Description
Technical Field
The utility model relates to a speaker field especially relates to a speaker U iron structure.
Background
The U-shaped iron structure of the traditional loudspeaker (single magnet, three magnet or multiple magnet) is simple, the loudspeaker can be formed by stretching, bending and cutting, but some complicated U-shaped iron structures (washer is assembled in the middle to form an upper U-shaped structure and a lower U-shaped structure) like the double-diaphragm loudspeaker are formed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a speaker U iron structure for solve the not enough of prior art.
In order to solve the above problems, the technical solution of the present invention is:
the utility model provides a speaker U iron structure, includes the middle part for having U iron and the china department that runs through the cavity, the tip of U iron be provided with the ascending U type mouth of a plurality of breachs, the both sides wall of U type mouth is provided with rim charge portion, the lower part at U type mouth is fixed to the lower part of this rim charge portion, the thickness of rim charge portion is 0.2 ~ 0.4mm, is provided with a plurality of china departments fixed part on the china department, the china department fixed part is then installed in U type mouth, its rim charge portion can be through bending and pushing down the china department fixed part under the exogenic action.
The washer is arranged in the middle of the U-shaped iron.
The washer fixing part of the washer is provided with a washer projection part extending outwards.
The total length of the two rim charge parts of the U-shaped opening is smaller than the width of the U-shaped opening.
The U-shaped iron consists of two parallel straight line parts and arc parts symmetrically arranged, and the U-shaped opening is positioned on the arc parts.
The arc parts are respectively provided with two U-shaped openings which are symmetrically arranged.
The utility model has the advantages that: the edge material part (thickness 0.2-0.4 mm) of the U-shaped iron notch is directly pressed through the matching die head, so that the edge material part of the U-shaped iron notch and the washer are integrated into a whole to play a fixing role, the structure and the complexity of the large shortening process improve the production efficiency, and more economic benefits are created for companies.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic structural view of the present invention;
in the figure: 1-U iron, 2-washer, 11-U-shaped opening, 12-rim charge part, 13-linear part, 14-arc part, 21-washer fixing part and 22-washer projection part.
Detailed Description
The following describes the present invention in further detail with reference to the accompanying drawings.
Referring to the drawings 1-2, the utility model discloses a middle part is for having U iron 1 and the china department 2 that runs through the cavity, U iron 1's tip be provided with the ascending U type mouth of a plurality of breachs 11, U type mouth 11's both sides wall is provided with rim charge portion 12, the lower part at U type mouth 11 is fixed to the lower part of this rim charge portion 12, the thickness of rim charge portion 12 is 0.2 ~ 0.4mm, be provided with a plurality of china departments fixed part 21 on the china department 2, china department fixed part 21 then installs in U type mouth 11, its rim charge portion 12 can be through bending and pushing down china department fixed part 21 under the exogenic action.
More preferably, the washer 2 is arranged in the middle of the U-shaped iron 1.
More preferably, a washer protruding portion 22 extends outwards from the washer fixing portion 21 of the washer 2.
More preferably, the total length of the two marginal portions 12 of the U-shaped opening 11 is smaller than the width of the U-shaped opening 11.
More preferably, the U-shaped iron 1 is composed of two parallel straight line parts 13 and arc parts 14 symmetrically arranged, and the U-shaped opening 11 is positioned on the arc parts 14.
More preferably, the circular arc portions 14 are provided with two U-shaped openings 11, and are symmetrically arranged.
In practical application, the thickness of rim charge portion 12 is 0.2-0.4 mm, rim charge portion 12 has certain elasticity and toughness, be provided with a plurality of china department fixed parts 21 on china department 2, china department fixed part 21 is then installed in U type mouth 11, its rim charge portion 12 can be through bending and pushing down china department fixed part 21 under the exogenic action, consequently, install china department 2 back on the U iron, then through the exogenic force with rim charge portion 12 buckling, just can direct fixed part china department 2, and need not adopt technological means such as riveting or welding, such structure and the big complexity that shortens technology, and the production efficiency is improved, simultaneously, china department 2 installs the middle part position at U iron 1, after installing like this, make china department 2 all the same to the position from top to bottom, be convenient for the installation of double-diaphragm speaker.
The above-mentioned specific implementation is the preferred embodiment of the present invention, can not be right the utility model discloses the limit, any other does not deviate from the technical scheme of the utility model and the change or other equivalent replacement modes of doing all contain within the scope of protection of the utility model.
