Description
Technical field
The utility model relates to a kind of electromagnetic screen, and particularly a kind of shielding case that is applied in moving iron type loud-speaker or the receiver belongs to electroacoustics and micromachine and learns the field.
Background technology
The problem of shielding case in order to separate decision bit vibrating diaphragm system and to be attached thereto that is used for moving iron type loud-speaker or receiver in the market, generally adopt along the shielding case hull outside and push to inwall, to form circle or semicircle salient point, and by these to the salient point of inwall projection as detent mechanism, the positioning film systems approach.Although this kind method is relatively simple for structure, the Project Realization difficulty is very large, the first, and these circular or its end faces of semicircular salient point namely all can't guarantee it is the plane usually with the contact-making surface of vibrating diaphragm system, therefore can't locate fully as location vibrating diaphragm system the time; Second, these salient points all are usually after the shielding case housing has been finished, and process one by one moulding by rear road again, have larger accumulated error, be difficult to guarantee all salient points all in same level, this has produced very large impact to the positional accuracy of diaphragm system again.The deficiencies such as in a word, the diaphragm system detent mechanism ubiquity complex process in the existing shielding case, accumulated error are large, locating effect is not good.
Summary of the invention
The utility model is intended to propose a kind of shielding case for moving iron type loud-speaker or receiver, its fault of construction that it has combined the advantage of traditional shielding case design and reasonably avoiding, can effectively solve the difficult problem that the vibrating diaphragm system is difficult to locate in existing moving iron type loud-speaker or the receiver manufacturing process, and the structure-improved realizability is strong, thereby has overcome deficiency of the prior art.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of shielding case for moving iron type loud-speaker or receiver, by housing, interior step, open recess and through hole four parts form, it is characterized in that, described shielding case is an overall structure, described interior step place described shielding case inwall and around around, described interior ledge surface is consistent apart from shielding case bottom surface horizontal range.
Further, described open recess is positioned at described shielding case housing front end edge edge; Described through hole is positioned at described shielding case housing rear end face middle part.
Preferably, described shielding case uses aluminium, stainless steel, brass or permalloy at manufactured materials.
Described shielding case is concrete when being applied in described moving iron type loud-speaker or the receiver, and described interior step is used for locating the vibrating diaphragm system of described moving iron type loud-speaker or receiver, and is fixedly connected with the vibrating diaphragm system.
Described shielding case is concrete when being applied in described moving iron type loud-speaker or the receiver, and the open recess of described shielding case is as described moving iron type loud-speaker or receiver speaking terminal; The through hole of described shielding case is as described moving iron type loud-speaker or the outlet of receiver holding wire.
Compared with prior art, the utility model has the advantage of:
(1) on structure, the adding of innovation place the interior step mechanism of inner walls, well solve vibrating diaphragm location, the assembling difficult problem of moving iron type loud-speaker or the medium-term and long-term existence of receiver manufacturing process, significantly increased the manufacturability of Related product, reduced production cost;
(2) on technique, place the interior step manufacturing process realizability of inner walls stronger, and cost is not high, and great market popularization value is arranged.
