Abstract
The utility model relates to slim small-bore horn art, particularly the slim washer structure of one.Comprise washer body (1), described washer body central is provided with T iron stopper slot (2), with internal thread (3) in described T iron stopper slot, described internal thread coordinates with the external screw thread of T iron root, described T iron stopper slot is to described washer body posterior protrusion, and the both sides, front of described washer body are provided with several magnet limited posts.In the utility model, the thickness of described washer body is less than 0.2mm, and external diameter is less than 10mm.The utility model arranges a T iron stopper slot on existing washer body, and this stopper slot is by two kinds of modes and T ferropexy, and one is fixed by screw thread, welded besides by scolding tin, and fixing is like this more firm; In addition four magnet limited posts are set at the opposite side of washer body, can realize fixing closely with magnet.
Description
Technical field
The utility model relates to slim small-bore horn art, particularly the slim washer structure of one.
Background technology
Loudspeaker are loud speaker again, be a kind of very conventional electro-acoustic transducer device, divide moving-coil type (electrodynamic type), condenser type (electrostatic), piezoelectric type (crystal or pottery), electromagnetic type (compressed spring type), electric ion type and pneumatic type loudspeaker etc. by transducing mechanism and structure.
The most common most typical be that cone formula loudspeaker are also called moving-coil type loudspeaker it is made up of three parts:
1. vibrational system, comprises taper cone, voice coil loudspeaker voice coil and centring disk etc.;
2. magnetic circuit system, comprises adopted magnet, magnetic conductive board and field stem etc. forever;
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, just produce the magnetic field with tone currents change, the magnetic field of this magnetic field and permanent magnet interacts, and voice coil loudspeaker voice coil is axially vibrated, because horn structure is simple, bass is plentiful, tonequality is soft, bandwidth, but efficiency is lower.
The magnet of these loudspeaker and washer (spring shim) are fixed in horn bracket, and existing horn bracket is divided into: magnetic after-tacks glue water type support (not being with rivet type) and separation type support (the independent type of rivet).
Existing washer product due to very thin (similar very thin that disk), so be easy in utilization process distortion; Because this product is very little thin again, so when electrogalvanizing, if product has water to cause product to stick together, thus plating is not got on, and magnet, T iron and washer are fixed insecure, causes loudspeaker to produce noise.
Utility model content
The technical problem that the utility model solves is to provide a kind of slim washer product structure, increases washer intensity, is convenient to and magnet and T ferropexy.
For achieving the above object, the utility model provides a kind of slim washer structure, comprise: comprise washer body, described washer body central is provided with T iron stopper slot, with internal thread in described T iron stopper slot, described internal thread coordinates with the external screw thread of T iron root, and described T iron stopper slot is to described washer body posterior protrusion, and the both sides, front of described washer body are provided with several magnet limited posts.
Further, the thickness of described washer body is less than 0.2mm, and external diameter is less than 10mm.
Further, the dorsal part of described magnet limited post is provided with glue groove.
The beneficial effects of the utility model are: the utility model arranges a T iron stopper slot on existing washer body, and this stopper slot is by two kinds of modes and T ferropexy, and one is fixed by screw thread, welded besides by scolding tin, and fixing is like this more firm; In addition four magnet limited posts are set at the opposite side of washer body, can realize fixing closely with magnet.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing and preferred embodiment, a kind of slim washer structure, comprise washer body 1, described washer body central is provided with T iron stopper slot 2, with internal thread 3 in described T iron stopper slot, described internal thread coordinates with the external screw thread of T iron root, and described T iron stopper slot is to described washer body posterior protrusion, and the both sides, front of described washer body are provided with several magnet limited posts 4.In the utility model, the thickness of described washer body is less than 0.2mm, and external diameter is less than 10mm.
Traditional magnet and washer body, directly be connected together by gluing, this kind of plane adhesion mode, along with the vibration of loudspeaker after glue is air-dry, just slight crack is there will be between long-time magnet and washer, and then be separated, in order to solve the problem, the dorsal part of described magnet limited post is provided with glue groove 5.Viscose glue in this glue groove is relatively some more, and the viscose glue of Jiao Caochu is thus relatively firm, and four glue grooves make can be balanced between washer body and magnet fixing, can by washer body and magnet fixation by injecting viscose glue in glue groove.
According to the technical solution of the utility model, the utility model arranges a T iron stopper slot on existing washer body, and this stopper slot is by two kinds of modes and T ferropexy, and one is fixed by screw thread, welded besides by scolding tin, and fixing is like this more firm; In addition four magnet limited posts are set at the opposite side of washer body, can realize fixing closely with magnet.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
Claims (3)
1. a slim washer structure, comprise: comprise washer body, described washer body central is provided with T iron stopper slot, with internal thread in described T iron stopper slot, described internal thread coordinates with the external screw thread of T iron root, described T iron stopper slot is to described washer body posterior protrusion, and the both sides, front of described washer body are provided with several magnet limited posts.
2. slim washer structure according to claim 1, is characterized in that, the thickness of described washer body is less than 0.2mm, and external diameter is less than 10mm.
