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.

The instant disclosure relates to a direction-adjustable jig, which includes a base, a sliding member, and a hinge member. The base is topped with a platform having a pair of guide rails. The two guide rails extend in opposite directions and are parallel to each other. The sliding member is disposed on the platform and capable of reciprocating motion. The hinge member is disposed on the platform and pivotally connected to one end of the sliding member. The hinge member is rotatable above the base. The hinge member further has a pair of protruding guide teeth. The guide teeth are perpendicular to each other and insertable into the guide rails. Through the motion of the sliding member on the platform, the guide teeth of the hinge member can be inserted into respective guide rails, such that the hinge member can rotate above the base and change its direction.
