Embodiment Construction

[0014] see Figure 1 to Figure 2 , the loudspeaker sounding board of this embodiment is a composite double-layer board, which is composed of a surface layer 1 and an adhesion layer 2. The surface layer 1 and the adhesion layer 2 are bonded together by glue, and the surface layer 1 is a grating layer. This embodiment adopts a lenticular lens grating , the number of grating lines of the grating layer is 70-100 lines, and the adhesion layer 2 is a cardboard layer, and coated paper is used in this embodiment. In this embodiment, the thickness of the sounding plate is 0.8mm-1.8mm, and the thickness of the grating layer is 0.45-0.9mm.

[0015] see image 3 , the present invention forms a composite material through the bonding of the grating material and the cardboard, utilizes the characteristics of light weight and good rigidity of the cardboard, and the combination of the grating material increases the weight of the entire composite material as a whole and increases the sound qua...

Abstract

The invention discloses a sound production plate for a loudspeaker, and aims to solve the problems of poor low frequency effects of the existing sound production plate. The sound production plate for the loudspeaker is a composite double-layer plate, and consists of a surface layer and an adhesive layer, which are adhered together, wherein the surface layer is a grating layer; and the adhesive layer is a paperboard layer. A grating material is adhered together with a paperboard with the characteristics of light weight and high rigidity to form a composite material, so that the weight of the whole composite material is increased, and the low frequency effects of sound are improved; and prisms are uniformly arranged at intervals in the grating layer, so that the resonance of the sound is eliminated when the whole sound production plate irregularly rotates to produce the sound after a driver works, the composite sound production plate can produce sound more clearly, and gooseflesh caused by the irregular vibration is eliminated.

Description

technical field [0001] The invention belongs to the field of audio, and in particular relates to a loudspeaker sounding board. Background technique [0002] The sounding board of the existing flat-panel speakers generally adopts honeycomb structure materials, and the materials generally used are lighter materials such as aluminum alloy composite boards and paper honeycomb boards; the honeycomb structure has the advantages of heavy load, light weight, and good rigidity. And other characteristics, when in use, it has the advantages of high treble and clear sound. But the disadvantages are also obvious. If the low frequency cannot come down, generally it can only be at 160Hz or above, and the restrictions on use will be obvious. Contents of the invention [0003] The object of the present invention is to solve the above-mentioned problems existing in the existing sounding boards, and provide a loudspeaker sounding board which can improve the low-frequency effect of the sound...
