An audio system has a base station and a plurality of wireless microphones that are associated with the base station. The wireless microphones operate to capture acoustic audio information and to transmit this audio information to the base station. Each of the wireless microphones operate to detect whether or not they are connected to an external voltage source. If any of the plurality of the wireless microphones determines that they are not connected to an external voltage source, then it is controlled to transition to a first operational state. Or if a wireless microphone determines that it is connected to an external voltage source, and depending upon the voltage level detected, the microphone can transition to either a second or a third operational state.

Battery charging adaptor for a wireless microphone

An audio system is configured to support a number of wireless microphones, and each of the wireless microphones has one or more touch sensitive mute switches and a touch sensitive mute guard band switch. The mute guard band switch is connect to an electrically conductive surface that is proximate to a microphone peripheral surface that a user is likely to touch when they move the microphone. Logical instructions running in conjunction with a DSP associated with the microphone cause the audio system to override any mute commands it receives from any of the mute switches during the time that the guard band switch is activated.

Wireless microphone mute control override

An audio system has a base station, a speaker and one or more wireless microphones. The audio system operates to receive audio information from both a far-end audio source and a near-end audio source and to process the audio information for transmission to a far-end audio system. The wireless microphones have an electrically conductive element connected to a touch sensitive switch, and the electrically conductive element is proximate to an outer perimeter surface of the microphones. When the outer perimeter surface of the microphone is touched, the switch is activated which sends a microphone handling signal to the base station. The base station uses the microphone handling signal to control an operational characteristic of an audio signal processing function running on the base station.

Controlling acoustic echo cancellation while handling a wireless microphone

An audio conferencing system has a base station, a speaker and one or more mobile microphones, and it operates to receive audio information from both a far-end audio source and a near-end audio source and to process the audio information for transmission to a far-end audio conferencing system. At least one of the mobile microphones has a motion detection device and operates to send detected motion information to the base station. The base station operates to control the processing of audio information it receives from the microphone according to the detected microphone motion information.

Audio system signal processing control using microphone movement information

One or more audio conferencing systems are connected to a local network, and each conferencing system is comprised of a plurality of wireless microphones in communication with a plurality of antennas deployed in an array configuration. Each of the antennas comprising one of the audio conferencing systems is in direct communication with a base station and in indirect communication with a server which runs a centralized digital signal processing functionality. The digital signal processing functionality operates on audio information received from one or more far-end audio sources and from each of the one or more audio conferencing system.

Audio system with centralized audio signal processing

A digital audio conferencing system has a fixed base station that is in communication with a far end (R.E.) system over a communication network. The base station is associated with a wireless loudspeaker and one or more wireless microphones. The base station operates to receive F.E. audio signals to be played by the wireless loudspeaker, and it operates to remove acoustic echo picked up by the wireless microphones. A first clock controlling F.E. audio signal sampling at the base station, and a second clock controlling audio signal sampling and at a wireless microphone are synchronized to one master, reference clock that controls the operation of the base station. Acoustic echo included in an audio signal picked up by a wireless microphone is removed by AEC functionality running in the base station.
