Abstract

The utility model relates to an improved mould of suspension sides body of a loudspeaker. A male mould of the utilize is provided with a vacuum generation controller and a vent hole, a female mould is provided with an airway, and rubber mixing materials are placed in a mould cavity; a finished product of suspension sides is formed in a foaming way by the vacuum inlet control of the vacuum generation controller. The suspending sides has medium specific gravity, the power of a sound basin is enlarged, the sensitivity is improved, the distortion rate is decreased, and the service life is long.

Description

The mould of suspension edge of loudspeaker body

The mould of the suspension edge of loudspeaker body of the relevant a kind of improvement of the utility model.

Press, the outstanding limit of the loud speaker of traditional type (loudspeaker) body has two kinds of constituted modes, and one is full solid rubber formula, and another is the continuous formula of full bubble.Now be described as follows with regard to two kinds of existing pluses and minuses of traditional type suspension edge of loudspeaker body: one, full solid rubber formula: (please in conjunction with consulting Fig. 1)

System selects solid rubber sheet 10 for use, be semi-finished product A with the mould die mould again, and the just general simple casted die mould of its mould, there is no special structure design, cooperate a die cutting die at last again, to hang that limit body 11, central waste material 12, leftover bits and pieces of material 13 separates and finished product B, outstanding limit body 11 finished products of its gained are that inside and outside to be all solid C airtight.This full solid rubber formula has the advantage of the muddy matter of tonequality (muddy heavy) and durable (rubber is more not perishable), but has following shortcoming:

1. be appreciated that the ratio great (about 1.2～1.4) of rubber, its sensitivity is less, thereby produces bigger distortion rate.

2. the traction force of rubber is bigger, thereby the performance (power output reduction) of restriction sound basin power output.

3. because of traction force is bigger,, thereby increase volume and weight so under the situation of equal-wattage output, the magnet of its use is inevitable bigger.

4. centre waste material 12 among cutting, its area is big, also is a kind of waste of material.

5. only be suitable for simple and honest tonequality, and inapplicable gently crisp, deep and remote gentle tonequality.

Two, steep continuous formula entirely: (please in conjunction with consulting Fig. 2)

System selects the continuous plate 20 of bubble that foams and finish for use, be suppressed into semi-finished product A with mould again, its mould also is general simple mould, there is no the special tectonic design, also cooperate a die cutting die at last again, to hang that limit body 21, central waste material 22, leftover bits and pieces of material 23 separates and finished product B, outstanding limit body 21 finished products of its gained are that the inside and outside pore D that is all is ventilative.This full bubble silk floss has gently crisp, the deep and remote soft advantage of bringing into play big power output of tonequality, but has following shortcoming:

1. be appreciated that the continuous material of bubble of pore, proportion is little, but too small, causes the tonequality can't simple and honest (muddy heavy).

Though 2. can bring into play bigger power, little because of proportion, pulling force is little, during excessive volume, will very easily cause distortion.

3. it has pore, and is ventilative, thereby when the sound basin stretches the start work done, disappointing problem must be arranged, and this also is the factor that causes easy distortion.

4. steep continuous material, be subject to weathering, corrosion, and perishable damage, useful life is shorter.

5. centre waste material 22 among cutting, area is bigger, also is a kind of waste of material.

6. be not suitable for the loud speaker of stressing simple and honest tonequality.

Therefore, the purpose of this utility model is to provide a kind of mould of producing the suspension edge of loudspeaker body of improvement, this mould may command vacuum, goes into gas, and thereby can produce frothing function, make its outstanding limit body finished product have the advantage of full rubber material and foaming structure, and do not have the shortcoming of the two.

According to the suspension edge of loudspeaker mould of the utility model, it is a male and female mould mould, and this male model is provided with air vent hole, and air vent hole is connected with vacuum generation controller, and this vacuum generation controller can make and form vacuum effectiveness in the die cavity; This master mold is provided with the ring-type airway, and airway is communicated in the male model air vent hole; Produce controller by air vent hole, airway, vacuum, can make the suspension edge of loudspeaker body of making, the shiny surface that produces surface is airtight, internal layer is for being full of the foaming layer of pore, reaches and hangs moderate, the air tight effect of limit body proportion.

Explain detailedly below in conjunction with structure, effect and the feature of accompanying drawing with regard to the utility model.In the accompanying drawing:

Fig. 1 is the outstanding limit of the traditional type body schematic diagram of full solid rubber;

Fig. 2 is the outstanding limit of the traditional type body schematic diagram of full bubble silk floss;

Fig. 3 is the utility model mould three-dimensional exploded view;

Fig. 4 is the utility model die assembly outside drawing;

Fig. 5 is the utility model mold actions figure;

The finished product schematic diagram that Fig. 6 makes for the utility model mould.

See also Fig. 3,4,5,6, the utility model is one to comprise the mould of male and

female mould

40,50, this male model 40 high energy air vent holes 41, and air vent hole 41 is connected with vacuum and produces controller 42, and this vacuum produces controller 42 and can make and form vacuum effectiveness in the die cavity 52; This master mold 50 is provided with ring-type airway 51, and airway 51 is communicated in male model 40 air vent holes 41; Insert the suitable rubber mixture of putting 31 (sulfur-bearing bridging agent) in its die cavity 52, being foamed forms outstanding limit body 30 finished products; Should hang limit body 30, surface engagement die cavity shiny surface, and be gas impermeable solid surfaces F, its inside is then for being covered with the foaming layer G of pore.

The process of utilizing the mould of the utility model to make finished product can be described in more detail as follows: (please again in conjunction with consulting Fig. 6) its mould produces controller 42 but the air vent hole 41, air vent hole 51, two air vent holes that are provided with air inlet, exhaust are connected with vacuum; When inserting suitable rubber mixture 31 (being mixed with the sulphur bridging agent) in die cavity 52 in order to do after heating, making the rubber mass foaming; Cover mould, make the mould vacuum produce controller 42 actions, via airway 51, air vent hole 41 and air-breathing.And give slightly and heating, make die cavity 52 be vacuum, and make rubber mixture 31 produce catalytic effect.To an appropriate time, mould is slightly promoted, produce slot, introduce air, the rubber mixture 31 of this catalysis can foam according to setting moment, and cooperates the shiny surface of die cavity face, the solid surfaces that rubber still can be possessed in its foaming surface, and airtight, but inside then is the pore that foaming is arranged.Remove burr E at last again, get product.

The mould of the utility model can be made has full solid rubber formula and the outstanding limit of the continuous formula of full bubble body Advantage and do not have the outstanding limit body of the two shortcoming do not see relevant prior art, and has enhancement Effect and practical value really meet the pertinent regulations of Patent Law, so it is special to propose utility model in accordance with the law Sharp application, request is ratified early.
