Abstract

PURPOSE: A headphone or an earphone is provided to reproduce a dynamic and live three dimensional sound by vibrating vigorously a permanent magnet, a yoke, and a planar diaphragm. CONSTITUTION: A headphone or an earphone includes a hollow fixed coil(4), a resonance tube(10), a planar diaphragm(1), and a body(6). The hollow fixed coil is buried in the body having a blocked bottom and adhered by using an adhesion material to form the resonance tube. A ventilation hole(13) is formed at a center of a yoke(2) and a permanent magnet(3) to form the integrated planar diaphragm. The planar diaphragm is assembled to the body to form a headphone unit. Two resonance tubes(10,12) are formed by assembling front and rear covers(8).

Description

헤드폰과 이어폰{HEADPHONE AND EARPHONE}Headphones and Earphones {HEADPHONE AND EARPHONE}

종래의 헤드폰이나 이어폰은 진동판이 돔형이며 보이스코일 진동방식으로 구성되어 있는데 멀티미디어 시대에 맞는 다이나믹하고 현장감 있는 입체음향이 요구되고 있으나 보이스코일 진동 방식으로는 다이나믹하고 현장감 있는 입체음향을 재생하기 어려운 문제점이 있다.Conventional headphone or earphone has a diaphragm dome type and is composed of voice coil vibration method, but dynamic and realistic stereo sound is required for the multimedia era, but voice coil vibration method is difficult to reproduce dynamic and realistic stereo sound. have.

본 발명은 멀티미디어 시대에 맞는 다이나믹하고 현장감 있는 입체음향을 청취할 수 있도록 음향 재생용 요크와 영구자석 진동방식의 평면형 진동판과 두 개의 공명통을 이용하여 다이나믹하고 현장감 있는 입체음향을 청취할 수 있는 헤드폰과이어폰을 제공하는데 목적이 있다.The present invention provides a headphone capable of listening to dynamic and realistic stereophonic sound by using a yoke for sound reproduction, a flat diaphragm with a permanent magnet oscillating method, and two resonance cylinders so as to listen to dynamic and realistic stereoscopic sound suitable for the multimedia era. The purpose is to provide earphones.

상기와 같은 목적을 달성하기 위하여 바람직한 실시 예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to achieve the above object, a preferred embodiment will be described in detail with reference to the accompanying drawings.

헤드폰과 이어폰은 크기가 다를뿐 구성과 용도가 동일하며 헤드폰과 이어폰은 통상 개방형과 밀폐형의 두 종류로 구분하는데 작용이 대동소이하므로 여기서는 밀폐형 헤드폰을 중심으로 설명한다.Headphones and earphones are different in size but have the same configuration and purpose. Since headphones and earphones are generally divided into two types, open and closed, the description will focus on sealed headphones.

도1은 종래의 헤드폰 유니트 측 단면도로서 몸체(6)의 밑면에 영구자석(3)과 요크(2)가 중공 리베트(18)에 의해 고정되고 통기공(7)이 있는 몸체(6)상부에 보이스코일(17)이 장착된 돔형의 진동판(1)이 조립되어 구성된다.1 is a cross-sectional side view of a conventional headphone unit, wherein a permanent magnet 3 and a yoke 2 are fixed to a bottom surface of a body 6 by a hollow rivet 18, and an upper portion of a body 6 having an air vent 7 therein. The dome-shaped diaphragm 1 to which the voice coil 17 was mounted is assembled.

도2는 본 발명의 헤드폰 유니트 측 단면도로서 밑면이 막히고 통기공(7)이 설치된 몸체(6)의 내부에 중공 고정코일(4)를 매립하고 접착제 등으로 고정시키고 상부의 중앙에 통기구(13)이 설치된 평면 진동판(1)의 중앙에 요크(2)와 영구자석(3)을 접착시킨 후 몸체(6)에 설치하여 구성된 헤드폰용 유니트이다.2 is a cross-sectional side view of the headphone unit of the present invention, a hollow fixing coil 4 is embedded in the inside of the body 6 in which the bottom surface is blocked and the vent hole 7 is installed and fixed with an adhesive or the like, and the vent hole 13 is disposed at the center of the upper portion. The yoke 2 and the permanent magnet 3 are adhered to the center of the installed flat diaphragm 1, and the head unit is configured by being installed on the body 6.

도3은 본 발명의 헤드폰 유니트 분해 사시도로서 (1)은 평면 진동판,(2)는 요크,(3)은 영구자석,(13)은 통기구,(4)는 고정코일,(5)는 연결선,(6)은 몸체,(7)은 통기공이다.3 is an exploded perspective view of a headphone unit according to the present invention, where 1 is a flat diaphragm, 2 is a yoke, 3 is a permanent magnet, 13 is a vent, 4 is a fixed coil, and 5 is a connecting line. (6) is the body, (7) is a vent.

도4는 본 발명의 헤드폰 유니트가 케이스에 장착하여 머리에 설치된 측 단면도로서 미도시된 음향재생기로 부터 전기신호가 연결선(5)를 통하여 인가되면 중공 고정코일(4)가 전자석의 역할을 하는 소레노이드로서 상하에서 위상변화에 따라 N극 혹은 S극으로 자극이 변화하면서 영구자석(3)을 밀거나 당기게 되며 영구자석(3)과 요크(2)와 평면 진동판(1)이 일체가 되어 있으므로 위상변화에 따라 N극 혹은 S극으로 자극이 변화하면서 영구자석(3)을 밀거나 당기게 될때 영구자석(3)과 요크(2)와 평면 진동판(1)이 동사에 진동을 하면서 소리를 재생시키게 된다.4 is a side cross-sectional view of a headphone unit of the present invention mounted on a case and a hollow fixing coil 4 serves as an electromagnet when an electric signal is applied through a connecting line 5 from an acoustic regenerator, not shown. As the magnetic pole changes the magnetic pole to the N pole or the S pole according to the phase change from the top and the bottom, the permanent magnet 3 is pushed or pulled, and the permanent magnet 3, the yoke 2, and the plane diaphragm 1 are integrally formed. When the magnetic pole is changed to the north pole or the south pole according to the change, when the permanent magnet (3) is pushed or pulled, the permanent magnet (3), the yoke (2), and the flat diaphragm (1) vibrate the verb to reproduce sound. .

소리를 듣기위하여 앞커버(8)에 설치된 밀착구(9)를 두부(14)에 밀착시키게 되면 밀착구(9)가 귀를 감싸고 덮게 되면서 평면 진동판(1)을 중심으로 앞부분의 귀구멍(15)와 고막(16)부분이 밀폐되는데 평면 진동판(1)이 진동을 하면 통기공(7)이 평면 진동판(1)의 진동을 어느 정도 완화시키는 역할은 하지만 완전하지 못하다.When the close contact (9) installed in the front cover (8) in close contact with the head 14 in order to hear the sound, the close contact (9) wraps and covers the ears and the ear hole (15) around the flat diaphragm (1). ) And the tympanic membrane 16 are sealed, but when the flat diaphragm 1 vibrates, the vent hole 7 mitigates the vibration of the flat diaphragm 1 to some extent but is not complete.

평면 진동판(1)이 진동을 하면 밀폐된 귀구멍(15)와 고막(16)사이의 공간의 공기가 압력을 받게 되고 이 압력이 평면 진동판(1)에 작용하여 평면 진동판(1)의 자유로운 진동을 방해하여 평면 진동판(1)이 앞으로 충분히 진동을 할 수 없으며 뒤커버(11)에는 진공압이 발생하여 평면 진동판(1)을 당기게 되므로 평면 진동판(1)의 자유로운 진동을 방해하여 평면 진동판(1)이 충분한 진동할 수 없게 되어 다이나막하고 현장감 있는 입체음향을 재생시키지 못하게 된다.When the flat diaphragm 1 vibrates, the air in the space between the sealed ear hole 15 and the eardrum 16 is pressurized, and this pressure acts on the flat diaphragm 1 to freely vibrate the flat diaphragm 1. The flat diaphragm 1 cannot vibrate sufficiently in the future, and a vacuum pressure is generated in the rear cover 11 to pull the flat diaphragm 1, thus preventing the free vibration of the flat diaphragm 1 so that the flat diaphragm 1 ) Cannot vibrate enough to reproduce a dynamic and realistic stereophonic sound.

본 발명은 이런 문제점을 해결하기 위하여 평면 진동판(1)과 영구자석(3)과 요크(2)의 중앙에 통기구(13)을 설치하여 밀페된 공기가 압력을 받거나 진공압을 받으면 통기구(13)을 통하여 공기가 자유로이 앞뒤로 이동되면서 진공압과 압력을 해소시켜 앞커버(8)와 뒤커버(11)의 공기압을 항상 상압으로 균형을 유지시켜 평면 진동판(1)이 자유롭게 진동하게 하고 평면 진동판(1)의 평면이 힘의 분산없이직선으로 귀구멍(15)를 지나 고막(16)에 진동이 전달되어 다이나믹하고 현장감 있는 입체음향을 듣게 되며 보다 더 효과를 높이기위하여 중공 고정코일(4)를 몸체(6)에 고정시키면 고정코일(4)의 중앙에 뚫린 구멍의 밑 부분이 몸체의 밑바닥에 밀착 고정되면 몸체(6)의 밑면이 고정코일(4)의 밑면을 막아 공명통(10)이 형성되고 앞커버(8)에 뒤커버(11)를 조립하면 자연스럽게 뒤커버(11)에 공명통(12)가 형성되어 두 개의 공명통을 가지게 되며 두 개의 공명통에 의해 더욱 다이나믹하고 현장감 있는 입체음향을 즐길 수 있게 된다.The present invention is installed in the center of the flat diaphragm 1, the permanent magnet (3) and the yoke (2) in order to solve this problem, the air vent (13) when the sealed air is subjected to pressure or vacuum pressure Air is freely moved back and forth through the vacuum pressure and pressure to relieve the air pressure of the front cover (8) and the rear cover (11) to always balance the normal pressure to the flat diaphragm (1) to vibrate freely and the flat diaphragm (1 ), The vibration of the plane is passed through the ear hole (15) in a straight line without dispersing the force to hear a dynamic and realistic stereoscopic sound, and to increase the effect of the hollow fixing coil (4) to the body ( 6) If the bottom of the hole drilled in the center of the fixing coil (4) tightly fixed to the bottom of the body when the bottom of the body (6) blocks the bottom of the fixing coil (4) to form a resonance tube (10) and the front Assemble the back cover 11 to the cover (8) Open resonating box 12 to the rear cover 11 is carefully formed to have the two resonating box, and it is possible to enjoy a stereo sound with more dynamic and realistic by two resonating box.

두 개의 공명통(10),(12)와 통기구(13)를 구비한 영구자석(3)과 요크(2)와 평면 진동판(1)의 박력있는 진동에 의해 다이나믹하고 현장감 있는 입체음향을 즐길 수 있는 효과가 있다.You can enjoy dynamic and realistic stereoscopic sound by powerful vibration of permanent magnet 3 and yoke 2 and flat diaphragm 1 with two resonance cylinders 10, 12 and vents 13 It works.
