一套完整的音響,一定包括播放設(shè)備、放大設(shè)備、換能器,缺一不可,結(jié)合音源,就可以重播出聲音了。
A complete set of sound, must include playback equipment, amplification equipment, transducer, indispensable, combined with sound source, you can re broadcast the sound.
放大器(也稱功放器,擴音機),可以再拆分成前級放大器、后級放大器(也稱功率放大器),是放大模擬音頻信號中的高電平信號,也即線路電平(LINELEVEL);古董級、但近年又回?zé)岬暮谀z,其唱頭拾取的是電平極低的信號,需要經(jīng)過“唱頭放大器”;驅(qū)動耳機的電流會比前級稍大一些,所以會有獨立的耳機放大器,但居多結(jié)合在前級或播放設(shè)備內(nèi)。
Amplifier (also known as power amplifier, amplifier), can be divided into pre amplifier, post amplifier (also known as power amplifier), is to amplify analog audio signal in the high level signal, that is, line level (line level); Antique grade, but in recent years, the heat of the black glue, the pickup is very low level signal, need to go through the "cartridge amplifier"; The current of driving headphones will be slightly larger than that of the previous stage, so there will be independent headphone amplifiers, but most of them are combined in the previous stage or playback equipment.
換能器就是耳機、音箱了。播放設(shè)備就復(fù)雜了(前置,多稱前端,就是指播放器)?,F(xiàn)在能接觸到的模擬播放設(shè)備,只是收音頭(不是收音機,沒喇叭的,只輸出音頻信號)和黑膠唱機了。數(shù)字播放設(shè)備,有“傳統(tǒng)”的CD機,有硬盤數(shù)碼音頻播放器,有串流播放器(也稱流媒體播放器、數(shù)碼流播放器),對了,電腦、手機也可以是播放器。
Transducers are earphones and speakers. The playback device is complicated (front-end, or front-end, or player). The only analog playback devices that can be accessed now are the radio head (not the radio, no speaker, only output audio signal) and the vinyl phonograph. Digital player devices include "traditional" CD player, hard disk digital audio player and Streaming Player (also known as streaming media player and digital streaming player). By the way, computers and mobile phones can also be players.
這些數(shù)字類的播放器,可以拆分成轉(zhuǎn)盤、解碼器,甚再拆分出數(shù)字界面(DDC)和時鐘,而串流播放器還需要連接路由器。這播放、放大、換能器三部分,合在一塊就是一體式音響,比如收音機就是,能插SD卡的藍牙音箱也是,其實手機也是。
These digital players can be split into turntable, decoder, and even digital interface (DDC) and clock, and the serial player also needs to be connected to router. The three parts of playback, amplification and transducer are integrated into an integrated audio system. For example, the radio is an integrated audio system, and so is the Bluetooth speaker that can plug in the SD card. In fact, the mobile phone is also an integrated audio system.
很多數(shù)碼播放器都帶耳放,接上耳機就是一套音響;老式的床頭音響,播放器、放大器做成一體,接兩只音箱就成一套?,F(xiàn)在一些歐美企業(yè),喜歡把數(shù)播、串流播放器和放大器做成一體,個人很欣賞這種器材。
Many digital players are equipped with earphones, which is a set of sound; Old style bedside sound, player, amplifier into one, then two speakers into a set. Now some European and American brands like to integrate digital broadcasting, serial player and amplifier. I really appreciate this kind of equipment.
還有把后級放大器和音箱結(jié)合在一起的,錄音室使用的有源監(jiān)聽音箱就是,把它民用化個人是非常看好的。當(dāng)然,廉價的電腦箱也算是后級+音箱+電位器。連接的話,播放器接放大器是使用音頻信號線,蓮花頭的(RCA頭),前后級之間也是,放大器接音箱是音箱線,就這么簡單。進階的接法,包括數(shù)字設(shè)備,就要另起爐灶來講了。
There is also a combination of the post amplifier and speaker. The active monitor speaker used in the recording studio is just like this. It's very promising to popularize it. Of course, the cheap computer box can also be regarded as the back stage + speaker + potentiometer. If you connect the player to the amplifier, you use the audio signal cable, the RCA head, and between the front and rear stages. The amplifier to the speaker is the speaker cable, which is so simple. Advanced connections, including digital devices, are about to start a new business.
