Abstract
The magnetic conductive seat includes a seat body which is fabricated with processing method provided by the present invention. The present state of the seat body can be finished through forming and cutting process with an invagination space in it as well as a ring groove with narrow and deep slot is set at the joining place of the invagination space on the seat body and internal wall surface in the seat body. This is one body structure of loadspeaker magnetic conductive seat.
Description
Technical field
The present invention relates to a kind of loud speaker magnetic conductance seat and processing method thereof, particularly a kind of processing method thus can make the method for producing of loud speaker magnetic conductance seat formation integrative-structure, i.e. integrated structure of loudspeaker magnetic conductance seat and processing method thereof.
Background technology
The loud speaker magnetic conductance seat is one of key component of decision speaker performance, and the interior cannelure that must will offer the narrow groove of a zanjon of this loud speaker magnetic conductance seat, for vibrating membrane displacement start, and because on the loud speaker magnetic conductance seat, offer dark 5mm～10mm, the narrow groove of the zanjon of wide 1.6mm～3.0mm, it is the bottleneck of traditional diamond-making technique, make in two formula modes so conventional loudspeakers magnetic conductance seat (seeing also Figure 1 and Figure 2) is many, in it is divided into, after outer seat two parts complete respectively, again the two is utilized suitable engagement means to be combined into one, and in utilizing, the difference of outer seat diameter forms cannelure.
Yet the loud speaker magnetic conductance seat that uses this kind mode to make, because of engagement means utilizes the mode of riveted more, not only manufacturing speed is slow, cost is high for it, and its two riveted spare between must have the gap, and this gap can cause permeability to reduce, and then influences speaker performance.Therefore,, just can improve permeability, more improve the performance of loud speaker if can eliminate the gap.
Summary of the invention
Main purpose of the present invention is to overcome the deficiencies in the prior art and defective, utilizes suitable processing method, by the means of cutting, in order to the loud speaker magnetic conductance seat of the structure that is made into one.
For reaching above-mentioned purpose, the invention provides a kind of integrated structure of loudspeaker magnetic conductance seat processing method, comprise the following steps: forming step: make predetermined pedestal aspect with suitable means; Cutting step: in pedestal, carry out the ring-type cutting with proper implements, make the cannelure that has a narrow and deep slot in this pedestal, and allow these pedestal central authorities be formed with a column, and possess the integrative-structure of suitable spacing with the periphery wall.
Suitable means in described this forming step can be forging or punch forming or other equivalent forming method.
Instrument in described this cutting step be one in airtight foreign side do not have escape to consider to be worth doing still can discharge in the space cutting scrap cutter.

Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with drawings and Examples.
See also Fig. 3 and shown in Figure 4, be stereoscopic of the present invention and generalized section, as shown in the figure, integrated structure of loudspeaker magnetic conductance seat of the present invention, it includes a pedestal 1, this pedestal 1 is by the made default form of suitable manufacture method, in it and have a recessed space 3, and recessed space 3 on this pedestal 1 and internal face 11 intersections in the pedestal 1, offer the cannelure 5 of a narrow and deep slot, and make formation one column 13 in its recessed space 3, so just form the loud speaker magnetic conductance seat of integrative-structure.
See also shown in Figure 5, be manufacturing processing method schematic flow sheet of the present invention, as shown in the figure, the loud speaker magnetic conductance seat of above-mentioned integrative-structure uses following manufacturing processing method to make, it is mainly finished by two steps, at first be forming step a, it is after form the loud speaker magnetic conductance seat of integrative-structure behind the cutting step b; Wherein,
Forming step a: make predetermined pedestal 1 aspect with suitable means; These suitable means can forging or punch forming or other equivalent forming method.
Cutting step b: in pedestal 1, carry out the ring-type cutting with proper implements, make the cannelure 5 that has a narrow and deep slot in this pedestal 1, and allow these pedestal 1 central authorities be formed with a column 13, this column 13 is just possessed cannelure 5 width spacings with base vivo wall face 11, so that be sheathed on vibrating membrane (not shown) on loud speaker magnetic conductance seat 1 column 13, by this cannelure 5 and axially start of column 13.
In addition, instrument described in this cutting step a is one outside airtight in the side space, still can discharge the cutter of cutting scrap, this cutter design has the blade at the suitable oblique angle of a tool, in order to the scrap in the guide cuts process, in cutter, concentrate, and scrap is discharged via through hole designed on it, therefore, according to this processing method cooperate again can be outside airtight the cutter of chip removal in the side space, the loud speaker magnetic conductance seat of the structure that can be made into one, and the loud speaker magnetic conductance seat of making by this kind method, in the airtight recessed space 3 of pedestal 1, cutting at one time is finished the cannelure 5 of narrow and deep slot, and so can make whole pedestal is the single-piece form that one is finished, and does not have the shortcoming that traditional method for making loud speaker magnetic conductance seat has the joint clearance, and more can make magnetic conduction efficient reach 100%, with effective raising usefulness.
By the above detailed description of preferred embodiments, hope can be known description feature of the present invention and spirit more, and above-mentioned disclosed preferred embodiment is not the restriction to category of the present invention.On the contrary, the above-mentioned explanation and the arrangement of various change and isotropism are all the category that the present invention desires to be protected.Therefore, the category of the claim that the present invention applied for should be done the broadest explanation according to above-mentioned explanation, and contains the change that institute might equalization and the arrangement of tool isotropism.
