Abstract

A microphone includes a capsule module including a carrier, a primary transducer unit and a secondary transducer unit. The carrier includes a hollow part mounted to a handle unit, and first and second carrier parts extending oppositely from the hollow part. The primary transducer unit is mounted to the first carrier part, and converts sound waves and vibration into a primary electrical signal a first secondary electrical signal, respectively. The secondary transducer unit is mounted to the second carrier part, and converts the vibration into a second secondary electrical signal for counteracting the first secondary electrical signal. The secondary transducer unit includes a diaphragm disposed within an airtight space.

Claims

9-1. The microphone as claimed in claim 9, wherein each of said first carrier part and said connecting segment of said second carrier part has an outer surface, and said primary transducer unit further includes a primary wiring board mounted to said outer surface of said first carrier part, and said secondary transducer unit further includes a secondary wiring board mounted to said outer surface of said connecting segment,

wherein said induction coil of said primary transducer is electrically connected to said primary wiring board, said secondary wiring board and said processing circuit in sequence, and said induction coil of said secondary transducer is electrically connected to said secondary wiring board and said processing circuit in sequence.
