Abstract
The invention discloses a novel inductance coil structure which comprises a coil holder, a coil wound on the coil holder and a metal shell arranged on the coil. Openings allowing pins of the coil to be led out are arranged on the metal shell. Compared with inductance coil structures in the prior art, the novel inductance coil structure has the advantages that outside electromagnetic interference can be effectively shielded, noise interference like howling is reduced, frequency response curve is enabled to be smoother, and feel of a listener is improved.
Description
Technical field
The present invention relates to a kind of inductance coil, particularly a kind of novel inductor loop construction.
Background technology
Inductance coil is a kind of device that utilizes the principle of electromagnetic induction to carry out work, mainly coil holder and the coil that is wound on coil holder, consists of.Along with making rapid progress of electronic technology, the application of inductance coil is more and more also that extensively correspondingly, inductance coil miscellaneous is also arising at the historic moment.
In current inductance coil, be limited to the simple structure of coil holder and coil, in concrete use, coil is easy to be subject to extraneous interference, the electromagnetic interference that the parts such as such as chip form it etc.And when this inductance coil is applied in audio product, this interference will develop into the noise jamming phenomenon of uttering long and high-pitched sounds etc., upset frequency response curve, cause voice output unstable of audio product, affect daily use.
Therefore,, for these above-mentioned problems, we need a kind of inductance coil that can overcome them badly.
Summary of the invention
Object of the present invention is exactly for the problems referred to above, and a kind of novel inductor loop construction that can effectively shield external interference is provided.
To achieve these goals, the invention provides following technical scheme: novel inductor loop construction, it comprises:
Coil holder;
Coil, it is wound on described coil holder;
Metal-back, it is arranged on described coil, offers the opening of drawing for the pin of described coil on described metal-back.
Preferably, between described coil and described metal-back, be also provided with glue layer.
Preferably, in described glue layer, there is Magnaglo.
Preferably, described metal-back is that iron nickel material is made.
Preferably, described metal-back is along on the half area that is axially sheathed on described coil outer wall of described coil.
Preferably, described metal-back is along on the half area that is circumferentially coated on described coil outer wall of described coil.
Preferably, described opening is that corresponding described pin is opened in the through hole on described metal-back outer wall.
Preferably, described opening is along the strip hole on the described metal-back outer wall of being axially opened in of described metal-back.
Adopt the beneficial effect of above technical scheme to be: novel inductor loop construction of the present invention has mainly comprised coil holder, coil and metal-back, it is compared to the structure of inductance coil of the prior art, can effectively shield extraneous electromagnetic interference, reduce the phenomenon of noise jamming such as uttering long and high-pitched sounds, make frequency response curve more level and smooth, improve hearer's impression.
