    • A portable electronic device has an outer shell, a first speaker assembly, and a second speaker assembly. The first speaker assembly has a first speaker, a first speaker chamber, and an outer edge. The second speaker assembly has a second speaker, a second speaker chamber, and an outer edge. The first and second speaker assemblies are capable of being in a normal position, where the first speaker assembly outer edge and the second speaker assembly outer edge are substantially flush with the outer shell of said portable electronic device. The first and second speaker assemblies are also capable of being in an extended position, where the first speaker assembly outer edge and the second speaker assembly outer edge extend beyond the outer shell of the portable electronic device. Preferably, the first and second speaker chambers each have a larger volume when the first and second speaker assemblies are in the extended position than when they are in the normal position. This larger volume allows for higher quality sound--especially lower frequency sounds--to come from the portable electronic device when the first and second speaker assemblies are in the extended position. Preferably, the speaker assemblies are located in a hinged portion connecting a base portion of the portable electronic device with a display portion.
    • 便携式电子设备具有外壳,第一扬声器组件和第二扬声器组件。 第一扬声器组件具有第一扬声器,第一扬声器室和外边缘。 第二扬声器组件具有第二扬声器,第二扬声器室和外边缘。 第一和第二扬声器组件能够处于正常位置,其中第一扬声器组件外边缘和第二扬声器组件外边缘基本上与所述便携式电子设备的外壳齐平。 第一和第二扬声器组件也能够处于延伸位置,其中第一扬声器组件外边缘和第二扬声器组件外边缘延伸超过便携式电子设备的外壳。 优选地,当第一和第二扬声器组件处于延伸位置时,第一和第二扬声器室各自具有比当它们处于正常位置时更大的音量。 当第一和第二扬声器组件处于延伸位置时,这种更大的音量允许来自便携式电子设备的更高质量的声音(特别是较低频率的声音)。 优选地,扬声器组件位于将便携式电子设备的基部与显示部分连接的铰接部分中。
