(Embodiment 1)
Hereinafter, the present invention will be specifically described with reference to the drawings showing embodiments thereof. FIG. 1 is a perspective view showing a configuration of an earphone according to the present invention. FIG. 2 is a schematic cross-sectional view showing the configuration of the earphone according to the present invention, and shows a case where a user wears the earphone on one ear side.

  In FIG. 1, reference numeral 1 denotes a substantially disc-shaped bag body in which the center of a circle swells. A substantially circular opening 2 is formed at the approximate center of one surface of the bag body 1, and the inside and outside of the bag body 1 communicate with each other through the opening 2. It is like that. The bag body 1 is manufactured by stitching together fabrics having glass wool 6 sandwiched between two polyester sheets 5 and 5. The fabric is provided with substantially lattice-like seams 4 and quilted to prevent the glass wool 6 between the polyester sheets 5 and 5 from shifting.

  Further, the size of the bag body 1 is set to a size that covers the entire user's ear 100 inserted into the inside through the opening 2 and can be accommodated in the inside. The peripheral portion of the opening 2 of the bag body 1 is folded and stitched together, and rubber 7 is passed through the folded portion. The rubber 7 allows the peripheral portion of the opening 2 of the bag body 1 to expand and contract so that the opening 2 is expanded and contracted. When the user accommodates the ear 100 in the bag 1 and removes the bag 1 covering the ear 100, the user can enlarge the opening 2 and allow the ear 100 to pass.

  In a state where the bag body 1 covers the user's ear 100, the rubber 7 tightens the base portion of the user's ear 100, so that the bag body 1 does not easily fall off the ear 100. However, the rubber 7 is not very strong so that the user does not feel pain.

  A mounting portion 8 for mounting the speaker 11 is provided inside the bag body 1, and a substantially circular thin plate-like speaker 11 is detachably mounted on the mounting portion 8. The mounting portion 8 is disposed at a position substantially opposite to the opening 2 in the bag body 1, and when the bag body 1 covers the user's ear 100, the speaker 11 is positioned in the vicinity of the user's ear hole. 11 makes it easy for the user to hear the sound output from the terminal 11.

  Further, the cord 10 connected to the speaker 11 is led out of the opening 2 along the inner wall of the bag body 1 from the speaker 11. The earphone according to the present invention includes two bags 1 and two speakers 11, and is respectively attached to the left and right ears 100 of the user. The cords 10 connected to the two speakers 11 are respectively brought out of the bag body 1 and then combined into one to be connected to an audio device (not shown).

  FIG. 3 is a schematic enlarged sectional view of the earphone mounting portion 8 and the speaker 11 according to the present invention. A mounting portion 11a in which a substantially cylindrical protrusion is formed on a substantially circular metal plate smaller than the speaker 11 is bonded to an opposite surface of the speaker 11 from which sound is output. The protruding end of the protrusion of the mounted portion 11a is rounded into a substantially spherical shape, and the diameter is slightly larger than the base of the protrusion.

  The mounting portion 8 of the bag body 1 is made of a substantially disk-shaped metal having a size similar to that of the mounted portion 11a of the speaker 11, and is bonded with an adhesive. The thickness of the mounting portion 8 is approximately the same as the protrusion length of the protrusion of the mounted portion 11a, and an insertion hole 8a for inserting the protrusion of the mounted portion 11a is formed in the center. In the insertion hole 8a, the diameter of the opening portion of the hole is approximately the same as the diameter of the root portion of the mounted portion 11a, and the deep portion of the hole is slightly larger in diameter.

  When the speaker 11 is attached to the attachment portion 8, the protrusion of the attachment portion 11 a of the speaker 11 is pushed into the insertion hole 8 a of the attachment portion 8 with a certain force or more. In the state where the protrusion of the mounted portion 11a is inserted into the insertion hole 8a, the diameter of the protruding end portion of the protrusion is increased, so that the protrusion does not easily come out of the insertion hole 8a, and the speaker 11 is attached to the mounting portion. Do not fall off easily from 8. When the speaker 11 is removed from the mounting portion 8, the protrusion of the mounted portion 11a of the speaker 11 is pulled out from the insertion hole 8a with a certain force or more. The mounting portion 8 of the bag body 1 and the mounted portion 11a of the speaker 11 can be easily realized by using a hook-type button.

  FIG. 4 is a schematic view showing a state when the earphone according to the present invention is not used. When the earphone does not listen to the sound output from the audio device, first, the earphone cord 10 is disconnected from the audio device (see FIG. 4A). Next, one of the two bag bodies 1 is folded, and the folded bag body 1 is accommodated in the other bag body 1 through the opening 2 (see FIG. 4B). Next, the cord 10 is stored in the bag body 1 (see FIG. 4C). Accordingly, since the bag body 1 and the cord 10 are stored in one bag body 1 and gathered together (see FIG. 4D), the earphone can be easily carried.

  In the earphone having the above configuration, the bag body 1 in which the speaker 11 is housed is configured to be worn so as to cover the user's ear, so that the user does not feel pain in the ear and moves. There is no risk of the earphone falling off. In addition, since the fabric of the bag body 1 is a fabric in which the glass wool 6 that is a sound absorbing material is sandwiched between the polyester sheets 5, the sound output from the speaker 11 is difficult to leak to the outside of the bag body 1. In order to further enhance the sound insulation effect, for example, a plurality of polyester sheets 5 can be further stacked, or a silicone coating having a sound insulation effect can be applied to the polyester sheet 5. Moreover, since the cord 10 and the other bag body 1 can be stored in the bag body 1, the portability is good.

  In the present embodiment, the shape of the bag body 1 is a substantially disk shape with the center swelled, but is not limited to this, and other shapes such as a rectangular disk shape, a spherical shape, a cigar shape, or an ear shape are used. There may be a bag shape as long as it covers the ear and can be accommodated. Moreover, although the earphone showed the structure provided with the two bag bodies 1 for the left and right ears, the present invention is not limited to this, and is a structure provided with only one bag body 1 so as to be worn only on one ear.

  Moreover, although the structure which mounts | wears with the one speaker 11 in the bag body 1 was shown, it is not restricted to this, The structure which mounts | wears with the 2 or more speaker 11 in the bag body 1 may be sufficient. For example, the bag 1 may be provided with two speakers, one for low sounds and one for high sounds. Moreover, although the structure which takes out the cord 10 connected to the speaker 11 out of the bag body 1 from the opening 2 of the bag body 1 is shown, it is not limited to this, and the cord 10 is formed by forming a through hole in the bag body 1. The structure which lets it pass may be sufficient.

  Further, the fabric of the bag body 1 is a fabric in which the glass wool 6 is sandwiched between the polyester sheets 5 as a sound absorbing material, but is not limited thereto, and a sheet material such as polyolefin resin or vinyl chloride may be used. . Moreover, the structure which does not pinch the glass wool 6 between the polyester sheets 5 may be sufficient, and the structure which pinches | interposes another sound absorption material may be sufficient. Moreover, the structure which piles up more polyester sheets 5 and raises a sound-insulation effect may be sufficient, and the structure which piles up multiple types of sheet | seat materials may be sufficient. When a plurality of types of sheet materials are stacked, sound leakage can be more reliably prevented by using a plurality of sheet materials having different frequency bands for performing sound insulation efficiently. Moreover, although the structure which performs the quilt process to the bag body 1 was shown, the structure which does not restrict to this and does not perform a quilt process may be sufficient.

  Moreover, when the earphone is not used, the configuration in which the other bag body 1 and the cord 10 are stored in one of the two bag bodies 1 is not limited to this. Alternatively, only the cord 10 may be stored. Further, in the storing procedure shown in FIG. 4, the procedure for storing the cord 10 after storing the folded bag 1 in the bag 1 is shown, but the present invention is not limited to this, and the cord 10 is stored. You may store the bag body 1 folded later.
