  As described above, the present invention provides a sound insulation film that is an annular thin film that is in close contact with the inner ear according to the arcuate surface change when the earplug is inserted into the inner ear, and provides the earplug with a waterproof function, At the position where the annular thin film is in close contact with the inner ear, the sound outside the ear is transmitted by the resonance action of the annular thin film, and the sound can be heard in the same manner.

  As shown in FIGS. 1 and 2, two earplugs 11 of the present invention are installed as a set. A column hole 20 is installed in the center of the drawing column 13 of each sound insulating film 12, and a connecting string 14 is inserted and installed in the column hole 20. In this way, the two earplugs 11 are connected to each other. Each one of the earplugs 11 is formed by integrally molding two portions of the sound insulating film 12 and the pulling pillar 13, the sound insulating film 12 is in the form of an annular film, and the pulling pillar 13 is the center of the sound insulating film 12 in the form of a thin film. The columnar body extends a certain length to the outside and provides convenience when pinching earplugs. When the ear plug 11 is inserted into the inner ear of the ear, the sound insulating film 12 which is an annular thin film is in close contact with the arc inner surface change of the inner ear of the ear and functions as a waterproofing to the ear plug 11. provide. Furthermore, at the position where the annular thin film is in close contact with the inner ear, the sound outside the ear can be heard like the ear due to the resonance action of the annular thin film.

  Next, as shown in FIGS. 1 to 6, the sound insulating film 12 and the pull column 13 of the earplug 11 are integrally formed of a silicon rubber material. The pulling column 13 installed at the center of the sound insulating film 12 includes a column body having an appropriate length, one end of the column body and the sound insulating film 12 are integrally connected, and an annular protrusion 19 is provided at the opposite end of the column body. Install. A column hole 20 is installed in the center of the end. The column body is installed in the center of the sound insulating film 12, and can be pinched when the ear plug 11 is inserted into the ear, thereby providing convenience. The sound insulating film 12 installed at one end of the pulling pillar 13 is in the form of a single-layer annular thin film, and the annular thin film forms the same annular thin film as at least two different standard film portions 15 and 16. A clear spacing edge 17 is formed between the two film portions 15 and 16. The standard of the spacing edge 17 is provided to many users based on the most common inner ear size of the human body as a basic unit. When the earplug 11 is inserted into the inner ear, the earpiece 11 is in close contact with the membrane portions 15 and 16 on both sides of the spacing edge 17, but this tensionless close contact surface does not cause the user to feel pressure.

  The inner membrane portion 15 installed at the front end of the sound insulating membrane 12 is a relatively small standard annular thin film, the tip of the inner membrane portion 15 has an arc shape, and the inner membrane portion 15 is inserted when the earplug 11 is inserted into the inner ear. The fifteen membrane surfaces are introduced at appropriate positions according to changes in the shape of the inner ear. Finally, the annular thin film and the inner ear surface are in close contact with each other, and the annular thin film is in contact with the inner ear in a close contact manner. The outer membrane portion 16 is installed at the rear end of the sound insulating membrane 12, a spacing edge 17 is installed between the outer membrane portion 16 and the inner membrane portion 15, and the sound insulating membrane 12 is separated by the spacing edge 17. Contains two different membranes. The outer membrane portion 16 installed at the rear end of the sound insulating membrane 12 is introduced into the inner membrane portion 15 in accordance with the shape change of the inner ear after the earplug 11 is inserted into the inner ear. If the membrane surface of the inner membrane portion 15 cannot be brought into close contact with the inner ear periphery, the earplug 11 advances to a deeper position. At this time, the film surface of the outer membrane portion 16 and the inner ear surface are in contact with each other, and the sound insulating film 12 is in close contact with the inner ear surface.

  The sound insulating film 12 of the earplug 11 is an annular thin film, and a drawing pillar 13 having an appropriate diameter is installed at the center of the annular thin film, and an intra-membrane space 21 is provided between the sound insulating film 12 and the drawing pillar 13. With The in-membrane space 21 is located at a contact position between the sound insulating film 12 and the pull column 13, and when the earplug 11 is inserted into the inner ear, only a part of the outer membrane portion 16 comes into close contact with the inner ear. The inner film part 15 installed at the tip of the sound insulating film 12 does not come into contact. The inner membrane portion 15 at the tip of the non-contact is separated by a single-layer membrane surface, and the outer end of the sound insulating membrane 12 is completely communicated with the outside world, so that the sound outside the ear is also affected by the use of the ear plug 11. It is transmitted to the ear normally without receiving. When the sound outside the ear enters the in-film space 21 of the sound insulating film 12, it is transmitted into the ear by a resonance transmission system. On the other hand, by inserting the ear plug 11 into the ear, the sound insulating film 12 and the inner ear are in close contact with each other, and an expected waterproof effect can be achieved. That is, even when the earplug 11 is inserted, external sounds can be heard as usual.

  Next, as shown in FIGS. 3 to 5, when the earplug 11 is inserted into the inner ear by grasping the pull column 13, first, in the earplug 11, first, the inner membrane portion 15 of the sound insulating membrane 12, the outer membrane Part 16 contacts the inner ear. The inner membrane portion 15 is brought into contact with, brought into close contact with, and introduced into the membrane-like annular surface, and when the earplug 11 is completely inserted into the ear, the sound insulating membrane 12 is in a most comfortable state without being subjected to pressure. Achieves the function by the membrane surface contact method and realizes the expected use of waterproof earplugs. Further, as shown in FIG. 6, when the earplug 11 is in the most comfortable close contact state without receiving pressure, the inner membrane portion 15 installed at the tip of the earplug 11 is isolated only by a single layer thin film. The external sound is resonated by the in-film space 21 of the sound insulating film 12 and is transmitted into the ear. Thus, after wearing the earplug 11, in addition to the waterproof function, sounds outside the ear can be heard, and conversation can be performed on the water surface even when the earplug is worn.
