1.Electric cylinder loudspeaker
Electric cylinder loudspeaker is also known as tweeter, and its structure is shown in Figure 1.It is mainly composed of three parts: magnetic circuit system, vibration system and acoustic drum.The magnetic circuit system and vibration system are assembled together, called the articulation head.The articulation head and the harmonic can be separated into one body.
2.Electric paper pot speaker
Electric paper basin loudspeaker is also called woofer.It is mainly composed of magnetic circuit system and vibration system.
The magnetic circuit system consists of a circular permanent magnet and soft iron, with the magnetic field concentrated in the gap.The vibration system consists of a paper basin with a voice coil, which is held in the middle of the gap by an elastic sheet.When an audio current passes through, the voice coil moves back and forth with the paper basin under the action of magnetic force, thus producing sound.
3.Modular loudspeaker
In order to improve the sound playback quality, expand the effective frequency range, usually will be several different frequency response range of loudspeaker combination together, into the same sound box, constitute a combination of sound box.It can significantly improve the frequency response curve over the entire audio range.
