또한, 상기 터치스크린(13)은 백라이트를 더 구비하여, 어두운 실내에서도 별도의 조명 없이 원하는 노래를 입력하고 선택할 수 있게 한다.In addition, the touch screen 13 further includes a backlight, so that a user can input and select a desired song even in a dark room without additional lighting.
또한, 본 고안은 전원, 리셋 및 주로 사용되는 기능을 설정하는 기능키(12)를 더 구비한다.In addition, the present invention further includes a function key 12 for setting a power supply, a reset, and a mainly used function.
이와 같이 구성된 본 고안의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
먼저, 사용자는 상기 터치스크린(13)의 검색조건 선택부(8)를 통하여 찾고자하는 노래의 곡명, 가수명, 가사 첫소절 및 신곡등의 검색조건을 설정한다.First, a user sets search conditions such as a song name, a singer's name, first lyrics, and a new song of a song to be searched through the search condition selection unit 8 of the touch screen 13.
이후, 문자입력창(7)에 스타일러스펜(10)을 이용하여 검색할 문자를 입력하고, 입력내용 표시부(6)에는 인식된 글자를 출력함과 동시에 검색결과 표시부(9)에는 일련번호, 곡명, 가수등의 검색 결과를 출력한다.Subsequently, a character to be searched is input to the text input window 7 using the stylus pen 10, and the recognized content is output to the input content display unit 6, and the serial number and song name are displayed on the search result display unit 9. Output search results such as and mantissa.
이와 같은 과정에서, CPU(14)는 상기 문자입력창(7)에 상기 스타일러스펜(10)으로 기록된 문자를 문자인식프로그램을 통하여 인식하고, 검색엔진을 통하여 상기 검색버튼(11)의 입력에 따라 입력된 문자에 대하여 음절 및 음소 단위로 상기 메모리(15)에 저장된 노래 데이터를 검색하고, 그 검색결과를 상기 검색결과 표시부(9)에 표시하는 것이다. 이때, 상기 메모리(15)는 곡명, 가수명, 가사 첫소절 및 신곡등의 키에 따른 노래 데이터가 미리 저장되어 있음은 물론이다.In this process, the CPU 14 recognizes the text recorded in the text input window 7 with the stylus pen 10 through a text recognition program, and inputs the search button 11 through a search engine. Accordingly, the song data stored in the memory 15 is searched for by the syllable and the phoneme unit, and the search result is displayed on the search result display unit 9. At this time, the memory 15 is stored in advance of the song data according to the key, such as the name of the song, the name of the singer, the first measure of the lyrics and the new song.
이후, 사용자는 원하는 곡이 상기 검색결과 표시부(9)에 표시되면, 표시된 곡명을 문자입력용 스타일러스펜(10)을 이용하여 선택하면, 이를 CPU(14)가 인식하고 적외선 송출기(1)를 통하여 검색된 노래를 재생시키기 위한 원격제어신호를 가요반주기로 송출한다. 이때, 실행버튼(5)을 선택하면 송출되는 실행명령의 종류를 선곡, 예약, 취소 등으로 선택 입력할 수 있다.Thereafter, when a desired song is displayed on the search result display unit 9, the user selects the displayed song name using the stylus pen 10 for text input, and the CPU 14 recognizes the selected song name through the infrared emitter 1. The remote control signal for playing the found song is sent out in a flexible music cycle. At this time, if the execution button 5 is selected, the type of the execution command to be sent can be input by selection, reservation, or cancellation.
한편, 입력할 단어를 모두 입력하여도 원하는 곡을 아직 찾지 못했을 경우에는 검색버튼(11)을 눌러 입력된 단어를 포함하는 모든 문자에 대하여 검색을 수행시키게 한다.On the other hand, even if all the words to be entered, even if the desired song has not yet found by pressing the search button 11 to perform a search for all characters including the entered word.
아울러, 상기 터치스크린(13)에는 백라이트가 구비되어 있어, 어두운 실내에서도 별도의 조명 없이 원하는 노래를 입력하고 선택할 수 있다. 또한, 본 고안은 전원, 리셋 및 주로 사용되는 기능을 설정하는 기능키(12)를 더 구비하여, 노래 선곡을 더욱 편리하게 할 수 있다.In addition, the touch screen 13 is provided with a backlight, so that a user can input and select a desired song even in a dark room without additional lighting. In addition, the present invention further includes a function key 12 for setting a power supply, a reset, and a mainly used function, so that song selection can be made more convenient.
본 고안은 상기에 설명된 실시예에 한정되지 아니하며, 청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 본 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이고, 그와 같은 변경은 기재된 청구범위 내에 있게 된다.The present invention is not limited to the above-described embodiments, and any person having ordinary skill in the art to which the present invention pertains may make various modifications without departing from the gist of the present invention claimed in the claims. Such changes are intended to fall within the scope of the claims set forth herein.
이상에서 설명한 바와 같이 본 고안에 따른 문자인식 PDA를 활용한 가요반주기용 전자식 선곡 장치에 의하면, 가요반주기를 사용할 경우, 종래 어두운 조명으로 인한 선곡의 어려움이나 두꺼운 책자(선곡집)를 앞뒤로 일일이 찾아야 하는 어려움 및 시간적 낭비를 줄이고, 선곡과 동시에 기존의 원격 리모콘 기능을 모두 사용할 수 있는 효과가 있으며, 문자인식 PDA를 활용하여 음절 및 음소 단위의 문자를 사용자가 스타일러스펜으로 직접 입력하여 선곡함으로써, 신속하고 편리하게 원하는 곡을 선택할 수 있는 다양한 효과가 있다.As described above, according to the electronic music selection device for the flexible half period using the character recognition PDA according to the present invention, when using the flexible half period, the difficulty of selecting songs due to the conventional dark lighting or the thick booklet (selective collection) one after another And it reduces the waste of time, and can select all of the existing remote control functions at the same time as the selection, and by using the text recognition PDA, users can directly enter the syllables and phoneme characters by stylus pen to select them quickly and conveniently. There are a variety of effects to choose from.
