Embodiment Construction

[0064] The following description focuses on the application of the invention to loudspeaker systems. However, the invention is not limited to such applications and can be applied to other sound transmission and reproduction devices, such as those stated at the end of the description.

[0065] Referring now to the drawings, wherein like numerals indicate like or corresponding parts throughout the figures, and in particular figure 1 , shows a system 10 incorporating the present invention. System 10 includes a signal source 12 for providing electroacoustic signals. The signal source can be, for example, a CD player. Output 14 from signal source 12 is input to a compensation system 16 that employs detailed features and aspects of the present invention. The output 14 is processed by a compensation system 16 to produce a compensated electro-acoustic signal 18 which is fed to a power amplifier 19 and a loudspeaker 20 .

[0066] refer to figure 2 The compensation system 16 emplo...

Abstract

A sound compensation system alters an electrical audio signal for input to a sonic reproduction device having associated behavioral characteristics. The behavioral characteristics of the device are defined by individual or groups of individual components of the sonic reproduction device and include mechanical, acoustic and electromagnetic behaviors. The model includes a plurality of filters that simulate at least one of the behavioral characteristics of the sonic reproduction device. The filters are defined by digital signal processes or by analog circuits and are characterized by one or more of an associated frequency, time, phase and transient response. These responses combine to define an overall response for the model. The filters include adjustable parameters which are used to alter filter responses to produce responses that are conjugates to the responses of the unaltered filters and thus the sonic reproduction device. A controller modifies the parameters.

Description

[0001] This application is that the international application date is August 10, 2000, the international application number is PCT / US00 / 21916, the Chinese national application date is August 10, 2000, the application number is 008115567, and the invention title is "Used for sound reproduction. Compensation system and method" patent application divisional application. technical field [0002] The present invention relates generally to a compensation method and system for use in sound transmission and reproduction systems, and more particularly to a compensation method and system for using parameter values ​​to control or regulate a process having a transformation or model that Or models have properties or responses like components or elements used in transmission or reproduction systems. Background technique [0003] Most audio reproduction systems use electromechanical speakers to acoustically reproduce audio signals. The electrical, mechanical, and acoustic properties of l...
