Abstract
The systems, methods, and devices disclose a transducer system located in a room or in an area to provide an alert to one or more persons. The transducer system includes at least a receiver, a processor and a speaker. The receiver receives an alert message sent from an alarm system or from another transducer system. The processor is configured to determine, from a plurality of notification messages, a notification message based on the alert event indicated by the alert message. Each of the plurality of notification messages corresponds to a different alert event, and each of the plurality of notification messages includes information to vibrate a speaker according to a different pre-determined vibration pattern. The speaker is moveable to generate a vibration pattern according to the determined notification message to inform a person about the alert event, wherein the speaker generates the vibration pattern in a low-frequency range.
