改变扬声器信号的系统和方法

System and method for adapting a loudspeaker signal

Abstract

A system and a method for adapting a loudspeaker signal. A sound system 100 for producing sound on a loudspeaker 130 is provided wherein the temperature of a voice coil of the loudspeaker may be monitored continuously. The sound system comprises a signal generator 150 for generating an evaluation signal which is combined with an input sound signal 120 to obtain a loudspeaker signal and a monitor 140 for monitoring an electric response of the voice coil to the loudspeaker signal. The loudspeaker signal may be adapted 180 to control the temperature of the voice coil in dependency upon the monitored response. The system can determine the temperature of the voice coil 170 even if the input sound signal comprises only little sound energy.
改变扬声器信号的系统和方法。提出了一种用于在扬声器(130)上产生声音的音响系统(100),其中可以连续地监测扬声器的语音线圈的温度。音响系统包括:信号发生器(150),用于产生估计信号,估计信号叠加到输入声音信号(120)上以获得扬声器信号;以及监测器(140),用于监测语音线圈对于扬声器信号的电响应。扬声器信号可以适用于(180)依赖于所监测的响应来控制语音线圈的温度。甚至在输入声音信号包含很小声音能量的情况下,系统也可以确定语音线圈(170)的温度。
