[technical background] is present, still there are not relevant technical literature publication and report similar techniques scheme, do not have production marketing yet or be used for actual product, the most approaching technical patent of the present invention 00238074.9 " broadband coaxial loudspeaker ", the patent scheme is that the bass vibration component is housed on the basin frame, and the high pitch vibration component is installed on the T iron core column.
The present invention is obviously different with this patented technology scheme, is a kind of tweeter of technological innovation.The present invention adopts homology sound basin to make radiator.
Support auxiliary system of the present invention adopts common middle pitch basin frame and the design of sound basin radiator, has been completely free of the constraint of conventional loudspeakers surface plate radiation, brings higher propagation efficiency and high frequency to extend and littler phase distortion to loud speaker.
Sound basin radiation mode and Squawker specific among the present invention are in same vertical direction, and promptly zero level separates, and it is identical that the sound wave that high pitch and middle pitch are sent arrives the time of audience's ear, and it is leading to have solved common high pitch sound wave dexterously, the phenomenon of phase place confusion.As shown in the figure: A figure is the unit mounting means of common audio amplifier, and its horizontal separation degree is d; B figure points to the floor because of horizontal separation causes ZDP axle (Zero Delay Plane zero-lag plane) from axle; C figure is that common audio amplifier is put upside down, and its ZDP axle points to ceiling; D figure, E figure is the compromise mode of most Hi-Fi audio amplifier; F figure is the audio amplifier that zero level separation homology sound basin radiation high pitch loudspeaker has been installed.
Described zero level homology sound basin radiation high pitch loudspeaker has improved the propagation efficiency of sound wave, and let us figures out more music detail.
[goal of the invention] the objective of the invention is to, and provides a kind of zero level to separate homology sound basin radiation high pitch loudspeaker, has been completely free of bad phenomenon such as traditional high pitch sound wave is leading, phase place is chaotic, propagation efficiency is low.
[technical scheme] accompanying drawings is as follows: see Fig. 1, Fig. 1-a, Fig. 1-b, Fig. 1-c, Fig. 1-d, relate to a kind of agent structure feature and separate homology sound basin radiation high pitch loudspeaker by the zero level that the magnetic circuit system of improved support auxiliary system, vibrational system and inner magnetic structure constitutes.
Described support auxiliary system is made up of terminal (6), support (7), pad (8), basin frame (9), sound basin radiator (10), outstanding limit (11), pressure ring (12), sound-absorbing cotton balls (14), location damper (15).Described sound basin radiator (10) is made the radial cone of special hyperbola, according to clean slurry, soaking paste, pulping, pull an oar, drag for processing steps such as system, moulding, gluing, punching, side cut, check and make; Also can make compound cone, overall plastic awl basin, glass fibre awl basin, the fine awl of charcoal basin, metal foaming awl basin.Described basin frame (9) available metal iron material, aluminium or synthetic plastic are made.Described location damper (1 5) is made the circular wave sheet with foamed plastic, rubber, cotton adhesive plaster, thin,tough silk matter adhesive plaster.Described support (7) can be selected papery for use, and plastic hot is pressed into sheet.The available papery cotton yarn of described pad (8), foamed plastic etc. are hot pressed into laminar.Terminal available metal electric conducting material copper, iron or alloy are processed into.The available papery of pressure ring (12), foamed plastic etc. are made.Described outstanding limit (11) is hot pressed into ring-type by rubber, cloth, foamed plastic.State sound basin radiator (10) and upward mount outstanding limit (11) inner port reverse side in the large port front.Described outstanding limit (11) external port reverse side mounts basin frame (9) large port front.Described pressure ring (12) mounts front, outer, outstanding limit (11).Described sound basin radiator (10) portlet outer down mounts the interior edge of damper (15), location.Described location damper (15) outer mounts basin frame (9) bottom platform rank.Described sound-absorbing cotton balls (14) is mounted on T sections (3) front between pronunciation sound film (13) and the voice coil loudspeaker voice coil (16).Mount with polyurethane kind glue, phenolic mixing glue or other glue.
Described vibrational system is made up of pronunciation sound film (13), voice coil loudspeaker voice coil (16).Described sound film can select for use materials such as silk, cloth to make.Metallic conduction materials such as the available copper cash of described voice coil loudspeaker voice coil (16), aluminum steel, copper cover aluminum turn to.Available round line voice coil loudspeaker voice coil, lenticular wire voice coil loudspeaker voice coil or the exoskeletal tread flaking voice coil loudspeaker voice coil that skeleton is arranged of described voice coil loudspeaker voice coil (16).The framework material of described voice coil loudspeaker voice coil (16) can be selected making such as papery, plastics, metal for use.Described voice coil loudspeaker voice coil (16) is made according to doing skeleton, gluing, coiling, baking and curing, depoling coating removal, warding off the tin processing, and processing steps such as quality inspection are made.Described voice coil loudspeaker voice coil (16) skeleton upper edge mounts the interior edge of sound film (13).Its collar extension of described pronunciation sound film (13) mounts support (7) front between two parties along reverse side.Described pad (8) is mounted on above the support (7) of sound film (13).
Described inner magnetic structure magnetic circuit system is made up of antimagnetic lid (1), secondary magnetic (2), T sections (3), main magnetic (4), upper conduction magnetic board (5).The even weighing apparatus of described main magnetic (4) is installed between upper conduction magnetic board (5) and the T sections (3).The coiler part of described T sections (3) suit voice coil loudspeaker voice coil (16).Described secondary magnetic (2) mounts T sections (3) bottom centre.Center, described antimagnetic lid bottom mounts secondary magnetic (2) bottom.Described upper conduction magnetic board (5) and basin frame (9) bottom platform rank riveted.Described upper conduction magnetic board (5) and T sections (3) and antimagnetic lid (1) are made for general permeability magnetic material, can select iron-nickel alloy, Tie Gufanhejin for use, industrial blunt iron, mild steel A
