A kind of dustproof, shielding speaker net

Technical field

The utility model relates to a kind of dustproof, shielding speaker net.

Background technology

Along with the raising of people's living standard, traditional white domestic appliances market is saturated gradually, and the market demand of audiovisual entertainment equipment is significantly increasing, for example high end audio, have amusement function TV, Mike, power amplifier etc.In the design and R﹠D process of audiovisual entertainment equipment, engineer or research staff need consider problems such as the inner associated hot design of product, electromagnetic interference control usually, in addition because the power consumption of amusement equipment is bigger, the emission control design of heat is very important, if this partial design is improper, then may causes the equipment local overheating and cause fault or cause disaster.Satisfying under the good situation of heat radiation, also must consider problems such as its ELECTROMAGNETIC OBSCURANT, static electricity prevention and curing, if this partial design is not good, then may cause equipment under the situation under long-time the use within it portion accumulated a large amount of electrostatic charges, and then may cause local electronic device failure or damage.Must consider also that as designer or research and development engineer equipment can't be subjected to the interference of outside strong electromagnetic wave, for example under Lei Ji the situation, outside strong sound wave or strong electromagnetic wave disturb the situation of stereo set.Traditional method adopts the Merlon net and the conduction grenadine of common speaker net, conducting layer coated mostly.Common speaker net can satisfy the requirement of equipment to dustproof and ventilation and heat substantially, but a large amount of electrostatic charges of its inner accumulation easily under long-time situation about using, and then cause local electronic device failure or damage, cause to occur phenomenons such as noise or local function inefficacy when playing; The Merlon net of conducting layer coated, it is Merlon net coating conductive paint, have preferably dustproof and result of ventilating heat dissipation and certain static release function, but conductive paint move under hot environment for a long time and come off easily, the collision in the use also easily causes its corresponding function inefficacy; The conductive mesh yarn material is that grenadine cloth forms through plated metal, have preferably functions such as dustproof, ventilation and heat and static release, but cost an arm and a leg, and the lear energy of conduction grenadine is relatively poor, generally be used on the mini-plants such as microphone, receiver, earphone, the application on large-scale amusement equipment is greatly limited.

Summary of the invention

The purpose of this utility model provide a kind ofly have that better dust control by ventilation, static are led away, electro-magnetic screen function and the dustproof, shielding speaker net of tear resistance preferably.

For achieving the above object, the technical solution adopted in the utility model is: a kind of dustproof, shielding speaker net, comprise the speaker net body, be arranged on a plurality of heat radiation perforation on the described speaker net body, described speaker net body comprises bonding insulating film layer and conduction layer of cloth, and described insulating film layer and conduction layer of cloth are all passed in each described heat radiation perforation.

Preferably, described conduction layer of cloth comprises fiber cloth, is plated on the metal conducting layer on the described fiber cloth, and described insulating film layer is arranged on the described metal conducting layer.

Further preferably, described conduction layer of cloth comprises also and is coated with the conductive coating that is located on the described metal conducting layer that described insulating film layer is bonded on the described conductive coating.

Still more preferably, described conductive coating is selected black conductive carbon black coating for use.

Preferably, described insulating film layer adopts polyester film.

Preferably, the adhesive that bonds between described insulating film layer and the conduction layer of cloth is resistant to elevated temperatures conduction acrylic glue or PUR.

Because the utilization of technique scheme; the utility model compared with prior art has following advantage: layer of cloth is bonding forms by insulating film layer and conduction for this dustproof, shielding speaker net; has lear energy preferably; with respect to the conduction grenadine; price is also relatively more cheap; can be widely used in the large-scale amusement equipment; this speaker net when mounted; the conduction layer of cloth is bonded at the horn mouth position of corresponding components and parts; insulating film layer is provided with outwardly; insulating film layer plays the insulation protection effect; the conduction layer of cloth can will be deposited in the lip-deep electrostatic charge of components and parts and lead away; prevent the infringement that static causes components and parts; the layer of cloth that conducts electricity simultaneously can also cover certain electromagnetic wave; make the sound information systems such as loudspeaker on the amusement equipment not be subjected to the interference of external electromagnetic ripple, this speaker net also plays dustproof effect, and carries out ventilation and heat by the perforation of the heat radiation on the speaker net.

Description of drawings

Accompanying drawing 1 is the partial schematic sectional view of dustproof, shielding speaker net of the present utility model;

Embodiment

Further set forth structure of the present utility model below in conjunction with accompanying drawing.

Referring to shown in Figure 1, a kind of dustproof, shielding speaker net, comprise the speaker net body, be arranged on a plurality of heat radiation perforation 1 on the speaker net body, the speaker net body comprises bonding insulating film layer 2 and conduction layer of cloth 3, and insulating film layer 2 and conduction layer of cloth 3 are all passed in each heat radiation perforation 1.Add man-hour, earlier insulating film layer 2 and conduction layer of cloth 3 are bonded together, re-use press equipment it is carried out pressing, guarantee that the two fits tightly together, insulating film layer 2 after utilizing punching apparatus to pressing then and conduction layer of cloth 3 carry out punching processing, form heat radiation perforation 1.This dustproof, shielding speaker net in use, the conduction layer of cloth 3 on the speaker net sticks on the horn mouth position of components and parts on the amusement equipment by electroconductive binder, insulating film layer 2 is provided with outwardly, the heat when a plurality of heat radiations perforation 1 can be with inner components and parts work is discharged.Insulating film layer 2 plays the insulation protection effect; conduction layer of cloth 3 can be led away being deposited in the lip-deep electrostatic charge of components and parts; prevent that static from causing damage to components and parts; the layer of cloth 3 that conducts electricity simultaneously can also cover certain electromagnetic wave, makes the sound information systems such as loudspeaker on the amusement equipment not be subjected to the interference of external electromagnetic ripple.This speaker net also plays dustproof effect.In addition, this speaker net is pasted by insulating film layer 2 and conduction layer of cloth 3 and is formed, and has lear energy preferably, with respect to the conduction grenadine price comparison cheap, can be widely used in the large-scale amusement equipment.
