Description

Open/close earphone filter Open/close earphone filter The present invention relates to a filter. Conventional filters used in earphones are exposed to the outside, making them susceptible to contamination. Furthermore, they are manufactured in the form of stickers, presenting the difficulty of requiring periodic replacement. Additionally, they are difficult to purchase at reasonable prices in stores, and their adhesive strength deteriorates due to contamination from foreign substances during use. Consequently, cleaning the filters has been difficult. Accordingly, there have been proposals for replaceable disposable earphone filters, such as those found in Patent Publication No. 1020190102573; however, prior art, including the aforementioned prior art documents, is merely disposable, making it cumbersome to replace them every time, and it is difficult to clean or replace them unless the filter is available. Moreover, disposable filters have a negative impact on the environment and are inefficient economically, yet prior art does not take these factors into account. FIG. 1 is a perspective view of a hinged earphone filter according to an embodiment of the present invention, FIG. 2 is a front view of a hinged earphone filter according to an embodiment of the present invention, FIG. 3 is a rear view of a hinged earphone filter according to an embodiment of the present invention, FIG. 4 is a left side view of a hinged earphone filter according to an embodiment of the present invention, FIG. 5 is a right side view of a hinged earphone filter according to an embodiment of the present invention, FIG. 6 is a plan view of a hinged earphone filter according to an embodiment of the present invention, FIG. 7 is a bottom view of a hinged earphone filter according to an embodiment of the present invention. The adhesive surface (600) attached to the bottom surface of the lower frame (100) connects the nozzle part of the earphone with the filter. It is preferable to use a material with excellent adhesiveness and durability, such as silicone double-sided tape, for the adhesive surface (600). When the user cleans the filter, they hold the upper frame (200) and open the filter. At this time, the connecting part (400), which is attached to one side of the upper center of the lower frame (100) to allow the upper frame (200) to be opened and closed, and which connects the upper frame (200) and the lower frame (100), is manufactured using a hinge type. Additionally, the opening/closing groove (300), which is large enough for the user to open the upper frame (200) by hand, is attached to the lower frame (100). It is preferable to use a material such as mesh for the filter part (500) attached to the central hole of the upper frame (200) so that it can block foreign substances without affecting the sound quality as much as possible. In addition, as shown in FIGS. 1 and 7, the adhesive surface is the entire bottom surface of the lower frame. The hinged earphone filter of the present invention is not limited to the aforementioned embodiments and can be implemented with various modifications within the scope permitted by the technical concept of the present invention.
