Abstract

The present invention has a compact disc (CD) case in which a voice circuit is built into the compact disc case and a function of recording and playing a record of a record or a story to be shared with fans by a planner's voice is added to the compact disc case. It is about.

Opening the compact disc (CD) case detects the light and automatically plays the recorded contents. It reduces the time to check the contents of the compact disc (CD), listens to the record, listens to the planner's intentions in more detail. Its purpose is to make it understandable.

Description

Compact Disc (CD) Case {CD case}

The creators of compact discs (CDs) record the stories they want to tell fans with the voices of the planners or singers and attach them to the compact disc (CD) cases to play them. have.

When the compact disc (CD) case is shipped, the planner's planning intention is recorded by the singer or the planner's voice. The purpose of this is to improve the quality of the record and to feel the value of the collection by reproducing the CD.

The present invention enhances the value of the collection by upgrading the compact disc (CD) and talks about the planning intention of the planner with the voice of the planner or singer. This is to reduce the time to find a compact disc (CD).

1: IC (MPU), Flash memory 2: Light detection switch

3: battery 4: filter

5: amplifier 6: speaker

Specific means for achieving the object of the present invention is as follows.

The compact disc (CD) case recognizes the signal detected by the light detection switch (2) that senses the external brightness from the IC (MPU) flash memory (1) and inputs the voice to the memory of the IC (MPU) flash memory (1). Is achieved via a battery 3 which outputs through a filter 4, an amplifier 5 and a speaker 6 and supplies power according to the requirements of the functions.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, when the organizer or singer's voice is input to the IC (MPU) flash memory 1 and the IC (MPU) flash memory 1 is input to open the compact disc (CD) case, the light sensing switch 2 Detects light and transmits an electrical signal to the IC (MPU) flash memory (1), and transmits an audio signal stored in the IC (MPU) flash memory (1) to the filter (4). 5) When amplified, the amplifier amplifies the signal and outputs the speaker 6.

Referring to the operation principle of the present invention configured as described above are as follows.

The IC (MPU) flash memory is in the inactive state until the light is sensed by opening the compact disc (CD) case from the light detection switch (2) built into the compact disc (CD) case, and the compact disc (C0) case is When it is opened, an electrical signal is generated in the light sensing switch 2, and accordingly, an electrical signal is input to the IC (MPU) flash memory 1 to generate a preset voice for a predetermined time, and then the sensing signal from the light sensing switch 2 is again generated. It will repeat being in the waiting state until it is entered.

Currently, the compact disc (CD) case is used to store the compact disc (CD). The present invention uses the compact disc (CD) case to store the compact disc (CD). It is designed to feel the collectible value of compact discs.

Claims (1)

A compact disc (CD) case that has a built-in audio playback device in the compact disc (CD) case and opens the compact disc (CD) case to detect light and play back voices.
