Description

  The present invention mainly covers the front part of the speaker of a flat-screen TV speaker, a personal computer speaker, a mobile phone speaker, other acoustic products, home appliances, etc. The present invention relates to a method for manufacturing a speaker net that is blindfolded and configured to exhibit a dustproof function and the like, and in particular, its manufacturing can be easily performed, and the durability of the manufactured speaker net is improved. The present invention relates to a method of manufacturing a speaker net that has less obstruction of sound passage.

Conventionally, as a method for manufacturing this kind of speaker net, for example, means as shown in the prior art of Patent Document 1 has been adopted.
This is mainly made of a resin plate having punched holes or a polyester film having punched holes, and a polyester bag is bonded to these punched products. Moreover, when these are pasted together, a means is adopted in which a heat-sensitive adhesive such as hot melt is applied to the polyester basket and this is heated (for example, about 120 degrees) and pasted onto the punched product. Yes.

JP 7-42077 A

  However, in the conventional speaker net manufacturing means as described above, the adhesive adheres too much to the polyester bag, lowering the original opening ratio of the speaker net (opening ratio of the punching hole), and improving the performance of the speaker. There was a difficulty that could not be fully demonstrated. In addition, when the adhesion rate of the adhesive to the polyester ridge is reduced, the adhesive state between the punched product and the polyester ridge is reduced, and there is a difficulty in that it is easily peeled off. Moreover, since adhesiveness remains in the adhesive, there is a possibility that dust or the like is likely to adhere and the aperture ratio is further reduced.

  Accordingly, the present invention was created to solve the above-described difficulties and the like, and in the method for manufacturing a speaker net according to claim 1, a large number of small circular shapes are appropriately formed on the resin sheet material. A punching sheet 1 having holes 1a is formed, an adhesive layer 2 is formed on the back surface of the punching sheet 1, and a lining having a substantially lattice-like mesh size smaller than the diameter of the small holes 1a. A means for adhering the net 3 so that the back surface of the adhesive layer 2 was polymerized was adopted.

  Further, in the method for manufacturing a speaker net according to claim 2, a punching sheet 1 is formed by appropriately punching a large number of small circular holes 1a in a resin sheet material in a staggered manner. A pressure-sensitive adhesive layer 2 is formed on the back surface of 1, and a lining net 3 having a substantially lattice-like mesh size smaller than the diameter of the small hole 1 a is overlapped on the back surface of the adhesive layer 2. At the same time, a means for applying pressure to bond the punching sheet 1 and the lining net 3 was adopted.

  Therefore, according to the method for manufacturing the speaker net of the first aspect, the punching sheet 1 and the lining net 3 can be reliably and easily bonded through the adhesive layer 2 easily and efficiently.

  In particular, since the adhesive layer 2 is formed on the back surface of the punching sheet 1 and the lining net 3 is bonded so that the back surface of the adhesive layer 2 is polymerized on the side, the adhesive layer 2 is excessively formed on the back surface of the punching sheet 1. It is not provided, and the substantially lattice-like mesh of the lining net 3 is not narrowed by the adhesive layer 2, and there is no possibility of lowering the original aperture ratio of the speaker net. Moreover, the punching sheet 1 and the lining net 3 can be firmly bonded.

  In addition, since the lining net 3 formed with a substantially lattice-like mesh size smaller than the diameter of the small hole 1a is adhered, a part of the mesh portion of the lining net 3 always appears in each small hole 1a. As a result, a speaker net with excellent dust resistance can be provided.

  In addition, according to the method for manufacturing a speaker net according to claim 2, the punching sheet 1 and the lining net 3 can be reliably and easily bonded through the adhesive layer 2 in a simple and efficient manner.

In particular, a pressure-sensitive adhesive layer 2 is formed on the back surface of a punching sheet 1 formed by punching a large number of circular small holes 1a in a substantially staggered pattern, and the size of the substantially lattice-like mesh is the small holes 1a. The lining net 3 formed smaller than the diameter of the adhesive layer 2 overlaps the back of the adhesive layer 2 and pressurizes this to bond the punching sheet 1 and the lining net 3, so that the adhesive layer 2 becomes the punching sheet 1. It is not provided excessively on the back surface, and the substantially lattice-like mesh of the lining net 3 is not narrowed by the adhesive layer 2, and there is no possibility of lowering the original aperture ratio of the speaker net. In addition, the punching sheet 1 and the lining net 3 can be firmly bonded, the adhesive does not remain sticky, and there is no risk of dust or the like being attached, and a predetermined aperture ratio can be maintained.
Furthermore, a well-balanced opening can be easily provided in the speaker net.

  In addition, since the lining net 3 formed with a substantially lattice-like mesh size smaller than the diameter of the small hole 1a is adhered, a part of the mesh portion of the lining net 3 always appears in each small hole 1a. As a result, a speaker net with excellent dust resistance can be provided.

Hereinafter, the present invention will be described based on illustrated examples as follows.
The present invention protects the speaker itself, for example, by covering the front part of the speaker of a flat-screen TV speaker, a personal computer speaker, a mobile phone speaker, other acoustic products, home appliances, etc. This is a method in which a speaker net can be manufactured which is blindfolded and further capable of exhibiting a dustproof function and the like.
In this speaker net manufacturing method, first, a punching sheet 1 is formed by appropriately drilling a large number of small circular holes 1a in a resin sheet material. Next, the adhesive layer 2 is formed on the back surface of the punching sheet 1. Then, the lining net 3 formed so that the size of the substantially lattice-like mesh is smaller than the diameter of the small hole 1a is bonded to the back surface of the adhesive layer 2 so as to be polymerized.
