Abstract

PROBLEM TO BE SOLVED: To eliminate the distortion of a sound due to a heavy low tone and improve the sound quality, and to cut off noise from the outside field by coupling an insert part for an ear hole which is mounted with soft synthetic resin with a recessed part covering the earphone whose end part is nearly flat and adhering a ring-shaped elastic body to the end part of the recessed part. SOLUTION: A pipe 3 to be inserted into the ear hole is connected to the outside center of the recessed part which is curved and made of synthetic resin and covers the earphone, and a penetrating thin hole 2 is bored in the flank of the recessed part 1. The periphery of the pipe 3 is covered or mounted with soft synthetic resin 4 which is freely compressible and deformable with a finger tip so as to improve to fit to the ear hole. Further, the ring-shaped elastic rubber-made body 5 in a cylindrical or truncated pyramid shape which can couple the recessed part 1 and earphone detachably is adhered covering the peripheral end part of the recessed part 1. Then the hole 6 of the ring-shaped elastic body 5 is expanded and the tip end surface is inserted into it and fixed by covering the outer periphery of the earphone with the ring-shaped elastic body.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an earphone accessory, and more particularly to an earphone accessory suitable for improving sound quality and blocking external noise when listening with a portable audio reproducing apparatus using the earphone.

[0002]

2. Description of the Related Art Conventionally, in portable audio reproducing apparatuses and portable radios, it is generally practiced to cut off external sounds when carrying and listen to the sound with earphones so as not to emit sounds to the outside. Generally, the earphone has a distal end projecting so as to be inserted into the ear hole, and an earphone having a substantially flat end and fixed outside the ear hole which is not directly inserted into the ear hole. However, recently, the latter type is more often used in terms of mounting and storage than the one in which the tip is directly inserted into the ear hole. In particular, this type is often used in portable audio reproducing devices.

However, in the sound reproduction by listening to the earphone, the sound is distorted due to heavy bass and the sound quality cannot be said to be sufficient. In addition, if the volume is increased during listening, there is also a problem that sound leaks to the outside world or noise easily enters from the outside world.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an earphone accessory capable of improving sound quality by eliminating distortion due to heavy bass when listening to the earphone, and capable of cutting off noise from the outside world. It is.

[0005]

Means for Solving the Problems In view of the above problems, the present inventor has conducted intensive studies, and as a result, an earphone accessory in which a portion to be inserted into an ear hole can be easily fitted and a cover can be easily attached to and detached from the tip of a conventional earphone. And completed the present invention.

In other words, the earphone accessory of the present invention has a curved concave portion capable of covering an end surface of the earphone having an insertion surface having a substantially flat end surface, and a pipe having a curved outer peripheral portion at the center of the outer periphery thereof. And an insertion tube into an ear hole formed by covering or attaching a deformable soft synthetic resin, and an annular elasticity capable of detachably connecting the earphone end face and the concave portion to an end of the concave portion. The body is attached.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an earphone accessory of the present invention will be described in detail with reference to the accompanying drawings.

An earphone accessory according to the present invention comprises a curved concave portion 1 as shown in the cross section of FIG. 2 which can cover the conventional earphone as shown in FIG. The tube 3 to be inserted into the tube is connected. The shape of the curved concave portion 1 is not particularly limited, but is preferably a circular container from the viewpoint of covering a conventional earphone. Further, it is preferable to provide a through hole 2 on the side surface of the curved concave portion 1 in order to reduce shock waves due to heavy bass and to eliminate discomfort particularly in long-time listening. This pore 2
Is preferably about one. The concave portion 1 is preferably made of synthetic resin in view of sound quality and moldability.

In addition, a tube 3 is provided at the center of the outside of the curved concave portion 1 to be inserted into an ear hole penetrating from the inside of the concave portion 1. The tube 3 may be formed integrally with the concave portion 1 using a synthetic resin, or may be connected by bonding, fitting, or the like using a combination of a synthetic resin and a metal. Furthermore, it is necessary to cover or attach around the tube 3 a soft synthetic resin 4 which can be compressed and deformed with a fingertip in order to further improve the fit with the ear hole. As the above-mentioned soft synthetic resin, a soft fine synthetic resin foam having low elasticity and compressibility which can be freely deformed, which is used in earplugs and the like, is preferable from the viewpoint of fit.

Further, an annular elastic body 5 capable of detachably connecting the curved concave portion 1 and a conventional earphone as shown in FIG. 3 is attached so as to cover a peripheral end of the concave portion 1. As shown in FIG. 1 and FIG. The annular elastic body 5 is preferably made of a material having high elasticity in order to detachably connect the earphone and the concave portion 1 as shown in FIG. 3, and in particular, a rubber cylindrical or frustoconical annular member is connected. Is preferred. Note that other soft plastic materials may be used.

Next, the earphone accessory of FIG. 1 and the earphone of FIG. 3 are connected by enlarging the hole 6 of the annular elastic body 5 of FIG. 1 and inserting the front end face 7 of the earphone there. By covering and fixing the annular elastic body to 8, the connection before use can be performed as shown in FIG. The size of the soft synthetic resin 4 in the ear hole insertion portion of the earphone accessory may be adjusted by compressing the size into the ear hole of the listener appropriately with a fingertip or the like, and then inserted into the ear hole to reproduce sound.

EXAMPLE A hole having a diameter of about 7 mm and a hole having a diameter of about 1 mm at the center of a concave portion made of a ball-shaped plastic having a diameter of about 20 mm, a depth of about 6 mm and a thickness of about 1.5 mm were formed.
Places. Next, a plastic tube having an outer diameter of about 7 mm, an inner diameter of about 4 mm, and a length of about 12 mm was inserted into the hole at the center bottom of the concave portion, and was adhered and fixed to form an earphone cover. A soft, fine synthetic resin foam having a low elasticity and a deformable compression restoring property was attached to the outer periphery of the plastic tube.

Next, a thickness of about 1 mm, a lower end diameter of about 17 mm, a maximum height of about 15 mm, a minimum height of about 9 mm, and a connection between the maximum height and the minimum height are formed at the circumferential end of the plastic ball-shaped earphone cover. An annular rubber having a diameter of about 13 mm and a circular truncated cone having an inclined upper end was covered, an opening at an upper end of the annular rubber was enlarged, and an earphone as shown in FIG. 3 was inserted and connected as shown in FIG.

Next, the soft fine synthetic resin foam portion was compression-adjusted with a fingertip and inserted into an ear hole to reproduce sound. As a result, there was no distortion particularly in the heavy bass compared to the case of the earphone alone, and improvement in sound quality was recognized. In addition, the external noise could be cut off, and the volume was about 60% of the conventional level, and a powerful feeling was obtained. In addition, there was no discomfort during long listening hours.

[0015]

The accessory for the earphone of the present invention is
Since sound quality can be improved, in particular, distortion in heavy bass can be eliminated and external noise can be cut off, a powerful sound with low volume can be obtained. In addition, since the user can listen at a lower volume than before, there is also an effect that the life of the battery can be extended.
