Description

[Detailed Description of the Invention] The present invention relates to an earphone that is used by being attached to a concave portion of the auricle, and particularly to an earphone that has an improved cord extraction portion from the earphone body.

First, a conventional earplug-type earphone will be described with reference to FIGS. 1 and 2.

An example of the configuration of a conventional earplug-type earphone is shown in FIG.

In FIG. 1, 1 is the earphone body,
It has a built-in electroacoustic transducer (not shown).
A cord 3 is connected to this conversion element through a flexible bushing 2, and an electrical signal in an audio frequency band is supplied.

As shown in the figure, conventionally, the "I"-shaped bushing 2 is attached to the disc-shaped earphone body 1 in the radial direction, and therefore, the direction in which the cord 3 is pulled out from the earphone body 1 is the radius of the earphone body 1. It is in the direction.

FIG. 2 shows how a conventional earphone is used. In FIG. 2, the earphone main body 1 is attached to a recess b of an auricle a and supported by a tragus c and a tragus d, which are part of the auricle. Generally, the intertragal notch e between both beads c and d is formed toward the facial skin, so when the user wears earphones, the butting 2 is guided toward the facial skin by the intertragal notch e. . The cord 3 pulled out downward from the bushing 2 touches or separates from the user's facial skin while using the earphones, giving the user a strange or uncomfortable feeling.

The present invention aims to eliminate this drawback by maintaining the direction in which the cord is pulled out from the earphone body at a predetermined angle on the opposite side of the auricle.

Hereinafter, an embodiment of the earphone according to the present invention will be described with reference to FIGS. 3 to 5.

FIG. 3 shows the overall structure of an embodiment of the present invention, and FIG. 4 shows the structure of its main parts. Further, FIG. 5 shows the usage state of one embodiment of the present invention. In these FIGS. 3 to 5, parts corresponding to those in FIGS. 1 and 2 are given the same reference numerals.

In FIGS. 3 and 4, reference numeral 20 denotes a bushing, which is formed, for example, from soft vinyl chloride resin into a bent bellows shape.

As shown in FIG. 4, in this embodiment, one end 21 of the bushing 20 is attached to the earphone body 1 in the radial direction, and the other end is bent to form a predetermined angle with the one end 21. The cord 3 is pulled out from the section 22. This results in code 3
As shown in FIG. 3, the pull-out direction is a direction that is offset by a predetermined angle θ with respect to the radial direction of the earphone body 1. It is preferable that θ is neither too large nor too small, and approximately 30° is appropriate.

As shown in FIG. 5, when the earphone of this embodiment is in use, one end 21 of the bushing 20 is guided downward between the tragus c and the tragus d of the auricle a, as in the conventional case. Also, the cord 3 held at the other end 22 is deviated by a predetermined angle θ in the anti-tragus direction, passes over the earlobe f, and prevents the part of the cord 3 beyond that from touching the facial skin. be done. Therefore,
Unlike when using conventional earphones, the cord does not touch your facial skin and cause discomfort, and the cord covering material does not deteriorate due to chemical reactions with skin oil or cosmetics. .

In the above-described embodiment, the material of the bushing 20 is, for example, soft vinyl, and is formed into a bent bellows shape, but it goes without saying that the material and shape are not limited to this.

For example, although not shown, it is also possible to apply a coating made of a material that can be formed into a desired shape by heat to the drawn-out portion of the cord, and to hold the cord at a predetermined angle by heating.

The embodiments in which the present invention is applied to earplug-type earphones have been described above, but the present invention can also be applied to other types of earphones.

Claims (1)

[Scope of Claim for Utility Model Registration] An earphone body that has a built-in electroacoustic transducer and is formed so as to be supported by a part of the auricle when it is attached to a concave part of the auricle; , an earphone in which a connection cord that supplies a signal to the electroacoustic transducer element is led out below the auricle when the earphone body is attached to a concave part of the auricle, and the connection cord is connected to the tragus of the auricle. It is characterized by being provided with a lead-out part that leads out downward between the tragus and a cord holding part that holds the cord at a predetermined angle in the direction of the tragus with respect to the lower part of the auricle between the tragus and the tragus. earphones.
