本発明は、目ざまし時計やクロックラジオのアラーム音
発生装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an alarm sound generating device for an alarm clock or a clock radio.
従来の技術
従来、目ざまし時計のアラーム音発生方式として、され
やかな目ざめのために徐々にアラーム音を発生させる”
テンダーアラーム′″という方式が知られている。Conventional technology Traditionally, the alarm sound generation method for alarm clocks has been to generate an alarm sound gradually in order to wake up gently.
A method called tender alarm''' is known.
このテンダーアラーム方式は、第５図に示すように、ア
ラーム信号発生部５１の出力信号５６と、断続信号発゛
生部５２の出力信号５７をムＮＤ回路５３に入力し、出
力６８を得る。この出力６８は増幅部５４全通してスピ
ーカ５６より報じられる。In this tender alarm method, as shown in FIG. 5, an output signal 56 of an alarm signal generating section 51 and an output signal 57 of an intermittent signal generating section 52 are inputted to a ND circuit 53 to obtain an output 68. This output 68 is transmitted through the entire amplifier section 54 and is reported from the speaker 56.
断続信号のパルス数を時間と共に増加させることによシ
、最初は、「ビピッ」というやさしいアラーム音である
が、時間と共に、「ピピピッ」「ビピピピッ」と増加し
て行き、ついには連続音となり、最大のアラーム効果を
得ることが出来る。By increasing the number of pulses of the intermittent signal over time, the alarm sound starts out as a gentle beep, but as time passes, it increases to beeps and beeps, and finally becomes a continuous sound. Maximum alarm effect can be obtained.
発明が解決しようとする問題点
ところが、この方式ではアラーム音を発する時間は変化
するが、音量が一定であるために、敏感な人にとっては
、テンダーアラームの効果を発せず、されやかな目ざめ
を得ることが困難になるという問題を有していた。Problems to be Solved by the Invention However, with this method, the time at which the alarm sound is emitted varies, but the volume is constant, so for sensitive people, the effect of the tender alarm is not emitted, and it is difficult to wake up gently. The problem was that it was difficult to obtain.
本発明は、上記問題点に鑑み、アラーム音の周波数と音
量を変化せしめ、真のされやかな目ざめの効果を持たせ
たアラーム音発生装置を提供するものである。In view of the above-mentioned problems, the present invention provides an alarm sound generating device that changes the frequency and volume of the alarm sound to provide a truly gentle wake-up effect.
問題点を解決するための手段
上記問題点を解決するために本発明のアラーム音発生装
置は、時間と共に周波数の変化する信号発生回路の出力
を、周波数特性を持った結合回路を通して、出力増幅回
路に接続することを特徴とするものである。Means for Solving the Problems In order to solve the above-mentioned problems, the alarm sound generating device of the present invention connects the output of a signal generation circuit whose frequency changes with time to an output amplification circuit through a coupling circuit having frequency characteristics. It is characterized by being connected to.
作用
本発明のアラーム音発生装置は、上記の構成によって、
周波数と共に音量が変化するので、低い周波数でしかも
小さな音量で目ざましが始まシ、徐々に高い周波数で大
きな音量へと時間と共に移行する。このため、敏感な人
にとっても、真のされやかな目ざましの効果を持たせた
アラーム音を発生することが出来るものである。Function: The alarm sound generating device of the present invention has the above configuration.
Since the volume changes with the frequency, the alarm starts at a low frequency and low volume, and gradually moves to a high frequency and a high volume over time. Therefore, even for sensitive people, it is possible to generate an alarm sound that has a truly gentle wake-up effect.
