Description

A voice message recording and retrieving system

The present invention relates to a voice message recording and reproducing system. In particular, the present invention relates to a voice message recording and reproducing system incorporating a predetermined circuit having a function of recording, reproducing and erasing a voice message in a case of a business card case.

There has been prior art related to the present invention. For example, when you unfold a Christmas card, you can automatically play Christmas music recorded on a chip embedded in the card. However, these cards were unidirectional. That is, the sender could only send the message unilaterally to the recipient, but could not send a reply message to the sender.

And these cards did not allow the sender to freely record the messages they wanted, and when the card was manufactured, a large number of specific messages were recorded, and the consumers purchased and opened the cards to play the messages automatically.

Today, there is a need for the emergence of a recording medium capable of bidirectional message transmission. In other words, there is a need for a voice message recording medium capable of repeatedly recording and reproducing a message that has not been possible in the past.

Of course, there is also a recorder in the past it was possible to record and play back messages. The recorder, however, was power intensive because it was bulky and required a small motor to wind the tape. In order to deliver the message to the other party, only the tape had to be delivered. However, these tapes had a lot of unnecessary points. First, the bulky, analog, power-consuming power required to change or recharge the batteries frequently. This is quite uncomfortable and cumbersome for modern people.

That is, modern people are feeling the need for a recording medium that can use less power, smaller size, thin thickness, low price, and can check and reply to the message of the other party without having to carry their own recorder.

The present invention was devised to solve various problems of the related arts, and it is an object of the present invention to disclose a system for repetitively recording and reproducing voice messages and retrieving and deleting data.

Other advantages and features of the present invention will become more apparent upon reading the following detailed description of the invention and with reference to the accompanying drawings.
