Abstract
A speaker assembly (100) includes a speaker (202) having at least one speaker terminal (206) and a magnet (204) which generates a magnetic field. The speaker assembly (100) also includes a circuit board (116) having at least one terminal (110). A metal member (106) is coupled to the circuit board (116) and is used to magnetically attach speaker (202) to circuit board (116). Upon speaker (202) being magnetically coupled to circuit board (116), the at least one speaker contact (206) becomes coupled to speaker terminal (110). Thereby, allowing for a quick way of attaching and detaching speaker (202) to and from circuit board (116).
