Abstract
A speaker includes a vibrating unit, a gasket and a magnetic circuit unit. The vibrating unit includes a diaphragm, and a voice coil electrically connecting to the elastic plate. The gasket supporting the position portion of the diaphragm includes a number of slots serving as air leaking holes for communicating interior of the speaker with exterior space. The combination of the diaphragm and the gasket is mounted to and positioned by the magnetic circuit unit. A projection of the diaphragm on the magnetic circuit unit is disposed within an outline of the magnetic circuit unit. The speaker has no frame or any structure with a frame configuration, which makes the magnetic circuit unit larger and more powerful.
