Description

Sound effect control device with halo effect and halo generation method thereof

The invention relates to a sound effect control structure; in particular to a sound effect control device having a halo effect and a halo generating method thereof.

There are many types of electronic products with sound and light effects on the market. How to stand out in the competitive market and win the favor of consumers is an important issue for manufacturers of related products. Although the cool effect of electronic products can attract the attention of consumers, but the consumer's willingness to purchase is still the price of the product. Therefore, if we can achieve the sound and light effect of the product itself, and reduce the production cost to reduce the price of the product, it is believed that the electronic product can be more competitive.

It is known that electronic products are light-emitting performances, which are light-emitting diodes (ie, LED lamps) that are easy to use, power-saving, popular, and inexpensive, and many LED lamps are often used to enhance the light-emitting effect. However, in terms of cost and power saving considerations, an excessive number of LED lights not only consume space, consume energy, but also are the most economical use options. Therefore, most electronic products have been modified to reduce the number of LED lamps used in conjunction with the configuration of the reflective surface.

However, the fabrication of the aforementioned reflective surface structure is often one of the reasons for the increase in cost. For example, in a device applied to sound (volume) control, in order to effectively reflect the bright light generated by the LED lamp, the reflective surface structure is formed by electroplating a reflective metal on one of the casings of the device. Layer or spray reflective paint to achieve. However, the processing method of the foregoing electroplating or spray reflective paint has a complicated process and avoids unnecessary waste of the reflective material and does not affect it. Under the appearance, it is necessary to carry out the processing of electroplating or spray reflective paint after the shadowing is not required, which increases the labor cost and the defective rate.

In addition, the reflective surface structure is directly cut from sheet metal. However, the reflective surface structure made of sheet metal is required to prepare a special cutting die or forming die depending on different products. After the metal sheet is fixed to the casing, the assembly is completed. However, the cutting die or the forming die is specially made to make the metal sheet after the cutting and forming have no intercommunication, and the metal plate is easy to increase the weight of the product, and the selling price thereof is one of the reasons for the increase in cost.
