    • The present invention relates to an electret condenser microphone and a main board including the same wherein the electret condenser microphone is mounted on a back side of the main board on which relatively large circuit components or parts are mounted so that the electret condenser microphone is easily mounted without preparing a separate space and a manufacturing process thereof is simplified. The electret condenser microphone in accordance with the present invention comprises: a casing; an acoustic processor for converting an external acoustic signal to an electrical signal, the acoustic processor being enclosed by the casing; and a printed circuit board including an acoustic hole, wherein the printed circuit board removes a noise included in the electrical signal and amplifies the electrical signal to generates an acoustic signal, the printed circuit board comprising a pad for delivering the acoustic signal to an outside. The electret condenser microphone and the main board including the same does not employ an interface board for bonding the electret condenser microphone to the main board so that a space required for mounting the electret condenser microphone is minimized and a manufacturing process is simplified, thereby reducing a cost for manufacturing and mounting of the electret condenser microphone.
    • 本发明涉及一种驻极体电容麦克风及包含该驻极体电容麦克风的主板,其中驻极体电容麦克风安装在主板的背面,在该背板上安装了较大的电路部件或部件,以便驻极体电容麦克风易于安装 而不需要制备单独的空间,并且其制造方法被简化。 根据本发明的驻极体电容传声器包括:壳体; 用于将外部声学信号转换为电信号的声学处理器,所述声学处理器被所述壳体包围; 以及包括声孔的印刷电路板,其中所述印刷电路板去除包括在所述电信号中的噪声并放大所述电信号以产生声信号,所述印刷电路板包括用于将声信号传送到外部的焊盘。 驻极体电容麦克风及包含该驻极体电容麦克风的主板不使用用于将驻极体电容式麦克风接合到主板的接口板,使得驻极体电容麦克风的安装所需的空间最小化,并且制造过程简化 制造和安装驻极体电容话筒的成本。
