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, the loudspeaker of easy to assemble, easy care, 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 washer is provided with the clearance position of assembling usefulness towards a side of magnet.
Be respectively arranged with location hole or detent on described sound larynx, vibrating membrane 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 the location notch on the vibrating membrane and be arranged on the 4th location hole on the washer, and the 4th location hole and clearance position are coaxially set.
Be provided with the pad of ring-type between described washer and the vibrating membrane.
The 4th location hole place that described pad is positioned at washer is provided with the 3rd location notch or location hole.
Described washer is provided with positioning boss towards pad one side, and the 4th location hole is opened in the positioning boss, and the shape of the shape of positioning boss and the 3rd location notch or location hole adapts.
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.
Washer claims magnetic conduction sheet again.
Because being used to connect the screw of sound larynx, vibrating membrane and washer occurs different in size through regular meeting; cause at last that the gap appears in fitting surface between washer and the magnet; and then influence the acoustics of loudspeaker; so the utility model is provided with clearance position at washer towards magnet one side; this clearance position provides a fitting allowance value; when the length of screw is less than or equal to the height of positioning boss; just do not need this clearance position; when the length of screw during greater than the height of positioning boss; clearance position just plays a role, and is close to the fitting surface of guaranteeing washer and magnet.
The utility model prevents that the assembling injustice from appearring in washer and vibrating membrane, pad, and second location notch or location hole is set that this pad can adopt plastics or asbestos to make on pad in order to cooperate the positioning boss on the washer.
The utility model so reduced the thickness of washer, has also reduced cost of manufacture owing to be provided with clearance position at washer towards magnet one side simultaneously; After sound larynx, vibrating membrane, pad and washer connect as one by screw, can realize assembling fast by the defining flange and the shell of ring-type on the sound larynx, and then boost productivity, reduce cost of manufacture.
The utlity model has simple and reasonable, cost of manufacture is low, the characteristics of easy to assemble and easy care.
