A schematic block diagram of the signal output system is shown, and FIG. 4 is a flowchart illustrating a method of controlling a recordable audio output picture frame according to the present invention.

Referring to FIG. 1, a photoresist (Cds (Cadmium Sulphide)) 102 is placed at a predetermined position on the front surface of a conventional frame 101 manufactured by a plastic injection method, a wood processing method, a mold injection method, or the like. The through hole 103 for insertion is formed to penetrate the front part and the back part of the picture frame 101.

In addition, the front portion of the through hole 103 allows the external light to be easily focused on the photoresist 102, and at the same time, the light condensing and protective cover to prevent the photoresist 102 from malfunctioning due to external impact or dust. It is closed by a lens 104 that plays a role. In this case, the lens 104 may be replaced with a glass or transparent material through which light may pass.

2, the printed circuit board 105 is coupled to the coupling hole 107 of the picture frame 101 by a fixing member 106 such as a screw.

The printed circuit board 105 is provided with a voice signal output device. The voice signal output device includes a conventional voice integrated circuit 108, a battery 109, a speaker 110, a microphone 111, and a recording switch. 112 and a memory 113.

Here, referring to FIG. 3, the audio signal output device will be described in more detail. The battery 109 supplies driving power required by the system.

The photoresist 102 varies in resistance according to the intensity of light received from the outside, and outputs a voltage level determined according to the resistance to the detection terminal Detect of the voice integrated circuit 108. Here, when external light is received by the photoresist 102, the photoresist 102 has an arbitrary resistance value corresponding to the intensity of the received light, but when the external light is blocked, the resistance of the photoresist 102 is infinite ( ∞ Since the driving power supplied from the battery 109 is not provided to the detection terminal Detect of the voice integrated circuit 108, the detection terminal Detect of the voice integrated circuit 108 is in a logic "low" state. .

The recording switch 112 switches the voice integrated circuit 108 to the recording mode so that when the voice information is input through the microphone 111, the voice switch circuit 108 can be stored in the memory 113. That is, as the user operates the recording switch 112, the driving power supplied from the battery 109 is supplied to the recording switch input terminal RSin of the voice integrated circuit 108 through the recording switch 112, and the voice integrated signal is collected. The circuit 108 selectively performs the recording mode and the playback mode according to the voltage level of the recording switch input terminal RSin. At this time, when the user operates the recording switch 112, since the voltage level of the recording switch input terminal RSin is a logic "high" state, the voice integrated circuit 108 is switched to the recording mode, and the user records the recording switch 112. When not operating the audio switch circuit 108, it is preferable to set the audio integrated circuit 108 to switch to the playback mode because the voltage level of the recording switch input terminal RSin is a logic " low " state.

The voice integrated circuit 108 stores the voice signal of the user input through the microphone 111 in the memory (RAM) 113 and simultaneously outputs the voice signal stored in the memory 113 to the speaker 110. Perform the process. For example, the voice integrated circuit 108 modulates the voice signal input through the microphone 111 to store the memory signal in the memory 113 and demodulates the modulated and recorded voice signal to the speaker 110. Do the work. The voice integrated circuit 108 checks the voltage level of the detection terminal Detect to which the photoresist 102 is connected, and determines whether to output the voice signal stored in the memory 113 according to the result. The voltage level of the recording switch input terminal RSin to which the 112 is connected is checked and the operation of the microphone 111 is controlled according to the result, and at the same time, the voice signal input through the microphone 111 is stored in the memory 113. To do the job. In particular, the voice integrated circuit 108 is reset when the voltage level of the detection terminal Detect is logic "low" compared to the reference level, and the voltage level of the detection terminal Detect is logic "high" compared to the reference level. When switched to the audio information stored in the memory 113 is output to the speaker (110). In addition, a general oscillation element 114 (for example, a crystal oscillator) is mounted in the voice integrated circuit 108 to use a clock generated by the oscillation element 114 as a system clock.

In another similar embodiment, the counter 115 is added to the voice integrated circuit 108, and the voltage level of the detection terminal Detect of the voice integrated circuit 108 is switched to a logic " low " state relative to the reference level. It resets at the same time and starts counting operation for the system clock.When counting voltage level of the detection terminal (Detect) is changed to logic "high" state, the counting operation is stopped and the counting value is compared with the preset reference value. For example, the voice information stored in the memory 113 may be output only when the counting value is less than or equal to the preset reference value. This is because the voice integrated circuit 108 is reset due to no light being received by the photoresist 102 when the user is out or in a dark place, and the user turns on indoor lighting or moves to a bright place after a long time. Therefore, to prevent the output of unwanted voice information. In this case, the reference value is preferably set to several times or tens of times the counting value.

Referring to Figure 4 with respect to the operation of the present invention having such a configuration as follows.

When the user operates the recording switch 112 to record the voice to be output, the driving power supplied from the battery 109 is supplied to the recording switch input terminal RSin of the voice integrated circuit 108 to record the input switch. The potential level of (RSin) is inverted to a logic "high" state (S1). Accordingly, the voice integrated circuit 108 is switched to the recording mode (S2).

Thereafter, when the user inputs a voice to be recorded through the microphone 112, the voice integrated circuit 108 modulates the input voice signal and stores the voice signal in the memory 113 (S3). After that, when the recording operation is completed (S4), the voice integrated circuit 108 releases the recording mode and returns to the initial state.

If the user does not operate the recording switch 112, the driving power is cut off to the recording switch input terminal RSin so that the potential level becomes a logic " low " state. The voice integrated circuit 108 checks the potential level of the recording switch input terminal RSin, and if it is determined that it is not the "high" level, switches to the voice signal reproduction mode (S5).

Here, when the user blocks the light supplied to the photoresist 102 by covering the lens 104 installed on the front of the frame 101, the resistance value of the photoresist 102 increases to infinite ( ∞ Since the resistance value is close to), the detection terminal Detect of the voice integrated circuit 108 takes a voltage lower than a predetermined reference voltage, that is, a logic "low" level. The voice integrated circuit 108 checks whether the voltage level applied to the detection terminal Detect is a logic "low" level (S6), and resets the voice integrated circuit 108 when it is determined that the check result is a logic "low" level. At the same time, the counting operation of the counter 115 is started (S7).

Subsequently, when the user releases the covering state of the lens 104 installed on the front of the frame 101, external light is collected by the lens 104 to reach the photoresist 102. Accordingly, the photoresist 102 has a resistance value corresponding to the amount of light condensed by the lens 104, so that the detection terminal Detect of the voice integrated circuit 108 has a voltage higher than a predetermined reference voltage. The logic will take a "high" level. The voice integrated circuit 108 checks whether the voltage level applied to the detection terminal Detect is switched to the logic "high" level (S8), and when it is determined that the check result is switched to the logic "high" level, the counter 115 The counting operation is stopped (S9) and the counting value is compared with the preset reference value (S10).

If the counting value is greater than the reference value in this step 10 (S10), this means that the user is moving from a dark place to a bright place or when he goes out and returns home after sunset to turn on a light source such as a light. Since the output function is not desired, the voice integrated circuit 108 stops the voice signal reproducing mode and returns to the initial state.

If the counting value is equal to or smaller than the reference value in step 10 (S10), the voice integrated circuit 108 demodulates the voice signal stored in the memory 113 and outputs it to the speaker 110 (S11). Accordingly, the speaker 110 outputs the corresponding voice recorded by the user.

Meanwhile, a function of performing a counting operation in the above-described operation flow process to compare the counting value with a preset reference value and executing or canceling the voice signal reproduction mode according to the result is an additional element of the present invention.

Therefore, the user can play the voice input by the user, thereby feeling a friendly feeling. In particular, by mounting the lens 104 on the front surface of the frame 101 to collect external light and supply it to the photoresist 102, malfunction due to dust or the like can be prevented in advance. In addition, since the amount of light collected by the lens 104 is detected more than when integrated exposure to external light, the resistance value of the photoresist 102 can be sufficiently reduced to increase the reliability of the operation.

As described above, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined by the claims below and equivalents thereof.

As a result, according to the recordable audio output picture frame and the control method thereof, the following advantages occur.

First, the user can directly record an arbitrary voice, and by playing the voice recorded by the user, a more friendly feeling can be felt.

Second, the stored voice is output as the user blocks the light supplied to the lens in close proximity to the adjacent point from the position where the frame is installed, so that the user does not have to directly touch the frame, so that the voice playback operation can be performed more conveniently. And it can improve the cleanliness by not contacting the user.

Third, by attaching a lens to the front portion of the picture frame to collect external light and supply it to the photoresist, malfunction due to dust or the like can be prevented in advance.

Fourth, since the amount of light collected by the lens is detected more than when integrated exposure to external light, the resistance value of the photoresist can be sufficiently reduced, thereby increasing the reliability of the operation.
