Abstract

An improved and cost effective speaker/controller system that is configured to allow a single master controller to have connectivity, communicability and control over multiple speaker/controllers in a cluster of speaker/controllers, through a communications connection with a single master speaker/controller in the cluster.

Claims

1. A system for extending functionality of a single room intercom/control system to another room, the system comprising:

a control module communicatively coupled to a master speaker system;

a slave speaker system interface communicatively coupled to the control module;

a slave speaker system comprising;

an interface to the slave speaker system interface;

an analog speaker;

a microphone; and

one or more control interfaces;

wherein the master speaker system is coupled to a master controller through a single PoE port and, wherein the control module is configured to;

register the slave speaker system with the master controller;

obtain commands received at the master speaker system intended for the slave speaker system; and

control the operation of the slave speaker control system in accordance with the received commands through the slave speaker interface; and

the slave speaker interface is configured to provide power from the single PoE port to the slave speaker system.

2. The system of claim 1, wherein upon the control module receiving an audio signal directed to the slave speaker system, the control module transmits the audio signal to the analog speaker of the slave speaker system through the slave speaker system interface.

3. The system of claim 1, wherein upon the control module receiving a control signal directed to a component coupled to on of the slave speaker control interfaces, the control module transmits a signal to the slave speaker to actuate the control interface.

4. The system of claim 1, wherein the slave speaker system interfaces to a panic button through one of the one or more control interfaces and in response to receiving a signal indicating that the panic button has been actuated, the slave speaker system sends a signal to the control module through the slave speaker system interface indicating that the panic button has been actuated.

5. The system of claim 1, wherein the slave speaker system interfaces to a wall plate through one of the one or more control interfaces and, wherein the wall plate includes a microphone and an actuation button, and in response to an actuation of the actuation button, a signal is sent to the slave speaker system and, the slave speaker system sends a signal to the control module through the slave speaker interface to initiate a call.

6. The system of claim 5, wherein the communications between the master controller and the master speaker system conforms to the INFORMACAST protocol.

7. The system of claim 6, wherein the call initiation is a SIP call.

8. The system of claim 1, wherein the communications between the master controller and the master speaker system conforms to the INFORMACAST protocol.

9. The system of claim 1, wherein the communication between the slave speaker interface and the master controller conforms to the INFORMACAST protocol.

10. The system of claim 9, wherein the slave speaker interface can register the slave speaker for INFORMACAST broadcasts and as a SIP endpoint.

11. The system of claim 1, wherein the master controller is configured to monitor the amount of current drawn from the PoE and to limit the operation of the master speaker system and the slave speaker system to prevent the current draw from exceeding a threshold level.

12. The system of claim 1, wherein the slave speaker system includes one or more single pole double throw (SPDT) relays and, the action of the control module obtaining commands received at the master speaker system intended for the slave speaker system comprises obtaining a command to actuate one of the SPDT relays;

and the action of the control module controlling the operation of the slave speaker control system in accordance with the received commands through the slave speaker interface comprises creating a command to actuation the SPDT relay and sending it to the slave speaker through the slave speaker interface.

13. The system of claim 12, wherein the commands received from the master controller conform to the INFORMACAST protocol.

14. The system of claim 13, wherein the command created by the control module conforms to a proprietary protocol.

15. The system of claim 1, wherein the slave speaker system interfaces to a wall plate through one of the one or more control interfaces and, wherein the wall plate includes a jack for receiving an audio source, and in response to activating sound reinforcement, a signal is sent to the slave speaker system and, the slave speaker system sends a signal to the control module through the slave speaker interface to provide notice of the event.

16. The system of claim 15, wherein the control module determines that the audio source can be delivered to the slave speaker system and creates a command to configure the slave speaker system to play the audio and sends the command to the slave speaker system through the slave speaker interface.

17. The system of claim 15, wherein the control module determines that the audio source cannot be delivered to the slave speaker system because a higher priority broadcast is currently active.

18. The system of claim 15, wherein the control module determines that the audio source can be delivered to the slave speaker system and creates a command to configure the slave speaker system to play the audio and cancels any currently played audio sources then sends the command to the slave speaker system through the slave speaker interface.

19. The system of claim 1, wherein the master controller is configured to monitor a processing load and to limit the operation of the master speaker system and the slave speaker system if the processing load is above a threshold level.

20. The system of claim 1, wherein the slave speaker system interfaces to a wall plate through one of the one or more control interfaces and, wherein the wall plate includes an audio input jack and an actuation button, and in response to plugging an audio source into the audio input jack and an actuation of the actuation button, the slave speaker system sends a signal to the control module through the slave speaker interface to initiate the control module sending a configuration command to the slave speaker system to enable an audio signal from the audio source to be rendered by the slave speaker system.
