Description

Lost child necklace {lost child with necklace}

It is for quick response and prevention in case of a child's loss by recording contact information suitable for the situation when children go out.

The present invention relates to voice recording and reproducing, and more particularly, to a digital voice recording and reproducing apparatus.

In general, anti-lost necklaces use names and phone numbers on the back of a silver or steel product and are worn on the child's neck or arm, so that children's parents' voices can be used to contact and address the child's parents. It was devised in the form of recording and playback.

The purpose of the present invention is to combine the digital voice recording and reproducing device to prevent the loss of children's toys to automatically know the house address and phone number in the form of toys and to be a quick measure in the event of a loss.

Specific means for achieving the object of the present invention is as follows. The necklace for preventing the loss of the cord 12 is connected to the safety pin (11) position and press the switch (recording) (2), the lighting lamp (7) is turned on The voice input is input from the microphone (4), the difference between the microphone reference voltage (10) and the voice input from the amplifier (8) is filtered by the filter (9), stored in the IC (MPU) flash memory (1), and switched (playback). (3), the audio signal stored in the IC (MPU) flash memory 1 is filtered by the filter 9, amplified by the amplifier 8, output through the speaker, and supplied with power according to the requirements of the above functions. A preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings as follows. As shown in FIG. 1, the string decoration 12 is connected to the safety pin 11 position and the switch When (2) is pressed and the lamp (7) is lit, the protector If the name, telephone number, address, etc. of the child's personal information are spoken, the electrical signal of the microphone 4 is subtracted from the input of the microphone reference voltage 10 and the amplifier 8, and the electrical signal is filtered out of the filter 9. Filters the noise and stores it in the IC (MPU) flash memory (1) and detects the state of the switch (playback) (3) to filter the audio signal stored in the IC (MPU) flash memory (1) by the filter (9) The amplification at (8) is configured to output through the speaker 5. The operation principle of the present invention configured as described is as follows. Open the anti-collar necklace and the cord decoration (12) to the safety pin (11) If you don't connect to the position, you can't record, so if you connect and press the switch (2), the lamp (7) will turn on and you will be ready to record. Playback) (3) It is in the inactive state until the signal is detected, and when the missing child is opened, if you open the anti-mia necklace and press the switch (playback) (3), the recorded contents are output through the speaker (5) and then switch (playback) (3). According to the present invention, the digital voice board and the case have a front 13, a rear 14, an inner 15, and a battery cover. Five kinds of cases in the form of (16), necklace straps (17), strap ornaments (12) are combined to form a mobile phone to be worn on the children's neck.

Currently, children use metals worn on their necks and wrists by writing down contacts and names on their products, which secures the shortcomings that children quickly demonstrate, recording and playing with children's familiar parents' voices. It's designed to be portable and always portable.

Claims (1)

A built-in digital voice recording and playback device, worn on the children's neck can be quickly prevented and prevented in the event of a lost child.
