具有偏移声音开口的手持电子设备
摘要：
一种改进的手持电子设备具有机壳，所述机壳具有形成于其中的伸长空腔。音频换能器与空腔流畅相通，并在机壳中形成多个声音开口，它们与空腔和手持电子设备周围的空气流畅相通。通常将声音开口与音频换能器的中心区相间隔，从而使声音开口按照比距离音频换能器更远的距离与机壳边缘相间隔。将空腔配置成形成赫尔姆霍茨共振腔，使得能够在音频换能器与声音开口之间通过空腔进行声音流通。声音开口与机壳边缘的间隔有助于用户在机壳与用户耳朵之间形成密封，从而使来自声音开口的声音进入耳朵并被用户感知。
摘要（英）：

An improved handheld electronic device has a case with an elongated cavity formed therein. An audio transducer is in fluid communication with the cavity, and a number of sound openings are formed in the case and are in fluid communication with the cavity and with the atmosphere surrounding the handheld electronic device. The sound openings are generally spaced from a central region of the audio transducer to space the sound openings generally farther from an edge of the case than the audio transducer. The cavity is configured to form a Helmholtz resonator that enables the communication of sound through the cavity between the audio transducer and the sound openings. The spacing of the sound openings from an edge of a case helps a user to form a seal between the case and the user's ear to enable sound from the sound openings to enter the ear and to be perceived by the user.
