Abstract

The utility model relates to a rectangular or runway-typed bracket of a receiver or a loudspeaker, which comprises a plastic bracket (1) and a circular magnetizer (2). A boss, a ring-shaped magnetic conductive plate (21) and a ring-shaped magnet (22) are arranged at the middle part of the magnetizer (2) and the magnetizer (2) and the magnetic conductive plate (21) are connected into an integral body by the ring-shaped magnet (22); the boss extends in the ring-shaped magnet (22); the periphery of the magnetizer (2) is an edgefold (23) which has the same thickness with an extension surface of the magnetizer (2) and the periphery of the magnetic conductive plate (21) is also an edgefold (24) which has the same thickness with the magnetic conductive plate (21).The magnetizer (2) and the magnetic conductive plate (21) are inlaid on the plastic bracket (1) by respective edgefold (23, 24). An acoustic hole (3) is arranged on the plastic bracket (1). The bracket has the advantages that a good combination degree between the plastic bracket and the magnetizer is good and the shedding uneasily occurs in the direction of the height.

Description

The support of rectangle or racetrack receiver or loud speaker

Technical field

The utility model relates to a kind of support improvement of electro-acoustic element, the specifically a kind of rectangle of minor axis below 15mm or support of racetrack receiver or loud speaker of being suitable for.

Background technology

Along with such as more and more miniaturization of mobile phone terminal, ultra-thinization, employed receiver or loud speaker (loudspeaker) in this Terminal Type, more and more rectangle or racetrack used, therefore, the dimensional requirement to the support short-axis direction of receiver or loud speaker is more and more littler.The support of existing receiver or loud speaker comprises magnetic conductor (also claiming pole, T iron), plastic cement frame, toroidal magnet and annular magnetic conductive board, the plastic cement frame is provided with hole, described magnetic conductor periphery is provided with a circle chimb, described chimb is embedded in the described plastic cement frame, and magnetic conductor and plastic cement frame are tightened together.But the support of this structure receiver or loud speaker because short-axis direction is narrower, causes the short-axis direction metallic object to expose, and influences product design and fastness; In addition, existing chimb all is that described magnetic conductor periphery directly is stamped to form, its thickness has only the 1/3-1/2 of magnetic conductor thickness, as everyone knows, the thickness of magnetic conductor is mostly about 0.4mm at present, so the thickness of chimb just has only about 0.2mm, this chimb by 0.2mm thickness is connected with the plastic cement frame, and its fastness is relatively poor.

Summary of the invention

The purpose of the present utility model is: provide a kind of magnetic conductor to combine the support of the good rectangle of firmness or racetrack receiver or loud speaker with the plastic cement frame to society.

The technical solution of the utility model is: the support that designs a kind of rectangle or racetrack receiver or loud speaker, comprise the plastic cement frame, the magnetic conductor of middle part band boss, toroidal magnet and annular magnetic conductive board, described toroidal magnet is clipped between described magnetic conductor and the annular magnetic conductive board, the boss of described magnetic conductor is stretched within toroidal magnet, described magnetic conductor, toroidal magnet and annular magnetic conductive board are embedded on the described plastic cement frame, described plastic cement frame is provided with hole, it is characterized in that: described magnetic conductor and annular magnetic conductive board are that described flanging thickness equates with the thickness of the plane of flattening of magnetic conductor by on the flanging embedding plastic cement frame on the periphery.

Described magnetic conductor is circular, and the flanging of magnetic conductor is two sections arc flangings, is separately positioned on the two ends of long axis direction, and the width of arc flanging is less than diameter of a circle.

Described flanging also can be warpage limit or distortion limit.

Described warpage limit or distortion limit and magnetic conductor plane are greater than the angle of 0 degree less than 90 degree.

The utility model like this, can guarantee magnetic conductor and plastic cement frame bonding strength owing to adopted the flanging identical with magnetic conductor thickness and plastic cement frame to be halved together, and can not make magnetic conductor from the plastic body problem that comes off because the original chimb of appearance is too thin.In addition, be provided with warpage limit or distortion limit at the long axis direction of described magnetic conductor, can guarantee that like this plastic cement frame and magnetic conductor have fine conjugation, short transverse is not easy to come off.
