Description

A kind of improvement horn bracket

Technical field

The utility model relates to speaker electronics field, in particular to one improvement horn bracket.

Background technology

Loudspeaker are loud speaker again, are a kind of common conventional electro-acoustic transducer devices, according to transduction principle, loudspeaker are divided into moving-coil type, condenser type, piezoelectric type, electromagnetic type, electric ion type and pneumatic type etc.The most common typically paper disc formula loudspeaker are also called moving-coil type loudspeaker, and it is made up of three parts: 1, vibrational system, comprises taper paper disc, voice coil loudspeaker voice coil and centring disk etc.; 2, magnetic circuit system, comprises permanent magnet, magnetic conductive board and field stem etc.; 3, auxiliary system, comprises support, terminal block, flanging and dust cap etc.When being in the voice coil loudspeaker voice coil in magnetic field and having tone currents to pass through, will produce the magnetic field with tone currents change, the magnetic field interaction of this magnetic field and permanent magnet, makes voice coil loudspeaker voice coil vibrate along direction of principal axis, because horn structure is simple, bass is plentiful, tonequality is soft, bandwidth, but efficiency is lower.The magnet of these loudspeaker and spring shim (washer sheet) are fixed in horn bracket, and existing horn bracket is divided into: viscose glue water type support (not being with Liu Ding type) and separation type support (the independent type of Liu Ding); Wherein, in prior art, the support assembly technology of viscose glue water type is complicated, and cost is high, and the dust of glue in dry run in easy absorbed air, formed thread, cause the fraction defective of product high, in addition, easily occur in gluing process that concentricity is partially askew inaccurate, and due to gluing fastness deficiency, causing voice coil loudspeaker voice coil easily to produce noise in magnetic gap, fraction defective promotes.

Summary of the invention

The utility model provides a kind of improvement horn bracket, and object is to provide that a kind of assembling is simple, firm, good concentricity, and cost is low, can solve the viscose glue water type support problem such as gluing insecure in process of production.

For achieving the above object, a kind of improvement horn bracket is provided according to the utility model, comprise support, magnet and washer sheet, support, magnet and washer sheet are installed together successively, the front middle part of support has a circle one-level L-type shell fragment, the rear middle part of magnet has and the position of one-level L-type shell fragment and all corresponding one-level L-type lockhole of number, and the front middle part of magnet has a circle secondary L-type shell fragment, and there is the secondary L-type lockhole corresponding with the position of secondary L-type shell fragment and number at the rear middle part of washer sheet.

The beneficial effects of the utility model: by increasing the cooperation between L-type shell fragment and L-type lockhole between two between parts, make mutually to clamp between parts, can not misplace because of Long-Time Service, improve the quality of product, side by side which adds the fastness that magnet is connected with washer sheet, in addition, because the position of L-type shell fragment and L-type lockhole is all one to one, improve concentricity, also ensure that installation is convenient.

Accompanying drawing explanation

In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below:

Fig. 1 is structural representation of the present utility model;

Fig. 2 is stereogram of the present utility model;

Fig. 3 is support Local map of the present utility model.

In accompanying drawing, 1 is support, and 2 is magnet, and 3 is washer sheet, and 4 is one-level L-type shell fragment, and 5 is secondary L-type shell fragment, and 6 is one-level L-type lockhole, and 7 is secondary L-type lockhole.

Embodiment

Below in conjunction with the accompanying drawing in the utility model, be clearly and completely described the technical scheme in the utility model, obviously, described is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all belongs to the scope of the utility model protection.

Below enforcement of the present utility model is described in detail by reference to the accompanying drawings, as shown in Figure 1, the utility model provides a kind of improvement horn bracket and comprises support 1, magnet 2 and washer sheet 3, support 1, magnet 2 and washer sheet 3 are installed together successively, as shown in FIG. 2 and 3, Fig. 3 is the sectional view of support 1, the front middle part of support 1 has a circle one-level L-type shell fragment 4, the rear middle part of magnet 2 has and the position of one-level L-type shell fragment 4 and all corresponding one-level L-type lockhole 6 of number, the front middle part of magnet 2 has a circle secondary L-type shell fragment 5, there is the secondary L-type lockhole 7 corresponding with the position of secondary L-type shell fragment 5 and number at the rear middle part of washer sheet 3, the position of L-type shell fragment and L-type lockhole is all one to one, such workman is just very easy to directly be placed in corresponding L-type lockhole at different levels by L-type locking plate at different levels, then each parts are installed together according to order, install and fast convenient, and can not misplace because of Long-Time Service, improve the quality of product, increase the fastness of product.

The above, content of the present utility model is not limited to cited by embodiment, and those of ordinary skill in the art take the conversion of any equivalence to the utility model scheme by reading the utility model specification, be claim of the present utility model and contain.
