Abstract

The invention relates to a curlable sound condensation film which is formed through the compounding of 1-2 layers of curlable films, wherein at least one layer is a reflection layer which can be directly made of hard material. A hard reflection film consisting of a metal film can be plated on the reflection layer. The reflection layer is provided with a plurality of circles of annular convex-concave stripes. The convex part of each convex-concave stripe is a concave surface. The focuses of all the concave surfaces of all the annular convex-concave stripes point to one point. The concave surface film formed in such way is equal to a concave reflection surface. Sound coming from far places hits the concave reflection surface in an approximately parallel manner. Due to the condensation capability of the concave reflection surface, the sound can be reflected to the focus.

Description

The poly-sound film that can curl

Affiliated technical field the present invention relates to a kind of film that sound is focused on, especially a kind of poly-sound film that can curl.

Background technology is present, mostly be to utilize parabolic device that sound is focused on, the sound that transmits utilizes paraboloidal focussing property near bumping against on the parabola abreast at a distance, and sound reflection is arrived the focus place, directly monitor or place sound transducer at the focus place at the focus place, handle amplification after utilizing sound transducer that sound is become electric signal, parabolic device volume is bigger, and is not portable, and it is higher to make huge parabolic cost, also very inconvenient.

Summary of the invention is in order to solve the at present poly-very much not portative drawback of acoustic device volume, the invention provides the poly-acoustic device of a kind of cost film lower and easy to carry, the poly-sound film that it utilizes multi-turn annular concave surface film formation to curl, this poly-sound film is simple and easy to realize.

The technical solution adopted for the present invention to solve the technical problems is: this poly-sound film is composited by the film that the 1-2 layer can curl, wherein have at least 1 layer to be the reflection horizon, the reflection horizon can directly be made with hard material, also can on the reflection horizon, plate the layer of metal film and constitute the hard reflectance coating, there is the reflectance coating of one deck hard on the surface in reflection horizon, the back side in reflection horizon also can compound layer protective layer, this protective seam is a thin film, it can improve the intensity of this poly-sound film, avoid rigid folding to hinder, protective seam can be the plane also can be other shape, if the anti-folding of the material in reflection horizon wound property is better, protective seam can not wanted, multi-turn ring-type convex-concave striped is arranged on the reflection horizon, the bossing of every convex-concave striped is a concave surface, the focus of the concave surface of all ring-type convex-concave stripeds is all pointed to a bit, the concave surface film of Zu Chenging is equivalent to a concave reflection face like this, compacting forms if ganoine thin film is directly used in the reflection horizon, the surface, reflection horizon just no longer needs to plate the hard reflectance coating, the sound that transmits is similar to and bumps against abreast on the concave reflection face at a distance, because the focussing property of concave reflection face, sound reflection is arrived the focus place, directly monitor at the focus place or accept with sound transducer, the reflection horizon of this poly-sound film can use materials such as polyethylene film or polyacrylic plastics film through mold pressing, method such as rotary-cut or engraving is made, also can be on the reflection horizon sputter or electroplate the layer of metal reflecting material again; Can also the reflect sound spy preferably on the film directly mold pressing, rotary-cut or Carving Machining make.

This poly-sound film that can curl; can be widely used in open-air animal monitors; the crisis rescue; multiple fields such as personnel's search and rescue and military monitoring; the color of this poly-sound film can be made camouflage color or other color; on runing rest, settle this poly-sound film, can to around 360 ° carry out omnibearing remote sound detection.

The invention has the beneficial effects as follows that this poly-sound film can curl, volume is little, and cost is low, can make large-scale poly-sound wall easily, and transportation and easy to carry, because the technical measures that this invention is taked all are mature and feasible, so can realize.
