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.

Abstract: An amplifier-resident device for protecting amplifiers and loudspeakers from shock transient audio signals from dropped microphones that may use either an amplifier control signal from the microphone or a sequential sampling of the incoming audio (optionally switchable) to determine if a microphone drop, or other shock transient, is occurring. If a shock transient is occurring, the device blocks audio signal access to the amplifier. The audio signal goes through a delay line to allow processing time for detecting a shock transient and switching the shock transient audio signal out of the path to the amplifier. The delay may be variable. The device may be integral to the amplifier or may plug into a microphone jack of the amplifier, allowing use with legacy amplifiers. In an embodiment, the device may store safe, predetermined audio signals to send to the amplifier during, and in place of, a shock transient.

Abstract: A handheld vapor dispenser with rapidly interchangeable vapor tubes extending outside of the dispenser housing. A first exemplary embodiment uses a battery and a timing circuit to volatize the vapor-producing material and a positive air pressure source, such as a squeeze bulb, to expel the vapor from the tube. A second exemplary embodiment is rechargeable and has multiple vapor tubes in parallel spaced-apart proximity extending from the housing. A recharging station for multiple vapor dispensers that also provides vapor tube storage and access is disclosed. A third exemplary embodiment couples positive air pressure to the air inlet of an electronic cigarette to expel vapor from the mouthpiece for flavoring drinks. A dispensing tube that sealingly attaches to the mouthpiece is also disclosed. Additional embodiments are disclosed.

Abstract: A speaker system having internal and external static and dynamic constituent speaker parts at least partially coated with a hydrophobic coating to prevent water or condensation accumulations that would interfere with performance. Objects associated with the speaker, such as a speaker grill, power supply, speaker support, or speaker enclosure may also be at least partially coated with a hydrophobic coating to prevent water or condensation accumulations that would interfere with performance.

Abstract: A speaker system having internal and external static and dynamic constituent speaker parts at least partially coated with an amathophobic coating to prevent dust accumulations that would interfere with performance. Objects associated with the speaker, such as a speaker grill, power supply, speaker support, or speaker enclosure may also be at least partially coated with an amathophobic coating to prevent dust accumulations that would interfere with performance.

Abstract: A manually operated flip dog mountable ceiling speaker enclosure, for ceiling or other panel installation, provides a plurality of flip dogs mounted tangentially on an annular flange around an opening of a speaker can and operated by either pulling on an actuator to create a cam-driven rotation to a radial alignment and a downward dog movement to a ratcheted clamping position, or by first rotating the manual actuator to rotate the dog and then pulling the actuator to pull the dog down into a ratcheted clamping position. Ratchet points on the dog are urged into ratchet points on a wall by a releasable biasing member. Three embodiments are illustrated.
