    • A condenser microphone is provided to configure an electric circuit by using an FET as an impedance converter of the condenser microphone, thereby having a low band side attenuation function with simple circuit configuration. A microphone capsule(2) converts an electric sound by configuring a condenser by a facing electrode. An FET(3) impedance-converts a speech signal outputted from the microphone capsule. A CR circuit(6) is made of a resistor and a condenser and is connected to FET to adjust a signal level of a low frequency domain. An output terminal is drawn from a drain of an FET. The CR circuit is connected between a source and a ground of the FET. The CR circuit is connected between the source and the ground of the FET. A converting switch is installed between the source and the ground of the FET to control the CR circuit.
    • 提供电容式麦克风以通过使用FET作为电容式麦克风的阻抗转换器来配置电路,由此具有简单的电路配置的低频带侧衰减功能。 麦克风胶囊(2)通过由面对电极构成电容器来转换电声。 FET(3)对从麦克风胶囊输出的语音信号进行阻抗转换。 CR电路(6)由电阻器和电容器构成,并连接到FET以调节低频域的信号电平。 输出端子从FET的漏极引出。 CR电路连接在FET的源极和地之间。 CR电路连接在FET的源极和地之间。 转换开关安装在FET的源极和地之间,以控制CR电路。
