Abstract
Some embodiments of the present invention enable a user to select from different appearances and sound types by providing different door chime assembly housing covers. The housing covers can be different in shape, size, appearance, and/or acoustic property, and preferably can be releasably mounted a housing base. A door chime assembler, manufacturer, or user can therefore select from different door chime assembly appearances and acoustic properties by selecting one of two or more different housing covers. The door chime assembly can employ a number of different features that change the sound quality of the door chime assembly, including a domed or tented housing cover shape, a housing cover having curved edges and corners, an open acoustic chamber unbroken by internal walls, and side wall housing apertures. Other significant advantages are provided by the use of a door chime assembly transformer that is mounted to the door chime assembly housing.
