摘要： The present invention relates to an SMD type biased condenser microphone (200) having two terminals for a surface mounting process. The SMD type biased condenser microphone (200) includes a grounding terminal (218) for connecting with an external circuit, a set of diaphragm/backplate (206,210) one end of which is connected to the grounding terminal (218), for varying a capacity ( C 0) according to an intensity of sound pressure and converting sound into an electric signal, a DC-DC converter (232) for providing a bias voltage so as to form an electrostatic field at one side of the set of diaphragm/backplate (206/210), a buffer IC (240) for amplifying the electric signal from the set of diaphragm/backplate, and a decoupling capacitor (C1) for preventing the bias voltage output from the DC-DC converter from being directly applied to the buffer IC and transferring the electric signal from the set of diaphragm/backplate to the buffer IC. Therefore, the present invention can improve compatibility with a conventional ECM, and solve the directional problem of the circular condenser microphone in the surface mounting process, and also form the electrostatic field by applying a voltage from the outside so as to be capable of maintaining a constant electric field even after reflow work thereby preventing loss of sensitivity.

摘要： A condenser microphone (400) and a method of mounting a condenser microphone on a main PCB (200) are provided. The method includes the steps of: assembling the condenser microphone (400) by assembling elements of the condenser microphone such that a vibration plate including a couple of a diaphragm (412) and a backplate (408) is directed toward an opened surface of a casing (402) of the condenser microphone (400), the casing having a closed bottom surface and an opened surface opposite to the closed bottom surface, mounting a PCB (418) having a sound hole (418a) on the casing (402) and curling the opened surface of the casing such that a connecting terminal (420, 422) of the PCB is protruded compared to a curled surface; positioning the assembled condenser microphone (400) on a main PCB (200) such that the sound hole (418 a) of the PCB (418) of the condenser microphone is in accordance with a through hole (202) formed in the main PCB (200); and soldering the connecting terminal (420, 422) of the condenser microphone to a land of the main PCB. According to the present invention, if necessary, the main PCB can be mounted such that its elements surface is directed toward an inside of an electronic product, thereby maintaining good sound quality thanks to a short delivery path of sound wave.
