Abstract
Abstract A radiotelephone device includes a case including a transceiver. A multilayer strap is attached to the case for fastening the device to a user's wrist. The multilayer strap has a top layer and a bottom layer. A microphone is electrically connected to the transceiver. A speaker is located at an end of the top layer of the strap and electrically connected to the transceiver. The speaker is located in a housing having a first surface substantially parallel to the top layer of the strap, and at least one other surface integrally connected to the first surface which is positioned at an angle with respect to the first surface. At least one sound port is located within the at least one other surface of the housing.
