    • A plurality of speakers (23) disposed in a front and a rear of a passenger and a controller (21) configured to control a sound field in a vehicle cabin by individually driving the plurality of speakers (23). The controller (21) is configured, when an operation input for changing an acceleration/deceleration behavior of the vehicle is made, to set a normative acceleration/deceleration GxT depending on the operation input, to detect an actual acceleration/deceleration GxR, and to displace the sound field in the vehicle cabin in the direction of a change in the actual acceleration/deceleration behavior of the vehicle depending on the deviation ΔG of the actual acceleration/deceleration GxR relative to the normative acceleration/deceleration GxT. That is, a change of an acceleration/deceleration behavior depending on the operation input is rendered before the change of the actual acceleration/deceleration behavior of the vehicle.
    • 配置在乘客的前部和后部的多个扬声器(23)和控制器(21),其被配置为通过单独地驱动多个扬声器(23)来控制车厢内的声场。 控制器21构成为,在进行用于变更车辆的加减速行为的操作输入时,根据操作输入来设定规范性的加减速度GxT,检测实际的加减速度GxR, 取决于实际加减速度GxR相对于标准加速度/减速度GxT的偏差ΔG,在车辆的实际加速度/减速度行为的变化方向上移动车厢内的声场。 即,在车辆的实际加速/减速行为发生变化之前,实现取决于操作输入的加速/减速行为的改变。

    • The invention is directed to a system for conducting sound system design, having a display and a processor. The processor is configured to cause the display to simultaneously show
      a visual representation of a sound system model and audio components and sound environment components;
      a first parameter associated with a sound system component; and
      a graphic representation of a first calculated sound system performance attribute dependent on the first parameter and a second calculated sound system performance attribute not dependent on the first parameter.
      The processor is further configured to receive a first input from a user which modifies the first sound system component and ,without additional user intervention, determines that the first calculated sound system performance attribute is affected by the user's modification to the first sound system component, and that the second calculated sound system performance attribute is not affected by the user's modification to the first sound system component. The processor calculates a new value of the first calculated sound system performance attribute, and causes the display to re-display the newly-calculated value of the first calculated sound system performance attribute. While causing the display to re-display the newly-calculated value of the first sound system performance attribute, the display continues displaying the graphic representation of the second calculated sound system performance attribute without re-calculating the second sound system performance attribute in response to the first user input.
    • 本发明涉及一种用于进行声音系统设计的系统,具有显示器和处理器。 处理器被配置为使得显示器同时显示声音系统模型和音频组件和声音环境组件的视觉表示; 与声音系统组件相关联的第一参数; 以及依赖于第一参数的第一计算声音系统性能属性和不依赖于第一参数的第二计算声音系统性能属性的图形表示。 处理器还被配置为从用户接收修改第一声音系统组件的第一输入,并且在没有额外的用户干预的情况下,确定第一计算的声音系统性能属性受到用户对第一音响系统组件的修改的影响,以及 第二个计算的声音系统性能属性不受用户对第一个声音系统组件的修改的影响。 处理器计算第一计算声音系统性能属性的新值,并使显示器重新显示第一计算的声音系统性能属性的新计算值。 当使显示器重新显示第一声音系统性能属性的新计算值时,显示继续显示第二计算声音系统性能属性的图形表示,而不响应于第二声音系统性能属性重新计算第二声音系统性能属性 第一个用户输入。
