本発明は音発生機能を備えた太陽電池付電子機器に関す

く従来技術及びその欠点〉
近年、小形電子機器の低消費電力化が図られ、小形太陽
電池を電源とするコンパクトでハンディタイプの電子機
器が市場に供されている。BACKGROUND ART In recent years, efforts have been made to reduce the power consumption of small electronic devices, and compact, hand-held electronic devices that use small solar cells as a power source are now available on the market.
即ち、太陽電池を駆動源とする電卓、ゲーム機器の如き
がそれである。That is, such devices include calculators and game machines that use solar cells as a driving source.
一方、これら機器は高機能化を目指し、圧電素子を使用
した音発生機能を具備させたものがあるが、しかしなが
ら、太陽電池を駆動源とする電卓等の機器では音発生時
の消費電力が増大するため実用に供し得ないという欠点
があった。On the other hand, some of these devices are equipped with a sound generation function using piezoelectric elements in an effort to improve their functionality. However, devices such as calculators that use solar cells as their driving source consume more power when generating sound. Therefore, there was a drawback that it could not be put to practical use.
即ち、ここで、太陽電池付電卓に音発生機能を付加した
場合を例にとり説明すると、この電卓は、第１図に示す
ようにＬＳＩ回路１を有し、この回路に太陽電池電源２
と、この電源とＬＳＩ回路間に抵抗３を介して並列に定
電圧用ダイオード４を接続すると共に、さらに発音体５
を接続している。That is, here, an example will be explained in which a sound generation function is added to a calculator equipped with a solar battery.This calculator has an LSI circuit 1 as shown in FIG.
A constant voltage diode 4 is connected in parallel between this power supply and the LSI circuit via a resistor 3, and a sounding element 5 is also connected in parallel.
are connected.
さらにまたキー人力部６及び表示部７を備えている。Furthermore, a key input section 6 and a display section 7 are provided.

オード特性を横軸に電圧（Ｖ）を縦軸に電流（１）をと

次の特性を表わす。In this case, especially when the current consumption characteristics and constant voltage diode characteristics of the LSI circuit are plotted with voltage (V) on the horizontal axis and current (1) on the vertical axis, the result is as shown in Figure 2.In Figure 0, each curve is represents the following characteristics:
Ｔ・・・定電圧ダイオード特性
Ｘ・・・高照度時の太陽電池特性
Ｙ・・・低照度時の太陽電池特性
Ｚ・・・発音時のＬＳＩ消費電流特性
Ｗ・・・非発音時のＬＳＩ消費電流特性次に図について
説明すれば、高照度時は、発音及び非発音時は共にＬＳ
Ｉの消費電流特性（２゜Ｗ）と定電圧ダイオード特性Ｔ
によ５、ｐ点が動作点となるため、機器の動作範囲内に
存在し、動作に支障を米だすことがない。T... Constant voltage diode characteristics Current Consumption Characteristics To explain the diagram next, under high illuminance, LS is used for both sound and non-sound.
Current consumption characteristics of I (2゜W) and constant voltage diode characteristics T
5. Since point P is the operating point, it exists within the operating range of the device and does not interfere with the operation.
しかしながら、低照度時には、非発音のときＱ点が動作
点となり支障はないが、発音時にはＬＳＩ消費電流の増
大によりＲ点に動作点が移動し、機器の動作電圧範囲外
となり誤動作を引起すという欠点があった。換言すれば
、高照度時には発音動作が可能であるが、低照度時には
発音動作が不可能になるという問題点があった。その為
、従来では、発音動作のオン−オフ動作を行なわせるた
めの専用スイッチを設け、オペレータが照度状況を判断
して発音動作のオン−オンを切替える方法により対処し
てきたが、極めて切替のタイミングが曖昧であシ、又煩
雑であるなどの欠点があった。However, under low illumination conditions, when no sound is being produced, the Q point is the operating point and there is no problem, but when the LSI is producing sound, the operating point moves to the R point due to an increase in LSI current consumption, causing the device to fall outside the operating voltage range and cause malfunctions. There were drawbacks. In other words, there is a problem in that the sound generation operation is possible under high illuminance, but becomes impossible under low illuminance. Conventionally, this has been dealt with by providing a dedicated switch to turn the sound generation on and off, and allowing the operator to judge the illumination situation and switch the sound generation on and off. It had drawbacks such as being vague and complicated.

A second constant voltage element 9 (for example, a constant voltage diode) is inserted in series between them. With this configuration, when surplus power exceeding the required operating power for functions other than the sound generation function is generated by the first and second constant voltage elements during high illuminance, the sound generation function is activated via the second constant voltage element 9. is activated, and the second constant voltage element 9 is activated at -powerful illuminance.
