Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photo mount with a voice recording / playback device, in which a voice recording / playback circuit is provided on the back of a photographic panel or mount.

[0002]

2. Description of the Related Art A photo mount with a sound generator, and a mount in which an electronic circuit for sound reproduction (generation) is incorporated on the back side of a photo panel or a mount is described in, for example, Japanese Utility Model Publication No. 2-44783. In this case, a predetermined voice is recorded (recorded) in a ROM or the like, and the voice is exclusively reproduced. Then, this is usually a circuit pattern formed on a printed circuit board such as glass epoxy, the circuit pattern is plated with gold, and a memory IC such as a ROM for recording the voice or a bare chip of various ICs is mounted to produce a voice. The electronic circuit is configured.

[0003]

As described above, as a conventional photo mount with a sound generator, a predetermined sound is previously recorded (recorded) in a memory IC such as a ROM. A voice reproduction electronic circuit including a memory IC is formed on a printed circuit board and installed on the back surface of the mount. However, these mounts are for audio reproduction only, and the end user must connect the mount to a special recording device for recording, and erase the memory that recorded the voice,
It is not possible to record new audio while looking at the picture.
Therefore, it is good to distribute a large number of fixed sounds with a fixed photo as a mount that can be played back, but it is also possible to record and delete various sounds with various photos, and then change the sound according to the purpose. The problem is that this mount cannot be used.

[0004]

SUMMARY OF THE INVENTION The present invention has been made for the purpose of solving the above problems, and is an electronic device including a memory circuit for recording and reproducing sound on a panel or a mount, an oscillation circuit, an amplification circuit. A photo mount with a sound recording and reproducing device, which is configured by a circuit, a piezoelectric speaker that also serves as a microphone, and a battery.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view showing the overall construction of a photo mount with a sound recording / reproducing apparatus using the present invention, FIG. 2 (A) is a plan view thereof, FIG. 2 (B) is a side sectional view, and FIG. 3A is a plan view of the audio recording / reproducing unit, FIG. 3B is a side sectional view thereof, and FIG. 4 is a block diagram of an electronic circuit.

In FIG. 1, reference numeral 1 is a main body of a photo mount or panel with a voice recording / reproducing device (hereinafter referred to as a mount), which has a frame 2 on its surface, which can be viewed through a window 3 surrounded by the frame 2. Then, the target photograph P is pasted. When push button switch 4A is pressed, the power turns on,
If the recording / reproducing switch (push button switch) 4B is in the reproducing mode, the target sound is reproduced (generated) from the speaker 7. When the recording / reproducing switch 4B is pressed to enter the recording mode, the speaker 7 functions as a microphone, and when a sound is emitted toward the speaker 7, the sound can be recorded and used as a chat photo. That is, the recording / reproducing switch 4B is used for switching between the recording mode and the reproducing mode.

The part indicated by the dotted line in FIG. 2A is the audio recording / reproducing section 5, which is shown in detail in FIGS. 3A and 3B, and is incorporated in a part of the inside of the mount main body. Therefore, the mount main body has a certain thickness as shown in the side sectional view of FIG. The audio recording / playback unit 5 is made of resin in a plate shape,
As the resin, ABS resin, phenol resin, vinyl chloride resin, or the like is used.

A thin speaker 7 using a piezoelectric element or the like is attached to the flat surface portion 6 of the voice recording / reproducing portion 5, and the flat surface portion 6 provides the effect of a diaphragm for expanding the voice. .. The speaker 7 is used as a microphone function during recording. Of course, the speaker 7 is electrically connected to an electronic circuit described later. In addition, in the lower part of the audio recording / reproducing unit 5 shown in FIG.
As shown in the sectional view of (B), there is a hollow protruding portion 8,
A thin battery 9 as a power source, a push button switch 4A, and a recording / reproducing switch 4B are installed here. It is preferable to use a lithium battery as the battery 9 in terms of thinness and life.
And push button switch 4A, recording / reproducing switch 4B
The head is placed on the surface of the mount 1 so that buttons can be easily operated.

An audio recording / reproducing electronic circuit (hereinafter simply referred to as an electronic circuit) 10 according to the block diagram shown in FIG. 4 is installed on the surface of the protruding portion 8, and the push button switch 4A is provided.
And by operating the recording / reproducing switch 4B,
10 is activated to record a desired sound or reproduce the recorded sound, and the photo mount with the sound recording / reproducing device operates.

The electronic circuit 10 has conventionally used a printed circuit board made of glass epoxy resin or the like having a circuit pattern plated with gold. However, glass cloth, non-woven fabric equipment epoxy resin copper clad laminate
It is more effective in terms of cost, thickness, thermal efficiency and the like to use (CEM) and use a printed circuit board made of a composite base material on which an electronic circuit pattern is plated with nickel, which is cheaper than gold plating. Then, an oscillator circuit IC12, an amplifier circuit IC13, a control IC14 and an EEPROM, an EPROM memory IC11, etc., which constitute an audio recording / reproducing electronic circuit, are mounted on this printed circuit board by a bare chip,
These are electrically connected by the wire bonding technique to form the electronic circuit shown in the block diagram of FIG. As the voice recording memory used here, in addition to the rewritable (recordable) EEPROM and EPROM described above, an SRAM having a backup power supply may be used according to the purpose, but a flash memory is used. It is also effective. The capacity of these memories determines the recordable time of the voice to be recorded. Further, as described above, since the piezoelectric speaker 7 is also used as a microphone, the electronic circuit of FIG. 4 is switched between recording and reproducing by operating the recording / reproducing switch 4B, and the function of the speaker 7 can be selectively used. .. In this way, a photo mount capable of recording or reproducing sound is configured.

[0011]

As described above, the conventional photo mount with a sound generator has only a device for reproducing sound, but according to the present invention, the problem of reproducing sound is replaced by a ROM instead of an electronic circuit. The problem is solved by using a rewritable memory IC such as an EEPROM, and it becomes possible to mount a photographic mount on which various sounds can be recorded and reproduced with various photographs, and sounds to be recorded later can be changed. ..

Also, the final user can easily record without using a writing device or the like separately.
