PLAYBACK CIRCUIT, RECORDING CIRCUIT AND AUDIO CHIP - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240266940 titled 'PLAYBACK CIRCUIT, RECORDING CIRCUIT AND AUDIO CHIP
Simplified Explanation: The patent application describes a playback circuit that includes a digital-to-analog converter (DAC), an amplifying output circuit, and a control circuit. The DAC converts an input playback audio signal into an analog playback audio signal based on a control signal to limit power consumption. The amplifying output circuit generates an output playback audio signal based on the input analog signal and a control signal to limit power consumption. The control circuit generates control signals based on the volume of the input audio signal to manage power consumption of both the DAC and the amplifying output circuit.
- The circuit includes a DAC, an amplifying output circuit, and a control circuit.
- The DAC converts input audio signals to analog signals with controlled power consumption.
- The amplifying output circuit generates output audio signals with controlled power consumption.
- The control circuit adjusts power consumption based on the volume of the input audio signal.
- Overall, the circuit efficiently manages power consumption in audio playback systems.
Potential Applications: 1. Audio playback devices such as speakers, headphones, and sound systems. 2. Consumer electronics like smartphones, tablets, and laptops. 3. Automotive audio systems in cars and vehicles. 4. Professional audio equipment for studios and live performances.
Problems Solved: 1. Efficient management of power consumption in audio playback circuits. 2. Optimization of power usage in various audio devices. 3. Enhanced control over power consumption based on audio volume levels.
Benefits: 1. Improved energy efficiency in audio playback systems. 2. Extended battery life in portable devices. 3. Enhanced audio performance with optimized power consumption. 4. Cost-effective operation of audio equipment.
Commercial Applications: The technology can be utilized in the development of energy-efficient audio devices for consumer electronics, automotive industry, and professional audio equipment markets.
