Description

전화기 스피커의 그릴 구조Grill structure of telephone speaker

본 발명은 전화기에 관한 것으로서, 특히 일반 전화기 및 키폰 전화기에 있어서 음의 명료도를 높이기 위한 스피커 그릴 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more particularly, to a speaker grill structure for improving sound clarity in a general telephone and a keypad telephone.

통상적으로, 일반 전화기 및 키폰 전화기에는 송신자로부터 전달된 음을 방출하기 위한 스피커가 장착된다. 상기 스피커에서 방출된 음은 전화기 하우징에 형성된 그릴을 통해 수신자의 귀에 전달된다.Typically, ordinary telephones and keypad telephones are equipped with speakers for emitting sound transmitted from the sender. The sound emitted from the speaker is transmitted to the receiver's ear through a grill formed in the telephone housing.

도 1은 종래 기술의 실시예에 따른 전화기 스피커의 그릴 구조를 나타낸 배면도이고, 도 2는 종래 기술의 실시예에 따른 스피커가 부착된 전화기 스피커의 그릴 구조를 나타낸 단면도이다.1 is a rear view illustrating a grille structure of a telephone speaker according to an exemplary embodiment of the prior art, and FIG. 2 is a cross-sectional view illustrating a grille structure of a telephone speaker with a speaker according to an exemplary embodiment of the prior art.

종래에는 도 1 및 도 2에 도시된 바와 같이 전화기 하우징(1)의 내측에는 다수개의 구멍(12)이 형성된 그릴(10)을 형성하고, 상기 그릴(10)의 내측에는 다수개의 체결품에 의해 하우징(1)의 부시에 고정된 스피커(20)가 장착된다. 상기 구멍 (12) 주위의 그릴(10) 부분은 평면으로 형성된다.In the related art, as illustrated in FIGS. 1 and 2, a grill 10 having a plurality of holes 12 is formed inside the phone housing 1, and a plurality of fasteners are formed inside the grill 10. The speaker 20 fixed to the bush of the housing 1 is mounted. The portion of the grille 10 around the hole 12 is formed in a plane.

상기 스피커(20)에서 방출된 음의 일부는 a와 같이 그릴에 형성된 구멍(12)을 통과하여 전화기 수신자의 귀로 전달되지만, 구멍을 통과하지 못한 음, 즉 그릴의 평면 부분에 부딪친 음은 b와 같이 다시 스피커(20) 쪽으로 반사된다.Some of the sound emitted from the speaker 20 passes through the hole 12 formed in the grill as in a, and is transmitted to the receiver of the telephone receiver. However, the sound that does not pass through the hole, that is, the sound hitting the flat portion of the grill is b and Likewise reflected back to the speaker 20.

상기와 같이 스피커 쪽으로 반사된 음은 스피커에서 새로 방출된 음과 부딪혀 간섭현상을 일으키게 되는데, 이러한 현상은 수신자가 느끼는 음의 명료도를 떨어뜨리게 되는 문제점이 있었다.As described above, the sound reflected toward the speaker collides with the newly emitted sound from the speaker, causing interference, and this phenomenon has a problem of degrading the clarity of the sound felt by the receiver.

상기와 같은 문제점을 해결하기 위하여 본 발명의 목적은 음의 명료도를 높이고, 음떨림·공명 등의 현상을 방지하기 위한 전화기 스피커의 그릴 구조를 제공하는데 있다.SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a grille structure of a telephone speaker for improving sound intelligibility and preventing phenomena such as shaking and resonance.

상기와 같은 목적을 달성하기 위하여 본 발명은 하우징과, 상기 하우징 내측에 형성한 그릴과, 상기 그릴의 내측에는 체결품에 의해 고정된 스피커가 장착된 전화기에 있어서, 상기 그릴은 다수개의 리브로 구성되고, 상기 리브는 내측으로 돌출한 나사산부와, 상기 나사산부의 일측에서 경사진 곡면을 이룬 곡면부를 연속으로 형성하고, 연속된 상기 나사산부와 곡면부 사이에는 그릴홀을 형성하는 것을 특징으로 한다.In order to achieve the above object, the present invention provides a housing, a grill formed on the inside of the housing, and a speaker mounted on the inside of the grill by a fastener, wherein the grill is composed of a plurality of ribs, The ribs may include a threaded portion protruding inwardly and a curved portion having a curved surface inclined from one side of the threaded portion, and a grill hole formed between the continuous threaded portion and the curved portion.

이하 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다. 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명을 생략한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, if it is determined that the detailed description of the related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

본 발명은 전화기에 관한 것으로서, 특히 일반 전화기 및 키폰 전화기에 있어서 음의 명료도를 높이기 위한 스피커 그릴 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone, and more particularly, to a speaker grill structure for improving sound clarity in a general telephone and a keypad telephone.

도 3은 본 발명의 바람직한 실시예에 따른 전화기 스피커의 그릴 구조를 나타낸 배면도이고, 도 4는 본 발명의 바람직한 실시예에 따른 스피커가 부착된 전화기 스피커의 그릴 구조를 나타낸 단면도이다.3 is a rear view illustrating a grille structure of a telephone speaker according to a preferred embodiment of the present invention, and FIG. 4 is a cross-sectional view illustrating a grille structure of a telephone speaker with a speaker according to a preferred embodiment of the present invention.

도 3 및 도 4에 도시된 바와 같이 본 발명의 그릴 구조는 다수개의 리브(30)로 형성된 그릴(10)과, 상기 그릴의 리브(30)는 내측으로 돌출한 나사산부(34)와, 상기 나사산부의 일측에서 경사진 곡면을 이룬 곡면부(32)를 연속으로 형성하고, 상기 나사산부와 곡면부를 형성한 리브(30)들 사이에는 그릴홀(36)을 형성한다. 상기 그릴의 내측에는 다수개의 체결품에 의해 하우징의 부시에 고정된 스피커(20)가 장착된다.3 and 4, the grill structure of the present invention includes a grill 10 formed of a plurality of ribs 30, the ribs 30 of the grills are threaded portions 34 protruding inward, and A curved surface portion 32 having a curved surface inclined at one side of the threaded portion is continuously formed, and a grill hole 36 is formed between the ribs 30 having the threaded portion and the curved portion. Inside the grille is mounted a speaker 20 fixed to the bush of the housing by a plurality of fasteners.

상기와 같이 형성된 그릴 구조를 통해 스피커의 음이 방출되면, 음의 일부는 c에 표시된 바와 같이 상기 그릴홀(36)을 통해 그릴을 통과하여 수신자의 귀에 전달된다. When the sound of the speaker is emitted through the grill structure formed as described above, part of the sound passes through the grill through the grill hole 36 and is transmitted to the receiver's ear as indicated by c.

반면, 상기 그릴홀을 통과하지 못하고 그릴홀 주변의 리브에 부딪힌 음은 d에 표시된 바와 같이 상기 리브(30)의 나사산부(34) 혹은 곡면부(32)에 부딪혀 반사된다. 이때, 상기와 같이 반사된 음은 나사산부와 곡면부의 경사도에 의해 스피커와 수직되는 방향으로 반사되지 않으므로, 새로 스피커에서 방출된 음과 직접 부딪히지 않는다.On the other hand, the sound hitting the ribs around the grill hole without passing through the grill hole is reflected by hitting the threaded portion 34 or the curved portion 32 of the rib 30 as indicated in d. At this time, the reflected sound as described above is not reflected in the direction perpendicular to the speaker by the inclination of the threaded portion and the curved portion, it does not directly hit the sound emitted from the new speaker.

즉, 상기와 같이 그릴홀을 통과하지 못한 음이 새로 방출되는 스피커의 음과 다른 방향으로 반사되므로, 음의 간섭이 일어나지 않는다.That is, as the sound that does not pass through the grill hole as described above is reflected in a direction different from the sound of the newly emitted speaker, the sound interference does not occur.

상술한 바와 같이 본 발명의 실시예에 따른 전화기 스피커의 그릴 구조는 방출된 음과 반사된 음간의 충돌을 방지하여 음의 명료도를 높이고 음의 공명·음떨림 현상을 방지할 수 있는 효과가 있다.As described above, the grille structure of the telephone speaker according to the embodiment of the present invention has an effect of preventing collision between the emitted sound and the reflected sound to increase the intelligibility of the sound and to prevent the resonance and the shaking of the sound.
