Claims24
An audio enhancement system for improving audio performance of a consumer electronic device with an acoustic signature and a transducer, comprising:
- a parametrically configurable processing (PCP) block;
- and
- a digital driver (DD) block in signal communication with the PCP block and the transducer of the consumer electronic device;
- wherein the PCP block is configured to receive an input audio signal from the consumer electronic device and to form an enhanced signal from the received input audio signal,
- wherein the DD block is configured to receive the enhanced signal from the PCP block, to derive an audio output signal from the enhanced signal, and to output the audio output signal to the transducer, and
- wherein the PCP block is configured to substantially compensate for the acoustic signature of the consumer electronic device with the enhanced signal.
A method for enhancing audio experience of a consumer electronic device having an acoustic signature, comprising:
- determining the acoustic signature of the consumer electronic device;
- formulating an audio enhancement system from the acoustic signature;
- and
- integrating the audio enhancement system into the consumer electronic device.
The method in accordance with claim 16, further comprising adding psychoacoustic and/or real-bass enhancement functionality to the audio enhancement system.
A method for enhancing audio performance of a consumer electronic device, comprising:
- integrating an audio enhancement system into the consumer electronic device, wherein the audio enhancement system comprises a parametrically configurable processing block configured to receive an input audio signal from the consumer electronic device and to form an enhanced signal from the received input audio signal;
- analyzing the consumer electronic device during a manufacturing, quality control and/or product testing process to determine a set of optimization parameters;
- updating the parametrically configurable processing block of the audio enhancement system with the optimization parameters.
A system for enhancing an audio output of a consumer electronic device having an acoustic signature and a transducer, the system comprising:
- a remote subsystem, comprising a parametrically configured processing (PCP) block, the PCP block configured to accept an input audio signal and produce an enhanced audio signal;
- and
- an integrated subsystem in signal communication with the remote subsystem, comprising a digital driver (DD) block, configured to receive the enhanced audio signal and deliver an output signal to the transducer on the consumer electronic device;
- wherein the remote system is implemented remotely from the consumer electronic device, and
- wherein the integrated subsystem is implemented in the consumer electronic device.
