In addition, the user can store the predetermined voice information through the microphone 150 for collecting a predetermined voice, the recording switch 155 for electrically connecting the microphone 150 and the sound source chip 140 to the sound source chip ( Not only the voice information previously stored in 140, but also voice information stored by the user may be reproduced through the speaker 120.

A structure and a process of assembling the housing accommodating the printed circuit board configured as described above will be described with reference to FIGS. 4 and 5.

First, the housing is preferably composed of the first housing 300 and the second housing 400 are detachably coupled. The main body 310 of the first housing 300 may be, for example, a heart-shaped transparent body or a translucent body, and a cylindrical speaker accommodating part 350 accommodating the speaker 120 is formed at the center of the main body. A plurality of sound emission holes 360 are formed at the bottom of the speaker accommodating part 350, and a step 365 is formed to support the speaker 120 at a predetermined height from the bottom.

In addition, a pair of first bosses 375 protrude from the bottom surface of the first housing 300 at a predetermined interval, and an insertion pin 370 is formed at an upper end of the first boss 375 to form a printed circuit board. On both sides of the upper part, a guide hole 160 is formed to accurately attach the printed circuit board to the first housing 300. When the guide hole 160 coincides with the insertion pin 370 of the first housing 300, the printing is performed. The circuit board is attached to the first housing 300.

A microphone insertion hole 330 is attached to a bottom of the first housing 300 to attach a recording microphone 150 used for recording voice, and a recording microphone 150 is provided at a side of the first housing 300. And a recording switch hole 340 for attaching a recording switch 155 for forming a closed circuit between the sound source chip 140 and the first housing 300 at both sides of the power supply part 200. Consists of a protective cover 320 to protect the lead 130 for supplying power to the sound source part (100).

On the bottom of the second housing 400, a pair of second bosses 420 having an insertion hole 425 formed therein is formed, and the insertion pin 370 of the first housing 300 is connected to the second housing 400. The insertion hole 425 is inserted into and coupled.

The operation of the voice generator according to the embodiment configured as described above will be described with reference to FIGS. 1 to 3 as follows.

In order to emit the voice stored in the sound source chip 140 to the outside or to store a predetermined voice in the sound source chip 140, the power source part 100 is connected to the power supply part 200 first. Power on.

However, the power supply path is short-circuited between the sound source part 100 and the power supply part 200, so that when the user holds the lead 130 located on both sides of the heart-shaped housing by the user, a conductive path is formed through the user's body. Thus, a power supply path is formed.

When power is supplied to the sound source chip 140 through the above-described path, the controller 141 determines whether the microphone 150 and the sound source chip 140 are electrically connected.

If the sound source chip 140 is not electrically connected as a result of the determination, the controller 141 transmits a signal to output the voice to the memory 142.

The memory 142 outputs predetermined voice data to the digital / analog converter 145 according to the control signal, and the digital / analog converter 145 converts the voice data transferred from the memory 142 into an analog signal. The audio data is then output to the amplifier 146.

Then, the amplifier 146 amplifies the voice data applied by the digital-to-analog converter 145 to output to the speaker 120.

The speaker 120 inputs the voice data output from the amplifying unit 146 to reproduce the voice data as a voice that can be recognized by the user, and also emits light having one end electrically connected to the sound source chip 140 and the other end grounded. The diode 240 also emits light at the same time as the driving of the sound source chip 140.

At this time, the voice output to the outside of the speaker 120 is resonated in the space between the speaker 120 and the step 365 inside the speaker housing 350 of the first housing 300, the speaker housing 350 It is emitted to the outside through a plurality of sound emitting holes 360 formed on the front of.

On the other hand, if the microphone 150 and the sound source chip 140 is electrically connected as a result of the determination of the controller 141, the controller 141 stores the voice signal input from the microphone 150 in the memory 142.

This will be described in more detail as follows.

After the power is supplied to the sound source chip 140, the user switches the recording switch 155 located inside the recording switch hole 340 on the side of the first housing 300 to record a predetermined voice. When pressed, it is electrically connected, and a closed circuit is formed between the microphone 150 and the sound source chip 140.

In this state, a voice capable of expressing a user's unique personality is transmitted to the microphone 150 located at the bottom of the front body 310 of the first housing 300, and the microphone 150 picks up the voice to produce a predetermined voice. It is converted into electrical energy and then output to the sound source chip 140.

The voice signal output from the microphone 150 is transmitted to the compensator 144 of the sound source chip 140, and the compensator 144 amplifies the voice signal input from the microphone 150 and then filters the frequency signal of a predetermined band. Only the analog / digital converter 143 is transmitted.

The analog / digital converter 143 inputs the voice signal transmitted from the compensator 144 to convert the voice signal, which is an analog signal, into a digital signal and delivers the voice signal to the memory 142.

Then, the memory 142 stores the voice data changed into the digital signal according to the control signal of the controller 141.

In some cases, the voice data previously stored in the memory 142 may be deleted and new voice data may be recorded, or the old voice data and the new voice data may be stored together.

In the above described the present invention with reference to a specific preferred embodiment, the present invention is not limited to the above-described embodiment, to those skilled in the art to which the subject innovation belongs within the scope not departing from the gist of the present invention. By this, various changes and modifications can be made.

As described above, a part of the power supply part connected to the sound source part may be protruded by a pair of leads to be installed on both sides of the housing and to form conductive paths between the leads, thereby outputting a voice signal stored in the memory. Thus, for example, when couples hold one hand and hold each lead with the other hand, a conductive path is formed between the leads, so that a voice signal such as 'I love you only' or 'I LOVE YOU' is outputted. It can inspire you.

In addition, there is an advantage in that the light emitting diode is turned on at the same time as the output of the voice signal, so that the housing body which is a translucent body can be made to shine lightly.

Furthermore, there is an advantage that the sound source part for storing the predetermined sound or reproducing the stored sound and the power supply part for supplying power to the sound source part can be mounted on a single printed circuit board and stored in the housing, thereby making it compact.
