Description

【発明の詳細な説明】 [産業上の利用分野] 本発明はアラーム時計、タイマ等におけるアラーム音制
御装置に関するものである。
DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an alarm sound control device for an alarm clock, timer, etc.

[従来の技術1 従来のアラーム時計やタイマでは、設定された一定の音
量でしかアラーム音が鳴らない。
[Prior art 1] Conventional alarm clocks and timers only emit an alarm sound at a preset volume.

[発明が解決しようとする問題点] アラーム音の音量が一定のため、周囲が静かな場合には
アラーム音が聞こえるが、騒がしい所ではアラーム音が
聞こえないことがある。
[Problems to be Solved by the Invention] Since the volume of the alarm sound is constant, the alarm sound can be heard when the surroundings are quiet, but the alarm sound may not be heard in a noisy place.

特に、目覚めのため以外の用途で使用する場合、例えば

音が聞こえないことが往々にしてあった。
Especially when the alarm is used for purposes other than waking up, for example when the TV or radio is left on to alert you to a specific time or a fixed amount of time, the noise often prevents you from hearing the alarm. Ta.

本発明は、周囲の騒音に応じた音量のアラーム音を発生
するようにしたものである。
The present invention is designed to generate an alarm sound with a volume corresponding to surrounding noise.

[Example] In the drawings, 1 is a noise detection circuit, 2 is an A/D conversion circuit, 3 is an alarm signal generation circuit, and 4 is a control circuit, each of which receives an alarm signal through one of different resistors 58 to 5d. This is what supplies the sound-producing device.

In the above configuration, the A/D conversion circuit 2 generates an output depending on the noise. Therefore, when the alarm output of the alarm time or the time-up output of the timer is supplied to the terminal AL, an alarm signal is supplied to the sounding device, Q-, through the resistor selected by the Δ/D conversion circuit 2, and the surrounding noise is An alarm sound will be generated at the appropriate volume.

すなわち、周囲が騒がしければ大音量となり、静かであ
れば小音量となる。
That is, if the surroundings are noisy, the volume will be loud, and if the surroundings are quiet, the volume will be low.

[Effects] According to the present invention, the volume of the alarm sound is controlled according to the surrounding noise, so the alarm function can be performed even in noisy conditions, and when it is quiet, no more alarm sound than necessary is generated. It is possible to suppress unnecessary current consumption.
