    • A portable electronic device (100) that provides audio sound output from multiple internal speakers (114, 120) to a common output audio opening (108) in a housing of the portable electronic device is disclosed. In one embodiment, the multiple internal speakers (114, 120) are provided in close proximity to one another, such as adjacent to one another, and serve to produce audio sound pertaining to different audio channels. The sound (i.e., pressure waves) produced by each of the internal speakers (114, 120) is directed into a respective acoustic chamber (112, 118) and output via the output audio opening (108) in the housing (102). Accordingly, the acoustic chambers (112, 118) for the multiple internal speakers (114, 122) can each direct their audio sound output to the same output audio opening (108) in the housing (102). The respective acoustic chambers can be formed adjacent to one another with a structural barrier (122) serving to separate the distinct acoustic chambers (112, 118).
    • 公开了一种提供从多个内部扬声器(114,120)输出到便携式电子设备的壳体中的公共输出音频开口(108)的音频声音的便携式电子设备(100)。 在一个实施例中,多个内部扬声器(114,120)彼此靠近地设置,例如彼此相邻,并且用于产生与不同音频通道相关的音频声音。 由每个内部扬声器(114,120)产生的声音(即,压力波)被引导到相应的声学室(112,118)中,并通过壳体(102)中的输出音频开口(108)输出。 因此,用于多个内部扬声器(114,122)的声学室(112,118)可以各自将其音频声音输出引导到壳体(102)中的相同输出音频开口(108)。 相应的声学室可以彼此相邻地形成有用于分离不同声学室(112,118)的结构屏障(122)。
