Abstract

PURPOSE:To eliminate necessity of volume adjustment to make holding alarm tone small by providing a timer circuit that counts a fixed time after a push switch is depressed, and returns the volume of a speaker to the former state. CONSTITUTION:When a telephone set 1 receives a holding alarm signal, if a push switch 4 is depressed, power sent to a speaker 7 is limited by the action of a volume adjusting circuit 5, and the volume is turned down. Simultaneously with depressing of the switch 4, a timer circuit 6 starts operation. The timer circuit 6 counts pulses generated periodically inside until previously set time, and when the set time lapsed, controls the volume control circuit 5 to return the volume of the speaker 7 to the former state. Accordingly, by depressing the switch 4, the volume of the speaker 7 can be turned down temporarily, and time for volume adjustment by a variable resistance is saved.

In this case, the hold alarm sound was annoying, so it was necessary to lower the volume of the speaker. However, if the volume is carelessly kept low, it becomes difficult to hear ringtones, other alarm sounds, and extension calls from the speaker.

An electronic device comprising: an audio control means for limiting the volume of the speaker in conjunction with a push switch; and a means for canceling the volume restriction of the speaker by the volume control means after a certain period of time from when the push switch is pressed. A keypad telephone is obtained.

The output of which audio circuit is the volume adjustment circuit 5 (* is sent to a handset (not shown).The volume adjustment circuit 5 outputs the hold alarm signal among the outputs of the audio circuit 3 when the button switch 4 is pressed. The amplitude is limited to reduce the volume of the speaker 7. The timer circuit 4 sets the time during which the Furu town adjustment circuit 5 limits the volume.

When the switch 4 is pressed, the power sent to the speaker 7 is restricted by the function of the volume control circuit 5, and the volume is lowered.Also, the timer circuit 6 starts operating at the same time as the button switch is pressed. The timer circuit counts internally periodically emitted pulses up to a preset time.
When the set time has elapsed, the volume control circuit 5 is controlled to return the volume of the speaker 7 to the original level. Therefore, by pressing the button switch 4, the volume of the speaker 7 can be temporarily lowered, thereby eliminating the trouble of adjusting the volume using the volume.
