Abstract

The present invention sets out to solve the problems above by presenting a dual-mode speaker system for acoustic reproduction. The dual-mode speaker system for acoustic reproduction presents a system with high-energy conversion efficiency and provides flexibility between an active speaker driver and other radiators, improved sound quality, a larger range of low frequency sounds, and the capability to improve audio frequency playback range in small-scale audio environments. A dual-mode acoustic radiator speaker system is provided having an enclosure with a plurality of openings, an active speaker driver having a first motor assembly and a dual-mode radiator having a second motor assembly. In some embodiments, the dual-mode acoustic radiator speaker system further comprises one or more passive radiators adjoined to the enclosure. Next, within the dual-mode acoustic radiator speaker system a power supply is connected to the electronic signal processing and amplification system.

Claims (16)

1. A dual-mode acoustic radiator speaker system for acoustic reproduction comprising:

an enclosure having internal volume;

an active speaker driver having a first motor assembly, wherein the active speaker driver is adjoined to the enclosure;

a dual-mode radiator having a second motor assembly, wherein the dual-mode radiator is adjoined to the enclosure;

a power supply;

an electronic signal processing and amplification system positioned inside or outside the enclosure and connected to the power supply, the electronic signal processing and amplification system connected to and configured to drive the active speaker driver and the dual-mode radiator enabling the dual-mode radiator to perform as a passive radiator and as a second active speaker;

wherein the electronic signal processing and amplification system further comprises:

a first signal amplifier connected to the active speaker driver;

a second signal amplifier connected to the dual-mode radiator;

a mode circuit having a first switch, a second switch and a resistor; wherein the mode circuit is configured to operate a mode of the dual-mode radiator.

2. The system of claim 1 , wherein the enclosure further comprises a port protruding through the enclosure.

3. The system of claim 1 , wherein the first switch is disconnected from the second signal amplifier, such that the first switch controls the dual-mode radiator to perform as the passive radiator.

4. The system of claim 1 , wherein the second switch is in parallel with the dual-mode radiator and therein controls the dual-mode radiator to perform as the passive radiator with electrical dampening.

5. The system of claim 1 , wherein the electronic signal processing and amplification system further comprises an input device configured to receive an input.

6. The system of claim 1 , wherein the dual-mode acoustic radiator speaker system further comprises a plurality of dual-mode radiators.

7. The system of claim 1 , further comprising one or more passive radiators.
