Description
Technical field
The embodiment of the present invention is related to the processing unit (plant) and processing method more particularly to a kind of electroacoustic class intelligence of a kind of speaker net
The processing unit (plant) and processing method of the speaker net of energy hardware.
Background technology
During processing the speaker net of speaker, need to process on the component (such as plank) for forming speaker net more
A sound penetrating hole.Usually, the processing method of traditional speaker net has following manner：
(1) realize that Fig. 1 shows the sound penetrating hole arrangement mode processed in this way using etching punch pattern.
As shown in Figure 1, the arrangement of sound penetrating hole can be made more freely (as formed certain radian) in this way, and still, this side
Case corrosion is of high cost, and corrosion trepanning causes product strength poor and surface gets rusty easily, and is in addition required to plate thickness, if
Plank is too thick, it may be difficult to use.
(2) using large volume of raw material (being typically aluminium ingot either other metals) using section bar extrusion or numerical control
The method of machine tooling (CNC), first molds the appearance profile of product, and the method for then reusing CNC processes each entrant sound
Hole.In order to retain the acoustically transparent web frame of thin-walled, this method needs the input of a large amount of raw material, and time-consuming non-using process processing
Often long CNC largely cuts off feed stock material material, while processing big order of magnitude sound penetrating hole using CNC, leads to the urgency of cost
Play rises, and usually only the cost of speaker net will be more than the cost of the entire product of tradition.
In addition, there is also some other processing methods in the prior art, still, the sound penetrating hole of the speaker net processed
For arrangement mode as shown in Fig. 2, it can only process the sound penetrating hole of regular array, trepanning design freedom is low, has been unable to meet skill
Art demand.

A direction paying attention to, but in order to reach the perfectly balanced of euphony, hardware product performance and appearance, be directed to electroacoustic
The optimization design of the speaker net (especially its sound penetrating hole arrangement mode) of class product becomes what technological development personnel increasingly paid attention to
One emphasis.
However, for traditional diamond-making technique, it is difficult to take into account acoustic efficiency (corresponding to trepanning design freedom), hardware
Balance between appearance and cost or be exactly that acoustic efficiency is good, cost is good, but appearance is difficult to receive or is exactly acoustics effect
Fruit is good, and appearance is good, but cost is difficult to receive.The balance between this three how is effectively taken into account, is spoken with lower cost
It is good to learn effect, while the speaker net of hardware good appearance is that there is a continuing need for solve the problems, such as by the technological development personnel of electro-acoustic product.
