Abstract

The utility model discloses a novel loudspeaker, which comprises a film cushion, a sound film, gaskets, a washer, magnetic steel and T-shaped iron which are arranged in turn. The center part of the T-shaped iron is inserted in the center of the magnetic steel, so as to ensure that the magnetic force in the center of the T-shaped iron is the strongest; the washer and the sound film cushion are respectively provided with an insulating gasket so as to insulate the two; the film cushion is connected with the washer through a screw so as to position the sound film in the center with the strongest magnetic force; the T-shaped iron consists of a column body and a brim which are press-formed; the column body is a hollow shell with an opening on the lower end; and the opening of the column body extends outwards to form the brim. The novel loudspeaker is mainly applied to the aspect of anti-theft loudspeakers for automobiles or other places.

Description

A kind of novel horn

[technical field]

The utility model relates to a kind of novel horn.

[background technology]

Existing loudspeaker have generally comprised plastic tube, sound film, washer, pad and magnet steel and T iron assembles successively, but because T iron generally is made up of at the base plate (also can be described as shade) of cylinder bottom a solid cylinder and punching press, because cylinder is solid, waste material, and increase whole weight; It is punching press that cylinder and base plate are arranged again, has increased technology like this, and punching press also can cause waste when bad, increases cost, has reduced the qualification rate of product.

[utility model content]

The utility model overcome the deficiencies in the prior art and provide a kind of light, save material, convenience, simple in structure and practical novel horn.

In order to solve the technical problem of above-mentioned existence, the utility model adopts following technical proposal:

A kind of novel horn includes T iron, it is characterized in that described T iron is made up of stamping forming cylinder and shade, and described cylinder is the housing that there is opening the lower end of a hollow, the described cylinder opening part formation shade that stretches out.

Aforesaid a kind of novel horn is characterized in that at described shell nozzle place the one convenient inserted sheet of installing being installed, and is provided with an installing hole at inserted sheet.

Aforesaid a kind of novel horn is characterized in that being arranged with two jacks at T iron lower opening place, and described inserted sheet two ends are arranged in the jack.

The beneficial effects of the utility model are: the cylinder and the shade of one, the utility model T iron are stamped to form by an iron plate, are formed in one, and save towards cylinder technology again, save cost; Two, cylinder is a hollow, is not solid, has saved material; Three, be provided with a convenient inserted sheet of installing, be provided with installing hole, like this when the wiring board of assembling loudspeaker, thereby be screwed into the effect of installing hole fixing circuit board with screw at the inserted sheet center in T iron lower opening, easy for installation.
