Abstract: A microphone which has a highly reliable microphone arm, can be reduced in weight and size, and is constituted by a pipe microphone for narration having good acoustic characteristics includes a voice receiving opening formed in the distal end portion of a hollow microphone arm extending from a microphone main body and having flexibility, a microphone unit arranged in the microphone main body, a ventilation hole formed in the microphone arm on the microphone main body side, wherein the ventilation hole is clogged with an unwoven fabric serving as a ventilation resistance member.

Abstract: An articulated telescopic microphone boom assembly is disclosed. The articulated telescopic microphone boom assembly includes a first hollow cylindrical telescoping boom attached to a hollow hinge assembly providing articulation with a second hollow cylindrical telescoping boom. The hollow hinge assembly includes a locking mechanism to fix the first hollow cylindrical telescoping boom at several predetermined angles in relation to the second hollow cylindrical telescoping boom. The first and second hollow cylindrical telescoping booms are each extended in a telescopic fashion and are fixed into place at a desired length. A microphone coupling means is secured to the one end of one of the cylindrical telescoping booms. An audio cable assembly is ensleeved within the articulated telescopic microphone boom assembly. The audio cable assembly male audio coupler is mounted in the handle and the audio cable assembly female audio coupler is mounted in the microphone coupling means.

Abstract: A microphone has an arm in a manner such that vibration generated by a loudspeaker or the like is transmitted to the microphone. The microphone characterized in that the arm supporting the microphone is constructed of a plurality of split arms, which are connected with each other through elastic members.

Abstract: An amplified sound system wherein a microphone is maintained at a desired acoustic zone in front of a speaker for enhancing performance in receiving sound emanated from said speaker. The system comprises a speaker cabinet containing at least one speaker, a microphone mount and a microphone for receiving sound emanated from said speaker. The microphone mount has an elongated support member for supporting said microphone at a desired spacial distance in front of the speaker. The support member has a first end attached to the speaker cabinet, and a second end on which the microphone is carried so that the microphone is positioned in a desired acoustic zone for collecting sound emanated from said speaker.

Abstract: An adjustable microphone stand is disclosed and includes a base having a protrusion extending from a surface thereof. A plurality of extension segments are configured to detachably connect to the base protrusion and an adjoining extension segment to adjust the height of the microphone stand. Each extension segment includes a protrusion extending from one end thereof, which is typically threaded, and a depression formed in an opposite end, which is interiorly threaded, so that each extension segment can be mated with either the base protrusion or an adjoining segment protrusion. Preferably, the extension segments are of varying lengths to facilitate adjustability of the microphone stand. The base also preferably includes a plurality of apertures through which fasteners can be inserted to fix the base to a surface, such as a wall.

Abstract: A support for a boom mounted microphone operated by a gaffer comprises a lightweight rigid harness and adjustable couplings, which extend outwardly from the front and rear of the harness to engage the boom. The couplings each include rigid portions extending outwardly from the harness at one end, in an upward direction and a toothed coupling mounted at the other end of the rigid portion. The toothed coupling is pivotable and rotatable. A tension adjustable air cylinder is mounted to each toothed coupling at one end and includes a swing swivel at the other end having a cylinder mounted thereto within which the boom is movably mounted.

Abstract: A portable electronic apparatus such as a personal digital assistant (IDA) with a telescopic transducer mount on which is mounted a microphone and an earphone, the positions of which are adjustable relative to one another to enable use of the apparatus in a number of different modes, with optimal positioning of the PDA display, microphone and earphone in relation to the user's eyes, ears and mouth.

Abstract: A collar band supports a boom-mounted microphone that may be selectively positioned on either the right or left side of the user's head. Adjustable neck pads are mounted to the opposite ends of the collar band for added comfort. The collar band may be resized to fit the neck of the user. The collar microphone may be worn for extended periods of time without becoming uncomfortable. A cradle assembly conveniently supports and stores the microphone when it is not in use.

Abstract: A microphone device includes a base adapted to be installed in a given position, an arm mounted on the base for angular movement in a predetermined angular range with respect thereto, and a sound pickup unit mounted on a distal end of the arm for picking up sounds when the arm is angularly positioned at a predetermined angle with respect to the arm. The base may be installed on a pillar positioned obliquely in front of the driver's seat of a motor vehicle, so that the microphone can be held in a good position with respect to the driver. The microphone is positioned in superposed relation or in the vicinity of the pillar that is present in the front vision of the driver on the driver's seat, and hence does not essentially interfere with the front vision of the driver.

Abstract: A vehicle seat backrest incorporates two speakers and an electrically driven extensible/retractable boom carrying a microphone. The boom is supported and guided in grooves in the casing of the extension/retraction assembly. It is constructed of two spring metal straps having arcuate cross section shapes and a flexible insulation layer between the straps. The straps serve as electrical conductors for the microphone and electrical signals are transmitted to and from the straps by brushes. The boom is activated by connection to a toothed belt carried on two toothed pulleys, one of which is driven by an electric motor. The headrest is used with a commercially available cellular telephone having a jack into which the microphone and speakers of the backrest are plugged.
