发明名称 Mail alert
摘要 A mail notification system for use with structures and residences is disclosed. The mail notification system comprises an activator attachment that is attached to an inner surface of a mailbox. The activator attachment includes an activator that is kept in a retracted position by a flange attached to a mailbox door when the mailbox door is shut. Once the mailbox door is opened, the activator opens to an extended position, thereby activating a radio wave transmitter in the activator attachment. The radio wave transmitter emits radio waves that are picked up by a radio wave receiver that is incorporated into a face plate unit that is preferably located within a residence of an individual. The radio wave receiver then activates a speaker to emit sounds and an attached display to display words that indicate the mailbox door has been opened, suggesting mail has been deposited in the mailbox.
