본 발명은 첨부 도면 도 1 및 도 2에서 보는 바와 같이, 전자음향변환기(100)에 있어서, 마그네트(40)가 안착되는 면의 둘레에 외부 공기가 유입될 수 있도록 다수개의 유입구멍(11)이 형성된 요크(10)와, 중앙에 요크(10)가 삽입 가능하도록 통공(21)을 형성하되, 하향 돌출 삽입되는 요크(10)의 외주면을 지지할 수 있도록 통공(21)으로부터 하향 연장 형성된 환형돌부(22)와, 통공(21)의 외곽면 소정위치에 요크(10)의 유입구멍(11)으로부터 유입된 공기가 반대측으로 유출될 수 있도록 관통 형성된 유도구멍(23)과, 유도구멍(23)이 형성된 부분의 외주면에 소정의 넓이로 연장 돌출되면서 중앙에 유출구멍(24)이 수직 관통 형성된 연장돌부(25)와, 하부면 둘레의 내측으로 끼움턱(26)이 형성된 케이스(20)와, 케이스(20)의 끼움턱(26)에 상단이 끼움 결합되고, 하부면에 형성된 통공(31)에 케이스(20)의 환형돌부(22)가 끼워지면서 공명공간(S)이 형성되는 함체 형상의 캐비닛(30)이 구비되어서 구성됨을 특징으로 한다.1 and 2, in the electroacoustic transducer 100, a plurality of inlet holes 11 are provided to allow external air to flow around a surface on which the magnet 40 is seated. The formed yoke 10 and the annular protrusion formed downwardly from the through-hole 21 so as to support the outer circumferential surface of the yoke 10 to be inserted downward protruding into the yoke 10 to be inserted into the center (22), guide holes (23) formed therethrough so that air introduced from the inlet hole (11) of the yoke (10) can be discharged to the opposite side at a predetermined position on the outer surface of the through hole (21), and the guide hole (23). An extension protrusion 25 having an outlet hole 24 vertically penetrating through the outer peripheral surface of the formed portion and having a predetermined width, and a case 20 having a fitting jaw 26 formed around the lower surface thereof; The upper end is fitted to the fitting jaw 26 of the case 20, formed on the lower surface A through hole (31) characterized by the annular protrusion 22 is fitted As resonance space (S) it is be provided with a cabinet 30 of the housing shape is formed composed of the case 20.

상기 연장돌부(25)가 형성된 케이스(20)의 반대방향에는 코일(61)의 단선(61')과 외부 배선이 납땜 연결되도록 하는 터미널 패드(80)가 고정될 수 있도록 돌출면(27)이 일체로 형성되어 있다. In the opposite direction of the case 20 in which the extension protrusions 25 are formed, the protruding surface 27 may be fixed so that the terminal pad 80, which allows the disconnection 61 ′ of the coil 61 and the external wiring to be soldered thereto, may be fixed. It is formed integrally.

이와 같이 구성된 본 발명은 진동체나 전기 진동 회로 등에 고유 진동수와 동일한 진동을 외부로부터 가했을 때, 큰 진폭으로 진동하는 공명현상을 이용하여 전자음향변환기(100)의 저음특성을 향상시키도록 한 것이다.The present invention configured as described above improves the bass characteristics of the electroacoustic transducer 100 by using a resonance phenomenon that vibrates with a large amplitude when external vibrations, such as natural frequencies, are applied to a vibrating body or an electric vibration circuit.

즉, 전술한 바와 같이, 외부로부터 전류가 공급되어 코일(61)에 전류가 흐르게 되면 마그네트(40)와의 상호관계에 의해 자기력선이 발생되고, 코일(61)에 흐르는 전류의 방향과 해당 주파수의 진동수에 의해 코일(61)의 상부에 고정된 진동판(60)이 상, 하로 진동하면서 음향으로 변환되어 일부는 덮개(70)의 구멍(71)으로 출력됨과 동시에, 일부는 유도구멍(23)을 통해 공명공간(S)으로 인입되어 큰 진폭으로 진동하여 유출구멍(24)을 통해 유입된 공기와 함께 배출되게 된다.That is, as described above, when a current is supplied from the outside and the current flows in the coil 61, a magnetic force line is generated by the mutual relationship with the magnet 40, and the direction of the current flowing through the coil 61 and the frequency of the corresponding frequency. By vibrating the vibration plate 60 fixed to the upper portion of the coil 61 by the upper and lower, the sound is converted into a sound, and a part is output to the hole 71 of the cover 70, while at the same time a part through the guide hole 23 Into the resonance space (S) is vibrated with a large amplitude is discharged with the air introduced through the outlet hole (24).

상기 외부공기는 진동판(60)이 상, 하로 진동하게 되면 요크(10)의 유입구멍(11)을 통해 외부공기가 유입되었다가 케이스(20)의 유도구멍(23)을 통해 공명공간(S)으로 유입된 후 유출구멍(24)을 통해 외부로 배출되게 된다.When the diaphragm 60 vibrates up and down, the outside air is introduced through the inflow hole 11 of the yoke 10 and the resonance space S is introduced through the induction hole 23 of the case 20. After being introduced into, it is discharged to the outside through the outlet hole 24.

이때, 유입된 외부공기는 진동판(60)으로부터 발생된 진동파가 공명공간(S) 내에서 보다 큰 진폭으로 진동할 수 있도록 하는 공명 매개체가 되는 것이다.At this time, the introduced external air is a resonance medium that allows the vibration wave generated from the diaphragm 60 to vibrate with a larger amplitude in the resonance space (S).

참고로, 저음특성은 공명공간(S)의 체적에 비례해서 향상되며, 또한, 유출구멍(24)의 직경(면적) 및 길이가 길면 저음특성이 향상된다. For reference, the bass characteristic is improved in proportion to the volume of the resonance space S, and the bass characteristic is improved when the diameter (area) and the length of the outlet hole 24 are long.

미설명 부호 50은 탑플레이트이다. Reference numeral 50 is a top plate.

이와 같이 되는 본 발명은 전자음향변환기의 하부면에 공명공간이 형성되도록 캐비닛을 부설하되, 전자음향변환기 내부로 외부의 공기가 원활히 공급되고 진동하여 외부로 유출될 수 있도록 함으로써, 저음의 출력 특성이 향상되는 효과를 갖는다. In the present invention as described above, the cabinet is installed so that the resonance space is formed on the lower surface of the electroacoustic transducer, so that the outside air is smoothly supplied to the inside of the electroacoustic transducer and vibrates so that it can flow out to the outside, so Has the effect of improving.
