Speaker

摘要

A speaker of the present invention is used for converting audio electrical signals to audible sounds. The multi-magnetic circuit speaker includes a box with a sound hole, at least one magnetic circuit having at least two magnetic gaps, at least two vibrating units corresponding to the magnetic gaps, respectively, at least two pair of pads embedded in the box to electrically connecting with the two vibrating units, a terminal board engaged with the box and pressing on the two pads for conducting electrical signals to the two vibrating units. The terminal board includes a first portion, a second portion extending from the second portion and a third portion extending from the second portion.

主权项

1. A speaker comprising:
a box having a cavity with a sound hole and defining a cover, a case and a frame sandwiched between the cover and the case; a magnetic circuit unit received in the cavity and having a first magnetic gap and a second magnetic gap; a first vibrating unit defining a first diaphragm and a first voice coil suspended in the first magnetic gap; a second vibrating unit defining a second diaphragm and a second voice coil suspended in the second magnetic gap; a pair of first pads embedded in the cover for electrically connecting with the first voice coil; a pair of second pads embedded in the frame for electrically connecting with the second voice coil; a terminal board mounted on the outer surface of the box and defining a first portion mounted on the cover for electrically connecting with the pair of first pads, a second portion extending from the first portion and mounted on the frame for electrically connecting with the pair of second pads, a third portion extending from the second portion and mounted on the case for electrically connecting to an external circuit.
