708 results about "Wireless microphone" patented technology

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 his 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). Wireless microphones are widely used in the entertainment industry, television broadcasting, and public speaking to allow public speakers, interviewers, performers, and entertainers to move about freely while using a microphone without requiring a cable attached to the microphone.

Cordless RF range extension for wireless piconets

Cordless telephone technology provides a long range and highly sophisticated wireless extension between a plurality of wireless piconet networks. In one embodiment, base units of separate cordless telephones include respective piconet front ends (e.g., Bluetooth protocol bearing RF front ends) in addition to the otherwise conventional RF front end. The piconet-capable base units are placed and made members of separate piconet networks, but within conventional cordless telephone range of one another, e.g., within one mile of one another. To allow communications between piconet devices on the separate wireless piconet networks, the cordless telephone base units pass piconet content information (i.e., the messages passed by a piconet device on a first piconet network including a first cordless telephone base unit intended for receipt by another piconet device on a second piconet network serviced by the other cordless telephone base unit. In another embodiment, a base unit of a cordless telephone is made a member of a first wireless piconet network while its remote handset is made a member of a second wireless base unit, and piconet content information is passed from a device on one wireless piconet network to another device on the other wireless piconet network over the wireless cordless telephone (e.g., 900 MHz or 2.4 GHz range) channel established between the cordless telephone base unit and its remote handset.

Pairing modular wireless earpiece/microphone (HEADSET) to a serviced base portion and subsequent access thereto

The present invention provides a modular wireless headset to support voice communications when registered to a base unit. This modular wireless headset includes both a wireless microphone and wireless earpiece. The wireless earpiece may further include a wireless interface, a processing circuit, a speaker, a user interface, a pairing circuit, and a registration circuit. The wireless interface allows the wireless earpiece to wirelessly communicate with the base unit that couples the modular wireless headset to a servicing network. This coupling to the service network and base unit only occurs when the headset is successfully registered to the base unit. The pairing circuit and registration circuit allow the exchange of pairing or registration information between various wireless components. The pairing circuit allows the wireless earpiece and microphone to exchange pairing information which is then compared to determine whether or not a successful pairing can be achieved. Successfully paired wireless earpieces and wireless microphones wirelessly communicate. The registration circuit registers the modular wireless headset to the base unit when the registration information associated with the modular wireless headset and base unit compare favorably. Components of the modular wireless headset that do not pair successfully are uncoupled from the headset. Similarly, wireless headsets that fail to register are communicatively uncoupled from the base unit.

Wireless earphone and communication method for wireless earphone

The invention relates to a wireless earphone and a communication method for the wireless earphone. The wireless earphone comprises a master earphone and a slave earphone, and the master earphone establishes a Bluetooth link with another device to perform Bluetooth communication with the other device and to transmit relevant parameters of the Bluetooth link to the slave earphone, so that the slaveearphone monitors a Bluetooth signal from the other device. One earphone is configured to: in the case that a packet header of a Bluetooth audio data frame is correctly received but the Bluetooth audio data frame is not correctly received, send a first frame only comprising the information of the correctly received packet header of the Bluetooth audio data frame to the other earphone; and the other earphone is configured to: in the case that the Bluetooth audio data frame is correctly received and the first frame is received, send a second ECC frame to the one earphone. By adoption of the communication method for the wireless earphone, the reliability of Bluetooth transmission can be improved; the retransmission of audio data frame is reduced; and the synchronism of the Bluetooth audio data frame can be improved to optimize the stereo effect.
