Abstract
The utility model relates to a loud speaker box frame, belonging to the technical field of loud speaker box equipment. The loud speaker box frame adopts hard foamed plastic to make into an integral structure. The outer surface, the front panel, the left panel, the right panel and the inner surface of the top panel of a loud speaker box are smooth and hard, and the inner surface of a back panel is a soft cambered surface. Circular arc transitional connection is formed at a connecting position between the panels.
Description
The utility model relates to the structure of sound box bodies, belongs to the stereo set technical field.
Sound box bodies in the stereo set, general adopt woodenly, the polylith plank with following closely or mode such as glue is spliced, bonding making, is cubic hexahedron, front panel, back backplate, Left-Hand Panel, right panel, top panel, bottom panel are arranged, establish high and low sound speaker hole on the front panel and fall the sound hole.Form wedge angle between panel and the panel, it is strong to produce standing wave, because the adhering and sealing quality is not enough, produces gas leak phenomenon sometimes, influences tonequality.The back backplate of audio amplifier is often because the hardness height needs the rear cushion sound-absorbing material at audio amplifier.Existing wooden speaker production complex process, inefficiency, cost height.
The purpose of this utility model is a kind of good airproof performance, psycho-acoustical quality height will be provided, manufacture the efficient height, the sound box bodies that cost is low.
The purpose of this utility model is achieved in that sound box bodies comprises front panel 1, Left-Hand Panel 2, right panel 3, top panel 4, bottom panel 5 and back backplate 6, high and low sound bellmouth orifice 7 is arranged on the front panel 1, fall sound hole 8, it is characterized in that sound box bodies is a monolithic construction, with rigid foamed is material, panel is established arc transition with the interior angle place that is connected between the panel, and the inner surface of the outer surface of sound box bodies and front panel, Left-Hand Panel, right panel, top panel, bottom panel is smooth hard.The inner face of back backplate is a cambered surface, and plate matter is softer.The plate in-core of audio amplifier has hole, and reinforcement can be established in the inboard of plate, strengthens the intensity of audio amplifier.Adopt inside and outside mould, once be filled in the mold cavity, make sound box bodies rigid foamed.
The utility model is simple in structure, and is easy to manufacture, and cost is low, and good integrity is seamless, and the square corner phenomenon is compared with existing sound box bodies, and reproduction frequency range is wide, the output sound pressure level height, and sound pressure frequency characteristic is good.
Accompanying drawing is a structural representation of the present utility model, 1 front panel, 2 Left-Hand Panels among the figure, and 3 right panels, 4 top panels, 5 bottom panels, 6 back backplates, 7 high and low sound bellmouth orifices, 8 are the sound hole.
Narrate case study on implementation of the present utility model below in conjunction with accompanying drawing.
Adopt inside and outside mould, internal mold adopts many grid plans control inflation moulds, is material with hard foamed polyurethane, in mix glass fibre and pour in the mold cavity, after the foamed polyurethane sclerosis,, can take out easily the internal mold venting.At the top layer of inside and outside mould liner thermoplastics sheet, the inside and outside smooth surface of sound box bodies after the demoulding.Sound box bodies becomes monolithic construction, and it is the back backplate 6 of cambered surface that front panel 1, Left-Hand Panel 2, right panel 3, top panel 4, bottom panel 5, inner face are arranged, and high and low sound bellmouth orifice 7 is arranged on the front panel and fall sound hole 8.
