1. Field of the Invention
The present invention relates to a greeting card, and in particular to a multimedia greeting card that allows addressees to play a pre-recorded multimedia file by pressing a button.
2. The Prior Arts
Paper greeting cards have been widely used in some occasions, such as graduations, birthday parties, weddings, opening ceremonies, company introduction and other commercial or industrial purposes. Traditional text information generally found on paper greeting cards has been enhanced in electronic greeting cards with multimedia effect.
When holding inaugurations, opening ceremonies or anniversary celebrations, organizers may send invitation cards to invite guests to come to celebration sites, their special features and products will be introduced to attract more participation in the event.
In order to augment the celebration effect, electronic greeting card producers have incorporated a miniature electronic device and a speaker in the electronic greeting cards. When card addressees open up the card, the electronic device begins to playback pre-recorded message to them, such as “we represent . . . and we would like to invite you to the event . . . ” But this new feature is sometimes bothering the addressees who may be only interested in the text information printed on the inside page, or just want to look at the pictures printed thereon without distraction.
Recently, another kind of digital greeting card, which is called E-card and is sent through Email, has been introduced. Although this kind of card can provide a multimedia effect and strengthen its propaganda and specialization, it shall be received and browsed through computers or PDAs, thereby limiting its applications. Besides, the cost for PDAs or similar electronic devices is not economically justifiable for the purpose of creating a multimedia card.
A primary object of the present invention is to provide a multimedia greeting card that employs a button to control playback of pre-recorded multimedia files, thereby allowing addressees to decide whether or not to play the files when looking through the content of the card.
A secondary object of the present invention is to provide a multimedia greeting card having an LCD device and a speaker constructed therein to enhance the multimedia effect.
A tertiary object of the present invention is to provide a multimedia greeting card that is made with simpler design and at far lower cost than conventional PDAs or similar electronic greeting cards.
A further object of the present invention is to provide a multimedia greeting card that allows colorful pictures to be printed on outer surfaces thereof.
To achieve the above-mentioned objects, a multimedia greeting card in accordance with the present invention comprises a speaker, a memory unit, a power supply, a controller, a button, a rectangular frame and a paperboard having multiple folding pages and wrapping around the frame. The frame has multiple holders for holding the speaker, the button, and a circuit board on which the memory unit, the power supply and the controller are installed. An outer folding page of the paperboard has one set of speaker openings and a button opening faced to the speaker and the button, respectively. An adhesive can be alternatively used to obtain secure attachment of the paperboard with the frame. The multimedia greeting card further comprises an LCD device held on a holder of the frame, and the paperboard has a LCD window faced to the LCD device. When pressing the button, it playbacks multimedia files stored in the memory unit through the speaker and the LCD device.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings, which show, for purposes of illustration only, preferred embodiments in accordance with the present invention. In the drawings:

The battery set 18 is electrically connected to the speaker 12, the memory unit 16 and the controller 14, and the controller 14 is electrically connected to the button 20, so as to enable addressees to randomly play multimedia files recorded in the memory unit 16 by pressing the button 20.
Referring to
The outside surfaces of the paperboard 30 may be printed with pictures or colorful printings that can enhance its delicate effect. The paperboard 30 can be further laminated with a transparent protection film, cotton or silk materials to enhance its exquisite texture.

After receiving the multimedia greeting card in accordance with the present invention, addressees may open up the card to read the text messages prepared by the card sender and may also press down the button 20 to play the multimedia files pre-recorded on the memory unit 16. When the button 20 is pressed down, an enable signal is sent to the controller 14, which then reads the multimedia files from the memory unit 16 and transmits audio signals to the speaker 12 for audio playback. Furthermore, the controller 14 can receive multimedia signals through an AV terminal and transform them to multimedia files and then store them in the memory unit 16. Therefore, the card sender can pre-load messages and addressees' favorite music in the memory unit 16.
Unlike conventional electronic greeting cards, which automatically play multimedia files as they are opened, the multimedia greeting card according to the present invention plays the multimedia files only when the button 20 is pressed down, thereby being able to reduce disturbances to addressees.

Referring to
As illustrated above, after receiving the multimedia greeting card in accordance with the second preferred embodiment of the present invention, addressees may open up the card to read the text messages prepared by the card sender and may also press down the button 20 to play the multimedia files pre-recorded on the memory unit 16 though the speaker 12 and the LCD device 50. Furthermore, the controller 14 can receive multimedia signals through an AV terminal and transform them to multimedia files and then store them in the memory unit 16. Therefore, the card sender can pre-load messages and addressees' favorite music in the memory unit 16. It should be noted that the memory unit 16 might be instead of flash memory, such as SD card and CF card, which can be read by card reader, thereby the multimedia files being able to be directly played from SD cards.
In such a manner, the multimedia greeting card according to the second preferred embodiment of the present invention supports multimedia functions in the same way as a PDA or an equivalent electronic device, but the multimedia greeting card is made with simple design and can be produced at a far lower cost than a PDA. Besides, the multimedia greeting card can be printed with delicate patterns, thereby enhancing its attraction.
If the multimedia files are constructed to a multiple menu, the button 20 shall be changed to a group button. Referring to
Referring to
Compared with the conventional greeting cards, the multimedia greeting card in accordance with the present invention can further play multimedia files, such as audio/video files, in addition to the text information printed thereon when it is applied to graduations, birthday parties, weddings, opening ceremonies, company introduction and other commercial or industrial purposes. Addressees are given a choice whether or not to play the multimedia files with the button. Since the multimedia greeting card is made with simple design, so its manufacturing cost shall be considerably lower than a PDA or similar electronic device adapted for such purposes.
Although the present invention has been described with reference to the preferred embodiments thereof, it is apparent to those skilled in the art that a variety of modifications and changes may be made without departing from the scope of the present invention which is intended to be defined by the appended claims.
