Abstract
This application provides a transducer including: a bracket, a voice coil, and a connecting terminal. The bracket has a first hole located in the center area and a notch located in the edge area. The voice coil includes a body, two tinsel wires extend from the periphery of the body of the voice coil, and at least a part of the body of the voice coil is located in the first hole of the bracket. The connecting terminal has two first conductive pads. The two tinsel wires are respectively connected to the two first conductive pads. At least a part of the connecting terminal is located in the notch.
Claims19
A transducer comprising:
- a bracket comprising a first hole located in a central area and a notch at an edge area and two support pieces located on both sides of the notch;
- a voice coil comprising a body and two tinsel wires extending from the body, wherein at least a part of the body is located within the first hole;
- a connecting terminal comprising two first conducting pads, and the two tinsel wires disposed on and connected to the two first conducting pads respectively;
- and
- a damper,
- wherein the connecting terminal includes a board having two opposite sides, namely a first side and a second side, the board is located on the two support pieces and in the notch, and the two support pieces expose at least a portion of a bottom surface of the board, and the first side is fully exposed by the notch, and the first side is aligned with an outer surface of a cylindrical wall of the edge area to form a continuous surface, and the bracket comprises a steady disposed below the edge area and between the first hole and the edge area, at least a part of the damper is placed on the steady, and the two tinsel wires of the voice coil are located above the damper.
A manufacturing method of a transducer, wherein the transducer comprises a bracket, a voice coil, a damper and a connecting terminal including a board having two opposite sides, the two opposite sides including a first side and a second side, the bracket has a first hole located in a center area and a notch located in an edge area, and two support pieces located on both sides of the notch, the voice coil has a body and two tinsel wires extending from the periphery of the body of the voice coil, and the connecting terminal has two first conductive pads;
- the manufacturing method comprising:
- electrically connecting the two tinsel wires to the two first conductive pads respectively;
- and
- vertically assembling the voice coil and the connecting terminal to the bracket;
- wherein at least a part of the body is located within the first hole and at least a part of the board of the connecting terminal is located on the support pieces in the notch, and the two support pieces expose at least a portion of a bottom surface of the board, and the bracket comprises a steady disposed below the edge area and between the first hole and the edge area;
- and the step of vertically assembling the voice coil and the connecting terminal to the bracket comprising:
- vertically placing the damper onto the steady;
- vertically disposing the two tinsel wires above of the damper;
- and vertically placing the board into the notch wherein the first side of the board is fully exposed by the notch, and the first side is aligned with an outer surface of a cylindrical wall of the edge area to form a continuous surface.
