Abstract: A subwoofer that is enclosed in a housing adapted for tool-less installation and removal on a watercraft using cam-latch mounts on existing vendor mounting locations or on included custom mounting plates. The watercraft subwoofer system includes a waterproof signal and power connector with no tools necessary to connect or disconnect. The down-firing subwoofer acoustically couples the subwoofer to the hollow vehicle hull and increases bass. The enclosure has a passive acoustic radiator to provide increased bass response and pressure equalization when hitting the water or momentarily submerged. The enclosure has marine lights on the rear-facing side. The enclosure also has a one-way pressure valve to release pressure if hitting water at high speeds and becoming submerged. An anti-slip mat is provided on the top of the enclosure to reduce the likelihood of a rider slipping off the rear of the watercraft. Various enclosure shapes may be used.

Abstract: An LED light ring for ceiling mounted speakers having flanged enclosures with flip dogs is presented. The LED light ring is a flat annular transparent or translucent piece that is clamped between the enclosure flange and the ceiling tile and emits RGB LED light radially outward through the LED light ring. The LED light emits from LEDs mounted on a circular electronic circuit board (flexible or not) on the inner circumference of the LED light ring. The circular electronic circuit is coupled to a controller that controls the color, blink rate, and intensity and has firmware for interpreting simple controller commands into complex LED light patterns and sequences. A plurality of light ring equipped loudspeakers may be in communication with a common controller that can create patterns and sequences among the plurality of light ring equipped loudspeakers.

Abstract: A small speaker for panel mounting in a hole as small as seventy five millimeters diameter in which access to the rear of the panel is not required. The small speaker uses spring-loaded flip dogs that are actuated by rotating a sound disperser that is connected to a hollow cylindrical mechanism having gear teeth on its external surface which engage flip dog gears on the top surfaces of the flip dogs. Internally, the hollow cylindrical mechanism has an indentation that supports a speaker baffle which, in turn supports a speaker bushing. A loudspeaker is attached to the speaker bushing near the speaker baffle. Two housing sections attach, spaced apart, to an annular frame on opposing sides and receive the hollow cylindrical mechanism rotationally therein. The flip dogs operate in the spaces between the housing sections. Methods of mounting and dismounting are described.

Abstract: A sleek ceiling speaker having an annular magnetic assembly and annular dust cap through which extends an elongated actuator, which may also be a light pipe. The elongated actuator supports a variable transformer tap which is manually operated by rotating a bottom end of the elongated actuator which is expanded into a sound disperser plug. Changing the transformer tap changes the volume produced by the speaker. The elongated actuator may also support an LED board that provides light to the light pipe and to the transparent or translucent sound disperser plug. Rotating the elongated actuator may also be used to change the lighting. The housing is secured to a ceiling tile by attaching a releasably attachable outwardly extending circumferential flange to a sound funnel that supports the sound disperser.

Abstract: An improved manually operated flip dog mountable ceiling speaker enclosure, for ceiling or other panel installation, has a biased sliding ratchet block that can be latched in place by an extension from a T-handle of an integral actuator rod. The ratchet block is controlled in its sliding motion by alignment rods extending from a vertical portion of a base and slidingly received in alignment bores of the ratchet block. A face of the ratchet block has downward pointing ratchet teeth that engage upward pointing ratchet teeth on a barrel of a flip dog to hold the flip dog in a clamped position. Over time, the biasing springs may lose their strength, but the latching of the ratchet block obviates this problem.
