Abstract:
PROBLEM TO BE SOLVED: To provide a loudspeaker cabinet including a mechanism for conversion of a translational actuation control in a first direction into a translational movement of at least one first latch in a second direction different from the first direction.SOLUTION: A loudspeaker cabinet 2 includes a device for mechanical connection to another cabinet and/or a device 8 for adjusting an angle formed between the cabinet 2 and the another cabinet. The connection device includes a mechanism for conversion of a translational actuation control in a first direction into a translational movement of at least one first latch in a second direction different from the first direction. The angle adjustment device includes an element 8 the length of which in an operating position adjusts said angle and is determined according to a position of a rotary component 10.
Abstract:
A system and method for reducing baffle vibration includes balancing an inertial force generated by two or more moving diaphragms and balancing an acoustic pressure acting on a housing supporting the two or more moving diaphragms such that a net force acting on the baffle is substantially zero. The acoustic force acting on the housing may be balanced independently of the inertial force balance. In another configuration, the acoustic force acting on the housing may be balanced by a non-zero net inertial force.
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that a ceiling pan is undesirably detached from the rear face of a ceiling material when the conventional auxiliary device for fitting having the ceiling pan for rigidly fitting a ceiling-embedded type speaker system to a ceiling is applied to the ceiling where a structure protrudes upward from the rear face of a ceiling material and that the ceiling-embedded speaker system cannot rigidly be fitted even if the ceiling material and the ceiling pan are clamped by a clamping piece of the ceiling-embedded speaker system. SOLUTION: The auxiliary device for fitting ceiling-embedded speaker system 10 is provided with a ceiling reinforcing member 11 and a long member 21. The ceiling reinforcing member 11 has a planar part 12 and an erect part 14 formed to erect from the planar part 12. The erect part 14 can take: a sliding state where it can slide in a vertical direction with respect to the long member 21 and can be displaced; and a fixed state where the erect part 14 can be fixed so that it cannot be displaced in the vertical direction with respect to the long member 21.
