    • An embedded loudspeaker system is set forth incorporating at least two asymmetric enclosures having different but overlapping frequency responses in order to achieve a substantially flat frequency response. At least one of the speaker enclosures is preferably ported (bass-reflex system) to provide as much output as possible in the low-frequency range. By using a plurality of speakers at least one of which has a bass reflex enclosure, a monophonic system is provided with a flat frequency response. The dimensions of the speaker enclosures are chosen such that the anti-resonance of one loudspeaker enclosure is compensated for by the resonance of another speaker enclosure, without making use of damping, so that no “notch” appears in the frequency response of the combined system at the listening position.
    • 提出了一种嵌入式扬声器系统,其包括具有不同但重叠的频率响应的至少两个不对称壳体,以实现基本平坦的频率响应。 扬声器外壳中的至少一个优选地被插入(低音反射系统)以在低频范围内提供尽可能多的输出。 通过使用其中至少一个具有低音反射外壳的多个扬声器,单音系统被提供有平坦的频率响应。 选择扬声器外壳的尺寸,使得一个扬声器外壳的反共振由另一个扬声器外壳的谐振补偿,而不利用阻尼,使得组合系统的频率响应中不会出现“陷波” 在聆听的位置。
