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 ...
Litke’s wireless mike resembled a silver tube with “a microphone at the top, a transmitter in the middle and its battery power supply at the bottom.” [1] It was 6 inches long, 1 inch in diameter, and weighed 7 ounces; the device had a broadcast range of up to a half-mile. Two types of mikes were available: lavalier and hand-held.
In the UK, the use of wireless microphone systems requires a Wireless Telegraphy Act license, except for the license-free bands of 173.8–175.0 MHz and 863–865 MHz. These license-free bands are sometimes referred to as "Channel 70" (not to be confused with TV Channel 69, which operated on 854–862 MHz and always required a license from JFMG ...
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).
With this technique is the angle between the microphone axes α = ± 55° = 110° and the distance between the cardioid microphones (microphone basis) is in this case a = 17 cm and gives a total recording angle of 96°. The choice between one and the other depends on the recording angle of the microphone system and not on the distance to and ...
For example, music can be streamed from a mobile phone, laptop, or desktop to a wireless headset, hearing aid/cochlear implant streamer, or car audio; voice can be streamed from a microphone device to a recorder on a mobile phone or computer. [1]
Experiments show that the system can identify the direction of the source well in a certain range of angle of arrival. It cannot identify the sound coming outside the range due to the collapsed spectrum pattern of the reflector. Binaural hearing use only 2 microphones and is capable of concentrating on one source among multiple sources of noises.
A long-range laser rangefinder is capable of measuring distance up to 20 km; mounted on a tripod with an angular mount. The resulting system also provides azimuth and elevation measurements. A laser rangefinder, also known as a laser telemeter, is a rangefinder that uses a laser beam to determine the distance to an object.
