A frame with an outer silicon layer and a manufacturing method of forming the silicone layer on the outer part of frame are disclosed. The manufacturing method includes a forming step, a combining step and a removing step. First, a pair of mold with a forming space is formed with a silicone carrier including an effective combination region and an ineffective region. An emplacing space is next formed in the effective combination region and a frame is put into the emplacing space. Before putting in the frame, either the outer part of frame or the emplacing space is coated with a silicone coating, and then the effective combination region is combined on the outer part of frame by a secondary sulfurization. Finally, the effective combination region is removed from the ineffective region to form a silicone layer, made of the effective combination region, on the outer part of frame.

An injection molding method for a semifinished product includes a semifinished product emplacement step, a semifinished product pre-compression step and a forming step. First, a pair of mold with a forming space is provided. A semifinished product is put into the mold, and a first joint is performed to the mold by a press-fit jig, fixing the semifinished product in the forming space. The semifinished product is also tightly fitted with the mold. Next, a first open-die is performed and the press-fit jig is removed. After that, a second joint is performed, and a forming material is injected into the forming space. Finally, a second open-die is performed, and then a finished product is formed. By the semifinished product pre-compression step, the forming material can be prevented from resulting in spill or burr on the semifinished product, thereby improving the yield of injection molding.

A lens structure formed by materials in different refractive indexes includes a transparent sphere in a first refractive index as well as a transparent second lens in a second refractive index. The first refractive index is different from the second refractive index, and the sphere is a round ball formed by a first portion and a second portion which are equipped with a first light condensing effect. The first lens is formed on the first portion of the sphere, the second portion of the sphere is exposed out of the first lens, and the first lens is provided with a first light absorption curve opposite to the first portion of the sphere, so that a light beam can pass through the second portion of the sphere to form the first light condensing effect, and then pass through the first light absorption curve to form a second light condensing effect.

A lens structure formed by materials in different refractive indexes includes a sphere, a first lens and a separation layer which is disposed between the sphere and the first lens. The sphere and the first lens have a different refractive index and the sphere is a round ball. The first lens is formed on the sphere that part of the sphere is exposed out of the first lens, and the first lens includes a first light absorption curve. The separation layer includes a transparent section opposite to the first light absorption curve. When a light beam passes through the second portion of the sphere to form a first light condensing effect and enter the sphere, the light beam will then pass through the transparent section to enter the first lens, forming a second light condensing effect after passing through the first light absorption curve.

A direction-adjustable jig is capable of translating an artifact between two mutually perpendicular planes in a three-dimensional space. The jig includes a base, a sliding member, and a hinge member. The base has a pair of side walls each having a first guiding portion. The first guiding portion has a lower guiding portion and an upper guiding portion in communication with each other. The lower guiding portion and the upper guiding portion are formed at different height vertically. The sliding member is disposed reciprocatingly on the base and in between the side walls. The hinge member is pivotally connected to the sliding member and has a pair of second guiding portions for engaging the first guiding portions. The reciprocating motion of the sliding member allows the hinge member to rotate above the base and change its direction.

The instant disclosure relates to a manufacturing method of a sound playing assembly for micro-sized speaker. The method includes the following steps: providing a carrier having a strip-shaped grill member; cutting the carrier after it has been transferred into a cutting unit to obtain a trimmed grill member; transferring the trimmed grill member onto a machine plate; and performing injection molding with molten plastic after the trimmed grill member is transferred from the machine plate into a mold by a material handling equipment, in order to form a seat body having a speaker basket surrounding the trimmed grill member, with the speaker basket partially embedded in the grid structure of the trimmed grill member. The trimmed grill member and the seat body are thus formed integrally in providing a sound playing assembly. The assembly can help to improve production yield rate and be mass-produced in an automated process.
