在录音技术和回放工作上，人们很快会发现他们可以创作出全新的声音。通过将电信号传送给一个扬声器，该声音在生活中从未存在过，扬声器可作为乐器本身的一部分。
一个生成的声音
生成声音源于技术设备的帮助，例如计算机。
你刚才听到的是一个生成的声音，生成的声音被用于电子音乐。
生活中的许多情况下都会遇到生成的声音，你听到的音乐也可能是由这些声音构成的。
发现声音成分
随着电子技术的发展，它可帮助检查声音是如何工作的。
科学家研究了声音的基础属性以及通过创建电路来帮助再生成和创作新的声音。
他们使用示波器（一件可以在视屏上显示声波的设备）查看声波：
建设新的声音
几乎所有的电子乐器都是一种被称作振荡器的电子部件。他们创建了一个信号波，可以来回移动(波可被描述为振荡）。几乎所有的电子设备所产生的声音都包含一个振荡器。
这些振荡的电信号传入扬声器并转换为声波：
通过控制电子振荡器可以创作不同音高、响度和时值的声音。
而不同种类的振荡器创作出的声音音色也将不同。
通过合并单一的基础声波可能创作出一个无限数量的新声音质地。
新乐器
许多早期的电子乐器是由声学乐器扩展而来的（例如电吉他）但其他崭新的乐器很快被发明出来了。

Working with the technology of sound recording and playback, people soon discovered that they could create entirely new sounds. By manipulating the electrical signal sent to a loudspeaker, sounds that had never existed before came to life. The loudspeaker became part of an instrument itself.
A generated sound
Generated sounds are made with the help of technical equipment, for example a computer.
What you just heard is a generated sound. Generated sounds are used in Electronic music.
You might have come across generated sounds in many situations in your life. And it is very likely that you will have heard music using these sounds.
Uncovering the Ingredients of Sound
With the help of electronic technology it was possible to examine how sounds worked.
Scientists investigated the basic properties of sound and then created electrical circuits which could reproduce and create new sounds.
They used oscilloscopes (a piece of equipment that displays sound waves on a visual screen) to view the soundwaves:
Building New Sounds
Inside nearly all electronic instruments is an electrical part called an oscillator. These create a Signal Wave which moves back and forth (the wave can be described as oscillating). Almost any electrical device that produces its own sound will contain an oscillator.
These oscillating electrical signals are then fed to a loudspeaker and are converted into sound waves:
By controlling the electronic oscillator it is possible to create sounds of different Pitch, Loudness, and Duration.
While different types of oscillators will create sounds that have a different Timbre.
By combining individual basic sound waves it is possible to create an unlimited number of new sonic textures.
New Instruments
Many early electronic instruments were extensions to existing acoustic instruments (e.g. the Electric guitar) but other brand new instruments were soon invented.
