Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional audio broadcasting systems require manual setting of power ratings for public addressing speakers, which is inefficient and may lead to improper configuration.
Innovation Solution
An apparatus and method for automatically recognizing wattage tap settings using a controller, wattage tap circuit, and pulse signals to identify the appropriate audio output level of public addressing speakers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual setting of power ratings is used for public addressing speakers, then device complexity is reduced, but productivity and configuration accuracy deteriorate
Solution Approach 1:
The system performs self-identification of wattage tap settings through automatic detection. The controller sends test signals through the wattage tap circuit and analyzes the returned signals to automatically determine the current wattage setting, eliminating the need for manual configuration while maintaining system simplicity.
Solution Approach 2:
The system uses feedback mechanisms where the controller sends test signals through the wattage tap circuit and receives returned signals to identify the current setting. This closed-loop feedback enables automatic recognition of the wattage tap position without manual intervention.
2Measurement precision
If manual setting of power ratings is used, then ease of operation is maintained, but measurement precision and configuration accuracy worsen
Solution Approach 1:
The system automatically identifies wattage tap settings through self-testing. The controller sends test signals and analyzes the returned signals to determine the current wattage setting, ensuring accurate measurement without requiring user intervention or manual configuration.
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated electrical testing system. Instead of manually setting power ratings, the system uses electronic test signals and signal analysis to automatically detect and identify the current wattage tap setting, improving precision while maintaining ease of use.

AI summary
Apparatus and methods recognize a wattage tap setting of an audio device. The apparatus includes an audio load, wattage tap circuit, and controller. The wattage tap circuit has a particular wattage setting corresponding to an audio output level of the audio load. The controller sends a pulse signal to the wattage tap circuit and receives a return signal from the wattage tap circuit in response to the pulse signal. The controller identifies the particular wattage setting of the wattage tap circuit based on the return signal.
