Abstract

The present invention relates to a toy phone having a voice recording and reproducing function. Specifically, a SMD type masked voice reproducing element using the ADPCM compression algorithm and an ADPCM compression algorithm are used to record and reproduce the voice. The unmasked playback voice recording and reproducing element, which is repeatedly performed, is integrated on a single PCB board to selectively output recorded voices, and can be easily operated through a recording / playback switch unit protruding out of the toy phone. To make it easy for children to learn the two-way calling function of the telephone through the toy telephone, and to record the voice of the parents to provide a more emotional toy than the conventional telephone. In addition, the present invention is a memory and control unit 100 for converting a voice signal input through the recording / reproducing switch unit 40 and the voice / reproducing switch unit 50 and the voice recording microphone 300 is converted to a digital signal and stored therein. And an output control unit for converting the signal into an analog signal and outputting the same through the speaker 200 and controlling each output to be output to one speaker without collision.

Description

Toy Phones with Recording and Playback Functions {.}

The present invention relates to a toy telephone having a voice recording and reproducing element capable of repeatedly recording and reproducing a voice. More specifically, a voice recording and reproducing using a flash memory (RAM) element having an ADPCM type compression algorithm is provided. The present invention relates to a toy phone that implements a learning effect of two-way conversation by using a recording / playback switch protruding from the outside of the toy phone. As a prior art of such a model, as described in Patent Publication No. 1996-007958, it is true that it is economically burdensome to add a cassette tape record function to a toy telephone model and use it as a toy in terms of volume and price. The present invention is very effective in contributing to the increase in sales of the toy phone by using the voice memory device to significantly improve the volume and price commercialized.

The present invention utilizes a flash memory device for recording / reproducing voice by digitally recording and reproducing voice in the conventional analog type recording / playback method described above, which can significantly improve its volume and price, thereby achieving a significant increase in sales. To provide a toy phone.

Hereinafter, a toy phone having a recording and playback function will be described in detail with reference to the accompanying drawings.

The toy phone of the present invention is equipped with a flash memory memory device for recording / playing back a voice to an existing toy phone, which is easy to carry and learns the principle of the two-way call of the phone. Same as As shown in the figure, the recording / playback switch unit 40 is provided to protrude a recording / playback switch unit having a plurality of protruding buttons to perform a function of the present invention in the shape of a conventional portable telephone. For example, the recording button R and the play button P for reproducing the recorded voice from the beginning regardless of the limiting capacity of the memory element, the voice masked with the voice reproducing function And a voice reproducing switch section 50 consisting of buttons for storing and reproducing melody and a convert button C having a function for converting the functions of these two elements. Voice recording is performed through the internal circuit processing through the microphone window 60 designed in the lower part of the toy phone of Figure 1 and outputs the voice and melody through the speaker window 20. Referring to the internal circuit block diagram of the voice memory device 100 of the APR 9000 series used in FIG. 2, an amplifier for amplifying a voice signal input through an input device, an automatic ratio adjusting device for automatically adjusting the amplification ratio, and an input signal Has been significantly reduced in volume, including a digitizer at the input and an analog signal at the output, an inactive memory array representing a memory section that stores the input signal non-destructively, and a switch capacitor filter to remove noise.
