Abstract
The utility model provides a folding diaphragm high pitch loudspeaker, in particular to a novel high pitch loudspeaker improved on the basis of a widely-known 'Haier' high pitch loudspeaker. The high pitch loudspeaker has the structure that the surface of a folding insulating film base body is compounded with a strip voice coil, then the folding insulating film base body is arranged in a closed magnetic circuit composed of a U-shaped heel piece, a front magnetic conduction plate and a magnet, two adjacent faces of a diaphragm relatively move to push air to make sound. Compared with a traditional Haier loudspeaker, the folding diaphragm high pitch loudspeaker has the characteristics of small volume, high sensitivity, low distortion factor, simple production technology, low cost, non magnetism and the like, and can be widely applied in various loudspeaker box systems.
Description
One. technical field
The folding vibrating diaphragm high pitch loudspeaker of the utility model is applied to belong to the electroacoustic techniques field in all kinds of sound box systems.
Two. background technology
Haier's loud speaker (seeing accompanying drawing 1) of the Oscar doctor Heil invention of the U.S. in 1973, with its unique tune, the excellent tone color and the very low distortion factor obtain good reputation widely, but because of its complex structure, volume greatly, not antimagnetic, price is high can not be widely used.Improve at above problem the present invention.
Three. summary of the invention
Innovative content of the present utility model mainly changes above-mentioned Haier loud speaker into antimagnetic interior magnetic design, effectively raises magnetic circuit efficient, reduces small product size, reduces production costs, and reaches antimagnetic requirement.Make product can access better popularization and application.
To achieve these goals, the utility model provides a kind of folding vibrating diaphragm high pitch loudspeaker, form by vibrating diaphragm, vibrating diaphragm support, preceding magnetic conductive board, U type yoke, bar magnet, magnet holder, sound-absorbing bar, damping fin, gasket seal, magnetic conductive board, U type yoke, bar magnet are formed closed magnetic circuit before described, vibrating diaphragm, vibrating diaphragm support are formed the vibrating diaphragm group, are positioned in the magnetic gap of closed magnetic circuit.
Wherein, can be preferred: vibrating diaphragm be by compacting one deck aluminium foil or Copper Foil on the resistant to elevated temperatures insulation film sheet, voice coil loudspeaker voice coil and be flexed into many folding shapes and form in chemical etching then, and described vibrating diaphragm is installed in becomes the vibrating diaphragm group on the vibrating diaphragm support.
Wherein, can be preferred: magnetic conductive board has the marking shape window more than 2 before described, and the shape of described marking shape window can be a rectangle, ellipse, runway shape.
Wherein, can be preferred: U type yoke be to be bent by magnetic conduction irony plate stamping to form, and also available polylith plate is spliced.Closed and open can be made in the back.
Wherein, can be preferred: bar magnet be located with magnet holder, and many same polarities are evenly distributed forms antimagnetic closed magnetic circuit with U-shaped yoke, preceding magnetic conductive board.
Wherein, can be preferred: fill with the sound-absorbing bar between adjacent bar magnet, separate with damping fin between magnet surface and the vibrating diaphragm.
The utlity model has following technique effect:
1.U type yoke (accompanying drawing 4) forms the U-shaped of one by magnetic conduction irony plate stamping, handling ease, cost are low.
2. the vibrating diaphragm back is added with the damping pad, can effectively improve the harmful acoustic reflection in diaphragm back.
3. this utility model can be made back sealing and open different modes.When adopting back sealing mode, the sound-absorbing bar through optimal design, and is filled in the rectangular closed space that forms between U type yoke and each magnetic stripe, can effectively control and promote the low side frequency response.See accompanying drawing 6.
