Abstract

This invention provides an earphone structure comprising a shell and at least one button. The shell has a through button hole and at least a pair of positioning posts. The button includes a pressing part that can be pressed into the button hole, a connecting piece, and a connecting part that connects the two. The connecting piece has at least a pair of through holes forming perforations, allowing the connecting piece to elastically deform and securely engage with the positioning posts when fitted with the perforations. Furthermore, the pairing of positioning posts prevents the connecting piece from causing the pressing part to sway and disengage from the button hole. Therefore, the button and shell of this invention can be easily assembled, allowing the button to be securely positioned on the shell. This not only maintains the normal operation of the button but also saves on bonding processes such as hot-melt welding or glue application, effectively reducing the overall production cost of the earphone.

Description

Headphone Structure Technical Field

[0001] This invention relates to an earphone structure, and more particularly to an earphone structure that reduces the assembly cost of buttons. Prior Technology

[0002] The existing headphone structure includes button components. In order to prevent the button components from falling off during use, which would cause damage or even loss of function, the button components are usually fixed to the inside of the existing headphone structure shell by means of hot-melt connection or glue application.

[0003] However, existing headphone structures require the button components to be assembled into the shell before hot-melt bonding or glue application. These additional bonding steps not only increase labor and time costs but also require the production of jigs and the consumption of glue. Moreover, these costs increase with production volume. Therefore, the overall production cost of existing headphone structures is relatively high, and there are indeed areas that need improvement. Summary of the Invention

[0004] To address the issue of high production costs in existing headphone structures, this invention provides a headphone structure that effectively improves upon existing technologies by using a positioning structure for the connecting piece and the shell to interlock appropriately through elastic deformation.

[0005] The headphone structure provided in this work includes: A housing includes at least one button hole and at least one positioning structure, the button hole extending through the housing, and the positioning structure including at least a pair of positioning pins; and At least one button, which is attached to the housing, the button comprising A pressing part, which is pressably engaged with the button hole; A connecting piece, which can be connected to the positioning structure, includes at least one pair of through holes and at least one pair of grooves, the grooves extending from a corresponding through hole to the outer edge of the connecting piece, such that the through hole forms a perforation, and the connecting piece can elastically deform and engage with the positioning post when the through hole is fitted onto a corresponding positioning post; and A connecting part is provided, which connects the pressing part and the connecting piece, and allows the pressing part to move relative to the connecting piece.

[0006] By utilizing the aforementioned technical features, since at least one pair of perforations on the button are perforations, they can elastically deform when fitted onto at least one pair of positioning posts on the housing. The elastic restoring force keeps the connecting piece firmly engaged with at least one pair of positioning posts. At the same time, the pair arrangement of the positioning posts also prevents the connecting piece from causing the pressing part to wobble and disengage from the button hole position. Therefore, the headphone structure of this invention can easily assemble the button and the housing, so that the button is firmly positioned on the housing. This not only maintains the normal operation of the button function, but also saves the process of joining by hot melt connection or glue application, effectively reducing the overall production cost of the headphone.

[0007] In the aforementioned headphone structure, the at least one pair of perforations and the at least one pair of grooves are arranged along a distribution direction.

[0008] In the aforementioned headphone structure, the connecting portion is connected to the bonding piece along an extension direction perpendicular to the distribution direction.

[0009] In the aforementioned headphone structure, a stepped shoulder is formed around the pressing part. When the pressing part is not operated, the shoulder abuts against the inner wall of the housing around the button hole.

[0010] In the aforementioned headphone structure, the pressing part of the button, the connecting piece, and the connecting part are integrally formed components.

[0011] In the aforementioned headphone structure, the connecting part includes two elastic arms, which are spaced apart and respectively connected between the pressing part and the connecting piece.

[0012] In the aforementioned headphone structure, the middle section of each elastic arm forms at least one bent segment. Simple Explanation of the Diagram

[0014] To gain a detailed understanding of the technical features and practical effects of this invention, and to enable its implementation according to the instructions, the preferred embodiments shown in the figures are further described in detail below:

[0015] This invention provides an earphone structure, the preferred embodiment of which is shown in Figures 1 to 4. The earphone structure of this invention includes a shell 10 and at least one button 20. The shell 10 includes at least one button hole 12 and at least one positioning structure 13. As shown in Figure 4, the button hole 12 is disposed through the shell 10, and the positioning structure 13 includes at least a pair of positioning posts 131. Specifically, the button hole 12 is disposed through the side wall of the shell 10, connecting the internal space 11 of the shell 10 with the outside of the shell 10; the positioning structures 13 are disposed at intervals not far from the button hole 12.

[0016] As shown in Figures 3 to 6, the button 20 is attached to the housing 10. Specifically, it protrudes from the housing 10 through the button hole 12 within the internal space 11 and includes a pressing part 21, a connecting part 22, and a connecting piece 23. As shown in Figures 3, 4, and 7, the pressing part 21 is pressably attached to the button hole 12. The connecting part 22 connects the pressing part 21 and the connecting piece 23, and as shown in Figure 7, allows the pressing part 21 to move relative to the connecting piece 23. The connecting piece 23 can be attached to the positioning structure 13 and includes at least one pair of through holes 231 and at least one pair of grooves 232. The grooves 232 extend from a corresponding through hole 231 to the outer edge of the connecting piece 23, forming a hole in the through hole 231, and allowing the connecting piece 23 to elastically deform and engage with the positioning post 131 when the through hole 231 is fitted onto the corresponding positioning post 131.

[0017] By means of the above-mentioned technical features, since at least one pair of perforations 231 of the button 20 are perforations, they can be elastically deformed when fitted onto at least one pair of positioning posts 131 of the shell 10. The elastic restoring force keeps the connecting piece 23 firmly engaged with at least one pair of positioning posts 131. At the same time, the pair arrangement of the positioning posts 131 can also prevent the connecting piece 23 from causing the pressing part 21 to wobble and disengage from the button hole 12. Therefore, the headphone structure of this invention can be easily assembled with the button 20 and the shell 10, so that the button 20 is firmly positioned on the shell 10. This not only maintains the normal operation of the button 20, but also saves the process of hot melt connection or glue dispensing, effectively reducing the overall production cost of the headphone.

[0018] In this preferred embodiment, a headset is used as an example. It has earcup shells 10 and 70 on both sides and a headband shell 80, and only one earcup shell 10 has one button 20, but this is not a limitation. In other embodiments, one or more buttons 20 can be provided on both earcup shells 10 and 70, and even the headband shell 80 can be provided with buttons 20 if needed, as long as the corresponding shells 10, 70, and 80 have a corresponding number of button holes 12 and positioning structures 13 for each button 20 to engage. Furthermore, the headphone structure described in this invention is not limited to headsets. As long as it has a shell 10 and at least one button 20, and the button 20 and the shell 10 are engaged with each other through the aforementioned detailed structure, it falls within the scope of protection of this invention.

[0019] In this embodiment, as shown in Figures 5 and 7, at least one pair of perforations 231 and at least one pair of grooves 232 of the aforementioned bonding piece 23 are arranged along a distribution direction D. Specifically, there are two perforations 231, spaced apart along the distribution direction D. The corresponding grooves 232 are located on both sides of the bonding piece 23, extending along the distribution direction D from the corresponding perforations 231 to the outer edge of the bonding piece 23. This reduces the manufacturing difficulty of forming the perforations 231 and grooves 232 on the bonding piece 23, shortens the length of the grooves 232, and avoids the risk of breakage due to insufficient structural strength of the bonding piece 23.

[0020] Furthermore, the connecting part 22 is connected to the connecting piece 23 along an extending direction E, and the extending direction E is perpendicular to the aforementioned distribution direction D. In this way, the part where the connecting part 22 extends to the connecting piece 23 has higher structural strength and is less prone to deformation compared to the part parallel to the distribution direction D. Therefore, if the pressing part 21 is pressed and swings slightly, it can be limited to a range that can be smoothly reset, thereby improving the operational reliability of the button 20.

[0021] Please refer to Figures 5 and 7. A stepped shoulder 211 is formed around the pressing part 21. When the pressing part 21 is not operated, the shoulder 211 abuts against the inner sidewall 14 of the housing 10 around the button hole 12. In this way, after the pressing part 21 is operated and elastically reset, it can be positioned in the same position, improving the quality of the pressing function and the reliability of operation.

[0022] In this embodiment, the pressing part 21, the connecting part 22, and the connecting piece 23 of the button 20 are integrally formed components. However, in other embodiments, these components can also be manufactured separately and then assembled together, and are not limited to being integrally formed.

[0023] More specifically, in this embodiment, as shown in Figures 4, 5, and 7, the connecting portion 22 of the button 20 includes two elastic arms 221. These two elastic arms 221 are spaced apart and connected between the pressing portion 21 and the connecting piece 23, respectively. Both elastic arms 221 are connected to the connecting piece 23 in an extension direction E perpendicular to the distribution direction D. Preferably, each elastic arm 221 has at least one bent section 222 in its middle section. Therefore, as shown in Figure 7, when the pressing portion 21 is pressed by the user, the two elastic arms 221 and their bent sections 222 can provide stable and appropriate elastic deformation, helping the pressing portion 21 maintain linear movement relative to the connecting piece 23 within a set range of motion, thereby improving the quality of the pressing function and the reliability of operation.

[0024] The above description is merely a preferred embodiment of this invention and is not intended to limit this invention in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in this invention without departing from the scope of the technical solution provided in this invention shall still fall within the scope of the technical solution of this invention.
