I. The technical problem the invention is trying to solve.

The emergence of doll toys having various functions using current electronic circuits means that the doll functions as a toy to the player only when the doll reacts by any action of the player at the stage of the doll simply playing with the doll.

Therefore, almost all dolls are developing various products using various melodies or voices. However, most of these dolls are only occurrences of melodies and development of dolls for new play is required.

All. The gist of the solution of the invention.

In the present invention, when the player kisses the doll, the doll detects the kiss by a pressure sensor mounted on the doll's mouth so that the doll generates a kiss sound.

la. Important uses of the devise

Doll Toys.

Description

A toy doll which wakes sound when she is kissed}

The present invention relates to a stuffed toy, and when the toy is kissed, the doll makes a kiss sound.

Currently, it is a general technique that various music, melodies or voices are outputted by using IC to doll toys which are molded by synthetic resin using slash mold or manufactured by sewing means using fabric.

However, this technique simply makes the player feel bored by simply switching on the music or voice input to the IC.

Therefore, the development of doll toys that respond to the behavior of the player was required.

The present invention is to provide a doll toy to generate a kiss sound when the player kisses the doll toy.

To this end, the piezoelectric element 10 is attached to the mouth of the rod toy, and when the player kisses, the pressure is sensed so that various kiss sounds are automatically generated.

The piezoelectric element is a device using a piezoelectric effect in which a voltage is deformed when a voltage is applied thereto, and conversely, when a physical strain force is applied to the device, a voltage is induced between the electrodes at both ends of the device. Or it is widely used as a sensor for measuring vibration or ultrasonic waves.

Therefore, according to the present invention, different sounds are generated by using different points of voltage generated in the piezoelectric element depending on the strength of the pressure applied to the mouth of the doll.

Hereinafter, with reference to the accompanying drawings will be described in detail the most preferred embodiment of the present invention. First, in describing each of the drawings, the same components have the same reference numerals as much as possible even though they are shown in different drawings.

Doll toy according to the present invention is equipped with a circuit board 20, the IC is formed therein, as shown in Figure 1, connected to the circuit board 20 is operated at a constant pressure piezoelectric element 10 The configuration is attached to the mouth of the doll.

Figure 2 is a block diagram showing a system configuration according to an embodiment of the present invention, the configuration of the present invention is a sensor unit (1) consisting of a piezoelectric element installed in the mouth of the doll toy operated by the user's kiss ;, A sensor sensing unit 2 for receiving an electrical signal from the sensor unit 1 and detecting a pressure value; and receiving an output signal of the sensor sensing unit 2 and comparing the reference signal with a reference value to store the sound stored in the memory unit 4 A controller (3) comprising a one-chip IC for reading one of the data and outputting it as a digital voice signal; a memory (4) consisting of a ROM for storing a plurality of sound data; and the digital output from the controller (3). A D / A converter 5 for converting a voice signal into an analog signal, a low frequency amplifier 6 for amplifying the analog signal, and a speaker 7 connected to the low frequency amplifier 6 and outputting the amplified voice signal It consists of;

In addition, the inside of the doll toy there is a power supply unit (not shown) for supplying power to each component using a 1.5V battery; there is a power switch (not shown); is mounted on the outside.

The sensor unit 1 is to mount the piezoelectric element 10 inside the outer shell of the stuffed toy mouth in order to receive the pressure by the user's kiss accurately, so that different output is generated according to the pressure. Therefore, unlike the doll toy that was conventionally a voice output by using a switch, it is possible to control so that different reactions can be produced according to the user's motion.

The controller 3 receives a pressure value from the sensor detector 2, compares the pressure value with a reference value, and then reads out the corresponding voice data from the memory unit 4 and outputs the corresponding voice data. The A converter 5 is converted into an analog signal and then amplified by the low frequency amplifier 6 to be finally output through the speaker 7.

To this end, in the address of the memory unit 4, different contents stored in the address according to each step are output by the control of the control unit 3 in the state where the different contents are stored. Of course, there is an advantage that can be given to the emotional education according to the provision of the educational aspect.

In the present invention, in addition to the above configuration, a microphone (not shown) and an A / D converter (not shown) may be additionally configured to enable direct voice input from the outside.

3 is an operation flowchart of the present invention, showing in detail the operation of the kissy toy according to an embodiment of the present invention.

When the user turns on the power switch of the doll toy (201), the power value is supplied to each part of the present invention shown in Figure 2 at the same time the pressure value (P) is initialized to "0" (202).

When the user touches 203 the piezoelectric element 10 installed in the mouth of the doll toy while kissing the mouth of the doll toy, the sensor detecting unit 2 measures the pressure value P (204).

The controller 3 receives the pressure value P measured in step 204 and compares the pressure value P when the pressure value P is greater than the lower limit reference pressure value P1 (205) and less than the upper limit reference pressure value P2. The sound data corresponding to the kiss sound stored in the memory unit 4 is determined as a normal input value and is generated through the speaker 7 through an amplification process. If the user kisses too weakly and the pressure value (P) is smaller than the lower limit reference pressure value (P1) in step 206, it is sent to step 202 to proceed from the initialization process again, and the user kisses too hard or with a finger. If the pressure value P is greater than the upper limit reference pressure value P2 in the step 206 by pressing hardly or the like, the control unit 3 corresponds to "pain", "stop", etc. stored in the memory unit 4. The acoustic data is taken and generated (207).

After the kiss sound or the stop request sound is generated through the speaker installed in the doll toy of the present invention as described above, the pressure value P is automatically returned to step 202 before the power switch is turned off 209. It will be initialized to wait for the next input from the user.

The present invention as described above has the advantage that if you kiss the mouth of the doll to provide a new emotional education to the child by the output of a kiss sound or other voice.
