Description

【0001】
【発明の属する技術分野】
本発明は音響機器に関する。
【0002】
【従来の技術】
従来のテレビ、ラジオ等の音響機器は、設定された音量を維持する。
【0003】
【発明が解決しようとする課題】
従来のテレビ、ラジオ等の音響機器は、設定された音量を維持する機能のみで、聴感に合った音量調整がなされない。
【0004】
本発明は以上のような従来の欠点に鑑み、人間の聴感に合った音量を自動調整するテレビ、ラジオ等の音響機器を提供することを目的としている。
【0005】
本発明の前記ならびにその他の目的と新規な特徴は次の説明を添付図面と照らし合わせて読むと、より完全に明らかになるであろう。
ただし、図面はもっぱら解説のためのものであって、本発明の技術的範囲を限定するものではない。
【0006】
【課題を解決するための手段】
上記目的を達成するために、本発明はテレビ、ラジオ等の音響機器の低周波増幅部の出力音量をコントロールする聴感調整回路部であり、聴感調整回路部は低周波増幅器の波形を監視し検出する波形検出回路部と音響機器の音量調節用ボリュームを制御するボリューム調整回路部から構成される。
【0007】
【発明の実施の形態】
以下、図面に示す実施の形態より、本発明を詳細に説明する。
【0008】
図1は、第1の実施の形態であり、テレビ、ラジオ等の音響装置の内部に組み込んだ場合である。音響機器の低周波増幅部から出力された音声や音楽等の低周波信号を聴感調整回路部内の波形検出回路部において監視し、小さい信号の場合は、音量を上げ、大きい場合は、音量を下げるための制御信号を発生するボリューム調整回路部とで構成されている。
【0009】
図2は、第2の実施の形態であり、前述の実施の形態では、実際の聴衆者の場所においての、聴感に合った音量調整は難しいため、テレビ、ラジオ等の音響装置遠隔操作用リモコンの内部にマイクを内蔵し聴衆者の近傍の音量を検出するための波形検出回路部と検出した音量の制御信号を発生するボリューム調整回路部とで構成されている。
【0010】
【発明の効果】
以上の説明から明らかなように、本発明にあっては次のような効果が得られる。
【0011】
(1)聴衆者は、聴感的に一定の音を聞くことができる。
(2)聴衆者は、ニュース等のアナウンサーが喋る音声と、広告コマーシャル等の音楽を含む音声の音量の変化を意識することなく聴くことができる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to audio equipment.
[0002]
[Prior art]
Conventional audio devices such as televisions and radios maintain a set volume.
[0003]
[Problems to be solved by the invention]
Conventional audio devices such as televisions and radios have only a function of maintaining a set volume, and do not adjust the volume in accordance with the audibility.
[0004]
The present invention has been made in view of the above-described conventional drawbacks, and has as its object to provide an audio device such as a television or a radio that automatically adjusts a volume according to human hearing.
[0005]
The above and other objects and novel features of the present invention will become more completely apparent when the following description is read in conjunction with the accompanying drawings.
However, the drawings are merely for explanation and do not limit the technical scope of the present invention.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention is a hearing adjustment circuit for controlling an output volume of a low frequency amplifier of an audio device such as a television or a radio, and the hearing adjustment circuit monitors and detects a waveform of the low frequency amplifier. And a volume adjustment circuit for controlling a volume adjustment volume of the audio equipment.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.
[0008]
FIG. 1 shows a first embodiment, in which the electronic device is incorporated in an audio device such as a television or a radio. A low-frequency signal, such as voice or music, output from the low-frequency amplifier of the audio equipment is monitored by the waveform detection circuit in the auditory sense adjustment circuit. If the signal is small, the volume is increased, and if it is large, the volume is decreased. And a volume adjustment circuit for generating a control signal for the control.
[0009]
FIG. 2 shows a second embodiment. In the above-described embodiment, since it is difficult to adjust the volume in accordance with the audibility at an actual audience location, a remote control for remote control of an audio device such as a television or a radio is used. It has a built-in microphone and a waveform detection circuit for detecting the volume near the audience, and a volume adjustment circuit for generating a control signal for the detected volume.
[0010]
【The invention's effect】
As is clear from the above description, the following effects can be obtained in the present invention.
[0011]
(1) The audience can hear a certain sound audibly.
(2) The audience can listen to the sound of an announcer such as news and a change in the volume of sound including music such as advertisement commercials without being aware of the change.
[Brief description of the drawings]
FIG. 1 is a block diagram of a first embodiment of the present invention; FIG. 2 is a block diagram of a second embodiment of the present invention;

Claims (2)

音響機器の低周波増幅部の出力が聴感的に一定になるように調整する聴感調整回路を有する音響機器。An audio device having an audibility adjustment circuit for adjusting the output of a low-frequency amplifier of the audio device to be audibly constant. 聴感調整回路を内蔵した音響機器用の遠隔操作用リモコン。Remote control remote control for audio equipment with a built-in hearing adjustment circuit.
