본 발명은 전화기에 임의 부착하여 걸려온 전화말소리가 부착한 본 발명 장치를 통하여 확성되어 나오게함으로써 여러사람이 동시에 함께 전화를 들을 수 있도록 한것으로 먼저 본 구성요부인 회로에 대하여 실시예로 상술하면 다음과 같다.The present invention is to allow a number of people to listen to the phone at the same time by allowing the phone to be amplified through the present invention attached to the phone attached to the phone arbitrarily attached to the first embodiment of the circuit as described in the embodiment as follows. .

이하 본 발명에서 소리라함은 전화기 수화기로부터 들려오는 소리 또는 전화기에서 발하여지는 음파를 말하는 것으로 한다. 본 발명은 정음부(整音部), 조음부(調音部) 및 확성부등 3가지 부분의 결합에 의하여 구성된다.Hereinafter, in the present invention, the term "sound" refers to a sound heard from a telephone receiver or a sound wave emitted from a telephone. The present invention is constituted by a combination of three parts, namely, a silent part, an articulator part, and a loudspeaker part.

먼저 정음부는 픽업코일(P)로 전화기로부터 발하여지는 음파를 유기시켜 1 0㎌ 콘덴서(C2)를 경유하여 트랜지스터(TR1)의 베이스를 인가시키고, 픽업코일(P)에 병렬로 0.001㎌ 콘덴서(C1)를 연결시켜 접지시켜며, 트랜지스터(TR1)의 에미터에는 50㎌ 콘덴서 (C3)와 3.3KΩ 저항 (R2)를 병열 연결하여 접지시키며, 1MΩ저항(R1)을 트랜지스터(TR1)의 콜렉터에서 베이스에 접속시켜 바이어스를 주며, 10KΩ저항(R3)을 콜렉터에 연결시켜 구성한 것으로 콘덴서 (C1)은 잡음 제거용이며, 콘덴서(C2)는 직류저지용 이고, 콘덴서 (C3)는 교류분 제거용이며, 저항(R2)는 트랜지스터 (TR1)의 온도변화에 대한 안장을 주기위한 것이다. 이와 같이 구성된 정음부는 픽업코일을 통하여 유입된 음파에서 잡음을 제거한후 증폭하여 다음단의 조음부로 보낸다. 조음부는 정음부의 출력을 10㎌ 콘덴서 (C4),5KΩ의 볼륨 (VR), 10㎌ 콘덴서 (C5)를 거쳐 트랜지스터 (TR2)의베이스에 인가한다.First, the silent portion picks up the sound wave emitted from the telephone with the pick-up coil P, applies the base of the transistor TR 1 via a 10 kHz capacitor C 2 , and then 0.001 kHz capacitor in parallel with the pick-up coil P. (C 1) to the said connection to earth, a transistor (TR 1) the emitter is 50㎌ capacitor (C 3) and 3.3KΩ resistor (R 2) connected to the ground sikimyeo byeongyeol of a 1MΩ resistor (R 1) transistor The collector of (TR 1 ) is connected to the base for biasing, and the 10KΩ resistor (R 3 ) is connected to the collector. The capacitor (C 1 ) is for noise reduction, and the capacitor (C 2 ) is for DC blocking. Capacitor C 3 is for removing alternating current and resistor R 2 is intended to saddle the temperature change of transistor TR 1 . The static part configured as described above removes noise from the sound wave introduced through the pickup coil, amplifies it, and sends the amplified part to the next stage articulator. The articulation section applies the output of the quiet section to the base of the transistor TR 2 via a 10 kV capacitor (C 4 ), a volume of 5K kV (VR), and a 10 kV capacitor (C 5 ).

트랜지스터(TR2)의 에미터에는 50㎌ 콘덴서(C6)와 220Ω저항 (R4)을 병열 연결하여 접지시켰으며, 콜렉터와 베이스 사이에는 470Ω저항(R12)를 연결하여 베이스에 바이어스를 인가하여 주고 있으며 콜렉터에는 5.6KΩ저항(R5)를 연결하여 정음부의 저항(R3)과 같이 조음부에 전원을 공급하고 있다.The emitter of transistor (TR 2 ) is grounded by connecting 50 Ω capacitor (C 6 ) and 220 Ω resistor (R 4 ) in parallel, and connecting the 470 Ω resistor (R 12 ) between collector and base to apply bias to the base. to give, and the collector has to provide power to the vagina as crude 5.6KΩ resistor (R 5) resistance (R 3); quiet portion to connect.

여기서 콘덴서 (C4)와(C5)는 트랜지스터(TR1)과(TR2)의 결합내지 직류지지용 이다.Here, the capacitors C 4 and C 5 are for coupling or direct current support of the transistors TR 1 and TR 2 .

이와 같이 구성된 조음부는 정음부에서 인가된 음성파를 증폭시키고 잡음을 제거시킨후 확성부로 보내는데 확성부의 스피커에서 발하게되는 전화음성의 강약의 양호한 조절하기 위하여 5KΩ의 볼륨(VR)을 넣었다.The amplification unit configured as described above amplifies the sound wave applied from the silent part, removes the noise, and sends it to the loudspeaker. A volume (VR) of 5 KΩ has been put in order to adjust the strength of the telephone voice generated by the loudspeaker loudspeaker well.

다음 확성부는 조음부의 출력을 10㎌ 콘덴서(C7)를 통하여 트랜지스터(TR3)의 베이스에 인가시키고, 5KΩ 저항(R6)을 통하여 접지시키며, 트랜지스터(TR3)의 에미터는 50㎌ 콘덴서(C8)과 100Ω 저항(R8)을 병열로 하여 접지시키며, 콜렉터에서 베이스로 10KΩ 저항(R7)을 연결시켜 바이어스를 주었고, 출력측에는 트랜스(T)를 설치하여 2차측에 푸쉬풀로 트랜지스터(TR4)와 (TR5)를 구성함에 있어 그 중성점에는 9VCC의전원(A)을 1KΩ저항(R10)을경유하여 연결시킴과 동시에 100Ω저항(R9)를 통하여 접지시키고, 트랜지스터(TR4)와(TR5)의 베이스사이에는 0.005㎌ 콘덴서(C11)(C12)(C13)를 연결시켰으며, 에미터에는 2Ω공통저항(R11)을 경유하여 접지시키고, 트랜지스터(TR4)(TR5)의 공통콜렉터에 스피거(S.P)를 구성하며, 조음부의 콜렉터저항(R5)과 확성부의 출력트랜스(T)의 2차측전원사이에 220Ω저항(R12)과 저항(R12) 양단에 100㎌ 콘덴서(C9) 및 (C10)을 일단 접지하여 발진을 방지케함으로서 하울링 (Howling)을 제거하는 하울링 방지회로를 구성한 것으로 전화기의 음성을 증폭하여 스피커(SP) 통하여 울려나오게 한것이다.The amplification section then applies the output of the tuning section to the base of the transistor TR 3 through a 10 kV capacitor C 7 and grounds it via a 5K kΩ resistor R 6. The emitter of the transistor TR 3 is a 50 kV capacitor ( C 8 ) and 100 kΩ resistor (R 8 ) are grounded in parallel, biased by connecting a 10KΩ resistor (R 7 ) from the collector to the base, and a transformer (T) is installed on the output side and the transistor is pushed on the secondary side. In constructing (TR 4 ) and (TR 5 ), connect the power supply A of 9V CC to the neutral point through 1KΩ resistor (R 10 ) and ground it through 100Ω resistor (R 9 ) at the neutral point. 4 ) and a base of (TR 5 ) is connected with a 0.005 kV capacitor (C 11 ) (C 12 ) (C 13 ), the emitter is grounded via a 2 kΩ common resistor (R 11 ), and the transistor (TR) 4 ) A speaker (SP) is formed in the common collector of (TR 5 ), and the collector resistance (R 5 ) of the tuning section and the loudness section An output transformer (T) 2 side to the one end ground 100㎌ capacitor (C 9), and (C 10) across 220Ω resistor (R 12) and a resistance (R 12) between the power supply by Kane prevent oscillation of the feedback (Howling) It consists of a howling prevention circuit that removes the amplified voice of the phone is to ring through the speaker (SP).

본 발명에서 사용한 트랜지스터(TR1)(TR2)(TR3)는 각각 2SC 372형이고, 트랜지스터(TR4)(TR5)는 2SC 735형이다. 조음부는 정음부에서 픽업하여 어느정도 증폭한 음파를 더욱 증폭시킴과 동시에 보륨(VR)에 의하여 증폭의 크기를 조절할 수 있도록 하는 역할을 한다.The transistors TR 1 (TR 2 ) (TR 3 ) used in the present invention are each 2SC 372 type, and the transistors TR 4 (TR 5 ) are 2SC 735 type. The articulation unit amplifies the sound wave amplified to some extent by picking it up from the silent unit and at the same time plays a role of controlling the amplitude of the amplification by the volume (VR).

확성부는 공지의 증폭회로와 동일하며 조음부에서 적당한 크기로 증폭된 음을 확성시키는 역할을 하게 된다. 상기와 같이 구성된 회로를 가진 장치는 스피이커(SP)가 전화기 표면쪽에 근접되도록 부착시켜야 한다는 것이다. 그렇지 않으면 하울링(Howling)즉 스피이커에서 나오는 음성이 다시 픽업코일(P)로 유도되어 들어가서 발전을 이르켜 잡음을 발생하게 되기 때문이다.The loudspeaker is the same as the known amplification circuit and plays a role of amplifying the sound amplified to an appropriate size in the articulator. A device with a circuit configured as described above requires that the speaker SP be attached close to the phone surface. If not, howling, or voice from the speaker, is guided back to the pick-up coil (P), which leads to power generation and generates noise.

따라서 본 발명에서는 하울링을 방지하기 위하여 하울링방지 회로를 구성하고 있다.Therefore, in the present invention, the howling prevention circuit is configured to prevent the howling.

이상과 같이 본 발명에 의한 확성장치를 전화기의 임의의 위치(가장 바람직하기는 다이얼과 반대폭 위치)에 부착시키면 정음부에서 픽업된 전화 수화음파중 잡음이 제거되어 맑아지고 어느 정도 증폭된 음파는 조음부에서 더욱 증폭되게 하여 공지의 확성부로 전달하여 소리가 확대되어 나오도록 하되, 이때 조음부의 보륨(VR)을 조절하여 확성되는 말소리의 강약을 원하는대로 조절할 수가 있다.As described above, when the loudspeaker according to the present invention is attached to an arbitrary position of the telephone (most preferably opposite to the dial), the noise of the telephone picked-up sound picked up from the silent part is removed, and the sound wave amplified to some extent is removed. It is further amplified in the articulation section to transmit the sound to the known amplification section to expand the sound, at this time by adjusting the volume (VR) of the articulation section can be adjusted to the intensity of the speech sound as desired.

따라서 본 발명 확성장치에 의하면 한개의 전화기에서 들여오는 수화부의 말소리를 전화기 주변에 모인 여러사람이 동시에 함게 들을수 있도록 확성시킬수가 있게 된다.Therefore, according to the present invention amplification device, it is possible to amplify the sound of the receiver of a telephone received from one telephone so that several people gathered around the telephone can be heard at the same time.

본 발명의 각 부분의 수치는 전체면에서 비례적으로 증감시켜서 실시할 수 있다.The numerical value of each part of this invention can be implemented by increasing and decreasing proportionately in the whole surface.
