Abstract
A loudspeaker comprises a shell, a sound throat, a vibrating diaphragm wound with coils, a washer, a magnet and T-shaped ion, wherein the T-shaped iron is a cap-shaped structure formed by one-time stamping. The T-shaped iron is provided with more than two locating bosses formed by stamping, wherein the locating bosses are arranged annularly. The external diameter of the locating boss is smaller than or equal to the internal diameter of the magnet. The other side of the magnet is connected with the washer. A ring-shaped spacer is arranged between the washer and the vibrating diaphragm; and the sound throat, the vibrating diaphragm, the spacer and the washer are respectively provided with a locating hole or a locating groove and are connected into a whole by a bolt sequentially passing through the locating hole or the locating groove. In the utility model, by arranging the iron or steel washer and the T-shaped iron respectively at two sides of the magnet, the magnetic flux strength is enhanced, and the sound effect is improved; furthermore, the washer, the spacer, the vibrating diaphragm and the sound throat are connected into a whole, and fast assembly is finally realized by a limiting flange and the shell on the sound throat, thus improving production efficiency and reducing manufacturing cost.
Description
Technical field
The utility model relates to a kind of loudspeaker.
Background technology
Common loudspeaker comprise shell, sound larynx, the vibrating membrane that is wound with coil, washer, magnet and T iron, and a kind of with the shake loudspeaker of basin of one-body molded hemisphere as disclosing among the Chinese patent literature CN2410839Y, it is by the basin that shakes, the basin frame plays ripple, washer, magnet, T iron, voice coil loudspeaker voice coil is formed.This loudspeaker are when assembling, and operation is many, and cost of manufacture is also than higher.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, cost of manufacture is low, easy-to-dismount loudspeaker, to overcome weak point of the prior art.
A kind of loudspeaker by this purpose design comprise shell, sound larynx, the vibrating membrane that is wound with coil, washer, magnet and T iron, it is characterized in that T iron is the cap-like structure of a drawing.
Described T iron is provided with the positioning boss through drawing.
Described positioning boss is more than two, the ring-type setting.
The external diameter at described positioning boss place is less than or equal to the internal diameter of magnet.
Described magnet opposite side and washer join.
Be provided with the pad of ring-type between described washer and the vibrating membrane, be respectively arranged with location hole or detent on sound larynx, vibrating membrane, pad and the washer, screw after passing location hole or detent successively fuses it.
Described location hole or detent be respectively first location hole that is arranged on the sound larynx, be arranged on second location hole or location notch on the vibrating membrane, be arranged on the 3rd location notch or location hole on the pad, and be arranged on the 4th location hole on the washer.
Described sound larynx is provided with the defining flange of ring-type, defining flange is provided with more than one groove, the inboard of shell is provided with more than one positive stop lug boss vertically, the below of positive stop lug boss is provided with the positioning step of ring-type, and the distance between positive stop lug boss and the positioning step is more than or equal to the thickness of defining flange.
