Speaker with automatic volume control
An example speaker for providing alerts includes: a housing and a cover forming an integrated unit; a microphone configured to sense an ambient noise level; and a processor configured to adjust a volume of the speaker based upon the ambient noise level. A hinge can be positioned between the housing and the cover to allow the cover to be pivoted relative to the housing from a close position to an open position.
1. An apparatus for providing alerts, the apparatus comprising:
a housing and a cover;
a hinge positioned between the housing and the cover to allow the cover to be pivoted relative to the housing from a close position to an open position, thereby maintaining all wiring of the apparatus in a connected state;
an audio device having a driver configured to compress air, the driver being operable in a first configuration as a speaker to provide alerts and operable in a second configuration as a microphone configured to sense an ambient noise level, the driver being positioned in, and fixed relative to, the housing;
a control board including a programmable logic controller data interface programmed to allow third parties to control or monitor the speaker, the control board being positioned in, and fixed relative to, the cover;
a wire electrically connecting the control board to a component positioned in, and fixed relative to, the housing; and
a processor configured to adjust a volume of the speaker based upon the ambient noise level.
2. The apparatus of claim 1 , further comprising a manifold defining a plurality of channels, with each of the channels providing a pathway for air being provided to the driver of the speaker.
3. The apparatus of claim 1 , wherein the processor is configured to allow the apparatus to communicate with a remote computing device.
4. The apparatus of claim 3 , wherein the volume of the speaker is controlled by the remote computing device.
5. The apparatus of claim 3 , wherein the apparatus communicates with the remote computing device using an Internet Protocol communications protocol.
6. The apparatus of claim 1 , wherein the processor is configured to provide data relating to an operating characteristic of the speaker.
7. The apparatus of claim 6 , wherein the operating characteristic is one or more of voltage, current, and temperature.
8. The apparatus of claim 1 , wherein the processor is further programmed to provide an automatic level control for the volume of the speaker.
9. The apparatus of claim 8 , wherein the processor is further programmed to provide one or more automatic level control modes.
10. The apparatus of claim 9 , wherein the automatic level control modes include one or more of:
a linear mode that changes the volume in a linear correlation with the ambient noise level;
a stepped mode that changes the volume in one or more pre-determined steps with the ambient noise level; and
a fixed differential mode that allows a pre-defined sound pressure level differential between the volume and the ambient noise level.
11. The apparatus of claim 1 , further comprising local contact closures that are configured to control the speaker.
12. The apparatus of claim 1 , further comprising a nonincendive circuit.
13. An apparatus for providing alerts, the apparatus comprising:
a housing and a cover forming an integrated unit;
a hinge positioned between the housing and the cover to allow the cover to be pivoted relative to the housing from a close position to an open position, thereby maintaining all wiring of the apparatus in a connected state;
an audio device having at least one component that is operable in a first configuration as a speaker to provide alerts and operable in a second configuration as a microphone configured to sense an ambient noise level, the at least one component being a driver configured to compress air, the driver being positioned in, and fixed relative to, the housing;
a manifold defining a plurality of channels, with each of the channels providing a pathway for air being provided to the driver of the speaker;
a control board including a programmable logic controller data interface programmed to allow third parties to control or monitor the speaker, the control board being positioned in, and fixed relative to, the cover;
a wire electrically connecting the control board to a component positioned in, and fixed relative to, the housing; and
a processor configured to:
adjust a volume of the speaker based upon the ambient noise level;
provide data relating to an operating characteristic of the speaker, the operating characteristic being one or more of speaker pressure level, voltage, current, and temperature; and
allow the apparatus to communicate with a remote computing device.
14. The apparatus of claim 13 , wherein the volume of the speaker is controlled by the remote computing device.
15. The apparatus of claim 13 , wherein the apparatus communicates with the remote computing device using an Internet Protocol communications protocol.
16. The apparatus of claim 13 , wherein the processor is further programmed to provide one or more automatic level control modes, wherein the automatic level control modes include one or more of:
a linear mode that changes the volume in a linear correlation with the ambient noise level;
a stepped mode that changes the volume in one or more pre-determined steps with the ambient noise level; and
a fixed differential mode that allows a pre-defined sound pressure level differential between the volume and the ambient noise level.
