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 speaker assembly, comprising:
- 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;
- 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
- a supporting structure comprising a supporting element that is configured to support a portion of a user, wherein the waveguide is coupled to the supporting structure through a coupling.
A speaker assembly, comprising:
- 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;
- 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
- a supporting structure comprising a supporting element that is configured to support a portion of a user, wherein the waveguide is coupled to the supporting structure through a coupling,
- wherein a cross-sectional area at any point along a length of the first portion of the internal region that extends from the first side of the driver to the first sound opening is at least 80% of the area of the driver.
A method of generating an audible sound, comprising:
- generating haptic vibrations from a speaker assembly at frequencies less than 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 haptic vibrations 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.
