Problems solved by technology

However, the existing loudspeaker vibrating basin has a single color and the three-dimensional effect is not strong. Moreover, due to the sounding function of the vibrating basin, most of the shapes are trumpet-shaped, and it is difficult to make a breakthrough in the shape and structure. Can it be used in the current There are structural innovations and improvements, which are research topics for industry peers

Embodiment 1

[0019] In this embodiment, PP plastic is used as a raw material to prepare the vibration body base. First, use transparent material PP to form the vibrating body substrate according to the requirements; add PP treatment agent on the surface of the vibrating body substrate to facilitate the adhesion of the spray paint layer. The PP treatment agent can be commonly used in the market, such as DX-P-88 treatment agent. The treatment agent is widely used in various PP treatment, the main components are: polyolefin resin, petroleum resin, toluene, methyl ethyl ketone.

[0020] For the prepared vibrating body with a maximum diameter of 10 cm, the rotating speed of the spraying equipment is 84 rev / min, and the spray is sprayed from the center of the vibrating body substrate to the edge of the vibrating body substrate, and sprayed to the position of 4 / 5 from the edge of the vibrating body substrate Finally, start spraying from the edge of the vibrating body substrate instead, and spray ...

Embodiment 2

[0024] In this embodiment, the vibrating body base is prepared from paper materials. Since the vibrating body substrate made of paper material is opaque, the sprayed layer is provided on the front side of the vibrating body. The paper material has strong adhesion, and it is not necessary to coat additives that increase the adhesion of the pigment.

[0025] For the prepared vibrating body with a maximum diameter of 15 cm, the rotating speed of the spraying equipment is selected to be 86 rpm, and the spray is first sprayed from the center of the vibrating body substrate to the edge of the vibrating body substrate, and sprayed to a position 1 / 2 from the edge of the vibrating body substrate Finally, start spraying from the edge of the vibrating body substrate instead, and spray to all remaining positions. The spraying time from the center of the vibrating body base to the edge of the vibrating body base is 12 seconds, and the spraying time from the edge of the vibrating body base...

Embodiment 3

[0028] In this embodiment, a vibrating body base is prepared using metal materials as raw materials. Since the base body of the vibrating body made of metallic material is opaque, the sprayed layer is arranged on the front side of the vibrating body. The adhesion of metal materials is poor, and it is necessary to apply a treatment agent to increase the adhesion of pigments.

[0029] For the prepared vibrating body with a maximum diameter of 10 cm, the rotating speed of the spraying equipment is selected to be 80 rpm, and the spray is first sprayed from the center of the vibrating body substrate to the edge of the vibrating body substrate, and sprayed to a position 1 / 2 from the edge of the vibrating body substrate Finally, start spraying from the edge of the vibrating body substrate instead, and spray to all remaining positions. The spraying time from the center of the vibrating body base to the edge of the vibrating body base is 10 seconds, and the spraying time from the edge...

Abstract

The invention relates to the technical field of a loudspeaker flap basin. The loudspeaker flap basin comprises a flapping body on the middle part and a flap basin edge connected to the periphery of the flapping body, wherein a pigment layer which is a chromatic layer gradually changing from a dark colour to a light colour is formed on the flapping body. The preparation process comprises the following steps of: preparing a flapping body base body, adding a PP processing agent contributing to the adhesion of a sprayed pigment layer to the surface of the flapping body base body which is made from transparent plastic material PP, spraying from the centre of the flapping body to the edge of the flapping body with a spraying equipment, and after spraying to 1 / 2 to 4 / 5 the position from the edgeof the flapping body, spraying from the edge of the flapping body until all the remained part is sprayed. According to the structural features of the flapping body of a loudspeaker, the invention creatively provides a two-step spraying method, in which spraying is performed from the centre to the edge and then from the edge to the centre so as to generate the gradual chromatic effect on the pigment layer of the flapping body. The flap basin provided by the invention breaks through the feature of traditional single shape and has obvious economic and marketing value.

Description

technical field [0001] The invention relates to the technical field of a loudspeaker vibrating basin, in particular to the technical improvement of the loudspeaker vibrating basin and its manufacturing process. Background technique [0002] The loudspeaker cone is a component of the loudspeaker and is a very commonly used electroacoustic transducer. The loudspeaker cone is mainly used to push the air to emit sounds of different frequencies. The improvement of the existing loudspeaker cone mostly changes in the materials used and its shape to obtain better effects. [0003] The loudspeaker cone is mainly composed of a vibrating body in the middle and a vibrating basin edge connected to the periphery of the vibrating body. The function of the vibrating body is to receive air vibration and transmit the vibration. The function of the side of the vibrating basin is to connect the vibrating body fixedly, and the vibration of the vibrating body is buffered by the arched side of th...
