<p>The present invention relates to a condenser microphone which provides a normal operation and an improvement of yield. In order to achieve the above object of the invention, there is provided a electret microphone comprising: a casing; an internally housed components housed by the casing, the components including a vibrating plate, a spacer, a back plate, a first base ring and a second base ring; a printed circuit board for receiving an electrical signal from at least one of the vibrating plate and the back plate; a washer spring for providing an elasticity between the components, and among the components, the casing and the printed circuit board. In accordance with the condenser microphone including the washer spring, the microphone operates normally even an error occurs during a manufacturing process, a uniform product quality is maintained, and reduces a defect rate to remarkably improve a manufacturing yield. In addition, in accordance with the condenser microphone including the washer spring, the washer spring may be easily applied, and an effective and reasonable selection of the microphone and an application of the manufacturing method thereof are possible by showing an effective characteristic and a resulting effect and function.</p> |
