摘要： A loudspeaker system can have first and second loudspeakers selectively operable in a single-channel mode or in a multi-channel mode. In the single-channel mode, the first and the second loudspeakers are configured to simultaneously reproduce a substantially identical signal. In the multi-channel mode, the first loudspeaker reproduces a first-channel signal and the second loudspeaker reproduces a second-channel signal. The first-channel signal and the second-channel signal can constitute respective portions of a multi-channel signal. Such loudspeaker systems can also have a mode selector configured to select one of the single-channel mode and the multi-channel mode. In some embodiments, such selection can occur in response to one or more detected proximities of another loudspeaker system. Multi-zone loudspeaker systems are also disclosed.

摘要： A microphone assembly includes an acoustic transducer configured to generate an analog signal in response to pressure changes sensed by the acoustic transducer. The analog signal includes frequency components below a threshold frequency. The microphone assembly also includes an integrated circuit electrically coupled to the acoustic transducer and configured to determine a characteristic of frequency components below the threshold frequency, determine whether the characteristic of the frequency components corresponds to a fall event, and generate an output signal in response to a determination that the characteristic of the frequency components corresponds to the fall event. The microphone assembly also includes a housing having an external device interface with electrical contacts. The acoustic transducer and the integrated circuit are disposed within the housing. The integrated circuit is electrically coupled to contacts of the external device interface.

摘要： A sound masking system according to the invention is disclosed in which one or more sound masking loudspeaker assemblies are coupled to one or more electronic sound masking signal generators. The loudspeaker assemblies in the system of the invention have a low directivity index and preferably emit an acoustic sound masking signal that has a sound masking spectrum specifically designed to provide superior sound masking in an open plan office. Each of the plurality of loudspeaker assemblies is oriented to provide the acoustic sound masking signal in a direct path into the predetermined area in which masking sound is needed. In addition, the sound masking system of the invention can include a remote control function by which a user can select from a plurality of stored sets of information for providing from a recipient loudspeaker assembly an acoustic sound masking signal having a-selected sound masking spectrum.
