Abstract:
A microphone includes a housing unit, a capsule unit mounted on the housing unit, a noise-counteracting unit electrically connected to the capsule unit with opposite electrical polarity, and a damping unit connected to the housing unit. The capsule unit generates a primary electrical signal composed of a primary signal part attributed to an acoustic wave and a secondary signal part attributed to a first mechanical wave which is generated due to vibration of the housing. The noise-counteracting unit generates a secondary electrical signal attributed to the first mechanical wave and having an electrical polarity opposite to that of the primary electrical signal, so that the secondary electrical signal may counteract the secondary signal part of primary electrical signal. The damping unit generates a second mechanical wave to counteract the first mechanical wave when the first and second mechanical waves are transmitted to the capsule unit.
Abstract:
A musical instrument holder clip includes a first holding unit and a second holding unit. The first holding unit includes a main body and a clamping member that extends movably into the main body, and is operable to generate a clamping force adapted for clamping a microphone between the main body and the clamping member. The second holding unit includes a first holding member adapted for abutting against an outer surface of a bell wall of a wind instrument, and a second holding member adapted for abutting against an inner surface of the bell wall of the wind instrument. The first holding member and the second holding member cooperatively define a holding space adapted for receiving the bell wall of the wind instrument therebetween.
Abstract:
A microphone includes an outer casing, a carrier disposed in the outer casing, and a sound receiving module connected to the carrier. The carrier has a through hole opposite to the sound receiving module. An airtight unit includes a shock absorber and an airtight member cooperating with the outer casing and the carrier to define an airtight back chamber configured to generate a pneumatic wave when a mechanical vibration wave is transmitted to the outer casing. A damping material closes the through hole and is configured to change the phase of the pneumatic wave when the latter passes therethrough such that the pneumatic wave and the mechanical vibration wave can offset each other when they are transmitted to the sound receiving module.
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.
