Abstract: An electronic device (100) includes an attached door cover (150) having a speaker (160) with an integral speaker magnet (165) that is used as an actuator for a magnetically enable switch (130) positioned within the housing (115) of the electronic device (100). The door cover (150) is movable between a first position adjacent to the housing (115), and a second position having at least a portion of the door cover (150) away from the housing (115) and the switch (130) is actuated magnetically by the speaker magnet (165) when the door cover (150) is in the first position. Preferably, the speaker magnet (165) helps to latch the door cover (150) closed. Additionally, the door cover (150) is preferably detachable from the housing (115) of the electronic device (100) and is user replaceable.

Abstract: A device used with a portable radio (10) and associated carrying case (30) which can automatically adjust radio control functions such as audio output, DTMF tone level mode telephone hang-up or illumination levels of the radio depending on the radio's position in relation to the carrying case. The radio (10) includes a hall effect switch (14) used to signal the a microprocessor within the radio when actuated. A magnet (38) located within the case (30) actuates the hall effect switch (14) when the radio (10) is placed within the case (30). The microprocessor is then signaled to change radio function aiding the user in the operation of the radio (10) depending on the its position.
