Abstract
Embodiments described herein relate to a dipole speaker assembly. The dipole speaker assembly includes a cabinet with a first end and a second end. A driver is positioned within the cabinet and directed towards an end of the cabinet. Positive sound waves emit through the end of the cabinet in which the driver is directed towards and negative sound waves emit through the opposite end of the cabinet to create localized audible regions near the two ends of the cabinet that dissipate further away from the cabinet.
Claims25
A method of generating an audible sound, comprising:
- generating an audible sound from a speaker assembly, wherein the speaker assembly comprises:
- a waveguide comprising:
- a first sound opening positioned at a first end of the waveguide;
- and
- a second sound opening positioned at a second end of the waveguide;
- and
- a driver coupled to the waveguide, wherein the driver comprises a diaphragm that separates an internal region of the waveguide disposed on a first side of the driver from a second side of the driver, and
- wherein a sound pressure level (SPL) of the generated audible sound decreases by an amount greater than the inverse square law as a distance from the first sound opening or the second sound opening increases.

A method of generating an audible sound, comprising:
- generating an audible sound from a speaker assembly at frequencies less than 200 Hz, wherein the speaker assembly comprises:
- a waveguide comprising:
- a first sound opening positioned at a first end of the waveguide;
- and
- a second sound opening positioned at a second end of the waveguide;
- and
- a driver coupled to the waveguide, wherein the driver comprises a diaphragm that separates an internal region of the waveguide disposed on a first side of the driver from a second side of the driver, and
- wherein
- the frequencies of the generated audible sound comprise at least a first frequency, and
- a length of the internal region, which extends between the first side of the driver and the first opening, is at least a quarter wavelength of the first frequency.

A method of generating an audible sound, comprising:
- generating an audible sound from a speaker assembly into a listening environment, wherein the speaker assembly comprises:
- a waveguide comprising:
- a first sound opening positioned at a first end of the waveguide;
- a second sound opening positioned at a second end of the waveguide;
- and
- an internal region that extends between the first sound opening and the second sound opening;
- and
- a driver coupled to the waveguide, wherein the driver comprises a diaphragm that separates a first portion of the internal region disposed on a first side of the driver from a second portion of the internal region disposed on a second side of the driver, and
- wherein
- the generated audible sound comprises frequencies no greater than 200 Hz, and
- the audible sound generated by the driver causes the driver to generate positive sound waves that are provided to the listening environment from the first side of the driver and negative sound waves that are provided to the listening environment from the second side of the driver, and
- the magnitude of the sound pressure level (SPL) of the positive sound waves and negative sound waves exiting the speaker assembly into the listening environment are about equal when they exit the speaker assembly.
9 more elements
A method of generating an audible sound, comprising:
- generating an audible sound from a speaker assembly into a listening environment, wherein generating the audible sound comprises:
- delivering from a first sound-generating source a first portion of the audible sound to the listening environment;
- and
- delivering from a second sound generating source a second portion of the audible sound to the listening environment,
- wherein
- the generated audible sound comprises frequencies no greater than 200 Hz, and
- the magnitude of the sound pressure level (SPL) of the first portion of the audible sound when exiting the first sound generating source into the listening environment is about equal to the magnitude of the SPL of the second portion of the audible sound when exiting the second sound generating source into the listening environment.
4 more elements
A method of generating an audible sound, comprising:
- generating an audible sound from a speaker assembly into a listening environment, wherein the generated audible sound comprises:
- positive sound waves and negative sound waves that are within a frequency range that is no greater than 200 Hz;
- and
- generating the audible sound further comprises:
- delivering, by a first sound-generating source, the positive sound waves to the listening environment;
- and
- delivering, by a second sound-generating source, the negative sound waves to the listening environment,
- wherein the magnitude of the sound pressure level (SPL) of the positive sound waves exiting the speaker assembly into the listening environment is substantially equal to the magnitude of the SPL of the negative sound waves exiting the speaker assembly into the listening environment.
