Integrable Sensor System for Live Monitoring of Loudspeaker Performances

摘要

We here present a dedicated system capable of compensating loudspeaker distortion due to driver working condition or apparatus aging. The proposed monitoring system is formed by a reduced number of sensors that monitor the loudspeaker by a digital signal processing architecture (DSP) which performs a feedback to the loudspeaker amplifier so balancing its gain. All the sensors are designed to not interfere with output sound quality.
