The zener diode is connected directly to the 9 volt supply.
Hi buddy there is basic flaw in circuit. Resistor Resistor is a passive component used to control current in a circuit.
Um35611 Capacitor is a passive component used to store charge. Capacitors offer infinite reactance to zero frequency so they are used for blocking DC components or bypassing the AC signals. When an electric signal is applied to the input pin of speaker, it generates sound waves. Liquid level Alarm using transistor and timer IC. This voltage is called Breakdown Voltage or Zener Knee voltage.
UM3561 Siren Sound Generator COM22
Speaker A loudspeaker or “speaker” is a transducer hm3561 converts electrical energy into acoustical energy. When anyone presses the switch, the signals are provided to the base of the transistor T1.
UM UMA Audio IC
The charge q stored in a capacitor is the product of its capacitance C value and the voltage V applied to it. It will help your sound based or alarm based electronic project.
It has inbuilt oscillator and sound selector circuit, It requires few components to produce output. Step-By-Step 1 2 3 u3m561.
Group all Htabs Electronics. This high is provided to Darlington pair transistor T4, T5 and the loudspeaker connected to it starts sounding.
UM3561 IC Based Security Alarm
Its resistance is given by the ratio of voltage applied across its terminals to the current passing through it. UM Pin diagram and Pin description is given below, taken from its Datasheet: Your email address will not be published.

While building circuits many times we need to generate sounds like a musical sound or some kind of alerting sound. All the diodes allow flow of current in only one direction forwardbut Zener diode can allow current in reverse direction if the voltage goes beyond a certain limit. A loudspeaker or “speaker” is a transducer that converts electrical energy into acoustical energy.
You can also increase the number of switches to increase the capability of the circuit. With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work. It is generally used in alarms and toys. Leave Open for Normal Operations.
