On the other hand, while the MP3 player is operated by the keys constituting the mobile phone, the contents of the call can be recorded by the MMC constituting the MP3 player.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 고안에 따른 휴대폰에 MP3 플레이어가 접속되는 구조를 설명하기 위해 개략 도시한 분리사시도로써, 본 고안은 도면에 도시된 것과 같이, 일측에 LCD(1)가 부착되고, 하부에는 접속단자(2)를 갖춘 휴대폰케이스(3)가 구비되고, 상부에 커넥터(4)가 돌출형성된 MP3 플레이어(5)가 구비되어, 상기 접속단자(2)에 커넥터(4)를 끼워주므로써 휴대폰(6)에 MP3 플레이어(5)가 연결설치되도록 구성되어 있다.1 is an exploded perspective view schematically illustrating a structure in which an MP3 player is connected to a mobile phone according to the present invention. As shown in the drawing, the present invention has an LCD 1 attached to one side and a connection terminal at the bottom thereof. A mobile phone case 3 having a mobile phone case 3 is provided, and an MP3 player 5 having a connector 4 protruding therefrom is provided, and the mobile phone 6 is inserted by inserting the connector 4 into the connection terminal 2. MP3 player 5 is configured to be connected to the installation.
그리고, 상기 휴대폰(6)에는 MP3 플레이어(5)를 구동하는 소프트웨어 및, MP3 플레이어(5)용 오디오 라인이 추가로 구성되고, 상기 MP3 플레이어(5)에는 MP3 파일 신호를 아날로그 신호 즉, 음악으로 변환시키는 회로인 DAC(7)와, 내부에 플래쉬 메모리칩(Flash Memory Chip)을 내장하고 있어 데이터를 저장할 수 있는 메모리 카드인 멀티 미디어 카드(MMC;Multi Media Cards:8) 및, 압축된 엠펙 레이어3 파일을 자동으로 해독하는 회로인 디코더(9;Decoder)가 전기적으로 연결구성되어 있다.The mobile phone 6 further includes software for driving the MP3 player 5 and an audio line for the MP3 player 5, and the MP3 player 5 converts the MP3 file signal into an analog signal, that is, music. Multi-Media Cards (MMC: 8), which are memory cards that can store data by incorporating a DAC (7), which is a circuit to be converted, and a flash memory chip, and a compressed MPEG layer. Decoder 9, which is a circuit for automatically decoding 3 files, is electrically connected.
따라서, 상기 접속단자(2)에 커넥터(4)를 끼워 휴대폰(6)에 MP3 플레이어(5)를 접속한 다음 도 2에 개략적으로 도시된 것과 같이 휴대폰(6)을 구성하고 있는 키이(10)를 통해 MP3 플레이어(5)를 작동시키는데에 필요한 기능을 MCU(11)로 전달 (A)하면, LCD(1)를 통해 MP3 플레이어(5)의 현재 작동상태가 표시(B)되고, 이와 동시에 MP3파일의 데이터를 판독(C)하여 그 데이터를 디코더(9)로 전송(D)하게 되며, 이에 따라 디코더(9)에서 복원된 디지털데이터가 DAC(7)로 전송(E)되어 전송된 디지털데이터가 DAC(7)에서 원래의 아날로드 신호로 재생(F)됨에 따라 음악을 들을 수 있게 된다.Accordingly, the key 10 constituting the mobile phone 6 as shown in FIG. 2 after connecting the MP4 player 5 to the mobile phone 6 by inserting the connector 4 into the connection terminal 2. (A) transfers the functions necessary to operate the MP3 player (5) to the MCU (11), the current operating state of the MP3 player (5) is displayed via the LCD (1), and at the same time MP3 The data of the file is read (C) and the data is transferred to the decoder 9 (D). Accordingly, the digital data restored by the decoder 9 is transferred (E) to the DAC 7 and transmitted. Is reproduced (F) by the original analog signal in the DAC 7 so that music can be heard.
한편, 본 고안에 따른 휴대폰은 MP3 플레이어(5)회로를 구성하는 MMC(8)를 이용하여 통화내용을 녹음할 수도 있는 바, 즉 도 3에 도시된 것과 같이 휴대폰(6)에 내장된 I.C(Codec I.C:12)를 이용하여 MMC(8)에 통화내용을 저장하고, 녹음된 내용을 MMC(8)에서 읽어 스피커 또는 이어 폰(13:Ear Phone)에서 재생하게 되는데, 이때 상기 I.C(12)에서는 녹음시에는 음성을 디지털 데이터로 바꾼 다음 압축하고, 재생시에는 디지털데이터를 압축해제한 다음 음성신호를 복원하도록 되어 있다.On the other hand, the mobile phone according to the present invention can record the contents of the call using the MMC (8) constituting the MP3 player (5) circuit, that is, the IC built in the mobile phone 6 as shown in FIG. By using the Codec IC: 12, the contents of the call are stored in the MMC 8, and the recorded contents are read from the MMC 8 and played on the speaker or the ear phone 13. The IC 12 In recording, audio is converted to digital data and then compressed, and during playback, the digital data is decompressed and then restored.
이상 설명한 것과 같이 본 고안 휴대폰에 착탈가능한 엠펙1 레이어3 플레이어에 의하면, 휴대폰에 접속할 수 있어 휴대폰으로 사용다가 필요시 휴대폰의 기본적인 기능을 이용하여 음악파일을 재생하여 청취할 수 있게 되므로써 사용성을 향상시킬 수 있고, 휴대폰과 중복되는 회로 및 기능을 휴대폰의 회로를 활용하여 구현하도록 하여 MP3 플레이어를 구성하는데에 소요되는 기본 제조비용을 절감할 수 있는 잇점이 있다.As described above, according to the MPEG1 Layer 3 player, which can be attached to or detached from the mobile phone, the mobile phone can be connected to the mobile phone, and when used as a mobile phone, the user can play and listen to music files using the basic functions of the mobile phone, thereby improving usability. In addition, it is possible to reduce the basic manufacturing cost of constructing an MP3 player by implementing a circuit and a function overlapping with a mobile phone by using the circuit of the mobile phone.
