Sound refers to other sounds other than human language and music, including the sound of the natural environment, the sound of the animal, the sound of the machine tool, the various sounds made by the human movement.
The sound may include power amplifier, peripheral equipment (including pressure limiter, effect device, equalizer, VCD, DVD, etc.), loudspeaker (sound box, horn), mixer, microphone, display device and so on. Among them, speakers are voice output devices, speakers, subwoofer and so on. A loudspeaker includes high, low and medium speakers, but not necessarily 3. The development history of technology can be divided into electron tube, transistor, integrated circuit and field-effect transistor.

The principle of sound transmission of ordinary (horn) sound
Medium resonance mixed sound, sound principle, the use of vibrator vibration sound + paper drum horn sound, we often use sound people know, ordinary sound in addition to professional sound, ordinary sound heavy bass are not enough, low sound a good point of the general volume is not small, this is mainly due to the use of loudspeaker sound The sound is greatly influenced by the size of the sound unit body, so a lot of multi-media audio directly uses the bass gun and the external sound box, which fully expands the volume of the sound unit body, but it has a great limitation on the sound and sound shape. This is why the sound we see in the city is usually the four square square. The reason for this is that the bass effect is not very good.
