Abstract
The utility model discloses a speaker, which comprises a cone arranged with a plastic-foam layer. The cone can consist of a single layer with a plastic-foam layer adhering thereon or consist of two layers with the plastic-foam layer positioned therein. The plastic-foam layer is made of plastic material PU or PE. Compared with the prior art, the utility model has the advantages that due to the light weight and the high strength of the plastic-foam layer arranged on the speaker cone, the speaker cone of the utility model has higher strength than the conventional speaker cone, besides, has the advantages of light weight, wide frequency response range and low distortion.
Description
Technical field
The utility model relates to a kind of loud speaker, relates to the improvement technology of speaker cones specifically.
Background technology
At present, the shake Material Used and the production technology of basin of conventional loudspeakers mainly contains following several: 1, fiber such as paper pulp drags for the slurry moulding; 2, the light metal paper tinsel moulding of extending; 3, fibrous braid impregnation moulding; 4, honeycomb section bar bonding forming etc.Speaker cones is mainly used in the sound that promotes air and send different frequency, though above-mentioned 1,2,3 kind of material satisfies in light weight, highly sensitive requirement, all causes quality distortion because of rigidity is bad.Though the 4th kind of Material Used can improve rigidity. be difficult to satisfy requirement to different tonequality, and the cost height, complex process is difficult to apply.
Summary of the invention
The purpose of this utility model provides the loud speaker that a kind of intensity is good, in light weight, frequency response range is wide, distortion is little.
The utility model is achieved through the following technical solutions the object of the invention.
A kind of loud speaker comprises the basin that shakes, and it is characterized in that: the described basin that shakes is provided with the plastic foam layer.
The described basin that shakes is the individual layer basin that shakes, and the plastic foam layer shakes attached to individual layer on the basin.
The described basin that shakes is the bilayer basin that shakes, and the plastic foam layer is arranged in the bilayer basin that shakes.
Described plastic foam layer is made by plastic material PU or plastic material PE.
The utility model compared with prior art has the following advantages.
Because the plastic foam layer has characteristics in light weight, that intensity is good, the plastic foam layer is arranged on the speaker cones, the utility model speaker cones is increased with respect to traditional speaker cones intensity, have advantage in light weight, that frequency response range is wide, distortion is little simultaneously.
Description of drawings
Fig. 1 is arranged in the shake loud speaker of basin of bilayer for the utility model plastic foam layer;
Fig. 2 for the utility model plastic foam layer attached to shake loud speaker on the basin of individual layer.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
The shake Material Used of basin and production technology such as background technology of conventional loudspeakers described, cause quality distortion because of rigidity is bad or satisfy the rigidity requirement though they all exist, but be difficult to satisfy to the requirement of different tonequality and cost height, complex process, be difficult to apply.
First kind of embodiment of the utility model as shown in Figure 1, with the light material of foaming such as plastic foamed foam 1 such as PU or PE be filled in bilayer shake form in the basin 2 in the middle of froth bed.Second kind of embodiment of the utility model is attached to tradition with the light material of foaming such as plastic foamed foam 1 such as PU or PE and shakes and make the froth bed basin that shakes on the basin 2 as shown in Figure 2.That these two kinds of embodiments all have is in light weight, good rigidly, Hz-KHz is wide, distortion is little advantage, can realize the requirement of high-quality loud speaker to the basin that shakes fully.The basin that shakes of the explained hereafter that this structure adopted, bonding reliability height, high conformity, stay in grade, production cost are low.The density of foaming layer, intensity can be regulated arbitrarily, can make difformity as requested, the basin that shakes of different frequency scope, different loud speakers.
Claims (4)
