摘要： Contemplated magnetic buzzers include an elliptical or oblong resonator and magnet that significantly improve sound pressure level and audio quality. Most preferably, the resonator and magnet are disposed in a housing that comprises tab insertion channels that are fluidly coupled to solder channels, and tabs are coupled to and disposed within correspondingly shaped recesses in the housing to facilitate SMT mounting and to improve electrical contact stability.
