Description

Multi Talking Doll {Multi talking doll}

This article is about a multi-party talking doll, which can recognize, store or wirelessly transmit sound input from an audio cassette deck, a microphone input device, and an external input device that can input various audio devices. It is a device that selects its contents, RF amplifies, modulates and transmits specific frequencies of airwaves, wirelessly receives them through a doll or robot, and amplifies and demodulates them so that they can talk through various receivers. It is about.

Conventional dolls or robots can simply listen to sounds or connect to wires to hear sound, but this is a wired distance, which limits the distance and inconvenience of users.

In order to solve the problems of the prior art as described above of the present invention, in order to solve the problems of the prior art, a significant part by combining a voice recognition memory system, an external input device and a microphone system in a cassette in a conventional wireless transmission system It is to provide a "multi-party talk doll" that can be used as children's language education and toys, which can be played repeatedly, and the self voice is directly transmitted or recorded and transmitted, and multiple dolls can speak and listen at the same time.

According to the characteristics of the present invention for achieving the above object, educational cassette tape, language cassette tape, and various kinds of voice signals are inputted into the device, edited and played, and the conversation or game between the dolls is carried out using an external input microphone. A tape amplification unit that receives magnetic signals from the tape for enjoyment and converts them into voice signals, and a function control unit that controls various functions such as playing, recording, and repeating the amplified signal, and an analog signal input through a microphone to a certain level. A wireless amplifier comprising amplifying and clicking audio amplification unit, a modulator for carrying various types of voice signals from the cold and external input jacks on a carrier wave, which is a high frequency, and an output unit for amplifying the modulated signals and sending them to each receiving medium. The transmission system provides a "doll that talks to the party".

Referring to FIG. 1, a tape amplification unit 110 for converting a weak magnetic signal input from a tape into a voice signal and a magnetic voice recording unit 150 for recording through a microphone are reproduced or recorded, and a pronunciation comparison function is selected. A function to control the repeating function, the function of comparing the original sound with the user's pronunciation, the control unit 120 to control the IC recording function, etc. and the voice amplifier to amplify the voice to be heard by the speaker 160 and the crystal oscillator to generate a predetermined firing frequency A frequency multiplier 210 and a tape for amplifying the high frequency of the frequency generated from the crystal oscillation unit 220 so that the oscillation frequency of the crystal oscillator does not change due to load variation in the power amplifier unit and raises it to a predetermined frequency. Radiating the modulated signal 250 and the modulated signal sufficiently mixed with the low-frequency, such as signal and microphone to the high frequency generated above It can be made of a power amplifier 230 for amplifying to.

FIG. 2 illustrates that when an acoustic signal generated by a transmitter is received through an antenna at a wireless receiver 310 and output at an intermediate frequency IF, the receiving acoustic demodulator 320 processes acoustic data to process an acoustic signal of a transmitter. Demodulate

In addition, when the voice modulator 340 amplifies and modulates the analog signal input through the microphone 330, the voice demodulator 350 demodulates the voice signal from the modulated signal. Thereafter, the mixing unit 360 receives the output signals of the reception acoustic demodulation unit 320 and the voice demodulation unit 350 and adjusts the ratio or the intensity of the broadcasting voice and the magnetic voice according to the control signal of the control unit 370. When adjusted and output, the amplified by the sound amplifier 380 and output to the speaker 390, the user hears the sound through the wireless receiver built in the doll or robot.

The present invention is a device for controlling and operating a wireless talking doll in the transmission unit due to the above operation allows children to play and learn as a multi-party talking doll.

As described above, the 'multi-party conversation doll' of the present invention induces interest by integrating educational contents by integrating educational contents with multiple dolls talking to each other and talking to children, and it is effective for parents to care for young children. There is.
