Signal processing method and signal processing system

Abstract

The invention provides a signal processing method and a signal processing system which are applied in the environment of signal separation application which takes a diaphragm of an earphone monomer asan inductor and used for analyzing out the earphone wearing state of a user. When the signal processing method is conducted by means of the signal processing system, an induction signal which is generated by the diaphragm of the earphone monomer and related to the using state of the earphone monomer is acquired by a differential amplifier and pushed back to a sensing analog-digital converter fordigital processing to remove residual music signals to be beneficial to follow-up processing, and therefore a scratch pad storage is additionally arranged to be used for conducting processing of residual music signal removal in a functional area after adjusting and setting the first-in first-out depth and the clock speed of a scratch area of the scratch pad storage to be synchronous with the totaldelay of external transmission to separate out an induction signal of displacement of the diaphragm of the earphone monomer and take the acquired induction signal as a reference source for follow-upanalysis and automatic control and / or signal compensation.

Description

technical field [0001] The present invention relates to a signal processing system and method. More specifically, it relates to a signal processing system and method applied to the environment of signal separation application with the single diaphragm of the earphone as the sensor, to analyze the user According to the wear status of the earphones, the induction signals related to the use status of the earphone monomers generated by the displacement of the earphone monomer diaphragms are obtained, and the acquired induction signals are used for subsequent analysis and automatic control and / or signal compensation. source of reference. Background technique [0002] In the current headphone technology, the pressure resistance of the driver unit (Driver Unit) that outputs sound waves of various headphones to the front and rear cavity (Cavity) of the diaphragm (Diaphragm) changes, for example, wearing (donned), taking off (doffed), vibration (For example, tapping the earphone she...

[0002] In the current headphone technology, the pressure resistance of the driver unit (Driver Unit) that outputs sound waves of various headphones to the front and rear cavity (Cavity) of the diaphragm (Diaphragm) changes, for example, wearing (donned), taking off (doffed), vibration (For example, tapping the earphone shell with your fingertips), there will be electrical output, that is, due to the force displacement of the diaphragm, there will be a change in the magnetic field, and a current signal will be generated. However, at present, the generated current is only The signal is treated as a signal other than the audio playback signal, and is not utilized and applied
