Description

  The present invention relates to a kind of earphone, and more particularly, to an earphone capable of adjusting a low frequency sound.

  Articulated earphones are greatly appreciated by people because of their excellent portability, high-quality voice expression, and excellent sound separation effects.

  However, there is no articulator for well-adjustable earphones, and the adjustment of the sound volume and sound quality effect is realized by adjustment control by the playback equipment, and the earphone itself controls the sound volume and sound quality effect. The sound quality effect of the earphone is completely limited by the quality of the playback equipment and the quality of the earphone, and one earphone can provide only one kind of tone and frequency response characteristics, that is, one kind of auditory sensation However, for general consumers, if the entertainment is not enough, and if they want to have various types of auditory sensations, it is necessary to purchase several types of earphones, which increases the cost of use.

  This provides a kind of tuneable earphone with adjustable low frequency sound that allows consumers to adjust to their desired bass characteristics based on their personal preference and music characteristics, without having to purchase various earphones separately It is necessary to be able to enjoy different auditory sensations.

  An object of the present invention is to provide a kind of low-frequency sound-adjustable earphone that can cope with the above-described lack of known technology.

  In order to achieve the above-described object, the tuneable earphone of the present invention includes a front chamber, a tuning body, a rear chamber, and a speaker unit mounted in the front chamber and the rear chamber, and the front chamber includes a sound output cylinder. And the rear end of the sound generating cylinder projects outward along the radial direction to form a closed cover, and the side edge of the closed cover is vertically extended rearward to form a closed cylinder. An open groove that has a circular shape is opened on one side of the front surface of the chamber, a tuning hole that penetrates the close cover is opened in the bottom wall of the open groove, and a leak hole that communicates with the tuning hole is opened in the closed cylinder of the front chamber . The above-described articulator is rotatably attached to the front chamber and includes a base block having a columnar shape. An articulation column having a cross-sectional area smaller than the base block is extended behind the rear surface of the base block, and one of the articulation columns. On the side, a notch corresponding to the leak hole is formed inwardly. The rear chamber and the front chamber are connected in combination with each other, and the speaker unit is accommodated in a chamber formed by combining the front chamber and the rear chamber.

  As described above, the tuneable earphone of the present invention is attached to the front chamber so that the tuned body can rotate, and the relative position between the notch and the air leakage hole is adjusted by the rotation of the tuned body, thereby producing a low sound output. Controls the volume and flow velocity, thereby changing the low frequency response curve of the bass, thereby obtaining a different auditory sensation.

It is a three-dimensional view of an earphone capable of articulation of the present invention. FIG. 3 is a three-dimensional exploded view of the tuneable earphone of FIG. 1. It is the three-dimensional exploded view from another angle of the earphone which can be tuned of FIG. FIG. 3 is a three-dimensional view of the articulator of the articulated earphone of FIG. 1. It is a frequency response curve figure of a different state at the time of use of the earphone which can be tuned of FIG.

  In order to describe in detail the technical contents, structural features, and objects to be achieved of the present invention, examples will be described below in combination with the drawings.

  Please refer to FIG. 1 and FIG. The tuneable earphone 100 of the present invention includes a front chamber 10, a rear chamber 30, a speaker unit 40, a sound adjuster 20, and a handle 50. Among them, the front chamber 10 and the rear chamber 30 are combined and connected to each other so as to surround and form the chamber (not shown). The speaker unit 40 is accommodated in the chamber, a sound chamber (not indicated) is formed between the front chamber 10, the rear chamber 30, and the speaker unit 40, and the sound adjusting body 20 is rotatably attached to the front chamber 10.

  Please refer to FIG. 1, FIG. 2 and FIG. The aforementioned front chamber 10 includes a sound output cylinder 11 having a hollow structure, and a close cover 12 is formed at the rear end of the sound output cylinder 11 so as to protrude outward along the radial direction thereof. Then, the side edge of the close cover 12 is vertically extended backward to form the closed cylinder 13. An open groove 141 having a circular shape is formed on one side of the front surface of the close cover 12, and a movable groove 142 having a fan shape is extended outward from the outer groove wall of the open groove 141, and is movable with the open groove 141. The groove 142 communicates, and a sound adjustment hole 143 that penetrates the close cover 12 is further provided in the groove bottom wall of the open groove 141, and the diameter of the sound adjustment hole 143 is smaller than the diameter of the open groove 141. A locking base (not shown) is formed between the connecting portions of the sound adjustment holes 143, and a leak hole 15 communicating with the sound adjustment hole 143 is further opened in the closed cylinder 13 of the front chamber 10.

  Please refer to FIG. 1, FIG. 2 and FIG. The above-described articulator 20 includes a base block 21 having a columnar shape. A rotation groove 211 is formed on the front surface of the base block 21, and a position limiting block 212 projects outwardly on one side of the base block 21. A sound-adjusting column 22 whose cross-sectional area is smaller than the base block 21 is extended behind the rear surface of the base block 21, and an inward notch 221 is provided on one side of the sound-adjusting column 22 so as to correspond to the leak hole 15. It is done. The tuning column 22 of the tuning body 20 is inserted into the tuning hole 143, the base block 21 is housed in the open groove 141 and locked to the locking base, the position limiting block 212 is stored in the movable groove 142, and The position limiting block 212 is rotatable between the groove walls on both sides of the movable groove 142.

  Please refer to FIG. 1, FIG. 2 and FIG. The rear chamber 30 described above has a hollow structure, and a mounting hole 31 penetrating the hollow structure of the rear chamber is provided at the bottom of the rear chamber 30, and the handle 50 is mounted in the mounting hole 31.

  Please refer to FIG. In this figure, the relative position of the notch 221 and the leak hole 15 is adjusted by rotating the articulator 20 after the assembly of the earphone 100 capable of articulation is completed within the frequency range (20 Hz to 20 KHz) of the human ear. Thus, it can be shown that the purpose of controlling the outflow volume and flow velocity of the gas in the sound chamber can be achieved, thereby producing a reflection of different bass frequency response curves, thereby creating different auditory sensations. Specifically, when the tuning body 20 is rotated so that the notch 221 is not in communication with the leak hole 15, that is, when the notch 221 is completely closed, the pressure in the sound chamber is maximized and the bass is strongest, and the frequency response curve of the bass is It is represented by curve III in the figure. If the notch 221 and the leak hole 15 are completely communicated by rotating the articulator 20, the pressure in the sound chamber is minimized and the bass is weakest, and the frequency response curve of the bass is shown by the curve I in the figure. . When the notch 221 and the leak hole 15 do not completely correspond to each other, the frequency response curve of the bass is indicated by the curve II in the figure.

  As described above, the tuneable earphone 100 of the present invention is attached to the front chamber 10 so that the tuned body 20 is rotatable, and the relative position of the notch 221 and the leak hole 15 is adjusted by the rotation of the tuned body 20. Thus, it is possible to control the volume and flow velocity of the bass and thereby change the low frequency response curve of the bass, thereby obtaining a different auditory sensation.
