Abstract
A cabinet for housing a round, open-back, cone type driver. The cabinet includes a barrel-shaped internal wall that has first and second opposing open ends and a substantially circular cross section. The diameter of the cross section at the midpoint of the internal wall is greater than the diameter of the internal wall at the opposing open ends. A mounting ring is secured to the internal wall between approximately a front quarter and a back quarter of the cabinet, configured for receiving the driver.
Claims15
A cabinet for housing a round, open-back, cone type driver, comprising:
- a barrel-shaped internal wall comprising first and second opposing open ends and a substantially circular cross section, wherein the diameter of the cross section at the midpoint of the internal wall is greater than the diameter of the internal wall at the opposing open ends;
- and
- a mounting ring, configured for receiving the driver, secured to the internal wall at a position offset from the center of the cabinet such that the center of the cone portion of the driver aligns with the center of the cabinet.
(canceled)
A method for simulating a genuine infinite baffle, comprising:
- providing a barrel-shaped internal wall comprising first and second opposing open ends and a substantially circular cross section, wherein the diameter of the cross section at the midpoint of the internal wall is greater than the diameter of the internal wall at the opposing open ends;
- providing a mounting ring configured for receiving a round, open-back, cone type driver;
- securing the mounting ring to the internal wall at a position offset from the center of the cabinet such that the center of the cone portion of the driver aligns with the center of the cabinet;
- and
- using the driver to convert an electrical audio signal to sound pressure waves that are directed to the first and second opposing ends.
