DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to earphone earphones and hands-free earphone sets suitable for portable telephones, audio equipment, and the like.

[0002]

2. Description of the Related Art Portable mobile communication devices represented by mobile phones (hereinafter referred to as mobile phones) are widely used.
When talking, it is necessary to hold the mobile communication device in one hand.
However, this is inconvenient when performing various operations using both hands, such as while driving a car.

For this reason, a hands-free type set for two-way communication in which a cord having a plug connected to a connector of a portable telephone is provided with an earphone and a microphone is known. However, in this case, depending on how the earphone is inserted into the ear cavity, there is a problem that the earphone is detached from the auricle when the own weight of the cord or a pulling force is applied, and it becomes impossible to perform a smooth call. .

[0004] As a countermeasure, an earphone is attached to one end of an arch-shaped support member that can cross the head, and a "headband" equipped with a microphone unit in the other part, and a moderately soft frame on the back side of the pinna (ear ear). "Ear hooks" are known, in which an earphone and a microphone are arranged on a hanger formed with a loop or a hook that can be hooked on a knot.

However, the former "headband" is troublesome because the head is pressed by the headband and disturbs the hair. In addition, there is a problem that handling becomes troublesome because the whole is large, it is inconvenient to carry, and the price increases.

[0006] The latter "ear-hook" has a problem that it is quite difficult to fit the hanger exactly because the shape and size of the pinna nodules vary from person to person, and it is easy to come off during use. In particular, when the user wears eyeglasses, the vine and the double eyeglasses are hung on the pinna. For this reason, there has been a problem that the hooking becomes shallow and it is easy to fall off, or the eyeglasses come off when the eyeglasses are taken off. In addition, there is a problem that discomfort is likely to occur because the hanger portion contacts the auricular node. Furthermore, although the hanger is smaller than the headband, it is still rather bulky, which is inconvenient to carry in a pocket or the like.

[0007]

FIG. 7 shows an auricle edge portion 70.
This is an example in which an intermediate portion 701 is set. Each of the upper region 700 and the intermediate portion 701 has an outer cartilage 72 as schematically shown in FIG. 4C, and a second piece is provided at an inner end portion (a thinned portion) of the outer cartilage 72. 4 is in contact with the outer cartilage 72, and the edges 700 and 701 have a greater thickness in cross section toward the outer end and act as a retaining portion. Is held. Therefore, the gravitational force of the earphone 11, the microphone 12, and the cord portion thereafter is suppressed, and the earpiece 2 does not come off even if a tensile force acts. Further, since the outer cartilage 72 has a good sound transmission effect, it is also advantageous in hearing.

Further, the earpiece 2 is located immediately adjacent to the ear cavity,
Therefore, the distance from earpiece 2 to earphone 11 is very short. Therefore, even if the earphone 11 is removed without being pushed into the ear cavity, the gravity of the earphone 11 and the input line 1a reaching the earphone 11 can be reliably received, and the face may be shaken violently. Even the earpiece does not come off the pinna. Therefore, it is sufficient to push the earphone 11 into the ear cavity only during a call, so that discomfort caused by inserting the earphone 11 into the ear cavity for a long time can be eliminated, and normal conversation in the ear cavity can be easily performed. Can do it.

Since it is only attached in a cross shape to 70, the nodule behind the pinna is free, and there is no effect when wearing glasses or the like.

Further, since the earpiece 2 is very compact and attached to the pinna rim 70 in an intersecting manner as shown in FIGS. 4 and 7, it is not a fixture but an appearance as if an ornament is attached. Presents good appearance. By selecting the shape, material, and the like of the first piece 3, it is possible to enhance the appearance as a decorative product. And since it is compact and lightweight, when not in use, the cord can be rolled round and stored in a pocket or the like and carried.

The locking portion 5 has an opening 50 along one side through which a cord can be inserted and removed.
Since the earphone 11 can be attached to and detached from the ear, the direction of the first piece 3 can be easily changed depending on whether the earphone 11 is used with the right ear or the left ear. Therefore, one type can handle it,
It is economical.

The present invention can also be optionally mounted on the earlobe 71, as shown in FIG. In this case, since the earlobe 71 has no cartilage and is only a piece of meat and is thinner as it approaches the edge, the supporting and fixing force is weaker as compared with the case where the earlobe 71 is attached to the cartilage portion, but there is a concern that the earlobe 71 may come off due to gravity of the cord. Absent.
