Abstract: A frame of a bracelet-type electronic apparatus includes a plurality of main frame bodies, at least one elastic member and at least one first stopping member. The main frame bodies are arranged to form an arc-shaped structure, and two main frame bodies adjacent to each other define an interval. The arc-shaped structure defines a wearing space. Each of the main frame bodies has an inner side, exposed in the wearing space. The elastic member is connected to two adjacent main frame bodies. The elastic member is disposed on the inner sides of the main frame bodies. The first stopping member is protruded from one main frame body toward another main frame body adjacent to each other.

Abstract: A manufacturing method of an electronic device includes the following steps. A circuit board and at least one electronic component are provided, wherein the electronic component is installed on the circuit board. A protector is formed on the circuit board to cover the electronic component on the circuit board. A housing is formed by insert injection molding to cover the circuit board and the protector.

Abstract: An angle adjustment mechanism including a first body, a second body and a restoring element is provided. The first body has a first positioning structure. The second body is movably coupled to the first body and has a second positioning structure engaging to the first positioning structure, and the second body is adapted to rotate relative to the first body about an axial direction, so that the second positioning structure moves away from the first positioning structure along a radius direction. The restoring element is coupled to the second body and adapted to accumulate a restoring force when the second positioning structure moves away from the first positioning structure. The second positioning structure is adapted to approach the first positioning structure along the radius direction via the restoring force after the second body rotates an angle relative to the first body, so as to reengage to each other.
