Abstract
Novel methods and systems for coordinating sound to both internal and external speakers for a device is disclosed. The audio signal is distributed among the internal and external speakers and aligned so that signals going to the internal speakers are aligned with signals going to the external speakers.
Claims23
A method for enhancing an audio signal for a device with at least one internal speaker and at least one external speaker, the method comprising:
- distributing the audio signal to the at least one internal speaker and the at least one external speaker;
- and
- aligning timestamps for the distributed audio signal such that signals for the at least one internal speaker aligns with signals for the at least one external speaker.

A device comprising:
- an audio input;
- a microphone;
- at least one internal speaker;
- at least one connector for external speakers;
- a wireless communications module;
- and
- a processor;
- wherein the device is configured to:
- decode an audio signal from the audio input producing decoded audio;
- determine connection statuses of the external speakers both connected to the at least one connector and connected by wireless communications module;
- perform cooperative playback control based on the connection statuses;
- determine locations of the external speakers both connected to the at least one connector and connected by wireless communications module;
- perform dynamic adjustment for the external speakers based on the locations;
- perform multi-channel mixing based on the decoded audio, the cooperative playback control, and the dynamic adjustment producing a mixed signal;
- perform crossover configuration on the mixed signal producing a crossover signal;
- perform signal distribution on the crossover signal among the external speakers and internal speakers producing a distributed signal;
- and
- perform time alignment for the distributed signal for the external speakers and internal speakers.
