Also, the ultrasound sensing unit 200 may be provided with a USB port, and the received ultrasound information may be stored in the USB.

Hereinafter, the functional configuration and operation of fetish device 300 will be described with reference to Figs. 8 and 9. Fig.

8 is a block diagram of a fetish device according to the present invention. 8, the contents providing unit 100 of the fetish apparatus 300 according to the present invention includes a content output unit 130, a control unit 144, a memory 145, and a communication unit 146. [ The control unit 144, the memory 145, and the communication unit 146 may be formed on the main PCB 140 in the form of a chipset or a circuit, or may have a separate component or the like. Although the control unit 144, the memory 145 and the communication unit 146 are included in the content providing unit 100 in FIG. 8, the content providing unit 100 or the ultrasonic sensing unit 200 ) And a separate independent configuration.

The content output unit 130 outputs auditory, visual, and tactile content generated by the control unit 144. The content output unit 130 may include a speaker 131, an illumination unit 133, and a vibration unit 135, as described above. The operation of the content output unit 130 is controlled by the control unit 144. [

The control unit 144 controls the overall operation of the content providing unit 100 and converts ultrasound signals provided from the ultrasound sensing unit 200 into auditory, visual, and tactile content. Specifically, the control unit 144 converts the ultrasonic signal into a sound signal of an audible frequency band to generate auditory contents, and converts a sound signal of an ultrasonic signal or an audible frequency band into a light and a vibration signal to generate visual and tactile content .

As a method for the controller 144 to convert an ultrasonic signal into a sound signal in an audio frequency band, for example, a method using a frequency divider circuit and a method using a mixer circuit can be used. In this case, a corresponding circuit may be configured on the main PCB 140 or the like.

Since the frequency band of the ultrasonic signal is a band that can not be heard by the human ear, the frequency band of the ultrasonic signal should be lowered to the audio frequency band (20 Hz to 20 kHz).

First, when the frequency divider circuit is used, the inputted ultrasonic signal can be lowered to 1 / n (n is an integer). For example, when dividing 20kHz to 40kHz by 1/2, it is possible to convert to an audible frequency band of 10kHz to 20kHz.

Alternatively, when a mixer circuit is used, for example, when the third signal S2 is mixed with the heartbeat ultrasonic signal S1 of the fetus, the S1? S2 signal is generated. After removing the S1 + S2 signal through the filter, only the S1-S2 signal remains. Therefore, by setting the S2 signal in accordance with the frequency band of the ultrasonic signal, the ultrasonic signal can be adjusted to the audible frequency band. For example, when the S1 signal is 30 kHz to 40 kHz and the S2 signal is 25 kHz, the signal output through the mixer circuit is a signal (S1-S2) of 5 kHz to 15 kHz and a signal (S1 + S2) of 55 kHz to 65 kHz. At this time, when the signal (S1 + S2) of 55 kHz to 65 kHz is removed through the filter, only the signal of 5 kHz to 15 kHz is left, so that the signal of the audible frequency band can be obtained.

Next, a method of converting an ultrasonic signal or a sound signal of an audio frequency band into vibration and light can be performed by referring to a set value mapped with respect to a frequency value and an amplitude of the input signal. For example, the vibration information such as the kind of the vibration to be outputted, the pattern, the intensity, and the vibration occurrence time are mapped and stored in advance according to the frequency value and the amplitude of the input signal and then converted into an ultrasonic signal or an audible frequency band It is possible to convert the signal into a vibration signal mapped to each unit of the signal. Similarly, the illumination information such as the color, brightness, and light emission time of the light to be output with respect to the frequency value and the amplitude of the input signal are mapped and stored in advance, and then the ultrasound signal of the heartbeat sound or the unit It is possible to convert the illumination signal into a mapped illumination signal. In addition, depending on the composition of the sound signal (or sound source signal), the type of light can be set, for example, the melody maps to the color of the light, the rhythm corresponds to the intensity of the light (illumination) It is possible to map to the color scheme.

In this way, the operation of the controller 144 to convert ultrasonic signals into sound, vibration, and light may be performed through a hardware configuration such as a chipset or a circuit, or may be processed in a software manner by a separate program. Preferably, it may be implemented on the main PCB 140 to operate through a hardware configuration, such as a circuit, to speed up processing.

In addition, information necessary for the controller 144 to convert ultrasound signals into audible, visual, and tactile content may be stored in the memory 145. [ For example, the memory 145 stores reference information for converting an ultrasonic signal into a sound signal in an audible frequency band, that is, a reference value (an n value to divide the input signal in the case of the frequency division circuit, Signal, etc.), vibration information and illumination information for converting an ultrasonic signal or a sound signal into vibration and light.

Meanwhile, the method of converting the ultrasound signal into the audio signal of the audible frequency band, or converting the ultrasound signal or the sound signal into vibration or light is merely an example, and in addition to the above method, Of course it is. In addition, since there are various well-known technologies for converting ultrasound signals into corresponding sounds, vibrations, lights, etc., further explanation is omitted.

The control unit 144 controls the content output unit 130 to output the converted content. On the other hand, the control unit 144 can control auditory, visual, and tactile content to be output together with each other. For example, when the heartbeat sound or music of the fetus is output through the speaker 131 of the content output unit 130, the controller 144 controls the illumination unit 133 and / Can be output together through the vibration unit 135. [ Therefore, it can provide psychological stability and pleasure of pregnant women and fetus.

The memory 145 is connected to the controller 144 and stores information necessary for the operation of the controller. Specifically, the memory 145 stores the reference information (reference value) for converting the ultrasonic signal into the audio signal of the audio frequency band, the sound signal of the ultrasonic signal or the audio frequency band, Vibration information, illumination information, and the like. In addition, the memory 145 may store a program or a set of commands necessary for the operation of the controller 144. The memory 145 may also store auditory, visual, and tactile content generated by the control 144. The memory 145 is a computer-readable recording medium and may be installed locally or remotely. The memory 145 may be a flash memory, a random access memory (RAM), a hard disk, or any digital storage medium.

 The communication unit 146 supports data communication with an external device such as the mobile device 400. [ The communication unit 146 may support various communication schemes, and preferably supports a short-range communication scheme. The communication unit 140 can support Wi-Fi, Wi-Fi direct, Bluetooth, ZigBee, and the like in a short distance communication mode. The communication unit 145 may transmit the auditory, visual and tactile content generated by the control unit 144 to the mobile device 400 or the like. In addition, when the fetish device 300 according to the present invention, in particular, the contents provider 100 operates as a Bluetooth speaker or a Wi-Fi speaker, the communication unit 146 receives the sound source information from an external device such as the mobile device 400 To the control unit 144. [

FIG. 9 is a diagram illustrating a signal conversion process of a fetish device according to the present invention, and particularly, a signal flow in signal conversion and sound output of a content providing unit 100. All or a part of the sound source converter 147a, the illumination converter 147b, the vibration converter 147c, the DAC 148 and the amplifiers 149a and 149b in the configuration shown in Fig. As shown in FIG. All or a portion of the input ports 142a and 142b, the sound source converter 147a, the light converter 147b, the vibration converter 147c, the DAC 148 and the amplifiers 149a and 149b may be on the main PCB 140 Lt; / RTI >

First, when the ultrasonic sensing unit 200 and the contents providing unit 100 are connected by a cable or the like, the ultrasonic signal sensed by the ultrasonic sensing unit is received through the input port 142b, and the received signal is transmitted to the sound source converter 147a. And is converted into a sound signal of an audio frequency band. Since a signal using an ultrasonic signal as a source may have a weak signal intensity when outputting to a speaker, the signal is amplified first through an amplifier 149a, then amplified again through an amplifier 149b, do.

The ultrasound signal input to the input port 142b is converted into an illumination signal, that is, time content via the illumination converter 147b, and the converted time content is output through the illumination unit 133. [

The signal output from the illumination converter 147b or the ultrasonic signal input to the input port 142b is input to the vibration converter 147c and converted into a vibration signal, that is, tactile content. The converted tactile content is outputted through the vibration unit 135. [

It goes without saying that the sound signal converted by the sound source converter 147a may be input to the illumination converter 147b or the vibration converter 147c instead of the ultrasound signal input to the input port 142b.

9, an ultrasonic signal is input through the input port 142b. However, the ultrasonic signal may be received through the communication between the ultrasonic sensor 200 and the communication unit 146. FIG. In this case, since the received ultrasonic signal is a digital value, it can be converted into an analog value through the DAC 148, and then input to the sound source converter 147a, the illumination converter 147b, and the vibration converter 147c.

When the fetish apparatus 300 according to the present invention receives and outputs a sound source from the mobile device 400 or the like, the sound source signal output from the mobile device is transmitted to the communication unit 146 or the input port (142a).

First, when the mobile device 400 and the contents providing unit 100 are communicatively connected, a sound source signal output from the mobile device is received through the communication unit 146. Since the received sound source signal is a digital value, the received sound source signal is converted into an analog value via the DAC 148, amplified by the amplifier 149b, and output through the speaker 133. [

The sound source signal received through the communication unit 146 is input to the illumination converter 147b and the vibration converter 147c to be converted into time content and tactile content. The lighting converter 147b and the vibration converter 147c generate the visual content and the tactile content in accordance with the sound source signal. The converted time content is output through the illumination unit 133 and the tactile content is output through the vibration unit 135. [ On the other hand, the sound source signal may be converted to an analog value through the DAC 148 and then input to the illumination converter 147b and the vibration converter 147c.

Next, when the mobile device 400 and the content providing unit 100 are connected by a cable or the like, a sound source signal output from the mobile device is input through the input port 142a. The input sound source signal is amplified through an amplifier 149b and then outputted through a speaker 131. [ The sound source signal is input to the illumination converter 147b and the vibration converter 147c and converted into time content and tactile content corresponding to the sound source signal and then output through the illumination unit 133 and the vibration unit 135 do.

FIG. 10 is a flowchart illustrating an operation procedure of a fetish device according to the present invention. Hereinafter, the operation of the fetish device according to the present invention will be described with reference to FIG.

In a state where the contents providing unit 100 and the ultrasonic wave sensing unit 200 are combined, the user separates the ultrasonic wave sensing unit and contacts the abdomen of the pregnant woman.

The ultrasound sensing unit 200 senses the heartbeat sound ultrasonic signal of the fetus, and the sensed ultrasonic signal is transmitted to the contents providing unit 100 (ST100).

The control unit 144 of the content providing unit 100 converts the received ultrasonic signal into a sound signal of an audible frequency band and amplifies the sound signal (ST110, ST120). As described above, the controller 144 can convert the ultrasound signals into the audio signals of the audible frequency band using the reference information stored in the memory 145. The amplified sound signal (auditory contents) is output through the speaker 131 (ST130).

Meanwhile, the controller 144 of the content providing unit 100 converts the received ultrasonic signal or the converted sound signal into an illumination signal to generate visual contents (ST140). At this time, the controller 144 can generate an illumination signal (visual content) using the illumination information stored in the memory 145. [ The generated time content is outputted by the illumination unit 133 (ST150).

In addition, the controller 144 of the contents providing unit 100 converts the received ultrasonic signal or the converted sound signal into a vibration signal to generate tactile content (ST160). At this time, the control unit 144 can generate a vibration signal (tactile content) using the vibration information stored in the memory 145. [ The generated tactile content is outputted by the vibration unit 135 (ST170).

On the other hand, ST140 to ST170 can be performed simultaneously with ST110 to ST130. That is, the control unit 144 generates a sound signal (auditory content) from the ultrasound signal, generates an illumination signal (visual content) and a vibration signal (tactile content) Visual, and tactile content through the speaker 131, the illumination unit 133, and the vibration unit 135. [ Accordingly, the speaker 131, the illuminating unit 133, and the vibrating unit 135 are operated in a complex manner, so that the fetal state is represented by sensible content that a person can feel. Therefore, sympathy can be achieved between pregnant woman and fetus, and the effect of prenatal care can be enhanced.

On the other hand, after the measurement of the heartbeat sound of the fetus is completed, the ultrasonic sensor 200 can be easily and firmly coupled to the contents providing unit 100 by a magnet.

11 is a flowchart illustrating an operation process of the mobile device according to the present invention. 11 may be performed by a user application installed in the mobile device 400. [ Hereinafter, an operation process of the mobile device according to the present invention will be described with reference to FIG.

The mobile device 400 receives the heartbeat sound signal of the fetus from the fetish device 300, particularly the content provider 100 (ST200). The mobile device 400 may be connected or communicatively coupled with the content providing unit 100 via a cable. And communicatively connected through the communication unit 146 of the contents providing unit 100 when the communication is connected. The mobile device 400 receives a sound signal (of an audible frequency band) generated by converting the ultrasonic signal measured by the ultrasonic sensor 200 by the controller 144 of the contents providing unit 100.

The mobile device 400 records the received sound signal as a file (auditory content) (ST210). On the other hand, when the contents providing unit 100 accumulates sound signals until the end of the measurement of the heartbeat sound of the fetus in the form of a file, the mobile device 400 does not separately record a sound signal, Content).

On the other hand, when the control unit 144 of the content providing unit 100 generates and transmits the time and tactile content corresponding to the auditory contents, the mobile device 400 receives the time and tactile content, maps it together with the auditory content, (ST220, ST230).

Then, the mobile device 400 outputs auditory, visual, and tactile content stored at the request of the user (ST 240). Specifically, the mobile device outputs the visual content through the display while outputting the auditory contents through the built-in speaker. Further, the tactile content is outputted through the built-in vibration part. Meanwhile, the mobile device 400 may provide a user interface that allows the user to select a type of content to be output among auditory, visual, and tactile content.

Meanwhile, when a request to transmit a stored content is received from the user, the mobile device 400 displays a list of stored contents to select a content to be transmitted by the user (ST250, ST260). When the user selects the content to be transmitted and selects the other party to receive the content, the mobile device transmits the selected content to the terminal of the selected partner (ST270). Therefore, the content generated through the fetish device 300 can be transmitted and shared to a remote family or the like, rather than simply being used only by a pregnant woman or a family mobile device.
