    Abstract: A speaker includes a yoke, a diaphragm, an electrode plate, a magnet and a lower plate. The yoke includes a base, a wall and a terminal plate connected integrally to each other. The wall has a chamber and is mounted on the base. The rest components are mounted in the chamber. An amount of the components of the speaker is reduced because of the integral connection among the base and the wall. Consequently, the manufacturing costs and assembly process will be lowered and simplified.

    Abstract: A speaker includes a body, a yoke, and two connectors. The body includes an outer periphery with a recessed section. The yoke is securely mounted around the body and engaged with the recessed section. Each connector includes a first end fixed to the yoke and a second end. Each connector is at a level not beyond an end face of the body when the speaker is in an assembled state. Thus, the speaker has a reduced height, which is particularly useful for electronic devices that have a trend in miniaturization.
