Raymond A. Litke (1920-1986) was an American electronic engineer, the inventor of a practical wireless microphone, and the first to patent the wireless microphone. He was born and raised on a farm near Alma, Kansas, but spent most of his adult life in San Jose, California.
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.
Website. www.bluetooth.com. A Bluetooth earbud, an earphone and microphone that communicates with a cellphone using the Bluetooth protocol. Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs).
The wireless data exchange standard Bluetooth uses a variety of protocols. Core protocols are defined by the trade organization Bluetooth SIG. Additional protocols have been adopted from other standards bodies. This article gives an overview of the core protocols and those adopted protocols that are widely used. The Bluetooth is split in two parts: a "controller stack" containing the timing ...
In order to use Bluetooth, a device must be compatible with the subset of Bluetooth profiles (often called services or functions) necessary to use the desired services. A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices.
A rule change to make this permanent is proposed. There are currently some wireless microphone manufacturers that are marketing wireless microphones for use in the United States that operate within the 944 to 952 MHz band reserved for studio-transmitter link communications.
A microphone, colloquially called a mic (/ maɪk /), [1] or mike, [a] 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 ...
Java APIs for Bluetooth Wireless Technology (JABWT) is a J2ME specification for APIs that allows Java MIDlets running on embedded devices such as mobile phones to use Bluetooth for short-range wireless communication. JABWT was developed as JSR-82 under the Java Community Process.
