    摘要: An audio system including a left input channel signal, a right input channel signal, and a discrete center input channel. Circuitry removes correlated content from the left input channel signal and the right input channel signal and inserts the correlated content into the center input channel signal to provide a modified left input channel signal, a modified right input channel signal, and a modified center input channel signal. The modified left input channel signal is radiated by a directional loudspeaker so that radiation in a direction toward a listening area is less than radiation in other directions. The modified right channel input channel signal is radiated by a directional loudspeaker so that radiation in a direction toward a listening area is less than radiation in other directions.

    摘要: An three-way audio system that uses directional arrays for radiating mid-frequency acoustic energy and passive directional devices to radiate the high frequencies. the system includes a left channel, a right channel, and a center channel. A crossover network separates the left channel and the right channel into low frequency content, midrange frequency content, and high frequency content. An omnidirectional acoustical device radiates acoustic energy corresponding to the low frequency content of the combined left channel, right channel and center channel. A first directional array, comprising signal processing circuitry and more than one acoustic driver, radiates acoustic energy corresponding to the midrange content of one of the left channel and right channel signal so that more acoustic energy corresponding to the midrange content of one of the left channel signal and the right channel signal is radiated laterally than in other directions. A first passive directional device, radiates acoustic energy corresponding to the high frequency content of the one of the left channel and right channel signal so that more acoustic energy corresponding to the high frequency content of the one of the left channel signal and the right channel signal is radiated laterally than in other directions.

    摘要: The invention features a dual-mode audio system for an automobile which in one mode is configured for play while the doors to the automobile are closed, and in a second mode, is configured for play while a door, such as a tailgate, is opened. Additionally, the invention also features a battery monitor which monitors the operating condition of the battery and may estimate the energy capacity of the battery. The system may also take power conservation measures if the system determines that the engine is not running or the operating condition of the batter reaches a predetermined state. The invention also features a remote control integrated within a key fob for controlling the audio system. The invention features various orientations for mounting a pair of loudspeakers within an automobile which directly radiate sound out of a rear opening of the automobile.
