Abstract
Disclosed herein is a waterproof speaker system for use in residential and commercial applications. The disclosed speaker system is particularly applicable to wet conditions with large temperature changes such as greenhouses, gardens, boats, and other outdoor installations or where traditional speakers are negatively affected by water, temperature changes, and humidity. The waterproof speaker system generally comprises a solid water impermeable cast rear and side casing, and internal front frame member housing the speaker drivers and in some cases a simple electronics or amplification circuit, and a water impermeable front face panel sealed to the front frame member and/or the rear casing to completely enclose the speaker driver from contact with moisture.
Claims9
A waterproof speaker system comprising:
- a. a water impermeable rear casing, cast as a unitary body with a rear panel and side panels substantially orthogonal to the rear panel;
- b. a front frame sealed to the rear casing;
- c. a water impermeable front face panel sealed to a perimeter face of the front frame;
- d. wherein a low frequency first speaker driver is attached to the surface defining the driver void forward of the rear casing and rearward of the front face panel such that the low frequency first speaker driver is not in contact with the front face panel;
- e. wherein a rear surface of the front face panel, a front surface of the front frame, a front surface of the low frequency first speaker driver and an offset edge define an offset void allowing the front face panel to oscillate without contacting the front frame nor the low frequency first speaker driver;
- f. a surface defining an unrestricted-flow port through the rear casing with a volume expanding bladder attached to an interior portion of the unrestricted-flow port;
- and
- g. a speaker wiring fitting sealed to and projecting through the rear casing to provide electrical communication to the low frequency first speaker driver.
A waterproof and hermetically sealed speaker system comprising:
- a. a water and air impermeable rear casing, cast as a unitary body with a rear panel and side panels substantially orthogonal to the rear panel;
- b. a front frame sealed to the rear casing;
- c. a water and air impermeable front face panel hermetically sealed to a perimeter face of the front frame;
- d. wherein a low frequency first speaker driver is attached to the surface defining the driver void forward of the rear casing and rearward of the front face panel such that the low frequency first speaker driver is not in contact with the front face panel;
- e. wherein a rear surface of the front face panel, a front surface of the front frame, a front surface of the low frequency first speaker driver and an offset edge define an offset void allowing the front face panel to oscillate without contacting the front frame nor the first speaker driver;
- f. a surface defining an unrestricted-flow port through the rear casing with a volume expanding bladder attached to an interior portion of the unrestricted-flow port;
- and
- g. a speaker wiring fitting sealed to and projecting through the rear casing to provide electrical communication to the low frequency first speaker driver.
