Description

Eartips and earphones

The present invention relates to an ear tip and ear earphones coupled to the audio sound equipment used.

Nowadays, many smartphone users use regular earphones or Bluetooth earphones with hands-free function when listening to music or talking on the phone. Usually, when purchasing a smartphone for the first time, bundled earphones are usually provided. In comparison with headphones, earphones may drop a little in volume, but due to their small size, they are easy to carry, so people live with the popularity of smartphones. It is a reality that has become a necessity.

If earphones are categorized, they can be classified into open and kernel earphones. In the early model, open type was used a lot, but nowadays, open type and kernel type are used in similar ratio.

The advantage of open earphones is that the speaker module inside the earphone housing

The yoke is not completely enclosed and the sound is not delivered directly, so some of the sound leaks out and you can feel comfortable. The advantage of the kernel-type earphone is that it has a noise-cutting effect, and regardless of the shape of the individual outer ear, each person has a strong fixation force due to good adhesion with the ear hole when the eartip is fitted to the width of the inner ear.

The open type earphone and the kernel type earphone have a complementary aspect. The earphone made in an effort to solve the problem of low frequency reproducing ability and external noise inflow due to fixation and sound leakage, which are disadvantages of the open type earphone, is a kernel type earphone. Contrary to the open earphones, it has a function of fixing power and noise blocking, but because it is in close contact with the ear canal, air circulation is not good, and the low range is strong, but each person has the disadvantage of feeling foreign body or stuffiness, and pain.

In addition, the kernel-type earphone minimizes external noise by making the speaker and ears close to each other as closely as the sealed headphones, so that there is little interference from surrounding sounds and the sound generated from the diaphragm does not leak to the outside. That is, it is possible to listen to music in places where external noise is severe and does not damage the surroundings. However, when used for a long time, the pressure of the ear tip close to the ear is relatively poor compared to the open earphone, and the sound of the diaphragm directly affects the eardrum, so that the eardrum may be impacted by the impact of air pressure. .

Therefore, the advantages of the open earphones and the kernel-type earphones, that is, to enhance the tightness, such as the kernel type to enhance the low range, the air cushion ear tips and air cushion that can be mounted on the open or kernel type earphones to improve the comfort of the external ear without a foreign object like an open type Earphones have been proposed. Details of the ear tip provided with the air cushion will be described later in the contents of the present invention.

The present invention is mounted on the existing open or kernel-type earphones to increase the adhesion to the ear hole of the earphone with a strong fixing force to the ear hole and can be coupled and detached to the kernel-type earphone as well as open type to prevent noise and the air flow inside the earphone The aim is to provide possible earphones and eartips.

Ear tip according to the present invention for achieving the object as described above, the body portion is covered with the entire outer peripheral portion of the earphone, the coupling of the opening form formed on the back of the main body portion so that the main body portion can be covered on the outer peripheral portion of the earphone An in-ear type induction part protruding from one side of the main body part to guide the sound output from the earphone into the ear, and an external part extending from the other side of the main body part so as to fix the earphone. A fixing portion fixed to the recessed portion of the outer portion, and provided inside the fixing portion, so that the fixing portion is easily fixed to the recessed portion of the outer ear regardless of the size of the recessed portion of the outer ear. It characterized in that it comprises an air cushion for applying a restoring force.

In the main body portion, it is preferable that a hole is formed in the front surface of the main body portion so as to adjust the bass through the inflow of air.

It is preferable that the outer diameter of the induction part gradually decreases toward the end in order to increase the sealing degree with the ear hole.

It is preferable that the induction part protrudes in an oblique direction with the front surface of the main body part in order to increase the seating feeling between the ear and the ear hole.

In addition, the air cushion earphone according to the present invention for achieving the above object, the main body portion is covered on the entire outer peripheral portion of the earphone, the main body is formed on the rear of the main body portion so that the main body can be covered on the outer peripheral portion of the earphone Opening coupling portion, an in-ear induction portion extending from one side of the main body portion so as to guide the sound output from the earphone into the ear, extending from the other side of the main body portion so that the earphone is fixed A fixing part protrudingly formed and fixed to a recessed part of the outer ear, and provided inside the fixing part, so that the fixing part is easily fixed to the recessed part of the outer ear regardless of the size of the recessed part of the outer ear. Ear tip including an air cushion for applying elastic restoring force to the fixing portion and the earphone is covered It characterized in that it comprises a main body.

The earphone main body includes a conduit part protruding from one side of the sound output to induce sound, and the conduit part is inserted into and coupled to the induction part of the ear tip.

As described above, the present invention has the following effects.

First, since the ear part is caught by the outer ear due to the fixed portion derived from the body of the ear tip and the air cushion therein, the earphone is easily fixed without being pulled out from the ear hole.

Second, since the sound coming from the speaker is guided into the ear hole without being counted out due to the fixed portion and the air cushion inside the ear hole, it is possible to make a sufficient sound even with a small volume. It works.

Third, since the air cushion ear tip is formed to be detachable from the earphone, there is a practical effect that one ear tip can be mounted and used in both the open earphone and the kernel earphone.

Hereinafter, preferred embodiments of the present invention as described above will be described with reference to the accompanying drawings.

1 is a perspective view showing the combination of the ear tip and the earphone. 1 shows the back of the eartip. In one embodiment according to the present invention, the eartip may be made of silicon. Ear tip of the present invention, the main body portion is covered over the entire outer peripheral portion 202 of the earphone, the opening portion coupling portion 101 formed in the rear of the main body portion so that the main body portion can be covered on the outer peripheral portion of the earphone, the earphone In-ear type induction part 102 formed to protrude from one side of the main body to protrude sound output from the ear and a fixing part protruding from the other side of the main body to fix the earphone And 104. In the embodiment, the earphone coupled to the ear tip is a modified earphone in which a conduit part 201 is formed to protrude sound in an open earphone, but is not limited thereto. It is also coupled to a general open earphone or a kernel earphone. It is possible.

Figure 2 shows the front of the eartip according to the present invention. What is seen in the front center is the hole 103, where the air can enter and exit and adjust the volume of the sound in the bass region. The fixing part 104, the induction part 102, and the coupling part (not shown) are integrally formed in the main body of the ear tip. Since the direction of the hole is toward the person's rear face while the induction part is inserted into the ear hole by combining the ear tip and the earphone, the front side blocks the hole partly so that air can be drawn in and the sound output from the earphone is relatively leaked. Will not.

3 is a perspective view when the ear tip is coupled to the earphone body. The earphone shown in FIG. 3 is worn on the left ear. Insert the induction part 102 into the ear hole and insert the fixing part 104 in close contact with the recessed part of the outer ear, and the fixing part is pressed when the air cushion formed between the ear tip and the outer circumference of the earphone main body inside the fixing part 103 is pressed. 104 is elastically fitted to the recessed portion of the outer ear.

4 is a cross-sectional view when the ear tip and the earphone body are combined. While the coupling portion of the ear tip is coupled in a form surrounding the entire outer circumference of the earphone body, an empty space between the ear tip and the outer circumference of the earphone is formed inside the fixing portion, which is an air cushion 105. In the earphone of the kernel-type earphone, most of the ear tip of the silicone material surrounding the conduit is inserted into the ear, which is a problem, but in the present invention, since only the induction part 102 of the ear tip of the silicon material is inserted into the ear, the effect of reducing the foreign body feeling is reduced. have.

Figure 5 shows a state wearing the existing open earphone in the ear. Figure 6 shows a state wearing the earpiece with eartip of the present invention in the ear.

In FIG. 5, the conventional open earphone is supported only at one part (a) of the outer ear, whereas in FIG. 6 wearing the earphone with the air cushion eartip of the present invention, it is supported at three parts of the outer ear. The first engaging portion (b), the part of the housing, the second fixing portion (c) and the third portion (d) the induction part constitutes the vertex of the triangle and doubles the fixing force with the outer ear. The second part (c) indicates the part of the outer ear where the fixing part is fitted into the recessed part of the outer ear.

A feature of the present invention is that the ear tip provided with the air cushion can be used in combination with the outer circumference of the existing earphone. Due to this feature, it can be expected to have a good effect in terms of sound quality by combining with general open type earphone which has good fit and performance.

The air cushion ear tip and the earphone body are coupled to each other, unlike the existing earphones, the coupling portion of the ear tip is configured in such a form to surround the entire housing of the earphone body. Compared to earphones, the conduit section is wrapped with silicone eartips. Due to the elasticity of the coupling portion of the ear tip of the silicon material may be combined with the earphone having a housing of various sizes.

Since the ear tip surrounds the entire portion of the sound of the earphone body, and is integrally formed with the induction part inserted into the ear hole, the collected sound is naturally transmitted to the ear through the induction part, so that the user can enjoy the effect of shielding. The present invention differs from the conventional hermetic kernel-type earphones in that, in the present invention, there is a hole in the surface of the air cushion eartip in which the coupling part, the induction part, and the fixing part are integrally formed so that air can freely enter and exit. The balance can be adjusted, and the surface facing the hole is in contact with the rear surface, so that the external sound is relatively blocked while the internal speaker sound is not leaked.

The air cushion ear tip of the present invention is also excellent in terms of its utilization since it can be combined with a general open earphone and a kernel earphone, that is, a earphone protruding from the conductive part. It is possible to combine with the earphone of various sizes because the product can be configured by changing the coupling portion of the air cushion ear tip according to various embodiments so that it can be combined with the outer peripheral portion of the earphone without having to replace the earphone newly.

When listening to music or talking on the phone in public places, users use earphones or headphones for various reasons. Earphones and headphones are a similar type of audio device, with different sizes of loudspeakers inside the housing and how they are worn on the ears. Each has advantages and disadvantages for each other, while headphones have many advantages in terms of sound quality that requires sound to be balanced so that they do not be distorted and reproduced, and earphones have relatively good portability. However, although portability is superior to headphones, it is true that the function is inferior to the headphones in terms of the fixing force of the device in close contact with the ear canal. Therefore, various methods have been studied in the related art in order to increase the fixing force of earphones. The ear caps and the fixing force, which are one of the features of the present invention, will be described with different paragraphs.

Since the appearance of the ear canal varies from person to person, it is true that the shape of earphones is uniformly limited in fixing power. Open earphones, which are the weakest form of fixation, are the typical case of the iPhone bundled earphones. The fixing force is maintained by hanging the earphone housing on the valley surrounding the ear hole with the speaker surface coming out of the ear. This may be strong or weak fixing force of the housing of the earphone depending on how deep the bone surrounding the ear hole. In most cases, if the bone supporting the housing is not deep, the fixing force is weak and the earphone is easily removed from the ear.

A feature of the present invention is to improve the problem of the existing open earphone, the air cushion earphone of the present invention compared to the open earphone has a difference in the angle between the ear hole and the earphone. In the present invention, since there is an induction part for collecting and inducing sound, the induction part formed by coupling the ear tip to the earphone may be inserted into the ear hole without having to closely contact the sound emitting surface of the open earphone with the ear hole. The induction part is characterized in that the oblique direction and the acoustic emission surface of the earphone. Therefore, since the sound emitting surface of the earphone does not need to be aligned with the ear hole, the ear tip may be fitted to the outer ear by using a fixing part formed on the other side of the main body. An empty space is formed inside the fixing part so that the ear tip and the earphone are combined to be inserted into the ear canal so that the empty space acts as an air cushion so that the fixing part can be elastically inserted into the recessed part of the outer ear and increase the fixing force. To be able. That is, it is fixed to the ear hole and the outer ear can be double fixed.

In practical terms, the ear tip of the present invention is easy to be combined with the housing of the general open earphone, easy to be combined with the earphone of the conduit form shown in Figure 1, even in the case of the kernel-type earphone by inserting the kernel-type earphone in the induction part It has many advantages because it can be used.

In terms of wearing comfort, in the case of using a secondary tool to fix the earphone to the ear canal, for example, in the case of the earphone in the form of a clip in the ear, it is a fact that many people feel uncomfortable because they feel fatigue and pressure due to long wearing. On the other hand, in the present invention, since the fixing force to the ear hole is supported by the silicon and the air cushion, the foreign body feeling and the feeling of pressure are reduced even when worn for a long time.

As described above, the detailed description of the present invention has been made by the embodiments with reference to the accompanying drawings, but since the above-described embodiments have only been described with reference to the preferred examples of the present invention, the present invention is limited to the above embodiments only. It should not be understood to be limited, and the scope of the present invention should be understood as the following claims and equivalent concepts.
