Abstract

The invention provides a plane diagram combined server type servo system and a control method thereof. A driving coil of a loudspeaker in the system matches a precise diagram position feedback sensor group correspondingly, each diagram position feedback sensor group comprises a medium-high frequency sensing module and a low frequency sensing module at least, the medium-high frequency sensing module and the low frequency sensing module measure medium-high frequency amplitude and low frequency amplitude in vibration of a diaphragm part controlled by the corresponding driving coil respectively, and transmit corresponding measuring signals to a control unit, and the control unit realizes high-speed precise servo control via a digital algorithm. Nonlinear distortion is controlled within the minimal range to the largest extent theoretically, an integral plane diaphragm of brand new design is used to replace a present tapered diaphragm, and waveform can be restored completely. The system is a transduction system in which electronics are combined with machinery deeply and diaphragm motion amplitude is basically consistent with input signals.

Description

technical field [0001] The invention relates to the field of loudspeakers, in particular to a system structure and control method of a composite servo high-fidelity loudspeaker system with a planar diaphragm and position feedback. Background technique [0002] Audio recording and playback has a history of more than 100 years, but it has not been fundamentally improved. The essence of audio recording and playback is a process of restoring the recorded signal at a certain point through the playback system. Theoretically speaking, the essence of audio recording and playback system is to restore sound. The transducers at both ends of the recording and playback system are extremely important. The microphone is a transducer from a physical signal to an electrical signal, which is responsible for converting physical vibration into an electrical signal, while the speaker is a transducer from an electrical signal to a physical signal. Electrical signals are converted into physical ...
