## Background
FIELD OF THE INVENTION
The present invention relates to a device indicating that the door of a vehicle is opened and, more particularly, to such devices that are able to play a favorite song or music upon opening the door of a vehicle.
BACKGROUND OF THE INVENTION
Known from U.S. Pat. No. 4,839,749 issued on Jun. 13, 1989, to Eustace Franklin, is a vehicle safety and personal message system primarily designed to be incorporated into a vehicle to provide the driver with a pre-recorded speech message pertaining to either a vehicle safety alert or a personal message. The safety alerts include such events as: door ajar, burglar alarm ON or OFF, speed limit exceeded and a fire/police siren detector. The personalized messages include reminders such as birth dates, anniversaries, meeting date/time and scheduled maintenance periods. All the messages can be recorded in any language and in any local or ethnic jargon and the personal messages may be programmed to occur at anytime within a one-year period. Although the system's primary usage is for vehicles, it can also be adapted for use on many other products that utilize short messages.

Disclosed in a US patent application 2007/0001824 A1 published on Jan. 4, 2007, and authored by Donna Lee is a vehicle alarm system that can sound in any variety of tones, sounds, sequences, songs, melodies, tunes, and/or any other prerecorded or individually created and/or determined phrases, statements, songs, tunes, tones, etc.
Known from U.S. Pat. No. 6,130,605 issued on Oct. 10, 2000, to Kenneth E. Flick is a vehicle security system includes an audible alarm indicator, and a controller to generate an alarm indication comprising a plurality of distinguishable sound patterns. The sound patterns overlap in time yet are audibly distinguishable from one another to thereby create an illusion of multiple alarms. Accordingly, a would-be thief may be convinced that multiple vehicle alarms have been triggered and, thus, that more than one vehicle owner may be alerted. The vehicle security system may include at least one vehicle security sensor, and the controller is preferably responsive to the sensor to generate the audible alarm indication. The distinguishable sound patterns may be different from one another. In some other embodiments, at least two of the distinguishable sound patterns are the same sound patterns, but which are out of phase with one another to provide the illusion of multiple alarms. Each of the distinguishable sound patterns preferably includes successive repetitive portions. For example, each of the distinguishable sound patterns may include repetitive changes in at least one of frequency and volume.
Yet, a need exists for an indicator system that could play music or transmit a message upon opening a door of a vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Before starting a detailed description of the disclosure, mention of the following is in order. When appropriate, like reference numerals and characters may be used to designate identical, corresponding, or similar components in different figure drawings. The following description is merely exemplary in nature and is not intended to limit the described embodiment. As used herein, the word “exemplary” or “illustrative” means “serving as an example, instance, or illustration.” So the implementation described hereinafter as “exemplary” or “illustrative” is not necessarily to be construed as preferred or advantageous over other implementations. The implementation described below is an exemplary implementation provided to enable persons skilled in the art to practice the disclosure and is not intended to limit the scope of the claims. As used herein, relative terms such as “top,” “bottom,” “upper,” “lower” are used for descriptive purposes only and not in a limiting sense.
Referring now to the drawings of FIGS. 1-6, a door opening indicator system 10 for a vehicle 12 generally comprises a base unit 14 and a remote unit 16. Also components of the system are a computer 18 and door opening sensors 20.
Structurally, the base unit 14 makes a box 22. In an exemplary version, the box would be 1⁄2 inch tall, 3⁄4 inch long and 11⁄2 inches wide. Practically, the box 22 can be placed instead of a current device under the hood as shown in FIG. 4 or in the glove box. The box 22 is provided with a pair of spaced positive and negative terminals 24 shaped like straight posts for easy plug-in connection of the base unit 14 with a vehicle power system such as battery (not shown). Other structural elements of the box 22 shown in FIGS. 1-3 are speaker holes 26, a PC port 28, and a mounting element 30 with an eye 32. Proper wiring 34 would connect the base unit 14 with a vehicle control unit (on-board computer 36). The computer 18 of the system according to the present disclosure can include the on-board computer 36.
The base unit 14 comprises an input circuit 38 connected to a CPU 40, and a software carrier 42, memory 44, a speaker 46, and an interface circuit 48 all connected to the CPU 40. The remote unit 16 has means (not shown) for recording and reproducing music and/or voice messages and wirelessly transmitting them to the base unit 14. It is provided with buttons “On/Off” 50, “Record” 52, “Play” 54, and “Shuffle” 56, as well as microphone 58.
Preprogramming the base unit 14 from the remote unit 16 can be performed at any time in advance. Music or message transmitted to the base unit go through the input circuit 38 and CPU 40 and would be stored in the memory 44 When the system is in use, opening a door actuates the opening sensor 20 of that door, and the sensor communicates with the computer 18, which controls the base unit through the interface circuit 48. According to the software 42, the CPU 40 extracts the music or message from the memory and directs it to the speaker 46. Instead of hearing a conventional buzzer or dinging noise, the motorist could hear a favorite song or voice message.
It is believed that the system according to the preent disclosure would fulfill the need for an interesting voice message or music that would sound upon opening a vehicle door. The system provides a personalized and customized vehicle and does this in such an interesting manner that was sure to attract the attention of others. The product could be used with virtually any private or commercial vehicle. It would likely prove particularly appealing to serious automotive enthusiasts interested in custom parts and accessories for their vehicles.
The appealing features of the system according to the present disclosure would be its unusual design and automobile customization. Instead of always hearing a dull and lifeless buzzing or dinging noise when a car door was opened, this product would sound a message or sound to be enjoyed by all. This would take some of the monotony and boredom out of original factory equipment to add new life and appeal to the parked car or truck. The product would attract the immediate attention of others to personalize and accessorize the vehicle in a fun and interesting manner.
Those skilled in the art can now appreciate from the foregoing description that the broad teachings of the present disclosure can be implemented in a variety of forms. For example, programming the base unit can be accomplished from a CD or CB player that can be placed in the glove box of a vehicle. Therefore, while the vehicle door opening indicator system of the present disclosure has been described in connection with a particular example thereof, the true scope of the disclosure should not be so limited since other modifications will become apparent to the skilled practitioner upon a study of the drawings, specification and claims that follow.
