This invention includes a speakerphone accessory suitable for connection to either a battery charger having a phone in its pocket or to a cellular telephone. The speakerphone module includes a hemispherical upper housing. The upper housing includes a circular dimple aperture and a wave directing cap. The hemispherical shape, aperture and cap all contribute to directing acoustic waved generated by a speaker disposed within the housing radially from the module in all directions. One embodiment of the module includes a second terminal for passing data and power through the module, allowing the module to be coupled serially between devices. The module also includes a bottom housing having a generally hemispherical shape. The bottom housing provides stability to the connection between the module and a peripheral device in that it reduces the mechanical advantage given to forces incident upon the upper housing acting upon the main terminal.

A cigarette lighter adaptor for a portable electronic device is provided. The adaptor includes a handle and dongle coupled together by way of a mechanical stepper joint. The stepper joint includes a hinge that engages to resist angular forces applied to the handle relative to the dongle. In one preferred embodiment, the stepper joint includes a convex member with protruding members that act as gear teeth. The stepper joint has a corresponding concave member with d&eacute;tentes. When assembled, these features create the d&eacute;tente positions for the stepper joint. The d&eacute;tente positions are accomplished by allowing the dongle to translate along the axis of the adaptor away from the handle. The stepper joint is preferably held together with an elastic member wrapped about a pin within the stepper joint.

This invention includes a compliant removable battery support for configuring a pocket to accommodate devices of varying size. In one preferred embodiment, a charger is provided having a pocket capable of receiving an electronic apparatus, like a cellular phone for instance. The electronic apparatus is capable of having different sized batteries attached. The pocket size is adjusted by inserting the compliant removable battery support into a guide slot that corresponds to the desired battery size. In a preferred embodiment, the compliant removable battery support has a compliant member that comprises a four bar compliance mechanism. The four bar compliant mechanism provides more robust coupling between the compliant removable battery support and the charger in that the deflection stress is distributed across the compliant mechanism.
