More Information
Summary:An electronic device includes an internal microphone that is located remotely from a microphone aperture formed in the enclosure of the electronic device. An acoustic chamber is formed within the electronic device to couple the microphone to the microphone aperture. The acoustic chamber is designed with a particular length to volume ratio that amplifies a particular range of frequencies such thatthe microphone maintains equal sensitivity to a desired frequency band. 本发明题为"用于远程定位的音频设备的声学补偿室"。本发明公开了种电子设备，该电子设备包括内部麦克风，该内部麦克风距形成在电子设备的壳体中的麦克风孔远程定位。在电子设备内形成声室以将麦克风耦接到麦克风孔。该声室被设计成具有特定的长度与体积比，该特定的长度与体积比放大特定频率范围，使得麦克风维持对期望频带的相等灵敏度。
