Wireless Microphones
A wireless microphone, or cordless microphone, is a microphone without a physical cable connecting it directly to the sound recording or amplifying equipment with which it is associated. Also known as a radio microphone, it has a small, battery-powered radio transmitter in the microphone body, which transmits the audio signal from the microphone by radio waves to a nearby receiver unit, which recovers the audio. The other audio equipment is connected to the receiver unit by cable. In one type the transmitter is contained within the handheld microphone body. In another type the transmitter is contained within a separate unit called a "bodypack", usually clipped to the user's belt or concealed under their clothes. The bodypack is connected by wire to a "lavalier microphone" or "lav" (a small microphone clipped to the user's lapel), a headset or earset microphone, or another wired microphone. Most bodypack designs also support a wired instrument connection (e.g., to a guitar). Wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Headphone
Headphones are a pair of small loudspeaker drivers worn on or around the head over a user's ears. They are electroacoustic transducers, which convert an electrical signal to a corresponding sound. Headphones let a single user listen to an audio source privately, in contrast to a loudspeaker, which emits sound into the open air for anyone nearby to hear. Headphones are also known as earspeakers, earphones or, colloquially, cans. Circumaural ('around the ear') and supra-aural ('over the ear') headphones use a band over the top of the head to hold the speakers in place. Another type, known as earbuds or earpieces consist of individual units that plug into the user's ear canal. A third type are bone conduction headphones, which typically wrap around the back of the head and rest in front of the ear canal, leaving the ear canal open. In the context of telecommunication, a headset is a combination of headphone and microphone. Headphones connect to a signal source such as an audio ...

Microphone
A microphone, colloquially called a mic or mike (), is a transducer that converts sound into an electrical signal. Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, and radio and television broadcasting. They are also used in computers for recording voice, speech recognition, VoIP, and for other purposes such as ultrasonic sensors or knock sensors. Several types of microphone are used today, which employ different methods to convert the air pressure variations of a sound wave to an electrical signal. The most common are the dynamic microphone, which uses a coil of wire suspended in a magnetic field; the condenser microphone, which uses the vibrating diaphragm as a capacitor plate; and the contact microphone, which uses a crystal of piezoelectric material. Microphones typically n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kommanditgesellschaft
A (abbreviated "KG", ; from + ) is the German name for a limited partnership business entity and is used in German, Belgian, Dutch, Austrian, and some other European legal systems. In Japan, it is called a ''gōshi gaisha''. Its name derives from the commenda, an early Italian medieval form of limited partnership. Description Partnerships may be formed in the legal forms of General Partnership (, GbR), or specialized in trading (, OHG), or Limited Partnership (''Kommanditgesellschaft'', KG). In the OHG, all partners are fully liable for the partnership's debts, whereas in the KG there are general partners (''Komplementär'') with unlimited liability and limited partners (''Kommanditisten'') whose liability is restricted to their fixed contributions to the partnership. Although a partnership itself is not a legal entity, it may acquire rights and incur liabilities, acquire title to real estate and sue or be sued. For example, a ''Gesellschaft mit beschränkter Haftung A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Noise-canceling Microphone
A noise-canceling microphone is a microphone that is designed to filter ambient noise. Technical details The development is a special case of the differential microphone topology most commonly used to achieve directionality. All such microphones have at least two ports through which sound enters; a front port normally oriented toward the desired sound and another port that's more distant. The microphone's diaphragm is placed between the two ports; sound arriving from an ambient sound field reaches both ports more or less equally. Sound that's much closer to the front port than to the rear will make more of a pressure gradient between the front and back of the diaphragm, causing it to move more. The microphone's proximity effect is adjusted so that flat frequency response is achieved for sound sources very close to the front of the mic – typically 1 to 3 cm. Sounds arriving from other angles are subject to steep midrange and bass rolloff. Commercially and militarily usefu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
