Abstract

Point source speaker systems are provided. The point source speaker system receives audio input from a device. The system comprises a mountable enclosure, which contains a speaker array. The array includes a substantially forward facing left speaker, a substantially forward facing center speaker, a substantially forward facing right speaker and a horizontally mounted woofer speaker. A woofer tunnel is located behind the left, center and right speakers. The woofer tunnel accelerates woofer sound waves and terminuses at a woofer baffle which leads to a woofer port. The left speaker, center speaker and right speaker may include more than one speaker. One or more of these left speakers and right speakers may be a tweeter. The left speakers receive a left minus right input, the center speakers receive a right plus left input, and the right speakers receive right minus left input.

Claims

1. A point source speaker system, useful in association with an audio device, the point source speaker system comprising:

an enclosure configured to mount a speaker array, wherein the speaker array includes a substantially forward-facing left speaker, a substantially forward-facing center speaker, a substantially forward-facing right speaker, and a horizontally mounted woofer speaker; and

wherein the enclosure includes;

a woofer tunnel configured to accelerate woofer sound waves generated by the woofer speaker, wherein the woofer tunnel is located behind the substantially forward-facing left speaker, the substantially forward-facing center speaker and the substantially forward-facing right speaker; and

a woofer baffle configured to couple the woofer tunnel to a woofer port.

2. The point source speaker system of claim 1, wherein the woofer baffle is a conical volume.

3. The point source speaker system of claim 1, wherein the woofer port is coupled to a forward-facing surface of the enclosure.

4. The point source speaker system of claim 1, wherein the woofer port is coupled to a side-facing surface of the enclosure.

5. The point source speaker system of claim 1, wherein the woofer port is coupled to a top-facing surface of the enclosure.

6. The point source speaker system of claim 1, wherein the woofer port is coupled to a downward-facing surface of the enclosure.

7. The point source speaker system of claim 1, wherein the woofer tunnel has a substantially square cross-sectional profile.

8. The point source speaker system of claim 1, wherein the woofer tunnel has a substantially rectangular cross-sectional profile.

9. The point source speaker system of claim 1, wherein the woofer tunnel has a substantially cylindrical profile.

10. The point source speaker system of claim 1, further comprising a substantially forward-facing left tweeter.

11. The point source speaker system of claim 1, further comprising a substantially forward-facing second center speaker.

12. The point source speaker system of claim 1, further comprising a substantially forward-facing right tweeter.

13. The point source speaker system of claim 10, wherein the left speaker and the left tweeter both receive a left signal in parallel from the audio device.

14. The point source speaker system of claim 11, wherein the center speaker and the second center speaker both receive a center signal in series from the audio device.

15. The point source speaker system of claim 12, wherein the right speaker and the right tweeter both receive a right signal in parallel from the audio device.
