure 5 To achieve the ear-in detection function, the ear-in detection element 4 can be a capacitive sensor or an infrared proximity sensor. The ear-in detection element 4 is electrically connected to the motherboard 2. It is mainly used for ear-in detection to improve the user experience. Its structure and principle will not be described in detail here.
[0052] At this time, when the in-ear detection element 4 is stacked on the motherboard 2, the overall thickness of the functional part may be increased. In order to further optimize the structural compactness of the functional part, a first groove 11 is recessed in the inner wall of the outer shell 1 near the in-ear detection element 4. The opening outline and opening size of the first groove 11 are adapted to the in-ear element. At this time, the in-ear detection element 4 can be attached to the first groove 11, so that the in-ear detection element 4 can be embedded in the inner wall of the outer shell 1.
[0053] Based on the above structural design, on the one hand, the first groove 11 can provide a place to accommodate the in-ear detection element 4, which is conducive to shortening the overall thickness of the functional part; on the other hand, the first groove 11 can also provide a positioning effect for the in-ear detection element 4, so that the installation stability and installation accuracy of the in-ear detection element 4 can be further optimized and improved.
[0054] Furthermore, referring to Figure 3 Most current headsets have call functionality, so a microphone module is usually integrated on the motherboard 2. To ensure that the microphone module can clearly pick up sound, a microphone sleeve 13 is usually put on the microphone module to prevent contamination, damage or corrosion of the microphone under long-term use.
[0055] Based on this, a microphone sleeve 13 is provided on the side of the motherboard 2 near the antenna 5. Normally, the microphone sleeve 13 is glued and fixed to the motherboard 2 and fits onto the outside of the microphone module to protect the microphone module. However, the microphone sleeve 13 has a certain size and thickness, which may increase the overall thickness of the functional part and may also cause structural interference with the antenna 5, resulting in the microphone sleeve 13 being squeezed and deformed, affecting the sound reception effect. Based on this, this embodiment also provides a clearance opening 131 at the antenna 5 for the microphone sleeve 13 to pass through.
[0056] Based on the above structural configuration, when assembling the electronic components of the functional part, by inserting the microphone sleeve 13 into the clearance opening 131, on the one hand, structural interference can be avoided, and on the other hand, the stacking distance between the motherboard 2 and the antenna 5 can be further increased, and the stacking thickness of the functional part is reduced.
[0057] Reference Figure 6 When the antenna 5 is stacked on one side of the motherboard 2, under the conventional structural setting, although the length and width of the functional part are shortened, the overall thickness of the functional part may be increased. Based on this, a second groove 12 is provided on the surface of the inner side of the housing 1 near the antenna 5, and the opening outline and opening size of the second groove 12 are adapted to the outer outline of the antenna 5. At this time, the antenna 5 is attached to the second groove 12, thereby embedding the antenna 5 into the inner side of the housing 1.
[0058] Based on the above structural design, on the one hand, the second groove 12 can provide a place to accommodate the antenna 5, which is conducive to shortening the overall thickness of the functional part; on the other hand, the second groove 12 can also provide a positioning effect for the antenna 5, so that the installation stability and installation accuracy of the antenna 5 can be further optimized and improved.
[0059] Example 2:
[0060] Based on Example 1, features not explained in this example will be explained using the methods described in Example 1, and will not be repeated here.
[0061] Reference Figure 7This utility model further provides an earphone, which includes the earphone functional part as described in Embodiment 1, and also includes an ear bridge 1001 and a speaker part 1002. The ear bridge 1001 is composed of plastic-coated memory steel wire and a connecting wire 6, providing elastic clamping force. The speaker part 1002 has a sound outlet and includes a speaker module inside, which is connected to the main board 2 via the connecting wire 6 in the ear bridge 1001. Furthermore, the earphone functional part and the speaker part 1002 are respectively located at both ends of the ear bridge 1001. Under the elastic support of the ear bridge 1001, the earphone functional part and the speaker part 1002 can be stably worn on the user's ear by clamping. Through the optimization and improvement of the earphone functional part, the overall structure of the earphone is compact and aesthetically pleasing, suitable for long-term wear.
