    • The present invention relates to a loudspeaker circuit the performance of which can be adapted to the acoustics of the space in which it is placed. The loudspeaker circuit comprises a speaker (1), an input circuit (11) for applying a drive signal to the speaker, first means (6), e.g. a microphone, for monitoring the pressure at the speaker diaphragm (2), second means (3, 4), e.g. an accelerometer, for monitoring the velocity of the speaker diaphragm and third means (7), e.g. a filter, for defining a desired relationship between the monitored pressure and velocity. The difference between the desired relationship and actual relationship between the monitored pressure and velocity is reduced by a feedback circuit (9) driving the input circuit (11). The third means effectively multiplies the monitored velocity by a desired impedance value and a value representing the inter-relation between the output of the first means (6) and the drive signals applied to the loudspeaker.
    • 本发明涉及一种扬声器电路,其性能可以适应其放置空间的声学。 扬声器电路包括扬声器(1),用于向扬声器施加驱动信号的输入电路(11),第一装置(6) 用于监测扬声器振动膜(2)处的压力的麦克风,第二装置(3,4) 用于监测扬声器振动膜和第三装置(7)的速度的加速度计,例如。 一个过滤器,用于限定所监测的压力和速度之间的期望的关系。 通过驱动输入电路(11)的反馈电路(9)来减小所监视的压力和速度之间的期望关系和实际关系之间的差异。 第三装置有效地将所监视的速度乘以期望的阻抗值和表示第一装置(6)的输出和施加到扬声器的驱动信号之间的相互关系的值。
