| 20080247587 | Condenser microphone, S/N ratio improvement therefor, and electronic device therefor - A condenser microphone includes a microphone chip and an LSI chip, which are stored in a microphone package having a sound hole. External sound enters the sound hole so as to propagate through the internal space of the microphone package, so that it is received by the microphone chip. The microphone package is designed to set the Helmholtz resonance frequency within the audio frequency range. The output signal of the microphone chip is supplied to an impedance converter included in the LSI chip. The output signal of the impedance converter is attenuated by an attenuation device with respect to the prescribed frequency band including the Helmholtz resonance frequency, which decreases when the condenser microphone is installed in the housing of an electronic device. Thus, it is possible to achieve the flat frequency characteristics in the output signal of the condenser microphone, which is thus improved in the S/N ratio. | 10-09-2008 |
