Abstract: An audio filtering and power extraction apparatus for filtering out audio signal and extracting power from a combined signal and direct-current power line, with an input configured to couple to a combined signal and direct-current power line, a filtering extractor system functionally coupled to the input, a DC sensing switch circuit, and a second order low-pass filter functionally coupled to the DC sensing switch circuit, the second order low-pass filter including, an inductor, a capacitor and resistor in series with each other, and an output functionally coupled to an output of the filtering extractor system and through which output extracted power is provided.

Abstract: A mount, mount assembly, and speaker mount. That includes: a mount body with flange; a tower assembly including: a trigger, a dog; a bias member biasing the dog towards the mount body; a path guide guiding the dog along the tower assembly. The path guide allows/forces the dog to be oriented according to: a first orientation wherein the foot is pointed directly towards the mount body and substantially aligned with the tower assembly, and a second orientation wherein the foot is not so pointed and aligned such that the toot does interfere with travel of the mount through an aperture when the dog is in a second position that is spaced closer to the mount body than the first position. The dog changes between positions by operation of the bias member and not by a screw.

Abstract: There is a speaker mount, comprising: a flange; a support member coupled to the flange and having an elevated region spaced therefrom and a closer region closer to the flange than the elevated region, the closer region including a mating structure; and a tab assembly movably coupled to the support member. The tab assembly including: a tab; a coupling member that couples to the mating structure of the support member; and a spacing mechanism coupled to each of the tab and the coupling member that selectably changes an effective spacing between the tab and the coupling member such that the change in effective spacing results in a change in effective distance between the tab and the flange.

Abstract: A mount, speaker mount, mount assembly, and method of disengagement thereof including a speaker baffle; a support member; a movable tab with a finger that extends away from the support member and/or shaped to engage with a surface when the speaker mount is installed, thereby causing the tab to tip relative to the support member. Each of the tab and the support member include mating teeth that, when engaged to each other when the tab tips due to the finger engaging with a surface, prevent travel of the tab from the closer region to the elevated region. There is an aperture through the baffle that provides access to apply pressure to a bottom of the tab to allow for an object to be inserted therein to disengage the mating teeth.

Abstract: A speaker mount, assembly, and method of disengagement including a flange that circumscribes a perimeter of the mount. The speaker mount includes a support member coupled to the flange. The speaker mount includes a tab moveably coupled to the support member. The speaker mount includes a tab bias member functionally coupled to the tab. The speaker mount includes a path guide functionally coupled to the tab and to the support member. The path guide includes a vertical pathing and a rotational pathing that is substantially orthogonal to the vertical pathing. The speaker mount includes a blocking member functionally coupled to the tab such that in a blocking mode the blocking member obstructs free movement of the tab along the path guide and in a free mode does not obstruct.
