Abstract

Integrated processing of audio/video signals can eliminate unnecessary signal processors and converters without losing the functionality of typical home entertainment system components. The integrated system includes a main player that captures and processes signals digitally, a dummy display, and a dummy speaker. The dummy display may only have a display panel and a panel driver. The dummy speaker may only have a driving unit and no crossover logic. The main player may have a PC architecture and process all signals digitally for outputting signals tailored for the display device and the individual driving units of the dummy speaker. The integrated system may also provide dynamic signal adjustments based on the surrounding environment. The main player may include a storage device and can process media content stored therein to produce supplemental information to provide an optimal audiovisual experience. This supplemental information can be shared among users over a network connection.

Claims

1. A speaker system, comprising:

a plurality of interchangeable speaker modules, wherein each interchangeable speaker module includes a speaker unit.

2. The speaker system of claim 1, further comprising a speaker housing, wherein the plurality of interchangeable speaker modules are removably couplable to the speaker housing.

3. The speaker system of claim 1, wherein each of the plurality of interchangeable speaker modules are removably couplable to one another.

4. The speaker system of claim 1, further comprising a plurality of amplifiers generating speaker driving currents driving the corresponding plurality of interchangeable speaker modules.

5. The speaker system of claim 4, wherein the plurality of interchangeable speaker modules comprise:

a first interchangeable speaker module driven by a first driving current; and

a second interchangeable speaker module driven by a second driving current.

6. The speaker system of claim 5, wherein the first interchangeable speaker module is a woofer adapted for lower frequency speaker driving currents and a second interchangeable speaker module is a tweeter adapted for higher frequency speaker driving currents.

7. The speaker system of claim 6, wherein the plurality of amplifiers comprises a hybrid amplifier, including at least one digital amplifier providing the low frequency speaker driving current to the woofer and at least one analog amplifier providing the high frequency speaker driving current to the tweeter.

8. The speaker system of claim 4, wherein the plurality of amplifiers are analog amplifiers.

9. The speaker system of claim 4, wherein the plurality of amplifiers are digital amplifiers.
