Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an earbutt attached to a sounding body of a headphone and a method for manufacturing the same.

The sounding body of the headphones is made of a spongy material with moderate elasticity, which softens the sound before listening when worn, feels good on the skin and eliminates discomfort, and prevents listening fatigue even when used for a long time. Ear bats are attached.

Fig. 1 shows an example of a conventional ear butt and the state in which it is worn.The ear bat (f) has a recess (1-2) on one side of the butt body (1-1), and the open end of the recess is It has a structure with a locking edge (1-8) that protrudes inward,
To the headphones (2), attach the above locking edge to the sounding body case (
It is attached to the flange part (2-2) provided in 2-1) by being engaged with the collar part (2-2). For this reason, conventional ear butts have to be structurally molded using molds, etc., which increases the manufacturing time and costs. Since the headphone is simply attached to the flange provided on the body case (2-1), there are inconveniences such as discomfort and falling off due to positional displacement during use of the headphone.

This invention was made in order to solve the above-mentioned conventional problems, and it is less expensive to manufacture than conventional earbutts, can be easily attached to headphones, and is completely resistant to misalignment and falling out. This paper proposes an ear rose i that does not occur and a manufacturing method thereof.

The ear butt for headphones according to the present invention has a bat body which is formed by cutting a bat material of a predetermined thickness into an arbitrary shape and size, and has the same shape and size as the bat body on one side. It is made by pasting a ring-shaped double-sided adhesive with a release paper on one side.

In other words, this invention is characterized in that it is attached to the headphone using a double-sided adhesive instead of the conventional concave-convex fitting method, and the bat body can be easily molded, as well as having a ring on one side of the bat body. Since it is only necessary to attach a ring-shaped double-sided adhesive, it has the advantage of being easier to process and cheaper to manufacture than conventional molding methods using molds. In addition, since it is attached to the headphone using a double-sided adhesive, it is easy and complete to attach, and there is no risk of it shifting or coming off during use.

FIG. 2 shows an example of an ear butt for headphones according to the present invention, in which one side of a circular butt body (1-1) has the same shape and size as the butt body, and has a peeling layer on one side. Donut-shaped double-sided adhesive with paper (1-8) (
1-2), the bat body (1-1) can be made, for example, by cutting a bat material of a predetermined thickness into a circular shape, and the double-sided adhesive (i-2) can be made, for example, by attaching release paper to one side. In this case, it can be made by punching out a donut shape from a suitable medium double-sided adhesive tape with . Note that the reason why the double-sided adhesive is formed into an annular shape is to listen to the sound emitted from the sounding body.

When attaching the ear butt (1) to the headphone (2), as shown in Fig. 2(b), the butt body (l)
-1) Peel off the release paper (1-8) of the double-sided adhesive (1-2) attached to one side and attach it to the flange (2-2) of the sounding body case (2-1). Also, as shown in Figure 8, the ear hook is similar to the sounding body case (8-
1) The size and shape of the flange of the case (
It can be installed by simply pasting it on a-2).

Further, in the method for manufacturing ear bats according to the present invention, holes of any shape and size are bored at equal intervals while continuously moving a double-sided adhesive tape with a release paper pasted on one side, and then the tape and A strip-shaped batt material having the same inner diameter is continuously fed and attached to the other side of the adhesive tape, and then the double-sided adhesive tape and the polymer of the batt material are placed in the same hole as the hole drilled in the double-sided adhesive tape. It is characterized by continuous punching on the center line in the same shape and larger than the punched hole.

According to this method, it can be manufactured using an existing punching die plenue device, and it is also possible to continuously produce one product using only the punching operation, which has the advantage that one manufacturing stroke can be made at a low cost.

An example of an apparatus for carrying out the method of the invention will be described below with reference to FIG.

In Fig. 4, the frame is the base plate, the α force is the fixed base installed opposite the top surface of the base plate through the required gap, 0 is J for double-sided adhesive tape perforation, 1 is for double-sided adhesive tape, α] is double-sided. Knife for drilling adhesive tape and bat material polymer, α force is knockout pin, Q6
is a double-sided adhesive tape rewind reel, α is a bat material roll'
The return reel, a''/) is a pinch roller, (to) is a sprocket that synchronizes the movement of the double-sided adhesive tape and each process position, and H is a product collection box.

The double-sided adhesive tape perforation knife (6), the polymer perforation knife (to), and the knockout pin α→ are designed to operate automatically in conjunction with the feed of the material, and the pinch roller α force is designed to be motor driven. Needless to say, the polymer perforation knife (1) has a larger diameter than the double-sided adhesive tape perforation knife (6), and the knockout pin Q4 has the same diameter as the polymer perforation knife (1).

When manufacturing circular ear butts using the above device, sprocket holes (2

1-8), and is further rewound to polymerize with the double-sided adhesive (21-8) over the entire length of the device.

In this state, first, fixed pitches (Fig. 5) are perforated at equal intervals using a sprocket, and then, as shown in Fig. 6, the double-sided adhesive tape is fed with a pinch roller onto the double-sided adhesive tape with circular holes perforated. From the second part of the attached bat material (21-1), glue the bat material (21-1) on both sides with a polymer drilling knife 0 having a diameter larger than the circular hole on the same center line as the circular hole. The agent (21-8) and release paper (21-2) are perforated (
After that, the perforated portion is punched out using a knockout bin Q4, and as shown in FIG. An ear bat (1) to which a double-sided adhesive (1-2) is attached is manufactured.

The above-mentioned operations are repeated continuously, and the earbutt (1) falls into the collection box provided on the exit side and is collected.

When attaching ear bats manufactured in this way to headphones, a separate process is required to attach the release paper (
1-8) is peeled off and pressed onto the sounding body case (2-1).

In addition, when making a rectangular ear butt other than a circular ear bat, for example, it may be used in place of a rectangular piercing cutter.

As explained above, the earbutt for headphones according to the present invention has an extremely simple structure and is easy to attach to the headphone, and since it is an adhesive type, there is no problem of misalignment or detachment during use. No. Also,
Regarding the manufacturing method, it is possible to manufacture ear bats of any shape and size using relatively simple means, and mass production is also possible, so there is an advantage that the ear bats can be provided at a lower cost than conventional products.
