Actuator is a harmonic generator, use one of the psycho-acoustic characteristics of sound signals are modified and beautification of sound-processing equipment. By giving voice to increase high-frequency harmonics components and so on many kinds of methods that can improve the sound, tone, increased penetration of the voice, increased sound sense of space. Not only can the modern actuator to create high-frequency harmonics, but also have low frequency extension and musical styles, and other features that make the bass more perfect, more expressive music.

Use the actuator enhance audio clarity, can be about sex and expressiveness. Make the sound more enchanting, lower listening fatigue, increased loudness. Although the exciter only increased to sound around the harmonic constituents 0.5dB, but the actual sounds, volume increased by about 10dB seems. The sound of auditory loudness increase markedly, three-dimensional sense of sound images, and sound isolation degree increase; improved sound positioning and layering, you can improve the sound quality of the sound playback, tape replication rate. Because the sound signal transmission and recording process will be a loss of high frequency harmonics components, high-frequency noise. At this point, the former with the actuator to signal to compensate, the latter available filter will filter out high frequency noise, and then create a treble components, ensure playback sound quality.

Actuator in need audio ' system of sound and timbre to discrimination, according to subjective listening evaluation.
