Earphone is an abbreviation of earphone receiver, and it is generally divided into crystal receiver which uses piezoelectric effect of crystal element and magnetic receiver which operates the diaphragm by flowing voice current to voice coil and does not disturb others. It is a device implemented to listen to the various sounds output from the other sound generating terminal, etc. is formed in the form of being inserted into the ear hole of the user for easy portability and smooth audio output.

The general structure of the earphone is a circuit board coupled to the wire and soldering method is formed inside the case constituting the main body of the earphone, the speaker unit for outputting sound by vibration of the vibration plate is coupled to the upper portion of the circuit board, the vibration plate The upper surface of the diaphragm for protecting the diaphragm is made in a manner that is coupled by a ring-shaped clip.

In addition, the currently popular kernel-type earphone is also referred to as a sealed earphone, the ear coupler has a protruding shape, so the ear coupler is deeply worn in the user's ear has the characteristics of good sound insulation.

Currently, earphones with a wide variety of types and functions are on the market, but the factors that can determine the quality of these earphones vary, but most of all, it is determined by whether the design is excellent and the comfort is comfortable. Could be.

However, the earphone structure of the current electrode soldering method has a disadvantage in that the cable connected to the electrode is easily disconnected and the cable is not easy to connect and repair after disconnection, and the speaker unit and the cable are integrally connected by soldering. As a result, there was a problem that the case could not be easily exchanged, which could lead to various designs because the case was completely fixed to the speaker unit.

In addition, since the expression of the bass region frequency and the bass region frequency in the diaphragm are often expressed in an inverted phase in which the diaphragm frequency is expressed up and down on the basis of one diaphragm, the acoustic loss due to the acoustic cancellation is large and the sound quality is lowered.

The positive and negative electrode patterns 86 and 87 of the third electrode terminal 85 may also be pole-set in a manner similar to that of the first terminal, and may further include a through hole 88 to ensure an electrode connection relationship.

The contact relationship between the second and third electrode terminals 62 and 85 is not shown in the drawings to ensure contactability if the third electrode terminal 85 does not need to be replaced while the earphone is in use. It is also possible to take a method of fixed close contact with each other by fastening fasteners around the electrode terminals 62 and 85.

15 is an exemplary view illustrating a user wearing state and air flow of the earphone assembly according to the present invention, and FIG. 16 is a graph of frequency characteristics that change according to the degree of opening of the acoustic leak holes 36 and 42 according to the present invention.

Referring to Figure 15, the user can see the progress of the air and sound through the arrow sign in a state wearing the earphone assembly according to the present invention.

In the speaker unit 100, the sound traveling in the direction of the user's ear is partially emitted to the outside through the first and second acoustic leak holes 42 and 36 formed at the ear entry inlet. The emitted sound proceeds toward the outside and then flows into the third through hole 173 of the frame 130 or the through hole 203 of the resonance housing 200.

In other words, the air flow in the acoustic leak holes 36 and 42 and the third through hole 173 (through hole of the resonant housing) are in opposite directions, i.e., in reverse phase, so that a part of the sound flowing out of the ear is separated. It can be canceled out and destroyed naturally without relying on circuit signal processing. Therefore, due to the action of the acoustic leakage holes 36 and 42 and the third through hole (through hole) of the reverse phase relationship, the noise transmitted to the surroundings is significantly reduced compared to the conventional earphones even while listening to high volume music. do.

In addition, the acoustic leakage holes 36 and 42 are easily opened by the rotation of the front head 30, and thus the acoustic leakage holes 36 and 42 may be easily manipulated. Referring to FIG. It can be seen that the acoustic energy of the bass region decreases when the opening is partially open and fully closed than when it is fully open. Through this graph, the opening state of the acoustic leakage holes 36 and 42 is adjusted. It can be inferred that the intensity of energy can be controlled.

That is, the acoustic leak holes 36 and 42 provide a dual function that not only acts as an external noise suppressor but also adjusts the thrust and intensity of the bass.

2) It is possible to prevent the cable twist and freely set the cable position by guaranteeing the 360 ° rotation of the electrode coupling unit.

3) With the 360 ° rotation of the front head, the opening and closing of acoustic leak holes can be controlled to significantly reduce the occurrence of noise to the outside, and the frequency energy of the bass region can be adjusted according to the user's preference.

4) The bass region is inverted and released in the same phase, so that the loss of the bass can be greatly reduced, resulting in more powerful bass.

5) Due to the ease of replacement of the detachable coupler and other components, the earphone can be transformed into various designs and colors at the same time,

6) Due to the provision of flexible electrode elements, smooth and stable connection can be achieved even with the rotation of the unit.
