Abstract
Addressable amplified speakers assembly, and method for addressing the same, suitable for any permanent or temporary public address paging application. Amplified speakers assembly may incorporate VHF and UHF radios to provide wireless, one-way paging from a few feet to many miles away. These speakers can be added to any existing radio system with minimal effort or cost. The need for routing signal cable is eliminated, greatly reducing installation costs. Each speaker can be programmed for individual, group, or all-page access via DTMF or 2-Tone coding (up to 8 different addresses). The volume of each speaker can also be controlled remotely.

An amplified speaker assembly comprising:
- an audio speaker,
- an amplifier which drives said audio speaker;
- a volume control circuit which controls sound volume output from said audio speaker;
- an input configured to receive a signal;
- and
- a programmable microprocessor responsive to said signal;
- wherein said programmable microprocessor commands said volume control circuit to adjust said sound volume output from said audio speaker in accordance with said signal.
An amplified speaker assembly comprising:
- an audio speaker;
- an amplifier which drives said audio speaker;
- an input configured to receive a signal;
- and
- a programmable microprocessor responsive to said signal;
- wherein said input is configured to receive said signal via a hardwire connection to a source of said signal;
- and
- said microprocessor activates said amplifier in reply to a detection of a page closure and detection of correct programmed code in said signal received at said input.
An amplified speaker assembly comprising:
- an audio speaker;
- an amplifier which drives said audio speaker;
- an input configured to receive a signal;
- and
- a programmable microprocessor responsive to said signal;
- wherein said input comprises a receiver configured for wireless reception of said signal;
- and
- said microprocessor activates said amplifier in reply to a detection of a carrier detect and sub-audible detect, and detection of correct programmed code in said signal received at said input.
A method for addressing an amplified speaker assembly comprising an audio speaker, an amplifier which drives said audio speaker, a volume control circuit which controls sound volume output from said audio speaker, an input configured to receive a signal, and a programmable microprocessor responsive to said signal, said method comprising:
- receiving said signal via a hardwire connection to a source of said signal;
- and
- adjusting said sound volume output from said audio speaker in accordance with said signal.
