Abstract

PURPOSE:To facilitate an easy hearing, by increasing the amplification factor as the level of the voice signal is lowered in cas when the voice signal has a level lower than the prescribed value. CONSTITUTION:The voice of the TV signal received by the antenna 1 is delivered through the speaker 10 via the frequency discriminator 8 and the low frequency amplifying part 9. The switch S1 is set at the side of resistane R when the variable resistor 11 sets the sound volume over the prescribed level. While in case when the resistor 11 sets the sound volume under the prescribed level, the switch S1 is switched to the side of transmission line 14. In this case, the level detection circuit 16 increases the amplification factor of the amplifier 15 as the level of the detected voice signal reduces. Accordingly the voice signal of a low level can be heard even when the sound volume is lowered greatly.
