Abstract

A speaker is provided to prevent a coupling force of a bolt from being weakened due to vibration by absorbing the vibration generated when reproducing the sound. A speaker includes a housing(110), a base(120), and an elastic unit(130). The housing includes a protruded boss. The penetration hole is formed so that the boss penetrates the base. A sound unit is mounted in the center of the base. The elastic unit is mounted on the boss in contact with the base. The fixing unit is formed in the end part of the boss. The fixing unit is larger than the outer circumference of the elastic unit so that the elastic unit is not separated.

Description

스피커{SPEAKER}Speaker {SPEAKER}

본 발명은 스피커에 관한 것으로, 보다 상세하게는 음향 재생시에 발생되는 진동을 흡수하여 스피커를 안정하게 하며, 하우징과 베이스의 체결이 수평하게 유지될 수 있는 스피커에 관한 것이다.The present invention relates to a speaker, and more particularly, to a speaker that absorbs vibrations generated during sound reproduction to stabilize a speaker and to which the fastening of the housing and the base can be maintained horizontally.

스피커는 음향재생기로 영상표시장치, 오디오, 핸드폰과 같은 다양한 전자제품에 적용되어 음향을 재생시키는데 이용된다. 스피커는 자기력 및 진동을 통하여 음향이 재생되는 장치로서, 음향 재생시 진동이 발생되어 스피커 전체로 진동이 전달된다.The speaker is a sound player, and is applied to various electronic products such as a video display device, audio, and a mobile phone to reproduce sound. The speaker is a device in which sound is reproduced through magnetic force and vibration, and vibration is generated during sound reproduction, and vibration is transmitted to the entire speaker.

이러한 스피커는 외관을 형성하는 직육면체 형상의 하우징 내측으로 자기력 및 진동을 발생시키는 음향부 및 음향부를 지지하는 베이스가 구비된다. 하우징의 내측에는 보스가 돌출형성되며, 보스에 베이스가 체결된다.Such a speaker is provided with an acoustic part for generating magnetic force and vibration and a base for supporting the acoustic part inside a rectangular-shaped housing forming an external appearance. A boss protrudes inside the housing, and the base is fastened to the boss.

음향부를 지지하는 베이스는 음향 재생시에 음향부의 진동이 전달되는 하우징의 내측에서 흔들리게 되어 강성의 재질로 형성되는 베이스와 하우징은 부딪히게 되어 소음이 발생하게 된다. 또한, 하우징이 네 모서리에 설치되는 베이스는 조립과정에서 수평하게 설치되지 않는 경우가 종종 발생된다. 따라서, 이를 개선할 필요성이 요청된다.The base supporting the sound unit is shaken inside the housing through which the vibration of the sound unit is transmitted during sound reproduction, so that the base and the housing formed of the rigid material collide with each other to generate noise. In addition, the base in which the housing is installed at four corners is often not installed horizontally during the assembly process. Therefore, there is a need for improvement.

본 발명은 상기와 같은 필요성에 의해 창출된 것으로서, 베이스의 진동을 흡수하여 소음을 감소시킬 수 있는 스피커를 제공하는 데 그 목적이 있다. 또한, 본 발명은 조립시 발생되는 조립공수 오차를 감소시킬 수 있는 스피커를 제공하는 데 그 목적이 있다.The present invention has been made by the necessity as described above, an object of the present invention to provide a speaker that can reduce the noise by absorbing the vibration of the base. In addition, an object of the present invention is to provide a speaker that can reduce the assembly labor error generated during assembly.

본 발명에 따른 스피커는: 돌출형성되는 보스를 구비하는 하우징; 상기 보스가 관통되도록 관통홀이 형성되며, 중앙부에는 음향부가 장착되는 베이스; 상기 베이스와 맞닿도록 상기 보스에 장착되는 탄성부; 및 상기 보스의 단부에는 상기 탄성부가 이탈되지 않도록 상기 탄성부의 외주면보다 크게 형성되는 고정부를 포함한다.A speaker according to the present invention comprises: a housing having a boss formed thereon; A base having a through hole formed to penetrate the boss, and having a sound unit mounted at a center thereof; An elastic part mounted to the boss to be in contact with the base; And a fixing part formed at an end of the boss to be larger than an outer circumferential surface of the elastic part so that the elastic part is not separated.

바람직하게는, 상기 고정부는 외주면에 나사산이 형성되는 볼트로 이루어지며, 상기 보스 단부의 내주면에는 상기 볼트가 용이하게 결합되도록 나사산이 형성 된다.Preferably, the fixing part is made of a bolt formed with a screw thread on the outer peripheral surface, the screw thread is formed on the inner peripheral surface of the boss end so that the bolt is easily coupled.

바람직하게는, 상기 탄성부는, 상기 베이스와 상기 고정부에 맞닿도록 장착되는 제1탄성부와, 상기 베이스와 상기 하우징에 맞닿도록 장착되는 제2탄성부가 구비된다.Preferably, the elastic portion is provided with a first elastic portion mounted to abut the base and the fixed portion, and a second elastic portion mounted to abut the base and the housing.

본 발명에 따른 스피커는 종래 발명과 달리, 음향 재생시 발생되는 진동을 흡수하여 진동에 의해 볼트의 체결력이 점차 약해지는 것을 방지할 수 있으며, 스피커를 안정하게 할 수 있다.Unlike the conventional invention, the speaker according to the present invention absorbs the vibration generated during sound reproduction, thereby preventing the fastening force of the bolt from being gradually weakened by the vibration and making the speaker stable.

또한, 본 발명은 하우징과 베이스의 체결이 탄성부에 의해 수평하게 구비되므로, 조립공수의 오차를 줄일 수 있다.In addition, the present invention, since the fastening of the housing and the base is provided horizontally by the elastic portion, it is possible to reduce the error of assembly labor.

이하, 첨부된 도면들을 참조하여 본 발명에 따른 스피커의 일 실시예를 설명한다. 이 과정에서 도면에 도시된 선들의 두께나 구성요소의 크기 등은 설명의 명료성과 편의상 과장되게 도시되어 있을 수 있다. 또한, 후술되는 용어들은 본 발명에서의 기능을 고려하여 정의된 용어들로서 이는 사용자, 운용자의 의도 또는 관례에 따라 달라질 수 있다. 그러므로, 이러한 용어들에 대한 정의는 본 명세서 전반에 걸친 내용을 토대로 내려져야 할 것이다.

The boss 111 has a coupling groove in which a thread is formed on the inner circumferential surface in the shape of a cylinder, so that the fixing portion B is fastened.

베이스(120)는 보스(111)에 대응되어 모서리에 관통홀이 형성되며, 보스(111)의 외주면과 관통홀의 둘레면이 맞닿는다. 베이스(120)의 중앙부에는 우퍼 등의 음향부가 장착되어, 베이스(120)가 음향부를 지지한다.The base 120 corresponds to the boss 111, and a through hole is formed at an edge thereof, and the outer circumferential surface of the boss 111 and the circumferential surface of the through hole contact each other. A sound unit such as a woofer is mounted at the center of the base 120, and the base 120 supports the sound unit.

탄성부(130)는 스프링이며, 제1탄성부(131)와 제2탄성부(132)를 구비하고, 제1탄성부(131)와 제2탄성부(132)는 베이스(120)에 맞닿아 베이스(120)를 탄성지지하도록 보스(111)에 삽입된다.The elastic part 130 is a spring and includes a first elastic part 131 and a second elastic part 132, and the first elastic part 131 and the second elastic part 132 fit the base 120. The base 120 is inserted into the boss 111 so as to elastically support the base 120.

제2탄성부(132)가 베이스(120)의 좌측면과 하우징(110)의 우측면에 맞닿도록 보스(111)에 삽입되고, 제1탄성부(131)가 베이스(120) 우측면과 고정부(B)의 좌측면에 맞닿도록 보스(111)에 삽입된다. 고정부(B)는 제1탄성부(131)가 이탈되지 않도록 제1탄성부(131)의 외주면보다 크게 형성되며, 볼트로 이루어진다.The second elastic portion 132 is inserted into the boss 111 to abut the left side of the base 120 and the right side of the housing 110, and the first elastic portion 131 is fixed to the right side of the base 120 and the fixing portion ( It is inserted into the boss 111 to abut on the left side of B). The fixing portion B is formed to be larger than the outer circumferential surface of the first elastic portion 131 so that the first elastic portion 131 is not separated and is formed of a bolt.

이와 같이, 보스(111)의 외주면으로 제2탄성부(132)와 베이스(120)와 제1탄 성부(131)가 삽입되고 보스(111)의 단부로 고정부(B)가 체결된다. 제1탄성부(131)와 제2탄성부(132)는 베이스(120)의 좌우측에 구비되어, 베이스(120)의 좌우 흔들림에 의한 진동을 흡수한다. 또한, 베이스(120)의 네 모서리에 탄성부(130)가 구비되므로, 베이스(120)와 보스(111)의 체결이 수평하게 유지된다.As such, the second elastic portion 132, the base 120, and the first elastic portion 131 are inserted into the outer circumferential surface of the boss 111, and the fixing portion B is fastened to the end of the boss 111. The first elastic portion 131 and the second elastic portion 132 are provided on the left and right sides of the base 120 to absorb vibrations caused by the left and right shake of the base 120. In addition, since the elastic part 130 is provided at four corners of the base 120, the fastening of the base 120 and the boss 111 is horizontally maintained.
