JPH09214858A - Instantaneous sound volume level amplifier circuit - Google Patents

Abstract

PROBLEM TO BE SOLVED: To cancel the unpleasant feeling to a user such as the miss of hearing especially because sounds are missed at night since the sound are listened while lowering a sound volume level at a certain degree when the user usually watches television. SOLUTION: While the user usually watches television, a sound volume level control circuit 1 is controlled and sounds are amplified by an audio amplifier 2 and outputted from a speaker 3. Since the sounds are listened while lowering the sound volume level at a certain degree, the user misses the sounds sometimes especially at night because the sound volume is low. At such a time, an instantaneous amplifier switch circuit 4 is turned 'ON' so that the sound volume level can be instantaneously increased and the unpleasant feeling to the user such as the miss of sounds can be canceled.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a volume level control circuit for a television receiver.

[0002]

2. Description of the Related Art Conventionally, a volume level control circuit has been disclosed in JP-A-1-
The one described in No. 129674 is known. FIG.
FIG. 1 shows a volume level control circuit of a conventional television receiver, 1 is a volume level control circuit, 2 is an audio amplifier, and 3 is a speaker.

[0003]

In this volume level control circuit, since the volume level is usually squeezed when listening to a television, the volume level control circuit may not be heard, especially at night, and is therefore used as a missed voice. It is required to eliminate the discomfort of the person.

[0004]

In order to solve this problem, the present invention is configured to instantly increase the volume level when the voice cannot be heard. As a result, it is possible to eliminate the user's uncomfortable feeling of missing the sound.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is characterized in that when a voice cannot be heard, the volume level is instantly amplified to prevent the voice from being missed. It has the effect of eliminating the user's discomfort that the user cannot hear.

An embodiment of the present invention will be described below with reference to FIG.
This will be described with reference to FIG. (Embodiment 1) FIG. 1 shows an instantaneous volume level amplifier circuit of a television receiver of the present invention. In FIG. 1, 1 is a volume level control circuit, 2 is an audio amplifier, and 3 is a speed amplifier.
F and 4 are composed of instantaneous amplification switch circuits.

The operation of the volume level control circuit of the television receiver configured as described above will be described with reference to FIG.

When watching a normal television, the volume level control circuit 1 is controlled, amplified by an audio amplifier 2 and output by a speaker 3. Since the volume level is squeezed down to some extent, the volume may be too low to hear, especially at night. At this time, by turning on the instantaneous amplification switch circuit 4, the volume level can be instantly increased, and the user's uncomfortable feeling of missing the sound can be eliminated.

[0009]

As described above, according to the present invention, when the voice cannot be heard, the volume level is instantly increased to eliminate the user's uncomfortable feeling of missing the voice. .

Claims (2)

[Claims] 1. An instantaneous volume level amplifying circuit, which raises the volume level instantly when the volume is too low to be heard, such as at night, so as not to miss the voice. 2. The instantaneous volume level amplifier circuit according to claim 1, further comprising: a means for controlling the volume level, a means for amplifying the volume level, and a means for amplifying the volume level instantaneously.
